Display and Image Processors

Advertisement

The i-Chips Display and Image Processors are highly integrated devices that allow you to convert an image from any source—video or graphics—to drive a digital display system such as an LCD panel or to convert it to a different video standard. Among the supported image processing tasks are: resolution conversion or scaling; frame rate conversion; video de-interlacing; and color space conversion.

Image scaling is a digital processing function required to generate the pixel resolution for the display system. The i-Chips processor calculates each output pixel to be displayed from its corresponding area of the input image.

Frame rate conversion is a critical function required to produce a signal that is compatible with the digital display device, and most often different from the video source. This is accomplished by real-time image processing to guarantee smooth motion in the output image.

Video de-interlacing is required to convert the video signal from interlaced to a progressive-scan format. The i-Chips processors use an advanced motion-adaptive method to precisely calculate each output pixel to avoid image artifacts.

The i-Chips Processors support all Standard Definition and HDTV formats, 8-bit and 10-bit processing. They are used in a applications such as LCD projectors, flat-panel displays, video walls, plasma display panels, control systems, and products for the home theater, broadcast, medical and military markets.
