IMAGE DISPLAY APPARATUS
First Claim
1. An image display apparatus that displays an image on a display unit based on image data, comprising:
- a region division unit that divides a display surface of the display unit into a plurality of regions;
a degree-of-influence calculation unit that calculates a first degree of influence representing a degree of influence of a brightness level of each of the regions on a brightness level of a respective region adjacent to the region, the regions resulting from the division by the region division unit; and
a brightness correction unit that corrects a brightness level of each of pixels in the image data based on the first degree of influence,wherein influence of not only a location of connection in wiring in the display unit with an input terminal of a power supply for the display unit but also a wiring configuration of the display unit is reflected on the first degree of influence,wherein the region division unit includes;
a brightness-level-total calculation unit that calculates totals of brightness levels of the pixels, the totals being calculated for respective lines of the pixels on the display surface; and
a difference calculation unit that calculates differences in the totals of the brightness levels between mutually adjacent lines of the pixels, andwherein the region division unit selects a difference that is more than or equal to a first threshold and the number of which is not more than a predetermined number from a highest difference among the differences calculated by the difference calculation unit, and the region division unit sets a border between the lines of the pixels corresponding to the selected difference to a border for the division.

Abstract
An image display apparatus includes: a region division unit that divides a display surface into a plurality of regions; a degree-of-influence calculation unit that calculates a first degree of influence representing a degree of influence of a brightness level of each of the regions on a brightness level of a respective region adjacent to the region; and a brightness correction unit that corrects a brightness level of each pixel. Influence of not only a location of connection in wiring in a display unit with an input terminal of a power supply for the display unit but also a wiring configuration of the display unit is reflected on the first degree of influence.
