<p>PURPOSE:To prevent a burden from being placed on the eyes of a person who views a screen by displaying a line indicating the break between a current page and a next page slantingly across the screen and changing the pages like paper is turned over by the movement of the slanting line. CONSTITUTION:When a command for starting changing the pages is sent to an MPU from outside, a frame controller 29 selects a frame buffer 2 for a right lower triangular area and a frame buffer 1 for other areas, so the contents of a 2nd page appear in the right lower triangular area and the contents of a 1st page are displayed in other areas. As pages are changed, the frame controller 29 selects the frame buffer 1 only for a left upper triangular area and selects the frame buffer 2 for other areas, so the contents of the 1st page are displayed only in the left upper triangular area and the contents of the 2nd page are displayed in others. When the page changing is finished, the frame controller 29 selects the frame buffer 2 for the entire area of the frame buffer and the contents of the 2nd page are displayed on the entire screen. Consequently, the burden on the eyes of the person who views the screen is reduced.</p> |
