摘要： A method is described which converts a three primary color input signal (Cx, Cy, Cz) into N drive signals (Pl, ..., PN) to drive N > 3 primary colors of a multi-primary color display (3). The method determines (1) a valid range (VS) wherein the N drive signals (Pl, ..., PN) have valid values by performing the steps of (i) defining 3 functions representing 3 of the drive signals (Pl, P2, P3) as a function of the remaining N-3 drive signal(s) (P4, ..., PN), and (ii) calculating (1) a common range in a space formed by the N-3 drive signal(s) (P4, ..., PN) wherein each one of the 3 functions has valid values. The method selects (2) a point from the common range to determine the N drive signals (Pl, ..., PN).

摘要： A method of enhancing details in an input image. The input image comprises input pixels, which have input pixel values (IPV) limited to a range (RA). The method comprises average filtering (1) the input pixel values (IPV) to obtain average brightness values (LV). A luminance mask is applied (2) to the average brightness values (LV) to obtain masked values (MV) which are different for average brightness values (LV) in a sub-range (SR) of the range (RA) than for pixels outside the sub-range (SR). The input pixel values (IPV) are detail filtered (3) to obtain detail values (HV) indicative for an amount of detail. A non-linear function (NLF) is applied (5) on the input pixel values (IPV) to obtain for each input pixel value (IPV) a corresponding output pixel value (OPV). A gain of the non- linear function (NLF) is dependent on both the masked value (MV) and detail value (HV) which both are determined for the particular input pixel. The gain is higher for input pixels with input pixel values (IPV) outside the sub-range (SR) than for input pixels with input pixel values (IPV) inside the sub-range (SR). And the gain is higher for input pixels for which the detail value (HV) indicates more high frequency content in the image portion around the particular input pixel than for input pixels for which the detail value (HV) indicates less high frequency content.

摘要： A color display device, a drive circuit for a color display device, a method, a signal and a computer-readable medium for reducing electro-optical cross talk that occurs in a display that is operated in Spectrum Sequential mode is disclosed. The invention eliminates annoying visible artefacts, such as contouring, noise, or color deviation, which normally are introduced by this cross talk by compensating for the cross talk. According to embodiments of the invention, a drive signal (R',G',B') to drive picture elements of the display is altered in video processing circuitry (MPC, XTC, SC) and/or software, in dependence on one or more properties of different spectra from a light source (23, 24) in the display. The invention is implemented with little extra effort and cost in known LCD displays.
