Abstract
Image signals input terminals are selected by a selector. The image signals are combined and displayed on the same screen of a display device. The display screen includes one main screen and a plurality of sub screens. In the case where a moving image is displayed on the main screen, images displayed on the sub screens are updated when the moving image displayed on the main screen are in a still state. The modes of the image signals are detected only when they are input for the first time, the process performed upon the image signals input after that is controlled in accordance with information stored in a memory.
Claims36
An image display device comprising:
- a plurality of input terminals for inputting a plurality of image signals, respectively;
- and
- combining and displaying means for combining said plurality of image signals input via the input terminals and displaying the resultant image on the same screen of a display device.
A method of controlling an image display device, comprising the steps of:
- inputting a plurality of image signals via a plurality of input terminals;
- and
- displaying the plurality of input image signals on the same screen of the display device.
A storage medium including a computer-executable program stored thereon, said program including a process of controlling an image display device, said process comprising the steps of:
- inputting a plurality of image signals via a plurality of input terminals;
- and
- displaying the plurality of input image signals on the same screen of the display device.
A storage medium including a computer-executable program stored thereon, said program including a process of controlling an image display device, said process comprising the steps of:
- determining one of said plurality of terminal devices as a master terminal device and the remaining terminal devices as slave terminal devices;
- and
- employing an image signal, transmitted from the terminal device determined in said determination step as the master terminal device, as a main image selected from image signals which are combined and displayed on the same screen of said display device.
