ABSTRACT:
A method of displaying a high resolution multicolor image on a lower resolution display. The image comprises a plurality of image pixels containing at least first and second image subpixels having first and second colors. The image is displayed on a display having display pixels comprising at least first and second spatially offset display subpixels capable of displaying the first and second colors, respectively. In the method, the first display subpixel is displayed with an intensity which is a function of the intensities of at least two first image subpixels having positions extending over a first region having an area greater than the area of the first display subpixel. The first region is approximately centered on the position of the first display subpixel. A second display subpixel is displayed with an intensity which is a function of the intensities of at least two second image subpixels having positions extending over a second region having an area greater than the area of the second display subpixel. The second region is approximately centered on the position of the second display subpixel. By using a different centered region for each separate subpixel of a composite RGB display picture element in transforming a high resolution multicolor image to a lower resolution display, higher quality images are produced as compared to using a single region for each composite RGB display picture element.
