<Functional configuration>
(1) System control device (light source device)
The functional configuration of the system controller 11 of the light source device 10 will be described with reference to FIG. The system control device 11 includes a transmission / reception unit 110, a distribution determination unit 120, and a supply control unit 130. These functions are realized by reading out one or more programs stored in the ROM 113 and executing them by the CPU 111. The system control device 11 also includes an information storage unit 140. The information storage unit 140 is realized by the storage 114, for example.

  The transmission / reception unit 110 transmits / receives a signal to / from the projection device 20 via the network 3. The transmission / reception unit 110 receives, from each of the projection devices 20, a signal including the identifier of the projection device 20 and the size of the projected image.

  The distribution determination unit 120 determines the amount of luminous energy to be distributed to each of the projection devices 20, based on the size of the projected image received from each of the projection devices 20. When determining the amount of luminous energy to be distributed, the distribution determination unit 120 refers to the correspondence management table 141, the luminous energy management table 142, and the light source capacity management table 143 held by the information storage unit 140. The information managed in each table will be described later.

  The supply control unit 130 operates the distribution device 15 so that the amount of the luminous energy determined by the distribution determination unit 120 is supplied to each of the projection devices 20. Thereby, the luminous energy supplied to the projection device 20 is appropriately adjusted.

  The information storage unit 140 stores various kinds of information necessary for the operation of the system control device 11. An example of the correspondence management table 141 stored in the information storage unit 140 is shown in FIG. 5A, an example of the luminous energy management table 142 is shown in FIG. 5B, and an example of the light source capacity management table 143 is shown in FIG. (C) of.

  The correspondence management table 141 is a table that stores the identifier of the optical fiber I / F 16 to which the projection device 20 is connected and the identifier of the projection device 20 in association with each other. When the priority is assigned to the projection device 20, the correspondence management table 141 may store the priority of the projection device 20. In the correspondence management table 141 of FIG. 5A, the identifier of the optical fiber I / F 16, the identifier of the projection device 20, and the priority of the projection device 20 are stored in association with each other. For example, the projection device 20 having the identifier “#A” of the projection device 20 is connected to the identifier “001” of the optical fiber I / F 16, and the priority of the projection device 20 is “high”.

  The light intensity energy management table 142 is a table that stores the size of the projected image and the required light intensity energy (lm) in association with each other. For example, the luminosity energy management table 142 of FIG. 5B indicates that the luminosity energy of 1,000 lm is required when the size of the projected image is 30 inches. The information storage unit 140 may manage the luminous intensity energy management table 142 of FIG. 5A and the luminous intensity energy corresponding to the size of the projected image with different granularity.

  The light source capacity management table 143 stores the identifier of the light source 14 and the luminous energy that can be supplied by the light source 14 in association with each other. For example, in the light source capacity management table 143 of FIG. 5C, the light intensity energy that can be supplied by the light source 14 having the “identifier 001” is “2,500 lm”, and the maximum value of the light intensity energy that can be supplied by the light source device 10 is Indicates that it is “6,000 lm”.

  When the transmission / reception unit 110 receives the size of the projected image from each of the projection devices 20, the distribution determination unit 120 refers to the luminous intensity energy management table 142 and specifies the required luminous intensity energy. Next, the distribution determination unit 120 refers to the correspondence management table 141 and identifies the identifier of the optical fiber I / F 16 that supplies the identified required luminous intensity energy.

  When the total value of the light intensity energy supplied to each of the projection devices 20 specified based on the light intensity energy management table 142 exceeds the maximum value of the light intensity energy that can be supplied by the light source device 10, the distribution determination unit 120 causes the correspondence management. The luminous energy supplied to each of the projection devices 20 may be adjusted based on the priority of the table 141. In this case, for example, the distribution determining unit 120 supplies the luminous energy required according to the size of the projected image to the projection device 20 whose priority is set to “high”, and the priority is “medium”. And the projection device 20 set to “low” may be supplied with less light intensity energy than required. At this time, the distribution determination unit 120 may make adjustment so that the lower the priority is, the larger the ratio or the amount of the reduced luminous energy is. Alternatively, the distribution determination unit 120 determines to stop the supply of the luminous intensity energy to any one of the projection devices 20 (for example, the projection device 20 connected last), and notifies that via the transmission / reception unit 110. You may.

  Further, in order to suppress the power consumption of the light source device 10, the distribution determination unit 120 may stop the light emission of any one of the light sources 14 when sufficient luminous energy can be supplied to each of the projection devices 20.

(2) Control device (projection device)
The functional configuration of the control device 21 of the projection device 20 will be described with reference to FIG. The control device 21 includes a transmission / reception unit 210, a size calculation unit 220, and a projection control unit 230. These functions are realized by reading out one or more programs stored in the ROM 213 and executing them by the CPU 211. The control device 21 also has an information storage unit 240. The information storage unit 240 is realized by the storage 214, for example.

  The transmission / reception unit 210 transmits / receives a signal to / from the light source device 10 via the network 3. The transmission / reception unit 210 transmits a signal including the identifier of the projection device 20 and the size of the projected image to the light source device 10.

  The size calculator 220 calculates the size of the projected image and notifies the light source device 10 of the calculated size of the projected image via the transmitter / receiver 210. For example, the size calculation unit 220 causes the camera 28 to capture a projected image on the projection surface 4 and acquires captured data. The size calculation unit 220 calculates the size of the projected image based on the captured data. For example, the size calculation unit 220 causes the distance measuring device 27 to measure the distance between the projection device 20 and the projection surface 4, and acquires the measurement result. The size calculator 220 calculates the size of the projected image from the measurement result and the angle of view when the projection optical system device 26 projects the image data.

  The projection control unit 230 controls the entire projection device 20. The projection control unit 230 controls the image generation device 25 and generates an image to be projected on the projection surface 4 based on the image data input from the terminal 30.

  The information storage unit 240 stores various data necessary for controlling the projection device 20. The information storage unit 240 may store image data. In this case, the projection control unit 230 reads the image data from the information storage unit 240 and causes the image generation device 25 to generate an image to be projected on the projection surface 4.

<Configuration example of projector system>
A configuration example of the projector system 1 according to the embodiment will be described with reference to FIGS. 7 and 8. The value of (b) of FIG. 5 is set in the luminous energy management table 142, and the value of (c) of FIG. 5 is set in the light source capacity management table 143.

  In FIG. 7, the light source device 10 is shown to be connected to the projection device 20A and the projection device 20B. The size calculation unit 220 of the projection device 20A calculates the size of the projection image on the projection surface 4A as 80 inches, and notifies the light source device 10 of the calculation result. Similarly, the size calculation unit 220 of the projection device 20B calculates the size of the projected image on the projection surface 4B as 50 inches, and notifies the light source device 10 of the calculation result.

  The distribution determination unit 120 of the light source device 10 refers to the light intensity energy management table 142 and determines to supply the projection device 20A with the light energy of 2,500 lm and the projection device 20B with the light energy of 2,000 lm. . The distribution determination unit 120 refers to the correspondence management table 141, specifies the optical fiber I / F 16 corresponding to the projection device 20A and the projection device 20B, and supplies the determined light intensity energy to the specified optical fiber I / F 16. The distribution device 15 is controlled as follows.

  In the example of FIG. 7, the light intensity energy that can be supplied by the light source device 10, that is, the total value of the light intensity energy that can be supplied by each of the light sources 14 (14A, 14B, 14C) is 6,000 lm. Since the total value of the luminous intensity energy that needs to be supplied to the projection device 20A and the projection device 20B is 4,500 lm, the distribution determination unit 120 suppresses the amount of the luminous intensity energy to be output. In this case, the necessary light intensity energy can be supplied by the light intensity energy output from the light source 14A and the light source 14B, so that the distribution determination unit 120 determines to stop the output of the light source 14C, for example. This makes it possible to reduce the power consumption of the light source device 10.

  Next, FIG. 8 will be described. FIG. 8 shows a state in which the light source device 10 is connected to the projection device 20A, the projection device 20B, and the projection device 20C. Here, it is assumed that the projection apparatus 20A is set to the priority "high", the projection apparatus 20B is set to the priority "medium", and the projection apparatus 20C is set to the priority "low".

  The size calculation unit 220 of the projection device 20A calculates the size of the projected image on the projection surface 4A as 100 inches, and notifies the light source device 10 of the calculation result. The size calculation unit 220 of the projection device 20B calculates the size of the projected image on the projection surface 4B as 80 inches, and notifies the light source device 10 of the calculation result. The size calculation unit 220 of the projection device 20C calculates the size of the projected image on the projection surface 4C as 30 inches, and notifies the light source device 10 of the calculation result.

  The distribution determining unit 120 of the light source device 10 refers to the light intensity energy management table 142 and needs to supply the projection device 20A with light intensity energy of 3,000 lm, and needs to supply the projection device 20B with light intensity energy of 2,500 lm. Therefore, it is determined that it is necessary to supply the projection device 20C with the luminous energy of 1,000 lm. Here, since the maximum luminous energy that can be supplied by the light source device 10 is 6,000 lm, the luminous energy of 500 lm is insufficient.

  In this case, the distribution determination unit 120 adjusts the luminous energy supplied to each of the projection devices 20 based on the priority. For example, the distribution determination unit 120 supplies 2,500 lm of light intensity energy to the projection device 20A having the priority “high”, and the projection device 20B having the priority “medium” has 90% of the required light intensity energy of 1: 1. It is determined that 800 lm of luminous energy is supplied and 700 lm of luminous energy, which is 70% of the required luminous energy, is supplied to the projector device 20C having the priority "low". As in the case of FIG. 7, the distribution determination unit 120 specifies the optical fiber I / F 16 corresponding to the projection device 20, and the distribution device 15 is supplied so that the determined light intensity energy is supplied to the specified optical fiber I / F 16. To control. By adjusting the supplied light intensity energy based on the attributes such as the priority of the projection device 20, it is possible to appropriately distribute the light intensity energy to each of the projection devices 20.

<Operating procedure>
(1) Projecting Device An operation procedure for calculating the size of a projected image by the projecting device 20 will be described with reference to FIG.

  In step S901, the size calculation unit 220 of the projection device 20 causes the distance measurement device 27 to measure the distance between the projection device 20 and the projection surface 4.

  In step S902, the size calculation unit 220 calculates the size of the projected image based on the measured distance. For example, the size calculator 220 calculates the size of the projected image based on the distance and the angle of view of the projection optical system device 26.

  In step S903, the size calculation unit 220 notifies the light source device 10 of the calculated size of the projected image via the transmission / reception unit 210.

  The light source device 10 determines the luminous energy to be supplied based on the notified size of the projected image.

(2) Light Source Device Next, with reference to FIG. 10, an operation procedure relating to the determination of the luminous energy supplied by the light source device 10 to the projection device 20 will be described. Here, it is assumed that the light source device 10 can supply luminous intensity energy to N (N is a natural number) projection devices 20, and each of the projection devices 20 is provided with any one of the device numbers 1 to N. . Further, it is assumed that the light source device 10 supplies a predetermined amount of light intensity energy to the projection device 20 to calculate the size of the projected image.

  In step S1001, the distribution determination unit 120 sets the device number N of the projection device 20 to be processed to 1.

  In step S1002, the distribution determination unit 120 starts the process for the projection device 20 having the device number N.

  In step S1003, the distribution determination unit 120 starts the timer T. The timer T is activated for a predetermined period.

  In step S1004, the distribution determination unit 120 determines whether or not the size of the projected image is received from the projection device 20 (N) while the timer T is running. When the size of the projected image is received (step S1004 Yes), the process proceeds to step S1005. On the other hand, if the size of the projected image is not received (step S1004 No), the process proceeds to step S1006.

  In step S1005, the distribution determination unit 120 refers to the luminous energy management table 142 and determines the luminous energy to be supplied to the projection device 20 (N).

  In step S1006, the distribution determination unit 120 stops the supply of the luminous energy to the projection device 20 (N).

  In step S1007, the distribution determination unit 120 increments the device number N by 1.

  In step S1008, the distribution determination unit 120 determines whether the device number N exceeds the maximum number connectable to the light source device 10. When the device number N exceeds the maximum number that can be connected to the light source device 10, the process proceeds to step S1009. On the other hand, if the device number N is less than or equal to the maximum number connectable to the light source device 10, the process returns to step S1002.

  In step S1009, the distribution determination unit 120 determines whether or not the total of the luminous energy determined to be supplied to each of the projection devices 20 is less than or equal to the maximum value (E_MAX) of the luminous energy that can be supplied by the light source device 10. . If it is less than or equal to E_MAX (Yes in step S1008), the process advances to step S1010. On the other hand, when it exceeds E_MAX (No in step S1008), the process proceeds to step S1011.

  In step S1010, the supply controller 130 controls the distributor 15 so that the determined luminous intensity energy is supplied to each of the projection devices 20.

  In step S1011, the distribution determination unit 120 adjusts the luminous energy supplied to each of the projection devices 20. For example, the distribution determination unit 120 refers to the correspondence management table 141 and adjusts the luminous energy supplied to each of the projection devices 20 based on the priority set in the projection devices 20.

  In step S1012, the supply control unit 130 controls the distribution device 15 so that the luminous intensity energy adjusted in step S1011 is supplied to each of the projection devices 20.

<Example of configuration of distributor>
Next, a configuration example of the distribution device 15 will be described with reference to FIG. As shown in FIG. 11, the distribution device 15 includes a light tunnel 151, relay lenses (152A and 152B), a polygon mirror 153, and a folding mirror 154.

  The light tunnel 151 is formed in a square tube shape by laminating plate glass or the like, for example. The light tunnel 151 multiplexes the light emitted from the light sources (14A, 14B, 14C) on the inner surface to uniformize the luminance distribution and guides the light to the relay lenses (152A, 152B).

  The relay lenses (152A, 152B) collect the light emitted from the light tunnel 151.

  The polygon mirror 153 rotates upon receiving an instruction from the system control device 11. The polygon mirror 153 reflects the light emitted from the relay lens 152 to the folding mirror 154.

  The folding mirror 154 reflects the light emitted from the polygon mirror 153 and makes it enter the optical fiber I / F (16A, 16B, 16C).

  The system control device 11 adjusts the rotation speed of the polygon mirror 153, and controls so that the light intensity energy determined by the distribution determination unit 120 enters each of the optical fibers I / F 16.

  The above-described configuration of the distribution device 15 is an example, and it goes without saying that the distribution device 15 can be realized with other configurations. For example, a half mirror that transmits half of the light intensity energy and reflects half of the light intensity energy may be used to adjust the light intensity energy incident on each of the optical fibers I / F 16. Further, the polygon mirror 153 and the half mirror may be combined to adjust the luminous energy incident on each of the optical fibers I / F 16. When adjusting the luminous energy incident on the optical fiber I / F 16 using the polygon mirror 153 or the like, there is a period during which no light is incident on the optical fiber I / F 16. Therefore, the system control device 11 controls the distribution device 15 so that the light intensity energy incident on the optical fiber I / F 16 is larger than the light intensity energy specified from the correspondence management table 141 by a predetermined amount.

[Other]
In the above-described embodiment, the case where the size of the projection image is calculated by the projection device 20 has been described, but the information necessary for the projection device 20 to calculate the size of the projection image (for example, the shooting data of the projection image and the distance).
