Abstract: An image display device capable of supporting brightness enhancement and power control and a method thereof, in which the brightness and contrast are enhanced and the power of a light source is controlled in accordance with the image characteristic. In the image display method, a parameter representative of an input image is calculated from a histogram of the input image, a model corresponding to the input image is selected from a plurality of representative models by analyzing the parameter, and then a brightness controlling function matched with the selected model is selected. The size of each component of a pixel constituting the input image is controlled using the brightness controlling function, and the output image of the pixel whose component size has been controlled is displayed.

Abstract: An apparatus and method are provided for correcting a color reproduced by a video device according to peripheral brightness so that the visibility of the video device is guaranteed under peripheral conditions brighter than the video device. The apparatus for correcting a color reproduced by a video device according to peripheral brightness includes: a lookup-table-creation unit which creates a lookup table based on saturation of the video device and brightness of peripheral conditions; a color-correction unit which corrects the color reproduced by the video device according to the created lookup table; and a color-error-compensation unit which compensates for color error resulting from correction of the color. The method of correcting a color reproduced by a video device according to peripheral brightness includes: creating a lookup table based on saturation of the video device and brightness of peripheral conditions; correcting the color reproduced by the video device according to the created lookup table; and compensating for color error resulting from correction of the color.
