Abstract

A method of and device for providing image frames is provided. The method includes outputting portions of a first frame that have changed relative to the one or more other frames without outputting portions of the first frame that have not changed relative to the one or more other frames. Each of the portions are determined to be changed if a rendering engine has written to a frame buffer for a location within boundaries of the portion. This outputting is done in response to one or more portions of a first frame having changed relative to one or more other frames.
