An image processing apparatus and method for generating high-sensitive, high-brightness color images are disclosed. A second image having a wider band and higher-sensitivity than those of a first image which includes color information may be acquired, wherein the first and second images are images captured from a scene. A first transformed image having high brightness may be generated by performing binning on the first image, and edge information being a high-frequency component may be extracted from the second image. A high-brightness, high-sensitive color image may be generated using the first transformed image and the edge information.

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.
