PROBLEM TO BE SOLVED: To reflect a touch input result on a large screen of a multi-display while allowing a touch input on a small screen constituting the multi-display.SOLUTION: When a video output device 20 receives touch coordinate data, an additional image 1002 newly drawn by a touch pen 30 of a display 13 with a touch panel is reflected as an additional image 2001 to an image 2000 output from the video output device 20. Subsequently, a touch panel control unit of the video output device 20 outputs the image 2000 output from the video output device 20 via a video output cable 42 to a multi-display 10. As a result, an additional image 1003 to which the additional image 1002 of the display 13 with the touch panel is reflected is displayed on the entire large screen of the multi-display 10.SELECTED DRAWING: Figure 12 |
