    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： Displays systems and methods for producing a single scaling factor to image data values are disclosed. In one embodiment of a display system uses a post-scaling module. A post-scaling unit for scaling image data values is constructed as a function of many scaling requirements such as backlight illumination from said illumination determination unit, saturation of the image data values and out-of-gamut correction—to produce a single scaling factor. This single scaling factor may be a function of a number of scaling requirements as described herein. Some of these scaling requirements could be selected from a group scaling considerations, such as saturation based scaling, out-of-gamut scaling, and non-linear scaling. Of course, other scaling requirements may be desired and could be added as such. As further described herein, the non-linear scale module could be used to enhance dark color values and may depend on the luminance value of image data values. Once these scaling requirements are determined, there are a multitude of ways of combining them to create such a single scaling factor—including multiplying them or taking the minimum of them or a combination thereof.

    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.
