Claim One:
1. A method of redistributing an N-primary color input signal (IS) having a particular number≧4 (N) of input components (I 1 ,. .. , IN) into N-primary color output signal (OS) having the particular number (N) of output components (P 1 ,. .. , PN) under a constraint (CON 2 ), the method comprises: defining (MPRC) three functions (F 1 , F 2 , F 3 ) representing three (P 1 , P 2 , P 3 ) of the output components (P 1 ,. .. , PN) as a function of the remaining N-3 output components (P 4 ,. .. , PN), substituting (MPRC) the values of the input components (I 1 ,. .. , IN) into the three functions (F 1 , F 2 , F 3 ) to determine unknown coefficients (P 1 ′, P 2 ′, P 3 ′) of the three functions (F 1 , F 2 , F 3 ), and determining (MPRC) optimal values of the output components (P 1 ,. .. , PN) by applying the constraint (CON 2 ) to the three functions (F 1 , F 2 , F 3 ).
