Abstract

A method that incorporates teachings of the subject disclosure may include, for example, mapping image pixels of media content to a first portion of display pixels of a display to create mapped pairs having a mapped image pixel and a mapped display pixel, where the display has at least one of a greater number of horizontal or vertical pixels than the media content and for each mapped pair, one or more values associated with the mapped image pixel are assigned to the mapped display pixel, assigning blended mapped values to unmapped display pixels in a second portion of the display pixels, where, for each unmapped display pixel, the blended mapped value is a statistical compilation of one or more values assigned to the mapped display pixels that are adjacent to the unmapped display pixels, and presenting the mapped and unmapped display pixels at the display. The method includes other embodiments.
