Abstract
PURPOSE: To realize a high-accuracy and automatic adjustment by giving adjustment to the adjusting variable register by the chrominance signal obtained by making the three photo detectors for the red, green and blue colors touch the surface of the Braun tube.
CONSTITUTION: The low-luminance white signal is generated from white signal generator 8 by the control of microcomputer 6 and then applied to color TV picture receiver 1. Photo detectors 4a∼4c for detection of the red, green and blue colors have a contact to the surface of Braun tube 3 of receiver 1, and each output signal of these phoment to the background of controlled variable resistors 2a∼2e. After this, the driving volume is adjusted in a high luminance to complete the balance adjustment.
