ABSTRACT:
An image display apparatus and a method of providing a high quality image are provided. The image display apparatus includes an image signal processing unit which analyzes an input image signal and outputs an average picture level (APL) and histogram information of one frame; and a controlling unit which calculates contrast control information and average signal level (ASL) information corresponding to the APL and the histogram information. The image signal processing unit enhances the contrast of the input image signal based on the contrast control information output from the controlling unit, and outputs a resulting image signal. Accordingly, a high quality image can be provided to users.
