ABSTRACT OF THE DISCLOSURE Apparatus is provided for optimum adjustment of a television picture at all ambient light levels and power supply loading conditions with a minimum of manual adjust- ments. A light-responsive element is included to control the gain of luminance and chrominance amplifiers in prop- ortioned ratio and to adjust electrical black level to correspond to optical black level. Power supply sensing is included to reduce picture drive to prevent overload con- ditions while maintaining black level constant. Additional picture sensing reduces drive current on scense of high average brightness under low ambient light conditions.
