SPEEDUP SYSTEM OF COLOR CONVERSION IN MULTIPLE PRIMARY COLORS DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress an increase in time for color conversion based on a linear programming of a multiple primary colors display device and to reduce it almost equal to a time for color conversion of a simple matrix method without increasing power consumption. SOLUTION: The speedup system of color conversion in a multiple primary colors display device is provided with: a first processing means for converting XYZ image data according to the linear programming, establishing a classification model by using its result with non-base (nCn-3*2n-3kind) out of a base/non-base combination as learning data, and generating a 3*3 inverse matrix of a corresponding base part as a 3*3 color conversion matrix; and a second processing means for obtaining a combination of optimal non-base from the inputted XYZ image by using the established classification model and the inverse matrix and performing calculation by a matrix corresponding to the combination. Thus, the system performs color conversion at high speed. COPYRIGHT: (C)2006,JPO&NCIPI
