Monitor system for image printer

摘要

A monitor adjusting system facilitates image adjusting procedures such as color or density correction. Prior to printing an image onto photosensitive paper, the exposure settings are selected so that the printed image on the print paper will have proper colors and densities. Initial adjustments are made to the exposure setting based on the actual images being developed. To check the correctness of the changes in exposure setting for the actual images, the operator inserts a color calibration (reference) film strip which is read and displayed by the system. The film strip will display two images: (1) a reference scene of a human subject or a landscape and (2) either a density chart or a color chart. The images are used as indicators of the correctness of the adjustments made. Using the color chart separates out the effects of exposure on individual colors, while the landscape or human image simultaneously displays the effected exposure settings on a great number of color components in a complicated mixed pattern. This provides two sets and types of indicators to facilitate the correction of exposure to the point that even inexperienced operators can make corrections with relative ease.
