Embodiment Construction

[0024] An improved image processing system is described herein that can be used to process images to reduce the perception of ghosting, and / or as part of a display system that processes images and displays them.

[0025] Since two-view stereo is only an approximation of natural depth perception, and since images are always displayed in the same plane in the depth direction, i.e., the screen, stereoscopic 3D display requires a separation between focal length and vergence, viewing stereoscopic 3D images already requires An increased perceptual burden on the Human Visual System (HVS), so ghosting should not make the situation worse. Ghosting introduces conflicting perceptual depth cues, also known as retinal competition, in which the stereoscopic process of the human visual system selectively attempts to merge intended and unintended edges for depth perception. This leads to a further increase in cognitive load. By performing perceptual deghosting, the synthesized stereoscopic 3...

Abstract

Where images are displayed such that unintended light is also included and that light cannot be fully subtracted from the displayed image, an image processor compensates by compensating for the remaining light using perceptual models. In some cases, the perceptual model includes a plurality of user sensitivities and computation is performed, at least in part, based on expected user sensitivity to light pollution in portions of the images. The perceptual model might include a contrast sensitivity function, threshold-vs-intensity, saliency prediction and visual masking. The model might include artist indications of view attention. A light pollution likelihood map might be used to reduce the amount of computation needed, using a likelihood measure to determine an amount of computation to perform.

Description

[0001] Citing related applications [0002] This application claims priority to U.S. Provisional Application No. 61 / 296,465, entitled "Perception-Based Compensation of Unintended Light Pollution of Images for Projection Display Systems," filed January 19, 2010, which is adopted in its entirety for all purposes It is incorporated by reference and constitutes a part of this application. technical field [0003] The present invention relates generally to optical systems, and more particularly to image compensation to account for light pollution as part of a display. Background technique [0004] Where a certain image is to be viewed by an audience, ideally, each area of ​​the screen (or the receiving surface where it is projected) should reflect the desired color and intensity to the audience at the desired time. However, there are physical constraints that cause light pollution that includes reflections or re-reflections of light from one or more screen areas, including unin...
