LF2272

LF2272 DEVICES INCORPORATED DEVICES INCORPORATED Colorspace Converter/ Corrector (3 x 12-bits) DESCRIPTION The LF2272 is a high-speed digital colorspace converter/corrector consisting of three simultaneous 12-bit input and output channels for functionality up to 64 Giga (236) colors. Some of the applications the LF2272 can be used for include phosphor colorimetry correction, image capturing and manipulation, composite color encoding/decoding, color matching, and composite color standards conversion/transcoding. The 3 x 3 matrix multiplier (triple dot product) allows users to easily perform three-dimensional perspective translations or video format conversions at real-time video rates. By using the LF2272, conversions can be made from the RGB (color component) format to the YIQ (quadrature encoded chrominance) or YUV (color difference) formats and vice versa (YIQ or YUV to RGB). Differing signal formats in each stage of a system can be disregarded. For example, using an LF2272 at each format interface allows each stage of a system to operate on the data while in the appropriate format.
