<P>PROBLEM TO BE SOLVED: To efficiently browse the past display screens. <P>SOLUTION: When contact position coordinates or approach position coordinates are detected, an image display device renders a drawn image drawn on the basis of the detected contact position coordinates or the approach position coordinates on video information displayed in a display area on a superposed manner. Also, the image display device switches between a first state which renders the drawn image in the superposed manner when the contact position coordinates or the approach position coordinates are detected, and a second state which does not render the drawn image in the superposed manner even when the coordinates are detected. In the first state, the image display device stores first image information for reproducing an image displayed in the display area, in a storage device by arbitrary timing. In the second state, when the contact position coordinates or the approach position coordinates are detected, the image display device stores second image information for reproducing the image displayed in the display area in association with the first image information stored by a first storage unit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
