Patent ID: 7688335

Claim:
A method of rendering a source image defined by source pixel data onto a display having tiled there across substantially identical display pixel units, where each of the substantially identical display pixel units includes independently-driveable display sub-pixel units, where the source pixel data defines said source image as sampled image points corresponding to a first set of sub-pixel color samplers that are spatially organized according to a prespecified first sub-pixel format, where said independently-driveable display sub-pixel units correspond to a second set of sub-pixel color samplers that are spatially organized according to a prespecified second sub-pixel format different from the first sub-pixel format, where the color samplers of each of said first and second sub-pixel formats include samplers for first, second and third colors, the first, second and third colors being different from one another, the method comprising: for each given one of the first, second and third colors, respectively determining locations of geometric centers of implied color sourcings represented respectively by the sub-pixel color samplers associated with said first format and the given one color, each of the determined geometric centers defining an implied source sampling point for the respective given one color; and for each given one of the first, second and third colors, respectively defining implied source sample areas as bounded by generally shared hypothetical lines that are disposed substantially equidistant between said implied source sampling points of the given one color, with each of the hypothetical lines except edge of source image ones being shared by at least two of the implied source sample areas; attributing color luminance values to each of the implied source sample areas in accordance with respective luminance values attributed to the first set of sub-pixel color samplers and the source image; and generating signals for driving said independently-driveable display sub-pixel units of the display to render the source image, the driving being done as a function of overlap-area proportional color luminance contributions associated with respective same colored ones of said implied source sample areas that become disposed contributingly adjacent to corresponding ones of the display sub-pixel units when the implied source sample areas are hypothetically overlaid across the display.
