Abstract:
1. A method of converting source pixel data signals corresponding to a first spatial distribution format of differently colored source subpixels of a respective, potentially renderable source image to output pixel data signals corresponding to a different second spatial distribution format of differently colored output subpixels of a respective renderable output image, wherein the source pixel data signals and the output pixel data signals are physical real signals, the method being implemented by an automated machine and comprising: implicitly assigning implied source sample areas to the source subpixels of the first format and implicitly assigning to each implied source sample area a data value corresponding to an implied luminance output from the corresponding subpixel of said first format in accordance with said source pixel data, the implied luminance output being that of the potentially renderable source image if the source image is actually rendered; implicitly assigning implied resample areas to the output subpixels of the second format in accordance with the spatial distribution of the output subpixels as defined by the second format; for each color plane, implicitly overlaying a scaled or not scaled version, as indicated by a supplied overlay scaling ratio, of the implied source sample areas of the corresponding color over the implied resample areas of the same corresponding color; in accordance with said implicit overlaying of the source sample areas over the output resample areas per the supplied overlay scaling ratio, automatically selecting in said automated machine, respective contribution weighting parameters to be applied to the assigned data values of the source sample areas of each color plane for purpose of generating area overlap related drive signals for each color plane; for each output resample area of a given color plane, multiplying in said automated machine, the data values of implicitly overlying and contributing source sample areas by their respectively selected contribution weighting parameter and adding to one another the weighted data values to thereby define and generate in said automated machine, a respective output pixel data signal for each said resample area, the generated output pixel data signal being a physical real signal.
