    摘要: A method of dynamic gamut control is disclosed. In accordance with a first aspect of the invention, control of the intensities of a set of color primaries illuminating associated sub-pixels of a display device is disclosed. Thus, the intensities of the light sources are controlled to control the intensities of the color primaries after the color filters. The method searches for a minimal intensity value of one color primary, which is adjusted to obtain together with the other color primaries of the set of color primaries an adjusted color gamut still containing all the colors of the set of colors.

    摘要: A method of converting a three primary color input signal comprises a first, a second, and a third input signal (C1, C2, C3) into a four primary color drive signal comprising a first, second, third, and fourth drive signal (P1, P2, P3, P4) for driving four primary colors of a multi-primary color additive display (3). Three functions (F1, F2, F3) representing the first, second, and third drive signal (P1, P2, P3) as a function of the fourth drive signal (P4) are defined. The intersection values (P4i) of the fourth drive signal (P4) are determined at a set of intersections of: the three functions (F1, F2, F3) mutually, and of the three functions (F1, F2, F3) and a line (F4) defined by the fourth drive signal (P4) being equal to itself, wherein only the intersection values (P4i) of functions having opposite signs of their first derivative are relevant. The associated first, second and third drive signals (P1, P2, P3) are calculated at (i) the intersection values (P4i) of the fourth drive signal (P4) to obtain calculated values (CV1, CV2, CV3), and (ii) at boundary values (P4min, P4max) of a valid range (VR) of the fourth drive signal (P4) wherein all drive signals (P1, P2, P3, P4) have valid values. The values of interest (CV1, CV2, CV3, P4i) comprising the intersection values (P4i) of the fourth drive signal (P4) and the associated calculated values (CV1, CV2, CV3) are determined. The maximum value (Vmax) or minimum value (Vmin) of the values of interest (CV1, CV2, CV3, P4i) at the intersection values (P4i) are calculated. And finally, the intersection value (P4i) at which the maximum value (Vmax) or minimum value (Vmin) is minimum or maximum, respectively, is selected.

    摘要: A multi-primary conversion method for converting (CON) an input vector (CIP) defining a color of an input pixel in a linear color space (X, Y, Z) into a drive vector (PD) having n components for driving n display primaries (P1, . . . , Pn) of a display color space. The drive vector (PD) comprises m sub-drive vectors (PDi) for driving m groups of the display primaries (P1, . . . , Pn). The conversion method comprises: determining (5, 6; 9, 10) in the linear color space (X, Y, Z) a position of the input vector (CIP) with respect to boundaries (CB) of at least two of three gamuts (FG, ELG, ELCG) being defined by transformed display primaries (CP1, . . . , CPn), wherein the three gamuts (FG, ELG, ELCG) indicate: a full gamut (FG) comprising all colors being reproducible with the m groups of the sub-drive vectors (PDi), an equal luminance sub-gamut (ELG) comprising all colors having equal luminance and being reproducible with each one of the m groups of the sub-drive vectors (PDi), and an equal luminance and equal chrominance sub-gamut (ELCG) comprising all colors being reproducible with each one of the m groups of sub-drive vectors (PDi) each having equal luminance and equal chrominance. Selecting (3; 12, 13) two boundary vectors (CB 1, CB2) on the boundaries (CB) of the three gamuts (FG, ELG, ELCG) to enable the input vector (CIP) to be interpolated from the two boundary vectors (CB1, CB2). Determining (3; 14) an interpolation factor (u) from the position of the input vector (CIP) with respect to the selected two boundary vectors (CB1, CB2). And, interpolating (4; 11) in the display color space the drive vector (PD) representing the color of the input vector (CIP) from the interpolation factor (u) and two boundary vectors (PB1, PB 2) in the display color space corresponding to the selected two boundary vectors (CB1, CB2) in the linear color space.
