ABSTRACT:
A device and method provides high-speed processing in a color television camera without color mixing and achieves a color balance. The device comprises a color filter for color separating the light from the object being photographed, a solid state imaging element that forms an image from the light separated by the color filter, and with which control of charge accumulation is possible; and an accumulation time regulating device that sets the charge accumulation time of the solid state imaging element so as to avoid the color mixing interval during which color boundaries of the color filter are passing over the solid state imaging element. Charge is only accumulated during intervals other than the color mixing interval. Color balance of a field-sequential color television camera can be set without relying on a signal executing circuit.
