[0009] Hereinafter, an embodiment will be described with reference to the drawings.

[0010] [1. Projection system configuration] First, the configuration of the projection system 1 will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of the projection system 1. As shown in Fig. 1, the projection system 1 includes a plurality of projectors 100 and a control device 200. In this embodiment, the plurality of projectors 100 are configured with, for example, a projector 100A, a projector 100B, and a projector 100C. That is, in this embodiment, the plurality of projectors 100 are three projectors 100.

[0011] Each of the projector 100A, the projector 100B, and the projector 100C has substantially the same configuration. Therefore, in the following description, when there is no need to distinguish between the projector 100A, the projector 100B, and the projector 100C, each of the projector 100A, the projector 100B, and the projector 100C may be described as the projector 100. The projector 100 is communicably connected to the control device 200 via a network NW. For example, the projector 100 is communicably connected to the control device 200 in accordance with the Ethernet (registered trademark) standard. The network NW is, for example, a LAN (Local Area Network). The projector 100 projects a projection image PB received from the control device 200 onto a projection surface SC. The projection surface SC is, for example, a wall surface WL. The wall WL will be further explained with reference to FIG.

[0012] In this embodiment, a case will be described in which the projection system 1 includes three projectors 100, but is not limited to this. It is sufficient that the projection system 1 includes at least one projector 100. For example, the projection system 1 may be configured with one or two projectors 100 and a control device 200. Also, for example, the projection system 1 may include four or more projectors 100.

[0013] In this embodiment, the network NW is a LAN, but is not limited to this. The network NW may be, for example, a WAN (Wide Area Network). The network NW may be, for example, the Internet.

[0014] The control device 200 is configured, for example, by a personal computer. The control device 200 stores the original image PA, and outputs information indicating the projection image PB to each of the projector 100A, the projector 100B, and the projector 100C. The information indicating the projection image PB is, for example, first information J1 and second information J2. The original image PA, the first information J1, and the second information J2 will be further described with reference to FIG.

[0015] In this embodiment, the control device 200 is configured as a personal computer, but is not limited to this. The control device 200 may be configured as, for example, a smartphone, a tablet terminal, or the like. Moreover, the control device 200 may be configured as a server device. In other words, the projection system 1 may include a server device instead of the control device 200, and the server device may be connected to each of the three projectors 100 so as to be able to communicate with each other via the Internet.

[0016] [2. Projector placement and configuration] Next, the arrangement of the projector 100 will be described with reference to Fig. 2. Fig. 2 is a cross-sectional view showing an example of the arrangement of the projector 100 according to this embodiment. As shown in Fig. 2, the projector 100 is disposed, for example, above a ceiling CL of an aisle AL. A wall surface WL is provided on the side of the aisle AL, and a floor surface FL is provided below the aisle AL. The aisle AL extends in the depth direction of Fig. 2, in other words, in a direction perpendicular to the paper surface. The projector 100 projects image light PL onto the wall surface WL, for example, passing through a hole HL formed in the ceiling CL.

[0017] Each of the projectors 100A, 100B, and 100C is arranged along an aisle AL. A center line PLA indicates the center of the image light PL from the projector 100. The projector 100 is arranged so that the center line PLA is inclined with respect to a wall surface WL. The image light PL from the projector 100 is used, for example, as indirect lighting for the aisle AL. Since the projector 100 displays the projected image PB on the wall surface WL, a beautiful landscape or the like can be displayed as the projected image PB, allowing pedestrians passing through the passage AL to enjoy the projected image PB. In addition, the aesthetic appearance of the passage AL can be improved.

[0018] 2, the projector 100 projects the projection image PB onto a wall surface WL, which is an example of a projection surface SC. The projector 100 displays the projection image PB on the wall surface WL, for example, by projecting image light PL toward the wall surface WL. The projection image PB will be further described with reference to FIGS.

[0019] In this embodiment, a case will be described in which the projector 100 displays the projection image PB on a wall surface WL, for example, but the projector 100 may also display the projection image PB on a floor surface FL, for example.

[0020] Next, the configuration of the projector 100 will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the configuration of the projector 100 according to this embodiment. 3, the projector 100 includes a projection unit 110 and a drive unit 120 that drives the projection unit 110. The projection unit 110 is an optical device that forms an optical image and projects the image onto a projection surface SC. The projection unit 110 includes a light source unit 111, a light modulation device 112, and a projection optical system 113. The drive unit 120 includes a light source drive unit 121 and a light modulation device drive unit 122.

[0021] The light source unit 111 includes a lamp such as a halogen lamp, a xenon lamp, or an extra-high pressure mercury lamp, or a solid-state light source such as an LED (Light Emitting Diode) or a laser light source. The light source unit 111 may also include a reflector and an auxiliary reflector that guide the light emitted by the light source to the light modulation device 112. Furthermore, the light source unit 111 may also include a lens group for improving the optical characteristics of the projected light, a polarizing plate, or a dimming element that reduces the amount of light emitted by the light source on the path leading to the light modulation device 112. The light source driving unit 121 is connected to the internal bus 107 , and turns on and off the light source of the light source unit 111 according to instructions from a first control unit 150 also connected to the internal bus 107 .

[0022] The light modulation device 112 includes, for example, three liquid crystal panels 115 corresponding to the three primary colors of R, G, and B. R indicates red, G indicates green, and B indicates blue. That is, the light modulation device 112 includes a liquid crystal panel 115 corresponding to R light, a liquid crystal panel 115 corresponding to G light, and a liquid crystal panel 115 corresponding to B light. The light emitted by the light source unit 111 is separated into three color lights of RGB, and each color light is incident on a corresponding liquid crystal panel 115. Each of the three liquid crystal panels 115 is a transmissive liquid crystal panel, and generates image light PL by modulating the light passing through it. The image light PL modulated after passing through each liquid crystal panel 115 is combined by a combining optical system such as a cross dichroic prism, and is emitted to the projection optical system 113. Each of the liquid crystal panels 115 may be, for example, a reflective liquid crystal panel or a DMD (Digital Mirror Device), etc.

[0023] The light modulation device 112 is driven by a light modulation device driving section 122. The light modulation device driving section 122 is connected to an image processing section 145. Image data corresponding to each of the primary colors R, G, and B is input to the light modulation device driving unit 122 from the image processing unit 145. The light modulation device driving unit 122 converts the input image data into a data signal suitable for the operation of the liquid crystal panel 115. The light modulation device driving unit 122 applies a voltage to each pixel of each liquid crystal panel 115 based on the converted data signal, and draws an image corresponding to the projection image PB on each liquid crystal panel 115.

[0024] The projection optical system 113 includes lenses, mirrors, etc. that form an image of the incident image light PL on the projection surface SC. The projection optical system 113 may also include a zoom mechanism that enlarges or reduces the image projected onto the projection surface SC, a focus adjustment mechanism that adjusts the focus, etc.

[0025] The projector 100 further includes an operation unit 131, a remote control receiver 133, an input interface 135, a storage unit 137, a first communication interface 141, a frame memory 143, an image processing unit 145, and a first control unit 150. The input interface 135, the storage unit 137, the first communication interface 141, the image processing unit 145, and the first control unit 150 are connected to each other via an internal bus 107 so as to be able to communicate data with each other.

[0026] The operation unit 131 includes various buttons and switches provided on the surface of the housing of the projector 100, generates operation signals corresponding to the operations of these buttons and switches, and outputs the operation signals to the input interface 135. The input interface 135 outputs the operation signals input from the operation unit 131 to the first control unit 150.

[0027] The remote control light receiving unit 133 receives an infrared signal transmitted from the remote control 5, and decodes the received infrared signal to generate an operation signal. The remote control light receiving unit 133 outputs the generated operation signal to the input interface 135. The input interface 135 outputs the operation signal input from the remote control light receiving unit 133 to the first control unit 150.

[0028] The storage unit 137 is, for example, a non-volatile storage device such as a hard disk drive (HDD) or a solid state drive (SSD). The storage unit 137 stores programs executed by the first control unit 150, data processed by the first control unit 150, image data, and the like.

[0029] The first communication interface 141 includes a connector and an interface circuit, and is communicatively connected to the control device 200. In this embodiment, the first communication interface 141 is an interface for communicating with the control device 200 in accordance with, for example, the Ethernet (registered trademark) standard. The first communication interface 141 receives information indicating the projection image PB from the control device 200.

[0030] The first control unit 150 includes a first processor 150A and a first memory 150B. The first memory 150B is a storage device that non-volatilely stores programs and data executed by the first processor 150A. The first memory 150B is configured with a semiconductor storage element such as a magnetic storage device or a flash ROM (Read Only Memory), or other types of non-volatile storage devices. The first memory 150B may also include a RAM (Random Access Memory) that configures a work area for the first processor 150A. The first memory 150B may also include a non-volatile storage device such as an HDD or SSD. The first memory 150B stores data to be processed by the first control unit 150 and the first control program PG1 to be executed by the first processor 150A.

[0031] The first processor 150A may be configured as a single processor, or may be configured such that a plurality of processors function as the first processor 150A. The first processor 150A executes a first control program PG1 to control each unit of the projector 100. For example, the first processor 150A outputs to the image processing unit 145 an instruction to execute image processing corresponding to an operation received by the operation unit 131 or the remote control 5, and parameters used in the image processing. The parameters include, for example, geometric correction parameters for correcting geometric distortion of the projection image PB projected on the projection surface SC. The first processor 150A also controls the light source driving unit 121 to control the turning on and off of the light source unit 111.

[0032] Each of the image processing unit 145 and the first control unit 150 can be configured, for example, by an integrated circuit. The integrated circuit includes an LSI, an application specific integrated circuit (ASIC), and a programmable logic device (PLD). The PLD includes, for example, a field programmable gate array (FPGA). Furthermore, an analog circuit may be included as part of the configuration of the integrated circuit, or a combination of a processor and an integrated circuit may be used. The combination of a processor and an integrated circuit is called a microcontroller (MCU), a system-on-a-chip (SoC), a system LSI, a chipset, or the like.

[0033] The image processing unit 145 expands the image data stored in the first memory 150B or the storage unit 137 into the frame memory 143. The frame memory 143 includes a plurality of banks. Each bank has a storage capacity capable of writing one frame's worth of image data. The frame memory 143 is configured, for example, by a Synchronous Dynamic Random Access Memory (SDRAM).

[0034] In accordance with instructions from the first control unit 150, the image processing unit 145 performs image processing such as resolution conversion processing or resizing processing, distortion aberration correction, shape correction processing, digital zoom processing, and adjustment of the color tone and brightness of the image on the image data expanded in the frame memory 143.

[0035] The first processor 150A of the first control unit 150 executes the first control program PG1 to perform, for example, the following processing. The first processor 150A causes the first communication interface 141 to receive information indicating the projection image PB from the control device 200. Then, the first processor 150A causes the liquid crystal panel 115 to display an image corresponding to the projection image PB via the light modulation device driving unit 122. Furthermore, the first processor 150A causes the projection unit 110 to project image light PL indicating the projection image PB onto the wall surface WL via the driving unit 120. In this manner, the projector 100 displays the projection image PB on the wall surface WL.

[0036] [3. Control device configuration] Next, the configuration of the control device 200 will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of the configuration of the control device 200 according to this embodiment. The control device 200 is configured, for example, by a personal computer. As shown in FIG. 4, the control device 200 includes a second control unit 210, an operation mechanism 220, a display mechanism 230, and a second communication interface 240.

[0037] The second control unit 210 includes a second processor 210A and a second memory 210B. The second memory 210B is a storage device that non-volatilely stores programs and data executed by the second processor 210A. The second memory 210B is configured with a semiconductor storage element such as a magnetic storage device or a flash ROM, or other types of non-volatile storage devices. The second memory 210B may also include a RAM that configures the work area of ​​the second processor 210A. The second memory 210B may also include a non-volatile storage device such as an HDD or SSD. The second memory 210B stores data processed by the second control unit 210 and the second control program PG2 executed by the second processor 210A.

[0038] The second processor 210A may be configured as a single processor, or may be configured with multiple processors functioning as the second processor 210A. The second processor 210A controls each part of the control device 200 by executing a second control program PG2.

[0039] The operation mechanism 220 receives an operation from a user, generates an operation signal corresponding to the operation, and transmits the operation signal to the second control unit 210. The operation mechanism 220 is constituted by, for example, a keyboard, a mouse, a touch panel, and the like. The display mechanism 230 includes an LCD (Liquid Crystal Display) or the like, and displays various images on the LCD in accordance with instructions from the second control unit 210. The display mechanism 230 may be replaced by an interface capable of outputting video, and may display various images on a display such as an LCD connected to the interface. The second communication interface 240 includes a connector and an interface circuit, and is communicatively connected to the projector 100. In this embodiment, the second communication interface 240 is an interface for communicating with the projector 100, for example, in accordance with the Ethernet (registered trademark) standard. The second communication interface 240 transmits information indicating the projection image PB to the projector 100 in accordance with an instruction from the second control unit 210. The second communication interface 240 may include a wireless communication circuit, and may perform wireless communication with the projector 100. For example, the second communication interface 240 may communicate with the projector 100 in accordance with the Wi-Fi (registered trademark) standard.

[0040] 2, the second control unit 210 includes an instruction receiving unit 211, a first processing unit 212, a second processing unit 213, a first synthesis unit 214, a second synthesis unit 215, and an image storage unit 216. Specifically, the second processor 210A of the second control unit 210 executes the second control program PG2 stored in the second memory 210B to function as the instruction receiving unit 211, the first processing unit 212, the second processing unit 213, the first synthesis unit 214, and the second synthesis unit 215. In addition, the second processor 210A of the second control unit 210 executes the second control program PG2 stored in the second memory 210B to cause the second memory 210B to function as the image storage unit 216. The second processor 210A corresponds to an example of a "processor." The second control program PG2 corresponds to an example of a "program."

[0041] The image storage unit 216 prestores a first image P1 and a second image P2. Each of the first image P1 and the second image P2 corresponds to an example of an original image PA. The "original image" is an image used when the second control unit 210 generates the projection image PB. In other words, the projection image PB is generated by performing a read process or the like to read out a partial area of ​​the original image PA. In other words, the original image PA is an image that is the source for generating the projection image PB.

[0042] The first image P1 is an original image PA in which a plurality of images are arranged as one image. The plurality of images is, for example, four images. The four images are, for example, small images P11, P12, P13, and P14. The small images P11 to P14 correspond to an example of "a plurality of images." The first image P1, i.e., the small images P11 to P14, will be further described with reference to FIG. 5. The second image P2 is the original image PA when the original image PA is composed of one image. The second image P2 will be further described with reference to FIG.

[0043] In the present embodiment, a case will be described in which the image storage unit 216 stores the first image P1 and the second image P2 in advance, but is not limited to this. It is sufficient that the image storage unit 216 stores at least one of the first image P1 and the second image P2 in advance.

[0044] The instruction receiving unit 211 receives instructions from a user based on an operation of the operation mechanism 220 by the user. The instruction receiving unit 211 receives, for example, a selection of a projection image PB to be projected by each of the projector 100A, the projector 100B, and the projector 100C. The instruction receiving unit 211 receives, for example, a selection of whether to cause the projector 100 to project an image included in the first image P1 or to cause the projector 100 to project an image included in the second image P2.

[0045] For example, when making the projector 100 project an image included in the first image P1, the instruction receiving unit 211 performs the following process. That is, the instruction receiving unit 211 receives, for example, a selection of which image from among the small images P11 to P14 constituting the first image P1 is to be projected by each of the projector 100A, the projector 100B, and the projector 100C. Furthermore, for example, when the projector 100 projects an image included in the second image P2, the instruction receiving unit 211 performs the following process. That is, the instruction receiving unit 211 receives, for example, a selection of which area of ​​the second image P2 is to be projected by each of the projector 100A, the projector 100B, and the projector 100C.

[0046] Furthermore, the instruction receiving unit 211 receives, for example, a selection of whether to cause the projector 100 to project the first composite image CP1 or the projector 100 to project the second composite image CP2. The first composite image CP1 is generated by the first composition unit 214 compositing two images out of the multiple images arranged in the first image P1, for example, the small images P11 to P14. The first composite image CP1 is generated by the first composition unit 214, for example, overlapping or arranging two images out of the small images P11 to P14. The second composite image CP2 is generated by the second composition unit 215 compositing an image corresponding to the first region ARA in the second image P2 and an image corresponding to a second region ARB different from the first region ARA in the second image P2. The second composite image CP2 is generated by the first composition unit 214, for example, overlapping or arranging the image corresponding to the first region ARA and the image corresponding to the second region ARB.

[0047] When the projector 100 projects the first composite image CP1, the instruction receiving unit 211 receives a selection of two images from the small images P11 to P14. When the projector 100 projects the first composite image CP1, the instruction receiving unit 211 receives an instruction on a method of combining the two images. When the projector 100 projects the second composite image CP2, the instruction receiving unit 211 receives an instruction regarding the first area ARA of the second image P2 and the second area ARB of the second image P2. When the projector 100 projects the second composite image CP2, the instruction receiving unit 211 receives an instruction regarding a method of combining the image of the first area ARA and the image of the second area ARB.

[0048] When the original image PA is a first image P1 in which small images P11 to P14 are arranged as one image, the first processing unit 212 executes a first process to output first information J1 indicating one of the small images P11 to P14 as information indicating the projected image PB. The first process will be further described with reference to FIG.

[0049] When the original image PA is a second image 2 consisting of a single image, the second processing unit 213 executes a second process to output second information J2 indicating an image corresponding to a partial area of ​​the second image 2 as information indicating the projected image PB. The second process will be further described with reference to FIG.

[0050] The first synthesis unit 214 executes the third process when the original image PA is the first image P1 and the instruction receiving unit 211 receives a selection indicating that the projector 100 is to project the first synthesized image CP1. The third process includes a process of superimposing or arranging two images among the small images P11 to P14 to composite the two images and generate a first composite image CP1. The two images are selected from the small images P11 to P14 by the instruction receiving unit 211. The method of compositely combining the two images is instructed by the instruction receiving unit 211. The third process also includes a process of outputting third information J3 indicating the first composite image CP1 as information indicating the projection image PB, instead of the first information J1.

[0051] The second synthesis unit 215 executes the fourth process when the original image PA is the second image P2 and the instruction receiving unit 211 receives a selection indicating that the projector 100 is to project the second synthesized image CP2. The fourth process includes a process of superimposing or arranging an image corresponding to the first area ARA of the second image P2 and an image corresponding to a second area ARB of the second image P2 different from the first area ARA, thereby synthesizing the two images and generating a second composite image CP2. Note that each of the first area ARA and the second area ARB is instructed by the instruction receiving unit 211 for the second image P2. Also, a method of synthesizing the two images is instructed by the instruction receiving unit 211. Also, the fourth process includes a process of outputting fourth information J4 indicating the second composite image CP2 as information indicating the projection image PB, instead of the second information J2.

[0052] In this embodiment, a case will be described in which the second control unit 210 of the control device 200 includes an instruction receiving unit 211, a first processing unit 212, a second processing unit 213, a first synthesis unit 214, a second synthesis unit 215, and an image storage unit 216, but is not limited thereto. For example, the first control unit 150 of each of the projectors 100, that is, the projector 100A, the projector 100B, and the projector 100C, may include the instruction receiving unit 211, the first processing unit 212, the second processing unit 213, the first synthesis unit 214, the second synthesis unit 215, and the image storage unit 216. In this case, the projection system 1 does not need to include the control device 200. In this case, the first processor 150A corresponds to an example of a "processor".

[0053] [4. Example of the first image] Next, an example of the first image P1 will be described with reference to Fig. 5. Fig. 5 is an image diagram showing an example of the first image P1. As shown in Fig. 5, in the first image P1, small images P11, P12, P13, and P14 are arranged as one image. The small images P11, P12, P13, and P14 are arranged in two rows and two columns. The small images P11 and P12 are arranged in the left-right direction, and the small images P13 and P14 are arranged in the left-right direction. In addition, the small images P11 and P13 are arranged in the up-down direction, and the small images P12 and P14 are arranged in the up-down direction.

[0054] The small images P11 to P14 are all the same size, and each of the images P1 to P14 is a horizontally long rectangular image. Each of the small images P11 to P14 is an image of an area surrounded by a boundary line BL. In other words, the boundary line BL is composed of the outer periphery of the first image P1, a line segment extending in the left-right direction, and a line segment extending in the up-down direction. The line segments extending in the left-right direction are disposed between the small images P11 and P13, and between the small images P12 and P14. The line segments extending in the up-down direction are disposed between the small images P11 and P12, and between the small images P13 and P14.

[0055] When the original image PA is the first image P1, the first processing unit 212 executes a first process of outputting first information J1 indicating one of the small images P11 to P14 as information indicating the projection image PB. The first processing unit 212 outputs, for example, to the projector 100A, the first information J1 indicating the small image P11 as information indicating the projection image PB. Also, the first processing unit 212 outputs, for example, to the projector 100B, the first information J1 indicating the small image P12 as information indicating the projection image PB. Also, the first processing unit 212 outputs, for example, to the projector 100C, the first information J1 indicating the small image P13 as information indicating the projection image PB.

[0056] The first information J1 is, for example, image information of one area AR1N (where N is an integer between 1 and 4) surrounded by a boundary line BL in the first image P1. The area AR1N is a rectangular area. In this case, the first processing unit 212 outputs, for example, the image information of the area AR11 to the projector 100A as information indicating the projection image PB. Also, the first processing unit 212 outputs, for example, the image information of the area AR12 to the projector 100B as information indicating the projection image PB. Also, the first processing unit 212 outputs, for example, the image information of the area AR13 to the projector 100C as information indicating the projection image PB.

[0057] Furthermore, the first information J1 may be, for example, information indicating the first image P1 and information indicating an area AR1N (where N is an integer from 1 to 4) corresponding to one image P1N (where N is an integer from 1 to 4) in the first image P1. In this case, the first processing unit 212 outputs, for example, to the projector 100A, information indicating the first image P1 and information indicating the area AR11 as information indicating the projection image PB. Also, the first processing unit 212 outputs, for example, to the projector 100B, information indicating the first image P1 and information indicating the area AR12 as information indicating the projection image PB. Also, the first processing unit 212 outputs, for example, to the projector 100C, information indicating the first image P1 and information indicating the area AR13 as information indicating the projection image PB. The area AR1N may or may not include the boundary line BL.

[0058] In this embodiment, the case where the region AR1N is a rectangular region will be described, but is not limited thereto. The region AR1N may be, for example, a circular region or an elliptical region. The region AR1N may also be, for example, a star-shaped region. In addition, in the present embodiment, the first image P1 is four images, that is, the small images P11 to P14 are arranged as one image, but the present invention is not limited to this. The first image P1 may be a plurality of images arranged as one image. The plurality of images may be two images, three images, or five or more images. The greater the number of images constituting the first image P1, the greater the degree of freedom in selecting the projection image PB. In addition, in the present embodiment, the first image P1 is four images, that is, the small images P11 to P14 are arranged vertically and horizontally as one image, but the present invention is not limited to this. It is sufficient that the first image P1 is a single image in which a plurality of images are arranged. For example, the first image P1 may be a single image in which a plurality of images are arranged horizontally. Also, for example, the first image P1 may be a single image in which a plurality of images are arranged vertically.

[0059] [5. Example of the second image] Next, an example of the second image P2 will be described with reference to Fig. 6. Fig. 6 is an image diagram showing an example of the second image P2. As shown in FIG. 6, the second image P2 is composed of one image. A plurality of regions AR2K (where K is an integer between 1 and 3) are set in the second image P2 by the instruction receiving unit 211. The region AR21 is disposed, for example, in the upper left of the second image P2. The regions AR22 and AR23 are disposed, for example, in the lower right of the region AR21. The region AR23 is disposed, for example, in the upper right of the region AR22. Each of the regions AR21 to AR23 corresponds to an example of "a portion of the region" of the second image P2. The regions AR21 to AR23 have the same size, and each of the regions AR21 to AR23 is a circular region.

[0060] When the original image PA is the second image P2, the second processing unit 213 executes a second process of outputting second information J2 indicating an image corresponding to one of the areas AR21 to AR23 as information indicating the projection image PB. The second processing unit 213 outputs, for example, to the projector 100A, second information J2 indicating an area image P21 corresponding to the area AR21 as information indicating the projection image PB. The area image P21 corresponds to an example of an image corresponding to the area AR21. Furthermore, the second processing unit 213 outputs, for example, to the projector 100B, second information J2 indicating an area image P22 corresponding to the area AR22 as information indicating the projection image PB. The area image P22 corresponds to an example of an image corresponding to the area AR22. Furthermore, the second processing unit 213 outputs, for example, to the projector 100C, second information J2 indicating an area image P23 corresponding to the area AR23 as information indicating the projection image PB. The area image P23 corresponds to an example of an image corresponding to the area AR23.

[0061] The second information J2 is, for example, image information corresponding to a partial area AR2K (where K is an integer from 1 to 3) of the second image P2. In this case, the second processing unit 213 outputs image information corresponding to the region image P21, i.e., image information indicating the region image P21, to the projector 100A, as information indicating the projection image PB. Also, the second processing unit 213 outputs image information corresponding to the region image P22, i.e., image information indicating the region image P22, to the projector 100B, as information indicating the projection image PB. Also, the second processing unit 213 outputs image information corresponding to the region image P23, i.e., image information indicating the region image P23, to the projector 100C, as information indicating the projection image PB.

[0062] The second information J2 may be, for example, information indicating the second image P2 and information indicating an area AR2K (where K is an integer between 1 and 3) in the second image P2. As shown in Fig. 6, for example, a U axis and a V axis are set as coordinate axes. In this case, the information indicating the area AR2K is information indicating the (U, V) coordinates of the center position of the area AR2K and information indicating the radius (or diameter) of the area AR2K. In this case, the second processing unit 213 outputs, for example, to the projector 100A, information indicating the second image P2 and information indicating the area AR21 in the second image P2 as information indicating the projection image PB. Also, the second processing unit 213 outputs, for example, to the projector 100B, information indicating the second image P2 and information indicating the area AR22 in the second image P2 as information indicating the projection image PB. Also, the second processing unit 213 outputs, for example, to the projector 100C, information indicating the second image P2 and information indicating the area AR23 in the second image P2 as information indicating the projection image PB.

[0063] In this embodiment, the case where the area AR2K is a circular area will be described, but the present invention is not limited to this. The area AR2K may be, for example, a rectangular area, an elliptical area, or a star-shaped area. In addition, in the present embodiment, the regions AR21 to AR23 have the same shape, but the present invention is not limited to this. For example, the regions AR21 to AR23 may have different shapes. In addition, in the present embodiment, the regions AR21 to AR23 are the same in size, but the present invention is not limited to this. For example, the regions AR21 to AR23 may be different in size. By not placing restrictions on the position, shape, size, etc. for each of the areas AR2K, the degree of freedom in selecting the projection image PB can be increased.

[0064] [6. Processing of control unit] Next, an example of the process of the second control unit 210 will be described with reference to Fig. 7. Fig. 7 is a flowchart showing an example of the process of the second control unit 210. 7 will be described in the case where the second control unit 210 outputs the first information J1 or the second information J2 to the projector 100. Also, in FIG 7, a case will be described where the image storage unit 216 of the second control unit 210 stores in advance the first image P1 or the second image P2 as the original image PA.

[0065] As shown in FIG. 7, in step S101, the second control unit 210 determines whether or not the original image PA is the first image P1. When the second control unit 210 determines that the original image PA is the first image P1 (step S101; YES), the process proceeds to step S113. When the second control unit 210 determines that the original image PA is not the first image P1 (step S101; NO), the process proceeds to step S103. Then, in step S103, the second control unit 210 determines whether or not the original image PA is the second image P2. If the second control unit 210 determines that the original image PA is not the second image P2 (step S103; NO), the process returns to step S101. If the second control unit 210 determines that the original image PA is the second image P2 (step S103; YES), the process proceeds to step S105.

[0066] Then, in step S105, the instruction receiving unit 211 receives a selection of which image of the region AR of the second image P2 is to be projected by each of the projector 100A, the projector 100B, and the projector 100C. For example, the instruction receiving unit 211 receives a selection of an instruction to have the projector 100A project an image corresponding to the region AR21 of the second image P2. Also, the instruction receiving unit 211 receives a selection of an instruction to have the projector 100B project an image corresponding to the region AR22 of the second image P2. Also, the instruction receiving unit 211 receives a selection of an instruction to have the projector 100C project an image corresponding to the region AR23 of the second image P2. Next, in step S107, the second processing unit 213 reads out a region image P2K corresponding to the region AR2K (where K is an integer between 1 and 3) selected by the instruction receiving unit 211 from the second image P2.

[0067] Next, in step S109, the second processing unit 213 outputs the second information J2 indicating the area image P2K corresponding to the area AR2K to the projector 100 as information indicating the projection image PB. The second processing unit 213 outputs, for example, the second information J2 indicating the area image P21 corresponding to the area AR21 to the projector 100A as information indicating the projection image PB. In addition, the second processing unit 213 outputs, for example, the second information J2 indicating the area image P22 corresponding to the area AR22 to the projector 100B as information indicating the projection image PB. In addition, the second processing unit 213 outputs, for example, the second information J2 indicating the area image P23 corresponding to the area AR23 to the projector 100C as information indicating the projection image PB. Next, in step S111, the second control unit 210 causes the projector 100 to project the projection image PB onto the wall surface WL. The second control unit 210 causes the projector 100A to display, for example, a region image P21 on the liquid crystal panel 115 and project the region image P21 onto the wall surface WL. The second control unit 210 also causes the projector 100B to display, for example, a region image P22 on the liquid crystal panel 115 and project the region image P22 onto the wall surface WL. The second control unit 210 also causes the projector 100C to display, for example, a region image P23 on the liquid crystal panel 115 and project the region image P23 onto the wall surface WL. After that, the process ends. When the projector 100 displays the area image P2K (where K is an integer between 1 and 3) on the liquid crystal panel 115, it displays a black image in the blank area.

[0068] If the answer is YES in step S101, in step S113, the instruction receiving unit 211 receives a selection of which image among the small images P11 to P14 constituting the first image P1 is to be projected by each of the projector 100A, the projector 100B, and the projector 100C. The instruction receiving unit 211 receives, for example, a command to have the projector 100A project the small image P11. The instruction receiving unit 211 also receives, for example, a command to have the projector 100B project the small image P12. The instruction receiving unit 211 also receives, for example, a command to have the projector 100C project the small image P13. Next, in step S115, the first processing unit 212 reads out the small image P1M (where M is an integer from 1 to 3) selected by the instruction receiving unit 211 from the first image P1.

[0069] Next, in step S117, the first processing unit 212 outputs the first information J1 indicating each of the small images P11 to P13 to the projector 100 as information indicating the projection image PB. For example, the first processing unit 212 outputs the first information J1 indicating the small image P11 to the projector 100A as information indicating the projection image PB. In addition, the first processing unit 212 outputs, for example, the first information J1 indicating the small image P12 to the projector 100B as information indicating the projection image PB. In addition, the first processing unit 212 outputs, for example, the first information J1 indicating the small image P13 to the projector 100C as information indicating the projection image PB. Next, in step S119, the second control unit 210 causes the projector 100 to project the projection image PB onto the wall surface WL. The second control unit 210 causes the projector 100A to display, for example, a small image P11 on the liquid crystal panel 115 and project the small image P11 onto the wall surface WL. The second control unit 210 also causes the projector 100B to display, for example, a small image P12 on the liquid crystal panel 115 and project the small image P12 onto the wall surface WL. The second control unit 210 also causes the projector 100C to display, for example, a small image P13 on the liquid crystal panel 115 and project the small image P13 onto the wall surface WL. After that, the process ends. When the projector 100 displays the small image P1M (where M is an integer between 1 and 3) on the liquid crystal panel 115, the projector 100 displays a black image in the marginal area.

[0070] Steps S115 and S117 correspond to an example of a “first process.” Steps S107 and S109 correspond to an example of a “second process.”

[0071] [7. This embodiment and its effects] As described above with reference to Figures 1 to 7, the information output method of this embodiment includes performing a first process to output first information J1 indicating one of the small images P11 to P14 as information indicating the projected image PB when the original image PA is a first image P1 in which small images P11 to P14 are arranged as one image, and performing a second process to output second information J2 indicating images corresponding to each of some areas AR21 to AR23 of the second image P2 as information indicating the projected image PB when the original image PA is a second image P2 consisting of a single image. According to this configuration, the information output method executes a first process to output first information J1 indicating one of the small images P11 to P14 as information indicating the projection image PB when the original image PA is a first image P1 in which the small images P11 to P14 are arranged as one image, and executes a second process to output second information J2 indicating images corresponding to each of the regions AR21 to AR23, which are part of the second image P2, as information indicating the projection image PB when the original image PA is a second image P2 consisting of one image. Therefore, the degree of freedom in selecting the projection image PB can be increased, both when the original image PA is the first image P1 and when the original image PA is the second image P2. Therefore, it is possible to cause the projector 100 to project a variety of images.

[0072] Furthermore, in the information output method of this embodiment, each of the small images P11 to P14 is an image of an area AR11 to AR14 surrounded by a boundary line BL, the first information J1 is image information of one of the areas AR11 to AR14 surrounded by the boundary line BL in the first image P1, and the second information J2 is image information corresponding to a portion of the areas AR21 to AR23 in the second image P2. According to this configuration, the first information J1 is image information of one area AR11 to AR14 surrounded by boundary line BL in the first image P1, and the second information J2 is image information corresponding to a part of the second image P2, that is, areas AR21 to AR23. Therefore, the first information J1 and the second information J2 are image information corresponding to the region, whether the original image PA is the first image P1 or the original image PA is the second image P2. Therefore, the projector 100 can easily project the projection image PB based on the first information J1 and the second information J2. As a result, the processing of the projector 100 can be simplified.

[0073] Furthermore, in the information output method of this embodiment, the first information J1 is information indicating the first image P1 and information indicating each of areas AR11 to AR14 in the first image P1, and the second information J2 is information indicating the second image P2 and information indicating each of areas AR21 to AR23 in the second image P2. According to this configuration, the first information J1 is information indicating the first image P1 and information indicating each of areas AR11 to AR14 in the first image P1, and the second information J2 is information indicating the second image P2 and information indicating each of areas AR21 to AR23 in the second image P2. Therefore, whether the original image PA is the first image P1 or the original image PA is the second image P2, the projector 100 can easily generate the projection image PB from each of the first information J1 and the second information J2. Therefore, the projector 100 can easily project the projection image PB based on the first information J1 and the second information J2. As a result, the processing of the projector 100 can be simplified.

[0074] Furthermore, the information output method of this embodiment includes generating a first composite image CP1 by superimposing or arranging two of the small images P11 to P14, and outputting, in a first process, third information J3 indicating the first composite image CP1 as information indicating the projected image PB instead of the first information J1. According to this configuration, a first composite image CP1 is generated by superimposing or arranging two of the small images P11 to P14, and third information J3 indicating the first composite image CP1 is output as information indicating the projection image PB in place of the first information J1. Therefore, the projector 100 can project the first composite image CP1 generated by overlapping or arranging two images among the small images P11 to P14 as the projection image PB. Therefore, it is possible to cause the projector 100 to project a variety of images.

[0075] Furthermore, the information output method of this embodiment includes generating a second composite image CP2 by superimposing or arranging an image corresponding to a first area ARA in the second image P2 and an image corresponding to a second area ARB in the second image P2 that is different from the first area ARA, and outputting, in a second process, fourth information J4 indicating the second composite image CP2 as information indicating the projected image PB instead of the second information J2. According to this configuration, a second composite image CP2 is generated by superimposing or arranging an image corresponding to a first area ARA in the second image P2 and an image corresponding to a second area ARB in the second image P2 that is different from the first area ARA, and fourth information J4 indicating the second composite image CP2 is output as information indicating the projected image PB in place of the second information J2. Therefore, the projector 100 can project, as the projection image PB, the second composite image CP2 generated by overlapping or arranging an image corresponding to the first area ARA in the second image P2 and an image corresponding to the second area ARB different from the first area ARA in the second image P2. Therefore, it is possible to cause the projector 100 to project a variety of images.

[0076] Furthermore, in the information output method of this embodiment, the first process includes selecting one of the small images P11 to P14 based on a user operation, and the second process includes selecting a partial area of ​​the second image P2 based on a user operation. According to this configuration, the information output method selects one of the small images P11 to P14 based on an operation from the user, and selects a partial area of ​​the second image P2 based on an operation from the user. Therefore, the user can select an image desired by the user from among the small images P11 to P14 as the projection image PB, and can select an image of an area desired by the user in the second image P2 as the projection image PB, thereby improving user convenience.

[0077] Furthermore, the information output method according to the present embodiment includes determining the shape of the projection image PB according to the projection surface SC onto which the projector 100 projects the projection image PB. According to this configuration, the projector 100 determines the shape of the projection image PB according to the projection surface SC onto which the projection image PB is projected. Therefore, the shape of the projection image PB can be determined to be an appropriate shape. This allows the projector 100 to project a variety of images.

[0078] In addition, the second control program PG2 in this embodiment causes the second processor 210A of the control device 200 to execute a first process of outputting first information J1 indicating one of the small images P11 to P14 as information indicating the projected image PB when the original image PA is the first image P1 in which the small images P11 to P14 are arranged as one image, and a second process of outputting second information J2 indicating images corresponding to each of the areas AR21 to AR23 of the second image P2 as information indicating the projected image PB when the original image PA is the second image P2 consisting of one image. According to this configuration, the second control program PG2 according to this embodiment achieves the same effects as the information output method according to this embodiment.

[0079] The projector 100 in this embodiment is equipped with a first processor 150A, which executes a first process of outputting first information J1 indicating one of the small images P11 to P14 as information indicating the projected image PB when the original image PA is a first image P1 in which the small images P11 to P14 are arranged as one image, and a second process of outputting second information J2 indicating images corresponding to each of some of the areas AR21 to AR23 of the second image P2 as information indicating the projected image PB when the original image PA is a second image P2 consisting of a single image.

[0080] According to this configuration, the projector 100 according to the present embodiment achieves the same effects as the information output method according to the present embodiment.

[0081] 8. Other Embodiments The above-described embodiment is a preferred embodiment, but is not limited to the above-described embodiment and various modifications are possible without departing from the spirit and scope of the present invention.

[0082] Moreover, each functional unit shown in Fig. 3 and Fig. 4 shows a functional configuration, and the specific implementation form is not particularly limited. In other words, it is not necessarily necessary to implement hardware corresponding to each functional unit individually, and it is of course possible to implement a configuration in which one processor executes a program to realize the functions of multiple functional units. Also, some of the functions realized by software in the above embodiment may be realized by hardware, or some of the functions realized by hardware may be realized by software. In addition, the specific detailed configurations of each of the other units of the projector 100 can also be changed arbitrarily without departing from the spirit of the projector.

[0083] In addition, the processing units in the flowchart shown in Fig. 7 are divided according to the main processing contents in order to facilitate understanding of the processing of the second control unit 210. There is no limitation to the manner of division or names of the processing units shown in the flowchart of Fig. 7, and the processing can be divided into more processing units according to the processing contents, or one processing unit can be divided to include more processes. In addition, the processing order of the above flowchart is not limited to the example shown in the figure.

[0084] The information output method can be realized by having the second processor 210A of the control device 200 execute a second control program PG2 corresponding to the information output method. The second control program PG2 can also be recorded on a computer-readable recording medium. The recording medium can be a magnetic or optical recording medium or a semiconductor memory device. Specifically, examples of the recording medium include portable or fixed recording media such as a flexible disk, HDD, CD-ROM (Compact Disk Read Only Memory), DVD, Blu-ray (registered trademark) Disc, magneto-optical disk, flash memory, card-type recording medium, etc. The recording medium may also be a non-volatile storage device such as a RAM, ROM, or HDD, which is an internal storage device provided in the image processing device. In addition, the second control program PG2 corresponding to the information output method can be stored in a server device or the like, and the information output method can be realized by downloading the second control program PG2 from the server device to the control device 200.

[0085] Furthermore, the information output method can be realized by having the first processor 150A included in the projector 100 execute a first control program PG1 corresponding to the information output method. Moreover, this first control program PG1 can also be recorded on a recording medium that is readable by a computer. As the recording medium, a magnetic or optical recording medium or a semiconductor memory device can be used. Specifically, examples of the recording medium include portable or fixed recording media such as flexible disks, HDDs, CD-ROMs, DVDs, Blu-ray (registered trademark) Discs, magneto-optical disks, flash memories, card-type recording media, etc. The recording medium may also be a non-volatile storage device such as a RAM, ROM, or HDD, which is an internal storage device provided in the image processing device. Moreover, the first control program PG1 corresponding to the information output method can be stored in a server device or the like, and the first control program PG1 can be downloaded from the server device to the projector 100 to realize the information output method.

[0086] 9. Summary of this Disclosure The following is a summary of this disclosure. (Appendix 1) An information output method comprising: when an original image is a first image in which a plurality of images are arranged as a single image, executing a first process to output first information indicating one of the plurality of images as information indicating a projected image; and when the original image is a second image consisting of a single image, executing a second process to output second information indicating an image corresponding to a partial region of the second image as information indicating the projected image.

[0087] This increases the degree of freedom in selecting the projection image, whether the original image is the first image or the second image, and therefore allows the projector to project a variety of images.

[0088] (Appendix 2) The information output method described in Appendix 1, wherein each of the multiple images is an image of an area surrounded by a boundary line, the first information is image information of one area surrounded by the boundary line in the first image, and the second information is image information corresponding to the portion of the area in the second image.

[0089] As a result, the first information and the second information are image information corresponding to the region, whether the original image is the first image or the second image. Therefore, the projector can easily project the projection image based on the first information and the second information. As a result, the processing of the projector can be simplified.

[0090] (Appendix 3) The information output method described in Appendix 1 or Appendix 2, wherein the first information is information indicating the first image and information indicating an area in the first image corresponding to the one image, and the second information is information indicating the second image and information indicating the part of the area in the second image.

[0091] This allows the projector to easily generate a projection image from each of the first information and the second information, regardless of whether the original image is the first image or the second image. Therefore, the projector can easily project a projection image based on the first information and the second information. As a result, the processing of the projector can be simplified.

[0092] (Appendix 4) An information output method as described in any one of Appendix 1 to Appendix 3, comprising: generating a first composite image by overlapping or arranging two images of the plurality of images; and outputting, in the first processing, third information indicating the first composite image instead of the first information as information indicating a projected image.

[0093] This allows the projector to project, as a projected image, a first composite image that is generated by overlapping or arranging two images among the multiple images. Therefore, it is possible to cause the projector to project a variety of images.

[0094] (Appendix 5) An information output method as described in any one of Supplementary Note 1 to Supplementary Note 4, comprising: generating a second composite image by superimposing or arranging an image corresponding to a first region of the second image and an image corresponding to a second region of the second image different from the first region; and outputting, in the second processing, fourth information indicating the second composite image instead of the second information as information indicating a projected image.

[0095] This allows the projector to project, as a projection image, a second composite image generated by superimposing or arranging an image corresponding to the first region of the second image and an image corresponding to the second region different from the first region of the second image, thereby making it possible for the projector to project a variety of images.

[0096] (Appendix 6) The information output method of any one of Appendix 1 to Appendix 5, wherein the first process includes selecting the one image from the plurality of images based on a user operation, and the second process includes selecting a partial area of ​​the second image based on a user operation.

[0097] This allows the user to select an image desired by the user from among the multiple images as the projection image, and allows the user to select an image of a region desired by the user in the second image as the projection image, thereby improving user convenience.

[0098] (Appendix 7) 7. The information output method according to claim 1, further comprising determining a shape of the projection image according to a projection surface onto which the projector projects the projection image.

[0099] This allows the shape of the projected image to be determined appropriately, thereby enabling the projector to project a variety of images.

[0100] (Appendix 8) A program that causes a processor to execute a first process of outputting, when an original image is a first image in which multiple images are arranged as a single image, first information indicating one of the multiple images as information indicating a projected image, and a second process of outputting, when the original image is a second image consisting of a single image, an image corresponding to a partial region of the second image as the projected image.

[0101] As a result, the program described in Supplementary Note 8 has the same effect as the information output method described in Supplementary Note 1.

[0102] (Appendix 9) A projector comprising a processor that executes a first process of outputting first information indicating one of a plurality of images as information indicating a projected image when an original image is a first image in which a plurality of images are arranged as a single image, and a second process of outputting second information indicating an image corresponding to a partial region of the second image as information indicating the projected image when the original image is a second image composed of a single image.

[0103] As a result, the projector described in Supplementary Note 9 has the same effect as the information output method described in Supplementary Note 1. [Explanation of symbols]
