  • Apparatus using ambient light as backlight and method for correcting colors therein
    Patent number: 8059084
    Abstract: Provided are an apparatus using ambient light as backlight and a method for correcting colors in the apparatus. The apparatus includes a color correction matrix generator and a color corrector. The color correction matrix generator generates a first color correction matrix for correcting a second color conversion matrix when ambient light is used as backlight into a third color conversion matrix for the original backlight. The color corrector corrects colors using the first color correction matrix.

  • METHOD OF TRANSMITTING COLOR GAMUT INFORMATION AND IMAGE DEVICE USING THE SAME
    Publication number: 20080129861
    Abstract: A method of transmitting color gamut information and an image device using the same are provided. The image device includes a color gamut information generating unit which generates color gamut information; an ancillary data generating unit which generates ancillary data including the color gamut information; and a composition unit which combines the ancillary data and image data. Since the image device reproduces an image based on the color gamut information, the quality deterioration of the image may be prevented.
