A mode-changeover device is provided for enabling observers' eyes to easily follow a display video image during the change of its display magnification. In a mode-changeover device (1), a plurality of first magnifications are allocated in advance to either one of the horizontal direction and the vertical direction of a video image while a plurality of second magnifications are allocated in advance to the other. Whenever an observer operates, a CPU (151) in the mode-changeover device (1) selects the second magnifications one by one with either one of the first magnifications fixedly selected and then selects the second magnifications one by one with another one of the first magnifications fixedly selected. Further, whenever the CPU (151) selects the first and second magnifications, a video image processing circuit (12) magnifies the input video image in accordance with the selected magnifications. A screen (13) displays the video image magnified by the video image processing circuit (12). |
