A webcam is a video camera which is designed to record or stream to a computer or computer network . They are primarily used in video telephony , live streaming and social media , and security . Webcams can be built-in computer hardware or peripheral devices , and are commonly connected to a device using USB or wireless protocols .
119-394: BTS World (stylized in all caps) is a mobile video game developed by South Korean studio Takeone Company Corp and published by Netmarble . Players take the role of BTS ' manager, going through various journeys with each of the seven members from 2012, before their debut, to 2019. The game was released to iOS and Android systems in over 175 countries on June 26, 2019. BTS World
238-412: A Trojan Horse program or other similar spyware programs. Cameras such as Apple 's older external iSight cameras include lens covers to thwart this. Some webcams have built-in hardwired LED indicators that light up whenever the camera is active, sometimes only in video mode. However, it is possible, depending on the circuit design of a webcam, for malware to circumvent the indicator and activate
357-408: A computer game or just a game , is an electronic game that involves interaction with a user interface or input device (such as a joystick , controller , keyboard , or motion sensing device) to generate visual feedback from a display device , most commonly shown in a video format on a television set , computer monitor , flat-panel display or touchscreen on handheld devices , or
476-547: A serial port , at a cost of $ 100. Jon Garber, the designer of the device, had wanted to call it the "Mac-camera", but was overruled by Connectix's marketing department; a version with a PC-compatible parallel port and software for Microsoft Windows was launched in October 1995. The original Quick Cam provided 320x240-pixel resolution with a grayscale depth of 16 shades at 60 frames per second, or 256 shades at 15 frames per second. These cam were tested on several Delta II launch using
595-457: A teletype printer , audio speaker , or similar device. This also distinguished from many handheld electronic games like Merlin which commonly used LED lights for indicators but did not use these in combination for imaging purposes. "Computer game" may also be used as a descriptor, as all these types of games essentially require the use of a computer processor, and in some cases, it is used interchangeably with "video game". Particularly in
714-638: A virtual reality headset . These games are addictive and can lead to the release of dopamine in the addict's synapses. Most modern video games are audiovisual , with audio complement delivered through speakers or headphones , and sometimes also with other types of sensory feedback (e.g., haptic technology that provides tactile sensations). Some video games also allow microphone and webcam inputs for in-game chatting and livestreaming . Video games are typically categorized according to their hardware platform , which traditionally includes arcade video games , console games , and computer (PC) games ;
833-535: A "webcam". Aggregator websites have also been created, providing thousands of live video streams or up-to-date still pictures, allowing users to find live video streams based on location or other criteria. In the late 1990s, Microsoft NetMeeting was the only videoconferencing software on PC in widespread use, making use of webcams. In the following years, instant messaging clients started adding webcam support: Yahoo Messenger introduced this with version 5.5 in 2002, allowing video calling in 20 frames per second using
952-544: A DEC PDP-1 computer in 1962. Each game has different means of display: NIMROD has a panel of lights to play the game of Nim , OXO has a graphical display to play tic-tac-toe, Tennis for Two has an oscilloscope to display a side view of a tennis court, and Spacewar! has the DEC PDP-1's vector display to have two spaceships battle each other. These inventions laid the foundation for modern video games. In 1966, while working at Sanders Associates , Ralph H. Baer devised
1071-588: A Raspberry Pi as MotionEyeOs, or afterwards on Raspbian as well. MotionEye can also be set up on Debian, Raspbian is a variant of Debian. MotionEye V4.1.1 ( Aug '21 ) can only run on Debian 10 Buster ( oldstable ) and Python 2.7. Newer versions such as 3.X are not supported at this point of time according to Ccrisan, foundator and author of MotionEye. Various software tools in wide use can be employed to take video and pictures, such as PicMaster and Microsoft's Camera app (for use with Windows operating systems), Photo Booth ( Mac ), or Cheese (with Unix systems). For
1190-437: A combination of the limitations of the game platform and display device and the program efficiency of the game itself. The game's output can range from fixed displays using LED or LCD elements, text-based games , two-dimensional and three-dimensional graphics, and augmented reality displays. The game's graphics are often accompanied by sound produced by internal speakers on the game platform or external speakers attached to
1309-439: A couple of seconds and then all the frames of the video are "stacked" together to obtain a still image of respectable contrast. A webcam's CCD response is linearly proportional to the incoming light. Therefore, webcams are suitable to record laser beam profiles, after the lens is removed. The resolution of a laser beam profiler depends on the pixel size. Commercial webcams are usually designed to record color images. The size of

Like all software, video games usually undergo quality testing before release to assure there are no bugs or glitches in the product, though frequently developers will release patches and updates . With
1547-413: A few specific models of webcams are very popular to photograph the night sky by astronomers and astro photographers. Mostly, these are manual-focus cameras and contain an old CCD array instead of comparatively newer CMOS array. The lenses of the cameras are removed and then these are attached to telescopes to record images, video, still, or both. In newer techniques, videos of very faint objects are taken for
1666-414: A fictional piece of technology from Star Trek , arguing for the video game as a medium in which the player is allowed to become another person, and to act out in another world. This image of video games received early widespread popular support, and forms the basis of films such as Tron , eXistenZ and The Last Starfighter . Ludologists break sharply and radically from this idea. They argue that
1785-432: A game following its initial release. Several games offer players the ability to create user-generated content to share with others to play. Other games, mostly those on personal computers, can be extended with user-created modifications or mods that alter or add onto the game; these often are unofficial and were developed by players from reverse engineering of the game, but other games provide official support for modding
1904-415: A letter dated July 10, 1972. In the letter, Bushnell uses the term "video game" twice. Per video game historian Keith Smith, the sudden appearance suggested that the term had been proposed and readily adopted by those in the field. Around March 1973, Ed Adlum, who ran Cashbox ' s coin-operated section until 1972 and then later founded RePlay Magazine , covering the coin-op amusement field, in 1975, used
2023-504: A limited number of platforms, and exclusivity to a platform or brand is used by platform holders as a competitive edge in the video game market. However, games may be developed for alternative platforms than intended, which are described as ports or conversions. These also may be remasters - where most of the original game's source code is reused and art assets, models, and game levels are updated for modern systems – and remakes, where in addition to asset improvements, significant reworking of

The regulations vary from country to country but generally are voluntary systems upheld by vendor practices, with penalty and fines issued by the ratings body on the video game publisher for misuse of the ratings. Among the major content rating systems include: Additionally,
2261-750: A more complete list see Comparison of webcam software . The most popular use of webcams is the establishment of video links , permitting computers to act as videophones or videoconference stations . For example, Apple 's iSight camera, which is built into Apple laptops, iMacs and a majority of iPhones , can be used for video chat sessions, using the Messages instant messaging program. Other popular uses include security surveillance, computer vision , video broadcasting, and for recording social videos. Webcams can be added to instant messaging , text chat services such as AOL Instant Messenger , and VoIP services such as Skype , one-to-one live video communication over
2380-551: A platform, the hardware which contains computing elements, to process player interaction from some type of input device and displays the results to a video output display. Video games require a platform, a specific combination of electronic components or computer hardware and associated software , to operate. The term system is also commonly used. These platforms may include multiple brandsheld by platform holders , such as Nintendo or Sony, seeking to gain larger market shares. Games are typically designed to be played on one or
2499-464: A relatively recent development in the humanities. The two most visible schools in this emerging field are ludology and narratology . Narrativists approach video games in the context of what Janet Murray calls "Cyberdrama". That is to say, their major concern is with video games as a storytelling medium, one that arises out of interactive fiction . Murray puts video games in the context of the Holodeck ,

#17328725945842618-455: A service . Today, video game development requires numerous interdisciplinary skills, vision , teamwork , and liaisons between different parties, including developers , publishers , distributors , retailers , hardware manufacturers, and other marketers, to successfully bring a game to its consumers. As of 2020 , the global video game market had estimated annual revenues of US$ 159 billion across hardware, software, and services, which
2737-590: A similar version running in a smaller coin-operated arcade cabinet using a less expensive computer. This was released as Computer Space , the first arcade video game , in 1971. Bushnell and Dabney went on to form Atari, Inc. , and with Allan Alcorn , created their second arcade game in 1972, the hit ping pong -style Pong , which was directly inspired by the table tennis game on the Odyssey. Sanders and Magnavox sued Atari for infringement of Baer's patents, but Atari settled out of court, paying for perpetual rights to
2856-507: A single silicon chip to save space and manufacturing costs. Most webcams feature built-in microphones to make video calling and videoconferencing more convenient. Typical interfaces used by articles marketed as a "webcam" are USB , Ethernet and IEEE 802.11 (denominated as IP camera ). Further interfaces such as e.g. Composite video , S-Video or FireWire were also available. The USB video device class (UVC) specification allows inter-connectivity of webcams to computers without
2975-515: A system to play a basic table tennis game on a television screen. With the company's approval, Baer created the prototype known as the "Brown Box." Sanders patented Baer’s innovations and licensed them to Magnavox , which commercialized the technology as the first home video game console , the Magnavox Odyssey , released in 1972. Separately, Nolan Bushnell and Ted Dabney , inspired by seeing Spacewar! running at Stanford University , devised
3094-435: A variety of communication protocols including CDMA, TDMA, GSM and HF. Videoconferencing via computers already existed, and at the time client-server based videoconferencing software such as CU-SeeMe had started to become popular. The first widely known laptop with integrated webcam option, at a pricepoint starting at US$ 12,000, was an IBM RS/6000 860 laptop and its related ThinkPad 850 , released in 1996. One of

While many games rely on emergent principles , video games commonly present simulated story worlds where emergent behavior occurs within the context of the game. The term "emergent narrative" has been used to describe how, in a simulated environment, storyline can be created simply by "what happens to
3332-412: A video game is first and foremost a game, which must be understood in terms of its rules, interface, and the concept of play that it deploys. Espen J. Aarseth argues that, although games certainly have plots, characters, and aspects of traditional narratives, these aspects are incidental to gameplay. For example, Aarseth is critical of the widespread attention that narrativists have given to the heroine of
3451-441: A view on a Web page to an unknown public. For less than US$ 100 in 2012, a three-dimensional space webcam became available, producing videos and photos in 3D anaglyph image with a resolution up to 1280 × 480 pixels. Viewers must use 3D glasses to see the effect of three dimensional image. With remote work entering the mainstream, the built-in cameras of average laptops were sometimes considered inadequate. Consequently, during
3570-457: A way to distinguish them from console games , arcade games , or mobile games . Other terms such as "television game", "telegame", or "TV game" had been used in the 1970s and early 1980s, particularly for home gaming consoles that rely on connection to a television set . However, these terms were also used interchangeably with "video game" in the 1970s, primarily due to "video" and "television" being synonymous. In Japan , where consoles like

However, a color pixel consists of four black and white pixels each equipped with a color filter (for details see Bayer filter ). Although these color filters work well in the visible, they may be rather transparent in the near infrared. By switching a webcam into the Bayer-mode it is possible to access the information of

Around the turn of the 21st century, computer hardware manufacturers began building webcams directly into laptop and desktop screens, thus eliminating the need to use an external USB or FireWire camera. Gradually webcams came to be used more for telecommunications, or videotelephony , between two people, or among several people, than for offering
3927-411: A word from Billboard ' s description of movie jukeboxes, Adlum started to refer to this new breed of amusement machine as 'video games.' The phrase stuck." Adlum explained in 1985 that up until the early 1970s, amusement arcades typically had non-video arcade games such as pinball machines and electro-mechanical games . With the arrival of video games in arcades during the early 1970s, there

The game is based on conversations and choices that impact the later chapters. The player can also style the characters and play a card game to achieve a specific score. The game uses real photos and voice recordings of the BTS members. Its official website has galleries of photos and videos of
4165-431: Is a video game "appears highly eclectic and diverse". The gameplay experience varies radically between video games, but many common elements exist. Most games will launch into a title screen and give the player a chance to review options such as the number of players before starting a game. Most games are divided into levels which the player must work the avatar through, scoring points , collecting power-ups to boost
4284-459: Is frequently a cross-disciplinary field. Video game developers , as employees within this industry are commonly referred to, primarily include programmers and graphic designers . Over the years, this has expanded to include almost every type of skill that one might see prevalent in the creation of any movie or television program, including sound designers , musicians, and other technicians; as well as skills that are specific to video games, such as
4403-421: Is from 1947—a " cathode-ray tube amusement device " was filed for a patent on 25 January 1947, by Thomas T. Goldsmith Jr. and Estle Ray Mann, and issued on 14 December 1948, as U.S. Patent 2455992. Inspired by radar display technology, it consists of an analog device allowing a user to control the parabolic arc of a dot on the screen to simulate a missile being fired at targets, which are paper drawings fixed to
4522-548: Is mostly isolated from the rest of the world due to the government's censorship, and all games published there must adhere to strict government review, disallowing content such as smearing the image of the Chinese Communist Party . Foreign games published in China often require modification by developers and publishers to meet these requirements. Video game development and authorship, much like any other form of entertainment,

The SGI Indy , released in 1993, is the first commercial computer to have a standard video camera, and the first SGI computer to have standard video inputs. The maximum supported input resolution is 640×480 for NTSC or 768×576 for PAL . A fast machine is required to capture at either of these resolutions, though; an Indy with slower R4600PC CPU, for example, may require
4760-447: Is the primary means which one interacts with a video game. The narrative setting does not impact gameplay; a shooter game is still a shooter game, regardless of whether it takes place in a fantasy world or in outer space. An exception is the horror game genre, used for games that are based on narrative elements of horror fiction , the supernatural , and psychological horror . Genre names are normally self-describing in terms of

The video game market is also a major influence behind the electronics industry , where personal computer component, console, and peripheral sales, as well as consumer demands for better game performance, have been powerful driving factors for hardware design and innovation. Early video games use interactive electronic devices with various display formats. The earliest example

4998-515: The Berne Convention . This typically only applies to the underlying code, as well as to the artistic aspects of the game such as its writing, art assets, and music. Gameplay itself is generally not considered copyrightable; in the United States among other countries, video games are considered to fall into the idea–expression distinction in that it is how the game is presented and expressed to
5117-751: The COVID-19 pandemic caused a shortage of webcams due to the increased number of people working from home . First developed in 1991, a webcam was pointed at the Trojan Room coffee pot in the Cambridge University Computer Science Department (initially operating over a local network instead of the web). The camera was finally switched off on August 22, 2001. The final image captured by the camera can still be viewed at its homepage. The oldest continuously operating webcam, San Francisco State University 's FogCam , has run since 1994 and
5236-421: The COVID-19 pandemic , a shortage of external webcams in retail occurred. Most laptops before and during the pandemic were made with cameras capping out at 720p recording quality at best, compared to the industry standard of 1080p or 4K seen in smartphones and televisions from the same period. The backlog on new developments for built-in webcams is the result of a design flaw with laptops being too thin to support
5355-637: The Clue VCR Mystery Game which required players to watch VCR clips between turns. To distinguish between these two, video games are considered to require some interactivity that affects the visual display. Most video games tend to feature some type of victory or winning conditions, such as a scoring mechanism or a final boss fight. The introduction of walking simulators ( adventure games that allow for exploration but lack any objectives) like Gone Home , and empathy games (video games that tend to focus on emotion) like That Dragon, Cancer brought

Other terms used include digital game, for example, by the Australian Bureau of Statistics . However, the term "computer game" can also be used to more specifically refer to games played primarily on personal computers or other types of flexible hardware systems (also known as PC game ), as
5593-485: The Unterhaltungssoftware Selbstkontrolle ( Entertainment Software Self-Regulation ) would refuse to classify, and thus allow sale, of any game depicting Nazi imagery, and thus often requiring developers to replace such imagery with fictional ones. This ruling was relaxed in 2018 to allow for such imagery for "social adequacy" purposes that applied to other works of art. China's video game segment

Following the crash, the industry matured, was dominated by Japanese companies such as Nintendo , Sega , and Sony , and established practices and methods around the development and distribution of video games to prevent a similar crash in the future, many of which continue to be followed. In

However, at times and more frequently at the onset of the industry, developers would intentionally create video game clones of successful games and game hardware with few changes, which led to the flooded arcade and dedicated home console market around 1978. Cloning is also a major issue with countries that do not have strong intellectual property protection laws, such as within China . The lax oversight by China's government and
5950-409: The game designer . All of these are managed by producers . In the early days of the industry, it was more common for a single person to manage all of the roles needed to create a video game. As platforms have become more complex and powerful in the type of material they can present, larger teams have been needed to generate all of the art, programming, cinematography, and more. This is not to say that

The first consumer video game was the arcade video game Computer Space in 1971. In 1972 came the iconic hit game Pong and the first home console , the Magnavox Odyssey . The industry grew quickly during the "golden age" of arcade video games from the late 1970s to early 1980s but suffered from

Today, the video game industry is predominantly led by major companies in North America (primarily the United States and Canada), Europe, and southeast Asia including Japan, South Korea, and China. Hardware production remains an area dominated by Asian companies either directly involved in hardware design or part of the production process, but digital distribution and indie game development of

The advent of the Internet brought digital distribution as a viable means to distribute games, and contributed to the growth of more riskier, experimental independent game development as an alternative to triple-A games in
6426-462: The 1993 game . A hierarchy of game genres exist, with top-level genres like "shooter game" and "action game" that broadly capture the game's main gameplay style, and several subgenres of specific implementation, such as within the shooter game first-person shooter and third-person shooter . Some cross-genre types also exist that fall until multiple top-level genres such as action-adventure game . A video game's mode describes how many players can use
6545-626: The 2000s, the core industry centered on " AAA " games, leaving little room for riskier experimental games. Coupled with the availability of the Internet and digital distribution , this gave room for independent video game development (or " indie games ") to gain prominence into the 2010s. Since then, the commercial importance of the video game industry has been increasing. The emerging Asian markets and proliferation of smartphone games in particular are altering player demographics towards casual gaming and increasing monetization by incorporating games as

Also the camera components are more expensive and not a high level of demand for this feature, Smartphones started to be used as a backup option or webcam replacement, with kits including lighting and tripods or downloadable apps. Image sensors can be CMOS or CCD , the former being dominant for low-cost cameras, but CCD cameras do not necessarily outperform CMOS-based cameras in
6783-450: The Internet for video chat has also caused issues. For example, moderation system of various video chat websites such as Omegle has been criticized as being ineffective, with sexual content still rampant. In a 2013 case, the transmission of nude photos and videos via Omegle from a teenage girl to a schoolteacher resulted in a child pornography charge. The popularity of webcams among teenagers with Internet access has raised concern about
6902-405: The Internet has now reached millions of mainstream PC users worldwide. Improved video quality has helped webcams encroach on traditional video conferencing systems. New features such as automatic lighting controls, real-time enhancements (retouching, wrinkle smoothing and vertical stretch), automatic face tracking and autofocus, assist users by providing substantial ease-of-use, further increasing
7021-637: The Internet or other communication methods as well as cloud gaming alleviate the need for any physical media. In some cases, the media serves as the direct read-only memory for the game, or it may be the form of installation media that is used to write the main assets to the player's platform's local storage for faster loading periods and later updates. Games can be extended with new content and software patches through either expansion packs which are typically available as physical media, or as downloadable content nominally available via digital distribution. These can be offered freely or can be used to monetize

In one well-publicised case, a computer e-mailed images of the burglar during the theft of the computer, enabling the owner to give police a clear picture of the burglar's face even after the computer had been stolen. In December 2011, Russia announced that 290,000 Webcams would be installed in 90,000 polling stations to monitor the 2012 Russian presidential election . Webcams may be installed at places such as childcare centres, offices, shops and private areas to monitor security and general activity. With very-low-light capability,

#17328725945847378-728: The age of the "one-man shop" is gone, as this is still sometimes found in the casual gaming and handheld markets, where smaller games are prevalent due to technical limitations such as limited RAM or lack of dedicated 3D graphics rendering capabilities on the target platform (e.g., some PDAs ). Video games are programmed like any other piece of computer software. Prior to the mid-1970s, arcade and home consoles were programmed by assembling discrete electro-mechanical components on circuit boards, which limited games to relatively simple logic. By 1975, low-cost microprocessors were available at volume to be used for video game hardware, which allowed game developers to program more detailed games, widening

This information is relayed to the player through a type of on-screen user interface such as a heads-up display atop the rendering of the game itself. Taking damage will deplete their avatar's health , and if that falls to zero or if the avatar otherwise falls into an impossible-to-escape location,

Various companies sell sliding lens covers and stickers that allow users to retrofit a computer or smartphone to close access to the camera lens as needed. One such company reported having sold more than 250,000 such items from 2013 to 2016. However, any opaque material will work just as well. The process of attempting to hack into

Similar control sets are built into handheld consoles and onto arcade cabinets. Newer technology improvements have incorporated additional technology into the controller or the game platform, such as touchscreens and motion detection sensors that give more options for how
8092-423: The difficulty for foreign companies to take Chinese entities to court had enabled China to support a large grey market of cloned hardware and software systems. The industry remains challenged to distinguish between creating new games based on refinements of past successful games to create a new type of gameplay, and intentionally creating a clone of a game that may simply swap out art assets. The early history of

When I play, I don't even see her body, but see through it and past it." Simply put, ludologists reject traditional theories of art because they claim that the artistic and socially relevant qualities of

Within the latter category, multiplayer games can be played in a variety of ways, including locally at the same device, on separate devices connected through a local network such as LAN parties , or online via separate Internet connections. Most multiplayer games are based on competitive gameplay, but many offer cooperative and team-based options as well as asymmetric gameplay . Online games use server structures that can also enable massively multiplayer online games (MMOs) to support hundreds of players at
8449-406: The game can also be exploited. On some consoles, cheat cartridges allow players to execute these cheat codes, and user-developed trainers allow similar bypassing for computer software games. Both of which might make the game easier, give the player additional power-ups, or change the appearance of the game. To distinguish from electronic games, a video game is generally considered to require

These also may be in the form of a passage that can be written down and reentered at the title screen. Product flaws include software bugs which can manifest as glitches which may be exploited by the player; this is often the foundation of speedrunning a video game. These bugs, along with cheat codes , Easter eggs , and other hidden secrets that were intentionally added to
8687-463: The game's official theme song and the soundtrack's lead single, " Heartbeat ", was revealed in-game after its release. Before being released, the game received significant media coverage. CNBC said the game "will offer opportunities for microtransactions." MTV reports for people who are not familiar with the band, "the game could become a powerful learning tool for anyone just getting into their music." Video game A video game , also known as
8806-501: The game. Video game can use several types of input devices to translate human actions to a game. Most common are the use of game controllers like gamepads and joysticks for most consoles, and as accessories for personal computer systems along keyboard and mouse controls. Common controls on the most recent controllers include face buttons, shoulder triggers, analog sticks , and directional pads ("d-pads") . Consoles typically include standard controllers which are shipped or bundled with
8925-399: The game. By definition, all video games are intended to output graphics to an external video display, such as cathode-ray tube televisions, newer liquid-crystal display (LCD) televisions and built-in screens, projectors or computer monitors , depending on the type of platform the game is played on. Features such as color depth , refresh rate , frame rate , and screen resolution are
9044-560: The game. Today, many games are built around a game engine that handles the bulk of the game's logic, gameplay, and rendering. These engines can be augmented with specialized engines for specific features, such as a physics engine that simulates the physics of objects in real-time. A variety of middleware exists to help developers access other features, such as playback of videos within games, network-oriented code for games that communicate via online services, matchmaking for online games, and similar features. These features can be used from
9163-661: The group's strong fanbase "leads to a good potential market for creating a brand-new game." The game is based on the members' true personalities. The game features original music from the group. An accompanying soundtrack album, BTS World: Original Soundtrack , was released worldwide on June 28, 2019. The soundtrack was supported by three collaboration singles: " Dream Glow " by Jin , Jimin , and Jungkook featuring British singer Charli XCX (June 7), " A Brand New Day " by J-Hope and V featuring Swedish singer Zara Larsson (June 14), and " All Night " by RM and Suga featuring American rapper Juice Wrld (June 21). On June 26,
9282-485: The growth of the size of development teams in the industry, the problem of cost has increased. Development studios need the best talent, while publishers reduce costs to maintain profitability on their investment. Typically, a video game console development team ranges from 5 to 50 people, and some exceed 100. In May 2009, Assassin's Creed II was reported to have a development staff of 450. The growth of team size combined with greater pressure to get completed projects into
9401-586: The idea of games that did not have any such type of winning condition and raising the question of whether these were actually games. These are still commonly justified as video games as they provide a game world that the player can interact with by some means. The lack of any industry definition for a video game by 2021 was an issue during the case Epic Games v. Apple which dealt with video games offered on Apple's iOS App Store . Among concerns raised were games like Fortnite Creative and Roblox which created metaverses of interactive experiences, and whether
9520-478: The image from the sensor and transmit it to the host computer. Most webcams come with a controller that translates video over USB from Sonix, Suyin, Ricoh , Realtek or others. Typically, each frame is transmitted uncompressed in RGB or YUV or compressed as JPEG . Some cameras, such as mobile-phone cameras , use a CMOS sensor with supporting electronics "on die", i.e. the sensor and the support electronics are built on
9639-575: The input resolution to be reduced before storage or processing. However, the Vino hardware is capable of DMAing video fields directly into the frame buffer with minimal CPU overhead. The first widespread commercial webcam, the black-and-white QuickCam , entered the marketplace in 1994, created by the U.S. computer company Connectix . QuickCam was available in August 1994 for the Apple Macintosh , connecting via
9758-450: The larger " AAA " game studios, and are often experiments in gameplay and art style. Indie game development is aided by the larger availability of digital distribution, including the newer mobile gaming market, and readily-available and low-cost development tools for these platforms. Although departments of computer science have been studying the technical aspects of video games for years, theories that examine games as an artistic medium are
9877-713: The larger game and the individual experiences themselves were games or not in relation to fees that Apple charged for the App Store. Judge Yvonne Gonzalez Rogers , recognizing that there was yet an industry standard definition for a video game, established for her ruling that "At a bare minimum, video games appear to require some level of interactivity or involvement between the player and the medium" compared to passive entertainment like film, music, and television, and "videogames are also generally graphically rendered or animated, as opposed to being recorded live or via motion capture as in films or television". Rogers still concluded that what
9996-417: The late 2000s and which has continued to grow as a significant portion of the video game industry. Video games have a large network effect that draw on many different sectors that tie into the larger video game industry. While video game developers are a significant portion of the industry, other key participants in the market include: The industry itself grew out from both the United States and Japan in
10115-570: The late 2000s has allowed game developers to flourish nearly anywhere and diversify the field. Webcam Webcams have been used on the Internet as early as 1993, and the first widespread commercial one became available in 1994. Early webcam usage on the Internet was primarily limited to stationary shots streamed to web sites. In the late 1990s and early 2000s, instant messaging clients added support for webcams, increasing their popularity in video conferencing. Computer manufacturers later started integrating webcams into laptop hardware. In 2020,
10234-452: The latter also encompasses LAN games , online games , and browser games . More recently, the video game industry has expanded onto mobile gaming through mobile devices (such as smartphones and tablet computers ), virtual and augmented reality systems, and remote cloud gaming . Video games are also classified into a wide range of genres based on their style of gameplay and target audience . The first video game prototypes in
10353-566: The low-price range. Most consumer webcams are capable of providing VGA -resolution video at a frame rate of 30 frames per second. Many newer devices can produce video in multi- megapixel resolutions, and a few can run at high frame rates such as the PlayStation Eye , which can produce 320×240 video at 120 frames per second. Most image sensors are sourced from Omnivision or Sony . As webcams evolved simultaneously with display technologies, USB interface speeds and broadband internet speeds,
10472-659: The major content system provides have worked to create the International Age Rating Coalition (IARC), a means to streamline and align the content ratings system between different region, so that a publisher would only need to complete the content ratings review for one provider, and use the IARC transition to affirm the content rating for all other regions. Certain nations have even more restrictive rules related to political or ideological content. Within Germany, until 2018,
10591-462: The market to begin recouping production costs has led to a greater occurrence of missed deadlines, rushed games, and the release of unfinished products. While amateur and hobbyist game programming had existed since the late 1970s with the introduction of home computers, a newer trend since the mid-2000s is indie game development . Indie games are made by small teams outside any direct publisher control, their games being smaller in scope than those from
10710-405: The market. Due to loss of publishing control and oversaturation of the market, the North American home video game market crashed in 1983 , dropping from revenues of around $ 3 billion in 1983 to $ 100 million by 1985. Many of the North American companies created in the prior years closed down. Japan's growing game industry was briefly shocked by this crash but had sufficient longevity to withstand
10829-421: The members as the game characters. Another mode, called "Another Story", has similar gameplay but different stories, as each focuses on the player and only one member of BTS as if they were not together back then. Based on the descriptions on the game's official website, there are seven different characters in "Another Story". It was reported that BTS World was developing for two years. Netmarble claimed that
10948-420: The most common in consumer-grade webcams being a plastic lens that can be manually moved in and out to focus the camera. Fixed-focus lenses , which have no provision for adjustment, are also available. As a camera system's depth of field is greater for small image formats and is greater for lenses with a large f-number (small aperture), the systems used in webcams have a sufficiently large depth of field that
11067-417: The most widely reported-on webcam sites was JenniCam , created in 1996, which allowed Internet users to observe the life of its namesake constantly, in the same vein as the reality TV series Big Brother , launched four years later. Other cameras are mounted overlooking bridges, public squares, and other public places, their output made available on a public web page in accordance with the original concept of
11186-500: The need for proprietary device drivers. Various proprietary as well as free and open-source software is available to handle the UVC stream. One could use Guvcview or GStreamer and GStreamer-based software to handle the UVC stream. Another could use multiple USB cameras attached to the host computer the software resides on, and broadcast multiple streams at once over (Wireless) Ethernet, such as MotionEye. MotionEye can either be installed onto
11305-774: The original game and possibly from scratch is performed. The list below is not exhaustive and excludes other electronic devices capable of playing video games such as PDAs and graphing calculators . Early arcade games, home consoles, and handheld games were dedicated hardware units with the game's logic built into the electronic componentry of the hardware. Since then, most video game platforms are considered programmable, having means to read and play multiple games distributed on different types of media or formats. Physical formats include ROM cartridges , magnetic storage including magnetic-tape data storage and floppy discs , optical media formats including CD-ROM and DVDs , and flash memory cards. Furthermore digital distribution over
11424-472: The patents. Following their agreement, Atari made a home version of Pong , which was released by Christmas 1975. The success of the Odyssey and Pong , both as an arcade game and home machine, launched the video game industry. Both Baer and Bushnell have been titled "Father of Video Games" for their contributions. The term "video game" was developed to distinguish this class of electronic games that were played on some type of video display rather than on
11543-409: The platform, as directed by the game's programming. This often will include sound effects tied to the player's actions to provide audio feedback, as well as background music for the game. Some platforms support additional feedback mechanics to the player that a game can take advantage of. This is most commonly haptic technology built into the game controller, such as causing the controller to shake in
11662-399: The player interacts with the game. Specialized controllers may be used for certain genres of games, including racing wheels , light guns and dance pads . Digital cameras and motion detection can capture movements of the player as input into the game, which can, in some cases, effectively eliminate the control, and on other systems such as virtual reality, are used to enhance immersion into
11781-502: The player that can be copyrighted, but not the underlying principles of the game. Because gameplay is normally ineligible for copyright, gameplay ideas in popular games are often replicated and built upon in other games. At times, this repurposing of gameplay can be seen as beneficial and a fundamental part of how the industry has grown by building on the ideas of others. For example Doom (1993) and Grand Theft Auto III (2001) introduced gameplay that created popular new game genres,
11900-433: The player will lose one of their lives . Should they lose all their lives without gaining an extra life or "1-UP" , then the player will reach the " game over " screen. Many levels as well as the game's finale end with a type of boss character the player must defeat to continue on. In some games, intermediate points between levels will offer save points where the player can create a saved game on storage media to restart
12019-419: The player's hands to simulate a shaking earthquake occurring in game. Video games are frequently classified by a number of factors related to how one plays them. A video game, like most other forms of media, may be categorized into genres . However, unlike film or television which use visual or narrative elements, video games are generally categorized into genres based on their gameplay interaction, since this
12138-430: The player." However, emergent behavior is not limited to sophisticated games. In general, any place where event-driven instructions occur for AI in a game, emergent behavior will exist. For instance, take a racing game in which cars are programmed to avoid crashing, and they encounter an obstacle in the track: the cars might then maneuver to avoid the obstacle causing the cars behind them to slow or maneuver to accommodate
12257-594: The popularity of webcams. Webcams can also encourage remote work , enabling people to work remotely via the Internet. This usage was crucial to the survival of many businesses during the COVID-19 pandemic , when in-person office work was discouraged. Businesses, schools, and individuals have relied on video conferencing instead of spending on business travel for meetings. Moreover, the number of video conferencing cameras and software have multiplied since then due to their popularity. Webcam features and performance can vary by program , computer operating system , and also by
12376-450: The question of what are the essential factors of a video game that separate the medium from other forms of entertainment. The introduction of interactive films in the 1980s with games like Dragon's Lair , featured games with full motion video played off a form of media but only limited user interaction. This had required a means to distinguish these games from more traditional board games that happen to also use external media, such as
12495-419: The resolution went up from gradually from 320×240, to 640×480, and some now even offer 1280×720 (aka 720p ) or 1920×1080 (aka 1080p ) resolution. Despite the low cost, the resolution offered as of 2019 is impressive, with now the low-end webcams offering resolutions of 720p , mid-range webcams offering 1080p resolution, and high-end webcams offering 4K resolution at 60 fps. Various lenses are available,
12614-637: The same time. A small number of video games are zero-player games , in which the player has very limited interaction with the game itself. These are most commonly simulation games where the player may establish a starting state and then let the game proceed on its own, watching the results as a passive observer, such as with many computerized simulations of Conway's Game of Life . Most video games are intended for entertainment purposes. Different game types include: Video games can be subject to national and international content rating requirements. Like with film content ratings, video game ratings typing identify
12733-544: The scope of what was possible. Ongoing improvements in computer hardware technology have expanded what has become possible to create in video games, coupled with convergence of common hardware between console, computer, and arcade platforms to simplify the development process. Today, game developers have a number of commercial and open source tools available for use to make games, often which are across multiple platforms to support portability, or may still opt to create their own for more specialized features and direct control of
12852-605: The screen. Other early examples include Christopher Strachey 's draughts game, the Nimrod computer at the 1951 Festival of Britain ; OXO , a tic-tac-toe computer game by Alexander S. Douglas for the EDSAC in 1952; Tennis for Two , an electronic interactive game engineered by William Higinbotham in 1958; and Spacewar! , written by Massachusetts Institute of Technology students Martin Graetz, Steve Russell , and Wayne Wiitanen's on
12971-506: The short-term effects, and Nintendo helped to revitalize the industry with the release of the Nintendo Entertainment System in North America in 1985. Along with it, Nintendo established a number of core industrial practices to prevent unlicensed game development and control game distribution on their platform, methods that continue to be used by console manufacturers today. The industry remained more conservative following
13090-488: The single pixels and a resolution below 3 μm was possible. Many users do not wish the continuous exposure for which webcams were originally intended, but rather prefer privacy. Such privacy is lost when malware allow malicious hackers to activate the webcam without the user's knowledge, providing the hackers with a live video and audio feed. This is a particular concern on many laptop computers, as such cameras normally cannot be physically disabled if hijacked by such
13209-484: The target age group that the national or regional ratings board believes is appropriate for the player, ranging from all-ages, to a teenager-or-older, to mature, to the infrequent adult-only games. Most content review is based on the level of violence, both in the type of violence and how graphic it may be represented, and sexual content, but other themes such as drug and alcohol use and gambling that can influence children may also be identified. A primary identifier based on
13328-405: The term "video game" emerged around 1973. The Oxford English Dictionary cited a 10 November 1973 BusinessWeek article as the first printed use of the term. Though Bushnell believed the term came from a vending magazine review of Computer Space in 1971, a review of the major vending magazines Vending Times and Cashbox showed that the term may have come even earlier, appearing first in
13447-546: The term in an article in March 1973. In a September 1982 issue of RePlay , Adlum is credited with first naming these games as "video games": "RePlay's Eddie Adlum worked at 'Cash Box' when 'TV games' first came out. The personalities in those days were Bushnell, his sales manager Pat Karns, and a handful of other 'TV game' manufacturers like Henry Leyser and the McEwan brothers. It seemed awkward to call their products 'TV games', so borrowing
13566-503: The type of gameplay, such as action game , role playing game , or shoot 'em up , though some genres have derivations from influential works that have defined that genre, such as roguelikes from Rogue , Grand Theft Auto clones from Grand Theft Auto III , and battle royale games from the film Battle Royale . The names may shift over time as players, developers and the media come up with new terms; for example, first-person shooters were originally called "Doom clones" based on
13685-539: The use of a fixed-focus lens does not impact image sharpness to a great extent. Most models use simple, focal-free optics (fixed focus, factory-set for the usual distance from the monitor to which it is fastened to the user) or manual focus. Webcams can come with different presets and fields of view . Individual users can make use of less than 90° horizontal FOV for home offices and live streaming. Webcams with as much as 360° horizontal FOV can be used for small- to medium-sized rooms (sometimes even large rooms). Depending on
13804-430: The use of webcams for cyber-bullying . Webcam recordings of teenagers, including underage teenagers, are frequently posted on popular Web forums and imageboards such as 4chan . Webcams can be used as security cameras . Software is available to allow PC-connected cameras to watch for movement and sound, recording both when they are detected. These recordings can then be saved to the computer, e-mailed, or uploaded to
13923-562: The users' purposes, webcams in the market can display the whole room or just the general vicinity. As the bayer filter is proprietary, any webcam contains some built-in image processing , separate from compression. Digital video streams are represented by huge amounts of data, burdening its transmission (from the image sensor, where the data is continuously created) and storage alike. Most if not all cheap webcams come with built-in ASIC to do video compression in real-time. Support electronics read
14042-422: The video game industry, following the first game hardware releases and through 1983, had little structure. Video games quickly took off during the golden age of arcade video games from the late 1970s to early 1980s, but the newfound industry was mainly composed of game developers with little business experience. This led to numerous companies forming simply to create clones of popular games to try to capitalize on
14161-434: Was initially some confusion in the arcade industry over what term should be used to describe the new games. He "wrestled with descriptions of this type of game," alternating between "TV game" and "television game" but "finally woke up one day" and said, "What the hell... video game!" While many games readily fall into a clear, well-understood definition of video games, new genres and innovations in game development have raised
