  • Patent number: 9495730
    Abstract: A display device to change an image displayed in a display area when the display area is changed includes a memory, a location output unit and a screen display unit. The memory stores size information of a display area displayed on a screen and the image data of the displayed image. The location computing unit computes a start point of the changed display area when the display area is changed. The display unit decodes data corresponding to the size of the display area based on the computed new start point from the image data to display the decoded data in the display area. Since the start point is obtained with center point of the changed display area and its size information and then a display area to be displayed is determined based on the start point, a current search location is maintained even when the screen is swung.
