<p><P>PROBLEM TO BE SOLVED: To efficiently refer to corrected contents later by efficiently storing overwrite contents. <P>SOLUTION: A display device 1401 is provided which includes a display screen, a coordinate input device, coordinate detection means which detects coordinates of a point designated by the coordinate input device, and overwrite means which opens a transparent window represented in the same color as that of an area on each of areas displayed on the display screen and displays an image based on the coordinates detected on the transparent window by the coordinate detection means as an overwrite image on the transparent window. The display device 1401 further includes monitor means 313 which monitors a change in a background image displayed on the display screen, alert means 315 which displays a message for determining whether to store a combination image of the background image and the overwrite image when the change in the background image is detected by the monitor means, and storage means 305 which stores the combination image if it is inputted from the coordinate input device to store the combination image. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
