ABSTRACT:
A television camera is provided with a color resolving optical system for color resolution and for forming a plurality of optical paths, the color resolving optical system having at least one dichroic film, a plurality of image pick-up tubes disposed on the optical paths for receiving the image of an object to be photographed, and an illuminating device emitting a plurality of illuminating lights of a predetermined wavelength range and provided with an adjuster for adjusting the quantity of light of at least one of said illuminating lights. The wavelength band width of said illuminating lights is narrower than the wavelength band width color-resolved by the color resolving optical system and/or the positions at which said illuminating lights are emitted differ from one another, whereby color shading of the image pick-up tubes is eliminated.
