Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a storage dimming device that dims a plurality of lighting loads based on dimming data stored in advance in a memory, and more specifically, The present invention relates to a storage dimming device that is suitably used when modifying optical data.

In conventional technology-a, multiple lighting loads are used on stages, studios, etc. to perform lighting effects, etc., and these are individually controlled for each predetermined group of multiple lighting loads (hereinafter referred to as a channel). The dimming level is centrally controlled in a control room, etc. There are two main types of dimming devices for performing dimming control such as setting the lighting levels of multiple lighting loads and switching the lighting levels for each scene to be produced (hereinafter referred to as a scene). method is used.

One of these, the manual type, has one stage of multiple preset faders that correspond to multiple lighting loads (channels) that each scene has, and a preset fader that sets the dimming level for each scene. A plurality of stages are provided, and each stage consisting of the preset faders is manually cross-faded to transition from the current scene to the next scene and perform scene change.

Another method is to store the dimming level set in advance for each scene in a storage means during rehearsals, etc., and during the actual performance, the stored contents are sequentially read out and the dimming level is adjusted based on the reproduced dimming level data. Performs light control. In such a storage light control device, the effort of manually performing the operations is reduced, and the operability is improved.

FIG. 5 shows a dimming operation console 1 provided in a memory dimming device capable of performing manual dimming control and memory dimming control described above.
FIG. A plurality of dimmers are connected to the operator console 1, a plurality of lighting loads are connected to each dimmer, and each channel is controlled to each dimming level set by the operator console 1.

The console 1 is provided with multiple rows of faders corresponding to each channel of the lighting load, and are individually associated with each scene to form a multiple stage preset fader 2. In addition, the console 1 is equipped with controls to perform fade-in and fade-out operations of the dimming level between scenes assigned to each stage of the preset fader 2.
Cross faders 3 are arranged in parallel so that scales of dimming levels increase and decrease in opposite directions.

That is, in the crossfader 3, when the operation piece 3a corresponding to the A scene is set at the scale 100% position and the operation piece 3b corresponding to the B scene is set at the scale position 0%, for example, the scene number 123 is set. When a scene is changed from A scene to B scene I with scene number 124, the operator displaces the operating pieces 3a and 3b in the same direction toward the bottom of the drawing, and moves the operating piece 3a to the scale 0. By moving the operation piece 3b to the 100% position on the scale, the scene change from scene A to scene B can be smoothly performed. At this time, the gene number 125 of the next scene displayed on the scene after scene display section 17 is displayed on the A sheet display section 15, and the display on the scene after scene display section 17 further changes to the next scene number 126.

In the same way, when the gene conversion from the B scene to the A scene is performed, the next scene number in the next scene display section 17 is displayed on the B sheet display section 16, and the next scene number is further displayed on the next scene display section 17. be done.

Further, the console 1 is provided with a stage selection push button 4 for selecting the stage on which the preset fader 2 is operated, and a number key 5 for inputting scene numbers, channel numbers for each scene, and the like.

Conventionally, as a method for storing dimming data for each scene in a memory dimming device, the dimming level for each channel in each scene is displayed on a display device 6 etc. by operating a number key 5 or the like in advance. While doing so, roughly set the settings and memorize them. Next, based on this stored dimming data, a method is adopted in which the dimming level is corrected and stored while actually lighting the lighting load.

As a modification method, a method called a modified matching method is being explored. That is, when the scene number to be corrected is specified using the numeric key 5 and the stored dimming level is in the correction mode where it can be corrected, a predetermined, for example, first stage (lower stage) fader of the Brisesoto fader 2 is pressed. is used to make the fader level correspond to the stored dimming level.

In the preset fader 2, if the level set by the fader and the stored dimming level do not match, a correction match indicator light corresponding to the number of faders in each stage of the preset fader 2 is provided. 7
does not light up, and even if the fader is tif'P, the level set by the fader will not be stored as the dimming level.

On the other hand, after the level of the operated fader matches the dimming level stored in advance for the lighting load associated with the fader, the correction match indicator light 7 lights up, and the correction is possible. In this correctable state, the level set by operating the fader is newly stored as a dimming level, and the dimming level of the corresponding lighting load is corrected.

The operating procedure for modifying an arbitrary scene is to first operate the modification mode key 8 on the console 1, and input the scene number to be modified using the number keys 5.

As a result, the inputted scene number is displayed on the memory/modification scene number display section 9. Next, when the arbitrary scene modification key 10 is operated, the dimming level of the corresponding scene can be modified. In this state, as described above, the dimming level for each channel of the scene is corrected using the preset fader 2 and stored.

On the other hand, in order to modify the dimming levels of all the lighting loads currently being reproduced, the user operates the modification mode key 8 and then operates, for example, the A modification key 11 corresponding to the current scene being reproduced. As a result, the dimming level of the current scene currently being played, for example, the A scene with scene number 123, can be corrected and stored. At the same time, the lighting load is dimmed and controlled at the dimming level set by operating the preset fader 2.

FIG. 6 is a flowchart for explaining a processing program that is executed at fixed time intervals in the processing section of the storage dimming device when the dimming level is corrected. Proceeding from step n1 to step n2, the level Pffi(
i) is read.

In step n3, a preset status MODE is determined by operating the correction mode key 8 of the console 1 or the like. If MODE=O, it is determined that the correction mode is not in progress, and the process proceeds to step n13.

When MODE-11-0 is determined in step n3, the process proceeds to steps n4 to n12, and the following process is performed while sequentially incrementing channel number i from i=1 to i=m.

In step n5, the value of the flag FLG(i) set corresponding to channel number i is determined.

That is, before the state in the correction mode is determined in step n3, the flag FLG(i) is cleared to O in advance, and the process proceeds to step n6.

In step n6, the dimming level Ml (i) of channel number i stored in advance in the memory and the fader level Pf (
i) is compared with zero level MZ(i), Pl(i
), the flag FLG(i) is set to 1 in step n7, and the process proceeds to step nil.

In step n11, the channel number i is the total number of channels m
Alternatively, it is determined whether the maximum number m of faders has been exceeded. If this judgment is affirmative, that is, if the channel number i is less than or equal to the total number of channels m, the channel number i is incremented in step n12, and then the process returns to step n5.

Similarly, when the processes from step n5 to step n12 are performed for each channel number i, the determination at step nil is denied and the process proceeds to step n13, where other processes related to dimming control are performed and the present processing program ends. finish.

Such processing is repeated at predetermined fixed time intervals. At this time, when the fader level Pl (i) of the operated preset fader 2 matches the dimming level Ml (i) stored in advance, the corresponding flag is set to FLG(i)=1.

That is, the process proceeds to step n8 based on the judgment in step n5 during the next process performed after setting the flag in step n7. In step n8, the level I'l! set by the preset fader 2! (i) is stored in memory as the dimming level M1 (i) of channel number i of the scene to be modified.

In step n9, it is determined whether the scene being modified is currently being played. This determination is made, for example, by detecting the operating state of the A correction key 11, the B correction key 12, or the optional scene correction key 10 operated on the console 1 when entering the correction mode.

If the judgment in step n9 is affirmative, step nlo
In step n2, the light control level is read out from the storage area of the memory where the dimming level is stored in advance in order to play back the scene being modified, and is read out and stored in the playback area of the memory in order to perform the dimming control. The fader level is stored.

As a result, the same dimming level Pl(i) as the previously stored dimming data and the dimming data stored and modified in step n8 is read out, and the lighting load is energized and modified based on this. Dimming levels are played back in real time.

In this way, modifying the dimming data using the modification matching method described above is extremely difficult because the fader numbers 1 to m of the preset fader 2, which are operated during the correction period, correspond to the newly set dimming level. This is an easy-to-understand and easy-to-operate correction method.

Problems to be Solved by the Invention In the correction matching method described above, when correcting the dimming level while playing, it is necessary to set the crossfader 3 to indicate whether the current scene currently being played is the A scene or the B scene. The user must enter the correction mode by operating the corresponding correction keys 11 and 12 based on the playback status indicators 13 and 14, which are lit according to the scene being played. The problem is that it is complicated.

In addition, the scene that can be modified by operating the preset fader 2 is displayed on the scene number display section 18, and is the current scene selected using the modification keys 11 and 12, or input using the modification key 19 and the numeric key 5. This is an arbitrary scene displayed on the stored/modified scene number display section 9.

Therefore, the level display section 20 where the dimming level is displayed
In this case, only the dimming level of the lighting load corresponding to the fader of the selected level of preset fader 2 is displayed for one scene, and the current scene to be modified or any specified scene, There is a problem in that it is not possible to compare and correct the dimming levels of the previous scene or the next scene that are temporally preceding or following the scene.

Furthermore, although it is conceivable to use all stages of preset fader 2 to correct the dimming level including the scenes before and after the scene to be corrected, the number of faders that the operator can operate simultaneously to make corrections. Although there are only about ten faders, for example, the number of faders at each stage is m = 120.
In order to display the coincidence state between the pre-stored dimming level of all the faders and the level set by the fader, a correction coincidence indicator light 7 is added corresponding to each of the faders of the preset fader 2. This results in an increase in the number of parts.

In addition, when making corrections that include the scenes before and after the current scene or any arbitrary scene, the process shown in Figure 6 is performed for all faders in all stages of preset fader 2.
Therefore, it takes time to correct the dimming level. Therefore, there is a problem in that it is difficult to reproduce the scene in real time using the modified dimming level.

An object of the present invention is to store a memory that can quickly modify the dimming level of the scene currently being played or a specified scene while considering the relationship with the dimming levels of the previous scene and the next scene. An object of the present invention is to provide a light control device.

Means for Solving the Problems The present invention provides: a dimming load that is divided into one or a plurality of categories; a storage means in which dimming data for each division of the dimming load is stored in chronological order; and a dimming load. an input section in which a plurality of input means for inputting dimming data corresponding to each category are provided over a plurality of columns; The storage dimming device is characterized in that a sub-sequence of range input means is set, and dimming data of the corresponding division of the dimming load is modified over a plurality of times along a time series.

Effect According to the present invention, the dimming load is divided into one or more parts. In the input section, a plurality of input means are provided in a plurality of rows, and dimming data corresponding to each division of the dimming load can be input. The input dimming data is stored in the storage means in chronological order. Therefore, a predetermined dimming level can be reproduced by reading the dimming data stored in advance in the storage means in chronological order and controlling the dimming load based on the read dimming data. .

Furthermore, when modifying the dimming data stored in the storage means, a partial sequence of input means within a predetermined range is set in each input means column, and the dimming data is modified for each partial sequence. Accordingly, the dimming data of the corresponding division of the dimming load can be corrected over a plurality of times along the time series.

By setting partial columns in each input method column in this way, multiple pieces of dimming data along the time series can be corrected. It becomes possible to modify optical data.

FIG. 2 shows the operation panel 21 of the operation section 42 and the display section 4.
1 is a diagram showing a display section W26 of No. 1. FIG. The operation panel 21 includes preset faders 22 provided in multiple stages,
Crossfader 2 for performing crossfade operations
3. A number key 25 for inputting scene numbers, channel numbers, etc., and a correction key 39a to be operated when correcting dimming data are provided. Further, the operation panel 21 is provided with a changeover switch 47 regarding a correction method.

The preset fader 22 is composed of multiple stages (three stages in this embodiment), and each stage can be assigned to correspond to a plurality of scenes in time series to set or modify dimming data. In particular, in this embodiment, the preset fader 2
2, each fader (number 1, 2...
, m-1, m, m=120), a correction coincidence indicator light 27 consisting of a light emitting diode or the like is provided,
A level display section 40 that digitally displays the level set by the fader of each stage of the preset fader 22 is provided at the stage (upper stage). Each of these stages of the preset fader 22 is selectively associated with a dimming level for each channel using keys P1 to P3 of a stage selection pushbutton 24, which will be described later.

The crossfader 23 is composed of a pair of faders whose level scales are set in opposite directions from 0% to 100%, and by operating the operation pieces 23a and 23b simultaneously in the same direction, the scene number can be changed. Display section 38
You can cross-fade between the A scene and B scene displayed on the screen. As a result, at least one of the reproduction status indicator lights 33 and 34 corresponding to the scene to be reproduced is lit.

The scene number display section 38 displays each corresponding scene number of the dimming data to be reproduced or stored sequentially in chronological order. For example, if the current scene number 123 is A
When displayed on the scene number display section 35, the next scene number 124 is displayed on the B scene number display section 36, and the next scene number 125 is displayed one after another on the scene number display section 37.

The stage selection pushbutton 24 is operated when assigning each channel of the scene whose dimming level is to be set to the fader of each stage of the crossfader 22 according to the display on each scene number display section 35 and 36 of the scene number display section 38. be done. For example, if you want to assign scene A to the first stage of the preset fader 22, press button P1 in row A of the stage selection pushbuttons 24, if you want to assign it to the second stage, press button P2, and if you want to assign it to the third stage, press button P3. operate each. In the case of scene B, the push buttons P1 to P3 in row B are operated in the same manner as described above. Each of the push buttons M in columns A and B is operated when assigning each stage of the preset fader 22 to an arbitrary pre-stored gene designated by the number key 25, as will be described later.

The numeric keys 25 are used to input scene numbers and dimming data for storing dimming data, and the inputted scene numbers are displayed on the record+tJ/corrected scene number display section 29, and are displayed for each channel. The correspondingly set dimming level is displayed on the display device 26 or the like.

Next, a description will be given of the operating procedure when modifying the dimming data stored in advance using the operating panel 21. When modifying the dimming data of the lighting load currently being reproduced, -1 first operates the modification mode key 27 of the modification keys 39a. Next, if you operate the correction key 31 without specifying a scene number, the A scene number display section 35 of the scene number display section 38 will display the current scene number currently being played, and the B scene number display section 36 will display the current scene number currently being played. The next scene number is displayed, and further scene numbers are displayed one after another in the scene number display section 37 one after another. In addition, in the preset fader 22, each channel of the A scene is assigned to each fader on the first stage (lower stage), and each channel of the B scene is assigned to the second stage (middle stage),
Scenes are assigned one after another to the third row (upper row).

On the other hand, when modifying the pre-stored dimming data of an arbitrary scene, the modification mode key 27 is first operated. Next, operate the number key 25 to specify the scene number to be corrected, and operate the correction key 31. /The specified scene number is displayed in the modified scene number display section 29. In the preset fader 22, each channel of the specified scene is assigned to each fader on the second stage, the scene immediately before the specified scene is assigned to the first stage, and the fader on the third stage is assigned a channel of the specified scene. The next scene is assigned.

In this way, multiple scenes in chronological order, including the scene being played or the specified scene, are assigned to each stage of the preset fader 22, so each scene is The dimming level can be stored or modified for each channel.

In this embodiment, when modifying the stored dimming data, the number of channels BN in the range to be modified (for example, BN = 40) is divided into one group, and the A corresponding to each group is divided into one group. When a scene, a B scene, one scene after another, or a scene number is specified, corrections of the previous scene, the specified scene, and the next scene are assigned to each stage of the preset fader 22.

That is, the channel number KN at which the dimming data correction starts is determined in advance, and the correction of the A scene or the previous scene corresponds to each of the 40 channels from the KNijth fader on the first stage of the preset fader 22. This can be done using a fader. To modify the B scene or the specified scene, you can use the 40 faders from the KNth fader on the second stage to modify 40 channels, and in the same way, on the third stage, you can modify the scenes one after another or the KNth channel of the next scene. Correctly, corrections are made for 40 channels.

At this time, for example, for each channel of the A scene assigned to the first stage preset fader 22,
The correction match indicator lights 27 and level display sections 40 of channel numbers 1 to 40 are used to display the match of correction levels and the dimming level.

Further, in the B gene, the correction match indicator lights 27 and level display sections 40 corresponding to the 40 channels starting from the assigned correction start channel number KN are used.

Further, for the successive scenes set on the third stage of the preset fader 22, the match state of the correction level and the dimming level are checked using the correction match indicator 27 and level display section 40 corresponding to channel numbers 81 to 120. be exposed.

40 from the correction start channel number KN as described above.
Once the correction of the dimming data for the channels A scene, B scene, and one scene after another is completed, the correction number feed key 32 of the correction key 39a is operated to assign it to each stage of the preset fader 22. Change the channel by increasing or decreasing the start channel number KN by 40, for example,
Modifications can be made to the dimming data for other channels.

FIG. 3 is a diagram showing the contents stored in the reproduction memory 44 and the working memory 43, respectively. A correction start channel number KN, a correction channel number BN, etc. are set in advance in the storage unit 49, and when a gene number j to be corrected is specified by the operation unit 42, for example,
Scene numbers (j-1) to (j+
1) and the channel number Kn~(KN+BN-1>), the dimming level data MIA(i), Mj!m(i), MIJ(
i) (i=Kn to KN+-BN-1) are transferred from the reproduction memory 44 to the working memory 43 in FIG. 2 (2>) and stored therein.

The dimming data stored in the working memory 43 is read out from the working memory 43 in the order of each scene number according to the time series, and is sent to each dimmer from 1 to K via the calculation/signal output section 46.
given to m. Furthermore, when the dimming data stored in the operation section 42 is corrected, the preset fader 2
The dimming level set in 2 is temporarily stored in working memory 4.
The tombs are stored according to the scene number in the store area of 3,
It is transferred to the corresponding store chain acid in the reproduction memory 44 and stored. In this way, the dimming data stored in advance can be modified.

FIG. 4 is a flowchart for explaining processing operations related to modification of dimming data according to the present invention. When proceeding from step m1 to step m2, preset fader 2
The level Pi'(i
) is read.

In step m3, the status MO indicating that the modification mode is in progress is
It is determined whether DE=O or not. In the case of MOD E-〇, it is determined that the modification mode is not in progress, and the process proceeds to step n15.
Proceed to. When it is determined in step m3 that the correction mode is in effect, in steps m4 to m12, the channel number i is set to a pre-specified correction start channel number K, N, and the number of correction channels BN. Then, the following processing is performed while sequentially incrementing the channel number i.

In step m5, a modified match flag F L G1 (i) is determined, which indicates whether the level set at the first stage of the preset fader 2 matches the stored dimming level. If flag FLGI(i)=0, step m
Proceeding to step 6, the dimming level MN, (i) of the channel number i of the A scene being played back is compared with the level P11 (i) set by the corresponding first stage preset fader 22. (i) and pH(i), in step m7 FLGl(i)-1
After that, the process proceeds to step mll, where it is determined whether the channel number i exceeds the modification end channel number (KN+BN-1) determined by the modification start channel number KN and the modification channel number BN.

If this judgment is affirmed, the channel number i is incremented in step m12, and then the process returns to step m5.

In step m5, if it is determined that FLGI(i>=1), in step m8, the level P1 of the fader corresponding to the channel number i of the first stage preset fader 2
1(i) is stored in the playback memory 44 as the dimming level M I A
(z).

In step m9, it is determined whether the scene being modified is currently being played. This determination is made based on, for example, the operation state of the correction key 39a on the operation panel 21. If the judgment in step m9 is negative, the process proceeds to step m11, and if the judgment is affirmative, the process proceeds to step mll after processing in step mIO.

In step mlo, the corrected fader level P11(i) is stored in the storage area of the working memory 43 corresponding to the corrected scene.

Thereby, the lighting load is dimmed and controlled based on the fader level P11(i) stored in the working memory 43, so that the corrected dimming level is reproduced in real time.

If the judgment in step mll is negative, step m13
In step m13, the preset fader 22
The modification of the B scene using the second stage is carried out in the same manner as steps m4 to m12 described above, which are indicated by reference numeral 50. In this process, a flag FLG2(i) indicating a corrected matching state set using the second stage of the fader fader 22 is used, and the set fader level P12(i) is set to the dimming level M1. (i,).

In step m14, the third stage of the preset fader 22 is used to modify the scenes one after another.

In this process, FLG3(i> indicating the corrected matching state when the third stage of the preset fader 22 is used is used, and the set fader level P13(i) is successively adjusted to the dimming level M/, ( i).

In step m15, other processes related to dimming control are performed, and then the present processing program ends. The above-mentioned process is repeated at predetermined intervals, whereby the level set with the preset fader 22 of the operation panel 21 is stored as a new dimming level in the playback memory 44, and the dimming data is corrected. be done.

As explained above, according to the present embodiment, multiple corrections can be made in chronological order without reducing the ability of the operation console 39 to correct the dimming date and night, and without adding the correction match indicator 27 or the like. It is possible to modify the dimming data for multiple scenes at the same time. Therefore, the dimming data can be corrected while checking not only the scene for which the dimming data is to be corrected, but also the interrelationship with the dimming data of adjacent scenes temporally before and after that scene. Improved operability and convenience. In particular, the present invention is effective in making corrections while actually reproducing stored dimming data.

As another embodiment of the present invention, the conventional A shown in FIG.
The correction key 11 and the B correction key 12 are also provided on the operation panel 21 of this embodiment, and a changeover switch 47 provided on the operation section 42 is used to switch between the conventional correction method and the correction according to the present invention. Accordingly, the dimming data may be corrected using a conventional correction method.

Further, in this embodiment, in each stage of the preset fader 22, when the number of faders corresponding to the channels m = 120, the number of modified channels BN = 40, and the A scene, B scene, and Although the total number of channels that can be modified at the same time in one scene after another is set to correspond to 120 channels, the modification start channel number KN and the number of modification channels B are not limited to this.
N may be any other appropriately determined value as long as it divides the preset fader 22 according to each scene in chronological order.

Further, the correction number sending key 32 in this embodiment is operated (+
-Although the modification start channel number KN is increased or decreased by 40 each time, it may be increased or decreased by any other number.

Effects of the Invention According to the present invention, when modifying the dimming data in the storage means, sub-sequences of input means within a predetermined range are set in each input means column, and are divided into one or a plurality of sub-sequences in advance. Since the dimming data of the division corresponding to the partial sequence of the dimming load is corrected over multiple time series, the dimming data can be corrected while understanding the temporal relationship. I can do it. Therefore, the operability and convenience regarding dimming control including correction of stored dimming data is improved, and accurate dimming control can be performed.
