Abstract: A color image pickup device comprises a lenticular lens disposed in front of and between the image forming screen of a pickup tube and an object to be televised. A color-resolving stripe filter is disposed in front of the lenticular lens. The transverse width of one group of filter elements of the stripe filter is selected to be twice the pitch of each lens element of the lenticular lens. Furthermore, the positions of the lenticular lens and of the stripe filter relative to the image forming screen are selected so that the optical image of the filter is formed on the image forming screen with a magnification ratio of 1 : 1.
