IMAGE POSITION DETECTOR, IMAGE POSITION DETECTION METHOD AND COLOR-SLURRING DETECTOR FOR COLOR CATHODE-RAY TUBE, AND METHOD FOR DETECTING COLOR SLURRING OF COLOR CATHODE-RAY TUBE

摘要

PROBLEM TO BE SOLVED: To accurately detect the position of an image. SOLUTION: A CCD camera 4 picks up a measurement pattern 3 displayed on a color cathode-ray tube 2 to detect luminance data and substitutes luminance data to positions other than the position of an imaging device and the accurate position of the image can be detected from the luminance data.
