Abstract
A method of presenting a selected portion of 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 selected portion of the image allows the selected portion of the original graphical image to be resized from the source resolution 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.
