    摘要: A method of determining implied sample areas for each data point of each color in a source pixel data specified in a first sub-pixel format is used for sub-pixel rendering an image on a display specified in a second sub-pixel format. Each of the first and second sub-pixel formats comprises a plurality of colored sub-pixels. The method comprises determining a geometric center of each colored sub-pixel of the first format to define a sampling point; and defining each implied sample area by forming lines that are substantially equidistant between the sampling point of one colored sub-pixel and the sampling point of another neighboring same color colored sub-pixel. A similar technique may be used for determining resample areas for computing color values for rendering an image specified in a first sub-pixel format on a display substantially comprising a plurality of colored sub-pixels arranged in a second sub-pixel format.

    摘要: A method of producing a plurality of filter kernels comprised of filter coefficients for use in a sub-pixel rendering operation comprises calculating a plurality of filter coefficients for each filter kernel by dividing a spatial area of an input image that is overlapped by a portion of a spatial rendering area by a total area of the spatial rendering area using floating point arithmetic. The method further comprises multiplying each filter coefficient by a divisor to produce a filter product such that a sum of all filter products produces a filter sum that equals the divisor. Then a binary search operation is performed to find a round off point for the filter sum such that when each filter coefficient is converted to an integer, a sum of the filter coefficients equals the divisor. The filter coefficients are then converted to integers using the round off point.

    摘要: Input image data indicating an image is rendered to a display panel in a display device or system that is substantially configured with a three primary color or multi-primary color subpixel repeating group using a subpixel rendering operation based on area resampling techniques. Examples of expanded area resample functions have properties that maintain color balance in the output image and, in some embodiments, are evaluated using an increased number of input image sample points farther away in distance from the subpixel being reconstructed than in prior disclosed techniques. One embodiment of an expanded area resample function is a cosine function for which is provided an example of an approximate numerical evaluation method. The functions and their evaluation techniques may also be utilized in constructing novel sharpening filters, including a Difference-of-Cosine filter.

    摘要: In a first embodiment, a display system comprises a display panel with 4 or more colored subpixels. The display system receives input image data specified in a first color space and outputs image data specified in a second color space. The display system further comprises a gamut mapping module for mapping the input image data specified in the first color space to image data specified in the second color space. The gamut mapping module clamps out-of-gamut colors using at least a first clamping system and a second clamping system. The first and second clamping systems yield first and second clamped values. A weighting module produces a resulting clamped value from the first and second clamped values. A final output image value is derived from the resulting clamped value. Other embodiments of the display system include pre-reduction modules and adjustable GMA modules.
