Abstract

First characteristic values of a reference film is stored in a first characteristic value memory, whereas second characteristic values of each type of recording media of the originals is stored in a second characteristic value memory, to produce a gradation balance conversion table for each color from the first and second characteristic values. Image data of an original is converted according to the gradation balance conversion tables, so as to make the color balance proper in all density ranges from highlight through shadow points, even if the original image is under-exposed or over-exposed. The gradation balance converted image data is converted through an image data conversion device into recording data to record a reproduced image as a hard copy of the original.
