  Hereinafter, embodiments of the present invention will be described based on examples.

  FIG. 1 is a schematic diagram of a projection system according to the present embodiment. As shown in FIG. 1, the projection system 1 is provided for the bathroom R. The projection system 1 according to the present embodiment projects a video on the wall surface W or the bathtub B in the bathroom R, thereby creating a suitable atmosphere for relaxing in the bathroom R, thereby creating a comfortable bathing environment.

  FIG. 2 shows the configuration of the projection system 1. As shown in FIG. 2, the projection system 1 includes a control panel device (reading device) 10, a first projector (first projection device) 20, a second projector (second projection device) 30, and a speaker device. (Audio output device) 40, control device 50, and content server (recording device) 60 are included. The control device 50 is a device that controls the devices 10 to 40 to control the environment in the bathroom, and can communicate data with a content server 60 that manages various content data via the Internet N or the like. Yes. Hereinafter, each device of the system will be described.

  The control panel device 10 is a device for receiving an operation from a user such as a bather, and includes various operation switches 11 and a barcode reader 12.

  Next, the first projector 20 will be described. The first projector 20 is for projecting an image on the wall surface W in the bathroom R. FIG. 3 is a diagram illustrating a cross-sectional configuration of the first projector 20. As shown in FIG. 3, the first projector 20 includes an optical engine 21, a projection lens 22, a first mirror 23, and a second mirror 24.

  FIG. 4 shows a schematic configuration of the optical engine 21. As shown in FIG. 4, the optical engine 21 includes red light (R light), green light (G light), and blue light (B light) LEDs 210R, 210G, and 210B, collimator lenses 220R, 220G, and 220B, Spatial light modulators 230R, 230G, and 230B and a cross dichroic prism 240 are included.

  The LED 210R is a solid light source that supplies R light. The R light from the LED 210R is collimated by the collimator lens 220R and then enters the spatial light modulator 230R. The spatial light modulator 230R is a transmissive liquid crystal display device that modulates R light according to an image signal. The R light modulated by the spatial light modulator 230R enters the cross dichroic prism 240, which is a color synthesis optical system.

  The LED 210G is a solid light source that supplies G light. The G light from the LED 210G is collimated by the collimator lens 220G and then enters the spatial light modulator 230G. The spatial light modulator 230G is a transmissive liquid crystal display device that modulates G light according to an image signal. The G light modulated by the spatial light modulator 230G enters the cross dichroic prism 240.

  The LED 210B is a solid light source that supplies B light. The B light from the LED 210B is collimated by the collimator lens 220B and then enters the spatial light modulator 230B. The spatial light modulator 230B is a transmissive liquid crystal display device that modulates B light in accordance with an image signal. The B light modulated by the spatial light modulator 230B enters the cross dichroic prism 240.

  On the cross dichroic prism 240, two dichroic films 250 and 260 are formed so as to be substantially orthogonal to each other. The first dichroic film 250 reflects R light and transmits G light and B light. On the other hand, the second dichroic film 260 reflects B light and transmits R light and G light. As a result, the cross dichroic prism 240 combines the R light, G light, and B light incident from different sides and emits the light toward the projection lens 22. The light synthesized by the cross dichroic prism 240 is projected by the projection lens 22.

  The optical engine 21 is not limited to the above-described configuration. For example, a solid light source other than an LED may be used, and light from a lamp light source such as a high-pressure mercury lamp is uniformly supplied by a rod integrator or a fly-eye lens. In this case, uniform parallel light may be incident on the light modulation device. Also, the spatial light modulator is not limited to a transmissive liquid crystal display device, but a reflective liquid crystal display device, DMD (Digital Micromirror Device), GLV (Grating Light Value), or the like may be used.

  Returning to the description of FIG. 3, the first mirror 23 is provided at a position facing the projection lens 22 and the second mirror 24. The first mirror 23 bends the light from the projection lens 22 by reflection and advances the light toward the second mirror 24.

  The second mirror 24 is provided at a position facing the first mirror 23, on the inner side of the casing surrounding the first projector 20 in a box shape, on the surface opposite to the wall surface W. The reflection surface of the second mirror 24 has a curved surface shape that is convex toward the wall surface W, and reflects light from the first mirror 23 to broaden the light mainly in the horizontal direction. . In this way, the distance from the projection lens 22 to the projection surface can be shortened by widening the angle of the light not only by the projection lens 22 but also by the second mirror 24, and compared to the case of widening the angle only by the projection lens 22. Thus, the projection lens 22 can be reduced in size and weight.

  The light reflected by the second mirror 24 travels in the direction along the wall surface W. That is, the light laid on the wall surface W travels. Thereby, the light reflected by the second mirror 24 passes through the transparent member 25 such as glass provided on the emission side of the first projector 20 and irradiates the wall surface W.

  Thus, by sequentially reflecting the light emitted from the optical engine 21 by the first mirror 23 and the second mirror 24, the first projector 20 causes the image light modulated by the spatial light modulator 230 to be applied to the wall surface W in the bathroom. Incident light is projected onto the wall surface W. In addition, since the 1st projector 20 is installed in the wall surface W circumference | surroundings of the bathroom and advances projection light in the direction along the wall surface W, for example, compared with the case where it projects from the facing surface of the wall surface W, image light is in the bathroom. The distance passing through is shortened. Thereby, the fluctuation | variation which arises in the image projected on the wall surface W by the steam which comes out of the hot water of the bathtub B is reduced.

  Moreover, the 2nd projector 30 is for projecting an image on the bathtub B in a bathroom, and is installed so that image light may be projected toward the bathtub B. That is, the second projector 30 projects an image on the bathtub B by causing the image light from the projection lens to enter the bathtub B. The second projector 30 includes an optical engine and a projection lens. Since the optical engine and the projection lens have the same configuration as that of the first projector 20, detailed description of the second projector 30 is omitted. To do.

  The speaker device 40 is a device that outputs sound in the bathroom in accordance with control from the control device 50.

  Next, the control device 50 will be described. As shown in FIG. 2, the control device 50 includes a panel control unit 51, a communication control unit 52, a first projector control unit 53, a second projector control unit 54, a speaker control unit 55, and a content data acquisition unit. 56, a content data storage unit 57, and a content reproduction unit 58.

  The panel control unit 51 is a part that controls the control panel device 10. Specifically, an operation input process to the operation switch 11, a process of acquiring read data obtained by reading the barcode by the barcode reader 12, and the like are executed.

  The communication control unit 52 is a part connected to the Internet N, and controls data communication with the content server 60 via the Internet N.

  The first projector control unit 53 is a part that controls projection of an image by the first projector 20. The second projector control unit 54 is a part that controls projection of an image by the second projector 30. The speaker control unit 55 is a part that controls the sound output by the speaker device 40.

  Here, the bath agent container used in the present projection system 1 will be described. FIG. 5 is a view showing an example of a bath salt container. The bathing agent container 100 has a bag-like structure in which a bathing agent is accommodated inside the container, and a bar code 110 is recorded on the outside of the container. The bar code 110 represents a code for identifying the type of bathing agent contained therein in a predetermined code format. That is, an identification code corresponding to the type of bathing agent is embedded in the bathing agent container 100. The bar code 110 of the bath agent container 100 is read by the bar code reader 12 of the control panel device 10 described above when the bath agent is put into the hot water of the bathtub.

  The content data acquisition unit 56 receives barcode reading data from the control panel device 10 and acquires content data corresponding to the type of bath additive based on the reading data. Specifically, the read data is converted into an identification code, and content data corresponding to the identification code is downloaded from the content server 60. Here, the content server 60 stores in advance content data such as a landscape image and sound of a hot spring area assumed by the bathing agent and a forest landscape image and sound in association with the type of bathing agent. Therefore, the content data acquisition unit 56 acquires content data that matches the color and smell of the bathing agent to be put in the bathtub B. The content data acquisition unit 56 stores the downloaded content data in the content data storage unit 57 in association with the identification code so that the same content data need not be downloaded again thereafter.

  The content reproducing unit 58 performs processing for reproducing the content of the content data. The content data acquired from the content server 60 includes video data for wall surface projection, video data for bathtub projection, and audio data. The image data obtained by reproducing the video for wall projection is output to the first projector 20 via the first projector control unit 53. Image data obtained by reproducing the bathtub projection video is output to the second projector 30 via the second projector control unit 54. The reproduced audio data is output to the speaker device 40 via the speaker control unit 55. In this way, video and audio of content corresponding to the type of bathing agent are output in the bathroom.

When this is instructed, the process of FIG. 6 is started.

  When the process of FIG. 6 is started, first, the barcode reader 12 of the control panel device 10 reads the barcode 110 of the bath additive container 100 and outputs the read data of the barcode 110 to the control device 50 (step S10).

  Next, the content data acquisition unit 56 of the control device 50 interprets the read data received from the control panel device 10 and acquires the bathing agent identification code (step S20).

  Next, the content data acquisition unit 56 determines whether or not the content corresponding to the identification code has been downloaded (step S30). If not downloaded (step S30: No), the content data acquisition unit 56 requests content data corresponding to the identification code from the content server 60 via the communication control unit 52 (step S60). Then, the requested content data is downloaded from the content server 60 and stored in the content data storage unit 57 (step S70).

  Next, the content reproduction unit 58 reproduces the acquired content data and controls projection by the projectors 20 and 30 (step S50). Here, the content reproduction unit 58 outputs the image data for the wall surface of the reproduced content video from the first projector control unit 53 to the first projector 20, so that the video for the wall surface is displayed on the wall surface W of the bathroom. Further, the bathtub image data of the reproduced content video is output from the second projector control unit 54 to the second projector 30, whereby the bathtub image is displayed on the bathtub B in the bathroom. In addition, the audio | voice of content is output in the bathroom by outputting the audio | voice data of the reproduced content image | video from the speaker control part 55 to the speaker apparatus 40. FIG.

  On the other hand, when the content corresponding to the identification code has been downloaded in the past (step S30: Yes), since the corresponding content data is already stored in the content data storage unit 57, the content data corresponding to the identification code is stored in the content. It reads out and acquires from the data storage part 57 (step S40). Thereafter, the process proceeds to step S50, and the content reproduction unit 58 reproduces the downloaded content.

  As described above, in the projection system 1 according to the present embodiment, by reading the barcode 110 of the bath salt container 100, the content video image corresponding to the type of bath salt is displayed on the wall surface W and the bathtub B of the bathroom. It is. This makes it possible to create a comfortable atmosphere in the bathroom that matches the color and smell of hot water from the bathing agent. Moreover, since the sound of the content is output in the bathroom, a more suitable atmosphere is obtained. Therefore, the person who takes a bath does not need to consider what kind of content suits the bathing agent by reading the bar code 110 of the bathing agent container 100, and the type of bathing agent, that is, the color of hot water, You can easily create a comfortable bathing environment that matches the smell.
