Detailed implementation manners

[0028] Hereinafter, preferred implementation manners of the present disclosure will be described with reference to the drawings. In addition, in the drawings, the sizes and scales of the respective parts are appropriately different from the actual ones, and there are also parts schematically shown for easy understanding. In addition, as long as there is no description specifically limiting the gist of the present disclosure in the following description, the scope of the present disclosure is not limited to these manners.

[0029] 1. First implementation manner

[0030] 1-1. Outline of multi-projection system

[0031] Figure 1FIG. 0 is a schematic diagram showing a system 100 used in the display method according to the first embodiment. The system 100 is a multi-projection system that projects an overall image GG composed of a first projection image G1 and a second projection image G2 onto a projection surface SC.

[0032] The projection surface SC is the surface of an object such as a screen. In Figure 1 the example shown, the projection surface SC is a plane. In addition, the projection surface SC is not limited to a plane and may be a curved surface, for example.

[0033] As Figure 1 shown, 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 not be distinguished from each other and may be simply referred to as the projector 10. In addition, in the present embodiment, a mode in which the number of projectors 10 included in the system 100 is two is illustrated, but the present invention is not limited to this mode, and the number may be three or more. That is, the overall image GG may also include images projected from three or more projectors 10.

[0034] The first projector 10-1 is a display device that projects the first projection image G1 shown in the video data IMG1 output from the terminal device 30 onto the projection surface SC. On the other hand, the second projector 10-2 is a display device that projects the second projection image G2 shown in the video data IMG2 output from the terminal device 30 onto the projection surface SC.

[0035] The first projection image G1 and the second projection image G2 are arranged in the first direction DR1 in the order of the first projection image G1 and the second projection image G2 to form the overall image GG. Here, the first projection image G1 and the second projection image G2 are projected onto the projection surface SC in a mutually joined state so that the overall image GG displays one image. In Figure 1 the example shown, the overall image GG is rectangular with the first direction DR1 as the horizontal direction and the second direction DR2 perpendicular to the first direction DR1 as the vertical direction. In addition, the first projection image G1 is projected onto the Figure 1 left region of the projection surface SC, while the second projection image G2 is projected onto the Figure 1 right region of the projection surface SC. Moreover, a part of the first projection image G1 including the Figure 1 right end in the Figure 1 is joined to a part of the second projection image G2 including the Figure 1 left end in the Figure 1 That is, a part of the first projection image G1 including the

[0036] A part of such a first projected image G1 overlaps with a part of a second projected image G2 in an overlapping region R. The overlapping region R is a region where a fusion process is performed to make the seam between the first projected image G1 and the second projected image G2 inconspicuous. Thus, in the system 100, a display method is executed in which a part of the first projected image G1 projected from the first projector 10-1 onto the projection surface SC overlaps with a part of the second projected image G2 projected from the second projector 10-2 onto the projection surface SC in the overlapping region R on the projection surface SC.

[0037] In the present embodiment, the first projector 10-1 is the host and controls the operation of the second projector 10-2 as the slave. In addition, the first projector 10-1 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 of selecting one resolution from among a plurality of resolutions that the first projector 10-1 can project, and based on this selection operation, set the resolutions of the first projected image G1 and the second projected image G2, and display a plurality of options for selecting one group from among a plurality of groups of the resolution and aspect ratio of the overall image GG. In addition, the second projector 10-2 may have a structure that can be controlled by the first projector 10-1, and may also have a structure different from that of the first projector 10-1. When the number of projectors 10 included in the system 100 is three or more, one of the three or more projectors 10 is the host, and the other two or more projectors 10 are slaves, respectively. In addition, hereinafter, the resolution that the projector 10 can project may be referred to as "panel resolution", "panel pixel number", or "screen type". The aspect ratio of the overall image GG may be referred to as "combined aspect ratio".

[0038] The terminal device 30 is a device having a function of dividing image data representing one image into a plurality of image data to be projected by a plurality of projectors 10, and a function of supplying each piece of image data based on this division process to the corresponding projector 10.

[0039] After dividing the image data representing one image into image data IMG1 and image data IMG2, the terminal device 30 of the present embodiment supplies the image data IMG1 to the first projector 10-1 and supplies the image data IMG2 to the second projector 10-2.

[0040] In Figure 1In the example shown, the terminal device 30 is a notebook computer having a liquid crystal display. In addition, the terminal device 30 is not limited to a notebook computer, and may be, for example, a desktop computer, a smartphone, a tablet terminal, etc., and may also be a video playback device, a DVD (Digital Versatile Disk) player, a Blu-ray Disc player, a hard disk recorder, a television tuning device, a set-top box for CATV (Cable television), a video game console, etc.

[0041] 1-2. Projector

[0042] Figure 2 is a block diagram of the first projector 10-1 according to the first embodiment. In Figure 2 it, in addition to the first projector 10-1, the connection states of the second projector 10-2 and the terminal device 30 with respect to the first projector 10-1 are also shown. In addition, in Figure 2 it, the structure of the first projector 10-1 is representatively shown, but the structure of the second projector 10-2 is the same as that of the first projector 10-1 except that it is a slave unit, and in the following description of the structural elements, the video data IMG1 may be replaced with the video data IMG2. Hereinafter, regarding the structural elements of the projector 10, the structural elements of the first projector 10-1 and the structural elements of the second projector 10-2 may be distinguished by attaching the suffix "-1" to the reference numerals of the structural elements of the first projector 10-1 or attaching the suffix "-2" to the reference numerals of the structural elements of the second projector 10-2.

[0043] The first projector 10-1 is a projector used when a part of the first projection image G1 projected from the first projector 10-1 onto the projection surface SC overlaps with a part of the second projection image G2 projected from the second projector 10-2 onto the projection surface SC in the overlapping region R on the projection surface SC.

[0044] As Figure 2 shown, 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 a photographing device 17. They are connected in a manner capable of communicating with each other.

[0045] 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 is configured to include, for example, a hard disk drive or a semiconductor memory. In addition, part or all of the storage device 11 may also be provided in an external storage device or server, etc. of the first projector 10-1.

[0046] The program PR1 and the setting information D1 are stored in the storage device 11.

[0047] The program PR1 is a program for executing the display method described in detail later. That is, the program PR1 is a program for causing a part of the first projection image G1 projected onto the projection surface SC from the first projector 10-1 to overlap with a part of the second projection image G2 projected onto the projection surface SC from the second projector 10-2 in the overlapping area R on the projection surface SC. The setting information D1 is information indicating the resolution and aspect ratio of the overall image GG.

[0048] The processing device 12 is a processing device having a function of controlling each part 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), for example. In addition, the processing device 12 may be composed of a single processor or multiple processors. Further, part or all of the functions of the processing device 12 may be implemented 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). Additionally, the processing device 12 may be integrated with the image processing circuit 14.

[0049] The communication device 13 is a communication device capable of communicating with various devices, obtaining the video data IMG1 from the terminal device 30, or communicating 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), a USB (Universal Serial Bus), or an HDMI (High Definition Multimedia Interface), a wireless communication device such as an LPWA (Low Power Wide Area), a wireless LAN including Wi-Fi, or Bluetooth. "HDMI", "Wi-Fi", and "Bluetooth" are registered trademarks, respectively.

[0050] The image processing circuit 14 is a circuit that performs necessary processing on the image data IMG1 from the communication device 13 and inputs it to the optical device 15. The image processing circuit 14 has, for example, a frame memory (not shown), expands the image data IMG1 in the frame memory, and appropriately performs various processes such as resolution conversion processing, size adjustment processing, and distortion correction processing, and then inputs the processed data to the optical device 15. Here, the image processing circuit 14 performs processing to adjust the resolution and aspect ratio of the overall image GG based on the setting information D1 stored in the storage device 11. In addition, the image processing circuit 14 performs processing such as OSD (On Screen Display) processing that generates image information for menu display or operation guidance as needed and synthesizes it into the image data IMG1.

[0051] The optical device 15 is a device that projects image light onto the projection surface SC. The optical device 15 includes a light source 15a, a light modulator 15b, and a projection optical system 15c.

[0052] The light source 15a is configured to include, for example, a halogen lamp, a xenon lamp, an ultra-high pressure mercury lamp, an LED (Light Emitting Diode), or a laser light source, etc., and emits red, green, and blue light respectively. The light modulator 15b draws an image based on the image data IMG1 supplied from the terminal device 30. The light modulator 15b is configured to include three light modulation elements provided corresponding to red, green, and blue. Each light modulation element has, for example, a first side and a second side that intersects the first side. The first side is, for example, the horizontal side of the light modulation element, and the second side is the 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 Micromirror Device), etc., and generates image light of each color by modulating the light of the corresponding color. The image light of each color generated by the light modulator 15b is synthesized by a color synthesis optical system to become full-color image light. The projection optical system 15c is an optical system that includes a projection lens that forms an image of the full-color image light from the light modulator 15b on the projection surface SC and projects it. The drawn image drawn by the light modulator 15b is projected onto the projection surface SC via the projection lens.

[0053] The operation device 16 is a device that accepts operations from the user. For example, the operation device 16 includes an operation panel (not shown) and an infrared remote control light receiving unit. The operation panel is provided on the exterior housing of the first projector 10 and outputs a signal based on an operation from the user. The infrared remote control light receiving unit receives an infrared signal from a remote control (not shown), decodes the infrared signal, and outputs a signal based on the operation of the remote control.

[0054] 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 images a region including the image light projected onto the projection surface SC from the optical device 15.

[0055] In the above-described first projector 10-1, the processing device 12 functions as the setting unit 12a by executing the program PR1 stored in the storage device 11. Thus, the processing device 12 includes the setting unit 12a.

[0056] The setting unit 12a sets the resolution and aspect ratio of the overall 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 overall image GG. In addition, the setting unit 12a performs processing required for setting the resolution and aspect ratio of the overall image GG based on the operation of the operation device 16 on the setting image UI.

[0057] In the present embodiment, the processing device 12 obtains imaging data by imaging the image light on the projection surface SC using the imaging device 17, and performs operations required for processing such as correction processing of the image light using the obtained imaging data.

[0058] 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.

[0059] 1-3. Display Method

[0060] Figure 3 is a flowchart showing the flow of the display method according to the first embodiment. This display method is performed using the above-described system 100 and by the processing device 12 executing the program PR1. As Figure 3As shown, 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. In addition, the program PR1 causes the processing device 12, which is an example of a computer, to execute steps S11 to S16. The computer only needs to have the function of controlling the operation of the first projector 10-1, and is not limited to the processing device 12. For example, it can also be an external personal computer connected to the first projector 10-1.

[0061] Specifically, first, in step S11, the setting unit 12a causes a setting image UI to be displayed, which will be described later. In the present embodiment, by controlling the driving of the image processing circuit 14 and the optical device 15 by the setting unit 12a, the setting image UI-1 shown below is projected onto the projection surface SC as the first projection image G1, thereby performing this display. Step S11 starts, for example, on the occasion of the startup of the first projector 10-1 or a specified operation on the operation device 16. Figure 4 As shown, the setting image UI-1 is projected onto the projection surface SC as the first projection image G1, thereby performing this display. Step S11 starts, for example, on the occasion of the startup of the first projector 10-1 or a specified operation on the operation device 16.

[0062] After step S11, in step S12, the setting unit 12a determines whether a selection operation of selecting one resolution from among the multiple resolutions that the first projector 10-1 can project has been accepted. This selection operation is performed using the setting image UI-2 shown below. Step S12 is repeated (if the answer in step S12 is no) until the selection operation is performed. In addition, in step S12, the terminal device 30 can also accept the selection operation. In this case, the setting image UI-2 shown below can be displayed on the liquid crystal display of the terminal device 30 or projected from the first projector 10-1. Figure 5 As shown, the setting image UI-2 is projected onto the projection surface SC as the first projection image G1, thereby performing this display. Step S11 starts, for example, on the occasion of the startup of the first projector 10-1 or a specified operation on the operation device 16. Figure 5 As shown, the setting image UI-2 can be displayed on the liquid crystal display of the terminal device 30 or projected from the first projector 10-1.

[0063] In the case where the selection operation has been performed (if the answer in step S12 is yes), in step S13, the setting unit 12a performs an operation of determining the resolutions of the first projection image G1 and the second projection image G2 respectively based on the selection operation in step S12. Specifically, based on the selection operation in step S12, the first projector 10-1 determines the first resolution, which is the maximum resolution that it should project, and directly sends information indicating the first resolution to the second projector 10-2. Thus, the second projector 10-2 can also determine the first resolution, which is the maximum resolution that it should project. In addition, in step S13, it can also be that after temporarily sending the information indicating the first resolution from the first projector 10-1 to the terminal device 30, the information indicating the first resolution is sent from the terminal device 30 to the second projector 10-2.

[0064] After step S13, in step S14, the setting unit 12a performs the following operation, that is, it displays the following multiple options S2 for selecting one group from multiple groups of resolution and aspect ratio of the overall image GG composed of the first projection image G1 and the second projection image G2. In the present embodiment, through the control of the setting unit 12a over the driving of the image processing circuit 14 and the optical device 15, the setting image UI-5 shown below is projected onto the projection surface SC as the first projection image G1, thereby performing this display. Figure 8 shown is projected onto the projection surface SC as the first projection image G1, thereby performing this display.

[0065] After step S14, in step S15, the setting unit 12a determines whether one option S2 has been selected from the following multiple options S2. Step S15 (no in step S15) is repeated until an operation of determining the selection of one option S2 is performed.

[0066] In the case where one option S2 is selected (yes in step S15), in step S16, the setting unit 12a sets the group of resolution and aspect ratio corresponding to the selected option S2 as the resolution and aspect ratio of the overall image GG. This set content is stored in the storage device 11 as setting information D1.

[0067] The above is the process of the display method. Hereinafter, based on Figures 4 to 8 , an example of the setting image UI used in this display method will be described. In Figures 4 to 8 , the setting images UI-1 to UI-5 that change according to the progress of the display method are shown. Hereinafter, the setting images UI-1 to UI-5 may sometimes not be distinguished from each other and are referred to as the setting image UI. In addition, the setting image UI is not limited to the example shown in Figures 4 to 8 .

[0068] Figure 4 is a diagram showing an example of the setting image UI. In step S11, for example, as shown in Figure 4 , the setting image UI-1 is displayed.

[0069] The setting image UI 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 setting image UI changes according to this operation.

[0070] The setting image UI-1 has labels T-1 to T-7, area Ra, and area Rb.

[0071] The labels T-1 to T-7 can be selectively displayed by operating the operating device 16. The label T-1 is for displaying settings related to image quality. The label T-2 is for displaying settings related to video. The label T-3 is for basic settings. The label T-4 is for extended settings. The label T-5 is for displaying settings related to the network. The label T-6 is for displaying settings related to various information. The label T-7 is for initializing settings.

[0072] Among the labels T-1 to T-7, the label T-4 is operated when setting the resolution and aspect ratio of the overall image GG. In addition, the displays other than the label T-4 among the labels T-1 to T-7 are used as needed and can also be omitted.

[0073] When the label T-4 is selected, the display area Ra is first shown. The area Ra has a button group BG1 and a button B2. The button group BG1 is for displaying the settings to be executed first in the extended settings and includes the button B1. The button B1 is for accepting an operation to change the content of the setting image UI to the content for setting the resolution of the first projector 10-1, i.e., the screen type. The button B2 is for accepting an operation to return the content of the setting image UI to the state before the previous operation.

[0074] The area Rb is for displaying an explanation of the operation method of the operating device 16 for the setting image UI.

[0075] Figure 5 It is a diagram for explaining the selection operation for the setting image UI. In Figure 4 the shown setting image UI-1, when the button B1 is operated, in step S12, as Figure 5 shown, the setting image UI-2 is displayed.

[0076] The setting image UI-2 is the same as the setting image UI-1 except that it has an area Rc instead of the labels T-1 to T-7 and the area Ra of the setting image UI-1, and has the area Rb and the area Rc.

[0077] The area Rc is for accepting a selection operation to select one resolution from among the multiple resolutions that the first projector 10-1 can project. The area Rc includes multiple options S1 and a button B2.

[0078] The multiple options S1 correspond one-to-one to the multiple resolutions that the first projector 10-1 can project and can be selectively selected by operating the operating device 16. In Figure 5 the shown example, the multiple options S1 correspond to the resolutions corresponding to the aspect ratios of 4:3, 16:6, 16:9, 16:10, and 21:9.

[0079] Each option S1 is an option for specifying how many pixels are to be used in the light modulation element of the first projector 10-1, that is, an option for specifying the resolution. Therefore, in the present embodiment, although the aspect ratio is displayed as each option S1 in the region Rc, each aspect ratio has been previously associated with the resolution in the third direction (first direction DR1) and the fourth direction (second direction DR2). That is, a group 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 2880 px × 2160 px. Here, px is a unit representing the number of pixels or the 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, the user can set the maximum resolution of the first projection image G1 that the first projector 10-1 can project to 2880 px in the first direction DR1 and 2160 px in the second direction DR2 by selecting, for example, "4:3" among the multiple options S1.

[0080] In addition, the above-mentioned resolution of 2880 px × 2160 px is an example of the first resolution. The first resolution includes the first resolution in the first direction DR1 (e.g., 2880 px) and the first resolution in the second direction DR2 (e.g., 2160 px). The first resolution in the first direction DR1 is an example of the number of pixels Wa in the horizontal direction of the light 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 light modulator 15b described later. In addition, the number of options S1 displayed, the display method, the content of the group of the corresponding resolutions and aspect ratios, etc. are not limited to Figure 5 the example shown, but are arbitrary.

[0081] When one option S1 among the multiple options S1 is selected, in the above-mentioned step S12, it is determined that a selection operation has been performed (Yes in step S12).

[0082] Figure 6 It is a diagram for explaining the setting image UI-3 after setting the resolution. In Figure 5 In the shown setting image UI-2, after a selection operation is performed, if the operation button B2 is operated, during the period from step S12 to step S14, as Figure 6 shown, the setting image UI-3 is displayed.

[0083] The setting image UI-3 is the same as the setting image UI-1 except that it has a region Rd instead of the region Ra of the setting image UI-1, and has labels T-1 to T-7, a region Rb, and a region Rd.

[0084] The area Rd is for the display of settings for multi-projection. The area Rd includes a plurality of button groups BG2 and a button B2. The button group BG2 is for the display of settings to be executed after the resolution setting of the first projector 10-1 in the extended settings, and includes a button B3. The button B3 is for the display of accepting an operation to change the content of the setting image UI to the content for executing the settings related to the overall image GG.

[0085] Figure 7 It is a diagram for explaining the settings of the group of the resolution and aspect ratio of the overall image GG. In Figure 6 the shown setting image UI-3, if the button B3 is operated, during the period from step S12 to step S14, as Figure 7 shown, the setting image UI-4 is displayed.

[0086] The setting image UI-4 is the same as the setting image UI-3 except that it has an area Re instead of the area Rd of the setting image UI-3, and has labels T-1 to T-7, an area Rb, and an area Re.

[0087] The area Re is for the display of settings related to the overall image GG. The area Re includes a plurality of button groups BG3 and a button B2. The button group BG3 is for the display of various settings related to the overall image GG, and includes a button B4. The button B4 is for the display of accepting an operation to change the content of the setting image UI to the content for setting the resolution and aspect ratio of the overall image GG.

[0088] Figure 8 It is a diagram showing a display example of a plurality of options S2 of the group of the resolution and aspect ratio of the overall image GG. In Figure 7 the shown setting image UI-4, when the button B4 is operated, in step S14, as Figure 8 shown, the setting image UI-5 is displayed. In Figure 8 it, the setting image UI-5 in the case where the resolution (aspect ratio) 3840×1644 (21:9) is selected in step S12 is shown. In addition, 3840×1644 means 3840px×1644px.

[0089] The setting image UI-5 is the same as the setting image UI-1 except that it has an area Rf instead of the labels T-1 to T-7 and the area Ra of the setting image UI-1, and has an area Rb and an area Rf.

[0090] The area Rf is for the display of accepting an operation to select one group from a plurality of groups of the resolution and aspect ratio of the overall image GG. The area Rf includes a plurality of options S2 and a button B2.

[0091] A plurality of options S2 correspond one-to-one with a plurality of groups of the resolution and aspect ratio of the overall image GG, and can be selectively selected by operating the operating device 16. In Figure 8 the example shown, the plurality of options S2 correspond to

[0092] the group with an aspect ratio of 21:9 and a resolution (EDID) of 3440×1440,

[0093] the group with an aspect ratio of 21:9 and a resolution (EDID) of 2560×1080,

[0094] the group with an aspect ratio of 16:6 and a resolution (EDID) of 2880×1080,

[0095] the group with an aspect ratio of 16:6 and a resolution (EDID) of 1920×720,

[0096] the group with an aspect ratio of 3:1 and a resolution (EDID) of 3240×1080,

[0097] the group with an aspect ratio of 32:10 and a resolution (EDID) of 3456×1080,

[0098] the group with an aspect ratio of 21:9 and a resolution (EDID) of 3200×900.

[0099] In addition, the number of options S2 displayed, the display method, the content of the group of corresponding resolution and aspect ratio, etc. are not limited to Figure 8 the example shown, but are arbitrary. EDID represents Extended Display Identification Data. That is, in the present embodiment, EDID includes the resolution. In addition, the above resolution 3440×1440 is an example of the second resolution, and the unit is px. The second resolution includes the second resolution in the first direction DR1 (for example, 3440 px) and the second resolution in the second direction DR2 (for example, 1440 px). The second resolution in the first direction DR1 is an example of the number of pixels W of the overall image GG described later, and the second resolution in the second direction DR2 is an example of the number of pixels H of the overall image GG described later.

[0100] When one option S2 among the plurality of options S2 is selected by operating the operating device 16, in the above step S15, it is determined that one option S2 is selected (Yes in step S15). In addition, in step S16, setting information D1 representing the group of the resolution and aspect ratio corresponding to the selected option S2 is generated. Thus, the group of the resolution and aspect ratio shown in the setting information D1 is set as the resolution and aspect ratio of the overall image GG.

[0101] In such an image UI-5 for the setting, the user needs to visually confirm multiple options S2 and then select one option S2 from the multiple options S2 through the operation of the operation device 16. Therefore, from the perspective of improving usability, in step S14, the setting unit 12a makes the display modes of the multiple options S2 different according to the conditions of at least one parameter that defines the overall image.

[0102] That is, in step S14, the setting unit 12a makes the display mode of option S2-a among the multiple options S2 different from the display mode of option S2-b. Option S2-a is an option S2 corresponding to a group of resolution and aspect ratio that satisfies the following condition, which is the condition of at least one parameter that defines the overall image, and option S2-b is another option S2. Therefore, it is possible to easily and intuitively grasp which resolution of the overall image GG satisfies the condition. Thus, usability can be improved.

[0103] Preferably, the operation of selecting the option S2 corresponding to the group of resolution and aspect ratio that does not satisfy the condition among the multiple options S2 is invalidated. Thereby, it is possible to prevent the overall image GG that does not have the optimal repetition width, i.e., the number of pixels X, from being misselected by the user as described later.

[0104] In Figure 8 the example shown, option S2-a represents a selectable display mode, while option S2-b represents a non-selectable display mode. In addition, the display modes of options S2-a and S2-b are not limited to Figure 8 the example shown. For example, it may also be a way that makes the display of option S2-b grayed out or the like, making it less obvious compared to the display of option S2-a. Also, option S2-b corresponding to the group of resolution and aspect ratio that does not satisfy this condition may be selectable. However, in this case, it must be possible to select option S2-a corresponding to the group of resolution and aspect ratio that satisfies this condition. Additionally, in this case, preferably, option S2-b is a display mode indicating precautions related to the display mode of the overall image GG in the case of selection.

[0105] Figure 9This is a diagram for explaining the relationship between the resolution and aspect ratio of the overall image GG and those of the modulators 15b-1 and 15b-2. When the number of pixels of the overall image GG in the first direction DR1 is W, the number of pixels in the longitudinal direction (the fourth direction) of the light modulator 15b is Ha, the number of pixels in the longitudinal direction (the third direction) of the resolution corresponding to option S2 is Hb, and the number of pixels in the lateral direction of the resolution corresponding to option S2 is Wb, the number of pixels W is represented by W = Ha × (Wb / Hb). Wb / Hb corresponds to the aspect ratio of the overall image GG that the user wants to construct. In addition, the number of pixels Ha can also be said to be the number of pixels in the second direction DR2 at the resolution that the projector 10 can project. The number of pixels Ha is an example of the first resolution in the 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 the second resolution of the overall image in the first direction.

[0106] In addition, when the number of pixels of the overlapping region R in the first direction DR1 is set to X and the number of pixels in the lateral direction of the light modulator 15b is set to Wa, the number of pixels X is represented by X = (Wa + Wa) - W = (Wa × 2) - W. The number of pixels of 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 in the light modulator 15b. That is, the number of pixels of 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 overall image GG. In addition, the number of pixels Wa can also be said to be the number of pixels in the first direction DR1 at the resolution that the projector 10 can project.

[0107] Here, when the ratio of the number of pixels X to the number of pixels Wa, that is, the first ratio X / Wa, is too small, the number of pixels X cannot be ensured sufficiently. For example, at some resolutions of the imaging device 17, it is difficult to use the imaging result of the imaging device 17 to correct the image of the overlapping region R. On the other hand, when the first ratio X / Wa is too large, it is difficult to obtain the advantage of constructing the overall image GG using the first projected image G1 and the second projected image G2. The first ratio X / Wa indicates how many pixels X the overlapping region R occupies in the number of pixels Wa of the first projected image G1 in the first direction DR1.

[0108] Therefore, in step S14, the first ratio X / Wa is used as a parameter for the determination condition for setting option S2 to option S2-a. That is, the parameter used in step S14 is the ratio of the number of pixels X of the overlapping region R in the first direction DR1 to the number of pixels Wa of the first projected image G1 in the first direction DR1, which is the first ratio X / Wa. The first direction DR1 is the direction in which the first projected image G1 and the second projected image G2 are arranged. In addition, the condition in step S14 is that the first ratio X / Wa deviates from the first range. Thus, it is possible to easily and simply grasp which overall image GG does not have the optimal overlapping width. Here, according to the respective 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, the number of pixels X of the overlapping region R in the first direction DR1 is calculated as shown in the above formula.

[0109] Here, the lower limit of the first range is preferably 12.5%. Thus, the number of pixels X can be sufficiently ensured. The lower limit of the first range is an example of a first value greater than zero. In addition, 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. That is, the first ratio X / Wa deviating from the first range means that the first ratio X / Wa is less than the lower limit of the first range or greater than the upper limit of the first range. Thus, the advantage of constructing the overall image GG using the first projected image G1 and the second projected image G2 can be easily obtained.

[0110] Figure 10 and Figure 11 are examples of groups for explaining the resolution and aspect ratio of the overall image GG, respectively.

[0111] In Figure 10 shows the relationship between the resolution and aspect ratio of the overall image GG, 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). In Figure 11 shows the relationship between the resolution and aspect ratio of the overall image GG, 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).

[0112] In Figure 10 and Figure 11In the example shown, among the multiple groups of the resolution and aspect ratio of the overall image GG, there is a group in which the first ratio X / Wa exceeds 70%. Therefore, when 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 group of the resolution and aspect ratio of the overall image GG where the first ratio X / Wa exceeds 70% becomes option S2-b.

[0113] Figure 12 FIG. is a diagram showing another display example of the multiple options S2 of the group of the resolution and aspect ratio of the overall image GG. In Figure 12 it shows the setting image UI-5 when the resolution (aspect ratio) 3840×2160 (16:9) is selected in step S12.

[0114] When the number of pixels of the overall image GG in the second direction DR2 is H, if the overlapping region R is ensured, when the number of pixels H is less than the number of pixels Ha, that is, when the ratio of the number of pixels H to the number of pixels Ha, namely the second ratio H / Ha, is 0 or more and less than 1, upper and lower black bands, which are regions not used in drawing, are generated in the upper and lower parts of the first projection image G1 and the second projection image G2.

[0115] For example, in step S13, it is determined that the number of pixels Wa = 3456px and the number of pixels Ha = 2160px in the first projector 10-1 and the second projector 10-2 respectively. And, for example, a group with an aspect ratio of 32:10 and a resolution (EDID) of 3456×1080 is selected as option S2. At this time, the number of pixels W of the overall image GG is Ha×(Wb / Hb) = 2160×(3456 / 1080) = 6912px. This value is exactly twice the number of pixels Wa. In this state, even if it is assumed that an overall image GG with an aspect ratio of 32:10 and a resolution (EDID) of 3456×1080 is constructed, the number of pixels X of the overlapping region R is zero, that is, the first ratio X / Wa = 0, which does not meet the preferred lower limit of 12.5%.

[0116] Therefore, in the present embodiment, for example, the number of pixels W of the actual overall image GG is corrected in such a way that 12.5% of 3456 px, i.e., 432 px, is ensured as the number of pixels X of the overlapping region R. Specifically, 6480 px obtained by subtracting 432 px from 6912 px is adopted as the number of pixels W of the actual overall image GG. At this time, since the user hopes to finally construct an overall image GG with an aspect ratio of 32:10, based on the number of pixels W of the overall image GG being 6480 px, the number of pixels H of the overall image GG is calculated as 6480 px (W) × (10 / 32) = 2025 px. This 2025 px corresponds to H in the second ratio H / Ha described later. On the other hand, as described above, since the number of pixels Ha = 2160 px is determined in step S13, the first projector 10-1 and the second projector 10-2 can use the originally maximum number of pixels Ha = 2160 px. However, as shown by the above calculation, in fact, in order to construct an overall image GG with an aspect ratio of 32:10, the number of pixels H of the overall image GG should be set to 2025 px. Therefore, in the second direction DR2, the number of pixels H is 135 px less than the number of pixels Ha, which is obtained by subtracting 2025 px from 2160 px. Therefore, in the second direction DR2, black bands corresponding to the difference between the number of pixels H and the number of pixels Ha are generated in the first projection image G1 and the second projection image G2. In this case, when the second ratio H / Ha is defined, the second ratio H / Ha is calculated as 2025 / 2160 = 0.9375. That is, the second ratio H / Ha can be said to be an index for determining whether black bands are generated in the first projection image G1 and the second projection image G2 in the second direction DR2. In addition, when no black bands are generated in the first projection image G1 and the second projection image G2 in the second direction DR2, the second ratio H / Ha is greater than 1. That is, when the number of pixels H is greater than the number of pixels Ha, no black bands are generated in the first projection image G1 and the second projection image G2. When the number of pixels H is greater than the number of pixels Ha, several pixels among the pixels constituting the number of pixels H are removed at intervals so as to converge within the range of the number of pixels Ha.

[0117] Therefore, in step S14, the second ratio H / Ha is used as a parameter for the condition for determining to set option S2 to 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 overall image GG in the second direction DR2 to the number of pixels Ha of the first projected image G1 in the second direction DR2. The second direction DR2 is a direction perpendicular to the first direction DR1 in which the first projected image G1 and the second projected image G2 are arranged. The number of pixels H of the overall image GG in the second direction DR2 is an example of the second resolution of the overall image GG in the second direction. The number of pixels H of the overall image GG in the second direction DR2 is calculated based on the number of pixels W of the overall image GG in the first direction DR1 and the aspect ratio of the overall image GG. In addition, the condition in step S14 is that the second ratio H / Ha is less than 1. Thus, it is possible to easily identify which overall image GG has black bands generated in the upper and lower parts. Furthermore, since the second ratio H / Ha is a positive number, the condition can also be set to be 0 or more and less than 1 for the second ratio H / Ha.

[0118] In Figure 12 the example shown, in step S14, the setting unit 12a makes the display mode of option S2-a among the multiple options S2 different from the display mode of option S2-d. Option S2-a is an option S2 corresponding to a set of resolution and aspect ratio that satisfies the following condition, which is a condition of at least one parameter for the overall image. Option S2-d is the other option S2.

[0119] Option S2-d represents a display mode in which, although it can be selected, regions that are not used in the drawing, namely upper and lower black bands, will be generated in the upper and lower parts of the first projected image G1 and the second projected image G2. In Figure 12 the example shown, the display "!" is added to option S2-d, and an explanation of the display "!" is shown within the setting image UI. In addition, the display mode of option S2-d is not limited to Figure 12 the example shown. For example, it can also be a mode that is less obvious compared to the display of option S2-a by being grayed out or the like. In addition, option S2-d can also be made non-selectable in the same way as the above-mentioned option S2-b.

[0120] The parameter used in step S14 may also include the above-mentioned first ratio X / Wa and second ratio H / Ha. In this case, the condition in step S14 is that the first ratio X / Wa deviates from the first range, and the second ratio H / Ha is 0 or more and less than 1. Thus, it is possible to easily and simply identify which overall image GG does not have the width of the optimal overlapping region R, that is, the repetition width, and generates upper and lower black bands.

[0121] Figures 13 to 15An example of a group for explaining the resolution and aspect ratio of the overall image GG respectively.

[0122] In Figure 13 it shows the relationship between the resolution and aspect ratio of the overall image GG, the number of pixels W and X, and the first ratio X / Wa when the resolution (aspect ratio) selected in step S12 is 3840×2160 (16:9). In Figure 14 it shows the relationship between the resolution and aspect ratio of the overall image GG, the number of pixels W and X, and the first ratio X / Wa when the resolution (aspect ratio) selected in step S12 is 3456×2160 (16:10). In Figure 15 it shows the relationship between the resolution and aspect ratio of the overall image GG, the number of pixels W and X, and the first ratio X / Wa when the resolution (aspect ratio) selected in step S12 is 2880×2160 (4:3).

[0123] In Figure 13 and Figure 15 In the examples shown, among the multiple groups of the resolution and aspect ratio of the overall image GG, there is a group where the second ratio H / Ha is 1 or more. Therefore, when the resolution (aspect ratio) selected in step S12 is 3840×2160 (16:9), 3456×2160 (16:10), or 2880×2160 (4:3), in step S14, the option S2 corresponding to the group of the resolution and aspect ratio of the overall image GG where the second ratio H / Ha is 1 or more becomes option S2-d.

[0124] 2. Second Embodiment

[0125] Hereinafter, a second embodiment of the present disclosure will be described. In the following exemplified manner, for elements having the same functions and operations as those in the first embodiment, the reference numerals used in the description of the first embodiment are used and their detailed descriptions are appropriately omitted.

[0126] Figure 16 is a block diagram of the terminal device 30A used in the display method according to the second embodiment. The terminal device 30A is an example of a "computer" and is configured in the same manner as the terminal device 30 in the first embodiment except for executing the program PR2. In addition, in this embodiment, the program PR1 of the first embodiment may also be omitted.

[0127] As Figure 16 shown, 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. They are connected in a manner that enables communication with each other.

[0128] The storage device 31 is a storage device that stores the programs executed by the processing device 32 and the 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. In addition, part or all of the storage device 31 may be provided in an external storage device or a server of the terminal device 30A.

[0129] The program PR2, the setting information D1, and the resolution information D2 are stored in the storage device 31.

[0130] The program PR2 is a program for executing the display method described in detail later. The resolution information D2 includes one or both of the first information indicating the maximum number of resolutions that the first projector 10-1 can project and the second information indicating the maximum number of resolutions that the second projector 10-2 can project. Figure 17

[0131] The processing device 32 is a processing device having a function of controlling each part of the terminal device 30A and a function of processing various data. The processing device 32 is configured to include, for example, a processor such as a CPU. In addition, the processing device 32 may be composed of a single processor or multiple processors. In addition, part or all of the functions of the processing device 32 may be implemented by hardware such as a DSP, an ASIC, a PLD, or an FPGA.

[0132] 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, a USB, or an HDMI, a wireless communication device such as an LPWA, a wireless LAN including Wi-Fi, or Bluetooth. "HDMI", "Wi-Fi", and "Bluetooth" are registered trademarks, respectively.

[0133] 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.

[0134] The input device 35 is a device that accepts operations from a user. For example, the input device 35 has an indicating device such as a touchpad, a touch panel, or a mouse. Here, when the input device 35 has a touch panel, it may also serve as the display device 34. In addition, the input device 35 may be provided outside the terminal device 30A. In addition, the input device 35 may have other input devices such as a keyboard.

[0135] ​In the above-described terminal device 30A, the processing device 32 functions as the setting unit 32a by executing the program PR2 stored in the storage device 31. Thus, the processing device 32 includes the setting unit 32a.

[0136] The setting unit 32a sets the resolution and aspect ratio of the overall image GG. Specifically, the setting unit 32a obtains the resolution information D2 based on one or both of the first information obtained from the first projector 10-1 and the second information obtained from the second projector 10-2, and based on the resolution information D2, displays the setting image UI required for setting the resolution and aspect ratio of the overall image GG. In addition, the setting unit 32a performs the processing required for setting the resolution and aspect ratio of the overall image GG based on the operation of the input device 35 on the setting image UI.

[0137] Figure 17 It is a flowchart showing the process of the display method according to the second embodiment. This display method uses the above-described terminal device 30A and is performed by the processing device 32 executing the program PR2. As Figure 17 shown, this display method includes steps S21 to S25. That is, the terminal device 30A executes steps S21 to S25. In addition, the program PR2 causes the terminal device 30A, which is an example of a computer, to execute steps S21 to S25.

[0138] Specifically, first, in step S21, the setting unit 32a causes the setting image UI to be displayed. In the present embodiment, by controlling the driving of the display device 34 by the setting unit 32a, the above-described Figure 4 shown setting image UI-1 is displayed on the display device 34, thereby performing this display. Step S21 starts, for example, on the occasion of a prescribed operation of the input device 35.

[0139] After step S21, in step S22, the setting unit 32a obtains the resolution that can be projected by one or both of the first projector 10-1 and the second projector 10-2. Thus, the resolution information D2 is obtained. 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.

[0140] Thus, in step S22, the setting unit 32a obtains one or both of the first information indicating the maximum number of resolutions that the first projector 10-1 can project and the second information indicating the maximum number of resolutions that the second projector 10-2 can project.

[0141] After step S22, in step S23, the setting unit 32a executes the display of a plurality of options S2. In the present embodiment, by controlling the driving of the display device 34 by the setting unit 32a, the setting image UI-5 shown in Figure 8 is displayed on the display device 34, thereby performing this display.

[0142] Thus, in step S23, the setting unit 32a displays a plurality of options S2 for selecting one group from a plurality of groups of the 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.

[0143] Here, similar to step S14 of the first embodiment, in step S23, the display mode of the option corresponding to the group of the resolution and aspect ratio of the overall image GG among the plurality of options S2 that can be displayed by the first projector 10-1 and the second projector 10-2 is different from the display modes of the other options S2.

[0144] After step S23, in step S24, similar to step S15 described above, the setting unit 32a determines whether one option S2 has been selected from the plurality of options S2. Step S24 (No in step S24) is repeated until an operation for determining the selection of one option S2 is performed.

[0145] When one option S2 is selected (Yes in step S24), in step S25, the setting unit 32a sets the group of the resolution and aspect ratio corresponding to the selected option S2 as the resolution and aspect ratio of the overall image GG. Thus, it is stored in the storage device 31 as the setting information D1. Moreover, the setting unit 32a sends 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.

[0146] According to the above second embodiment, also by making the display mode of the option S2 corresponding to the group of the resolution and aspect ratio of the overall image GG that can be displayed by the first projector 10-1 and the second projector 10-2 different from the display modes of the other options S2, it is possible to easily and intuitively grasp which resolution of the overall image GG satisfies the conditions. Thus, usability can be improved.

[0147] 3. Modification

[0148] Each of the above-exemplified modes can be deformed in various ways. The following are specific deformation modes that can be applied to each of the above modes. Two or more modes arbitrarily selected from the following exemplifications can be appropriately combined within a non-contradictory range.

[0149] 3-1. Variant Example 1

[0150] In the above-described embodiment, the manner in which the first projection image G1 and the second projection image G2 are arranged horizontally is illustrated, but it is not limited to this manner. For example, the first projection image G1 and the second projection image G2 may also be arranged vertically. That is, the first direction DR1 is not limited to the horizontal direction and may be, for example, the vertical direction. In addition, the first direction DR1 is not limited to the manner that coincides with the horizontal direction of the first projection image G1 or the second projection image G2. For example, it may also coincide with the vertical direction of the first projection image G1 or the second projection image G2.

[0151] 3-2. Variant Example 2

[0152] In the above-described embodiment, the resolution and aspect ratio of the overall image GG are displayed in each option S2, but it is not limited to this. Specifically, as long as the first projector 10-1 and the second projector 10-2 can recognize the resolution and aspect ratio of the overall image GG to be projected according to the situation where the option S2 has been selected, either the resolution or the aspect ratio of the overall image GG may be displayed in each option S2. For example, it may also be that only the aspect ratio is displayed in each option S2, and the groups of aspect ratio 21:9 and resolution (EDID) 3440×1440, and aspect ratio 21:9 and resolution (EDID) 2560×1080 are respectively displayed as aspect ratio 21:9 (large resolution) and aspect ratio 21:9 (small resolution). As another example, only the resolution of the overall image GG, that is, the EDID, may be displayed in each option S2.

[0153] 3-3. Variant Example 3

[0154] In addition, when at least any one of the computers included in the terminal device 30 (30A), the first projector 10-1, and the second projector 10-2 is used to implement at least one of the programs PR1 and PR2, it is also possible to configure a program that causes these computers to execute in a manner that can be read by a computer and is a non-transitory recording medium.
