摘要： A level compression and/or gradation conversion of a color video signal are performed without causing any change in the hue of a picture-represented by the color video signal. The knee compression and/or gradation conversion are carried out by multiplying' red, green and blue primary color signals by a luminance gain, while the hue and saturation remain unaffected. If the level of any of the primary color signals still exceeds a predetermined threshold level, the saturation conversion is executed by using the saturation gain and the lumizlanc.e signal supplied from a controller. In the saturation conversion operation, the maximum level of at least one of the red, green and blue primary color signals is made coincident with the predetermined threshold level while the hue and luminance of the picture represented by the color video signal are maintained unchanged.

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.

Red, green and blue signals are input to a chroma composition ratio determination circuit (550) that generates and outputs the RGB color composition ratio (α : β : γ) . A chroma suppression luminance signal generating circuit (560) then generates a chroma suppression luminance signal Ya based on the RGB signals and the color composition ratio. A chroma suppression gain determination circuit (570) outputs the gain for the chroma suppression luminance signal based on a table in which output gain setting values corresponding to the chroma suppression luminance signals are recorded. Multipliers (581, 582) then multiply input color-difference signals Cr, Cb by the gain and output a suppressed color-difference signals (Cr x G, Cb x G) according to the color composition ratio (α:β:γ)
