Abstract
PURPOSE:To contrive to reduce the adjusting time by arranging plural circular light sensors on a television display pattern and adjusting the adjustment variable resistor depending on the position deviation information of a raster with respect to the center of the light sensor obtained by an output signal of the light sensor caused by the measured pattern. CONSTITUTION:A test signal generating circuit 9 is controlled by a microcomputer 8 and its output signal becomes a measured pattern via a D/A converter 10 and a video signal processing circuit 11, 15. Sets of pickups 1 are arranged on the display pattern of the screen 2 and its output signal is fed to an A/D converter 7 via an amplifier 4, a sample-and-hold circuit 5, an analog switch 6, and the measured data converted into a digital signal is fed to the microcomputer 8. The microcomputer 8 calculates the deviations x, y of the measured data with respect to the three primary colors, decomposes them into a component corresponding to each adjusting variable resistor, the formed registration adjusting component is fed to a motor controller 12 to drive the adjusting variable resistor 15 via a drive circuit 13 and a pulse motor 14.
