ABSTRACT:
A method interpolating pixel values includes 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. Another difference value is calculated 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. A determination is made as to 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, interpolation is performed 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.
