Abstract: A method, system and computer-readable medium process data for a display that includes color sub-pixels. Pixel data in a first subpixel format is received and converted to sub-pixel rendered data, generating sub-pixel rendered data in a second subpixel format, different from the first subpixel format. Converting the pixel data to the sub-pixel rendered data includes applying a first color balancing filter when at least one of a black horizontal line, a black vertical line, a white horizontal line, a white vertical line, a black edge, and a white edge is not detected in the pixel data. A second color balancing filter is applied if intensities of first and second color sub-pixels of the pixel data being converted are not equal. The sub-pixel rendered data is outputted for rendering on a display substantially comprising the second subpixel format.

Abstract: Systems and methods are disclosed to effect a gamut conversion of source image data to a target image data set for rendering on a device with possibly a different gamut. One gamut conversion system comprises an input channel means, a gamma unit, a chorma/luma unit, a hue angle calculator, and a gamut conversion unit. The input channel means receives source image data. The gamma unit converts the source image data into perceptually uniform space data. The chroma/luma unit converts the preceptiually uniform space data into a format comprising chroma and luma components. The hue angle calculator receives at least the chroma components from the chroma/luma unit and calculates hue angles for the source image data based on received components. The gamut conversion unit derives gamut conversion values to apply to the components of the source image data using a gamut conversion table.

Abstract: The systems detect movement of text or areas of high spatial frequency in one frame to another frame. If such movement is detected and meets a certain level or threshold, the subpixel rendering processing of such text or areas of high spatial frequency can be changed.

Abstract: A display system includes a subpixelated display panel having subpixels in two saturated primary colors. In one embodiment, the primary colors are selected so as to be a substantially metameric pair for an achromatic color such as white. Information display efficiencies arise from utilizing a checkerboard arrangement for the two primary colored subpixels and from using subpixel rendering algorithms to render an image on the display. The bichromatic display may display a black and white image combined with a monochromatic image, or may provide the capability to overlay a first image from a first image source carried on a chromatic channel onto a second image from a second image source carried on a luminance channel, where the first image source detects light wavelengths that the Human Vision System is not sensitive to, such as infrared light. This latter embodiment of the bichromatic display system is suitable for night vision devices.

Other embodiments provide methods for modifying the output color produced by the gamut mapping operation for input colors that are on the darker or brighter surfaces of the input color gamut, or for certain out-of-gamut colors such as yellow colors.
