Unique method for performing zoom-in and zoom-out operations with horizontal and vertical video decimation within a wireless device having a video display

A wireless terminal that comprises:

• a Radio Frequency (RF) front end;
• a baseband processor communicatively coupled to the RF front end;
• a camera operable to capture graphical images;
• a display screen operable to display graphical images;
• a user interface operable to allow a user to select a portion of the captured graphical images to be displayed;
• a camera interface that receives captured graphical images and processes the captured graphical images for display within the display screen, and wherein the camera interface is operable to:
• determine a source resolution of the portion of the graphical image to be displayed;
• determine a native pixel resolution associated with the display screen;
• determine a complex decimation pattern, wherein the complex decimation pattern allows the graphical image to be resized from the source resolution of the portion of the graphical image to be displayed to a decimated resolution operable to be displayed within the native resolution of the display screen;
• decimate the graphical image according to the complex decimation pattern;
• and
• a video processor operably coupled to the camera interface, wherein the video processor is operable to process video information within the wireless terminal according to a video standard.

A video processing module within a wireless terminal operable to perform complex decimation on graphical images to be display on a display screen within the wireless terminal comprising:

• a graphics interface operable to receive an original graphical image to be presented on the display screen, wherein a source resolution is associated with the original graphical image;
• a display screen having a native pixel resolution, wherein the display screen is operably coupled to the graphics interface, and wherein the graphics interface is operable to:
• select a portion of the original graphical image to be presented on the display screen;
• determine a complex decimation pattern that allows the selected portion of the original graphical image to be resized from its source resolution to a decimated resolution operable to be displayed within the native resolution of the display screen;
• decimate the selected portion of the original graphical image according to the complex decimation pattern;
• and
• provide the decimated graphical image to the display screen;
• and
• a video processor to process the original graphical image.
