[0039] Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

[0040] (Implementation Method 1)

[0041] <Brief Structure of Projection Device 10 for Setting Assist Object Based on Embodiment 1>

[0042] Figure 1 This is a schematic diagram showing the general structure of the projection device 10 for setting up an object based on the setting up assistance device of Embodiment 1.

[0043] The setup assistance device in this embodiment can be used to assist in setting up the projection device 10. The projection device 10 includes a projection unit 1, a control device 4, and an operation receiving unit 2. The projection unit 1 is, for example, a liquid crystal projector or a projector using LCOS (Liquid Crystal On Silicon). In the following description, the projection unit 1 will be described as a liquid crystal projector.

[0044] The control device 4 is a control device that controls the projection of the projection device 10. The control device 4 includes a control unit composed of various processors, a communication interface (not shown) for communicating with each unit, and a memory 4a such as a hard disk, SSD (Solid State Drive) or ROM (Read Only Memory), and centrally controls the projection unit 1.

[0045] The various processors that serve as the control unit of the control device 4 include general-purpose processors that execute programs to perform various processes, such as CPUs (Central Processing Units), FPGAs (Field Programmable Gate Arrays), and other processors whose circuit structure can be changed after manufacturing, such as Programmable Logic Devices (PLDs), or ASICs (Application Specific Integrated Circuits), which have circuit structures specifically designed to perform specific processes, such as dedicated circuits.

[0046] More specifically, these various processors are structured as circuits composed of semiconductor elements and other circuit elements. The control unit of the control device 4 can be composed of one of the various processors, or it can be composed of a combination of two or more processors of the same or different types (e.g., a combination of multiple FPGAs or a combination of a CPU and an FPGA).

[0047] The operation receiving unit 2 receives various operations from the user and detects instructions from the user. The operation receiving unit 2 may be a button, key, joystick, or other similar device installed on the control device 4, or it may be a receiving unit that receives signals from a remote controller that remotely operates the control device 4.

[0048] The object to be projected 6 is an object such as a screen or wall that has a projection surface through which the projected image is displayed by the projection unit 1. Figure 1 In the example shown, regarding the projected object 6, the projection surface of the projected object 6 is a rectangular plane. Figure 1 The top, bottom, left, and right sides of the projected object 6 are set to the actual top, bottom, left, and right sides of the projected object 6.

[0049] The projection range 11, illustrated by a single-dot-dash line, represents the area of ​​the object 6 illuminated by the projection unit 1. Figure 1 In the example described, the projection range 11 is rectangular. The projection range 11 is a part or all of the projectable range that can be projected through the projection unit 1.

[0050] Furthermore, the projection unit 1, the control device 4, and the operation receiving unit 2 are implemented, for example, by a single device (see, for example, reference). Figure 3 , Figure 4 Alternatively, the projection unit 1, the control device 4, and the operation receiving unit 2 may be separately provided devices that cooperate by communicating with each other.

[0051] < Figure 1 The internal structure of the projection section 1 shown >

[0052] Figure 2 It means Figure 1 A schematic diagram of an example of the internal structure of the projection section 1 shown.

[0053] like Figure 2 As shown, the projection unit 1 includes a light source 21, a light modulation unit 22, a projection optical system 23, and a control circuit 24.

[0054] The light source 21 includes light-emitting elements such as lasers or LEDs (Light Emitting Diodes), for example, emitting white light.

[0055] The light modulation unit 22 consists of three liquid crystal panels. These liquid crystal panels modulate the light emitted from the light source 21, which has been separated into red, blue, and green colors by a color separation mechanism (not shown), according to image information, to emit images of each color. Red, blue, and green filters can be mounted on the three liquid crystal panels respectively, and each liquid crystal panel can modulate the white light emitted from the light source 21 to emit images of each color.

[0056] The projection optical system 23 receives light from the light source 21 and the light modulation unit 22, and is composed of, for example, a relay optical system including at least one lens. The light passing through the projection optical system 23 is projected onto the object 6 to be projected.

[0057] The area illuminated by the light from the entire range of the light modulation unit 22 in the projected object 6 becomes the projectable range that can be projected by the projection unit 1. Within this projectable range, the area illuminated by the light actually transmitted from the light modulation unit 22 becomes the projection range 11. For example, by controlling the size, position, and shape of the area through which light is transmitted in the light modulation unit 22, the size, position, and shape of the projection range 11 can be changed within the projectable range.

[0058] The control circuit 24 controls the light source 21, the light modulation unit 22, and the projection optical system 23 based on the display data input from the control device 4, thereby projecting an image based on the display data onto the object 6. The display data input to the control circuit 24 consists of three types: red display data, blue display data, and green display data.

[0059] Furthermore, the control circuit 24 modifies the projection optical system 23 according to the command input from the control device 4, thereby adjusting the projection range 11 of the projection unit 1 (see reference). Figure 1 The projection range 11 of the projection unit 1 can be expanded or reduced. Furthermore, the control device 4 can change the projection optical system 23 according to the operation received from the user by the operation receiving unit 2, thereby moving the projection range 11 of the projection unit 1.

[0060] Furthermore, the projection device 10 has a displacement mechanism that maintains the image ring of the projection optical system 23 while mechanically or optically moving the projection area 11. The image ring of the projection optical system 23 is the area where the projection light incident on the projection optical system 23 passes through the projection optical system 23 appropriately from points such as light intensity reduction, color separation, and peripheral curvature.

[0061] The displacement mechanism is realized by at least one of an optical system displacement mechanism for optical system displacement and an electronic displacement mechanism for electronic displacement.

[0062] The optical system displacement mechanism is, for example, a mechanism that moves the projection optical system 23 in a direction perpendicular to the optical axis (e.g., reference...). Figure 3 , Figure 4 Alternatively, a mechanism can be used to move the movable light modulation unit 22 in a direction perpendicular to the optical axis instead of moving the projection optical system 23. Furthermore, the optical system displacement mechanism can combine the movement of the projection optical system 23 with the movement of the light modulation unit 22.

[0063] The electronic displacement mechanism is a mechanism that simulates the displacement of the projection range 11 by changing the light transmission range in the light modulation unit 22.

[0064] Furthermore, the projection device 10 may include a projection direction changing mechanism that moves the projection range 11 together with the image ring of the projection optical system 23. The projection direction changing mechanism is a mechanism that changes the projection direction of the projection unit 1 by mechanically rotating it to change its orientation (for example, see reference...). Figure 3 , Figure 4 ).

[0065] <Mechanical Structure of Projection Device 10>

[0066] Figure 3 This is a schematic diagram showing the external structure of the projection device 10. Figure 4 yes Figure 3 A cross-sectional schematic diagram of the optical unit 106 of the projection device 10 shown. Figure 4 Indicates along from Figure 3 A cross-section of the surface formed by the light path emitted from the main body 101 shown.

[0067] like Figure 3As shown, the projection device 10 includes a main body 101 and an optical unit 106 protruding from the main body 101. Figure 3 In the structure shown, the operation receiving unit 2, the control device 4, the light source 21, the light modulation unit 22, and the control circuit 24 in the projection unit 1 are disposed in the main body 101. The projection optical system 23 in the projection unit 1 is disposed in the optical unit 106.

[0068] The optical unit 106 includes: a first component 102 supported by the main body 101; and a second component 103 supported by the first component 102.

[0069] Furthermore, the first component 102 and the second component 103 can be integrally formed. The optical unit 106 can be configured to be freely mounted and detached from the main body 101 (in other words, to be interchangeable).

[0070] The main body 101 has an opening 15a (see reference) formed in the portion connected to the optical unit 106 for allowing light to pass through. Figure 4 ) frame 15 (reference) Figure 4 ).

[0071] like Figure 3 As shown, a light source 21 and a light modulation unit 12 are disposed inside the frame 15 of the main body 101. The light modulation unit 12 includes a light modulation section 22 (see reference) that spatially modulates the light emitted from the light source 21 according to the input image data to generate an image. Figure 2 ).

[0072] Light emitted from the light source 21 is incident on the light modulation section 22 of the light modulation unit 12 and is spatially modulated by the light modulation section 22 before being emitted.

[0073] like Figure 4 As shown, an image formed by light spatially modulated by the light modulation unit 12 is incident on the optical unit 106 through the opening 15a of the frame 15 and projected onto the object 6, which is the object of projection, so that the observer can visually recognize the image G1.

[0074] like Figure 4 As shown, the optical unit 106 includes: a first component 102 having a hollow portion 2A connected to the interior of the main body 101; a second component 103 having a hollow portion 3A connected to the hollow portion 2A; a first optical system 121 and a reflective component 122 disposed in the hollow portion 2A; a second optical system 31, a reflective component 32, a third optical system 33, and a lens 34 disposed in the hollow portion 3A; a displacement mechanism 105; and a projection direction changing mechanism 104.

[0075] The first component 102 is, for example, a rectangular component in cross-section, with openings 2a and 2b formed on mutually perpendicular surfaces. The first component 102 is supported by the main body 101 with opening 2a positioned opposite to opening 15a of the main body 101. Light emitted from the light modulation section 22 of the light modulation unit 12 of the main body 101 enters the hollow portion 2A of the first component 102 through openings 15a and 2a.

[0076] The incident direction of light from the main body 101 to the hollow part 2A is recorded as direction X1, and the direction opposite to direction X1 is recorded as direction X2. Directions X1 and X2 are collectively referred to as direction X. Furthermore, in Figure 4 In this context, the direction from the front of the paper toward the inside and the opposite direction are recorded as direction Z. Within direction Z, the direction from the front of the paper toward the inside is recorded as direction Z1, and the direction from the inside of the paper toward the front is recorded as direction Z2.

[0077] Furthermore, the direction perpendicular to both direction X and direction Z is recorded as direction Y. Within direction Y, [the following will be included / distributed]. Figure 4 The direction upwards is recorded as direction Y1, and will be... Figure 4 The direction downwards is recorded as direction Y2. Figure 4 In the example, the projection device 10 is configured such that direction Y2 is the vertical direction.

[0078] Figure 2 The projection optical system 23 shown consists of a first optical system 121, a reflective component 122, a second optical system 31, a reflective component 32, a third optical system 33, and a lens 34. Figure 4 The optical axis K of the projection optical system 23 is shown. A first optical system 121, a reflective component 122, a second optical system 31, a reflective component 32, a third optical system 33, and a lens 34 are arranged sequentially along the optical axis K from the light modulation unit 22 side.

[0079] The first optical system 121 includes at least one lens that guides light incident from the main body 101 onto the first component 102 and traveling in the direction X1 to the reflective component 122.

[0080] The reflecting member 122 reflects light incident from the first optical system 121 in the direction Y1. The reflecting member 122 is, for example, a mirror. In the first component 102, an opening 2b is formed in the optical path of the light reflected by the reflecting member 122, and the reflected light travels through the opening 2b toward the hollow portion 3A of the second component 103.

[0081] The second component 103 has a generally T-shaped cross-section and an opening 3a is formed opposite to the opening 2b of the first component 102. Light from the main body 101 passing through the opening 2b of the first component 102 enters the hollow portion 3A of the second component 103 through the opening 3a. Furthermore, the cross-sectional shape of either the first component 102 or the second component 103 is arbitrary and not limited to the above description.

[0082] The second optical system 31 includes at least one lens that guides light incident from the first component 102 to the reflective component 32.

[0083] The reflecting component 32 reflects light incident from the second optical system 31 in the direction X2 and guides it to the third optical system 33. The reflecting component 32 is, for example, a mirror.

[0084] The third optical system 33 includes at least one lens that guides light reflected by the reflecting component 32 to the lens 34.

[0085] Lens 34 is disposed at the end of the second component 103 such that it closes the opening 3c formed at the end on the X2 side. Lens 34 projects light incident from the third optical system 33 onto the object 6 to be projected.

[0086] The projection direction changing mechanism 104 is a rotating mechanism that rotatably connects the second component 103 to the first component 102. Through this projection direction changing mechanism 104, the second component 103 is configured to rotate freely about a rotation axis (specifically, the optical axis K) extending in the Y direction. Furthermore, the projection direction changing mechanism 104 is not limited to any mechanism that can rotate the optical system. Figure 4 The configuration positions are shown. Furthermore, the number of rotating mechanisms is not limited to one; multiple mechanisms can be configured.

[0087] The displacement mechanism 105 is used to move the optical axis K of the projection optical system (in other words, the optical unit 106) along a direction perpendicular to its optical axis K. Figure 4 The displacement mechanism 105 is configured to change the position of the first component 102 relative to the main body 101 in the direction Y. In addition to moving the first component 102 manually, the displacement mechanism 105 can also move the first component 102 electrically.

[0088] Figure 4 This indicates that the first component 102 has moved to its maximum extent in the direction Y1 via the displacement mechanism 105. Figure 4In the state shown, the first component 102 moves in the direction Y2 via the displacement mechanism 105, thereby changing the relative position of the center of the image formed by the light modulation unit 22 (in other words, the center of the display surface) with the optical axis K, and enabling the image G1 projected onto the object 6 to be displaced (parallel moved) in the direction Y2.

[0089] Alternatively, the displacement mechanism 105 can be a mechanism that moves the light modulation unit 22 in the Y direction instead of the optical unit 106 in the Y direction. Even in this case, the image G1 projected onto the object 6 can be moved in the Y direction.

[0090] <Setting Auxiliary Device 50 of Embodiment 1>

[0091] Figure 5 This figure illustrates an example of the setup assistance device 50 according to Embodiment 1. The setup assistance device 50 of Embodiment 1 is a tablet terminal having a touch panel 51. The touch panel 51 is a touch-operable display. For example, a user of the setup assistance device 50 brings it into a space (e.g., a room) where a projection device 10 is being set up for projection. The setup assistance device 50 displays setup assistance images via the touch panel 51 to assist in setting up the projection device 10 in that space.

[0092] <Hardware Structure of Auxiliary Device 50>

[0093] Figure 6 This diagram illustrates an example of the hardware structure of the installation assistance device 50 according to Embodiment 1. For example, such as... Figure 6 As shown, Figure 5 The setup assistance device 50 shown includes a processor 61, a memory 62, a communication interface 63, a user interface 64, and a sensor 65. The processor 61, memory 62, communication interface 63, user interface 64, and sensor 65 are connected, for example, via a bus 69.

[0094] Processor 61 is a circuit that performs signal processing, such as a CPU that manages the overall control of the auxiliary device 50. Alternatively, processor 61 can be implemented using other digital circuits such as an FPGA or a DSP (Digital Signal Processor). Furthermore, processor 61 can be implemented by combining multiple digital circuits.

[0095] The memory 62 includes, for example, main memory and auxiliary memory. The main memory is, for example, RAM (Random Access Memory). The main memory serves as the working area for the processor 61.

[0096] Auxiliary storage is, for example, non-volatile memory such as a hard disk or flash memory. The auxiliary storage contains various programs that enable the setup auxiliary device 50 to run. The programs stored in the auxiliary storage are loaded into main memory and executed by the processor 61.

[0097] Furthermore, the auxiliary storage device may include a portable storage device that can be attached to and detached from the auxiliary device 50. Portable storage devices include memory cards such as USB (Universal Serial Bus) flash drives or SD (Secure Digital) memory cards, or external hard drives.

[0098] Communication interface 63 is a communication interface for communicating with external devices that provide auxiliary equipment 50. Communication interface 63 includes at least one of a wired communication interface for wired communication and a wireless communication interface for wireless communication. Communication interface 63 is controlled by processor 61.

[0099] User interface 64 may include, for example, an input device that receives operation input from the user or an output device that outputs information to the user. The input device may be implemented, for example, via buttons (e.g., a keyboard) or a remote control. The output device may be implemented, for example, via a display or a speaker. Figure 5 In the setup assistance device 50 shown, input and output devices are implemented via a touch panel 51. The user interface 64 is controlled by a processor 61.

[0100] Sensor 65 includes a camera device with an imaging optical system and imaging element capable of capturing images, or a spatial recognition sensor capable of three-dimensionally recognizing the surrounding space of the setting auxiliary device 50, etc. Figure 5 The camera device on the back of the setting auxiliary device 50 shown.

[0101] One example of a spatial identification sensor is LIDAR (Light Detection and Ranging), which measures the time it takes for a laser to strike an object and bounce back, thereby determining the distance or direction of the object. However, spatial identification sensors are not limited to this; they can be various sensors such as radar that emits radio waves or ultrasonic sensors that emit ultrasonic waves.

[0102] <Setting assistance for projection device 10 based on setting assistance device 50 in embodiment 1>

[0103] Figures 7-10This diagram illustrates an example of setting assistance provided by the projection device 10 based on the setting assistance device 50 of Embodiment 1. The setting assistance device 50 displays a spatial image 70, for example, via a touch panel 51. The spatial image 70 is an image representing the space 71 projected by the projection device 10. Figure 7 In the example, space 71 is a room containing walls 71a, 71b and ceiling 71c. Furthermore, a clock 71d is installed on wall 71a.

[0104] The spatial image 70 is, for example, a viewfinder image (live view image) that is captured in real time by a camera device, which is a sensor 65, provided in the setting aid 50. In this case, the spatial image 70 represents in real time the wall 71a, etc., of the space 71 that actually exists behind the setting aid 50.

[0105] like Figure 8 As shown, the setting auxiliary device 50 receives input from the user regarding the projection range 81 in the space 71. For example, the user specifies the range to be set as the projection range 81 in the spatial image 70 displayed on the touch panel 51 via touch operation or the like. Figure 6 In the example shown, the user specifies the range of the rectangle in wall 71a that deviates from clock 71d as the projection range 81.

[0106] For example, the setting assist device 50 generates corresponding information about the position coordinates of the space 71, which is three-dimensionally identified by the spatial recognition sensor included in the sensor 65, and the position coordinates of the spatial image 70, which is two-dimensionally displayed on the touch panel 51. Furthermore, using this corresponding information, the setting assist device 50 converts the range specified by the user in the spatial image 70 displayed on the touch panel 51 into a projection range 81 defined by the position coordinates of the three-dimensionally identified space 71. Thus, the setting assist device 50 can receive input from the user of the projection range 81 of the projection device 10.

[0107] like Figure 9 As shown, the setting assistance device 50 calculates the setting range 91 within the space 71 where the projection device 10 can be set based on the input projection range 81, and displays an image (e.g., a frame line) representing the calculated setting range 91 superimposed on the space image 70 via the touch panel 51 as the setting assistance image 90. For example, the setting assistance device 50 uses the aforementioned corresponding information to convert the calculated setting range 91 into a range defined by two-dimensional position coordinates in the space image 70, and superimposes an image representing the converted range onto the space image 70. The calculation of the setting range 91 based on the projection range 81 will be described later.

[0108] Thus, the setting aid 50 calculates the setting range 91 in the space 71 (space) where the projection device 10 is projected through the projection device 10, based on the input of the projection range 81 of the projection device 10 in the space 71 (space), and displays a setting aid image 90, which is formed by overlaying an image representing the calculated setting range 91 on a spatial image 70 representing the space 71.

[0109] Therefore, users can intuitively identify where in space 71 the projection device 10 should be placed to project within the desired projection area 81, thus making the setup of the projection device 10 easier. Furthermore, even if the actual projection device 10 is not present, a setup assistance image 90 can be displayed, making the setup plan for the projection device 10 easy to plan.

[0110] Furthermore, when the imaging range changes due to moving the setting aid 50 or changing its orientation, i.e., when the range of space 71 represented by the spatial image 70 changes, the setting aid 50 can recalculate the range corresponding to the setting range 91 in the spatial image 70 and update the image of the setting range 91 in the setting aid image 90. Therefore, by moving the setting aid 50 or changing its orientation, the user can more intuitively identify the setting range 91 in space 71, thus making the setup of the projection device 10 easier.

[0111] And, as Figure 10 As shown, the setting aid 50 can be displayed on the spatial image 70 and the image of the setting range 91, further superimposed on the projection device image 1001 representing the projection device 10, forming the setting aid image 90. The projection device image 1001 can be moved by the user's operation (e.g., touch operation), and the user can temporarily determine the setting position of the projection device 10 by moving the projection device image 1001. The setting aid 50 can calculate parameters such as the displacement when the projection device 10 is set at the temporarily determined setting position and projected onto the projection range 81, and display an image representing the calculated parameters superimposed on the setting aid image 90. Thus, the user can easily grasp the parameters such as the displacement when the projection device 10 is set at the position of the projection device image 1001 and projected onto the projection range 81, thereby making the setting of the projection device 10 easier. Furthermore, by displaying the projection device image 1001, the user can intuitively identify the setting range 91 as the area where the projection device 10 can be set, thus making the setting of the projection device 10 easier.

[0112] <Structural calculation settings based on space 71, range 91>

[0113] The setting aid 50 calculates the setting range 91, for example, based on the projection range 81 and information representing the structure of the space 71 (which may include obstacles or other structures present in the space 71). The information representing the structure of the space 71 can be obtained, for example, by the space recognition sensor provided with the setting aid 50, or it can be input to the setting aid 50 from the outside as space data.

[0114] For example, such as Figure 8 For example, when the projection range 81 is a rectangular range formed along the wall 71a, the setting aid 50 calculates the setting range 91 as the range within the setting range calculated based on the input of the projection range 81 and the field of view of the projection device 10, excluding the range where the projection is blocked by obstacles in the space between the projection range and the setting range. Thus, the setting range 91 within which the projection light of the projection device 10 will not be blocked can be calculated.

[0115] Thus, by calculating the setting range 91 based on the projection range 81 and the information of the structure of the space 71, the setting auxiliary device 50 can calculate the setting range 91 that can be projected onto the projection range 81 based on the structure of the space 71.

[0116] <Setting range 91 based on the specifications of projection device 10>

[0117] The auxiliary device 50 can perform the following processing: excluding from the setting range 91 areas where the projection device 10 cannot focus on the projection range 81 (wall 71a) due to being too close, or where the projectable range of the projection device 10 cannot cover the projection range 81. This processing is performed, for example, based on information indicating the specifications of the projection device 10, such as the shortest projectable distance or field of view.

[0118] Furthermore, the auxiliary device 50 performs the following processing: it excludes from the setting range 91 any range where the resolution or brightness of the projected image within the projection range 81 cannot meet the reference standard due to being too far from the projection range 81 (wall 71a). This processing is performed, for example, based on information indicating the specifications of the projection device 10, such as information about the longest projection distance at which the resolution or brightness of the projection device 10 meets the reference standard.

[0119] Furthermore, the auxiliary device 50 can expand the setting range 91 according to the displacement range of the projection range 11 of the projection device 10 or the changeable range of the projection direction of the projection device 10. This process is performed, for example, according to information indicating the specifications of the displacement mechanism or the projection direction changing mechanism 104 of the projection device 10.

[0120] Furthermore, the auxiliary device 50 can perform the following processing: based on information indicating the size of the projection device 10 and information indicating the structure of the space 71, it excludes the area from the setting range 91 where the projection device 10 cannot be set in space.

[0121] Furthermore, the auxiliary device 50 can perform the following processing: based on information indicating the position of the air intake or exhaust port of the projection device 10 and information indicating the structure of the space 71, it excludes from the setting range 91 the area where the air intake or exhaust port of the projection device 10 is blocked by a wall or obstacle when the projection device 10 is set.

[0122] Furthermore, the auxiliary device 50 can perform the following processing: based on information indicating the connection position of the cable in the projection device 10 and information indicating the structure of the space 71, exclude from the setting range 91 the range where the cable of the projection device 10 is difficult to connect due to walls or obstacles when setting the projection device 10.

[0123] Thus, by calculating the setting range 91 based on the information indicating the specifications of the projection device 10, the setting auxiliary device 50 can calculate and display an appropriate setting range 91 corresponding to the specifications of the projection device 10 even if there is no actual projection device 10.

[0124] <Calculate setting range 91 based on the non-setting range of device 10>

[0125] The setting auxiliary device 50 can perform processing to exclude the projection device 10 from the space 71 outside the setting range 91. The non-setting range of the projection device 10 refers to the area where the projection device 10 is not set by the user. For example, the passageway, the position visible to the audience, and the position close to the audience (the position where the driving sound or heat of the projection device 10 causes problems) are set as the non-setting range of the projection device 10.

[0126] Thus, by calculating the setting range 91 based on the projection range 81 and the information on the non-setting range of the projection device 10 in the display space 71, the setting auxiliary device 50 can exclude the non-setting range of the projection device 10 set by the user according to various situations from the setting range 91.

[0127] <Calculate the setting range 91 that conforms to the projection quality of the projection device 10>

[0128] The auxiliary device 50 can calculate whether the projection quality of the image projected from the projection device 10 onto the projection area 81 conforms to a reference setting range 91. Projection quality includes, for example, the brightness, resolution, and distortion of the projected image. The brightness of the projected image may include peripheral light attenuation.

[0129] For example, the farther the projection device 10 is located from the projection range 81, the lower the brightness or resolution of the projected image. Therefore, the setting assistance device 50 can perform processing to exclude projected images from the setting range 91 whose brightness or resolution is lower than a predetermined reference.

[0130] Furthermore, if the projection range 11 of the projection device 10 is shifted or the projection direction of the projection device 10 is changed, the projected image of the projection device 10 will be distorted. Even if distortion correction is performed to correct the distortion of the projected image, the brightness or resolution of the projected image will decrease. Therefore, the setting aid 50 can perform processing to exclude projected image distortion exceeding a predetermined reference range from the setting range 91. For example, when the setting aid 50 performs the processing of expanding the setting range 91 according to the displacement range of the projection range 11 of the projection device 10 or the changeable range of the projection direction of the projection device 10, as described above, this expansion processing is performed within the range where the projected image distortion does not exceed the predetermined reference range.

[0131] Thus, by calculating the projection quality of the image projected from the projection device 10 onto the projection range 81 within a set range 91 that conforms to the reference, the auxiliary device 50 can easily set the projection device 10 to conform to the reference.

[0132] <Display of guidance information for the setup assistance device 50 based on embodiment 1>

[0133] Figure 11 This is a diagram illustrating a display example of guidance information from the setup assistance device 50 based on embodiment 1. When the projection quality of the image projected from the projection device 10 onto the projection range 81 does not meet the reference setting range 91, the setup assistance device 50 may display a setup assistance image 90 including information prompting the addition or modification of the projection device 10.

[0134] Information urging the addition of projection device 10 refers to, for example, when projection quality can be improved by using multiple projection devices 10, guiding the user to add a projection device 10 so that the projection quality meets the benchmark. Information urging the modification of projection device 10 refers to, guiding the user to modify projection device 10 to a higher performance projection device so that the projection quality meets the benchmark.

[0135] As an example, such as Figure 11 As shown, the setup assistance device 50 can display a setup assistance image 90 containing guidance information 111 instead of the setup range 91 via the touch panel 51. The guidance information 111 includes messages such as a message indicating that the setup range 91 capable of high-quality projection does not exist, and a message indicating that high-quality projection can be performed by adding a projector (projection device 10).

[0136] <Display of the setting range of the projection device 10 for each projection quality based on the setting assistance device 50 of embodiment 1>

[0137] Figure 12 This diagram illustrates an example of the setting range of the projection device 10 for each projection quality based on the setting assistance device 50 of Embodiment 1. When an image can be projected from the projection device 10 onto the projection range 81 at multiple projection qualities, the setting assistance device 50 can calculate the setting range 91 in the space 71 where the projection device 10 can be set for each of the multiple projection qualities. In this case, the setting assistance device 50 displays a setting assistance image 90, which is formed by overlaying the calculated setting range 91 for each projection quality onto the spatial image 70.

[0138] As an example, when the projection device 10 is capable of both projection with no displacement of the projection range 11 (small distortion of the projected image) and projection with displacement of the projection range 11 (large distortion of the projected image), the setting auxiliary device 50 can display the setting range 91a of the projection device 10 capable of projection with no displacement of the projection range 11 and the setting range 91b of the projection device 10 capable of projection with displacement of the projection range 11.

[0139] At this time, the setting assistance device 50 can display quality information 121a and 121b, representing the projection quality of each setting range 91a and 91b, within the setting assistance image 90. Quality information 121a indicates that setting range 91a is the setting range of the projection device 10 where the distortion of the projected image is relatively small. Quality information 121b indicates that setting range 91b is the setting range of the projection device 10 where the distortion of the projected image is relatively large.

[0140] As various projection qualities, the presence or absence of displacement of the projection range 11 has been described, but the various projection qualities are not limited to this. For example, various projection qualities can be various displacement amounts of the projection range 11, whether or not the projection direction of the projection device 10 changes, or various changes in the projection direction of the projection device 10. Furthermore, various projection qualities can be, for example, various brightness levels of the projected image of the projection device 10, or various resolution levels of the projected image of the projection device 10.

[0141] <Multiple projection devices for setting up assist objects based on the setting assist device 50 of embodiment 1>

[0142] Figure 13This is a schematic diagram illustrating an example of a plurality of projection devices that are the objects of setup assistance based on the setup assistance device 50 of Embodiment 1. The setup assistance device 50 may, for example, display a setup assistance image 90 that assists in setting up the first projection device 10a and the second projection device 10b.

[0143] The first projection device 10a and the second projection device 10b are, for example, the same projection devices as the projection device 10. The first projection range 11a is the area through which projection light is irradiated by the projection section 1 of the first projection device 10a. The second projection range 11b is the area through which projection light is irradiated by the projection section 1 of the second projection device 10b.

[0144] It is possible to project over a larger area using the first projection range 11a and the second projection range 11b. At this time, such as... Figure 13 As shown, a portion of the first projection range 11a and the second projection range 11b can overlap each other.

[0145] <First Example of Setting Assistance for Multiple Projection Devices Based on Setting Assistance Device 50 of Embodiment 1>

[0146] Figure 14 This diagram illustrates a first example of setting assistance for multiple projection devices based on the setting assistance device 50 of Embodiment 1. The setting assistance device 50, for example, calculates a first setting range 91c in space 71 where the first projection device 10a can be set, and a second setting range 91d in space 71 where the second projection device 10b can be set, based on input of the projection range 81a of the first projection device 10a. Furthermore, the first setting range 91c and the second setting range 91d are illustrated more simply than the setting range 91.

[0147] If the first projection device 10a is placed anywhere within the first setting range 91c, and the second projection device 10b is placed anywhere within the second setting range 91d, then the first setting range 91c and the second setting range 91d are calculated in such a way that a larger projection range can be achieved through the first projection range 11a and the second projection range 11b.

[0148] The setting aid device 50 displays a setting aid image 90 on the spatial image 70 by means of a touch panel 51, which is an image (e.g., a frame line) that overlays the calculated first setting range 91c and the second setting range 91d onto the spatial image 70.

[0149] Alternatively, a brighter projection can be achieved by overlapping the first projection range 11a and the second projection range 11b in a manner that aligns the centers of each other. In this case, if the first projection device 10a is placed anywhere within the first setting range 91c and the second projection device 10b is placed anywhere within the second setting range 91d, the first setting range 91c and the second setting range 91d are calculated in a manner that aligns the centers of each other.

[0150] Therefore, by inputting the projection range 81a of the first projection device 10a, the user can intuitively identify where the first projection device 10a and the second projection device 10b should be placed in the space 71, thus making the placement of the first projection device 10a and the second projection device 10b easier.

[0151] Alternatively, when the user changes the projection range 81a, the setting assistance device 50 recalculates the first setting range 91c and the second setting range 91d based on the changed projection range 81, and updates the image representing the first setting range 91c and the second setting range 91d in the setting assistance image 90.

[0152]

[0153] Figure 15 This is a diagram illustrating a second example of setting assistance for multiple projection devices based on the setting assistance device 50 of Embodiment 1. The setting assistance device 50, for example, calculates a first setting range 91c in space 71 that can set the first projection device 10a and a second setting range 91d in space 71 that can set the second projection device 10b, based on the input of a projection range 81b obtained by combining the range projected by the first projection device 10a and the range projected by the second projection device 10b.

[0154] If the first projection device 10a is placed at any point within the first setting range 91c, and the second projection device 10b is placed at any point within the second setting range 91d, then the first setting range 91c and the second setting range 91d are calculated in such a way that the projection range 81b can be projected in accordance with the reference.

[0155] The setting aid device 50 displays a setting aid image 90 on the spatial image 70 via a touch panel 51, which overlays an image (e.g., a frame line) representing the calculated first setting range 91c and the second setting range 91d.

[0156] Therefore, users can intuitively identify where in space 71 the first projection device 10a and the second projection device 10b should be placed to project within the desired projection range 81, thus making the placement of the first projection device 10a and the second projection device 10b easier.

[0157] <Processing of the projection range 81 portion in the setting assistance image 90 of the setting assistance device 50 based on Embodiment 1>

[0158] Figure 16 This diagram illustrates an example of processing of the projection range 81 portion in the setup assistance image 90 based on the setup assistance device 50 of Embodiment 1. The setup assistance device 50 can display the setup assistance image 90, which processes the projection range 81 portion, based on attribute information related to the visibility of the projection range 81 in the space 71.

[0159] Attribute information related to the visibility of the projection range 81 may include, for example, information related to the appearance of the projection range 81 in space 71, such as actual brightness or hue. This attribute information related to the visibility of the projection range 81 can be obtained, for example, by capturing images with a camera included in the setup aid 50. Alternatively, the attribute information related to the visibility of the projection range 81 can be input from the outside into the setup aid 50 as spatial data representing space 71.

[0160] Processing, for example, involves making changes related to the appearance, such as brightness or hue, of the projection range 81 portion in the setting aid image 90. For instance, the setting aid device 50 estimates the brightness or hue of the projected image when projected through the projection device 10 based on attribute information, and processes the projection range 81 portion in the setting aid image 90 in a manner that approximates the estimated brightness or hue.

[0161] Therefore, even without an actual projection device 10, the user can easily grasp the visibility of the projected image within the projection range 81 when the projection device 10 is set up, thus making it easy to plan the setup of the projection device 10. In addition, the setup assistance device 50 can perform processing to overlap the projected sample image in the projection range 81 of the setup assistance image 90 as a processing step.

[0162] <Processing of the setting assistance device 50 based on embodiment 1>

[0163] Figure 17 This is a flowchart illustrating an example of the processing of the setting assistance device 50 based on Embodiment 1. The setting assistance device 50 of Embodiment 1, for example, performs... Figure 17 The processing is shown. Figure 17 Processing, for example, through Figure 6The processor 61 shown is used to execute this. Here, the case of assisting in setting up a projection device 10 will be described.

[0164] First, the setting aid 50 displays the spatial image 70 (step S1701). Next, the setting aid 50 receives input of the projection range 81 from the user (step S1702). Next, the setting aid 50 calculates the setting range 91 that the projection device 10 can project onto the input projection range 81 based on information indicating the specifications of the projection device 10 (step S1703).

[0165] Next, the setting assist device 50 excludes areas that obstruct the projection light from the current setting range 91 based on the information indicating the structure of the space 71 (step S1704). Next, the setting assist device 50 excludes areas from the current setting range 91 where the projection device 10 cannot be set up spatially based on the information indicating the size of the projection device 10 and the information indicating the structure of the space 71 (step S1705).

[0166] Next, the setting assist device 50 excludes the non-setting range set by the user from the current setting range 91 (step S1706). Next, the setting assist device 50 excludes the range whose projection quality does not meet the reference from the current setting range 91 based on the information indicating the specifications of the projection device 10 (step S1707).

[0167] Next, the setting assistance device 50 determines whether there is a remaining setting range 91 after steps S1704 to S1707 (step S1708). If there is a remaining setting range 91 (step S1708: Yes), the setting assistance device 50 displays a setting assistance image 90 superimposed on the spatial image 70 via the touch panel 51 (step S1709), and ends the series of processes. If there is no remaining setting range 91 (step S1708: No), the setting assistance device 50 displays guidance information 111, such as guidance for the addition of the projection device 10, via the touch panel 51 (step S1710), and ends the series of processes.

[0168] exist Figure 17 The process shown may be a process that omits at least some of steps S1704 to S1707, or a process that reverses the order of steps S1704 to S1707.

[0169] Thus, according to the setting assistance device 50 of embodiment 1, it is possible to calculate the setting range 91 in the space 71 where the projection device 10 can be set based on the input of the projection range 81 of the projection device 10 in the space 71 (space) through which the projection is projected by the projection device 10, and display the setting assistance image 90, which is formed by superimposing an image representing the calculated setting range 91 on the spatial image 70 representing the space 71.

[0170] Therefore, users can intuitively identify where in space 71 the projection device 10 should be placed to project within the desired projection area 81, thus making the setup of the projection device 10 easier. Furthermore, even if the actual projection device 10 is not present, a setup assistance image 90 can be displayed, making the setup plan for the projection device 10 easy to plan.

[0171] (Implementation Method 2)

[0172] <Brief Structure of Projection Device 10 for Setting Assist Object Based on Setting Assist Device 50 in Embodiment 2>

[0173] The object to be set up in the setting aid device 50 of Embodiment 2 is the same as the projection device 10 of the object to be set up in the setting aid device 50 of Embodiment 1. The structure of the setting aid device 50 of Embodiment 2 is the same as... Figure 5 , Figure 6 The installation auxiliary device 50 shown in Embodiment 1 is the same.

[0174] In addition to the processing of the setting aid device 50 in Embodiment 1, or in place of the processing of the setting aid device 50 in Embodiment 1, the setting aid device 50 of Embodiment 2 performs the following processing: based on the setting position of the projection device 10 in the space 71 through which the projection is projected and the input of the projection reference information, it calculates the projection range of the projection device 10 in the space 71 and outputs a setting aid image formed by overlaying an image representing the calculated projection range on an image representing the space 71.

[0175] <Setting assistance for projection device 10 based on setting assistance device 50 in embodiment 2>

[0176] Figure 18 and Figure 19 This diagram illustrates an example of setting assistance provided by the projection device 10 based on the setting assistance device 50 of Embodiment 2. (and...) Figure 7 Similarly, in the process shown, the auxiliary device 50 first displays the spatial image 70 via the touch panel 51. Furthermore, as... Figure 18As shown, the setting auxiliary device 50 receives input from the user regarding the setting position of the projection device 10 in the space 71 and the projection reference information. The projection reference information refers to information that can determine the projection object of the projection device 10. For example, the projection reference information is the projection direction of the projection device 10.

[0177] The user specifies the desired location for the projection device 10 in the spatial image 70 displayed on the touch panel 51 via touch operation. For example, suppose there is a table in space 71 where the projection device 10 can be placed, and the spatial image 70 includes this table (illustration omitted). When the user places the projection device 10 on the table, they touch a portion of the table in the spatial image 70.

[0178] For example, the setting assistance device 50 generates corresponding information about the position coordinates of the space 71, which is three-dimensionally identified by the spatial recognition sensor included in the sensor 65, and the position coordinates of the spatial image 70, which is two-dimensionally displayed on the touch panel 51. Furthermore, using this corresponding information, the setting assistance device 50 converts the user-specified setting position in the spatial image 70 displayed on the touch panel 51 into a setting position defined by the position coordinates of the three-dimensionally identified space 71.

[0179] Furthermore, the user specifies the projection direction of the projection device 10 as the projection reference information. For example, the setting assistance device 50 receives input via touch operation, specifying any point in the space 71 represented by the spatial image 70 (up, down, left, right, front, back) as the projection direction of the projection device 10. Thus, the setting assistance device 50 can receive input from the user regarding the setting position of the projection device 10 and the projection reference information. In this example, it is assumed that the depth direction in the space 71 represented by the spatial image 70 is used as the input projection direction of the projection device 10.

[0180] The setting aid 50 determines the projection object of the projection device 10 based on the input setting position and projection reference information of the projection device 10. For example, the setting aid 50 determines an object (e.g., wall 71a) in space 71 that is located on the side of the projection direction of the projection device 10 from the setting position of the projection device 10 as the projection object of the projection device 10.

[0181] The setup assistance device 50 can display a projection device image 181 as a setup assistance image 90 by overlapping the touch panel 51 with the spatial image 70. The projection device image 181 is an image representing the projection device 10, which overlaps with the portion of the spatial image 70 corresponding to the input setup position of the projection device 10. Furthermore, the projection device image 181 becomes an image of the projection device 10 that can be projected into the input projection direction of the projection device 10.

[0182] like Figure 19As shown, the setting auxiliary device 50 calculates the projection range 191 that the projection device 10 in the space 71 can project based on the input setting position and projection reference information of the projection device 10, and displays an image (e.g., a frame line) representing the calculated projection range 191 superimposed on the space image 70 via the touch panel 51 as the setting auxiliary image 90.

[0183] For example, the auxiliary device 50 uses the aforementioned corresponding information to convert the calculated projection range 191 into a range defined by two-dimensional position coordinates in the spatial image 70, and overlays an image representing the converted range onto the spatial image 70. The calculation of the projection range 191 based on the setting position of the projection device 10 and the projection reference information will be described later.

[0184] Thus, the setting auxiliary device 50 calculates the projection range 191 that the projection device 10 in the space 71 (space) is able to project based on the setting position of the projection device 10 in the space 71 (space) through which the projection is projected and the input of the projection reference information, and displays the setting auxiliary image 90, which is formed by superimposing an image representing the projection range 191 on the spatial image 70 representing the space 71.

[0185] Therefore, users can intuitively identify which area of ​​space 71 the projection device 10 can project onto at the desired installation location, thus making the installation of the projection device 10 easier. Furthermore, even if the actual projection device 10 is not present, the installation assistance image 90 can be displayed, making the installation plan for the projection device 10 easy to plan.

[0186] Furthermore, the projection reference information is not limited to the projection direction of the projection device 10; it can be any information desired by the user that can determine the projection object of the projection device 10. For example, the projection reference information can be information that directly represents the projection object of the projection device 10 (e.g., wall 71a). For example, the user touches a portion of the projection object (e.g., part of wall 71a) in the displayed spatial image 70. The setting auxiliary device 50 uses the aforementioned corresponding information to convert the position touched by the user in the spatial image 70 into a position defined by the position coordinates of the three-dimensional recognized space 71, and determines the object located at that position in the space 71 (e.g., wall 71a) as the projection object of the projection device 10.

[0187] Furthermore, the projection reference information can be information indicating a projection object that does not exist in space 71. For example, when a user plans to place a screen in front of wall 71a and project onto that screen using projection device 10, information that can determine the position of the screen is input into the setting aid device 50 as projection reference information.

[0188] Furthermore, when the imaging range changes due to moving the setting aid 50 or changing its orientation, i.e., when the range of space 71 represented by the spatial image 70 changes, the setting aid 50 can recalculate the range corresponding to the projection range 191 in the spatial image 70 and update the image of the projection range 191 in the setting aid image 90. Therefore, by moving the setting aid 50 or changing its orientation, the user can more intuitively identify the projection range 191 in space 71, thus making the setup of the projection device 10 easier.

[0189] <Structural Calculation Projection Range 191 Based on Space 71>

[0190] The auxiliary device 50 is set up to calculate the projection range 191, for example, based on the setting position of the projection device 10, the projection reference information, and the information representing the structure of the space 71.

[0191] For example, the auxiliary device 50 calculates the position closest to the installation position of the projection device 10 among the projection objects (e.g., wall 71a) of the projection device 10, as determined by the projection reference information, and calculates the projection range 191 of the rectangle centered on the calculated projection center. Thus, the projection range 191 can be calculated when projection is performed without displacement or change in projection direction.

[0192] Thus, by calculating the projection range 191 based on the installation position of the projection device 10, the projection reference information, and the information on the structure of the representation space 71, the setting auxiliary device 50 can calculate the projection range 191 that can be projected for the installation position of the projection device 10 according to the structure of the space 71.

[0193] <Calculation of projection range 191 based on the specifications of projection device 10>

[0194] The setting aid 50 can calculate the size and shape of the projection range 191 in the projection object based on the distance between the projection object and the setting position of the projection device 10 determined by the projection reference information, the field of view of the projection of the projection device 10, and the aspect ratio of the projection of the projection device 10. Furthermore, the setting aid 50 calculates the range of a rectangle with the calculated size and aspect ratio centered on the projection center as the projection range 191.

[0195] Furthermore, the setting aid 50 can calculate and expand the projectable range of the projection range 191 based on the displacement range of the projection range 11 of the projection device 10 or the changeable range of the projection direction of the projection device 10. This process is performed, for example, based on information indicating the specifications of the displacement mechanism or the projection direction changing mechanism 104 of the projection device 10. In this case, the setting aid 50 can overlay images representing the projection range 191 and the projectable range onto the setting aid image 90 and display them. Thus, the user can easily grasp the projection range 191 that can be projected without displacement or change of projection direction, and the projectable range that can be projected with displacement or change of projection direction.

[0196] Thus, by calculating the projection range 191 based on information indicating the specifications of the projection device 10, the setting aid 50 can calculate and display an appropriate projection range 191 corresponding to the specifications of the projection device 10, even if the actual projection device 10 does not exist. Furthermore, the setting aid 50 can calculate and display the projectable range that can be projected by the movement of the projection range 11 based on information indicating the specifications related to the movement of the projection range 11 (displacement or change of projection direction).

[0197] <Calculate the projection range 191 based on the non-setting range of the projection device 10>

[0198] The setting aid 50 can be configured such that the user cannot input the setting position of the projection device 10 as the non-setting range of the projection device 10 in the space 71. Thus, the setting aid 50 can be configured such that, based on the non-setting range of the projection device 10 in the space 71, the input setting position of the projection device 10 is restricted, thereby preventing the non-setting range of the projection device 10 set by the user according to various situations from being set as the setting position of the projection device 10.

[0199] <Calculate the projection range 191 that meets the projection quality of the projection device 10>

[0200] The auxiliary device 50 can calculate the projection quality of the image projected from the projection device 10 onto the projection range 81 within a reference setting range 191. For example, if the field of view of the projection device 10 can be changed, increasing the field of view of the projection device 10 will reduce the resolution or brightness of the projected image.

[0201] Therefore, by setting the auxiliary device 50, the projection range can be excluded from the projection range 191 if the resolution or brightness of the projected image is lower than a predetermined reference.

[0202] Thus, by calculating the projection quality of the image projected from the projection device 10 onto the projection range 81, the auxiliary device 50 can easily set the projection device 10 to have a projection quality that conforms to the reference projection range 191.

[0203] <Display of guidance information for the setup assistance device 50 based on embodiment 2>

[0204] Figure 20 This is a diagram illustrating a display example of guidance information from the setup assistance device 50 based on embodiment 2. When the projection quality of the image projected from the projection device 10 onto the projection range 81 does not meet the reference projection range 191, the setup assistance device 50 may display a setup assistance image 90 including information prompting the addition or modification of the projection device 10.

[0205] As an example, such as Figure 20 As shown, the setup assistance device 50 can display a setup assistance image 90, which replaces the projection range 191 and includes guidance information 201, via the touch panel 51. The guidance information 201 includes messages such as a message indicating that the projection range 191 capable of high-quality projection does not exist, and a message indicating that high-quality projection can be achieved by adding a projector (projection device 10).

[0206] <Multiple projection devices for setting up assist objects based on the setting assist device 50 of embodiment 2>

[0207] The setting assistance device 50 in Embodiment 2 is similar to the setting assistance device 50 in Embodiment 1, for example, it can display settings for... Figure 13 The auxiliary image 90 shows the setup of the first projection device 10a and the second projection device 10b.

[0208] <Setting assistance for multiple projection devices based on the setting assistance device 50 of embodiment 2>

[0209] Figure 21 This diagram illustrates an example of setting assistance for multiple projection devices based on the setting assistance device 50 of Embodiment 2. The setting assistance device 50, for example, calculates a first projection range 191a that the first projection device 10a in space 71 can project, and a second projection range 191b that the second projection device 10b in space 71 can project, based on the setting position of the first projection device 10a and the input of projection reference information. Furthermore, the first projection range 191a and the second projection range 191b are illustrated in a simpler way than the projection range 191.

[0210] For example, when the first projection device 10a is set at the input setting position, the first projection range 191a and the second projection range 191b are calculated in such a way that the setting position of the second projection device 10b that can be projected onto the second projection range 191b exists in the space 71.

[0211] The setup assistance device 50 displays a setup assistance image 90 on the spatial image 70 via a touch panel 51, which overlays the calculated first projection range 191a and second projection range 191b (e.g., frame lines).

[0212] Therefore, by inputting the setting position and projection reference information of the first projection device 10a, the user can intuitively identify the projection range based on the first projection device 10a and the second projection device 10b, thus making the setting plan of the first projection device 10a and the second projection device 10b easier.

[0213] In addition, when the user changes the setting position and projection reference information of the first projection device 10a, the setting assistance device 50 recalculates the first projection range 191a and the second projection range 191b according to the changed setting position and projection reference information of the first projection device 10a, and updates the image representing the first setting range 91c and the second setting range 91d in the setting assistance image 90.

[0214] <Processing of the projection range 191 portion in the setting assistance image 90 of the setting assistance device 50 based on Embodiment 2>

[0215] Figure 22 This diagram illustrates an example of processing of the projection range 191 portion in the setup assistance image 90 based on the setup assistance device 50 of embodiment 2. The setup assistance device 50 can display the setup assistance image 90, which processes the projection range 191 portion, based on attribute information related to the visibility of the projection range 191 in space 71.

[0216] Attribute information related to the visibility of the projection range 191 may include information related to the appearance of the projection range 191 in space 71, such as actual brightness or hue. This attribute information related to the visibility of the projection range 191 can be obtained, for example, by capturing images with a camera included in the setup aid 50. Alternatively, the attribute information related to the visibility of the projection range 191 can be input from the outside to the setup aid 50 as spatial data representing space 71.

[0217] Processing, for example, involves making changes related to the appearance, such as brightness or hue, of the projection area 191 portion in the setting aid image 90. For instance, the setting aid device 50 estimates the brightness or hue of the projected image when projected through the projection device 10 based on attribute information, and performs processing on the projection area 191 portion of the setting aid image 90 to make it approximate the estimated brightness or hue.

[0218] Therefore, even without an actual projection device 10, the user can easily grasp the visibility of the projected image within the projection range 191 when the projection device 10 is set up, thus making it easy to plan the setup of the projection device 10. In addition, the setup assistance device 50 can perform processing to overlap the projected sample image in the projection range 191 of the setup assistance image 90 as a processing step.

[0219] <Processing of the setting assistance device 50 based on embodiment 2>

[0220] Figure 23 This is a flowchart illustrating an example of the processing of the setting assistance device 50 based on Embodiment 2. The setting assistance device 50 of Embodiment 2, for example, performs... Figure 23 The processing is shown. Figure 23 Processing, for example, through Figure 6 The processor 61 shown is used to execute this. Here, the case of assisting in setting up a projection device 10 will be described.

[0221] First, the setting aid 50 displays the spatial image 70 (step S2301). Next, the setting aid 50 receives the setting position and projection reference information of the projection device 10 from the user (step S2302). At this time, the setting aid 50 can restrict the setting position of the projection device 10 that can be input by excluding the above-mentioned non-setting range.

[0222] Next, the setting assistance device 50 calculates, based on information indicating the specifications of the projection device 10, the projection range 191 that the projection device 10 can project from the input setting position of the projection device 10, within the projection object determined by the projection reference information (step S2303). At this time, the setting assistance device 50 can further calculate the aforementioned projectable range that can be projected even if there is a displacement or change in the projection direction. Next, the setting assistance device 50 excludes ranges whose projection quality does not meet the reference from the current projection range 191 based on information indicating the specifications of the projection device 10 (step S2304).

[0223] Next, the setting assistance device 50 determines whether there is a remaining projection range 191 after step S2304 (step S2305). If there is a remaining projection range 191 (step S2305: Yes), the setting assistance device 50 displays a setting assistance image 90 on the spatial image 70, which is an image of the projection range 191 superimposed on the spatial image 70, via the touch panel 51 (step S2306), and ends the series of processes. Alternatively, if the setting assistance device 50 also calculated the projectable range in step S2303, in step S2306, it displays a setting assistance image 90 on the spatial image 70, which is an image of the projection range 191 and the projectable range superimposed on the spatial image 70, via the touch panel 51. If there is no remaining projection range 191 (step S2305: No), the setting assistance device 50 displays guidance information 201, such as guidance for adding the projection device 10, via the touch panel 51 (step S2307), and ends the series of processes.

[0224] exist Figure 23 The process shown may, for example, omit step S2304.

[0225] Thus, according to the setting assistance device 50 of embodiment 2, the projection range 191 of the projection device 10 in the space 71 is calculated based on the setting position of the projection device 10 in the space 71 through the projection device 10 and the input of projection reference information, and the setting assistance image 90 is formed by overlaying an image representing the calculated projection range 191 on the spatial image 70 representing the space 71.

[0226] Therefore, users can intuitively identify the desired installation location of the projection device 10 and the range of space 71 that the projection device 10 can project onto, based on the projection reference information, thus making the installation of the projection device 10 easier. Furthermore, even if there is no actual projection device 10, the installation assistance image 90 can be displayed, thus making the installation plan of the projection device 10 easy to perform.

[0228] Modifications related to the above embodiments will be described.

[0229] <Variation Example 1>

[0230] The description has explained the case where the spatial image 70 representing space 71 is a viewfinder image obtained in real time by a camera device provided with the installation auxiliary device 50, but the spatial image 70 is not limited to this. For example, the spatial image 70 may be a still image obtained by photographing space 71 in the past. Furthermore, the spatial image 70 may not be an image obtained by photographing, for example, it may be an image generated based on three-dimensional data representing the structure of space 71.

[0231] <Variation Example 2>

[0232] The description focuses on a tablet terminal with a touch panel 51 as the setup assistance device 50, but the setup assistance device 50 is not limited to this structure. For example, the setup assistance device 50 can be an information terminal such as a smartphone or a personal computer.

[0233] <Variation Example 3>

[0234] The structure of the setting assistance device 50 displaying the setting assistance image 90 has been described. However, the setting assistance device 50 can also be controlled to display the generated setting assistance image 90 on other devices by sending the image to them. In this case, the setting assistance device 50 may be a server device or the like that does not have a display device.
