Hereinafter, the operation of this embodiment will be described with reference to FIG.

When the power of this embodiment is turned on, the internal circuit of this embodiment is initialized (step 72).

Next, it is determined whether or not the T switch 45 is on (step 73).

If this T switch is off, the TV camera 62
The pan head 61 is manually operated by operating the control box 63. That is, a voltage value corresponding to the operation amount of the focus knob 31, the zoom knob 32, and the operation stick 33 is output from each potentiometer 34, and is converted into a digital signal by the A / D converter 35, and then input to the control circuit 36,
In the control circuit 36, the D / A converter 46
The same signal is output to the D / A converter 46 (step 74), and is converted into an analog control signal by the D / A converter 46, and then becomes a servo signal by the servo amplifier 47. At this time, if the OFS switch 48 is in the OFF state, the output servo signal of the servo amplifier 47 is directly input to the various mechanisms 50 and the television camera 62 or the pan head 61
Are manually operated. In addition, OF
When the S switch 48 is in the ON state, the offset amount set by the offset circuit 49, that is, the offset amount corresponding to the offset amount set by each of the offset switches 66, 67, 68, 69 is the servo amplifier 47 The sum is added to the output servo signal and applied to each mechanism 50. In other words, in this case, the offset knob
The offset amounts set in 66, 67, 68, and 69 are added, and the manual operation is performed.

Next, when the T switch 45 is in the ON state, that is, when the television camera 62 or the camera platform 61 is operated in the trace mode, first, it is determined whether or not shot selection has been performed, that is,
It is determined whether or not any one of the ST switches 44 is on (step 75). And which of
If the ST switch is not in the ON state, the address on the RAM 40 corresponding to the shot selected at the end of the previous operation is selected (step 76). That is, in this case, the last shot of the previous operation is traced.

If any of the ST switches 44a, 44b,..., 44j is in the ON state, an address in the RAM 40 corresponding to the shot corresponding to the ST switch in the ON state is selected (step 77).

Next, it is determined whether or not the WR switch 42 is on (step 78). That is, it is determined whether the write mode is in the standby mode.

If the WR switch 42 is on and the write mode is standby, the state of the S / S switch 41 is determined (step 79). That is, it is in the write standby state, and waits for the start switch to be pressed. If the S / S switch 41 is not turned on, the state of the ST switch 44 is determined again, and it is determined whether any shot is selected.

When the S / S switch 41 is pressed from this standby state and an operation start command is issued, a recording start signal of the VTR 65 is output (step 80), and the operation amount of the operation means detected by the potentiometer 34 is changed to A / A. The signal is converted into a digital signal by the D converter 35 and output to the D / A converter 46 via the I / O port 37 (step 81). At the same time, the manipulated variable is input to the CPU 39, and the R corresponding to the selected shot is
The operation amount data is sequentially written at a predetermined address on the AM 40 (step 82). The signal output to the D / A converter 46 is converted into an analog signal by the D / A converter 46 and then input to the servo amplifier 47,
Is converted into a servo signal and output to each mechanism 50, and the F, Z, P, T operations of the television camera 62 or the pan head 61 are controlled.

In the present embodiment, the recording start signal is output to the VTR 65 at the same time that the S / S switch 41 is turned on. However, the VTR 65 is not used inside the television camera 62 or the control box 63 or the cloud. Video RAM in part of the platform 61
May be provided to store the video signal. Further, the VTR 65 may not be connected to the control circuit 36, and the operator may manually start recording.

The optimal F, Z, P, T values for photographing the person 98 going up and down the stage 97 as described above are stored in the RAM 40, and at the same time, the video signal of the person 98 is recorded on the VTR 65. It will be.

In this way, while the imaging operation is being performed while operating the camera platform 61 and the television camera 62, the S / S switch 41 is operated.
Is pressed again to turn it off (step 83), the storage area of the address of the selected shot on the RAM is terminated (step 84), or the ST switch 44 corresponding to another shot is on. If not (step 85), the recording operation ends, and the control circuit 36 outputs a recording end signal to the VTR 65 (step 87).

If the ST switch 44 corresponding to another shot is turned on (step 85), the selected shot is terminated as soon as the storage area of the address on the RAM 40 corresponding to the previous shot ends (step 84). The address on the RAM 40 is selected (step 86), and the F, Z, P, and T values are subsequently stored in the storage area of the address.

Thus, the video signal serving as the basis for shooting in the trace mode and the data necessary for various imaging operations are stored.

Then a TV camera based on this stored data
A photographing operation in a trace mode in which photographing is performed while driving the camera platform 62 or the camera platform 61 will be described.

In this case, since the operation is in the trace mode,
The T switch 45 is on (step 73), and the address of the shot selected by the ST switch 44 on the RAM 40 is selected (steps 75, 76, 77).

Next, in this case, since the reading mode is set, the WR switch 42 is turned off (step 78), and the RD switch 43
Is turned on (step 88).

Step 75 while the RD switch 43 is not pressed yet
And the state of the ST switch 44 is determined again.

When the RD switch 43 is pressed, a read standby state is set, and the state of the S / S switch 41 is determined (step 89).

As long as the S / S switch 41 is not pressed, the standby state is maintained, and the process returns to step 75 again to determine the state of the ST switch 44.

When the S / S switch 41 is pressed, the recording start signal of the VTR 65 is output (step 90), and the reading operation is started, and the data of the shot selected by the ST switch 44 is stored in the RAM 40. Is selected, and data is sequentially read from the head data of the address (step 91).

The data read from this RAM 40 is a D / A converter
The signal is output to the I / O port 37 via the I / O port 37 (step 92), converted into an analog signal by the D / A converter 46, output to the servo amplifier 47, processed into a servo signal, and output to each mechanism 50. .

Thus, the TV camera 62 or the pan head 61 reproduces its F, Z, P, T operations according to the drive data stored in advance, but when each operation means on the control box 63 is operated at the same time, The amount of operation is potentiometer 34, A / D
Input to CPU 39 via converter 35 and I / O port 37, C
I is added to the data called from RAM40 on PU39 and I
The voltage is applied to the mechanism 50 via the / O port 37, the D / A converter 46, and the servo amplifier 47, and the fine adjustment operation is manually performed in addition to the data stored in the RAM 40.

Thus, the data of the shot selected in the RAM 40 is sequentially read out, and each operation of F, Z, P, and T is controlled by the data on the RAM 40 or the data obtained by adding the operation amount of the operation means to the shot. During this process, the S / S switch 41 is pressed and turned off (step 93), or the RAM 4 of the selected shot is
Whether the storage area of the address on 0 ends (Step 9
4) If the ST switch 44 corresponding to another shot is not turned on (step 95), the TV camera
The control operation of 62 or the pan head 61 ends, and at the same time, a recording end signal is output to the VTR 65. (Step 87).

In this case, as in the above-described write mode, if the ST switch 44 corresponding to another shot is turned on (step 95), the storage area of the address on the RAM 40 corresponding to the shot being read out. Is completed (step 94), the address of the selected shot on the RAM 40 is selected (step 96), and the data written to the address is read.

The above is the operation of the trace mode disclosed in the first invention of the present applicant.

As shown in FIG. 13, while reproducing in such a trace mode, in order to photograph the panel 99 and create the above-described composite image, the OFS switch 48 is turned on and the operation amount of the offset circuit 49 is servo-controlled. What is necessary is just to add to the output signal of the amplifier 47. That is, for example, each offset knob 66, 67,
The slider of the variable resistor 57 of the circuit shown in FIG.
, The offset amount Va as shown in FIG. 7 is added to the output signal of the servo amplifier 47.
The focus mechanism 50a, the zoom mechanism 50b, the tilt mechanism 50c, the pan mechanism 50d, and the like operate in a state where the offset amounts set by the respective offset knobs 66, 67, 68, and 69 are added, and the television camera 62 or the pan head 61 Is driven.

FIG. 4 is a block diagram showing a circuit configuration of the first embodiment of the television camera operating device of the present invention. In the embodiment shown in this drawing, the same components as those in the circuit configuration of the second embodiment shown in FIG. 5 are denoted by the same reference numerals, and their description is omitted.

In FIG. 4, the MEMO switch 70 is a switch for storing the offset amount. When the MEMO switch 70 is pressed while the OFS switch 48 is pressed, the operation amount of the operating means at that time is I. The data is stored at a predetermined address in the RAM 40 via the / O port 37.

Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS.

FIG. 15 provides a step (step 100) for determining the state of the OFS switch 48. When the OFS switch 48 is on, a subroutine step of the offset operation (step 10)
Except for the shift to 1), it is the same as the flowchart in the trace mode in FIG. That is, in the present embodiment, when the T switch 45 is in the off state, the value of the A / D converter 35 is immediately transmitted to the D / A converter 46 via the I / O port 37.
And the television camera 62 or the pan head 61 is driven, so that a manual control operation is performed (steps 73 and 74).

Next, when the T switch 45 is on, the OFS switch 4
The state of 8 is determined (step 100). And this OF
When the S switch 48 is off, that is, when the offset operation is not set, the operation in the trace mode shown in FIG. 12 is performed. The description of the steps is omitted.

In the present embodiment, when an offset is to be set for photographing a composite image shown in FIGS. 13 and 14, the T switch 45 is not turned on (step 73), and at the same time, the OFS switch 48 is turned off. When it is turned on (Step 1
00), and in this case, the process proceeds to the subroutine 101 of the offset operation.

The operation of the offset operation subroutine 101 is shown in the flowchart of FIG. That is, when the T switch 45 is on (step 73 in FIG. 15) and the OFS switch 48 is on (step 100), first, whether or not the offset MEMO switch 70 is in the pressed MEMO mode is determined. Is determined (step 102).

If in the MEMO mode, it is further determined whether or not the ST switch 44 has been pressed (step 103). If it is depressed, the process moves to the next step 104, where the address head data of the selected shot on the RAM 40 is read and output to the D / A converter 46 (step 104).

Next, it is set by the operation means, and the potentiometer 34, each A / D
The manipulated variable input via the converter 35 is immediately output to the D / A converter 46 via the I / O port 37 (step 105).

Next, when the leading data of the above-mentioned address of the selected shot on the RAM 40 is subtracted from the current value of the operation amount of the operation means fetched in step 105, the calculation result indicates the offset amount (step 106). That is, the operator operates the operation means to operate the F, Z, P, T of the TV camera 62 or the pan head 61.
Is set to an optimal state for photographing the panel 99, and subtracting the head data position of the scene in which the person 98 stored in the RAM 40 goes up and down the stairs 97 from now on,
That is, the offset amount is set.

In this state, it is next determined whether or not the MEMO switch 70 has been pressed (step 107).

If the MEMO switch 70 is still off, the process returns to step 105 again.

When the operator attempts to store the offset amount, the MEMO switch 70 is pressed.

If the MEMO switch 70 is turned on, go to step 10
The offset amount obtained in step 6 is stored in the storage area of the address corresponding to the offset amount in the RAM 40 (step 10).
8). At the same time, the offset MEMO mode is cleared (step 109). Then, the process returns to step 102 again.

In this case, since the MEMO mode has been cleared, the TV camera 62 with the offset amount added is added.
Alternatively, it is determined whether or not the data of the platform 61 is to be read. That is, the state of the RD switch 43 is determined (step 11).
0). If the RD switch 43 is off, the operator does not yet have the intention to perform the offset operation, so step 10
It returns to 2 and it stands by in this state.

When the RD switch 43 is operated to enter the readout mode (step 110), the state of the S / S switch 41 is determined next (step 111), and the operator waits for the state to start shooting in the offset mode. It will be. That is, since this state is also the standby state, the RD switch 43 described above is used.
In addition to the determination step (step 110), the standby state is doubled.

When the S / S switch 41 is pressed and turned on, a recording start signal is output to the VTR 65 (step 112).

Next, the state of the ST switch 44 is determined again (step 113). When the ST switch 44 is off, the RAM 4 corresponding to the shot when the power was turned off at the end of the previous operation.
The address data on 0 is read by the CPU 39 (step 11
4) If the ST switch 44 has already been operated and a specific shot has been selected, the RA corresponding to the selected shot
The data at the address on M40 is read by the CPU 39 (step 115). This is an unnecessary step when the TV camera 62 or the pan head 61 is operated after setting the offset amount.However, once the offset amount is set, the power is temporarily turned off, and after a while, the power is turned on. This is a step in consideration of the fact that shooting may be performed in the offset mode.

Next, the written offset amount is read from the address on the RAM 40 storing the offset amount corresponding to the selected shot (step 116).

And it was read in step 114 or step 115
The offset read out in step 116 is added to or subtracted from the data at the address on the RAM 40 (step 117).

Next, the calculation result is output to the D / A converter 46 (step 118), and the F, Z, P, T of the TV camera 62 or the camera platform 61 is output.
The operation is controlled with the offset amount added.

Of course, also in this case, the operation amount of the operation unit is input to the CPU 39 via the A / D converter 35, and the operation amount of the operation unit is further added to the data obtained by adding the offset amount to the trace mode data on the RAM 40. It goes without saying that fine adjustments can be made.

In this way, the panel with the offset amount added
The photographing operation of 99 is completed and the S / S switch 41 is turned off (step 119), the storage area of the address of the selected shot on the RAM 40 is terminated (step 120), or another shot is performed. If the corresponding ST switch 44 is not turned on (step 121), a recording end signal is output to the VTR 65 (step 122), and the shooting with a series of offset operations is completed. If the ST switch 44 corresponding to another shot is turned on (step 121), an offset amount is added and the storage area of the address in the RAM 40 corresponding to the shot being read is completed ( In step 120), the data written to the address of the selected shot on the RAM 40 is read out (step 115), and an offset amount is added to the data (steps 116 and 117), and the data of F, Z, P, T Each operation is controlled (step 118).

As described above, this embodiment corresponds to an embodiment of the invention described in claim 1 or claim 3.
Without providing the offset setting knobs 66, 67, 68, 69, by operating the focus knob 31, the zoom knob 32, or the operation stick 33, for example, the panel shown in FIG. 13 or FIG.
Television camera 62 or pan head in optimal condition for shooting 99
If 61 is set, the operation amount of the operation means is set as the offset amount (by the pressing operation of the MEMO switch 70),
The offset amount once set in this manner is stored in the storage area of the offset amount address of the RAM 40,
It is also possible to repeat the composite shooting as shown in FIGS. 13 and 14 many times, or to set the offset amount once and after the time has elapsed, to make a composite shooting or shoot the same place It is.

In the first and second embodiments, the control operation of the television camera or the camera platform of the television camera has been described only for focusing, zooming, tilting, and panning. It goes without saying that the present invention may be applied to a vertical movement operation or a parallel movement operation of the table.

In the above description of the embodiment, the TV camera 62
A case has been described in which a composite image is created by using one camera head and one camera platform 61, respectively.
As shown in the figure, two television cameras 62, 62 'and a pan head 6
It goes without saying that the present invention can also be applied to a case where a composite image is created using 1,61 '. These two TV cameras
When the heads 62, 62 'and the heads 61, 61' are used, a signal of the operation amount from the operation amount storage means 12 is output to the driving means 14 to the TV camera and the head on which the offset amount is not added. ,
The other TV camera and the camera platform may be driven so that a signal of the operation amount to which the offset amount is added is output to the driving unit 14.

〔The invention's effect〕

As described above, in the present invention, since the offset amount setting means for setting the offset amount is provided to drive the television camera or the camera platform on which the television camera is mounted, a plurality of images are separately captured. In the case of creating a composite image, control information of a television camera or a camera platform at the time of shooting of a video to be shot first is stored, and an offset amount of an image to be shot next is added to the storage data while adding an offset amount of the image to be shot. By driving and photographing the camera or the camera platform in the trace mode, it is possible to obtain an easy and accurate composite image.

Also, when two television cameras and a camera platform are driven in the trace mode, by driving the television camera and the camera platform on one side by adding an offset amount,
The same operation can be performed regardless of the difference between the initial positions of the two television cameras and the camera platform, and a composite image can be created extremely easily and accurately.

Furthermore, even when the same scene is photographed by the same operation in different seasons, the television camera and the camera platform can be operated exactly the same every time only by setting the offset amount, which is extremely accurate and easy. You can get a picture of changing seasons in the same place.
