摘要:
This invention discloses a television camera provided with a test pattern projecting device which is capable of forming an image of a test pattern of a desired color temperature onto the television tube. In said test pattern projecting device, an image of test pattern with adjustable color temperature is obtained by spatially dividing the test pattern illuminating light beam of a test pattern projecting light beam into plural color component beams, independently regulating the strength of said divided component beams and again uniting said divided component beams.
