ABSTRACT:
A 1-chip color video camera which provides a frequency characteristic that exhibits relatively little attenuation up to a high frequency range for a (green) signal and has a highest degree of contribution to brightness, and hence provides high resolution. The 1-chip color video camera has a color separation circuit for processing signals obtained from a solid-state image sensor wherein primary color filters of R(red), G and B(blue) are arranged mosaic-wise for respective pixels. Color signal components at a central portion of a pixel block consisting of four pixels of two rows by two columns on the solid-state image sensor are generated by interpolating color signal components of a plurality of neighboring pixels.
