Imageon (previously ATI Imageon ) was a series of media coprocessors and mobile chipsets produced by ATI (later AMD ) in 2002–2008, providing graphics acceleration and other multimedia features for handheld devices such as mobile phones and Personal Digital Assistants (PDAs). AMD later sold the Imageon mobile handheld graphics division to Qualcomm in 2009, where it was used exclusively inside their Snapdragon SoC processors under the Adreno brand name.
27-489: Many of the Imageon processors were simply camera, multimedia, and display ISP 's. Most only provided basic acceleration for 2D graphics, photo, video and audio encoding and decoding. However, they still played an essential role in enabling broad adoption of multimedia (camera and video) capabilities in featurephones, having shipped over 100 million Imageon processors by the start of 2006, and 200 million by early 2007. Since few of

To get color into the picture, they are covered with different color filters: red , green and blue ( RGB ) according to the pattern designated by the Bayer filter . As each photodiode records the color information for exactly one pixel of

The Imageon Z430 was incorporated into the Qualcomm MSM7x27 and QSD8x50 series of processors, being rebranded as the Adreno 200. The Z460 IP was licensed by STMicroelectronics (later ST-NXP Wireless ) in their ARM11 STn8820 ' Nomadik ' SoC processor in Feb 2008, but as of 2023 no products implementing this SoC have been identified. Following negotiations in June 2008,
243-639: The Imageon 2200, 2240, 2250, 2260, 2262, and later, the 2282, and 2182. These processors were used in numerous popular Motorola feature-phones, such as the Motorola Razr V3 Announced in January 2004, the Imageon 2300 introduced full 3D hardware acceleration (100M-pix/sec), in addition to 2MP camera support, and multimedia (MPEG4) playback. Having full hardware 3D support enabled OpenGL ES 1.0 and JSR184 gaming on mobile devices via software engines such as Micro3D by Mascot Capsule. These chips were used in

In digital photography its effect is often visible as random spots of obviously wrong color in an otherwise smoothly-colored area. Noise increases with temperature and exposure times. When higher ISO settings are chosen the electronic signal in the image sensor is amplified, which at
405-467: The color and brightness data of a given pixel, compares them with the data from neighboring pixels, and then uses a demosaicing algorithm to produce an appropriate color and brightness value for the pixel. The image processor also assesses the whole picture to guess at the correct distribution of contrast . By adjusting the gamma value (heightening or lowering the contrast range of an image's mid-tones), subtle tonal gradations, such as in human skin or
432-855: The early Imageon models offered full 3D hardware acceleration, ATI partnered with various middleware companies to offer software 3D rendering capabilities instead, such as the X-Forge 3D SDK produced by FatHammer, as used on the Symbian platform, and on the Tapwave Zodiac. In 2006, ATI acquired BitBoys , adding additional talent and experience with vector graphics to their mobile and handheld graphics team. After AMD 's acquisition of ATI in 2006, AMD licensed their mobile graphics technology to Qualcomm in April 2007 who integrated it into their Snapdragon processor family under their Adreno brand name. AMD subsequently sold off
459-426: The ever-higher pixel count in image sensors, the image processor's speed becomes more critical: photographers don't want to wait for the camera's image processor to complete its job before they can carry on shooting - they don't even want to notice some processing is going on inside the camera. Therefore, image processors must be optimised to cope with more data in the same or even a shorter period of time. libcamera
486-405: The first Imageon product in the line featuring Digital Video Broadcasting - Handheld ( DVB-H ) signal receiving support, allowing handhelds devices to receive digital broadcast TV (DVB-H) signals and enables watching TV programs on these devices, the chipset includes tuner , demodulator , decoder, and a full software stack. In 2008 AMD launched several additional non-3D multimedia processors under
513-424: The image, without an image processor there would be a green pixel next to each red and blue pixel. This process, however, is quite complex, and involves a number of different operations. Its quality depends largely on the effectiveness of the algorithms applied to the raw data coming from the sensor. The mathematically manipulated data becomes the recorded photo file. As stated above, the image processor evaluates
540-577: The later NovaThor processors from ST-Ericsson instead opted to use the Mali graphics core. In 2009 AMD sold their entire handheld graphics division to Qualcomm for $ 65 million, transferring all Imageon assets, IP and employees to Qualcomm. As of 2021, Qualcomm continues to produce mobile SoC 's with graphics capabilities branded under the Adreno name. Image processor An image processor , also known as an image processing engine , image processing unit ( IPU ), or image signal processor ( ISP ),
567-456: The mobile handheld graphics division to Qualcomm in 2009 for $ 65M following an earlier sale of the Xilleon branch to Broadcom . AMD retained the Imageon name and provided support for existing customers, although no future Imageon products were introduced. However, as a result of company restructuring, AMD divested the handheld chipset business starting from the second quarter of 2008, thus the line

This can be quite a challenge, as the image may contain areas with fine textures which, if treated as noise, may lose some of their definition. As the color and brightness values for each pixel are interpolated some image sharpening
