Multi-primary conversion
Abstract:
A method converts an input pixel (IPi) defined by three values (ri, gi, bi) of input primaries (RI, GI, BI) into N drive values (DSi) for driving N sub-pixels (SPi) of a pixel (PIi) of a display device (DD). The N drive values (DSi) have a valid range (VR) wherein their values occur. The N sub-pixels (SPi) emit light defined by N display primaries (DPi) of which at least four are independent. M resulting display primaries (RDi) are used (10) wherein a group of ones of the N display primaries (DPi) which are combined into a combined display primary (CDi) are replaced by the combined display primary (CDi). A first multi-primary conversion (MPC1) is performed (11) on the input pixel (IPi) to obtain resulting drive values (DRi) for the M resulting display primaries (RDi). It is checked (12) whether the M resulting drive values (DRi) have values in the valid range (VR). If the resulting drive value (DRi) of at least one of the M resulting display primaries (RDi) has a value outside the valid range (VR) the method allocates (12) a fixed value (FVi) to the resulting drive value (DRi) outside the valid range (VR), and selects (13) K out of the N display primaries (DPi). The selection includes the ones of the N display primaries (DPi) which were combined into a combined display primary (CDi) but not the display primaries (DPi) associated with the resulting drive value (DRi) outside the valid range (VR). The integer K is larger than 3. Finally the method performs (14) a second multi-primary conversion under a constraint (CO2) for the ones of the N display primaries (DPi) being combined into a combined display primary (CDi) in the first multi-primary conversion (MPC1).
Abstract(Chinese):

一种方法将由输入基色（RI，GI，BI）的三个值（ri，gi，bi）定义的输入像素（IPi）转换为用于驱动像素的N个子像素（SPi）的N个驱动值（DSi） PIi）显示设备（DD）。 N个驱动值（DSi）具有其值出现的有效范围（VR）。 N个子像素（SPi）发射由N个显示原色（DPi）定义的光，其中至少四个是独立的。 使用M个结果显示原色（RDi）（10），其中组合到组合显示器主体（CDi）中的N个显示原色（DPi）中的一组被组合的显示器主（CDi）代替。 在输入像素（IPi）上执行第一多原点转换（MPC1）（11），以获得用于M个结果的显示原色（RDi）的得到的驱动值（DRi）。 检查（12）M个导出驱动值（DRi）是否具有有效范围（VR）中的值。 如果由M个结果的显示原色（RDi）中的至少一个产生的驱动值（DRi）具有超出有效范围（VR）的值，则该方法将（12）固定值（FVi）分配给所得到的驱动值 ）在有效范围（VR）之外，并且从N个显示基色（DPi）中选择（13）K。 该选择包括被组合成组合的显示原始（CDi）的N个显示原色（DPi），而不是与有效范围（VR）之外的所得到的驱动值（DRi）相关联的显示原色（DPi）。 最后，该方法执行（14）在N个显示原色（DPi）中的N个显示原色（DPi）中的一个被组合为组合显示原色（CDi）的约束（CO 2）下的第二多原色转换 第一次多主转换（MPC1）。
