ABSTRACT:
An analog-signal gate circuit or sample-hold circuit is employed for processing a dot-sequential video signal derived from a solid state imaging device such as CCD imager. By changing a signal width, gain control operation is achieved, and phase shifting operation of the video signal is done by shifting an aperture center of the dot-sequential video signal. This system may be applied to a color signal conversion system wherein a dot-sequential color signal is converted directly to an NTSC color television signal. Further, white balance control for a solid state color television camera is another application of this system.
