    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: Display systems and image processing methods process pre-subpixel rendered images embedded in input color image data. The display systems include a pre-subpixel rendered (P-SPR) image detector that detects locations of a marking code that marks the portion of the input data that has been pre-subpixel rendered and which is ready for direct display. Several display system embodiments comprise first and second image data paths; the input data that requires subpixel rendering proceeds along the first path while the P-SPR image data proceeds along the second path. Another display system embodiment processes the combined input and P-SPR data along a single data path. Techniques for marking and detecting P-SPR image data using two distinct marking codes are presented in the context of the subpixel layout of the display. Techniques for using P-SPR data to display high-quality graphical symbols (e.g., font glyphs) are suitable for small, low-cost display devices.

    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: Local contrasts within segments of an image are maintained even as the image is gamut mapped to a new gamut space where the remapping, if done straight forward, may result in loss of local contrasts. Display systems described herein use a selective compression unit that first surveys segments of the image to determine which might lose local contrast due to gamut mapping and gamut clamping. Selective compression amounts are determined for respective segments so as to substantially maintain local contrast of the image data within the respective segments.
