Abstract

다수의 카메라로 브라운관을 촬영하고, 그 다수의 영상신호를 아날로그 멀키플렉서에 의해 하나를 선택하고, 그 선택된 신호를 A/D 변환부로 변환하여 변환처리부에서 처리하여 이진영상을 만들고, 이 이진영상을 모니터로 보거나 영상저장부에 저장하고, 동시에 그 이진영상을 프로젝션 처리하여 그 결과를 프로젝션 저장부에 저장하여 색순도 측정프로그램을 실행하면서 상기 영상저장부와 상기 프로젝션 저장부의 데이터를 사용하여 색순도를 판단한다.Photograph the CRT with a plurality of cameras, select one of the plurality of video signals by an analog mulkyplexer, convert the selected signal into an A / D converter, and process it in a conversion processor to create a binary image. View the image on the monitor or the image storage unit, and simultaneously process the binary image, store the result in the projection storage unit, and execute the color purity measurement program to determine the color purity using the data of the image storage unit and the projection storage unit. do.
