This composite output image is displayed and confirmed on the monitor 7. Synthesis control processed inside the image synthesizer 10,
That is, the adjustment of the size, position and display priority of the display window of each image is performed via the control signal line 12.
It can be performed by the computer 6.

The operator operates using the operation input section 8 and the monitor 7 connected to the computer 6. Each operation command input from the operation input unit 8 is processed by the computer 6, converted into a control command corresponding to the input, and then transmitted to the camera platform 2 via the control signal line 4. The camera 1 and the platform 2 execute the processing corresponding to the item of the received control command, and return the information of the control state to the computer 6 also via the control signal line 4. The returned status information is processed inside the computer 6, and the result is reflected on a part of the computer screen corresponding to the item that was previously operated and input, and is sent to the video synthesizing device 10 as an image output signal, and finally. Is displayed on the screen of the monitor 7. Further, the image synthesizing device 10 constantly synthesizes the control computer image from the computer 6 and the image captured by the camera, and the synthesized output is displayed on the monitor 7 in real time.

An example of a composite screen of the monitor 7 for confirming these operations is shown in FIG. In the example of FIG. 2, the control computer image is represented as the background (priority = low), and the camera-captured image is represented as the foreground (priority = high). In FIG. 2, reference numeral 71 denotes a display frame for a control computer image, and 72 denotes a display frame for a camera-captured image. The contents of each image and video are displayed in the area inside the display frames 71 and 72. Reference numeral 73 is a cursor. The size and position of the display frames 71, 72,
The computer 6 can control the priority and the like externally. A video moving image output from the camera 1 is constantly displayed inside the display frame 72 of the image captured by the camera.
Inside the computer image display frame 71 outside the area of the display frame 72, the above various items required for camera control are displayed.

A specific operation / confirmation procedure in FIG. 2 will be described below. The cursor 73 shown in the figure is
The inside of the display frame 71 can be moved by operating the operation input unit 8 connected to the computer 6. The operator
First, after moving the cursor 73 into the area in which the item to be controlled is displayed, an operation input for giving an instruction is performed. For example, in order to operate the wiper of the camera 1, after moving the cursor 73 to the "wiper""ON" area of the screen of FIG. Click). As a result of this operation,
The instruction is transmitted to the camera platform 2 in a predetermined procedure, and the wiper (not shown) attached to the camera 1 operates.
The status information is returned from the camera platform 2 and processed by the computer 6, and the colors of the "wiper" and "ON" areas on the screen of FIG. 2 change and are confirmed by the operator.

Similarly, when controlling the horizontal angle of the camera 1, "right" of the "pan" area on the screen of FIG.
An input operation is performed by moving the cursor 73 to any of the "left" areas. As a result of this operation, the instruction is transmitted to the camera platform 2 in a predetermined procedure, the horizontal angle of the camera platform 2 is changed, and the position information is sequentially returned from the camera platform 2 to the computer 6.
At this time, on the screen of FIG. 2, an arrow indicating the camera position inside the area displaying the current horizontal angular position of the camera 1 is displayed.
It is rotated and displayed in the right or left direction corresponding to the above-mentioned returned position information, and is confirmed by the operator. In any of the above cases, since the camera image captured by the camera 1 is constantly displayed in the display frame 72, the operator can confirm the image on the same screen.

In the example of FIG. 2, it is assumed that the display frame 72 is always displayed. However, when it is not necessary to display the camera image for the operation confirmation work, the entire display frame 72 is displayed. It is also possible to control the computer 6 via the control signal line 12 by eliminating the above (closing the window) and making the screen entirely the display frame 71. Further, the arrangement of each control item area in FIG. 2 can be easily changed by software of the computer 6 other than the illustrated arrangement. Furthermore, for horizontal / vertical angle position display, it is possible to easily display the position itself as numerical values other than the method shown in FIG. 2 with software, and to change the color of the operation screen inside the display frame 71. The same applies to methods and the like.
