ABSTRACT:
A solid state imaging apparatus includes two-dimensional frequency process which is applied to an output signal from each pixel of a progressive scan-type CCD. The CCD has an an arrangement of color separation filters without making carriers in the horizontal and vertical directions of the two-dimensional frequency to obtain chrominance signals with less moire in the horizontal and vertical directions of the two-dimensional frequency. A luminance signal with less moire in the horizontal and vertical directions of the two-dimensional frequency can be obtained by interpolating with the ratio of a chrominance signal with less moire.
