Abstract
A method and apparatus for dynamically blending a plurality of image input layers include processing that begins by determining color base (e.g., color space, colorimetries and/or any defining characteristics relating to the display of a video signal and/or graphics data) of each of a plurality of image input layers. An image input layer corresponds to a window, display area and/or background of a display capable of presenting separate images at one time, wherein the separate images originate from separate video and/or graphics sources. The processing continues by determining an output color base of an output, where the output color base corresponds to the color base capabilities of the video equipment (e.g., RGB output). The processing then continues by converting, for each of the plurality of image input layers that has a different color base than the output color base, the color base to match the output color base thereby producing converting image layers. The processing continues by blending each of the converted image layers with each of the plurality of image input layers that has a color base that matches the output color base to produce an output image.
