FLICKER-FREE ADAPTIVE THRESHOLDING FOR AMBIENT LIGHT DERIVED FROM VIDEO CONTENT MAPPED THROUGH UNRENDERED COLOR SPACE |
摘要 |
Flicker free operation of ambient light sources that emulate video content during low luminance conditions, where the ambient light source is output thresholded so that an on/off change of state of the ambient light source can be initiated after an intensity variable passes one or two thresholds. Output thresholding is used when extracting and processing video content encoded in a rendered color space, which can be decoded into frames tapped by an interframe interpolation process using only color information from selected frames, such as extracting average or other color information from an selected screen regions. Negative gamma correction helps prevent garish or inappropriate chromaticities and lumina.
