ABSTRACT:
A method of converting a three-primary input color signal (IS) comprising three input components (R, G, B) per input sample into an N-primary color drive signal (DS) comprising N≧4 drive components (D1, . . . , DN) per output sample for driving N sub-pixels (SP1, . . . , SPN) of a color additive display. The N sub-pixels (SP1, . . . , SPN) have N primary colors. The method comprises adding (10), to three equations defining a relation between the N drive components (D1, . . . , DN) and the three input components (R, G, B), at least one linear equation defining a value for a combination of a first subset of the N drive components (D1, . . . , DN) and a second subset of the N-drive components (D1, . . . , DN) to obtain an extended set of equations. The first subset comprises a first linear combination (LC1) of 1≦M1<N of the N drive components (D1, . . . , DN), and the second subset comprises a second linear combination (LC2) of 1≦M2<N of the N drive components (D1, . . . , DN). The first and the second linear combination are different. The method further comprises determining (10) a solution for the N drive components (D1, . . . , DN) from the extended set of equations.
