Abstract
An image pickup apparatus including an image pickup device to convert an image pickup light from an object to be photographed into an electric signal, a signal processing circuit to obtain a luminance component signal and color difference component signals on the basis of an output of the image pickup device and a color separation matrix circuit to obtain chrominance signals from the luminance component signal and the color difference component signals. Matrix coefficients in the color separation matrix circuit are determined so as to obtain the optimum chrominance signals when the luminance component signal and the color difference component signals obtained by photographing an object of each color are color separated.
