Abstract: System and method for dynamically and adaptively enhancing user chosen colors on a frame-by-frame basis of an incoming digital video signal using a saturation gain is disclosed. In one embodiment, a saturation 1D-histogram for each of the user chosen colors is formed using a substantially current video frame. Further, a saturation gain, adaptive to slow or fast moving image sequences, is dynamically computed for each of the user chosen colors of the substantially current video frame using the corresponding saturation 1D-histogram of the substantially current video frame and corresponding saturation 1D-histogram information and a saturation gain of a substantially previous video frame. Furthermore, which one of the dynamically computed saturation gains associated with the user chosen colors to be applied on a per-pixel basis is determined. The determined saturation gain is applied to saturation component on the per-pixel basis in the substantially current or next video frame.

Abstract: A method and apparatus for dynamically, adaptively and/or concurrently enhancing and diminishing of colors in digital video images is disclosed. In one embodiment, a method includes dynamically computing a saturation gain, adaptive to slow or fast moving image sequences, for each user chosen color of a substantially current video frame, dynamically computing a saturation dependent value gains, adaptive to slow or fast moving image sequences, for each user chosen color of the substantially current video frame, determining which of the dynamically computed saturation gain and a saturation dependent value gains associated with each user chosen color or no gain is 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 and/or saturation dependent value gain on the per-pixel basis, in the substantially current or next video frame.
