  • Patent number: 4249197
    Abstract: A television camera adjustment by means of a monitor picture is effected by forming a window area therein by means of which the camera operator directs the camera to a scene, the window area lines being used as an indication that an optimal adjustment has been achieved or as an indication for the operator that he must perform an adjustment procedure into one or into the other direction because it is not possible to obtain the optimal situation by means of surpassing a control range. With a color television camera the procedure can be used for a white balance adjustment combined in an advantageous manner with a black level adjustment.
