Abstract:
1. A method of interpolating pixel values comprising: calculating a difference value between pixel values corresponding to a first display pixel on a first display line and a second display pixel on a second display line, the first and second display pixels defining a possible edge angle of an object on a display; calculating another difference value between pixel values corresponding to a third display pixel of the first display line and a fourth display pixel of the second display line, the third and fourth display pixels defining a second angle on the display; determining whether the difference value is less than or equal to the another difference value; and when the difference value is less than the another difference value, interpolating between a pixel value corresponding to a selected display pixel on the first display line and another pixel value corresponding to a selected display pixel on the second display line to generate a pixel value corresponding to a display pixel on a third display line.
