Method for scaling and cropping images for television display

摘要

A method of processing an image for display on a television screen is described. Unlike conventional method which over-expands the image, the method described herein crops the image (optionally) and scales it to fit the native resolution of the display screen without over-expanding the image. The method includes the steps of receiving a source television image having a native image resolution, scaling the source television image using a scaling ratio to produce a scaled television image having a resolution equal to or less than the native screen resolution in both a vertical and a horizontal direction, and displaying the scaled television image on the television screen. The scaling ratio may be the same or different in the vertical and horizontal directions.
