ABSTRACT:
Apparatus for automatically and/or manually controlling setup of a device such as a color television camera. The system includes a closed loop automatic setup system which provides at least one setup control signal to the camera and, during a specific automatic setup operation, responds to at least one video signal provided by the camera to automatically adjust the level of the setup control signal. A manual control is also provided which permits manual variation of the level established by the auto setup system. In addition, apparatus is included for disabling the manual control during the automatic setup operation so that at that time the setting of the manual control does not influence the level of the setup control signal. The apparatus is also operable in fully automatic and fully manual modes.
