Image display apparatus for controlling luminance and the luminance controlling method thereof
First Claim
1. An image display apparatus comprising:
- a luminance sensor which measures a surrounding luminance;
a luminance change sensor which senses a change of the surrounding luminance based on the measured surrounding luminance;
a luminance energy comparator which compares the sensed change of the surrounding luminance with a preset threshold; and
a luminance adjustment controller which adjusts a luminance of a display according to an eye adaptation using a result of the comparison of the sensed change of the surrounding luminance with the preset threshold by the luminance energy comparator.

Abstract
An image display apparatus capable of controlling a luminance and a luminance controlling method are provided. The image display apparatus includes a luminance sensor to measure a surrounding luminance, a luminance change sensor to sense a change of the surrounding luminance using the measured surrounding luminance, a luminance energy comparator to compare the sensed change of the surrounding luminance with a preset threshold and to compare a maximal eye adaptation in the measured surrounding luminance with a maximal luminance energy of a display, and a luminance adjustment controller to adjust a luminance of the display according to the eye adaptation using the comparison result of the luminance energy comparator.
