Abstract

PROBLEM TO BE SOLVED: To aid an operator in operation on an input device by cursor movement by displaying video, displayed on a screen where there is an indication display such as a cursor among multiple screens, on a monitor screen. SOLUTION: A cursor position detecting device 101 calculates the movement quantity of the cursor of an input device 104 and determines the display position of the cursor. A cursor display indication device 102 indicates the cursor display on a display board in charge among the display boards 106 to 108 according to the cursor display position. The display board 106 to 108 having received the indication display the cursor at its display position. A monitor switching indication device 103 instructs a switch 120 to connect the outputs of the display board 106 which is displaying the cursor to a monitor display device 121 when the identification number of the display board placed in charge of the cursor display is not the same as the identification number which was stored by the last cursor movement. Then the identification number of the display board placed in charge of the cursor display is stored.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display system for displaying a part of a multi-screen divided display image on a monitor screen by an input for moving an instruction display of an input device in a multi-screen image display system. Things.

[0002]

2. Description of the Related Art Conventionally, when an instruction display such as a cursor is displayed on a multi-screen and an operation such as movement of the instruction display on the screen is performed by an input device, direct visual observation of an image displayed on the multi-screen is performed. Alternatively, the input device has been operated by selecting a part of the image displayed on the multi-screen and viewing the image on the monitor screen displayed by the monitor screen display data converter. When directly viewing an image displayed on the multi-screen, when the size of the multi-screen is increased, it is necessary to display a large instruction display in order to improve the visibility of the instruction display.

On the other hand, when displaying a part of the image displayed on the multi-screen on the monitor screen, it is necessary to select the image displayed on the monitor screen from the display contents of the multi-screen.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to display, on a monitor screen, an image displayed on a screen where an instruction display such as a cursor is present in a multi-screen.

[0005]

Means for detecting an input of a cursor movement of an input device and determining a display position of an instruction display such as a cursor, and a multi-screen for displaying an instruction display are identified. A means for displaying an instruction display with a data converter corresponding to a designated display position on the screen and a display means for displaying a screen on which the instruction display is displayed on the monitor screen among the multi-screens are provided. With the configuration, the image displayed on the screen having the instruction display such as the cursor is displayed on the monitor screen.

[0006]

According to the above-mentioned means, the contents of the screen on which the instruction display is displayed among the multi-screen display images are displayed on the monitor screen by the input for moving the instruction display with the input device, and the instruction of the operator is displayed. Supports display operations.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a multi-screen video display system used to carry out the present invention. In FIG. 1, reference numeral 100 denotes a processing device, which includes a cursor position detecting device 101, a cursor display instructing device 102, a monitor switching instructing device 103, and a plurality of display boards 105 to 108 for converting display data into video signals. The display boards have identification numbers 1 to 4, respectively. 104, an input device; 110, a multi-display device including a plurality of screens for displaying video data as video;
It consists of a screen. Reference numeral 115 denotes a cursor as an instruction display, which is displayed on the multi-screen. A switch 120 selects one output video signal from a plurality of input video data, and has the same input as the video data to the multi-screen. 1
Reference numeral 21 denotes a monitor screen which displays output video data of 120 as video.

FIG. 2 illustrates a method of changing the display content of the monitor screen 121, which is a main part of the present invention. The processing device 100 performs the processing of the flowchart shown in FIG. The cursor position detection device 101 that has detected the cursor movement input by the input device calculates the amount of cursor movement from the input of the cursor movement in the input device, and determines the cursor display position (processing block 201). The cursor display instruction device 102 instructs to display a cursor on a display board in charge based on the cursor display position determined by the cursor position detection device 101 (processing block 202). The display board that has received the instruction displays the cursor at the cursor display position calculated by the cursor position detection device 101 (processing block 203). In processing block 204, the monitor switching instruction device 103 determines whether or not the identification number of the display board that is in charge of displaying the cursor is the same as that stored in the previous cursor movement.

If they are the same, processing block 206 is executed. If they are not the same, processing block 205 instructs switch 120 to connect the output of the display board on which the cursor is displayed to monitor display device 121. The giving processing block 206 is executed. In the processing block 206, the monitor switching instruction device 103 stores the identification number of the display board in charge of displaying the cursor, and ends the processing. As a result, the image of the screen on which the cursor is displayed in the multi-screen is displayed on the monitor display device 121.

[0011]

According to the input of the cursor movement, the contents of the screen on which the cursor is displayed out of the multi-screen display image are displayed on the monitor screen, thereby assisting the operator in operating the input device by moving the cursor.
