Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention temporarily connects information expressed on a display device by connecting it between a computer body and a display device for visualizing the information. The present invention relates to a device that exhibits a function of saving and reusing it. This makes it possible to quickly and simplify the switching operation for displaying the screen to be displayed using the keyboard, coordinate input device (mouse), or the like.

[Prior Art] Conventionally, in the case of using one display device, simply (normally) with respect to an output signal from the computer main body side.
A function of displaying contents or storing / reproducing some input signals in a display device has been devised. (Actual exploitation 62
-71687) [Problems to be solved by the invention] When the computer main body and the display device are connected and used, the image signal sent from the computer side is usually attached to one display device as a keyboard or the display device. The target image was selected and the information was obtained by operating the switch or the like. For an image that changes with the passage of time, in order to reproduce an arbitrary one-frame (one-screen) image, it is necessary to use a keypad of a large number of steps or a display device having a storage / playback function. .

In addition, the conventional technique has a drawback that only one screen can handle a small amount of information such as one screen and a drawback that complicated operations are required for image reproduction.

[Means for Solving the Problem] The present invention, which is different from the above-mentioned prior art, is located between a computer body and a display device, distributes an arbitrary image signal output from the computer, and normally outputs the image signal. By providing a circuit, a circuit for normally outputting an image signal, a circuit for storing and reproducing one or more frames of an arbitrary image, a circuit for synthesizing a plurality of image signals, and a circuit for controlling these, a switch (including a remote controller switch) ) Or a control signal from the computer side (which can also be controlled by software), the screen is switched and multiple images (usually different images) are displayed on multiple display devices at the same time so that a large amount of screen information can be displayed at once. Therefore, it is easy to compare screens, and the correlation can be easily obtained. It should be noted that it is also possible to display images (normal images, stored / reproduced images, and combined images) that are desired to be displayed in the same (one) display device by overlapping and combining or arbitrarily dividing the screen.

First Embodiment Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. The input signal distribution 1 has a function of distributing the image signal from the computer main body side to the control 5, the storage / recording 2, the screen division / synthesis 4, and the output terminal B while matching the image signal. Storage / recording 2 is controlled by control 5 by input signal distribution 1 and screen division /
Storing / recording the signal from composite 4 and playing it back under control of control 3
It has a function to output to. The reproduction 3 has a function of outputting to the screen division / composition 4 or the output terminal A according to the control signal of the control 5. The screen division / combination 4 has a function of combining the signals of the reproduction 3 and the input signal distribution 1 under the control of the control 5 and displaying the screen by arbitrarily dividing the screen. The control 5 has a function of controlling each function and connecting the signal from the input signal distribution 1 to the output terminal A. The output terminal A is connected to the display device DA. The output terminal B is connected to the second display device DB. The above function is not affected even when the display device is not connected to the output terminal B.

[Embodiment 2] FIG. 2 is a diagram in which a function for controlling each function by an external control signal or an external switch (such as a remote control switch) is added to the control 5 in FIG.

[Embodiment 3] FIG. 3 shows that the video printer VP can be connected to the function shown in FIG.

[Embodiment 4] FIG. 4 is an embodiment in which the function of FIG. 1 is connected to a large number of display devices for use.

[Effect of the Invention] A circuit connected between a computer and a display device to distribute an arbitrary image signal output from the computer and output a normal image signal, a circuit which normally outputs an image signal, and an arbitrary image By providing a circuit for storing and reproducing one or more frames, a circuit for synthesizing a plurality of image signals, and a circuit for controlling these, a switch (including a remote control switch) and a control signal from the computer side (also controlled by software) You can obtain a large amount of screen information at once by displaying multiple images (usually different images) on multiple display devices at the same time, making it easy to compare screens at the same time. It is possible to obtain the correlation easily. In addition, the switching operation for displaying the screen to be displayed by the keyboard or the coordinate input device (mouse) can be quickly and simplified. The same (1
It is also possible to display images (normal images, stored / reproduced images, and composite images) that are desired to be displayed in a display device in a duplicated manner or in a composite manner or by arbitrarily dividing the screen.
