A computer-implemented method of modifying image data is presented. The method entails detecting a triggering pattern based on colors and saturation values of a group of pixels, wherein at least one of the pixels includes a plurality of subpixels, and wherein the triggering pattern includes at least a portion of one of a diagonal line and a vertical line. The method changes the image data for a specific subpixel in the group of pixels, wherein the specific subpixel is located in or adjacent to the diagonal line or the vertical line. Alternatively, the method entails detecting a border between saturated-color subpixels and non-saturated-color subpixels, and adding luminance to white subpixels at the border. A display system configured to execute the above methods and a computer-readable medium storing instructions for executing the above methods are also presented.

An apparatus and method for providing low power subpixel rendering are provided. The method includes receiving image data for a first pixel of a captured image, receiving image data for a second pixel of the capture image, determining a first saturation value of the first pixel and a second saturation value of the second pixel, determining a maximum saturation value based on the first saturation value and the second saturation value, and rendering a subpixel value using a one dimensional filter or a unity filter based on the determined maximum saturation value.

Low power subpixel rendering on RGBW display

Facilitating the display of an image in a display system comprising a display panel having sub-pixels, and a backlight having individually addressable colored light emitters configured to provide light to the sub-pixels. From received image data, sub-pixel color values corresponding to color values transmitted by respective ones of the sub-pixels for display of the image are determined. From the image data, backlight values corresponding to brightnesses of ones of the colored light emitters for display of the image are determined, as are a portion of the sub-pixel color values and a portion of the backlight values that collectively correspond to a saturated or near-saturated yellow color in the displayed image. The backlight values are adjusted by increasing an amount of yellow light to be emitted by emitters of the backlight, and the color values are adjusted by decreasing an amount of yellow light to be transmitted by the sub-pixels.

Method for reducing simultaneous contrast error

A side-channel encoding method for an electronic device is provided. The side-channel encoding method includes converting an original image into a down image by downscaling the original image, converting the down image into an up image by upscaling the down image, calculating a pixel-specific luminance variation between the original image and the up image by using a local average luminance for each pixel included in the original image, converting the pixel-specific luminance variation into a first variation binary signal by binarizing the luminance variation, converting the first variation binary signal into a second variation binary signal by simplifying the first variation binary signal, and outputting the second variation binary signal by including the second variation binary signal in the down image.

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.
