Abstract

See full text

A color camera apparatus comprises an image pickup element having a stripe/mosaic type color filter and photo-electrically converting an arriving optical image so as to obtain at least a signal including a brightness component and a color component multiplexed with each other. And, the apparatus comprises an A/D converter for digitizing above multiplexed signal, and a brightness signal processing circuit which separates the brightness component from the multiplexed signal and carries out an aperture correction by means of a delay element having a delay amount corresponding to two horizontal scanning period. And further, the apparatus comprises a color signal processing circuit which separates the color component from the multiplexed signal so as to obtain two line-sequential color difference components through a predetermined arithmetic procedure. And, the color signal processing circuit not only carries out a circular-type noise removal processing operation by means of the delay element having the delay amount corresponding to two horizontal scanning periods, but carries out a rearrangement of said line-sequential color difference components by use of the same delay line.
