ABSTRACT:
A color signal processing apparatus for processing signals from a color signal-plate sensor having an offset sampling filter array and obtaining a luminance signal and a plurality of color signals, wherein a vertical and/or horizontal low-pass filter is used in common for both the luminance signal and the plurality of color signals. The low-pass filter preferably includes a shift register having a stage number equal to the number of pixels of the sensor in the horizontal direction, and a switch for alternately selecting a zero signal and data, and the vertical low-pass filtering is performed digitally.
