Abstract

PURPOSE: To make automatic adjustments without requiring the eye appreciation of an operator by forming a white balance requlator of a picture pattern generator, control system unit, screen voltage regulator, and driving voltage regulator.
CONSTITUTION: On the display screen of color Braun tube 10, a fixed picture pattern is displayed by picture pattern generator 33 and control system unit 26 processes output signals, equivalent to three primary colors, obtained by photoelectric detectors 21 and 22 arranged opposite on the display screen of Braun tube 10 to generate signals which vary in a fixed sequence the screen voltages equivalent to respective colors; and screen voltage regulator 31 equalizes each luminescence intensity to a fixed value by the command of control system unit 26 and driving voltage regulator 32 processes the output signals of detectors 21 and 22 to adjust drive voltage gains equivalent to respective colors by the command of control system unit 26, thereby equalizing luminance levels of the three primary colors of fixed video signal values to fixed values.
