[0007] Hereinafter, with reference to the drawings, a description will be given of the lighting control system 1000 and a control method for the lighting control system 1000. First, with reference to FIG.

[0008] As shown in FIG. 1, the lighting control system 1000 includes a projector 100 as a display device, and a lighting device 200.

[0009] The lighting control system 1000 is a system that can enhance the sense of realism by, for example, roughly matching the display color of the projection image 310 projected from the projector 100 with the emission color of the lighting device 200. Note that the lighting control system 1000 is not limited to matching the emission colors, and may use different emission colors or may change the emission color randomly.

[0010] The projector 100 includes a projection unit 140 for projecting image information input from outside onto a projection surface 300. A projection image 310 based on the image information is displayed on the projection surface 300. Examples of the projection surface 300 include a wall in a room, a screen, and a whiteboard.

[0011] The illumination device 200 has a light-emitting unit 250 that emits light corresponding to the projected image 310. The light-emitting unit 250 changes color, brightness, etc. based on gradation data. The light-emitting unit 250 has a light-emitting element such as an LED (Light Emitting Diode). For example, the light-emitting unit 250 preferably has one or more red LEDs that emit red light, one or more green LEDs that emit green light, and one or more blue LEDs that emit blue light. Note that the light-emitting unit 250 is not limited to an LED and may be a light bulb.

[0012] Next, the electrical configuration of the lighting control system 1000 will be described with reference to FIG.

[0013] As described above, the lighting control system 1000 includes the projector 100 and the lighting device 200. The lighting device 200 includes, for example, a first lighting device 200A and a second lighting device 200B.

[0014] The projector 100 and the two lighting devices 200A and 200B are wirelessly connected via a wireless router 350. The wireless router 350 is, for example, a Wi-Fi (registered trademark) router. The projector 100 and the lighting devices 200 are paired using the Matter protocol.

[0015] Illumination devices 200A and 200B emit light based on the gradation data obtained from projector 100. For example, first illumination device 200A emits light in the same color as the color of the left image area of ​​projection image 310 based on the gradation data. Second illumination device 200B emits light in the same color as the color of the right image area of ​​projection image 310 based on the gradation data (see FIG. 1).

[0016] By configuring the lighting control system 1000 in this way, it becomes possible to send commands directly from the projector 100 to the lighting devices 200A and 200B, thereby reducing the risk of delays.

[0017] Next, the electrical configuration of the lighting control system 1000 of the first embodiment will be described in detail with reference to FIG.

[0018] The lighting control system 1000 includes the projector 100 and the lighting device 200 as described above.

[0019] The projector 100 has a first control unit 110, a first storage unit 120, a first communication unit 130, a projection unit 140, a video data acquisition unit 150, a first image processing unit 160, and a first display unit 170.

[0020] The first control unit 110 is configured to include one or more processors, and operates in accordance with a control program stored in the first storage unit 120 to perform overall control of the operation of the projector 100 .

[0021] The first storage unit 120 is configured with memories such as RAM (Random Access Memory) and ROM (Read Only Memory). The RAM is used to temporarily store various data and the like, and the ROM stores control programs and control data for controlling the operation of the projector 100. The first storage unit 120 also stores image area information indicating which part of the image area of ​​the entire projected image 310 the image area corresponds to.

[0022] The first communication unit 130 transmits and receives signals to and from the second communication unit 230 of the lighting device 200. Specifically, the first communication unit 130 transmits and receives signals to and from the second communication unit 230 of the first lighting device 200A that constitutes the lighting device 200, and to and from the second communication unit 230 of the second lighting device 200B that constitutes the lighting device 200.

[0023] Although not shown, the projection unit 140 is configured to include a light source, a liquid crystal light valve as a light modulation device, a projection optical system, a light valve driving unit, etc. The projection unit 140 modulates light emitted from the light source with the liquid crystal light valve to form image light, and projects this image light from the projection optical system which includes at least one of a lens and a mirror to display a projection image 310 on the projection surface 300.

[0024] The video data acquisition unit 150 acquires video data at a predetermined timing from the video data input to the projector 100.

[0025] The first image processing unit 160 executes each process based on instructions from the first control unit 110. The first image processing unit 160 sets gradation data based on the video data transmitted by the first control unit 110 and the image area information stored in the first storage unit 120.

[0026] The first display unit 170 includes a display panel such as an LCD (liquid crystal display), and displays, for example, a setting screen of the projector 100.

[0027] The lighting device 200 includes a second control unit 210, a second storage unit 220, a second communication unit 230, a second image processing unit 240, and a light emitting unit 250.

[0028] The second control unit 210 is configured to include one or more processors, and operates in accordance with a control program stored in the second storage unit 220 to comprehensively control the operation of the lighting device 200.

[0029] The second storage unit 220 is configured to include memories such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The RAM is used to temporarily store various data, and the ROM stores control programs and control data for controlling the operation of the lighting device 200.

[0030] The second communication unit 230 transmits and receives signals to and from the first communication unit 130 of the projector 100.

[0031] The second image processing unit 240 executes each process based on instructions from the second control unit 210. The second image processing unit 240 converts the gradation data sent from the projector 100 into light emission data that allows the light emitting unit 250 to emit light.

[0032] The light emitting unit 250 emits light based on the gradation data. The light emitting unit 250 changes brightness and color based on the gradation data. The light emitting unit 250 has a light emitting element such as an LED (Light Emitting Diode). For example, the light emitting unit 250 preferably has one or more red LEDs that emit red light, one or more green LEDs that emit green light, and one or more blue LEDs that emit blue light.

[0033] In this way, the projector 100 and the lighting device 200 are capable of wireless communication, the gradation data set by the projector 100 is transmitted to the lighting device 200, and the light-emitting section 250 of the lighting device 200 emits light based on the gradation data, so that the lighting device 200 can be controlled without using a dedicated device such as an MPU. Therefore, the configuration of the lighting control system 1000 can be simplified compared to when a dedicated device such as an MPU is used.

[0034] Next, a control method of the lighting control system 1000 will be described with reference to FIGS. 4, 5A, 5B, 6, and 7A to 7D.

[0035] First, a basic control method of the lighting control system 1000 will be described with reference to Figures 4, 5A, and 5B. Note that the control method of this embodiment describes a method for causing the first lighting device 200A on the left side to emit red light when the color of the left image area in the projected image 310 is red, for example, as shown in Figure 1.

[0036] 4, in step S11, image area information is stored. Specifically, the first control unit 110 of the projector 100 causes the first storage unit 120 to store image area information indicating that the left image area of ​​the entire projected image 310 is the target (see FIG. 5A).

[0037] In step S12, the video data is stored. Specifically, the first control unit 110 causes the video data acquisition unit 150 to acquire video data of the image area on the left side of the projection image 310.

[0038] In step S13, the video data is transmitted. Specifically, the first control unit 110 transmits the acquired video data to the first image processing unit 160.

[0039] In step S14, the gradation data is transmitted. Specifically, the first control unit 110 sets the gradation data in the first image processing unit 160 based on the video data and the image area information stored in the first storage unit 120, and transmits the gradation data to the first control unit 110.

[0040] In step S15, the gradation data is transmitted to the first illumination device 200A. Specifically, the first control unit 110 causes the first communication unit 130 to transmit the set gradation data to the second communication unit 230 of the first illumination device 200A, and also transmits the set gradation data to the second image processing unit 240.

[0041] In step S16, first illumination device 200A emits light. Specifically, as shown in FIG. 5B, second control unit 210 of first illumination device 200A causes light-emitting unit 250 to emit light based on the gradation data. For example, if the image area on the left side of projection image 310 is displayed in red, the light-emitting unit 250 emits light in the same red color. This enhances the sense of realism.

[0042] In this way, the projector 100 and the first illumination device 200A are capable of wireless communication, the gradation data set by the projector 100 is transmitted to the first illumination device 200A, and the light-emitting section 250 of the first illumination device 200A emits light based on the gradation data, so that the first illumination device 200A can be controlled without using a dedicated device such as an MPU, for example. Therefore, the configuration of the illumination control system 1000 can be simplified compared to when a dedicated device such as an MPU is used.

[0043] In step S14, the gradation data is set based on the video data and image area information, but this is not limited to this, and the gradation data may be set including setting information in addition to the video data and image area information.

[0044] Specifically, the setting information is, for example, a mode setting. Examples of the mode setting include theater mode, sports mode, and live mode. In theater mode, for example, the brightness of the first illumination device 200A is set to be darker. In sports mode, for example, the frame rate is increased and the update frequency of the gradation data is increased. In live mode, for example, the brightness of the first illumination device 200A is set to be brighter.

[0045] In this way, in addition to the video data and image area information, the gradation data is set including the setting information, so that, for example, it is possible to match the color displayed by the projector 100 with the color emitted by the lighting device 200, or to express the color, brightness, etc. of the lighting device 200 according to the theater mode, sports mode, or live mode.

[0046] Furthermore, the setting information is not limited to the mode setting, and may include a setting for the update frequency of the gradation data. In this way, the update frequency of the gradation data is set, so that the update frequency of the gradation data can be increased or decreased according to the frame rate, for example, as in sports mode. This allows for a spatial effect to be achieved.

[0047] Next, a control method of the lighting control system 1000, for example, a control method using a UI (User Interface) screen, will be described with reference to Fig. 6 and Fig. 7A to Fig. 7D. In this embodiment, a setting method using the first display unit 170 provided in the projector 100 will be described.

[0048] As described above, the projector 100 is paired with the lighting device 200, which is a Matter device, by using the Matter protocol. Matter is one of the control protocols. The projector 100 registers, i.e., is paired with, the lighting device 200 based on the identification code stored in the first storage unit 120.

[0049] 6, in step S21, a request to update image area information is accepted. Specifically, for example, the user touches first display section 170 or presses a selection button.

[0050] In step S22, a selection screen is displayed. Specifically, as shown in FIG. 7A, the first control unit 110 of the projector 100 causes the first display unit 170 to display a menu, i.e., a selection screen. The user selects, for example, "Set image area." This causes the first control unit 110 to cause the first display unit 170 to display a "Lighting device list" from which the lighting device 200 can be selected.

[0051] In step S23, the identification information is acquired. Specifically, the user selects the first illumination device 200A from the "illumination device list" as shown in Fig. 7B. As a result, the first control unit 110 acquires the identification information of the first illumination device 200A.

[0052] In step S24, an update screen is displayed. Specifically, first control unit 110 causes first display unit 170 to display an update screen for image area information. First, as shown in FIG. 7C, "image division," that is, the division ratio of projected image 310, is set. Here, for example, "1:2," that is, 1 vertically and 2 horizontally, is selected. This displays image area 171A on the left and image area 171B on the right.

[0053] Next, as shown in Fig. 7D, a selection is made as to whether to set left image area 171A or right image area 171B. Here, for example, left image area 171A is selected. That is, image area information is determined. In other words, the display color of the left area of ​​projection image 310 projected from projector 100 and the emission color of first illumination device 200A are made to match.

[0054] In step S25, image region information is acquired. In step S26, the image region information is updated. Specifically, first control unit 110 acquires the image region information, and stores the image region information in first storage unit 120 to update the information.

[0055] Thereafter, by performing the same processes as in steps S12 to S16 described above, first illumination device 200A emits light as shown in FIG. 5B. For example, if the image area on the left side of projected image 310 is displayed in red, first illumination device 200A emits light in the same red color. This enhances the sense of realism. Note that when second illumination device 200B is made to emit light in the same color as the image area on the right side of projected image 310 (see FIG. 1), projector 100 and second illumination device 200B are set in the same manner as the above method.

[0056] In this way, the gradation data is set using the first display unit 170 of the projector 100, so the color of the lighting device 200 can be set simply by operating the projector 100, without using any devices other than the projector 100 and the lighting device 200.

[0057] As described above, the lighting control system 1000 of the first embodiment is a lighting control system 1000 having a projector 100 including a first control unit 110, a first image processing unit 160, and a first memory unit 120, and a lighting device 200 including a second image processing unit 240 and a light-emitting unit 250 and capable of wireless communication with the projector, wherein the first memory unit 120 stores image area information, the first control unit 110 acquires video data and transmits the acquired video data to the first image processing unit 160, the first image processing unit 160 transmits gradation data set based on the video data and the image area information stored in the first memory unit 120 to the first control unit 110, the first control unit 110 transmits the gradation data to the second image processing unit 240, and the light-emitting unit 250 emits light based on the gradation data.

[0058] According to this configuration, the projector 100 and the lighting device 200 are capable of wireless communication, the gradation data set by the projector 100 is transmitted to the lighting device 200, and the light-emitting section 250 of the lighting device 200 emits light based on the gradation data, so that the lighting device 200 can be controlled without using a dedicated device such as an MPU. Therefore, the configuration of the lighting control system 1000 can be simplified compared to when a dedicated device such as an MPU is used.

[0059] In addition, it is possible to link the projection image 310 projected by the projector 100 with the color of the lighting device 200, thereby enhancing the spatial presentation effect. Furthermore, the lighting device 200 can illuminate not only the projection image 310 but also the surrounding walls, thereby expanding the video experience. Furthermore, because the color of the projection image 310 is determined from the video data input to the projector 100, it is possible to support any video source, such as streaming video or terrestrial digital broadcasting. Conventional MPUs do not acquire information about the projector 100, and therefore were unable to adjust the gradation values ​​of the projector 100 according to the color conversion settings of the projector 100.

[0060] Furthermore, in the lighting control system 1000 of the first embodiment, it is preferable that the first storage unit 120 stores setting information, and the first image processing unit 160 sets the gradation data based on the video data, image area information, and setting information. With this configuration, the gradation data is set including the setting information in addition to the video data and image area information, so that, for example, the color displayed by the projector 100 and the color emitted by the lighting device 200 can be matched.

[0061] Furthermore, in the lighting control system 1000 of the first embodiment, the setting information is preferably information relating to a mode setting provided in the projector 100. With this configuration, since the setting information is information relating to a mode setting, it is possible to express the color, brightness, etc. of the lighting device 200 in accordance with, for example, theater mode, sports mode, or live mode.

[0062] Furthermore, in the lighting control system 1000 of the first embodiment, it is preferable that the first control unit 110 sets the update frequency of the gradation data based on the setting information. With this configuration, since the update frequency of the gradation data is set based on the setting information, it is possible to increase or decrease the update frequency of the gradation data in accordance with, for example, the video frame rate. This allows for a spatial effect to be achieved.

[0063] Furthermore, in the lighting control system 1000 of the first embodiment, it is preferable that the projector 100 includes a first display unit 170 and receives a request to update the image area information, the first display unit 170 displays a selection screen for selecting the lighting device 200, the projector 100 acquires identification information of the lighting device 200 selected by the user, the first display unit 170 displays an image area information update screen, the projector 100 acquires the image area information selected by the user, and updates the image area information based on the identification information of the lighting device 200 selected by the user and the image area information selected by the user. With this configuration, the image area for obtaining gradation data is set using the projector 100, so the user can adjust the color of the lighting device 200 by simply operating the projector 100 without using any other device.

[0064] Next, the electrical configuration of the lighting control system 1000A of the second embodiment will be described with reference to FIG.

[0065] Lighting control system 1000A of the second embodiment differs from lighting control system 1000 of the first embodiment in that it includes smartphone 400 as an information processing device. Therefore, in the second embodiment, only the parts that differ from the first embodiment will be described in detail, and descriptions of other overlapping parts will be omitted as appropriate.

[0066] 8, a lighting control system 1000A of the second embodiment includes a projector 100, a lighting device 200, and a smartphone 400 as an information processing device. The smartphone 400 is connected to the projector 100 wirelessly.

[0067] As in the first embodiment, the projector 100 has a first control unit 110, a first memory unit 120, a first communication unit 130, a projection unit 140, a video data acquisition unit 150, a first image processing unit 160, and a first display unit 170.

[0068] The lighting device 200 includes a second control unit 210, a second storage unit 220, a second communication unit 230, a second image processing unit 240, and a light emitting unit 250, similar to the first embodiment.

[0069] The smartphone 400 includes a third control unit 410, a third storage unit 420, a third communication unit 430, and a second display unit 440.

[0070] The third control unit 410 is configured to include one or more processors, and operates in accordance with a control program stored in the third storage unit 420 to perform overall control of the operation of the smartphone 400.

[0071] The third storage unit 420 is configured with memories such as RAM (Random Access Memory) and ROM (Read Only Memory). The RAM is used for temporarily storing various data and the like, and the ROM stores control programs and control data for controlling the operation of the smartphone 400. The third storage unit 420 also stores image area information indicating which part of the image area of ​​the entire projected image 310 the image area corresponds to.

[0072] The third communication unit 430 transmits and receives signals to and from the first communication unit 130 of the projector 100.

[0073] Second display unit 440 includes a display panel such as an LCD (liquid crystal display), and displays a selection screen for selecting lighting device 200, an update screen for image region information, and the like.

[0074] Next, a control method of the lighting control system 1000A of the second embodiment, for example, a control method using a UI (User Interface) screen, will be described with reference to Fig. 9 and Fig. 10A to Fig. 10E. In this embodiment, a setting method using the second display unit 440 provided in the smartphone 400 will be described. Note that the projector 100 and the smartphone 400 are paired.

[0075] 9, in step S31, a request to update image area information is accepted. Specifically, for example, the user touches second display unit 440 of smartphone 400.

[0076] In step S32, the image area information and the identification information are acquired from the projector 100. Specifically, when the user touches the second display unit 440, the third control unit 410 of the smartphone 400 sends a signal to the first communication unit 130 of the projector 100 to instruct the third communication unit 430 to acquire the image area information and the identification information stored in the first storage unit 120 of the projector 100. As a result, the third control unit 410 acquires the image area information and the identification information from the projector 100.

[0077] In step S33, a selection screen is displayed. Specifically, third control unit 410 of smartphone 400 causes second display unit 440 to display a menu screen (see FIG. 10A). The user selects "Image Area" from the menu.

[0078] In step S34, the identification information requested by the user is acquired. Specifically, when the image area is selected, the third control unit 410 of the smartphone 400 causes the second display unit 440 to display a list of lighting devices from which the lighting device 200 is to be selected (see FIG. 10B). For example, the first lighting device 200A and the second lighting device 200B are displayed on the second display unit 440. The user selects, for example, the first lighting device 200A from the list of lighting devices. The third control unit 410 acquires the identification information of the first lighting device 200A.

[0079] In step S35, an update screen for the image area information is displayed. Specifically, the third control unit 410 of the smartphone 400 causes the second display unit 440 to display the update screen for the image area information acquired from the projector 100 in step S32 (see FIG. 10C). The user presses the "OK" button displayed under "Please select an image area." As a result, an image 441 reflecting the information on the aspect ratio of the projected image 310 is displayed on the second display unit 440 (see FIG. 10D).

[0080] In step S36, information about an image area selected by the user is acquired. Specifically, the user touches part 442 of the color that the user wants first illumination device 200A to emit light from in displayed image 441 (see FIG. 10E). Third control unit 410 acquires the information about the image area selected by the user.

[0081] In step S37, the image area information is stored. Specifically, the first control unit 110 of the projector 100 stores, in the first storage unit 120, the image area information updated based on the identification information of the first illumination device 200A selected by the user and the image area information selected by the user.

[0082] Thereafter, by performing the same processes as in steps S12 to S16 described above, first illumination device 200A emits light corresponding to the color of the set image area, as shown in Fig. 5B. Note that when second illumination device 200B is made to emit light in the same color as the image area on the right side of projected image 310 (see Fig. 1), projector 100 and second illumination device 200B are set in the same manner as the above method.

[0083] In this way, the image area information for obtaining gradation data is set using smartphone 400, so the user can adjust the color of lighting device 200 by simply operating smartphone 400 without using any other device.
