  • Black point insertion
    Publication number: 20060181503
    Abstract: A backlight display has improved display characteristics. An image is displayed on the display which includes a liquid crystal material with a light valve. The display receives an image signal, modifies the light valve with an overdrive for a first region of the image based upon the timing of the illumination of the region, and modifies the light valve with an overdrive for a second region of the image based upon the timing of the illumination of the second region.

  • Method and apparatus for background adjustment in color reproduction devices
    Patent number: 6995866
    Abstract: A method for background adjustment. A background lightness level in an original image is estimated. Pixels are then converted to a luminance-chrominance color space. Pixels have lightness levels equal to the background lightness level are mapped to a value corresponding to white as background pixels. Chroma values for the background pixels are compared to a threshold and adjusted as needed, either by adjusting the lightness value or by removing the chrominance values. The luminance-chrominance data is then converted to output space.
