Method and system in video image hard copy reproduction

摘要: A system and method for the accurate reproduction of gray scale a video monitor screen includes, in one embodiment, an electronic camera having internal receiver with CRT screen. test pattern is displayed on measured using photometer. also screen, photographed film. The developed film photoelectric densitometer results are entered into computer memory look-up table compared, by tone-by-tone basis, ideal luminance value each tone based photometer measurements. set corrections obtained measurements corrected to all tones available system. Those compensating used adjust luminance, pixel-by-pixel camera, so that compensated produce which reproduces
