    摘要: Sub-pixel rendering with gamma adjustment allows the luminance of the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel. For each of a subset of input sampled data indicating a region of an input image, a gamma-adjusted data value is generated for each input image data value in the subset using a local average of at least two input image data values. A sub-pixel rendering operation uses the subset of gamma-adjusted data values and the subset of input image data values to produce an output data value for each sub-pixel element on the display panel. A plurality of output data values collectively indicates an output image. The gamma adjustment 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 improve image contrast in high spatial frequency portions of an image.

    摘要: A display system (110) has a subpixel array (120) and a light source (140). In normal mode, image data (164) are processed by the display system to generate subpixel values (174) for the subpixels (130) and to generate a light source control value (BL) for the light source (140). In bypass mode suitable for testing new types of image-data processing, the subpixel values and the light source control value are generated by an external system (210) and are provided to the display system which is operated in bypass mode. The light source control value is not provided separately from the subpixel values but is encoded into some bits of the subpixel values for compatibility with older interfaces. The light source control value is encoded into the subpixel values' MSBs in case the subpixel values could be truncated. Other features are also provided.
