Abstract

PURPOSE: To improve adjustment efficiency by providing the 1st photoelectric detector for picture pattern display detection at the center part of color CRT and the 2nd photoelectric detector for picture pattern display photo-detection at the circumference and by adjusting the CRT on the basis of the detection results.
CONSTITUTION: Picture pattern generator 8 forms a green monochromatic scene and deflecting coil 2 is moved by deflecting-coil position adjusting mechanism 15 to obtain a mislanding state. A shift in a fluorescent part is detected by 2nd photoelectric detectors 10 and 11 and inputted to arithmetic circuit 14 via decision circuit 12 before being stored in memory 13. Monochromatic images in red and blue are processed in the same way and the arithemtic results of circuit 14 are fed back to colorimetric purity adjusting mechanism 17 for the adjustment of a purifying magnet. Then, coil 2 is returned to its original point. Next, generator 8 forms a white dot pattern, the 1st photoelectric detector 9 detects respective shifts in color display position, and processing results of circuit 12, memory 13 and circuit 14 are fed back to static convergence adjusting mechanism 16, thereby making adjustments of static convergency yoke 3.
