摘要： A method of facilitating the display of an image. The method includes, in a display system comprising a display panel having pixels and a backlight having individually addressable colored light emitters configured to provide light to the pixels of the display panel, receiving image data corresponding to an image for display upon the display panel, the pixels each having a color to be displayed, so as to collectively display the image. The method also includes, for each pixel, evaluating whether the corresponding color to be displayed is out-of-gamut to the each pixel, so as to form a set of out-of-gamut pixels. A set of virtual primaries is determined so as to define intensities of light emitted by the colored light emitters of the backlight during display of the image, the virtual primaries determined according to the colors of the set of out-of-gamut pixels.

摘要： Nonlinear compression of high precision image data (e.g., 12-bits per subpixel) conventionally calls for a large sized lookup table (LUT). A smaller sized and tunable circuit that performs compression with piecewise linear compressing segments is disclosed. The piecewise linear data compressing process is organized so that lumping together of plural ‘used’ high precision value points into one corresponding low precision data value point is avoided or at least minimized. In one embodiment, the compressed data is image defining data being processed for display on a nonconventional display screen where the piecewise linearly compressed data can be stored adjacent to other image data in a frame buffer where a composite image is assembled.

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： A method of blending image data that includes displaying a first portion of an image from a first set of pixels according to a first mode in which color values of sub-pixels of the first set of the pixels are determined according to time-averaged colors of the corresponding backlight emitters. The method also includes displaying a second portion of the image from a second set of the pixels according to a second mode in which color values of sub-pixels of a second set of the pixels are determined independently for each of the colors of the corresponding backlight emitters. At an interface between the first portion and the second portion, the first portion and the second portion are generally linearly blended so as to form a blended portion of the image, and the blended portion is displayed.

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.

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： Sub-pixel rendering with gamma adjustment allows the luminance for the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel, while the chrominance can match the linear response of the human eye's chrominance channels. The gamma correction allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may be optimized for the gamma transfer curve of a display device in order to improve response time, dot inversion balance, and contrast.
