Method and apparatus for converting original image data to density data for forming an image on photosensitive material and for displaying an image on a monitor

摘要

An image processing method in which an image of an original is read by an image input device, the read image data is converted to density data used when printing onto a photosensitive material, and an image is obtained on the photosensitive by digital exposure, wherein, when the image data is converted to the density data used when printing onto the photosensitive material, the image data is corrected on the basis of parameters determined by combinations of print finish characteristics, including at least image input device characteristics, which affect a print image when the image of the original is printed on the photosensitive material by an analogue exposure system. On the basis of the above parameters, the density data is obtained while the image data is corrected. For this reason, an image finish print in the digital exposure system can obtain an image quality which is equal to that of a finish print in an analogue exposure system. Additionally, data for monitor display is generated so that the gradation and color tone of the image displayed on the monitor coincide with the gradation and color tone of the image printed on the photosensitive material.
