Claim One:
1. A method for dominant color extraction from video content encoded in a rendered color space (RGB) to produce a dominant color (DC) for emulation by an ambient light source ( 88 ), comprising: [1] Quantizing at least some pixel chromaticities (Cp) from said video content in said rendered color space to form a distribution of assigned colors (AC); [2] Performing dominant color extraction from said distribution of assigned colors to produce a dominant color by extracting any of: [a] a mode of said assigned colors; [b] a median of said assigned colors; [c] a weighted average by chromaticity of said assigned colors; [d] a weighted average using a weighting function (W(i,j,R)); [3] Transforming said dominant color from said rendered color space to a second rendered color space (R′G′B′) so formed as to allow driving said ambient light source.
