Title:
N個の原色入力信号をN個の原色出力信号に再分配する方法、システム及びコンピュータプログラム
Document Type and Number:
Japanese Patent JP2008538614
Kind Code:
A
Abstract:
A method of redistributing an N-primary color input signal (IS) having a particular number≧4 (N) of input components (I1, . . . , IN) into N-primary color output signal (OS) having the particular number (N) of output components (P1, . . . , PN) under a constraint (CON2). The method comprises defining (MPRC) three functions (F1, F2, F3) representing three (P1, P2, P3) of the output components (P1, . . . , PN) as a function of the remaining N-3 output components (P4, . . . , PN). Substituting (MPRC) the values of the input components (I1, . . . , IN) into the three functions (F1, F2, F3) to determine unknown coefficients (P1′, P2′, P3′) of the three functions (F1, F2, F3). And, determining (MPRC) optimal values of the output components (P1, . . . , PN) by applying the constraint (CON2) to the three functions (F1, F2, F3).
