Improved Line Sequential Color Difference System for Single-chip Color Camera

Abstract

An improved line sequential color difference system for signal-chip color camera has been developed. It ensured a high quality color video signal. By using this system, not only a large luminance signal but also a large color special modulation rate are obtained. Color error appearing on a vetical color edge inherent in a line sequential color difference system has been reduced.
Applying this system to CPD image sensor, 46 dB luminance S/N ratio and 45 dB of R-Y color difference S/N ratio are obtained under 300 Lx and F 1. 4 conditions.
