    摘要： A gray balance control system for reproducing original images. An optical signal is separated into a plurality of separated color signals, gray balance conversion data for each of the colors of the separated color signals is stored in a memory circuit, and an equivalent neutral density conversion is performed on the plurality of separated color signals by converting the color signals to gray balanced color signals in accordance with the gray balance conversion data. Finally, the gray balanced color signals are converted into print signals for coloring materials.

    摘要： A ground detection means 10 for detecting the ground level of a document and a data correction means 11 for calculating correction data based on the detected ground level are provided. The ground level of the document is detected by prescanning and the correction data is calculated therefrom so that parameters of color conversion means 2, 3 are changed by the correction data. The correction data is set by approximating the detected ground level with a linear function. As a result of the above construction, the correction data is generated easily to thereby remove ground fog and exclude back-side images of the document. In addition, if the ground level is detected by a lightness signal L* and corrected by the lightness signal L* or a color-separated signal BGR, the correction can be achieved by correcting the parameters of a matrix that converts the color-separated signals B, G, R to a system value (L*a*b*) signal.
