Abstract
A view-finder is used for a television camera which has an image pick-up device for picking up an image of an object responsive to incident light from the object. The television camera comprises an optical system for diverging a part of a light advancing from the object to the image pick-up device. The view-finder comprises a monochrome television picture receiving device which is supplied with an output signal of the image pick-up device and displays a monochrome picture image, and an optical system for composing the picture image of the monochrome television picture receiving device and an optical color image formed by the light diverged by the diverging optical system to form an optical image to be observed.
