Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic performance control device, and in particular is capable of outputting time data indicating playback time as well as playback of an audio signal such as a compact disc (CD) playback device. The present invention relates to an automatic performance control device that enables time-series control of lighting equipment, a slide projector, etc. in accordance with the playback of an audio playback device.

[Prior Art] Conventionally, in theaters, science fairs, etc., automatic music performances have been used to enhance the performance effect by controlling the dimming of lighting equipment, advancing frames of a slide projector, or flashing strobe lights in time with music playback. Control devices are known. In such devices, music signals and control data for controlled objects, such as the dimming level of lighting equipment, are stored in a time-series manner on a magnetic tape with multiple tracks, and individual signals are recorded in synchronization with music playback. The controlled object was being controlled.

[Problems to be Solved by the Invention] However, in this conventional method, in order to record the dimming level and other control signals of lighting equipment in analog or digital format on magnetic tape, individual control data must be modified. Moreover, there is a problem that writing a new one is extremely complicated and difficult. In addition, noise in the reproduced signal, level fluctuation due to changes over time, or time lag in the reproduced signal between each track may sometimes cause control errors or lags in control time of the controlled object, making it impossible to perform accurate control. There was this inconvenience.

In view of the problems with the conventional type, an object of the present invention is to provide an automatic performance control device that allows writing and modification of control data to be extremely easy, and that accurately controls automatic performance without causing control errors or time lags. The goal is to make it possible.

[Means for Solving the Problems] The automatic performance control device according to the present invention includes a memory means for storing time-series control data for a controlled object such as a lighting equipment or a slide projector, and a memory means for storing time-series control data for a controlled object such as a lighting equipment or a slide projector. control means for controlling the controlled object in a time-series manner by comparing the generated control data with time data of an audio playback device capable of outputting time data, such as a CD playback device. . The memory means and control means are realized by, for example, a digital memory and a microprocessor, and an input device such as a keyboard is used to write control data into the memory means.

[Function] In the automatic performance control device described above, temporal control data for the lighting equipment and other controlled objects is written in advance into the memory means from, for example, the keyboard.

Then, by playing the CD with the CD playback device, the CD is played.
Comparing the temporal data obtained from the reproduction device with temporal control data stored in the memory means.

Based on this comparison, the control indicated by the temporal control data is performed on the corresponding controlled object at each time indicated by the temporal control data. In this way, dimming of the lighting equipment and various other controls are automatically performed in chronological order according to the playback by the CD playback device.

[Example] Hereinafter, the present invention will be explained in detail with reference to the drawings.

The accompanying drawings schematically show the configuration of an automatic performance control device according to an embodiment of the present invention. The device shown in the figure includes, for example, a memory and control section 2 composed of a microprocessor, a keyboard 4, a CRT display 6, a CD playback device 8,
Amplifier 10, speaker 12, dimmer 14, baton device 1
6, a slide projector 18, an effect device 20, etc. The CD playback device 8 plays back a compact disc (CD) 22 and generates time data DT, music signal MS, and the like. The dimmer 14 and the baton fixture 16 each control the illumination lamp 2 based on the control signal from the memory and the control unit 2.
4 and controls a motor 26 that moves the illumination lamp 24, for example, up and down. The slide projector 18 projects a predetermined slide, advances frames, etc. based on the memory and control signals from the control section 2.

Further, the effect device 20 is used to emit strobe light, project stars, generate fog, etc., for example.

In the automatic performance control device described above, the keyboard 4 is
Temporal control data for each controlled object such as the dimmer 14 is input into the memory and the memory of the control unit 2 using the CRT display 6 in accordance with each timing of music reproduction by the CD 22. The temporal control data may include, for example, the control amount of each controlled object, such as the absolute amount or amount of change in the dimming level, for each relative time or absolute time from the start of reproduction of the CD 22. Alternatively, it is also possible to specify, as temporal control data, that the control amount is changed from a certain time to another time according to a certain change gradient.

After the temporal control data is stored in the memory and control section 2 in this way, when the CD 22 is played back by the CD playback device 8, the music signal MS is generated based on the information contained in the CD 22, and the music signal MS is generated by the amplifier 10. Music etc. are played back from the speaker 12 via the speaker 12. Also at this time, C
The D reproducing device 8 also generates time data DT indicating the elapsed time from the start of reproducing the CD 22, for example, and inputs it to the memory and control section 2. The memory and control unit 2 compares this time data DT with time information included in pre-stored temporal control data, and when the two match, generates a control signal based on the control information included in the temporal control data. It is created and inputted to the controlled object, for example, the dimmer 14. Dimmer 14
performs dimming control of the illumination lamp 24 based on the input control signal, and feeds back information indicating the control state to the memory and the control unit 2. This makes it possible for the memory and the control unit 2 to know the control status of the illumination lamp 24 and the like, and to appropriately control each controlled object. Further, based on such information, the memory and control unit 2 can also display the control status of each illumination lamp 24 and other control objects on the CRT display 6. As described above, the dimmer 14, the baton device 16, the slide projector 18, the effect device 20, etc. are automatically controlled in chronological order according to the playback of the CD 22.

In addition, in the above-mentioned embodiment, the case where each controlled object is controlled based on the time data obtained from the CD playback device has been explained, but as long as the playback device is capable of generating time data, various kinds of playback devices, such as digital Tape recorder,
A VTR or video disk device can be used.

[Effects of the Invention] As described above, according to the present invention, time-series control of each controlled object is performed by comparing time data obtained from a CD playback device or the like with time-based control data stored in a memory device in advance. As a result, control of each controlled object is performed extremely accurately in time, and control is performed appropriately without being adversely affected by fluctuations in control level or noise. Furthermore, it is possible to store, ie, prepare and modify control data for each controlled object extremely easily, and excellent performance effects can be achieved.
