Embodiment Construction

[0079] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. Figure 4 A usage form of an example of the monitoring device 1 according to the first embodiment is schematically shown. Two computer devices 2A and 2B are connected to the monitoring device 1 . In addition, in the following description, it is assumed that the computer device is a personal computer (abbreviated as Pasocon in Japan). Video signals 4A and 4B output from the personal computers 2A and 2B are supplied to the monitoring device 1, respectively. The monitor device 1 can display the video signals 4A and 4B on the display areas 7A and 7B of the display unit 6, respectively.

[0080] In addition, by connecting the keyboard 3 and the mouse 14 to the monitoring device 1 as input devices, the keyboard 3 and the mouse 14 can be shared by the two personal computers 2A and 2B. That is, the key information 10 output from the keyboard 3, and the mouse movement am...

Abstract

A picture display device displays a video signal supplied from a data process device. Bi-directional communication is carried out with each of a plurality of data process devices. A plurality of video signals is combined into one screen corresponding to information of the picture size of each of the plurality of video signals obtained by the bi-directional communication with each of the plurality of data process devices. A video signal, outputted when the plurality of video signals is combined, is displayed. A second control signal is generated which controls the plurality of data process devices and which corresponds to a first control signal that corresponds to a user operation. The first control signal and the second control signal are transmitted to the plurality of data process devices. The plurality of data process devices also communicate bi-directionally with each other.

Description

[0001] This application is a divisional application of: [0002] Title of Invention: Image Display Device and Method [0003] Application date: January 10, 2001 [0004] Application number: 01800496.2 (PCT / JP01 / 00058) technical field [0005] The present invention relates to an image display device capable of connecting multiple computer devices, displaying the display screens of the connected multiple computer devices on one screen, and simultaneously controlling the connected multiple computer devices by a common input device. method. Background technique [0006] Computer devices are mostly connected to external monitoring devices and input devices such as keyboards and mice when they are used. The user performs data processing of the application software by operating the input device based on the display of the monitoring device. [0007] Depending on the content of processing and the needs of users, it may be desirable to activate and operate a plurality of computer...
