摘要： 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.

摘要： An apparatus and method for improving visibility of an image. The apparatus includes: a lookup table (LUT) generating module generating an LUT having image data in a high illuminance environment corresponding to image data of an input image set therein so as to increase lightness and chroma of the input image according to external illuminance; an image mapping module mapping the image data of the input image into the image data in the high illuminance environment on the basis of the generated LUT; and a local contrast increasing module increasing local contrast of the mapped image data using a parameter for adjusting the local contrast according to the external illuminance.
