MEASUREMENT OF CONVERGENCE AND METHOD THEREOF USING CHARGE COUPLED DEVICE

摘要

The R.G.B. positional coordinates analyzing apparatus through a monochrome CCD(Charge Coupled Device) camera in adjusting a CRT(Cathode-Ray Tube) convergence is constructed in a CRT convergence adjuster by the characteristic that a signalling unit(30) for supplying a pattern(R.G.B. signal) necessary for the adjustment is connected to a CRT(40) which is an object for its adjustment, and that a monochrome CCD camera(10) for receiving information concerned with the patter displayed on the CRT(40) screen is connected to a processor(20) which performs an instrumentation, an analysis and a decision.
