DEVICE FOR REDUCING COLOR MOIRE OF SINGLE CHIP COLOR CAMERA

摘要

PURPOSE: A color moire reducing device for a single chip color camera is provided to prevent color signals by moire from being supplied to a color temperature detection part and carry out the color suppress of an edge signal, gain control for auto white balance in a gain control part, thereby simplifying the circuit arrangement. CONSTITUTION: A color moire reducing device for a single chip color camera includes a first multiplexer(430) for controlling RGB signals output to a color temperature detection part(440) and a gain control part(460) from an RGB matrix circuit part according to an edge signal(S1) output from an edge detection part(360), and a second multiplexer(450) for alternatively outputting a color gain control signal output from a lookup table or R'G'B' signals output from the color temperature detection part according to a color gain control signal(S2) output from the lookup table.
