Abstract

PURPOSE: To obtain a television camera with an incorporated test pattern projector which can obtain a test pattern of desirable color temperature, by making it possible to adjust the quantity of a light flux by forming several color component light fluxes.
CONSTITUTION: Test pattern projective lens system Z provided into object lens system X of the television camera forms the image of transmissive type test chart 2' on pickup tubes 3R, 3G and 3B for red, green and blue region light fluxes by light source 1'. Light source 1' consists of light sources 21R, 21G and 21B which can make electric adjustments of their quantities of light separately, color filters 22R, 22G and 22B, and glass fibers 23 to 23". Light fluxes from light sources 21R, 21G and 21B are mixed by tube 24 and radiated by diffusion to be used for the pickup of test chart 2'. Since light sources 21R, 21G and 21B can adjust their light fluxes independently, their color temperatures can be adjusted freely.
