Abstract:
1. In a processing device coupled to a display device, a method of improving image clarity at the display device by determining a desired position for the image to be displayed, the method comprising acts of: generating a representation of an image to be displayed on a display device, the representation configured to be moved by sub-pixel positioning in a grid space; calculating a first pixel homogeneity score for the representation based on a rendering of the representation at a first position within the grid space; calculating a second pixel homogeneity score for the representation based on a rendering of the representation at a second position within the grid space, the first and second pixel homogeneity scores indicating the uniformity of state for sub-pixels within one or more individual pixels in the grid space; comparing the first pixel homogeneity score to the second pixel homogeneity score; and based on the comparison, determining which position the image should be displayed on the display device in order to sharpen rendering of the image.
