[0009] Preferred embodiments of the present disclosure will be described below with reference to the accompanying drawings. Note that the dimensions and scale of each part in the drawings may differ from the actual dimensions and are shown schematically to facilitate understanding. Furthermore, the scope of the present disclosure is not limited to these embodiments unless otherwise specified in the following description to the effect that the present disclosure is limited.

[0010] 1. First embodiment 1-1. Overview of multi-projection systems 1 is a diagram showing an outline of a system 100 used in a display method according to the first embodiment. The system 100 is a multi-projection system that projects an entire image GG, which is composed of a first projection image G1 and a second projection image G2, onto a projection surface SC.

[0011] The projection surface SC is the surface of an object such as a screen. In the example shown in Fig. 1, the projection surface SC is a flat surface. However, the projection surface SC is not limited to a flat surface and may be, for example, a curved surface.

[0012] As shown in FIG. 1 , the system 100 includes a first projector 10-1, a second projector 10-2, and a terminal device 30. The first projector 10-1 is an example of a "projector." Hereinafter, the first projector 10-1 and the second projector 10-2 may be referred to as the projector 10 without distinction. Note that, in the present embodiment, an example is given in which the system 100 includes two projectors 10, but the number is not limited to this, and may be three or more. In other words, the entire image GG may include images projected from three or more projectors 10.

[0013] The first projector 10-1 is a display device that projects a first projection image G1 indicated by video data IMG1 output from the terminal device 30 onto a projection surface SC. On the other hand, the second projector 10-2 is a display device that projects a second projection image G2 indicated by video data IMG2 output from the terminal device 30 onto the projection surface SC.

[0014] The first projected image G1 and the second projected image G2 are arranged in this order in the first direction DR1 to form a whole image GG. The first projected image G1 and the second projected image G2 are spliced together and projected onto the projection surface SC so that the whole image GG displays a single image. In the example shown in FIG. 1, the whole image GG forms a rectangle with the first direction DR1 as its horizontal direction and a second direction DR2 perpendicular to the first direction DR1 as its vertical direction. The first projected image G1 is projected onto the left region of the projection surface SC in FIG. 1, while the second projected image G2 is projected onto the right region of the projection surface SC in FIG. 1. A portion of the first projected image G1 including the right edge in FIG. 1 and a portion of the second projected image G2 including the left edge in FIG. 1 are spliced together. That is, a part of the first projected image G1 including the right edge in FIG. 1 overlaps with a part of the second projected image G2 including the left edge in FIG.

[0015] A portion of the first projected image G1 and a portion of the second projected image G2 overlap each other in an overlapping region R. The overlapping region R is an area where a blending process is performed to make the seam between the first projected image G1 and the second projected image G2 less noticeable. In this way, the system 100 executes a display method in which a portion of the first projected image G1 projected onto the projection surface SC from the first projector 10-1 and a portion of the second projected image G2 projected onto the projection surface SC from the second projector 10-2 are superimposed in the overlapping region R on the projection surface SC.

[0016] In this embodiment, the first projector 10-1 is the main projector and controls the operation of the second projector 10-2, which is the sub-projector. The first projector 10-1 also has a setting function for setting the resolution and aspect ratio of the overall image GG. In this setting function, the first projector 10-1 can accept a selection operation for selecting one resolution from multiple resolutions that the first projector 10-1 can project. Based on the selection operation, the first projector 10-1 sets the resolution of each of the first projected image G1 and the second projected image G2, and displays multiple options for selecting one of multiple combinations of the resolution and aspect ratio of the overall image GG. The second projector 10-2 may have a different configuration from the first projector 10-1, as long as its operation can be controlled by the first projector 10-1. When the system 100 includes three or more projectors 10, one projector 10 of the three or more projectors 10 is the main projector, and the other two or more projectors 10 are sub-projectors. In the following, the resolution that can be projected by the projector 10 may be referred to as the "panel resolution," the "number of panel pixels," or the "screen type." The aspect ratio of the entire image GG may be referred to as the "combined aspect ratio."

[0017] The terminal device 30 is a device that has the function of dividing video data showing one image into multiple video data to be projected by multiple projectors 10, and the function of supplying each of the video data resulting from the division process to the corresponding projector 10.

[0018] Terminal device 30 of the present embodiment divides video data showing one image into video data IMG1 and video data IMG2, and then supplies video data IMG1 to first projector 10-1 and video data IMG2 to second projector 10-2.

[0019] 1, the terminal device 30 is a notebook computer having a liquid crystal display. However, the terminal device 30 is not limited to a notebook computer and may be, for example, a desktop computer, a smartphone, a tablet terminal, a video playback device, a DVD (Digital Versatile Disk) player, a Blu-ray Disc player, a hard disk recorder, a television tuner device, a CATV (Cable television) set-top box, a video game console, etc.

[0020] 1-2.Projector FIG. 2 is a block diagram of a first projector 10-1 according to the first embodiment. In addition to the first projector 10-1, FIG. 2 also shows the connection state of a second projector 10-2 and a terminal device 30 to the first projector 10-1. Note that while FIG. 2 representatively shows the configuration of the first projector 10-1, the configuration of the second projector 10-2 is the same as that of the first projector 10-1 except that it is a sub-device, and in the following description of the components, video data IMG1 can be read as video data IMG2. In the following, regarding the components of the projector 10, the components of the first projector 10-1 and the second projector 10-2 may be distinguished from each other by adding a suffix "-1" to the reference numeral of the component of the first projector 10-1 or adding a suffix "-2" to the reference numeral of the component of the second projector 10-2.

[0021] The first projector 10-1 is a projector used to superimpose a portion of the first projection image G1 projected onto the projection surface SC from the first projector 10-1 and a portion of the second projection image G2 projected onto the projection surface SC from the second projector 10-2 in an overlap area R on the projection surface SC.

[0022] 2, the first projector 10-1 has a storage device 11, a processing device 12, a communication device 13, an image processing circuit 14, an optical device 15, an operation device 16, and an imaging device 17. These are connected to each other so that they can communicate with each other.

[0023] The storage device 11 is a storage device that stores programs executed by the processing device 12 and data processed by the processing device 12. The storage device 11 includes, for example, a hard disk drive or a semiconductor memory. Note that part or all of the storage device 11 may be provided in an external storage device or server outside the first projector 10-1.

[0024] The storage device 11 stores a program PR1 and setting information D1.

[0025] The program PR1 is a program for executing a display method, which will be described in detail later. That is, the program PR1 is a program for superimposing a portion of a first projection image G1 projected onto the projection surface SC from the first projector 10-1 and a portion of a second projection image G2 projected onto the projection surface SC from the second projector 10-2 in an overlapping area R on the projection surface SC. The setting information D1 is information indicating the resolution and aspect ratio of the entire image GG.

[0026] The processing device 12 is a processing device that has a function of controlling each unit of the first projector 10-1 and a function of processing various data. The processing device 12 is configured to include a processor such as a CPU (Central Processing Unit). The processing device 12 may be configured with a single processor or multiple processors. Some or all of the functions of the processing device 12 may be realized by hardware such as a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The processing device 12 may be integrated with the image processing circuit 14.

[0027] The communication device 13 is a communication device capable of communicating with various devices, and acquires video data IMG1 from the terminal device 30 and communicates with the second projector 10-2. For example, the communication device 13 is a wired communication device such as a wired LAN (Local Area Network), USB (Universal Serial Bus), or HDMI (High Definition Multimedia Interface), or a wireless communication device such as LPWA (Low Power Wide Area), wireless LAN including Wi-Fi, or Bluetooth. "HDMI," "Wi-Fi," and "Bluetooth" are all registered trademarks.

[0028] The image processing circuit 14 performs necessary processing on the video data IMG1 from the communication device 13 and inputs the data to the optical device 15. The image processing circuit 14 has, for example, a frame memory (not shown), and loads the video data IMG1 into the frame memory, appropriately performs various processes such as resolution conversion, resizing, and distortion correction, and inputs the data to the optical device 15. Here, the image processing circuit 14 performs processing to adjust the resolution and aspect ratio of the entire image GG based on the setting information D1 stored in the storage device 11. Note that the image processing circuit 14 also performs processing such as OSD (On Screen Display) processing, which generates image information for menu display or operation guides, etc., and combines it with the video data IMG1, as necessary.

[0029] The optical device 15 is a device that projects image light onto the projection surface SC, and includes a light source 15a, a light modulator 15b, and a projection optical system 15c.

[0030] The light source 15a includes a light source such as a halogen lamp, a xenon lamp, an ultra-high pressure mercury lamp, an LED (Light Emitting Diode), or a laser light source, and emits red, green, and blue light, respectively. The light modulator 15b renders an image based on video data IMG1 supplied from the terminal device 30. The light modulator 15b includes three light modulation elements corresponding to red, green, and blue. Each light modulation element has, for example, a first side and a second side intersecting the first side. The first side is, for example, a horizontal side of the light modulation element, and the second side is, for example, a vertical side of the light modulation element. Each light modulation element has a plurality of pixels arranged in a matrix. The plurality of pixels are arranged in a matrix in a third direction along the first side and a fourth direction along the second side. Here, the third direction corresponds to the first direction DR1, and the fourth direction corresponds to the second direction DR2. Each light modulation element is, for example, a transmissive liquid crystal panel, a reflective liquid crystal panel, or a DMD (digital mirror device), and generates image light of each color by modulating light of the corresponding color. The image light of each color generated by the light modulator 15b is combined by a color combining optical system to become full-color image light. The projection optical system 15c is an optical system including a projection lens and the like that focuses and projects the full-color image light from the light modulator 15b onto the projection surface SC. The image drawn on the light modulator 15b, i.e., the drawn image, is projected onto the projection surface SC via the projection lens.

[0031] The operation device 16 is a device that accepts operations from a user. For example, the operation device 16 includes an operation panel and a remote control receiver, both not shown. The operation panel is provided on the exterior housing of the first projector 10-1, and outputs a signal based on an operation from the user. The remote control receiver receives an infrared signal from a remote control, also not shown, decodes the infrared signal, and outputs a signal based on the operation of the remote control.

[0032] The imaging device 17 is a digital camera having an imaging element such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The imaging device 17 captures an image of an area including an area of the image light projected from the optical device 15 onto the projection surface SC.

[0033] In the first projector 10-1 described above, the processing device 12 functions as the setting unit 12a by executing the program PR1 stored in the storage device 11. In this way, the processing device 12 includes the setting unit 12a.

[0034] The setting unit 12a sets the resolution and aspect ratio of the entire image GG. Specifically, the setting unit 12a controls the operations of the image processing circuit 14 and the optical device 15 to display a setting image UI (described later) required for setting the resolution and aspect ratio of the entire image GG. In addition, the setting unit 12a executes processing required for setting the resolution and aspect ratio of the entire image GG based on an operation on the setting image UI by the operation device 16.

[0035] In this embodiment, the processing device 12 acquires imaging data by causing the imaging device 17 to capture an image of image light on the projection surface SC, and performs calculations required for processing such as correction processing of the image light using the acquired imaging data.

[0036] As described above, the first projector 10-1 includes the optical device 15 and the processing device 12 that controls the operation of the optical device 15.

[0037] 1-3.Display method FIG. 3 is a flowchart showing the flow of the display method according to the first embodiment. The display method is performed by the processing device 12 executing the program PR1 using the above-described system 100. As shown in FIG. 3, the display method includes steps S11 to S16. That is, the processing device 12 of the first projector 10-1 executes steps S11 to S16. The program PR1 also causes the processing device 12, which is an example of a computer, to execute steps S11 to S16. The computer is not limited to the processing device 12 as long as it has a function of controlling the operation of the first projector 10-1. For example, it may be an external personal computer connected to the first projector 10-1.

[0038] More specifically, first, in step S11, the setting unit 12a displays a settings image UI, which will be described later. In this embodiment, this display is performed by the setting unit 12a controlling the driving of the image processing circuit 14 and the optical device 15 to project a settings image UI-1, which will be described later and is shown in FIG. 4, onto the projection surface SC as a first projection image G1. Step S11 is started, for example, when the first projector 10-1 is started or a predetermined operation is performed on the operation device 16.

[0039] After step S11, in step S12, the setting unit 12a determines whether or not a selection operation for selecting one resolution from a plurality of resolutions that can be projected by the first projector 10-1 has been received. This selection operation is performed using a settings image UI-2 shown in FIG. 5, which will be described later. Step S12 is repeated until the selection operation is performed (step S12: NO). Note that in step S12, the terminal device 30 may receive the selection operation. In this case, the settings image UI-2 shown in FIG. 5, which will be described later, may be displayed on the liquid crystal display of the terminal device 30, or may be projected from the first projector 10-1.

[0040] If a selection operation has been performed (step S12: YES), in step S13, the setting unit 12a executes the process of determining the resolution of each of the first projection image G1 and the second projection image G2 based on the selection operation in step S12. Specifically, based on the selection operation in step S12, the first projector 10-1 determines the maximum resolution that it should project, i.e., the first resolution, and directly transmits information indicating the first resolution to the second projector 10-2. This allows the second projector 10-2 to also determine the maximum resolution that it should project, i.e., the first resolution. Note that in step S13, the information indicating the first resolution may be temporarily transmitted from the first projector 10-1 to the terminal device 30, and then the information indicating the first resolution may be transmitted from the terminal device 30 to the second projector 10-2.

[0041] After step S13, in step S14, the setting unit 12a executes the process of displaying a plurality of options S2 (described later) for selecting one of a plurality of sets of resolution and aspect ratio of the entire image GG configured by the first projection image G1 and the second projection image G2. In this embodiment, this display is performed by controlling the driving of the image processing circuit 14 and the optical device 15 by the setting unit 12a to project a setting image UI-5 (described later in FIG. 8) onto the projection surface SC as the first projection image G1.

[0042] After step S14, in step S15, the setting unit 12a determines whether or not one option S2 is selected from a plurality of options S2 described below. Step S15 is repeated until an operation to confirm the selection of one option S2 is performed (step S15: NO).

[0043] If one option S2 is selected (step S15: YES), in step S16, the setting unit 12a sets the set of resolution and aspect ratio corresponding to the selected option S2 as the resolution and aspect ratio of the whole image GG. This setting content is stored in the storage device 11 as setting information D1.

[0044] The above is the flow of the display method. An example of the settings image UI used in this display method will be described below with reference to Figs. 4 to 8. Figs. 4 to 8 show settings images UI-1 to UI-5 that change depending on the progress of the display method. Hereinafter, the settings images UI-1 to UI-5 may be referred to as the settings image UI without distinction. Note that the settings image UI is not limited to the examples shown in Figs. 4 to 8.

[0045] 4 is a diagram showing an example of a settings image UI In step S11, for example, a settings image UI-1 is displayed as shown in FIG.

[0046] The UI setting image is a GUI (Graphical User Interface) image for various settings of the first projector 10-1, and can accept operations using the operation device 16. The content of the UI setting image changes in response to the operations.

[0047] The settings image UI-1 has tabs T-1 to T-7, an area Ra, and an area Rb.

[0048] Each of the tabs T-1 to T-7 is a display that can be selected by operating the operation device 16. Tab T-1 is a display for setting image quality. Tab T-2 is a display for setting video. Tab T-3 is a display for basic settings. Tab T-4 is a display for advanced settings. Tab T-5 is a display for network settings. Tab T-6 is a display for setting various information. Tab T-7 is a display for initializing settings.

[0049] Of the tabs T-1 to T-7, the tab T-4 is operated when configuring settings related to the resolution and aspect ratio of the entire image GG. Note that, of the tabs T-1 to T-7, the displays other than the tab T-4 are used as needed and may be omitted.

[0050] When tab T-4 is selected, area Ra is displayed first. Area Ra has button group BG1 and button B2. Button group BG1 is a display for settings that should be performed first in the extended settings, and includes button B1. Button B1 is a display for accepting an operation to change the content of the settings image UI to content for setting the resolution, i.e., screen type, of the first projector 10-1. Button B2 is a display for accepting an operation to return the content of the settings image UI to the state before the previous operation.

[0051] The area Rb is a display that explains how to operate the operation device 16 for the settings image UI.

[0052] 5 is a diagram for explaining a selection operation on the settings image UI. When button B1 is operated on the settings image UI-1 shown in FIG. 4, a settings image UI-2 is displayed in step S12 as shown in FIG.

[0053] The settings image UI-2 is similar to the settings image UI-1 except that it has an area Rc instead of the tabs T-1 to T-7 and the area Ra of the settings image UI-1, and has areas Rb and Rc.

[0054] Area Rc is a display for accepting a selection operation for selecting one resolution from a plurality of resolutions that can be projected by first projector 10-1. Area Rc includes a plurality of options S1 and a button B2.

[0055] The multiple options S1 correspond one-to-one to the multiple resolutions that can be projected by the first projector 10-1, and can be alternatively selected by operating the operation device 16. In the example shown in Fig. 5, the multiple options S1 correspond to resolutions according to aspect ratios of 4:3, 16:6, 16:9, 16:10, and 21:9.

[0056] Each option S1 is an option for specifying how many pixels to use in the light modulation element of the first projector 10-1, that is, an option for specifying a resolution. Therefore, in this embodiment, what is displayed in the area Rc as each option S1 is an aspect ratio, and each aspect ratio is previously associated with a resolution in the third direction (first direction DR1) and the fourth direction (second direction DR2). That is, a pair is formed by associating each aspect ratio with each resolution. For example, "4:3" among the multiple options S1 is associated with a resolution of 2880px x 2160px. Here, px is a unit indicating the number of pixels or resolution. Therefore, when "4:3" is selected, the first projector 10-1 uses, for example, a maximum of 2880 pixels in the third direction and a maximum of 2160 pixels in the fourth direction among the multiple pixels. Therefore, for example, by selecting "4:3" from the multiple options S1, the user can set the maximum resolution of the first projection image G1 that can be projected by the first projector 10-1 to 2880px in the first direction DR1 and 2160px in the second direction DR2.

[0057] The above-mentioned resolution of 2880px x 2160px is an example of a first resolution. The first resolution includes a first resolution in a first direction DR1 (e.g., 2880px) and a first resolution in a second direction DR2 (e.g., 2160px). The first resolution in the first direction DR1 is an example of the number of pixels Wa in the horizontal direction of the optical modulator 15b (described later), and the first resolution in the second direction DR2 is an example of the number of pixels Ha in the vertical direction of the optical modulator 15b (described later). Furthermore, the number of options S1 to be displayed, the display mode, the contents of the sets of corresponding resolutions and aspect ratios, etc. are not limited to the example shown in FIG. 5 and are arbitrary.

[0058] When one option S1 out of the plurality of options S1 is selected, it is determined in the above-mentioned step S12 that a selection operation has been performed (step S12: YES).

[0059] Fig. 6 is a diagram illustrating the settings image UI-3 after the resolution has been set. When button B2 is operated after a selection operation is performed on the settings image UI-2 shown in Fig. 5, the settings image UI-3 is displayed as shown in Fig. 6 during the period from step S12 to step S14.

[0060] The settings image UI-3 is similar to the settings image UI-1 except that it has an area Rd instead of the area Ra of the settings image UI-1, and has tabs T-1 to T-7, an area Rb, and an area Rd.

[0061] Area Rd is a display for multi-projection settings. Area Rd includes a plurality of button groups BG2 and button B2. Button group BG2 is a display for settings to be performed after setting the resolution of first projector 10-1 in extended settings, and includes button B3. Button B3 is a display for accepting an operation to change the content of the settings image UI to content for performing settings related to the entire image GG.

[0062] Fig. 7 is a diagram for explaining the setting of the set of resolution and aspect ratio of the entire image GG. When button B3 is operated on the setting image UI-3 shown in Fig. 6, a setting image UI-4 is displayed as shown in Fig. 7 during the period from step S12 to step S14.

[0063] The settings image UI-4 is similar to the settings image UI-3 except that it has an area Re instead of the area Rd of the settings image UI-3, and has tabs T-1 to T-7, an area Rb, and an area Re.

[0064] Area Re is a display for settings related to the entire image GG. Area Re includes a plurality of button groups BG3 and a button B2. Button group BG3 is a display for various settings related to the entire image GG, and includes a button B4. Button B4 is a display for accepting an operation to change the contents of the settings image UI to contents for setting the resolution and aspect ratio of the entire image GG.

[0065] Fig. 8 is a diagram showing an example of displaying multiple options S2 for combinations of resolution and aspect ratio of the entire image GG. When button B4 is operated on the settings image UI-4 shown in Fig. 7, settings image UI-5 is displayed in step S14 as shown in Fig. 8. Fig. 8 shows settings image UI-5 when a resolution (aspect ratio) of 3840 x 1644 (21:9) is selected in step S12. Note that 3840 x 1644 indicates 3840px x 1644px.

[0066] The settings image UI-5 is similar to the settings image UI-1 except that it has an area Rf instead of the tabs T-1 to T-7 and the area Ra of the settings image UI-1, and has areas Rb and Rf.

[0067] The area Rf is a display for accepting an operation to select one of a plurality of combinations of the resolution and aspect ratio of the entire image GG. The area Rc includes a plurality of options S2 and a button B2.

[0068] The multiple options S2 correspond one-to-one to multiple sets of resolutions and aspect ratios that can be projected by the first projector 10-1 and the second projector 10-2, and can be alternatively selected by operating the operation device 16. In the example shown in FIG. 8, the multiple options S2 are: A pair of 21:9 aspect ratio and 3440x1440 resolution (EDID), Aspect ratio 21:9 and resolution (EDID) 2560 x 1080 pair, Aspect ratio 16:6 and resolution (EDID) 2880 x 1080 pair, Aspect ratio 16:6 and resolution (EDID) 1920 x 720 pair, A pair of 3:1 aspect ratio and 3240 x 1080 resolution (EDID), Aspect ratio 32:10 and resolution (EDID) 3456 x 1080 pair, Aspect ratio 21:9 and resolution (EDID) 3200 x 900 pair, Corresponds to.

[0069] Note that the number of options S2 to be displayed, the display format, the contents of the corresponding sets of resolution and aspect ratio, etc. are not limited to the example shown in FIG. 8 and are arbitrary. EDID stands for Extended Display Identification Data. That is, in this embodiment, EDID includes resolution. The above-mentioned resolution of 3440 x 1440 is an example of a second resolution, and the unit is px. The second resolution includes a second resolution in the first direction DR1 (e.g., 3440 px) and a second resolution in the second direction DR2 (e.g., 1440 px). The second resolution in the first direction DR1 is an example of the number of pixels W of the entire image GG described below, and the second resolution in the second direction DR2 is an example of the number of pixels H of the entire image GG described below.

[0070] When one option S2 out of the multiple options S2 is selected by operation of the operation device 16, it is determined in the above-mentioned step S15 that one option S2 has been selected (step S15: YES). Furthermore, in step S16, setting information D1 indicating a set of resolution and aspect ratio corresponding to the selected option S2 is generated. As a result, the set of resolution and aspect ratio indicated by the setting information D1 is set as the resolution and aspect ratio of the entire image GG.

[0071] In such a setting image UI-5, the user needs to visually recognize the multiple options S2 and then select one option S2 from the multiple options S2 by operating the operation device 16. Therefore, in order to improve usability, in step S14, the setting unit 12a changes the display mode of the multiple options S2 according to the condition of at least one parameter that defines the overall image GG.

[0072] That is, in step S14, the setting unit 12a changes the display mode of option S2-a, which is an option S2 corresponding to a combination of resolution and aspect ratio that satisfies the condition of at least one parameter defining the entire image GG, from the display mode of option S2-b, which is another option S2, among the multiple options S2. This makes it easier to intuitively grasp which resolution of the entire image GG satisfies the condition, thereby improving usability.

[0073] It is preferable to disable the operation of selecting an option S2 that corresponds to a combination of resolution and aspect ratio that satisfies the conditions from among the multiple options S2, thereby preventing the user from accidentally selecting an entire image GG that does not have the number of pixels X, which is the optimal overlap width as described below.

[0074] In the example shown in FIG. 8, option S2-a is displayed in a manner indicating that it is selectable, while option S2-b is displayed in a manner indicating that it is not selectable. Note that the display manner of options S2-a and S2-b is not limited to the example shown in FIG. 8, and may be, for example, a manner in which option S2-b is displayed in a manner that makes it less noticeable than option S2-a by graying it out, etc. Also, option S2-b corresponding to a combination of resolution and aspect ratio that does not satisfy the condition may be selectable. However, in this case, option S2-a corresponding to a combination of resolution and aspect ratio that satisfies the condition must be selectable. Also, in this case, option S2-b is preferably displayed in a manner that indicates precautions, etc. regarding the display manner of the entire image GG if selected.

[0075] FIG. 9 is a diagram illustrating the relationship between the resolution and aspect ratio of the overall image GG and the resolution and aspect ratio of the modulators 15b-1 and 15b-2. Let W be the number of pixels of the overall image GG in the first direction DR1, Ha be the number of pixels in the vertical direction (fourth direction) of the optical modulator 15b, Hb be the number of pixels in the vertical direction (third direction) of the resolution corresponding to option S2, and Wb be the number of pixels in the horizontal direction of the resolution corresponding to option S2. The number of pixels W is expressed as W = Ha × (Wb / Hb). Wb / Hb corresponds to the aspect ratio of the overall image GG desired to be constructed by the user. The number of pixels Ha can also be expressed as the number of pixels in the second direction DR2 at the resolution projectable by the projector 10. The number of pixels Ha is an example of a first resolution in a second direction perpendicular to the first direction. The number of pixels W of the overall image GG in the first direction DR1 is an example of a second resolution of the overall image in the first direction.

[0076] Furthermore, when the number of pixels in the overlapping region R in the first direction DR1 is X and the number of pixels in the horizontal direction of the optical modulator 15b is Wa, the number of pixels X is expressed as X = (Wa + Wa) - W = (Wa × 2) - W. The number of pixels in the overlapping region R in the first direction DR1 is an example of the resolution of the overlapping region in the first direction. The number of pixels Wa is an example of the first resolution of the first projected image in the first direction DR1. The number of pixels Wa is the maximum number of pixels used in the first direction DR1 of the optical modulator 15b. In other words, the number of pixels in the overlapping region R in the first direction DR1 is calculated based on the number of pixels Wa of the first projected image G1 in the first direction DR1, the number of pixels Wa of the second projected image G2 in the first direction DR1, the number of pixels Ha in the second direction DR2, and the aspect ratio Wb / Hb of the entire image GG. The number of pixels Wa can also be expressed as the number of pixels in the first direction DR1 at the resolution that the projector 10 can project.

[0077] Here, if the first ratio X / Wa, which is the ratio of the number of pixels X to the number of pixels Wa, is too small, it is impossible to ensure a sufficient number of pixels X. For example, depending on the resolution of the imaging device 17, it may be difficult to correct the image of the overlapping region R using the imaging results of the imaging device 17. On the other hand, if the first ratio X / Wa is too large, it may be difficult to obtain the advantage of constructing the entire image GG using the first projected image G1 and the second projected image G2. The first ratio X / Wa indicates how many of the number of pixels X in the number of pixels Wa of the first projected image G1 in the first direction DR1 are occupied by the overlapping region R.

[0078] Therefore, in step S14, the first ratio X / Wa is used as a parameter for determining whether option S2 is option S2-a. That is, the parameter used in step S14 is the first ratio X / Wa, which is the ratio of the number of pixels X in the overlapping region R in the first direction DR1 to the number of pixels Wa in the first projected image G1 in the first direction DR1, which is the direction in which the first projected image G1 and the second projected image G2 are aligned. The condition in step S14 is that the first ratio X / Wa falls outside the first range. This makes it easy to determine which part of the overall image GG does not have the optimal overlap width. Here, the number of pixels X in the overlapping region R in the first direction DR1 is calculated according to the aforementioned formula based on the resolutions of the first projected image G1 and the second projected image G2 based on the selection operation and the aspect ratio of the overall image GG.

[0079] Here, the lower limit of the first range is preferably 12.5%. This ensures a sufficient number of pixels X. The lower limit of the first range is an example of a first value greater than zero. The upper limit of the first range is preferably 70%. The upper limit of the first range is an example of a second value greater than zero and greater than the first value. In other words, when the first ratio X / Wa falls outside the first range, it means that the first ratio X / Wa is less than the lower limit of the first range and greater than the upper limit of the first range. This makes it easy to obtain the advantage of constructing the entire image GG using the first projected image G1 and the second projected image G2.

[0080] 10 and 11 are diagrams for explaining examples of combinations of the resolution and aspect ratio of the entire image GG.

[0081] Fig. 10 shows the relationship between the resolution and aspect ratio of the entire image GG and the number of pixels W, X and the first ratio X / Wa when the resolution (aspect ratio) selected in step S12 is 3840 × 1644 (21:9). Fig. 11 shows the relationship between the resolution and aspect ratio of the entire image GG and the number of pixels W, X and the first ratio X / Wa when the resolution (aspect ratio) selected in step S12 is 2880 × 1440 (16:6).

[0082] 10 and 11, among the multiple combinations of resolution and aspect ratio of the entire image GG, there is a combination for which the first ratio X / Wa exceeds 70%. Therefore, if the resolution (aspect ratio) selected in step S12 is 3840×1644 (21:9) or 2880×1440 (16:6), in step S14, the option S2 corresponding to the combination of resolution and aspect ratio of the entire image GG for which the first ratio X / Wa exceeds 70% becomes option S2-b.

[0083] 12 is a diagram showing another example of displaying multiple options S2 for combinations of resolution and aspect ratio of the entire image GG. In FIG. 12, a settings image UI-5 is shown when a resolution (aspect ratio) of 3840×2160 (16:9) is selected in step S12.

[0084] When the number of pixels of the entire image GG in the second direction DR2 is H, if the overlapping area R is secured and the number of pixels H is equal to or greater than the number of pixels Ha, i.e., if the second ratio H / Ha, which is the ratio of the number of pixels H to the number of pixels Ha, is greater than or equal to 0 and less than 1, upper and lower black bands, which are areas not used for drawing, will appear at the top and bottom of the first projection image G1 and the second projection image G2.

[0085] For example, suppose that in step S13, the pixel count Wa = 3456px and the pixel count Ha = 2160px are determined for the first projector 10-1 and the second projector 10-2, respectively. Furthermore, suppose that a combination of an aspect ratio of 32:10 and a resolution (EDID) of 3456 × 1080 is selected as option S2. In this case, the pixel count W of the entire image GG is Ha × (Wb / Hb) = 2160 × (3456 / 1080) = 6912px. This value is exactly twice the pixel count Wa. If this value is left unchanged, even if an entire image GG with an aspect ratio of 32:10 and a resolution (EDID) of 3456 × 1080 is constructed, the pixel count X of the overlap region R will be zero, i.e., the first ratio X / Wa = 0, which would not satisfy the preferred lower limit of 12.5%.

[0086] Therefore, in this embodiment, the number of pixels W of the actual entire image GG is corrected so that, for example, 12.5% of 3456px, or 432px, is secured as the number of pixels X of the overlapping region R. Specifically, 6480px, obtained by subtracting 432px from 6912px, is adopted as the number of pixels W of the actual entire image GG. In this case, since the user ultimately wants to construct an entire image GG having an aspect ratio of 32:10, if the number of pixels W of the entire image GG is 6480px, the number of pixels H of the entire image GG is calculated as 6480px (W) × (10 / 32) = 2025px. This 2025px corresponds to H in the second ratio H / Ha, which will be described later. Meanwhile, as described above, since the number of pixels Ha = 2160px was determined in step S13, the first projector 10-1 and the second projector 10-2 can originally use a maximum number of pixels Ha = 2160px. However, as shown in the above calculation, in order to construct an entire image GG with an aspect ratio of 32:10, the pixel count H of the entire image GG should be 2025px. Therefore, the pixel count H is less than the pixel count Ha in the second direction DR2 by 135px, calculated by subtracting 2025px from 2160px. Therefore, black bands corresponding to the difference between the pixel count H and the pixel count Ha appear in the first projected image G1 and the second projected image G2 in the second direction DR2. In this case, if the second ratio H / Ha is defined, the second ratio H / Ha is calculated as 2025 / 2160=0.9375. In other words, the second ratio H / Ha can be considered an index for determining whether black bands appear in the first projected image G1 and the second projected image G2 in the second direction DR2. If black bands do not appear in the first projected image G1 and the second projected image G2 in the second direction DR2, the second ratio H / Ha is greater than 1. That is, when the pixel count H is greater than the pixel count Ha, black bands do not appear in the first projected image G1 and the second projected image G2. When the pixel count H is greater than the pixel count Ha, some of the pixels that make up the pixel count H are thinned out so that the pixel count falls within the range of the pixel count Ha.

[0087] Therefore, in step S14, the second ratio H / Ha is used as a parameter of the condition for determining whether option S2 is option S2-a. That is, the parameter used in step S14 is the second ratio H / Ha of the number of pixels H of the entire image GG in the second direction DR2, which is a direction perpendicular to the first direction DR1 in which the first projected image G1 and the second projected image G2 are aligned, to the number of pixels Ha of the first projected image G1 in the second direction DR2. The number of pixels H of the entire image GG in the second direction DR2 is an example of a second resolution of the entire image GG in the second direction DR2. The number of pixels H of the entire image GG in the second direction DR2 is calculated based on the number of pixels W of the entire image GG in the first direction DR1 and the aspect ratio of the entire image GG. Furthermore, the condition in step S14 is that the second ratio H / Ha is less than 1. This makes it easier to determine which entire images GG have black bars at the top and bottom. Since the second ratio H / Ha is a positive number, the condition may be set such that the second ratio H / Ha is equal to or greater than 0 and less than 1.

[0088] In the example shown in Figure 12, in step S14, the setting unit 12a differentiates the display mode of option S2-a, which is option S2 among the multiple options S2 and corresponds to a combination of resolution and aspect ratio that satisfies the conditions of at least one parameter that defines the entire image GG, from the display mode of option S2-c, which is another option S2.

[0089] Option S2-c is a display mode that indicates that, although it is selectable, upper and lower black bands, which are areas not used for drawing, will appear at the top and bottom of the first projection image G1 and the second projection image G2. In the example shown in FIG. 12, option S2-c is marked with an "!" symbol, and an explanation for the "!" symbol is displayed in the settings image UI. Note that the display mode of option S2-c is not limited to the example shown in FIG. 12, and may be, for example, grayed out to make it less noticeable than option S2-a. Also, option S2-c may be made unselectable, similar to option S2-b described above.

[0090] The parameters used in step S14 may include the first ratio X / Wa and the second ratio H / Ha described above. In this case, the conditions in step S14 are that the first ratio X / Wa falls outside the first range and that the second ratio H / Ha is equal to or greater than 0 and less than 1. This makes it easier to determine which overall images GG do not have the overlap width, which is the width of the optimal overlap region R, and which have black bars above and below.

[0091] Each of FIGS. 13 to 15 is a diagram for explaining an example of a combination of the resolution and aspect ratio of the entire image GG.

[0092] Fig. 13 shows the relationship between the resolution and aspect ratio of the entire image GG and the number of pixels W, X and the first ratio X / Wa when the resolution (aspect ratio) selected in step S12 is 3840 x 2160 (16:9). Fig. 14 shows the relationship between the resolution and aspect ratio of the entire image GG and the number of pixels W, X and the first ratio X / Wa when the resolution (aspect ratio) selected in step S12 is 3456 x 2160 (16:10). Fig. 15 shows the relationship between the resolution and aspect ratio of the entire image GG and the number of pixels W, X and the first ratio X / Wa when the resolution (aspect ratio) selected in step S12 is 2880 x 2160 (4:3).

[0093] 13 and 15, among the multiple combinations of resolution and aspect ratio of the entire image GG, there are combinations for which the second ratio H / Ha is equal to or greater than 1. Therefore, if the resolutions (aspect ratios) selected in step S12 are 3840×2160 (16:9), 3456×2160 (16:10), and 2880×2160 (4:3), in step S14, the option S2 corresponding to the combination of resolution and aspect ratio of the entire image GG for which the second ratio H / Ha is equal to or greater than 1 becomes option S2-c.

[0094] 2. Second embodiment A second embodiment of the present disclosure will be described below. In the following exemplary embodiment, for elements whose actions and functions are similar to those of the first embodiment, the reference numerals used in the description of the first embodiment will be used, and detailed descriptions of each element will be omitted as appropriate.

[0095] 16 is a block diagram of a terminal device 30A used in a display method according to the second embodiment. The terminal device 30A is an example of a "computer" and is configured similarly to the terminal device 30 of the first embodiment except that it executes a program PR2. Note that in this embodiment, the program PR1 of the first embodiment may be omitted.

[0096] 16, the terminal device 30A has a storage device 31, a processing device 32, a communication device 33, a display device 34, and an input device 35. These are connected to each other so that they can communicate with each other.

[0097] The storage device 31 is a storage device that stores programs executed by the processing device 32 and data processed by the processing device 32. The storage device 31 is configured to include, for example, a hard disk drive or a semiconductor memory. Note that part or all of the storage device 31 may be provided in an external storage device or server outside the terminal device 30A.

[0098] The storage device 31 stores a program PR2, setting information D1, and resolution information D2.

[0099] Program PR2 is a program for executing a display method that will be described later in detail with reference to Fig. 17. Resolution information D2 includes one or both of first information indicating the maximum number of resolutions that can be projected by first projector 10-1 and second information indicating the maximum number of resolutions that can be projected by second projector 10-2.

[0100] The processing device 32 is a processing device that has the function of controlling each unit of the terminal device 30A and the function of processing various types of data. The processing device 32 is configured to include a processor such as a CPU. The processing device 32 may be configured with a single processor or multiple processors. Furthermore, some or all of the functions of the processing device 32 may be realized by hardware such as a DSP, ASIC, PLD, or FPGA.

[0101] The communication device 33 is a communication device capable of communicating with various devices, and communicates with the first projector 10-1 and the second projector 10-2. For example, the communication device 33 is a wired communication device such as a wired LAN, USB, or HDMI, or a wireless communication device such as a wireless LAN including LPWA and Wi-Fi, or Bluetooth. "HDMI," "Wi-Fi," and "Bluetooth" are all registered trademarks.

[0102] The display device 34 displays various images under the control of the processing device 32. Here, the display device 34 has a display panel such as a liquid crystal display panel or an organic EL (electro-luminescence) display panel.

[0103] The input device 35 is a device that accepts operations from a user. For example, the input device 35 has a pointing device such as a touchpad, a touch panel, or a mouse. Here, if the input device 35 has a touch panel, it may also serve as the display device 34. Note that the input device 35 may be provided outside the terminal device 30A. Furthermore, the input device 35 may have other input devices such as a keyboard.

[0104] In the above terminal device 30A, the processing device 32 functions as the setting unit 32a by executing the program PR2 stored in the storage device 31. In this way, the processing device 32 includes the setting unit 32a.

[0105] The setting unit 32a sets the resolution and aspect ratio of the entire image GG. Specifically, the setting unit 32a acquires resolution information D2 based on one or both of the first information acquired from the first projector 10-1 and the second information acquired from the second projector 10-2, and displays a setting image UI necessary for setting the resolution and aspect ratio of the entire image GG based on the resolution information D2. The setting unit 32a also executes processing necessary for setting the resolution and aspect ratio of the entire image GG based on an operation on the setting image UI by the input device 35.

[0106] Fig. 17 is a flowchart showing the flow of a display method according to the second embodiment. The display method is performed by the processing device 32 executing the program PR2 using the terminal device 30A described above. As shown in Fig. 17, the display method includes steps S21 to S25. That is, the terminal device 30A executes steps S21 to S25. Furthermore, the program PR2 causes the terminal device 30A, which is an example of a computer, to execute steps S21 to S25.

[0107] More specifically, first, in step S21, the setting unit 32a displays a settings image UI. In this embodiment, this display is performed by causing the setting unit 32a to control the driving of the display device 34, thereby causing the display device 34 to display the settings image UI-1 shown in FIG. 4 described above. Step S21 is started, for example, in response to a predetermined operation on the input device 35.

[0108] After step S21, in step S22, the setting unit 32a acquires the resolution that can be projected by one or both of the first projector 10-1 and the second projector 10-2. This results in the acquisition of resolution information D2. This acquisition is performed by the setting unit 32a communicating with one or both of the first projector 10-1 and the second projector 10-2 via the communication device 33.

[0109] Thus, in step S22, the setting unit 32a acquires one or both of the first information indicating the maximum number of resolutions that can be projected by the first projector 10-1 and the second information indicating the maximum number of resolutions that can be projected by the second projector 10-2.

[0110] After step S22, in step S23, the setting unit 32a executes displaying of a plurality of options S2. In the present embodiment, this display is performed by controlling the driving of the display device 34 by the setting unit 32a to cause the display device 34 to display the setting image UI-5 shown in FIG. 8 described above.

[0111] Thus, in step S23, the setting unit 32a displays multiple options S2 for selecting one of multiple sets of resolution and aspect ratio of the overall image GG composed of the first projection image G1 and the second projection image G2 based on the first information or the second information.

[0112] Here, similar to step S14 in the first embodiment, step S23 differentiates the display mode of one of the multiple options S2 whose resolution and aspect ratio of the overall image GG corresponds to a set of resolutions and aspect ratios that can be displayed by the first projector 10-1 and the second projector 10-2 from the display mode of the other options S2.

[0113] After step S23, in step S24, the setting unit 32a determines whether or not one option S2 is selected from the multiple options S2, similar to step S15 described above. Step S24 is repeated until an operation to confirm the selection of one option S2 is performed (step S24: NO).

[0114] If one option S2 is selected (step S24: YES), in step S25, the setting unit 32a sets the set of resolution and aspect ratio corresponding to the selected option S2 as the resolution and aspect ratio of the entire image GG. This is stored in the storage device 31 as setting information D1. Then, the setting unit 32a transmits the setting information D1 stored in the storage device 31 to one or both of the first projector 10-1 and the second projector 10-2 via the communication device 33.

[0115] According to the second embodiment described above, by differentiating the display mode of the option S2 whose resolution and aspect ratio of the entire image GG correspond to a set of resolutions and aspect ratios that can be displayed by the first projector 10-1 and the second projector 10-2 from the display mode of the other options S2, it becomes easier to intuitively grasp which resolution of the entire image GG satisfies the conditions, thereby improving usability.

[0116] 3. Variations The above-described embodiments can be modified in various ways. Specific modifications that can be applied to the above-described embodiments are exemplified below. Two or more embodiments arbitrarily selected from the following examples can be combined as appropriate within the scope of not mutually contradictory.

[0117] 3-1. Variation 1 In the above-described embodiment, the first projected image G1 and the second projected image G2 are arranged horizontally, but the present invention is not limited to this. For example, the first projected image G1 and the second projected image G2 may be arranged vertically. That is, the first direction DR1 is not limited to the horizontal direction and may be, for example, the vertical direction. Furthermore, the first direction DR1 is not limited to the horizontal direction of the first projected image G1 or the second projected image G2 and may be, for example, the vertical direction of the first projected image G1 or the second projected image G2.

[0118] 3-2. Variation 2 In the above-described embodiment, each option S2 displays the resolution and aspect ratio of the entire image GG, but this is not limiting. Specifically, as long as the first projector 10-1 and the second projector 10-2 can recognize the resolution and aspect ratio of the entire image GG to be projected in response to the selection of option S2, each option S2 may display either the resolution or the aspect ratio of the entire image GG. For example, each option S2 may display only the aspect ratio, and a combination of an aspect ratio of 21:9 and a resolution (EDID) of 3440×1440 and a combination of an aspect ratio of 21:9 and a resolution (EDID) of 2560×1080 may be displayed as an aspect ratio of 21:9 (large resolution) and an aspect ratio of 21:9 (small resolution), respectively. As another example, each option S2 may display only the resolution of the entire image GG, i.e., the EDID.

[0119] 3-3. Variation 3 Furthermore, when at least one of the programs PR1 and PR2 is implemented using a computer included in the terminal device 30, the first projector 10-1, and / or the second projector 10-2, the programs executed by these computers can be configured as a computer-readable, non-transitory recording medium. Alternatively, the programs can be configured as a transmission medium for transmitting the programs executed by these computers. The recording medium can be a magnetic or optical recording medium or a semiconductor memory device. Specific examples include portable or fixed recording media such as flexible disks, hard disk drives (HDDs), CD-ROMs, digital versatile discs (DVDs), Blu-ray discs, magneto-optical discs, flash memory, and card-type recording media.
