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.

This application claims priority from Korean Patent Application No. 10-2006-0075382, filed on Aug. 9, 2006 in the Korean Intellectual Property Office, the entire disclosure of which is hereby incorporated by reference.
1. Field of the Invention
Apparatuses and methods consistent with the present invention relate to an image display apparatus and a method of providing a high quality image, and more particularly, to an image display apparatus which analyzes characteristics of an input image signal and dynamically processes the signal based on the analysis to provide a high quality image display.
The above and other aspects of the present invention will be more apparent from the following description of exemplary embodiments, taken in conjunction with the accompanying drawings, in which:
FIG. 1 illustrates a method of displaying of a related art image display apparatus;
FIG. 2 is a graphical representation of the number of sustain pulses of a related art image display apparatus as a function of the APL;
The matters defined in the description, such as a detailed construction and elements, are provided to assist in a comprehensive understanding of exemplary embodiments of the invention. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the exemplary embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness. Throughout the drawings, the same reference numerals will be understood to refer to the same elements, features, and structures.
FIG. 4 is a block diagram of an image display apparatus based on an exemplary embodiment of the present invention.
Referring to FIG. 4, the image display apparatus 100 based on an exemplary embodiment of the present invention includes an image signal processing unit 110, a main controlling unit 130, and a display unit 150.
