Abstract
In a solid state television camera, there are disposed a first color filter including primary color elements and complementary color elements therefor aligned alternately in the horizontal direction and a second color filter including second primary color elements and complementary color elements therefor aligned in the same manner onto sensing units of a charge coupled image sensor alternately relative to odd and even lines. The positions of respective sensing points of the sensing units are so selected that vectors of side band components of signals obtained by adding signals from successive odd and even lines are symmetrical with respect to the detecting axis of a phase detector when panchromatic light is projected on the image sensor through the first and second color filters.
