1. A system for generating an image for display comprising:
- a computer processor with associated digital memory and output element, said processor being operative to employ an optimization-based binocular tone mapping framework;
said computer processor and associated memory being configured to;
receive in digital representation as a source a high-dynamic range image of a source high dynamic range image;
produce a first low-dynamic range image directly from said high-dynamic range image;
synthesize a corresponding second low-dynamic range image from said high-dynamic range image, wherein extra image space is used to enhance image content while preserving visual information, andpresent said two low-dynamic range images separately to eyes of a viewer to be processed in the brain of the viewer via human visual perception phenomenon of binocular single vision,said tone mapping framework being guided by a metric of a binocular viewing comfort predictor (BVCP) based upon brightness, contrast and contour differences between two views in order to assure stable formation of binocular single vision for the viewer and avoid viewing discomfort.

Abstract
In a computer-based graphics imaging system, binocular tone mapping is employed with an optimization-based framework to generate a binocular single vision image with more visual richness than a single tone-mapped image, the binocular tone mapping being guided by a binocular viewing comfort predictor (BVCP) metric in order to assure stable formation of binocularly tone-mapped image pairs, so that visual information content of the image pair can be maximized without triggering visual discomfort.

11. A method for generating an image for display comprising:
-
receiving, in a digital memory under control of a computer processor in digital representation as a source, a high-dynamic range image of a source high dynamic range image; producing via said computer processor a first low-dynamic range image directly from said high-dynmaic range image; synthesizing via said computer processor a corresponding second low-dynamic range image from said high-dynamic range image, wherein extra image space is used to enhance image content while preserving visual information; and presenting, via a binocular display device said two low dynamic range imaged separately to eyes of a viewer to be processed in the brain of the viewer via human visual perception phenomenon of binocular single vision; wherein a tone mapping operation is guided by a metric of a binocular viewing comfort predictor (BVCP) based upon brightness, contrast and contour differences between two views in order to assure stable formation of binocular single vision for the viewer and avoid viewing discomfort. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
