Abstract
The present disclosure relates to an image display apparatus. The image display apparatus includes: a display; and a controller configured to control the display, wherein the controller detects a first peak area corresponding to a luminance value greater than or equal to a first reference value, and a second peak area corresponding to a luminance value between the first reference value and a second reference value less than the first reference value, in response to the number of pixels in the second peak area being less than or equal to a predetermined number, the controller performs first tone mapping based on the first peak area, the controller performs second tone mapping based on the first peak are and the second peak area, wherein a luminance value of the second peak area during the second tone mapping is greater than a luminance value of the second peak area during the first tone mapping. Accordingly, luminance and contrast during displaying image may be improved.
