An amplifier 22 is provided, and the parameter calculation unit 19 determines the operation parameters of all the regions by using at least two operation parameters, that is, values of pan, tilt, zoom (magnification), and focus (focal length). Can be calculated. The RAM 20 stores the parameters of the shot operation corresponding to each shot number of the touch input unit 12, and when the parameters are calculated by the parameter calculation unit 19, the parameters are stored. The above-described parameter setting of the shot operation can be automatically performed for all areas by setting two points in the diagonal direction of the touch input unit 12. That is, as shown in FIG. 3, the touch panel 11 is assigned coordinates of 0 to 255 for pan (X coordinate) and tilt (Y coordinate), for example, corresponding to the imaging area. The point at which this occurs is the shot position.
For example, the parameter of the center position is the coordinates (128, 12

By setting (0, 2 [magnification], 3 [m]), the parameter calculation unit 19 calculates the operation parameters of the shot numbers of the entire area, and these parameters are stored in the RAM 20. After setting the parameters, the parameters can be individually reset by operating the joysticks 15A and 15B and the switch 16. The amplifier 22 is connected to a pan head driving unit 23 disposed in the pan head 4 and a lens driving unit 24 disposed in the lens unit 1. The control signal for the shot operation is supplied to the lens drive unit 24 based on the parameters read from the RAM 20 by the CPU 18. The embodiment has the above configuration, and the CPU
18 performs the operation shown in FIGS.
First, FIG. 4 shows an automatic setting operation of the shot operation parameter. When the automatic setting button 16A is pressed in step 91, it is determined in step 92 whether or not the automatic setting button 16A is pressed. The process proceeds to step 93. Then, in step 93, two points (2

For example, when the shot number C6 is selected, the shot number C6 portion is arranged at the center of the screen as in the screen of the monitor 10B shown in FIG. The shot image having the magnification calculated by the parameter calculator 19 is photographed and displayed. When a different shot number is selected by the touch input unit 12, the selected shot image is displayed on the screen of the monitor 10B instead of the image of the shot number C6. The image can be returned to the basic image by the reset button 16B of the unit 14. In the above embodiment, the case where the parameters are set at two points in the diagonal direction has been described. However, by setting the parameters of two points in the vertical direction or two points in the horizontal direction, four points in the vertical and horizontal directions are set. Thus, the parameters of the whole area may be set. In the above-described embodiment, the case where the photographing is performed by the two sets of the television camera system has been described. However, the basic image and the shot image are switched only by the one set of the television camera 2, the camera platform 4, and the monitor 10. You can also shoot. Further, in the above embodiment, the touch input section 12 of the touch panel 11 is divided into 64 pieces.
