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