Abstract
A method and apparatus for blending a plurality of image input layers include processing that begins by converting each of a plurality of image input layers that have a color base that differs from a color base of a display into a image layer having the color base of the display, thereby producing converting image layers. The color base of the image input layers and of the output include the colorimetries of various standardized video signals, color space, and/or any other defining display characteristics of video signals that is currently standardized or maybe standardized. Further note that an image input layer corresponds to a window, a background and/or a display area of a display, where the display is capable of presenting more than one image, where the images originate from different video and/or graphics data sources (e.g., a television signal, and a computer application display). The processing continues by blending each of the converted image layers with each of the plurality of image input layers that have the color base of the display to produce a blended output having the color base of the display.
