ABSTRACT:
An apparatus for automatically establishing a color balance for a color television monitor includes a sensor device which is separably attached to the screen of the monitor to detect the brightness of the ambient light. The ambient light brightness detected when no image is displayed is used to compensate reference data for establishing a color balance of the color signals independent of the ambient light.
