A digital video signal post-processor for color image sensors

A description is given of a digital-video-signal postprocessing chip (DSPP) developed for use with one-chip color video image sensors. The chip improves the image quality of reconstructed RGB data by performing black-level adjustment, color correction matrixing, gamma correction, and edge enhancement. It contains 115000 transistors in a 11.5 mm×11.2 mm die area and was designed using a silicon compiler in a 2-μm die area and was designed using a silicon compiler in a 2-μm CMOS process. It can be used in NTSC, CCIR 601, and PAL/SECAM video systems
