    摘要: Active diffuser frame system (A) for a video display (D) provides ambient lighting in viewer object mode and relies on real-time video input only, with no separate lighting script required. The system uses a controllable light source, and multiple inputs to improve realism and fidelity. Video inputs include actual display light; sensing of display light; and the video display signal. The frame can include a light modulator, or a goniophotometric or goniochromatic element to change character (intensity, color) of ambient light as a function of viewing angles, or a photoluminescent emitter for new chromaticities outside the display color gamut. The frame can split light between the viewer and the frame input, and can derive an added video signal to drive selected display pixels to boost output of display light into the frame.

    摘要: Extracting and processing video content encoded in a rendered color space to be emulated by an ambient light source, comprising extracting dominant color information from a video signal and transforming the color information through unrendered color space using tristimulus primary matrices to form a second rendered color space for ambient distribution. Steps include quantizing the rendered color space to form an assigned color distribution, such as by reducing possible color states, or binning to form superpixels; and selecting a dominant color using a mode, mean, median, or weighted average of pixel chromaticities. A color of interest can be further analyzed to produce a true dominant color, and past video frames can guide selection of dominant colors in future frames.

    摘要: Extracting and processing video content encoded in a rendered color space to be emulated by an ambient light source, using perceptual rules for intelligent dominant color selection. Steps include quantizing the video color space; performing dominant color extraction by using a mode, median, mean, or weighted average of pixel chromaticities; applying perceptual rules to further derive dominant chromaticities via [1] chromaticity transforms; [2] a weighted average using a pixel weighting function influenced by scene content; and [3] extended dominant color extraction where pixel weighting is reduced for majority pixels; and [4] transforming the dominant color chosen to the ambient light color space using tristimulus matrices. A color of interest can be further analyzed to produce a true dominant color, and past video frames can guide selection of dominant colors in future frames.
