Abstract

Input video signals characterized by a source electro-optical transfer function (EOTF) are to be blended and displayed on a target display with a target EOTF which is different than the source EOTF. Given an input set of blending parameters, an output set of blending parameters is generated as follows. The input blending parameters are scaled by video signal metrics computed in the target EOTF to generate scaled blending parameters. The scaled blended parameters are mapped back to the source EOTF space to generate mapped blending parameters. Finally the mapped blending parameters are normalized to generate the output blending parameters. An output blended image is generating by blending the input video signals using the output blending parameters. Examples of generating the video signal metrics are also provided.
