Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a remote control pan head apparatus capable of horizontally and vertically turning a pan head mounted with a television camera and a lens mainly used in broadcasting stations and the like and remotely controlling the lens.
[0002]
[Prior art]
Conventionally, many broadcast stations have been installed indoors and outdoors as news studios or weather cameras, as described in Japanese Patent Application No. 63-77539 previously proposed by the applicant. A plurality of operation states of the camera platform and the lens are stored as shot data, and one of these shot data is selected by a reproduction switch at the time of reproduction, and is linearly moved from the current operation state to the state of the shot data. In this way, the trajectory data is created by calculation by the arithmetic circuit, the operation state of the camera platform and the lens is continuously stored for a certain period of time, and the stored trajectory data is continuously trace-reproduced in the order of the storage time by the playback switch. Such a method is performed.
[0003]
[Problems to be solved by the invention]
However, in the trace playback of the above-described conventional remote control pan head, playback is performed continuously in the order of storage time. For example, when traffic information is broadcast in a news program, the shooting state of a curved highway is recorded as trajectory data. If the data is stored in advance, the traffic congestion status changes with the passage of time during the broadcast time, or the traffic conditions in the up and down directions differ, so the input trajectory data cannot be used. Occur.
[0004]
Furthermore, since the broadcast time using this type of equipment in a news program changes with the progress of the program, even if the storage time of the trajectory data is determined in advance, the broadcast time in the actual broadcast It becomes unreasonable to try to execute it according to the time assumed in advance because it becomes shorter or longer.
[0005]
Further, when changing the trajectory data immediately before the broadcast time, it is impossible in time for one operator to operate several remote control pan heads. Requires skilled operation techniques, so not all operators can respond to changes in the input of trajectory data. Will occur.
[0006]
An object of the present invention is to solve the above-mentioned problems, select an arbitrary section on the trajectory data by operating the playback switch, reproduce the trajectory data, and match the broadcast time and a desired shooting state with a simple operation. It is to provide a remote control pan head device capable of performing the above.
[0007]

[0008]
According to a second aspect of the present invention, there is provided a remote control pan / tilt head device comprising a pan / tilt head on which a lens and a camera are mounted, and an operation member for remotely operating the lens and pan / tilt head, and operating the lens and pan head from the operation member. An arithmetic circuit that records the state as trajectory data in the storage unit for a certain period of time, a plurality of playback switches, and a playback switch setting means that associates each of the plurality of playback switches with an arbitrary position of the trajectory data. In response to the operation of the first regeneration switch among the plurality of regeneration switches that specify the start position of the section, the section moves from the current position to the position corresponding to the operated first regeneration switch, and the regeneration section The trajectory data of the playback section is recalled in the recording forward direction or in the reverse direction by operating a second playback switch of the plurality of playback switches that specify the end position of Playing Te, characterized in that to reproduce the operation state of the lens and the camera platform.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 shows a configuration diagram of the first embodiment. A storage unit 2 is provided in an arithmetic circuit 1 for controlling a remote control pan head device, and an output of the arithmetic circuit 1 is a pan head driving circuit 3 for driving the pan head. It is connected to a lens driving circuit 4 that drives the lens. The arithmetic circuit 1 also has outputs of an operation member 5 for manually operating the pan head and lens, a storage switch 6 for starting recording of locus data, and a plurality of reproduction switches 7a to 7j corresponding to predetermined storage positions. It is connected.
[0010]
Now, assuming that 10 playback switches 7a to 7j are provided, the storage time is 18 seconds, and the storage position is assigned to each of the playback switches 7a to 7j at intervals of 2 seconds. Then, the lens operating member 5 is operated to determine the position at which to save the trajectory data.
[0011]
Next, the storage switch 6 for trajectory data is pressed and the storage switch 6 is turned on to display the storage mode. From that time, the camera platform and lens operating member 5 are operated according to the composition of the imaging state for 18 seconds, and the state is continuously stored in the storage unit 2 as trajectory data. When the storage time ends, the storage state of the trajectory data automatically ends and the storage switch 6 is turned off.
[0012]
It is also possible to check the remaining recording time by displaying the reproduction switches 7a to 7j in order from the left in order to display the storage progress. At this time, the arithmetic circuit 1 outputs the operation state to the pan head control circuit 3 and the lens driving circuit 4, and stores the trajectory data while checking the video of the TV camera so that the same operation as the stored trajectory data is performed. It can be performed.
[0013]
FIG. 2 is a graph showing the relationship between the trajectory data of the horizontal turning and the reproduction switches 7a to 7j. Each of the reproduction switches 7a to 7j has a storage start position, an elapsed position every 2 seconds from the storage start, and a storage end position. Assigned sequentially.
[0014]
When the storage of the trajectory data is terminated, the reproduction mode is automatically selected, and all the reproduction switches 7a to 7j are turned off. When one playback switch, for example, the playback switch 7f is operated with all the playback switches 7a to 7j turned off, the playback switch 7f is turned on at a speed specified from the current operation state to the locus of the playback switch 7f. Move and this is the cueing operation.
[0015]
Next, when the playback switch 7i is operated to display the lighting of the playback switch 7i, the playback switch 7i moves on the locus shown in the figure in 6 seconds, and first the playback switch 7f and the playback switch 7g perform the flashing display while moving on the locus. That is, the two playback switches 7f and 7g close to the corresponding storage position sequentially perform flushing display in accordance with the movement, and when the movement is finished at the end, only the lighting display of the playback switch 7i remains, and the movement on the locus does not move. Shows that it has finished.
[0016]
If the playback switch 7c is pressed during the movement of the locus, it is considered that the destination is changed, the reproduction switch 7i is turned off and the reproduction switch 7c is turned on. Are reproduced along with the movement display in this case. Further, if the playback switch 7 that is performing the flushing display is operated during the movement of the locus, an operation for stopping the temporary movement can be performed at that position.
[0017]
When the trajectory movement is completed, when the playback switch 7 that is lit is operated, the playback switch 7 is turned off, and the head can be set and the pan head and the lens can be manually operated. In addition, if the camera platform and the lens operating member 5 are operated during the movement of the trajectory, the trajectory movement is automatically terminated, and the manual operation state and the cueing state can be achieved.
[0018]
Further, the storage state of the trajectory data can also be updated by performing the operation again as described above. To cancel the storage state of the trajectory data, the lit storage switch 6 is turned off again. It can be carried out. It is also possible to provide a plurality of such track data storage states.
[0019]
FIG. 3 is a block diagram of the second embodiment, and the same reference numerals as those in FIG. 1 represent the same members. 1, the arithmetic circuit 1 includes a reproduction switch setting member 8 for setting ten reproduction switches 7a to 7j, a time indicator 9, a storage time setting start switch, and a storage time setting volume. The output of the storage time setting member 10 is connected.
[0020]
First, before starting to store the trajectory data, the storage time setting start switch is operated to display the storage time on the time display 9. The display time is a value obtained by converting the state of the storage time setting volume into time, and when the storage time is changed by this display time, the volume is operated while viewing the display time. Further, when the storage time setting member 10 is composed of a time increase / decrease operation switch, a standard time determined in advance is displayed, and when the storage is changed according to this display time, the time is increased. This is done by operating the switch for time or the switch for time reduction. Thereafter, when the trajectory data storage switch 6 is pressed, the operation state operated by the pan / lens operating member 5 is stored in the storage unit 2 as trajectory data, and the remaining time is displayed on the time display 9. .
[0021]
The reproduction switch setting member 8 is constituted by a switch, and when this switch is pressed, the reproduction switch setting member 8 automatically moves to the storage start position, and the time indicator 9 at this time indicates 0 second. Thereafter, the entire trajectory data is automatically reproduced and the reproduction time is displayed on the time display 9. In this case, the reproduction switch 7 performs the flushing display one by one in order from 7a, and when the corresponding reproduction switch 7 is operated to complete the operation of setting the storage position of the trajectory data to each reproduction switch 7, The manual operation state and the cueing state are established. The same procedure can be used to change the storage position of the playback switch 7 that has already been set, and the subsequent playback operation is also performed as described above.
[0022]
FIG. 4 is a graph showing the relationship between the trajectory data of the horizontal turn and the reproduction switches 7a to 7j. The storage time is set to 22 seconds, and the storage positions of the respective reproduction switches 7 are allocated at unequal time intervals. . As shown in FIG. 4, the reproduction switches 7a to 7j do not necessarily have to assign storage positions with 1 second as a reference unit.
[0023]
【The invention's effect】
As described above, the remote control pan / tilt head device according to the first aspect of the present invention, once the lens and pan / tilt head data are input, can be operated by arbitrarily operating the playback switch to set any length of the trajectory data to any length. In addition, since playback can be performed regardless of the temporal order of storage, television program production can be quickly handled according to the situation of the subject to be photographed and the broadcast allocation time. Furthermore, since a large number of playback states are possible even with a single piece of trajectory data, an operation similar to having a lot of trajectory data can be performed.
[0024]
Further, the remote control pan head device according to the second invention can arbitrarily set the storage time of the trajectory data, and can select any location of the trajectory data for each reproduction switch, so that the trajectory data can be used more effectively. In addition, even an operator who is not skilled in remote control pan head operation can realize camera work different from the conventional one, and can be used effectively for TV program production.
