CONVERSION OF A SUB-PIXEL FORMAT DATA TO ANOTHER SUB-PIXEL DATA FORMAT
First Claim
1. 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, for use in sub-pixel rendering an image on a display specified in a second sub-pixel format, each of said first and second sub-pixel formats comprising a plurality of colored sub-pixels, the method comprising:
- determining a geometric center of each colored sub-pixel of said first format to define a sampling point; and
defining each said implied sample area by forming lines that are substantially equidistant between said sampling point of one said colored sub-pixel and said sampling point of another neighboring same color colored sub-pixel.

Abstract
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.
