  • Patent number: 8184904
    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.

  • Patent number: 7949907
    Abstract: A programmable logic device is presented. The device comprises a plurality of logic elements and a plurality of I/O pins; a multiplexer and/or a de-multiplexer unit. The multiplexer and/or multiplexer unit is coupled between said logic elements and I/O pins. The device further comprises a control unit for generating control signal/s for selecting one of the inputs of the multiplexer and/or one of the outputs of the de-multiplexer. The control unit includes inputs for receiving a first clock signal, a second clock signal and indicators, said indicators being indicative of a phase skew relation amongst the clock signals. The control unit being configured for generating adaptively adjusted control signal/s according to the clock signals and indicators, said control signal/s are adaptively adjusted for eliminating impact of the phase skew amongst the clock signals.

  • Patent number: 7916219
    Abstract: A technique for improving image quality using dynamic gray scale correction, in one example embodiment, includes dynamically computing non-linear gamma curves using histogram data extracted from a current video frame. A gray scale correction is then dynamically applied to each pixel in the current or next video frame as a function of the computed non-linear gamma curves.
