Abstract
A color image pickup apparatus using a single-plate type solid-state image sensor is arranged to obtain a signal of an excellent color separation characteristic. An object image is formed on the photoelectric conversion part of the image sensor with color filters of different colors disposed on each of the picture elements of the image sensor. A signal outputted from the solid-state image sensor is converted into a digital signal by an A/D converter. The digital signal is taken in by a signal processing circuit to separate chrominance signals superposed on a luminance signal. At that time, signals for primary color components are formed by carrying out a matrix computing process by using coefficients obtained from the image pickup output of the solid-state image sensor.
