Solid-state color image sensing device

摘要

The disclosed solid-state color image sensing device has a color mosaic filter adapted to correspond to each of the picture elements of a solid-state image sensing element and is arranged to obtain a color signal from a difference signal corresponding to a difference between the direct output signal of the solid-state image sensing element and another output signal obtained through one preceding horizontal scanning period. The device provides a signal producing circuit which produces an inversion control signal arranged to control the periodic inversion of the difference signal determined by the color arrangement of the color mosaic filter and an inversion processing circuit which uniformalizes the polarity of a predetermined color signal in response to the inversion control signal. The above stated color signal is obtained from the low frequency zone component of the output signal of the inversion processing circuit.
