In this case, a signal proportional to, for example, the pressure of the touch input unit pressed with a finger is input from the touch panel, and the zoom magnification is calculated by this signal, and the zoom output of the TV camera lens unit is calculated by this calculation output. Done.

[0009]

FIG. 1 shows the configuration of a television camera operation control device using a platform according to the embodiment, and FIG. 2 shows the circuit configuration thereof. In FIG. 1, a television camera 2 having a lens unit 1 is attached to a platform 4 supported by a column 3, as in the conventional case. The platform 4 allows the television camera 2 to pan (horizontal direction) and tilt (horizontal direction). (Up and down direction)
It can be driven to rotate. A monitor 10 for inputting a video signal and displaying a captured image is connected to the television camera 2, and a touch panel 11 is attached on the screen of the monitor 10 so as to overlap the entire screen.

The touch panel 11 is made of a transparent material and has a plurality of touch input sections 12 set in a matrix. Each of the capacitance type, surface acoustic wave type, resistive film type, infrared type, etc. The system type can be applied. For example, in the case of the electrostatic capacitance method, the contact state with the panel surface can be detected by the change of the electrostatic capacitance, and the contact position can be detected by the fluctuation of the minute AC (alternating current) current (signal) supplied to the touch panel 11. Then, the contact position is output as the information of the XY coordinate data, whereby each position of the touch input unit 12 is identified. In the embodiment, the touch panel 11 is vertically and horizontally divided into eight (otherwise 16 or the like may be used), so that 64 touch input units 12 are formed on the entire screen.

In addition, the touch panel 11 can take out the pressed state of the panel as a Z-axis signal, and electrically changes the thickness of the inter-electrode layers arranged on the front surface layer and the back surface layer of the panel by the pressing. By taking it out, the pressing force can be detected. In the embodiment, this change in pressing is detected in the range of 0 to 255 (Z value), and the zoom magnification is calculated by this pressing signal. A detection signal of the contact time of the touch input unit 12 can be used instead of the pressing signal.

An operation control unit 14 is provided so as to be connected to the lens unit 1 and the platform 4 of the television camera 2.
The touch panel 11 of the monitor 10 is the operation control unit 1
4 is connected. The operation control unit 14 has a joystick 15A for pan / tilt movement and a joystick 15B for zooming and focusing. The joysticks 15A, 15B independently operate the platform 4 and the TV camera 2. be able to.
Therefore, it is possible to actually operate the lens unit 1 to an arbitrary position and set each parameter of the operation. Also,
Although the reset button 16A is provided on the upper left portion of the operation control unit 14, the reset button 16A can be attached to the monitor 10 side.

As shown in FIG. 2, the touch panel 11 has, for example, A to H (Y axis 0 to 255) in the vertical axis direction,
If 1 to 8 (X axis 0 to 255) is assigned to the horizontal axis direction,
The touch input section 12 having the frame numbers (identification numbers obtained from the coordinate data) A1, A2 ... H7, H8 is set. In addition to the joystick 15 and the switch 16, the operation controller 14 includes an interface 17, a CPU (central processing unit) 18, and a CPU.
A magnification calculation and P (pan) / T (tilt) calculation unit 19, a read-only memory (ROM) 20, a D / A converter 21, and an amplifier 22 which are set in 18 are provided. Data of the zoom ratio corresponding to the zoom position is stored.

Further, the above-mentioned magnification calculation and P / T calculation unit 19
First calculates the pan and tilt and the zoom magnification based on the pressing signal from the touch input unit 12, and when the pressing is low, the low magnification is high, and when the pressing is high, the pressing is high. Magnification data proportional to the signal is calculated and output. In the embodiment, the photographing operation can be redone even on the screen in the middle of the zoom photographing operation on the touch panel 11. For this purpose, the pan and tilt correction coefficients are read from the ROM 20 and the arithmetic unit 1 is operated.
Correction calculation is performed in 9.

That is, as shown in FIG. 3, the touch panel 11 is assigned coordinates 0 to 255 for the pan (X coordinate) and the tilt (Y coordinate), respectively, corresponding to the photographing area. The point with the coordinate as a parameter is the shooting position. For example, the parameter of the center position is indicated by coordinates (128,128). In this figure (a), although the target object is present at the point P1 of the coordinates (X1, Y1), the coordinates (X2, Y2
) When the frame number C3 including the point P2 is selected by the touch input unit 12 and operated by a predetermined press,
As shown in the figure (b), the point P2 of the coordinates (X2, Y2) moves to the center point Q2 of the coordinates (X3, Y3), and the target object changes to the point Q1 of the coordinates (X4, Y4). It will shift. Therefore, when the frame number C7 including the point Q1 is pressed again in the state of FIG. 7B, it is necessary to perform the calculation for replacing the distance between Q1 and Q2 with the distance between P1 and P2 in FIG. This calculation is executed by the P / T calculator 19.

Further, a pan head driving unit 23 arranged in the pan head 4 and a lens driving unit 24 arranged in the lens unit 1 are connected to the amplifier 22, and these pan head driving units 23 are connected. The lens drive unit 24 is supplied with a control signal for operation based on the parameters read from the ROM 20 by the CPU 18.

The embodiment is configured as described above, and the platform position is calculated by pushing the touch input unit 12 of the touch panel 11, but in FIG. 1, the frame number G6 is selected and the touch input unit 12 is selected. When is pressed a little strongly, as shown on the monitor 10S, an image in which the hut which is the target is enlarged is displayed. That is, the CPU 18 of FIG. 2 detects the frame number G6 from the touch panel 11 and calculates the pan / tilt position corresponding to the frame number G6 by the calculation unit 19. Based on the pan / tilt information, the pan / tilt head is detected. When the drive unit 23 is controlled, the hut moves to the center of the screen.

The pressing signal of the touch input section 12 is CP
It is supplied to U18, and in this CPU 18, the calculation value of the zoom magnification based on the pressing signal is calculated by the magnification calculation and P / T calculation unit 19. Then, the lens driving unit 24 is controlled by the zoom magnification control signal, and thereby zooming is executed. Here, if it is enlarged too much, the enlargement ratio can be reduced by pushing again with a force smaller than the previous time, while if the enlargement is insufficient, by pushing again with a large force, The enlargement ratio can be increased. In the above case, it is necessary to focus the image, but by providing the lens unit 1 with an autofocus function, the focus can be automatically adjusted.

FIG. 4 shows C when the operation is reset.
The operation centering on the PU 18 is shown, and FIG. 5 shows the image display state at that time. In FIG. 4, zoom position data from the lens unit 1 is C at step 101.
Data of the zoom ratio (focal length) stored in the ROM 20 is read from the position data supplied to the PU 18 (step 102), and the process proceeds to step 103.
In this step 103, the horizontal and vertical angle of view (coordinate range) is calculated, and then the ratio (R) to the pan and tilt operation angle (amount) is obtained (step 10).
4) and shifts to step 107. Also, step 10
At 5, the current pan and tilt positions are detected based on the control signal to the platform 4 or the feedback signal from the platform 4, and the process proceeds to step 107. On the other hand, in the touch panel 11, the position (X-axis, Y-axis) signal and the press (Z-axis) signal re-input by the touch input unit 12 in step 106 are input to the CPU 18, and these signals are used for the above magnification calculation and The data is supplied to the P / T calculation unit 19, and the process proceeds to step 107.

In step 107, the pan / tilt control amount for the re-input position is calculated in the magnification calculation / P / T calculation section 19, and a new zoom magnification is calculated. Then, next step 1
At 08, the platform 4 is driven to the left, right, up and down based on the calculated pan and tilt control amounts, and step 10
At 9, the lens is driven by the zoom magnification to enlarge or reduce the subject. In this zoom control, the enlargement ratio is determined by the pressing signal for each input of the touch input unit 12 as described above, and therefore, when the pressing force is lighter than the previous pressing, the enlargement ratio is reduced. In addition,
When the magnification is converted by re-inputting, the touch input unit 12 at the center of the touch panel 11 is pressed.

In the example shown in FIG. 5, when an attempt is made to magnify an image of the gondola of the balloon indicated by P1 in FIG. 5A, if a position deviated from the position P1 as shown in the figure is pushed for some reason, As shown in Fig. (B), the gondola will be further away from the center when it is enlarged. However, in the embodiment, since the photographing operation is corrected by pressing the position of Q1 again in the state of this figure (b), it is possible to obtain the image of the figure (c) in which the gondola is arranged in the center of the screen. Become.

Further, when the balloon is moving in FIG. 5, it is possible to capture the moving balloon by pressing each touch input section 12 of the touch panel 11 and sliding the balloon in the moving direction. As described above, in the embodiment, it is possible to easily obtain the next captured image by inputting again the previous captured image. When returning to the basic image, the reset button 16A of the operation control unit 14 may be pressed.

In the above embodiment, the zoom magnification setting control is performed by the pressing signal of the touch input section 12, but
This can be controlled by the pressing time of the touch input unit 12, and in this case, for example, the CPU 18 detects the pressing time and calculates the magnification corresponding to the pressing time to control the setting of the magnification.

Further, in the above embodiment, the case where the television camera 2 and the monitor 10 each having the pan / tilt head 4 are one set has been described, but a plurality of television cameras 2 and a plurality of monitors 1 are provided.
0 is provided, the touch panel 11 is attached to one monitor 10, a basic image is displayed, and an enlarged / reduced image is displayed on another monitor 10, and other various combinations are possible.

Further, in the above embodiment, an example in which the touch input section 12 of the touch panel 11 is divided into 64 pieces is shown, but the X and Y axes of the screen are divided into tens, hundreds and thousands to make many touches. It is possible to set the input unit 12 and execute fine photographing operation control. Furthermore, touch input on the touch panel 11 may be performed by means other than a finger, such as a pen.
