Title:
COLOR CORRECTION SYSTEM FOR PICTURE FORMING DEVICE
Document Type and Number:
Japanese Patent JPH02119465
Kind Code:
A
Abstract:
PURPOSE:To improve the processing speed of a picture data by synthesizing outputs of a conversion table corresponding to each color separation signal so as to generate a recording signal. CONSTITUTION:A conversion table 4 corresponding to each color separation signal is provided, outputs of the conversion table 4 relating to each color separation signal are synthesized by a synthesis circuit 5 to generate a recording signal. Thus, a desired conversion data is obtained from the addition/subtraction processing of the output by having only to store the value after the calculation of a prescribed parameter in the conversion table 4. Thus, the processing time can be shortened. Moreover, plural conversion tables 4 are provided corresponding to each color separation signal to obtain conversion data depending on the product of sums of other signals and other plural color separation signals.
