Abstract
A high resolution solid-state color imaging apparatus having two-dimensionally disposed photoelectric sensors are arranged in rows and columns each having a color spectral responsivity characteristic such as by employing color filters. Each of the photoelectric sensors is scanned so as to obtain an intensity signal with respect to each row of each field, and wherein scanning of each field is for the same number of rows as that of each frame. Intensity signals are obtained only by the scanned output of each row. Additional intensity signals equal to half the number of said first mentioned intensity signals are obtained by a 2:1 subsampling of bandwidth-restricted signals by a filter along the vertical temporal frequency, thereby realizing high vertical resolution by the photoelectric image sensors of conventional row numbers and having compatibility with a conventional NTSC system and, furthermore, eliminating aliasing distortion.
