A method of determining implied sample areas for each data point of each color in a source pixel data specified in a first sub-pixel format is used for sub-pixel rendering an image on a display specified in a second sub-pixel format. Each of the first and second sub-pixel formats comprises a plurality of colored sub-pixels. The method comprises determining a geometric center of each colored sub-pixel of the first format to define a sampling point; and defining each implied sample area by forming lines that are substantially equidistant between the sampling point of one colored sub-pixel and the sampling point of another neighboring same color colored sub-pixel. A similar technique may be used for determining resample areas for computing color values for rendering an image specified in a first sub-pixel format on a display substantially comprising a plurality of colored sub-pixels arranged in a second sub-pixel format.

What is claimed is: 1. A method of rendering a source image corresponding to source pixel data on a display having a plurality of pixel units,where each of the pixel units includes independently-drivable sub-pixel units,where the source pixel data is related to a plurality of hypothetical pixel units corresponding to a first set of sub-pixel color samplers that are spatially organized according to a prespecified first sub-pixel format,where the 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 the first and second sub-pixel formats include samplers for at least three colors being different from one another,the method comprising:for each given one of at least three colors, respectively determining locations of geometric centers of the hypothetical pixel units related to the first sub-pixel color samplers associated with the 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; andfor each given one of the at least three colors, respectively defining implied source sample areas as bounded by shared hypothetical lines that are disposed equidistant between the implied source sampling points of the given one color, with at least one hypothetical line 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 hypothetical pixel units and the source image; andgenerating signals for driving the 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 the implied source sample areas that become disposed on corresponding ones of the display sub-pixel units when the implied source sample areas are hypothetically overlaid across the display.
