摘要: A technique for calibrating a cathode ray tube multiformat camera and video monitor. image is corrected on pixel-by-pixel basis gray scale produced photosensitive medium, such as film, monitor with uniform quantization in perceived lightness (i.e., or shade varies linearly digital code value). Consequently, there no loss of small-signal strong-signal structures (detail), all the information recorded film clearly displayed
