Abstract:
1. A display device, comprising: a memory configured to store size information of a display area and an entire image data; a location computing unit configured to compute a start point of a moved display area when the display area is moved; and a display unit configured to decode data corresponding to a size of the display area based on the start point of the moved display area from the entire image data, and to display the decoded data, wherein the location computing unit obtains a center point of the moved display area and sets a point apart from the center point by ½ of the display area each in X and Y directions as the start point, and exchanges a horizontal length value with a vertical length value when a display screen is swung to change an aspect ratio and then sets another point apart from the center point by ½ of the exchanged horizontal length value and ½ of the exchanged vertical length value each in X and Y directions, respectively, as the start point.
