Further, by directly designating the screen of the touch sensor input television device 8e with a finger, data corresponding to the set position is set.

In step 2, the image selection input section 7
Judges whether the information set by the setting device is position information. If it is position information, the process proceeds to step 3, and if not, the process proceeds to step 4.

In step 3, when the position information is input and set, the position determination processing routine is called. Then, in step 3a, the input position information for the video selection 7 is the same as the internal position information (for example, the position information is the area number and the position information in the input unit 7 for video selection is the same). Area number) that does not require conversion or that needs to be converted into internal position information (for example, the position information is the area number and the position information in the image selection input section 7 is the latitude). And longitude)
If it is necessary to convert, the process proceeds to step 3b. If no conversion is required, the process proceeds to step 3c. In step 3b, the video selection input section 7 converts the positional information into the internal format using the mapping data of the conversion table, and proceeds to step 3c. In step 3c, the video selection input unit 7 stores the converted or non-converted position information in the storage area, and proceeds to step 8.

In step 4, the video selection input section 7

In step 5, when the distance information is input and set, the distance determination processing routine is called. Then, in step 5a, it is judged whether or not the setting device input and set in the video selection input section 7 is for ten key input, and if input is set for ten key input, the process proceeds to step 5h. If the input for ten-key input is not set (in the case of the arrow input setting device 8b), the process proceeds to step 5b. In step 5b, the image selection input section 7 extracts the current distance information initially or previously stored in the storage area, and proceeds to step 5c. Step 5c

In step 5d, the image selection input unit 7 determines whether or not the downward arrow key of the arrow input setting device 8b is pressed (away from the subject by pressing), and if it is pressed, step 5e. Go to step 5f if not pressed. In step 5e, the video selection input unit 7 adds the current distance value stored in the storage area and the moving distance value obtained based on the above arithmetic expression to calculate the current distance, and Go to 5g. In step 5f, the video selection input unit 7 determines that the upward arrow key has been pressed (approaching the subject by pressing the key), and based on the current distance value stored in the storage area and the arithmetic expression. The value of the difference from the obtained moving distance value is calculated as the current distance value, and the process proceeds to step 5g. In step 5g, the video selection input unit 7 stores the calculated current distance value in the storage area, and proceeds to step 8. At step 5h, the image selection input section 7 is operated by the ten-key input setting device 8.
The distance information set in a is stored in the storage area and the process proceeds to step 8.

In step 6, the video selection input section 7
Judges whether the object information has been input. If the object information has been input, the process proceeds to step 7. If the object information has not been input, the process returns to step 1.

In step 7, when the object information is input and set, the object determination processing routine is called.
The display area based on the object information displays a partial area (xy area) of the display area (XY area) of the display unit 9 as shown in FIG. 7A. Then, in step 7a, the image selection input section 7 obtains the coordinate position of the origin A (X1, Y1) of the display image currently displayed on the display section 9 and proceeds to step 7b (FIG. 7 (b)). reference). Step 7b
At this point, the image selection input section 7 obtains a point a (x1, y1) of the object information inputted from the setting device, and the obtained point a and the origin A are calculated by the equation (X = X1 + x1− x /
2, Y = Y1 + y1−y / 2), the moving point A2 is calculated to obtain the position of each display image, and the process proceeds to step 7c (FIG. 7).
(See (b)). In step 7c, the video selection input section stores the calculated positions of the respective display videos in the storage area, and the process proceeds to step 8.

In step 8, the image selection input section 7
Determines whether the setting information is still present. If the setting information is present, the process returns to step 1, and if the setting information is not present, the process ends. Next, position information set via the setting device,
The operation of selecting and processing the video signal based on the distance information and the object information will be described.

In step 100, the video selection processing section 8 sets the information (positional information, information set in the video selection input section 7).

The position information processing unit of the video selection processing unit 8 converts the set position information into the number N of the television camera by the mapping data of the data conversion table, and proceeds to step 101b.

In step 101b, the position information processing section takes out the Nth video signal from the video signals multiplexed based on the converted TV camera number N and returns.

In step 101c, when selecting a video signal corresponding to the set position information from the video signal group in which the number of the television camera is added as the additional information, the video selection processing section 8 is selected. The position information processing unit of No. 2 converts the set position information into the number N of the television camera by the mapping data of the data conversion table, and proceeds to step 101d.

In step 101d, the position information processing unit searches for a video signal corresponding to the added number data N from the video signal group multiplexed based on the converted number N of the television camera. Take it out and return.

In step 101e, position information indicating the azimuth position with respect to the subject and distance information indicating the distance from the subject to the television camera are added as additional information, and the above-mentioned setting is performed from the multiplexed video signal group. When the video corresponding to the position information is selected, the position information processing unit of the video selection processing unit 8 has the same position information from the multiplexed video signal group based on the set position information. Search for the signal, take out and return. The extracted video signal is output to the display unit 9 only when the position information is set.

In step 102, the distance information processing unit of the image selection processing unit 8 processes one selected video signal from the position information processing unit based on the set distance information, and the processing process is performed. The output video signal is output.

First, in step 102a, the additional information is a non-added video signal or a video signal multiplexed with the television camera number added as the additional information, and the positional information and the distance information are both transmitted through the setting device. When set, the distance information processing unit of the video selection processing unit 8 uses the number N of the TV cameras obtained by the position information processing as a data conversion table (from the subject corresponding to each TV camera number to each TV camera). The distance D to the subject is obtained by (the distance is predetermined), and the process proceeds to step 102b.

In step 102b, the distance information processing unit enlarges or reduces one image signal selected by the position information processing unit based on the distance D and the distance information input and set via the setting device. Displayed video signal 9

In step 102d, the distance information processing unit enlarges or reduces the video signal selected by the position information processing unit based on the fetched distance information and the input and set distance information. Output to the display unit 9 and return.

Further, in step 103, the multiplexed video signal is added with position information and distance information as additional information, and the position information, distance information and object information are set through the setting device. In this case, the object information processing unit of the video selection processing unit 8 limits the display of the video signal selected and processed by the position information processing unit and the distance information processing unit.

In step 103a, the object information processing unit of the image selection processing unit 8 receives the image signal enlarged or reduced by the distance information processing unit based on the object information input and set through the setting device. Then, the video signal displayed in the display video area whose display is limited is output and the process returns.
