1. In a color television camera having a target structure, means for producing an electron beam which scans the target structure in a line scanning direction, and means for projecting onto the target structure an image of an object in the field of view of the camera;

  • said target structure comprising a first group of photoconductive elements for converting light projected thereon into an electrical output when scanned by said electron beam and being arrayed in lines extending in said line scanning direction and in rows at substantial angles to said direction, a second group of photoconductive elements for converting light projected thereon into an electrical output when scanned by said electron beam and also being arrayed in lines extending in said line scanning direction and in rows at substantial angles to said direction with said lines of the photoconductive elements of said second group being alternated with said lines of the photoconductive elements of said first group, color filter elements each corresponding to a respective one of said photoconductive elements and being disposed between the latter and the object for forming on the respective photoconductive elements corresponding color components of said image projected on the target structure, first electrodes extending generally along said lines of photoconductive elements and being connected with said first group and said second group, respectively, of said photoconductive elements for picking up a color video signal from said photoconductive elements in response to the successive scanning thereof by said electron beam, and second electrodes arranged generally in the direction of said rows of photoconductive elements for producing an index signal.
