Abstract
Abstract A solid state color television camera which handles a composite color video signal consisting of interlaced full field informations. The color camera employs a charge coupled device the picture elements of which are selected to be in a shifted relation by 1/2 of alignment pitch in the vertical direction between odd and even fields, and in which a color filter to be disposed between an object and the charge coupled device is arranged in its construction such that the charge coupled device is capable of supplying output video signals of the same color components between odd and even fields.
