摘要： Exposure areas in a calibration original are automatically found by reference to a registration mark having a predetermined dimensional orientation relative to the exposure areas. A scanner produces image signals representative of both the exposure areas and the registration mark. A pattern recognition module employs edge detection to distinguish image signals corresponding to the registration mark. Two-dimensional Cartesian coordinates are then extracted from the registration mark and used to further distinguish image signals corresponding to the exposure areas, thereby locating exposure areas although the original may not be properly aligned in the scanner. A preferred registration mark is a pair of orthogonal, intersecting guide bars. By further defining the nominal length of the guide bars, the size of the mark can be established and the exposure areas can be located despite dimensional changes due to magnification error in the scanner.

摘要： Color image reproduction apparatus includes a video monitor for displaying a reproduced image (a soft copy) to appear on any of a variety of image-receptive output media (reversal film or negative film to print material or reversal film to print material) in which color of the reproduced image may vary from one type of output medium to another. A computer-based workstation, having a series of look-up tables for transforming imaging data to a variety of monitor-dependent RGB color spaces, enables the video monitor to show a series of displays of the reproduced image with each version of the reproduced image being visually matched to the reproduced image as it would appear on a particular one of the image-receptive output media.
