ABSTRACT:
A color image sensing apparatus includes a solid-state image sensing element having a color separation filter, a circuit for extracting a color difference signal from an output of the solid-state image sensing element, first and second color difference signals which are alternately extracted for every scanning line, and a delay-type line memory for storing an output signal from the color difference signal extraction circuit and for reading out a stored signal after one horizontal scanning period. The line memory is a first-in first-out type digital memory having a delay time corresponding to one horizontal scanning period. A circuit is provided for outputting the first and second color difference signals for every one horizontal scanning line, based on the output signal from the color difference signal extraction circuit and the output signal from the line memory. In this manner, the first and second color difference signals can be output not alternately, but simultaneously for every one horizontal scanning line. The delay time of the line memory is varied in accordance with the number of pixels in the solid-state image sensing element. Frame memories can be used to store the output signal of the color difference signal extraction circuit and a wide-band luminance signal which is extracted from the output of the solid-state image sensing element.
