[Lighting system operation]
Next, the operation of lighting system 100 according to the present embodiment will be described with reference to FIGS. 5 and 6. FIG. FIG. 5 is a flowchart showing an example of a method for lighting projector 10 and lighting fixture 30 of lighting system 100 according to the present embodiment. FIG. 6 is a flowchart showing an example of a method for changing settings of projector 10 and lighting fixture 30 of lighting system 100 according to the present embodiment.

First, a method for lighting the projector 10 and the lighting fixture 30 of the lighting system 100 will be described.

As shown in FIG. 5, first, the operation reception unit 51 of the operation device 50 receives a selection operation by the user of words expressing the impression of the space in which the image is projected (S11). Words representing the impression of the space in which the image is projected are displayed on the operation reception unit 51, and the user selects the displayed words. For example, the words "refreshing" and "relaxing" are displayed on the operation receiving unit 51, and the user selects "refreshing". Further, the operation reception unit 51 receives lighting operations of the projector 10 and the lighting device 30 .

Next, the control unit 53 of the operation device 50 causes the communication unit 52 to transmit a control signal including a signal indicating words to the repeater 70 based on the operation accepted by the operation accepting unit 51 (S12). . A control signal including a signal indicating the transmitted word is received by the communication unit 71 of the repeater 70 (S13). The control unit 72 of the repeater 70 causes the storage unit 73 to store the control signal received by the communication unit 71 .

The control unit 72 of the repeater 70 causes the communication unit 71 to transmit the control signal including the signal indicating the word received in step S13 to the projector 10 and the lighting device 30 (S14). The communication unit 12 of the projector 10 and the communication unit 33 of the lighting fixture 30 receive the control signal including the signal indicating the words transmitted in step S14 (S15 and S16).

The control unit 13 of the projector 10 turns on the light source unit 11a of the projection unit 11, and causes the projection unit 11 to project an image under projection conditions based on the signal indicating the words (S17). For example, the control unit 13 refers to the image projection conditions associated with the signal indicating words as shown in FIG. The projection unit 11 is caused to project an image.

In step S17, the type of content in the image to be projected may be set to one in advance, or may be set by the communication unit 12 of the projector 10 receiving a signal regarding the type of content. Also, the type of content in the video may be associated with a signal indicating words.

In addition, the control unit 34 of the lighting device 30 causes the lighting circuit 32 to light the light source unit 31 and controls the lighting circuit 32 so that the light source unit 31 is illuminated under the irradiation condition based on the signal indicating the word. The installed space is irradiated with illumination light (S18). For example, the control unit 34 refers to the irradiation conditions associated with the signal indicating words as shown in FIG. Project illumination light.

Next, a method for changing the settings of the projector 10 and lighting fixture 30 of the lighting system 100 will be described.

In FIG. 6, through the processing according to the flow shown in FIG. flow is shown. For example, the projection unit 11 of the projector 10 projects the image under the projection condition associated with the signal indicating "clear". Also, the light source unit 31 of the lighting fixture 30 emits illumination light under the irradiation condition associated with the signal indicating "refreshing".

First, the operation receiving unit 51 of the operation device 50 receives a selection operation by the user of words expressing the impression of the space in which the image is projected (S33). In the following steps, a case will be described in which, in step S33, a word different from the word already selected in step S11 of FIG. 5 is selected. For example, the words "refreshing" and "relaxing" are displayed on the operation receiving unit 51, and the user selects "relaxing", which is a different word from "refreshing" corresponding to the projection condition at the time of selection. do.

Next, the control unit 53 of the operation device 50 causes the communication unit 52 to transmit a signal indicating words to the repeater 70 based on the operation accepted by the operation accepting unit 51 (S34). A signal indicating the transmitted word is received by the communication unit 71 of the repeater 70 (S35). The control unit 72 of the repeater 70 causes the storage unit 73 to store the signal indicating the words received by the communication unit 71 .

The control unit 72 of the repeater 70 causes the communication unit 71 to transmit the signal indicating the word received in step S35 to the projector 10 and the lighting device 30 (S36). The communication unit 12 of the projector 10 and the communication unit 33 of the lighting fixture 30 receive the control signal including the signal indicating the words transmitted in step S36 (S37 and S38).

The control unit 13 of the projector 10 changes at least two of the projection conditions of the image projected by the projection unit 11 based on the signal indicating the words (S39). For example, the control unit 13 refers to the video projection conditions associated with the signal indicating words as shown in FIG. changes at least two of the projection conditions of the image projected by . Specifically, the control unit 13 sets the brightness, contrast ratio, focus, aspect ratio, playback speed, chromaticity, and projection angle of the image as projection conditions without changing the type of content of the projected image. and projection magnification. As a result, the manner in which the video is projected changes without changing the type of content in the video, so the impression of the space in which the video is projected can be changed. The control unit 13 may change three or more of the image brightness, contrast ratio, focus, aspect ratio, playback speed, chromaticity, projection angle, and projection magnification as projection conditions, or change four or more. You may By increasing the number of projection conditions to be changed, it becomes easier to change the impression of the space where the image is projected.

Further, among the projection conditions described above, at least one of the focus, aspect ratio, and playback speed of the image may be included in the changed projection conditions. As a result, since the projection conditions under which the impression of the image tends to change are changed, it becomes easier to change the impression of the space where the image is projected without changing the type of content in the image.

In changing the projection conditions in step S<b>39 , the control unit 13 adjusts the content data stored in the storage unit 14 by image processing, and causes the projection unit 11 to project. For example, the control unit 13 performs image processing on the content data stored in the storage unit 14 by calculation, and modulates the light from the light source unit 11a by the light modulation unit 11c according to the image processed. Further, for example, the control unit 13 controls the light source unit 11a or the projection unit 11d to perform image processing on the content data and causes the projection unit 11 to project an image.

Further, the control unit 34 of the lighting fixture 30 changes the irradiation conditions of the illumination light emitted by the light source unit 31 based on the signal indicating the word by controlling the lighting circuit 32 (S40). For example, the control unit 34 refers to the irradiation conditions associated with the signal indicating words as shown in FIG. Change the irradiation conditions of the illumination light that is present.

In this way, signals indicative of speech are transmitted from repeater 70 to projector 10 and lighting fixture 30, and both projector 10 and lighting fixture 30 change projection conditions or illumination conditions based on the signal indicative of speech. . Thereby, in the lighting system 100, the projector 10 and the lighting fixture 30 operate in cooperation.

Note that the lighting device 30 does not need to operate in cooperation with the projector 10 , and may emit illumination light according to irradiation conditions individually set by the operation device 50 .

FIG. 7 is a diagram showing an example of an image projected by projection unit 11 of projector 10 according to the present embodiment. FIG. 7 shows images projected before and after the projection condition is changed in step S39. As shown in FIG. 7, in step S39, the image to be projected is changed from the image shown in FIG. The image is changed to a projection condition image based on the signal indicating “relaxation”. At this time, for example, the control unit 13 changes the projection condition of the image projected by the projection unit 11 by referring to the projection condition of the image associated with the signal indicating the word shown in FIG. In this way, the user changes the image projection conditions as shown in FIG. 7 simply by selecting words that express the impression of the space in which the image is projected. Furthermore, as projection conditions, at least two of image brightness, contrast ratio, focus, aspect ratio, playback speed, chromaticity, projection angle, and projection magnification are changed. Therefore, the mode in which the video is projected changes without changing the type of content in the video, so the atmosphere of the space can be easily changed.

Also, in the second step, at least one of focus, aspect ratio and playback speed of the video may be changed.

As a result, since the projection conditions under which the impression of the image tends to change are changed, it becomes easier to change the impression of the space where the image is projected without changing the type of content in the image.

The projector 10 also includes a projection unit 11 that projects an image, and a communication unit 12 that receives a signal indicating a word designated by the user that expresses the impression of the space in which the image is projected. Further, the projector 10 controls to change at least two of the brightness, contrast ratio, focus, aspect ratio, playback speed, chromaticity, projection angle and projection magnification of the image based on the signal indicating words. A part 13 is provided.

As a result, the projector 10 changes the image projection conditions by receiving the signal indicating the words. In other words, the user can change the image projection conditions simply by selecting words that express the impression of the space in which the image is projected. Furthermore, as projection conditions, at least two of image brightness, contrast ratio, focus, aspect ratio, playback speed, chromaticity, projection angle, and projection magnification are changed. Therefore, even if the type of content in the video is not changed, the atmosphere of the space can be changed. Therefore, the projector 10 that can easily produce a space in which an image is projected is realized.

The projector 10 further includes a storage unit 14 that stores content data used for projecting images. The control unit 13 may adjust the brightness, contrast ratio, focus, aspect ratio, playback speed, chromaticity, projection angle, and projection magnification of the video by image processing the content data.

As a result, one piece of content data can be used for images under a plurality of projection conditions, so the number of pieces of content data used by the projector 10 can be reduced.

Also, the control unit 13 may change at least one of focus, aspect ratio, and playback speed.

As a result, since the projection conditions under which the impression of the image tends to change are changed, it becomes easier to change the impression of the space where the image is projected without changing the type of content in the image.

Also, the contrast ratio of the image may be 100:1 or less.

As a result, the difference in brightness on the image projection surface is reduced, and a space with a natural impression can be produced.

Also, the range of change in video playback speed may be 0.1 times or more and 3.0 times or less.

As a result, it is possible to produce a space with a natural impression without any sense of incongruity in the motion of the video.

Also, the video may be a monochrome video.

As a result, the image is expressed in monochrome, so a space with a natural impression can be produced.

The lighting system 100 also includes a projector 10 and at least one lighting device 30 that does not have a video projection function, and the projector 10 and the lighting device 30 operate in cooperation.

As a result, the projector 10 and the lighting fixture 30 are controlled at the same time, thereby realizing the lighting system 100 that can easily produce a space with a sense of unity.

Also, the number of lighting fixtures 30 may be ten or more.

As a result, the lighting system 100 that can easily create a space even in a large space with ten or more lighting fixtures 30 is realized.
