Patent ID: 8447106

Claim:
A method of dynamically and adaptively enhancing user chosen colors on a frame-by-frame basis of an incoming digital video signal, comprising: forming a value-saturation 2D-histogram for each of the user chosen colors using a substantially current video frame, wherein the substantially current video frame includes a plurality of pixels; dynamically computing a saturation dependent value bright-gain, adaptive to slow or fast moving image sequences, for each of the user chosen colors using the corresponding value-saturation 2D-histogram of the substantially current video frame and corresponding value-saturation 2D-histogram information and a saturation dependent value bright-gain of a substantially previous video frame; determining which one of the dynamically computed saturation dependent value bright-gains associated with the user chosen colors to be applied on a per-pixel basis by comparing Hue, saturation and value (HSV) components of each pixel with predefined HSV ranges of various user chosen colors, respectively; and applying the determined saturation dependent value bright-gain to value component on the per-pixel basis in the substantially current or next video frame.
