<p>A display system is provided, which makes it possible to switch automatically from a single image mode to a dual image mode, and vice versa, without input of any switching signal. When an image is displayed on the screen of the display device the single image mode according to the first video input sent through the first input line, the first detector outputs the first detection signal. Thereafter, if the second detector detects the synchronizing signal of the second video input sent thorough the second input line, the second detector outputs the second detection signal. This means that the switch receives both of the first and second detection signals in this state. As a result, the switch selects the dual image mode and accordingly, a the two images are simultaneously displayed on the screen of the display device. <IMAGE></p> |
