ABSTRACT:
In a color television camera of a construction wherein a light beam is separated into a plurality of beams of necessary wavelength ranges by a color separating optical system and these beams are caused to impinge on the light receiving surfaces of respective pick-up tubes, color filter means is provided in the path followed by the light beam before entering any of the color separation surfaces of the color separating optical system, which filter means continuously varies its transmission factor for the light of a preselected one of the plurality of necessary wavelength ranges from one end thereof to the other, whereby the color shading which would otherwise take place on the image display surface of a television receiver may be optically prevented.
