Signal processing circuit for a solid-state image pickup device

DETAILED DESCRIPTION It is an object of the present invention to provide a signal processing circuit in the multi-plate type solid state color image pickup device allowing to perform high-quality image pickup of a solid-state image pickup device including analog-to-digital converting means for digitizing image pickup output signals at a clock rate equal to a sampling rate fs, said image pickup output signals being read at the sampling rate fs from the solid-state image sensor for green-color image pickup and the solid-state image sensors for red-color and blue-color image pickup of the image pickup section, that are arrayed with a spatial shifting equal to one half the pixel pitch from each other; a processing circuit for processing the digital output signals of the analog-to digital converting means, and color encoder means supplied with output signals of said processing circuit output signal having superior MTF characteristics and containing lesser amounts of aliasing components.
It is another object of the present invention to provide a color image pickup device in which a digital interface conforming to the standards for the digital interface related equipment is loaded on the solid state image pickup device the image pickup section of which includes solid state image sensors, each having a discrete pixel array, such as CCD image sensors, to allow to produce high-quality digital composite video signals having satisfactory MTF characteristics and containing lesser amounts of aliasing components.
It is a further object of the present invention to provide a signal processing circuit and producing digital composite video signals; whereby the high-quality digital composite video signals having superior MTF characteristics and containing lesser amounts of aliasing components may be produced.
