Field of the Invention The present invention relates to a stage for realizing a predetermined effect by using a lighting device or another effect device in, for example, a theater, a studio, a hall, or another stage where an actor performs. It is related to the production method.

[0002]

2. Description of the Related Art In general, various effect devices are used in order to achieve a desired effect with the performance of an actor on a stage such as a theater. At present, as a directing device, for example, a lighting device such as a spotlight for locally illuminating a specific place on a stage, an audio device for generating music, sound effects, and other sounds, and a light source for the background of the stage. A video device that displays an image according to an image, a stage provided on the stage that exerts a specific effect when actuated, for example, a cell, a smoke screen device, or other movable device that raises or lowers an actor or prop from the abyss on the stage 2. Description of the Related Art A type effect device is known.

[0003] Stage performances usually need to be performed in response to individual actions or movements in human performance or performance, but it is understood that such performers' movements are strictly controlled. Is irregular and never follows a certain pattern in time and place. Therefore, in the production on the stage, usually, one producer observes the movement and situation of the performer on the stage according to a predetermined program, and gives a specific cue sign, for example, voice or gesture according to the progress of the performer's performance At present, the cue sign is used as a trigger for the operator of various effect devices to operate the effect device in charge in accordance with a predetermined program in the scene, and is currently being executed.

[0004] However, in such a stage production performing method, it is necessary for the producer to present an extremely large number of complicated cue signals for each scene, which is a great burden. In addition to the need for specialized operators, each operator is required to have high operation skills, and there are problems such as individual differences in operator skills and operator fatigue. It is very difficult to execute repeatedly by sex.

[0005] From the above viewpoints, a technique for driving the operation of each of various production devices in a controlled state according to a predetermined program in a desired manner has been developed, and some of them have been put into practical use. It has become. For example, in a lighting device, a device that controls the lighting direction and the lighting state to change in a manner according to a specific program is known. Among them, the lighting effect by the lighting device is a very important thing that is indispensable in the stage effect, and should be executed in a very various manner.

Further, a control device is provided for each of the effect devices for controlling the plurality of effect devices, and signal control means for supplying a control signal to each of the control devices is provided. A device for automatically controlling each of the effect devices using a state signal indicating another state as a cue signal has been proposed, for example, in Japanese Patent Application Laid-Open No. 4-43409.

As a result, there is a problem that it is not possible to accurately drive and control the effect device to reliably achieve the desired effect.

As a device automatically controlled in accordance with the movement of a person or the like on the stage, for example, an automatic spotlight tracking device has been proposed in Japanese Patent Laid-Open Publication No. Sho 64-33802. As the moving object moves,
The light projection direction of the lighting device is controlled to automatically track the moving object. However, in this device,
The control of the lighting direction of the lighting device is performed only in a simple form of tracking the moving object, and a lighting effect completely different from the effect produced by other effect programs is performed. Effects cannot be obtained.

[0010] An object of the present invention is to use a position information as a basic cue signal in accordance with the movement of a moving object that moves irregularly on the stage, that is, a predetermined position based on the position of the moving object. Various stage production devices operated according to the stage production program can be automatically driven, so that the intended stage production effect can be reliably achieved with sufficient flexibility and sufficiently high reproducibility. It is to provide a method.

[0011]

And performing the start procedure.

[0013]

[0014]

It is preferable to provide a pin or a clip for fixing 0 to a part of the costume of the performer.

More specifically, three or more or four or more ultrasonic detectors 40 are arranged at appropriate intervals. The specific arrangement state of the ultrasonic detection device 40 is the theater 1
In addition, they are appropriately set in accordance with the size, structure, and other conditions of the stage 2, and are installed in the theater 1 at, for example, a ceiling, a wall, a floor, and other appropriate fixed positions in a state where they are separated from each other. For example, as shown in FIG. 3, the four ultrasonic detectors 40 are arranged at three-dimensionally different positions so that all of them are not present on the same plane. Preferably.

Each of the ultrasonic detectors 40 has a time counter 41 and an ultrasonic detector 42. The time counter 41 starts a time measuring operation in response to a start command signal from the central controller 10, and The ultrasonic detector 42 stops the time measurement operation by detecting the ultrasonic wave, and thereby measures the ultrasonic arrival time T from the time when the central control device 10 transmits the start command signal to the time when the ultrasonic wave is detected.

In order to exhibit such a function, the arithmetic unit 12 stores, for example, coordinates occupied by each of the ultrasonic detection devices 40 in a three-dimensional spatial coordinate system arbitrarily set with an arbitrary position in the theater 1 as an origin. Position data based on the position is registered, and the position data can be called up as needed.

The lighting device 50 as a directing device includes a stage 2
It is installed at a fixed position facing the. This lighting device 50

Further, the lighting device 50 includes a lighting state control mechanism (not shown) for controlling the lighting state of the light source lamp 51.

The lighting direction control mechanism and the lighting state control mechanism of the lighting device 50 are connected by wire or wireless so that data communication is possible with the effect device control unit 13 of the central control device 10. Is registered so that the position data based on the coordinate position occupied in the spatial coordinate system can be called. The lighting direction control mechanism and the lighting state control mechanism are each independently started to be driven by a drive start signal from the effect device control unit 13 and are operated in accordance with a lighting program predetermined in the effect device control unit 13. You. That is, the rendering device control unit 1

Specifically, based on two vectors connecting each of these two spatial coordinates and the spatial coordinates of the lighting device 50, the ultrasonic transmitting device 30 and the lighting device 50 held by the moving moving body are Is obtained.
The illumination direction of the illumination device 50 is controlled based on this vector.

The acoustic device 60 includes, for example, a recording tape,
The central control unit 10 includes a device for reproducing sound recorded from a recording medium such as a disk, a sound effect generating device, and the like.
Is connected by wire or wireless in a state where data communication is possible to the effect device control unit 13, and the drive is started by an audio device drive start signal from the effect device control unit 13, and is determined in advance by the effect device control unit 13. It is operated according to a sound program.

In the theater 1 having the above-described facilities, according to the stage effect performing method of the present invention, a moving body coordinate information obtaining procedure for obtaining coordinate information indicating a position of the moving body, a moving body coordinate confirmation procedure, An effect device drive start procedure is executed.

<Moving Object Coordinate Information Acquisition Procedure> The moving object coordinate information obtaining procedure is a procedure for obtaining coordinate information on the position of the moving object in a spatial coordinate system set on the stage. It is.

The central control device 10 sends a transmission command signal to the radio wave transmitting device 20, and at the same time,
, A start command signal of the time counter 41 is sent. Thus, the radio wave signal R transmitted from the radio wave transmitting device 20
Is detected by the radio wave detector 31 of the ultrasonic transmission device 30, and at the same time, the ultrasonic wave S is transmitted from the ultrasonic transmission device 30.

On the other hand, in the ultrasonic detector 40, the time counter 41 is initialized by the start command signal, and the measuring operation is started. Then, after that, the ultrasonic detector 42 detects the ultrasonic wave,
The measurement operation of the time counter 41 is stopped. Time data based on the measurement time is transmitted from the time counter 41 to the time measurement system control unit 11 of the central control device 10,
It is supplied to the calculation unit 12.

Here, the time T measured by the time counter 41 is the time from when the start command signal is transmitted to when the ultrasonic wave is detected by the ultrasonic detector 40. Since the time from the transmission of the ultrasonic wave by the ultrasonic transmission device 30 to the transmission of the ultrasonic wave is extremely short, it can be practically ignored. Therefore, the measurement time T is calculated from the time when the ultrasonic transmission device 30 transmits the ultrasonic wave to the ultrasonic detection device. This is substantially the same as the time until the detection of the ultrasonic wave by 40. Therefore, the time data corresponds to the distance d (see FIG. 2) between the ultrasonic detecting device 40 and the moving body holding the ultrasonic transmitting device 30.

The arithmetic unit 12 of the central control unit 10 calculates, for example, three or four time data selected from the time data transmitted from each of the ultrasonic detecting devices 40,
Based on the position data of the ultrasonic detection device 40 relating to the time data, the coordinate position of the ultrasonic transmission device 30 in the spatial coordinate system is calculated from the magnitude of the velocity of the ultrasonic wave.

When a large number of ultrasonic detecting devices are provided,
In this case, the time data to be selected are sequentially selected from those having the smallest detection time T related to the time data by all the ultrasonic detection devices 40 or those having the largest ultrasonic energy detected by the ultrasonic detection device 40. Preferably, they are selected in order. Such time data in which the detection time T is short or time data in which the energy of the detected ultrasonic wave is large is actually obtained by the ultrasonic detection device 40 located in the region closest to the moving body. Therefore, by selecting the time data in this way, it is possible to reliably avoid detection of noise ultrasonic waves that cause an error such as ultrasonic waves reflected by a theater wall or the like.

When three time data are used, the coordinate position of the ultrasonic wave transmitting device 30 can be calculated according to the following principle. That is, as shown in FIG. 6, the ultrasonic detecting device 40 and the ultrasonic transmitting device 3 are calculated based on time data detected by the three ultrasonic detecting devices 40.
When the distances between 0 are r1, r2, and r3, and the positions of the ultrasonic detection devices 40 are P1, P2, and P3, the positions of the ultrasonic transmission devices 30 are points P1, P2, and P, respectively.
It should be on the intersection of three spheres S1, S2, S3 centered at 3 and with radii r1, r2, r3. More specifically, a set of intersections of the two spherical surfaces S1 and S2 is a circle, which is shown as a hatched ellipse H in FIG. The intersection of the ellipse and the spherical surface S3 is the intersection of the three spherical surfaces. Therefore, simultaneous equations representing such three spherical surfaces S1, S2, and S3 in the space coordinate system may be set and solved to find the solution. Here, the number of obtained solutions is 1 or 2, but 2
When there are two solutions, a more rational solution is selected in consideration of other conditions, for example, the level in the height direction of the moving object.

In the case of four time data,
As shown in FIG. 7, the coordinate positions of the four ultrasonic detection devices 40 in the X, Y, Z space coordinate system are (x ₁ , y ₁ ,
z ₁ ), (x ₂ , y ₂ , z ₂ ), (x ₃ , y ₃ ,
z ₃ ), (x ₄ , y ₄ , z ₄ ), and the ultrasonic transmitter 3
When the coordinate position of 0 is (x, y, z), the distance d between the ultrasonic transmitting device 30 and each of the four ultrasonic detecting devices 40 is d.
Each of 1, d2, d3 and d4 is represented by the following formulas. (D1) ² = (xx ₁ ) ² + (yy ₁ ) ² + (zz ₁ ) ² (d 2) ² = (xx ₂ ) ² + (yy ₂ ) ² + ( ^{_{z-z 2) 2 (d3}} ) 2 = (x-x 3) 2 + (y-y 3) 2 + (z-z 3) 2 (d4) 2 = (x-x 4) 2 + (y- y ₄ ) ² + (z−z ₄ ) ² Therefore, by solving the above equations for x, y, and z, the coordinate position (x,
y, z) can be calculated exactly.

In the above, the time counter 41 in the ultrasonic detection device 40 can measure time with an accuracy of, for example, about 0.0001 seconds. Therefore, although this accuracy is related to the range of the error in the position data of the ultrasonic transmitting device 30, the air propagation speed of the ultrasonic wave is about 340 m.
/ Sec, the error in the distance on the stage is at most 3.4 cm, so that it is possible to obtain the coordinate position of the ultrasonic wave transmitting device 30, that is, the moving body with extremely high accuracy.

In the above, the time density of the transmission of the transmission command signal by the central control device 10 is, for example, 2 per second.
0 times, and the time interval is 50 msec.
The time that can be measured by the time counter 41 of each ultrasonic detection device 40 needs to be less than about 50 msec at the longest. Then, since the range of the distance that the ultrasonic wave reaches within the longest measurement time in the time counter 41 is the detectable area covered by the ultrasonic detection device 40, the longest measurement time of the time counter 41 is set to 45 msec. In such a case, since the air propagates in the air at a velocity of about 340 m / sec, the detectable region of the ultrasonic detection device 40 is a spherical region having a radius of 15.3 m. Therefore, the ultrasonic detecting device is an ultrasonic transmitting device.
14. Radius centered on the position of the object, that is, the position of the object
It suffices that three or more pieces exist in a 3 m spherical area.

The length of time required for one moving object coordinate information acquisition operation, that is, the time required from the transmission of the transmission command signal by the central control device 10 to the control of the lighting device is determined by the ultrasonic transmission device. 30 and ultrasonic detection device 4
Although it depends on the magnitude of the distance from 0, for example, 50 to 2
It is about 00 msec. This is because the transmission of the transmission command signal by the central control device 10, in other words, the transmission of the radio signal is performed at a time interval of about 5 to 20 times per second, that is, 200 m.
This means that the operation can be performed at a short time interval of less than or equal to sec. Therefore, it is practically possible to always acquire the coordinate information of the moving object A.

<Movement Coordinate Confirmation Procedure> This procedure is performed in the arithmetic unit 12 of the central control unit 10. Specifically, a specific area is set on the stage 2, and when coordinate information belonging to a range of coordinates corresponding to the specific area is obtained by the arithmetic unit 12, the movement is performed by the arithmetic unit 12. This is executed by supplying the body coordinate confirmation signal to the effect device control unit 13. This moving object coordinate confirmation signal is
This means that the moving body A has moved to reach the specific area, thereby achieving a state where the moving body coordinate information satisfies the setting conditions for the specific area.

<Procedure Device Driving Start Procedure> The above-described moving object coordinate confirmation procedure is executed and a moving object coordinate confirmation signal is supplied to the rendering device control unit 13. A drive start signal is supplied to the rendered effect device, and the drive of the selected effect device is started by the drive start signal, and the effect device is operated according to a predetermined effect program.

The operation continuation time of the rendering device in the rendering device drive start procedure described above can be freely set according to the content of the rendering, but is set in units of one scene of the rendering performed in a normal case. Is preferred. Here, the time of one scene is 10 to 2 in the case of a normal scene.
0 seconds. However, it goes without saying that the effect device can be continuously operated during a plurality of continuous scenes. The term “continuously operated” means that it is operated by one drive start signal, and includes a time during which the effect device is in effect suspended during the continuous operation time. May be.

For example, if the selected rendering device is the lighting device 5
When the value is 0, the driving of the lighting direction control mechanism and the lighting state control mechanism is started by a driving start signal from the rendering device control unit 13, and thereafter the lighting direction control mechanism and the lighting state control mechanism are operated according to a predetermined lighting program. Then, when the driving start signal is supplied, since it is confirmed that the moving body A has reached a specific area, using the coordinate information acquired by the moving body coordinate information acquisition procedure, Lighting device 50
The illumination direction control mechanism can be controlled such that the illumination direction of the moving object A is changed using the moving object A as a reference.

Further, based on the coordinate information of the moving body obtained by the moving body coordinate information obtaining procedure, the coordinate information of the position of the lighting device 50, and the driving characteristic value of the driving mechanism 56, the central control device 10 The illumination direction control mechanism can be controlled by a control signal from the illumination control unit 13 so that illumination in the target illumination direction based on the position of the moving object is achieved.

The mode of illumination by the illumination device 50 can be set in an illumination program, and more specifically, the illumination can be set in various modes using the moving object as a position reference. The simplest mode of illumination is to directly illuminate the position of the moving object A. In this case, the direction of the coordinate position of the moving object A is the target illumination direction. Further, a location having a specific positional relationship with respect to the moving body A, for example, a position separated from the moving body A by a specific distance in a specific direction can be set as the target illumination direction. The light spot moves with the movement of the body A.

Further, it is also possible to adopt a mode in which the specific positional relationship changes over time, for example, a mode in which the light spot moves along an arc centered on the moving body A. Also in this case, when the moving body A moves, the moving center of the light spot moves accordingly. The mode of the change of the position of the light spot can be executed in any mode such as a mode in which the light spot is switched at a time, a mode in which the illumination position is gradually moved, and a mode in which the position is gradually moved. When a plurality of lighting devices are used, by controlling each of them as described above, it is possible to execute lighting in a more complicated manner.

Further, by controlling the lighting state control mechanism for the lighting device 50, it is possible to easily achieve various effect effects. For example, as described above, the illumination direction control mechanism is controlled so that the position of the moving body A is always in the target illumination direction, and the light source lamp is switched from the unlit state to the lit state, thereby setting the stage 2 in the dark. At the moment when the moving body A that has moved above reaches a specific area, it is possible to execute illumination for surely projecting a spotlight on the moving body A. Illumination in this manner cannot be performed with sufficient reliability in conventional devices.

The selected effect device is an audio device 60.
In the case of, the driving of the acoustic device 60 is started,
A sound is emitted on the stage 2 for a certain time according to the determined production program. Furthermore, when another type of effect device is selected, a special effect effect by the effect device is realized.

The processing of the main information for each procedure described above is executed by the arithmetic unit 12 and the rendering device control unit 13 of the central control unit 10. Then, the cue signal is used to start driving each of the effect devices. Here, there are various types of information that can be used as the cue signal, such as coordinate information of the moving object, acoustic information, lighting information, and information on the effect of the effect by other effect devices, and can be distinguished from others. Any specific information can be used.

FIGS. 8 to 10 are charts showing specific examples of information processing procedures when performing a stage effect for realizing a certain effect by a series of procedures as described above. In these figures, steps surrounded by a rectangular frame represent information processing, and steps surrounded by a diamond-shaped frame represent determination processing. In the determination process, a downward arrow indicates an output of “YES” and a horizontal arrow indicates an output of “NO”, and a direction to a processing step to be executed is indicated by a thick arrow.

The effect set in this example is that when the singer moves to and reaches a central specific area on the darkened stage, the drive of the sound device is started and the singer's song to be sung is started. The sound effect that starts the reproduction of the accompaniment music starts, and thereafter, when the prelude portion of the music ends, the lighting device executes a lighting effect in such a manner that a spotlight is suddenly formed at the position of the singer by the lighting device. What you want to do. Therefore, in this production example,
The singer's coordinate information is used as a basic cue signal to start driving the sound device, and the lighting direction control mechanism of the lighting device controls the position of the singer as the target lighting direction, and furthermore, as a weighted condition, a prelude to music May be used as a cue signal using the specific acoustic information at the end of the process to control the lighting state control mechanism of the lighting device.

The effect of this example is executed by, for example, the following processing steps S1 to S13. Step S1 This is a step of determining which type of information is used as the cue signal of the effect. In this effect example, the singer's coordinate information and acoustic information may be considered. Step S2 is a step in which it is determined whether or not the coordinate information is used as a cue signal. Step S3 This step is to execute a coordinate information acquisition procedure when it is determined in step S2 that "use coordinate information". Step S4 This is a step in which it is determined whether or not the coordinate information acquired in step S3 has realized a state that satisfies a preset condition relating to a specific area.

Step S5 If it is determined in step S4 that a state satisfying the set conditions has been realized,
Specifically, it is a step of selecting which effect device is to execute the effect by what effect device. Here, the program to be selected is one in which the rendering device and each aspect are predetermined, and can be designated by, for example, a number attached thereto,
In particular, a specific condition may be set for a cue signal at which driving of the program is to be started.

Examples of the program include the following. The sound program 1 is selected as the sound effect, and the lighting program 2 is selected as the lighting effect. The sound program 1 is selected as the sound effect, and the lighting program 2 is selected under the condition that the specific sound information in the sound program 1 is used as the cue signal. Selection The lighting program 3 is selected as the lighting effect, and the sound program 2 is selected under the condition that the specific lighting information in the lighting program 3 is used as the cue signal for the sound effect.

Step S6 This is a step in which it is determined whether or not the acoustic information is used as a cue signal (a cue signal for an illumination effect in this example of the effect). Step S7 This is a step of acquiring acoustic information when it is determined in step S6 that "use acoustic information". Step S8 This is a step in which it is determined whether or not the acoustic information acquired in step S7 has achieved a state satisfying a preset specific condition.

Step S9 If it is determined in step S8 that a state satisfying the set conditions has been realized,
This is a step of specifically selecting a program effect effect to be executed. Here, the selected program is the same as that in step S5. Examples of programs include the following. Select lighting program 2 for specific sound information as cue signal and lighting effect Select new sound program 4 for specific sound information as cue signal Select coordinate information with specific sound information as cue signal

Step S10 This is a step in which it is determined whether the sound effect selected in step S5 or step S9 may be executed, specifically, whether or not the supply of the sound device driving start signal is permitted. Step S11 This is a step of supplying an audio device drive start signal to the audio device based on the determination in Step S10. Step S12 This is a step in which it is determined whether the lighting effect selected in step S5 or step S9 may be executed, specifically, whether or not the supply of the lighting device drive start signal is permitted. Step S13 This is a step of supplying a lighting device drive start signal to the lighting device based on the determination in Step S12.

First Information Processing Cycle The first information processing cycle shown in FIG. 8 is a process for starting a sound effect using singer's coordinate information as a cue signal. This first information processing cycle includes step S1
Step S13, and the contents of the processing in each step are as follows.

In step S1, the use of the coordinate information among the singer's coordinate information and the sound information used as the cue signal is determined, and the non-use of the sound information is determined. The processing of step S2 and step S6 is controlled according to the content of this determination. In step S2, since the use of the coordinate information is affirmed, the determination result is “YES”. In step S3, a command to acquire the singer's coordinate information is issued,
The coordinate information is obtained using the ultrasonic wave as described above.

In step S4, it is determined whether or not the singer has moved and reached the set area of the stage. If the determination result is "NO", the subsequent steps are omitted, and the operation of returning to step S1 is continued until the determination result becomes "YES". In step S5, step S4
Is "YES", a program is selected. In step S6, it is determined whether or not the selected program uses the audio information as the cue signal. However, since the audio information is not used in the first information processing cycle of this production example, the determination result is “NO”. Becomes

Steps S7 to S9 are omitted based on the result of the determination in step S6, and the process proceeds to step S10. In step S10, the determination result is "YES" based on the results of step S4 and step S5,
Execution of the sound effect is permitted. In step S11, an audio device drive start signal is supplied to the audio device based on the determination result of "YES" in step S10. As a result, the driving of the sound device is started, and thereafter, the sound device is operated according to a mode predetermined by the selected program.
In step S12, the determination result is "NO" based on the contents of the program selected in step S5, and step S13 is omitted.

Second Information Processing Cycle In the second information processing cycle shown in FIG. 9, the start of the lighting effect is reserved until the specific acoustic information at the end of the preamble of the music by the audio device is confirmed. The contents of the processing in each step are as follows. That is, the second information processing cycle is continued until a specific sound according to the set condition is obtained.

In step S1, the use of the acoustic information among the coordinate information and the acoustic information of the moving object used as the cue signal is determined, and the non-use of the coordinate information is determined. Depending on the content of this decision, step S2 and step S6
Is controlled. In step S2, step S1
Since the use of the coordinate information is denied from the result, the determination result is "NO", so that the subsequent steps S3 to S5 are omitted, and the process proceeds to step S6. In step S6, it is determined whether or not the acoustic information is used as the cue signal. Since the acoustic information is used in the second information processing cycle of this effect example, the determination result is "YE
S ".

In step S7, acquisition of acoustic information is performed based on the result of step S6. Step S8
Then, since the specific acoustic information cannot be obtained until the prelude ends, the determination result is "NO", and step S9 is omitted based on the determination result of step S8, and the process proceeds to step S10. In step S10, the determination result is "NO" from the result of step S1, and step S11 is omitted. In step S12, step S
From the result of No. 1, the judgment result is “NO”, and step S1
Step 3 is omitted, and the process returns to step S1.

Third Information Processing Cycle In a third information processing cycle shown in FIG. 10, specific acoustic information at the time when the preamble of the music by the audio device ends is acquired, and this is used as a cue signal to produce a lighting effect. This is a process for starting, and the content of the process in each step is as follows.

Steps S1 to S7 correspond to the second
The same processing as in the information processing cycle is executed. In step S8, a specific sound at the time when the prelude ends is acquired in step S7, and the determination result is “YE
S ". In step S9, a program is selected. In step S10, the determination result is "NO" from the result of step S1, and step S11 is omitted.

In step S12, the result of determination in step S8 is "YES", and execution of the lighting effect is permitted. In step S13, “Y” in step S12
In response to the determination result of “ES”, a lighting device drive start signal is supplied to the lighting device. As a result, the driving of the lighting device is started, and thereafter, the lighting device is operated according to the mode defined in the program selected in step S9.

By executing the above information processing cycle, the intended effect can be achieved very accurately and easily.

FIG. 11 is an explanatory diagram showing an information processing cycle of an example of an effect in which a lighting effect for automatically illuminating a singer is illuminated in the third information processing cycle for performing the stage effect. In this information processing cycle, steps S121, S122,
Step S14 and step S15 are added.

Step S121 If the permission to start the lighting effect is transmitted from step S12, the process proceeds to step S121.
This is a step in which it is determined whether or not the program selected in step 9 includes a singer's automatic tracking illumination. If the decision result in the step S121 is "NO", a lighting device drive start signal is outputted in a step S13, and the processing is the same as that in the third information processing cycle. Step S122 In the determination in step S12, when the availability of the drive start signal of the lighting device is "NO", it is a step in which whether or not the program includes automatic tracking lighting of the singer is determined. Step S14 Step S121 or Step S1
This is a step of acquiring coordinate information for automatic tracking illumination when the determination result at 22 is “YES”. Step S15 This is a step of supplying a control signal to the illumination direction control mechanism of the illumination device in order to execute automatic tracking illumination based on the coordinate information acquired in step S14.

In the third information processing cycle, if "YES" is output as a result of the determination in step S12 and the lighting effect is started once, the lighting effect unit is terminated until one scene, which is the unit of the lighting effect, or the next time. Until the trigger is performed again by the cue signal, the result of the determination in step S12 is always “NO”. Therefore, in this information processing cycle, in step S122, the same processing as in step S121 is executed. Then, if the result of the determination is "YES", steps S14 and S15 are executed.

According to such a procedure, while a specific lighting effect is being executed, a special lighting effect such as automatic tracking lighting of a singer can be executed based on the position of a moving object. That is, the lighting device has a special function as a rendering device in that not only control of the driving state, that is, control of the lighting state, but also control of the lighting direction is an important control factor, and furthermore, control of the lighting direction. In, the position of the moving object is always an important factor. Therefore, in the present invention, it is possible to control the operation of a specific lighting device while maintaining a specific relationship with another staging device (this may be a lighting device). Therefore, control in a complicated manner can be executed very easily.

Although the embodiments of the present invention have been described in detail in the case where a lighting device and an audio device are used as the directing device, in the present invention, if various directing devices are installed in the theater, it is possible to obtain the desired effect. The start of the driving can be controlled by designating an appropriate one in accordance with the position of the moving object as a basic cue signal. It is also possible to install a plurality of effect devices of the same type and control each of them in the same manner.

Further, when a plurality of the same type of effect devices or a plurality of different effect devices are used, it is possible to control each of the effect devices in a state where the mutual relationship satisfies a specific condition. , And various effects can be executed in combination. In particular, in this case, the driving of each effect device can be controlled in consideration of the driving priority.

In the present invention, there may be a plurality of moving objects from which coordinate information is to be obtained. In this case, an appropriate method is applied to identify each moving object. For example, a plurality of radio wave signals R having specific frequencies different from each other are arranged at appropriate time intervals so as to identify individual ones of the plurality of ultrasonic transmitters and to designate a specific ultrasonic transmitter to start its operation. You can make it send.

According to the stage production performance method of the present invention, the position of a moving object that moves irregularly on the stage can be used as a basic cue signal as the moving object moves. Based on the standard, it is possible to automatically start the driving of various production devices operated according to a predetermined production program, so that the intended stage production effect can be provided with a large degree of freedom and sufficiently high reproducibility. Can be reliably achieved. As a result, in performing the stage performance, it is possible to greatly omit the operation of producing various and complicated cue signals that the producer should do,
The producer's labor can be greatly reduced, and a special operator is not required for each production device.
Even a complicated and large-scale stage production can be easily and accurately performed.
