Abstract
Abstract A solid state color imaging apparatus is constructed by combining a solid state image sensor having a plurality of photoelectric elements disposed in two dimensional rows with parallel stripe type color filters having repetition of three or four color-filter-element stripes put in front of the image sensor. The device is free from hitherto required severe registration between the filter and the solid state image sensor. This is accomplished by selecting relative spatial phase relation between the filtered picture elements of horizontal scanning lines in a manner that the phase relation changes for every horizontal lines which are scanned in sequence. The demodulation of the chrominance signal to produce NTSC signal is made by using synchronous demodulator.
