Unique method for performing horizontal and vertical video decimation within a wireless device
First Claim
1. A method to present a graphical image within a wireless terminal, which comprises:
- receiving an original graphical image to be presented on a display screen;
determining a source resolution of the original graphical image;
determining a native pixel resolution associated with the display screen;
determining a complex decimation pattern, wherein the complex decimation pattern allows the original graphical image to be resized from the source resolution of the original graphical image to a decimated resolution operable to be displayed within the native resolution of the display screen;
decimating the original graphical image according to the complex decimation pattern; and
presenting the decimated graphical image on the display screen.

Abstract
A method of presenting graphical images within a wireless terminal that includes receiving an original graphical image, having a source resolution, to be presented on a display screen. The native pixel resolution of the display screen may differ from that of the original graphical image. A complex decimation pattern when applied to the image allows the original graphical image to be resized from the source resolution of the original graphical image to a decimated resolution operable to be displayed within the native resolution of the display screen. Decimated pixels need not be further processed to reduce the processing requirements imposed on the system processor. Operations normally associated with the decimated portions of the image may be offloaded from the processing module to improve system efficiency.
