[0001] The present invention relates to an information processing method, an information processing device, and a program. [Background technology]

[0002] Conventionally, there have been proposals to prevent a projected image of a projector from shifting from its initial position. For example, the projector disclosed in Patent Document 1 corrects an image on a display panel so that the projected image is projected at the initial position when the projector body moves.

[0003] [Patent Document 1] Patent Publication No. 2022-92169 Summary of the Invention [Problem to be solved by the invention]

[0004] The projector described in Patent Document 1 includes a process for moving a panel image formed on a display panel by performing coordinate conversion of the panel image. However, when the panel image is formed on the entire display panel, the panel image cannot be moved. If it is considered to provide an area on the display panel where the panel image is not formed in order to secure an area in which the panel image can be moved, there is a problem that the entire display panel cannot be used to form the panel image due to the function of correcting the projected image. [Means for solving the problem]

[0005] One aspect of the present disclosure is an information processing method that includes receiving a first input indicating whether to disable or enable an adjustment function that aligns a position on a projection surface of a first projection image projected by a first projector to an initial position, determining a drawing area, which is an area in which an image can be drawn on a display panel of the first projector, to a first area when the first input indicating to disable the adjustment function is received, and determining the drawing area to a second area smaller than the first area when the first input indicating to enable the adjustment function is received.

[0006] One aspect of the present disclosure is an information processing device that includes at least one processor and performs the following operations: receiving a first input indicating whether to disable or enable an adjustment function that aligns a position on a projection surface of a first projection image projected by a first projector to an initial position; when receiving the first input indicating to disable the adjustment function, determining a drawing area, which is the area on which the first projector can draw an image, on a display panel of the first projector to be a first area; and when receiving the first input indicating to enable the adjustment function, determining the drawing area to be a second area smaller than the first area.

[0007] One aspect of the present disclosure is a program executable by a computer, which causes the computer to receive a first input indicating whether to disable or enable an adjustment function that aligns a position on a projection surface of a first projection image projected by a first projector to an initial position, and when the first input indicating to disable the adjustment function is received, determine a drawing area, which is the area on which the first projector can draw an image, on a display panel of the first projector to be a first area, and when the first input indicating to enable the adjustment function is received, determine the drawing area to be a second area smaller than the first area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

[0010] [1. Display system configuration] FIG. 1 is a diagram showing an example of the configuration of a display system 1 according to the present embodiment. FIG. 1 shows an X-axis, a Y-axis, and a Z-axis which are perpendicular to each other. The Z-axis indicates the vertical direction. The X-axis and the Y-axis are parallel to the horizontal direction. The X-axis indicates the left-right direction, and the Y-axis indicates the front-back direction. The positive direction of the X-axis indicates the right direction when facing the screen SC, the positive direction of the Y-axis indicates the front direction when facing the screen SC, and the positive direction of the Z-axis indicates the upward direction.

[0011] The system of this embodiment includes a first projector 100A, a second projector 100B, and a control device 300. The control device 300, the first projector 100A, and the second projector 100B are daisy-chain connected by wires. The first projector 100A and the second projector 100B form an image on the screen SC by projecting the image light PL onto the screen SC. In the following description, the formation of an image on the screen SC by the first projector 100A and the formation of an image on the screen SC by the second projector 100B are referred to as display. The screen SC corresponds to an example of a projection surface in the present disclosure.

[0012] The control device 300 is connected to the first projector 100A by wire, and outputs an image signal to the first projector 100A. The first projector 100A is connected to the control device 300 and the second projector 100B by wire, and outputs an image signal input from the control device 300 to the second projector 100B. The control device 300 is, for example, a personal computer, a tablet terminal, or the like.

[0013] In this embodiment, an example in which the control device 300, the first projector 100A, and the second projector 100B are connected by wire will be described, but the control device 300, the first projector 100A, and the second projector 100B may be connected wirelessly. Also, the first projector 100A and the second projector 100B may each be connected to the control device 300 by wire.

[0014] The first projector 100A operates as a primary device, and the second projector 100B operates as a secondary device. During initial setting, which will be described later, the first projector 100A, which is the primary device, outputs instructions to the second projector 100B, which is the secondary device, and controls the operation of the second projector 100B.

[0015] The first projector 100A includes a projector body 10A, an optical system unit 400A, and a first camera 200A. The projector body 10A is installed suspended from the ceiling. The optical system unit 400A is attached to a mounting portion 105A of the projector body 10A so as to be able to project image light PLA onto the screen SC. The first camera 200A is connected to the projector body 10A so as to be able to communicate with the projector body 10A, and is installed on a mounting portion 911A of the optical system unit 400A so as to be able to capture the first projection image PA displayed on the screen SC.

[0016] The second projector 100B includes a projector body 10B, an optical system unit 400B, and a second camera 200B. The projector body 10B is installed suspended from the ceiling. The optical system unit 400B is attached to a mounting portion 105B of the projector body 10B so as to be able to project the image light PLB onto the screen SC. The second camera 200B is connected to the projector body 10B so as to be able to communicate with the projector body 10B, and is installed on a mounting portion 911B of the optical system unit 400B so as to be able to capture the second projection image PB displayed on the screen SC.

[0017] The projector body 10A extracts image data contained in an image signal input from the control device 300, and generates image light PLA corresponding to the extracted image data. The optical system unit 400A projects the image light PLA generated by the projector body 10A onto the screen SC. The first camera 200A captures an image of an area of ​​the screen SC including the first projection image PA displayed on the screen SC, and generates a captured image. The generated captured image is used, for example, for color adjustment of the first projection image PA.

[0018] The projector body 10B extracts image data contained in the image signal input from the first projector 100A, and generates image light PLB corresponding to the extracted image data. The optical system unit 400B projects the image light PLB generated by the projector body 10B onto the screen SC. 2 Camera 200 B is the first image displayed on the screen SC. 2Projected image P B The area of ​​the screen SC including the first projection image PB is imaged to generate a captured image. The generated captured image is used, for example, for color adjustment of the second projection image PB.

[0019] 1 shows that a first projector 100A and a second projector 100B are installed by being suspended from the ceiling on the user side with respect to a rectangular screen SC installed on a vertical wall. A viewer who is a user views an image displayed on the screen SC located below the first projector 100A and the second projector 100B.

[0020] 1, the first projected image PA and the second projected image PB are displayed side by side in the left-right direction of the screen SC, and one large horizontally long image is tiled. When the first projected image PA and the second projected image PB are tiled, the first projector 100A and the second projector 100B project the image light PLA and the image light PLB so that an overlapping area DPA is generated where the first projected image PA and the second projected image PB overlap.

[0021] As shown in FIG. 1, the first projected image PA is composed of a first non-overlapping image PA1 corresponding to the first non-overlapping area NDP1 and a first superimposed image PA2 corresponding to the superimposed area DPA. The first non-overlapping area NDP1 indicates the area other than the superimposed area DPA among the areas corresponding to the first projected image PA. The second projected image PB is composed of a second non-overlapping image PB1 corresponding to the second non-overlapping area NDP2 and a second superimposed image PB2 corresponding to the superimposed area DPA. The second non-overlapping area NDP2 indicates the area other than the superimposed area DPA among the areas corresponding to the second projected image PB. The luminance of the first superimposed image PA2 is adjusted to be lower than the luminance of the first non-superimposed image PA1, and the luminance of the second superimposed image PB2 is adjusted to be lower than the luminance of the second non-superimposed image PB1. Such a process of adjusting the luminance in the superimposed area DPA is called an edge blending process.

[0022] In order to display the first projected image PA and the second projected image PB side by side in the left-right direction of the screen SC and tile a single large horizontally elongated image, the control device 300 supplies image data that is the basis of the single large horizontally elongated image to the first projector 100A. When the first projector 100A extracts image data from the image signal supplied from the control device 300, the first projector 100A cuts out image data that corresponds to the range of the image to be projected by the first projector 100A in accordance with the range information. The image data of the cut-out range is referred to as first partial image data. The second projector 100B extracts image data from the image signal supplied from the first projector 100A, and cuts out image data that corresponds to the range of the image to be projected by the second projector 100B according to the range information. The image data of the cut-out range is called second partial image data.

[0023] The range information includes information in the image data indicating the range onto which the first projector 100A projects an image, and information in the image data indicating the range onto which the second projector 100B projects an image. The range information is generated, for example, by an operator operating the control device 300. The generated range information is output from the control device 300 to the first projector 100A before starting image projection. The first projector 100A outputs the range information input from the control device 300 to the second projector 100B.

[0024] The first projector 100A and the second projector 100B have substantially the same configuration. In this embodiment, when there is no distinction between the first projector 100A and the second projector 100B, they are described as projectors 100. When there is no distinction between the projector body 10A and the projector body 10B, they are described as projector bodies 10. When there is no distinction between the first camera 200A and the second camera 200B, they are described as cameras 200. When there is no distinction between the optical system unit 400A and the optical system unit 400B, they are described as optical system units 400. When there is no distinction between the image light PLA and the image light PLB, they are described as image light PL.

[0025] [2. Projector configuration] FIG. 2 is a diagram showing an example of the configuration of the first projector 100A. The first projector 100A includes a projector body 10A, an optical system unit 400A, and a first camera 200A.

[0026] The projector main body 10A includes a projection unit 110A, a drive unit 120A, an image interface 131A, an input interface 133A, a remote control light receiving unit 135A, an image processing unit 140A, a frame memory 145A, and a control unit 150A. Hereinafter, the interface is abbreviated to I / F. The image I / F 131A, the input I / F 133A, the image processing unit 140A, and the control unit 150A are connected to each other via a bus 103A so as to be able to communicate data with each other.

[0027] The projection section 110A includes a light source 111A and a light modulation device 112A, and forms an optical image to generate image light PLA. The drive section 120A includes a light source drive section 121A and a light modulation device drive section 122A.

[0028] The light source 111A includes a lamp such as a halogen lamp, a xenon lamp, or an extra-high pressure mercury lamp, or a solid-state light source such as an LED (Light Emitting Diode) or a laser light source. The light source driving section 121A turns on and off the light source 111A in accordance with instructions from the control section 150A.

[0029] The light modulation device 112A includes a liquid crystal panel 115A that modulates the light passing therethrough to generate image light PLA. The liquid crystal panel 115A includes a liquid crystal panel corresponding to red light, a liquid crystal panel corresponding to green light, and a liquid crystal panel corresponding to blue light. A The light emitted by the liquid crystal panel 115 is separated into three color lights of red, green, and blue, and each of the color lights is incident on the corresponding liquid crystal panel 115A. AThe image light PLA modulated by transmitting through each of the light sources 115A and 115B is synthesized by a synthesis optical system such as a cross dichroic prism, and is output to the optical system unit 400 A. The liquid crystal panel 115A corresponds to an example of a display panel of the present disclosure.

[0030] The light modulation device driving unit 122A drives the light modulation device 112A. Image data corresponding to each of the primary colors of red, green, and blue is input to the light modulation device driving unit 122A from the image processing unit 140A. The light modulation device driving unit 122A converts the input image data into a data signal suitable for the operation of the liquid crystal panel 115A. Based on the converted data signal, the light modulation device driving unit 122A applies a voltage to each pixel of the liquid crystal panel 115A to draw an image on the liquid crystal panel 115A.

[0031] The optical system unit 400A is mounted on the mounting portion 105A of the projector body 10A, and includes lenses, mirrors, etc. (not shown) that form an image on the screen SC from the image light PLA generated by the projection portion 110A. A first camera 200A is attached to the optical system unit 400A so that an area including the projected image P displayed on the screen SC becomes an imaging range. The optical system unit 400A may include a zoom mechanism that enlarges or reduces the image projected on the screen SC, a focus adjustment mechanism that adjusts the focus, etc.

[0032] The first camera 200A includes an imaging section 210A and is attached to the mounting section 911A of the optical system unit 400A. The imaging section 210A includes a lens and an imaging element. The lens focuses incident light from an imaging range on the imaging element. The imaging element is formed of a CCD (Charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), or the like, and generates an image signal. The first camera 200A captures the first projected image PA displayed on the screen SC by the imaging section 210A under the control of the projector main body 10A, and transmits the captured image data to the image I / F 1 of the projector main body 10A. 3 Output to 1A.

[0033] The image I / F 131A includes a connector and an interface circuit, and is connected by wire to a control device 300 that supplies image data to the first projector 100A, and to a first camera 200A that supplies a captured image.

[0034] The input I / F 133A includes an interface circuit, and is connected to a remote control light receiving unit 135A. The remote control light receiving section 135A receives an infrared signal transmitted by the remote control 250. The input I / F 133A decodes the signal received by the remote control light receiving section 135A, generates an operation signal, and outputs the operation signal to the control section 150A.

[0035] The frame memory 145A is a storage device that includes a plurality of banks, each of which has a storage capacity capable of writing one frame's worth of image data.

[0036] Image processing unit 140A develops image data input from control device 300 in frame memory 145A. Image I / F 131A extracts image data from an image signal input from an external device, and outputs the extracted image data to image processing unit 140A. The image processing unit 140A performs image processing such as resolution conversion, resizing, distortion correction, shape correction, digital zooming, and adjustment of image color and brightness on the image data expanded in the frame memory 145A.

[0037] The image processing unit 140A and the frame memory 145A are configured, for example, by an integrated circuit. The integrated circuit includes a large scale integrated circuit (LSI), an application specific integrated circuit (ASIC), a programmable logic device (PLD), a field programmable gate array (FPGA), a system on a chip (SoC), etc. An analog circuit may be included as part of the configuration of the integrated circuit, or the control unit 150A may be configured in combination with the integrated circuit.

[0038] The control unit 150A includes a storage unit 160A and a processor 170A. The storage unit 160A includes a volatile storage device and a non-volatile storage device. The volatile storage device is, for example, a random access memory (RAM) or the like. The non-volatile storage device is, for example, a read only memory (ROM), a flash memory, an electrically erasable programmable read-only memory (EEPROM), or the like. The volatile storage device is used as a calculation area for the processor 170A. The non-volatile storage device stores the control program 165A executed by the processor 170A. The control unit 150A corresponds to an example of an information processing device, and is a computer.

[0039] The processor 170A is an arithmetic processing device including a processor such as a CPU (Central Processing Unit) or an MPU (Micro-Processing Unit). The processor 170A may be configured with a single processor, or may be configured with multiple processors. The processor 170A may be configured with an SoC integrated with a part or all of the storage unit 160A or other circuits. The processor 170A may be configured with a combination of a CPU that executes a program and a DSP (Digital Signal Processor) that executes a predetermined arithmetic processing. Furthermore, the processor 170A may be configured with all of its functions implemented in hardware, or may be configured using a programmable device.

[0040] [3. Display system operation] Each of the first projector 100A and the second projector 100B has a position maintaining function. The position maintaining function of the first projector 100A is a function of maintaining the position of the first projected image PA on the screen SC at a specified position. Similarly, the position maintaining function of the second projector 100B is a function of maintaining the position of the second projected image PB on the screen SC at a specified position. The position maintaining function corresponds to an example of the adjustment function.

[0041] After the projector 100 is installed, a slight change may occur in the relative position or direction between the projector body 10 and the screen SC. This change may cause the positions of the first projected image PA and the second projected image PB on the screen SC to change. Therefore, when the position of the first projected image PA on the screen SC changes, the first projector 100A adjusts the position of the first projected image PA to match its initial position using a position maintenance function, and this adjustment offsets the change. The same applies to the second projector 100B.

[0042] The position maintaining function of this embodiment is a function for adjusting the position of the projected image P by correcting the image drawn on the liquid crystal panel 115A without moving or displacing the projector body 10 or the optical system unit 400.

[0043] In the first projector 100A, the user can perform settings related to the position maintaining function by operating the remote control 250 or the like. This setting includes switching between enabling and disabling the position maintaining function. The same applies to the second projector 100B. Here, the operation related to the setting of the position maintaining function will be described with reference to each of FIGS. 3 to 9, taking as an example a case where the user operates the first projector 100A.

[0044] Figures 3 and 4 are flowcharts showing the operation of the display system 1. Figures 5 and 6 show a display example of a menu screen, and Figure 7 is a schematic diagram showing a drawing area on the liquid crystal panel 115A. Figures 8 and 9 show an example of a margin display. 3 shows the operation related to setting the position maintaining function of the first projector 100A. The operations of steps S11 to S24 are executed by the processor 170A.

[0045] 3 is started in a state where the menu screen 500 is displayed by the first projector 100A. The menu screen 500 is a screen for setting the functions of the first projector 100A, and is displayed, for example, by an OSD (On Screen Display). The processor 170A controls the image processing unit 140A to form display data for displaying the menu screen 500 in the frame memory 145A, and draws the menu screen 500 on the liquid crystal panel 115A.

[0046] The control unit 150A accepts an operation to instruct the start of the setting (step S11), and displays the menu screen 500 for setting the position maintaining function in a restricted state (step S12). An example of the menu screen 500 displayed in step S12 is shown in FIG.

[0047] As shown in FIG. 5, the menu screen 500 includes a function selection section 510 and an input section 520. In the function selection section 510, items to be set by the menu screen 500 are arranged side by side. For example, the function selection section 510 includes an image quality menu selection section 511, a video menu selection section 512, a setting menu selection section 513, a network menu selection section 514, an initialization menu selection section 515, and an overall setting menu selection section 516. These function as operation sections for selecting setting items. When the user makes a selection in the function selection section 510 by operating the remote control 250 or the like, setting of the function corresponding to the selected operation section is started. For example, the image quality menu selection section 511 corresponds to a function for setting the image quality of the first projected image PA. The video menu selection section 512 corresponds to a function for setting the image displayed by the first projector 100A. The setting menu selection section 513 corresponds to a function for making basic settings of the first projector 100A. The network menu selection section 514 corresponds to a function for making communication settings of the first projector 100A. The initialization menu selection unit 515 is an operation unit for instructing the initialization of the first projector 100A. The overall setting menu selection unit 516 corresponds to a function for making overall settings of the display system 1. The operation accepted by the first projector 100A in step S11 is, for example, an operation for selecting the setting menu selection unit 513.

[0048] Input unit 520 has an input unit and an instruction unit for inputting and selecting a setting value for each setting item related to the function selected in function selection unit 510. In the example of Fig. 5, an input unit and an instruction unit related to the position maintenance function are arranged in input unit 520. For example, input unit 520 includes a position maintenance input unit 521, a margin input unit 522, a tiling setting unit 523, an initial setting start instruction unit 524, and a schedule input unit 525.

[0049] The position maintenance input unit 521 is an input unit to which whether to enable or disable the position maintenance function is input, and for example, accepts an input to select a pull-down menu. The margin input unit 522 accepts an input of the size of a margin area used in the position maintenance function. The tiling setting unit 523 is an instruction unit that instructs the setting of tiling by the first projector 100A and the second projector 100B. The initial setting start instruction unit 524 is an instruction unit that instructs the initial setting of the position maintenance function. The input using the initial setting start instruction unit 524 corresponds to an example of a third input. The initial setting start instruction unit 524, or the input unit 520 including the initial setting start instruction unit 524, corresponds to an example of a user interface that accepts a third input. The schedule input unit 525 is an instruction unit that instructs the schedule setting of the position maintenance function.

[0050] In step S12, control unit 150A displays menu screen 500 in a restricted state. The restricted state refers to a state in which input unit 520 does not accept input or instructions for some setting items, as shown in Fig. 5. In the example of Fig. 5, margin input unit 522, tiling setting unit 523, initial setting start instruction unit 524, and schedule input unit 525 are in a state in which they do not accept input or instructions.

[0051] In the menu screen 500 in the restricted state, the display mode of the setting items that do not accept input or instructions is a limited display mode so that the user can know that the input or instructions are not accepted. The limited display mode is, for example, a mode filled with gray or other colors. In the menu screen 500 of FIG. 5, an input to disable the position maintenance function is made in the position maintenance input section 521. The margin input section 522, the tiling setting section 523, the initial setting start instruction section 524, and the schedule input section 525 are setting items related to the position maintenance function. If the position maintenance function is disabled, there is no need to set it. In other words, the user can efficiently set it by first inputting to enable the position maintenance function in the position maintenance input section 521, and then inputting or instructing using the margin input section 522, the tiling setting section 523, the initial setting start instruction section 524, and the schedule input section 525. Displaying the menu screen 500 in the restricted state has the effect of clearly indicating the order of operations to the user. Displaying the menu screen 500 in a restricted state, in particular displaying the initial setting start instruction portion 524 in a restricted state, corresponds to an example of disabling the user interface.

[0052] The display manner of the margin input section 522, the tiling setting section 523, the initial setting start instruction section 524, and the schedule input section 525 in the restricted state is not limited to the example in Fig. 5. For example, it is also possible to set these input sections and instruction sections not to be displayed on the menu screen 500 in the restricted state. Furthermore, the control section 150A may operate not to accept input to the margin input section 522, the tiling setting section 523, the initial setting start instruction section 524, and the schedule input section 525 in the restricted state. In this case, the display manner in the restricted state may be displayed in the same manner as the first setting possible state and the second setting possible state described later.

[0053] Returning to Fig. 3, control unit 150A receives a first input (step S13). In step S13, control unit 150A receives an input while displaying menu screen 500. The first input is an input indicating whether to enable or disable the position maintenance function of first projector 100A, and is, for example, an operation on position maintenance input unit 521 in Fig. 5.

[0054] The control unit 150A determines whether the first input is an input that enables the position maintaining function (step S14). If the first input is an input that enables the position maintaining function (step S14 / YES), the control unit 150A updates the menu screen 500, which is in a restricted state, to a first setting possible state (step S15).

[0055] FIG. 6 shows the menu screen 500 when the state is updated from the restricted state to the first setting possible state. In the menu screen 500 in the first setting possible state, an input to enable the position maintaining function is made in the position maintaining input section 521. The margin input section 522 is displayed in a state where an input is possible, and the tiling setting section 523 is displayed in a state where an instruction is possible. In the menu screen 500 in the first setting possible state, the initial setting start instruction section 524 and the schedule input section 525 are displayed in a state where an instruction or input is not possible. These instruction sections become instruction possible after a valid value is input in the margin input section 522. The state where the initial setting start instruction section 524 and the schedule input section 525 can be instructed corresponds to the second setting possible state described later.

[0056] 3, the control unit 150A receives a second input (step S16). The second input is an input indicating a margin value.

[0057] The margin is an area of ​​the liquid crystal panel 115A that can be drawn by the light modulation device driving unit 122A, which is provided to perform a position maintaining function and is an area that is not used for drawing by the liquid crystal panel 115A. The margin value is a value indicating the area or size of the margin.

[0058] Fig. 7 shows a schematic example of an example in which a margin is provided on one liquid crystal panel 115A. The first projector 100A includes a liquid crystal panel 115A that modulates red light, a liquid crystal panel 115A that modulates blue light, and a liquid crystal panel 115A that modulates green light. The margins are set in the same manner for these three liquid crystal panels 115A. For this reason, Fig. 7 shows one liquid crystal panel 115A.

[0059] In the liquid crystal panel 115A, an area in which an image can be formed under the control of the light modulation device driving unit 122A is defined as a drawing possible area 190. Pixels driven by the light modulation device driving unit 122A are arranged in the drawing possible area 190, and these pixels modulate the light emitted by the light source 111A.

[0060] The first projector 100A does not normally use the entirety of the drawing possible area 190, but uses an effective area 191 provided in the drawing possible area 190 to draw an image. The image formed in the effective area 191 is projected in its entirety onto the screen SC as the first projection image PA. In other words, the effective area 191 is an area available for the first projector 100A to form the first projection image PA. When the first projector 100A forms an image using the entirety of the effective area 191, the number of pixels corresponding to the first projection image PA is the largest, and it can be said to be an image of the highest quality. The area of ​​the drawing possible area 190 that is not included in the effective area 191 is used, for example, in adjustments to eliminate individual differences of the first projector 100A in the manufacturing process of the first projector 100A.

[0061] When performing geometric correction, the first projector 100A uses a part of the effective area 191. When the geometric correction is performed to display the rectangular first projection image PA on the screen SC, an image that is a deformed rectangle is drawn on the liquid crystal panel 115A. Therefore, the area in which an image can be drawn on the liquid crystal panel 115A after the geometric correction is smaller than the effective area 191. This area is called the image formation area 193. The example in FIG. 7 shows a case in which the image formation area 193 can be made rectangular without performing geometric correction or even with the geometric correction, and the effective area 191 and the image formation area 193 coincide with each other.

[0062] When the first projector 100A executes the position maintaining function, the position of the image drawn on the liquid crystal panel 115A is changed in order to align the position of the first projection image PA on the screen SC to the initial position. Here, for example, in a state where an image is drawn over the entire image forming area 193, if the position of the image is moved on the liquid crystal panel 115A, the image will deviate from the image forming area 193. Therefore, in order to execute the position maintaining function, an area where the image is not drawn is secured in advance in preparation for the movement of the image. For this reason, an area smaller than the image forming area 193 is used for drawing.

[0063] When the position maintaining function is enabled, the first projector 100A sets a drawing area 195 that is smaller than the image forming area 193. The drawing area 195 is an area in which an image is formed by the light modulation device driving unit 122A when the position maintaining function is enabled. The area of ​​the image forming area 193 that is not included in the drawing area 195 is the margin described above.

[0064] The margin value may be a value that specifies the size of the area to be the margin, or may be a value that specifies the size or position of the drawing area 195. The margin value may be the number of pixels, or may be a ratio of the area or number of pixels in the image formation area 193. The ratio is expressed in units of, for example, %. The drawing area 195 is, for example, similar in shape to the image formation area 193. The position of the drawing area 195 can be set to the center of the image formation area 193 in the initial state. The area of ​​the image formation area 193 is an example of a first area, and the area of ​​the drawing area 195 is an example of a drawing area. When the position maintenance function is set to be disabled, the drawing area 195 is the entire image formation area 193, so that the drawing area matches the area of ​​the image formation area 193. In other words, when the position maintenance function is set to be disabled, the area of ​​the drawing area 195 is determined to be the first area. Also, when the position maintenance function is set to be enabled, the drawing area is determined to be the second area that is smaller than the image formation area 193. The margin value, or the area of ​​image formation area 193 calculated from the margin value, is an example of information indicating the second area. When the margin value is specified by the second input, this second input corresponds to an example of a second input indicating the size of the second area. When the position maintenance function is enabled, an image is formed in drawing area 195, which is smaller than image formation area 193, on liquid crystal panel 115A. This image corresponds to an example of an image of the second area.

[0065] Returning to FIG. 3, the control unit 150A switches the display mode of the first projected image PA to a margin display in response to the second input (step S17). Fig. 8 shows an example of margin display. In the example shown in Fig. 8, a maximum area frame 601, which is a frame-shaped image, is added to the first projected image PA including the menu screen 500 so that the user can recognize the size of the margin specified by the second input. The maximum area frame 601 indicates the outer edge of the image formation area 193 in Fig. 7. Furthermore, when margin display is executed, a drawing area frame 602, which is a frame-shaped image indicating the outer edge of the drawing area 195, is displayed.

[0066] During margin display, control unit 150A changes the size and position of drawing area 195 every time a margin value is input or changed in margin input section 522. Control unit 150A updates drawing area frame 602 to match drawing area 195 after the change.

[0067] While the margin display is being performed, an image 603 including the menu screen 500 is displayed. Since the image 603 is drawn in the drawing area 195, the area of ​​the image 603 is updated together with the drawing area frame 602 every time the margin value in the margin input section 522 is input or changed.

[0068] On the menu screen 500 displayed while the margins are displayed, input to the margin input section 522 is possible. Therefore, the user can change the margin value to be input to the margin input section 522 while comparing the image 603 and the drawing area frame 602 with the maximum area frame 601.

[0069] The control unit 150A may start the margin display before accepting the second input in step S16. In this case, in the initial state of the margin display, the drawing area frame 602 and the image 603 are displayed with the margin value set to the initial value.

[0070] The manner in which the maximum area frame 601 and the drawing area frame 602 are displayed when margin display is executed can be changed as appropriate as long as the user can compare the image formation area 193 and the drawing area 195. The first projected image PA including the drawing area frame 602 corresponds to an example of a first projected image showing an area corresponding to the second area, the maximum area frame 601 corresponds to an example of an area display image, and the drawing area frame 602 corresponds to an example of an image of the second area. The first projected image PA Projecting onto the screen SC corresponds to projecting onto the projection surface an area display image showing an area corresponding to the first area. Projecting onto the screen SC the first projection image PA based on the size of the margin specified by the second input corresponds to projecting onto the projection surface a first projection image showing an area corresponding to the second area.

[0071] Fig. 9 shows another example of margin display. In the example of Fig. 9, the area between the maximum area frame 601 and the drawing area frame 602 is colored. The display color of this area is preferably a color different from that of the image 603, and may be the same color as the maximum area frame 601. The example of Fig. 9 has the advantage that the user can easily confirm the area corresponding to the margin value. In addition, the inside of the maximum area frame 601 may be highlighted in a highly visible color such as a fluorescent color, the drawing area frame 602 may be displayed in the same color as the image 603, or various other display modes may be adopted.

[0072] Furthermore, during margin display, the margin value input in margin input section 522 may be displayed in image 603 at a position separate from menu screen 500 or enlarged and superimposed on menu screen 500.

[0073] Returning to FIG. 3, when the user performs an operation to determine the margin value input to the margin input unit 522, the control unit 150A determines the margin value (step S18). That is, the size of the area of ​​the drawing region 195 is determined based on the input to the margin input unit 522. Alternatively, the second input to the margin input unit 522 can be said to be an input indicating the area where drawing is not performed on the liquid crystal panel 115A. The control unit 150A transmits the margin value to the second projector 100B (step S19). Here, the second projector 100B determines the margin value of the second projector 100B based on the margin value transmitted by the first projector 100A. This allows the user to set the margin value in the second projector 100B, which is the secondary device, by inputting the margin value in the first projector 100A, which is the primary device. In addition, the settings of the first projector 100A and the second projector 100B, which perform tiling, can be matched.

[0074] The control unit 150A may display the second projected image PB with a margin while the first projected image PA is being displayed with a margin in step S17, or after the margin display of the first projected image PA is completed. In this case, a drawing area 195 is set in the liquid crystal panel of the second projector 100B according to the margin value, and the second projected image PB is displayed in a manner showing the drawing area 195 and the image forming area 193 of the liquid crystal panel. When the margin display is executed, the first projected image PA and the second projected image PB may be displayed simultaneously on the screen SC, or the first projected image PA and the second projected image PB may be displayed by switching between them at different display timings.

[0075] Next, control unit 150A updates menu screen 500 to a second setting possible state (step S20). In the second setting possible state, initial setting start instruction unit 524 and schedule input unit 525, which were displayed as inoperable in the first setting possible state, are made inoperable. Since the margin value is determined in step S18, the initial setting of the position maintenance function can be executed, and therefore it is appropriate to transition menu screen 500 to the second setting possible state.

[0076] The control unit 150A performs tiling setting in response to an instruction from the tiling setting unit 523 (step S21). The tiling setting is a setting related to the tiling display of the first projected image PA and the second projected image PB, such as a setting of the size of the overlapping area DPA. In step S21, the setting may be performed automatically using images captured by the first camera 200A of the first projected image PA and the second projected image PB.

[0077] The control unit 150A executes the initial setting in accordance with the instruction by the initial setting start instruction unit 524 (step S22). The initial setting in step S22 is a setting related to the position maintaining function. The details of the initial setting will be described later with reference to FIG.

[0078] The control unit 150A sets a schedule based on the input to the schedule input unit 525 (step S23). It is preferable that the position maintaining function is executed periodically after the installation of the display system 1, or whenever a predetermined time has elapsed. The timing at which the first projector 100A executes adjustment using the position maintaining function can be input to the initial setting start instruction unit 524. Specifically, the date and time at which the adjustment is executed, or the interval of days or times at which the adjustment is executed can be mentioned. Here, the time may be the accumulated value of the usage time of the first projector 100A or the time at which the first projected image PA is projected.

[0079] Moreover, if the first input to the position maintenance input section 521 is not an input to enable the position maintenance function, that is, an input indicating that the position maintenance function is to be disabled (step S14 / NO), the control section 150A executes tiling setting (step S24). Since the position maintenance function is disabled in step S24, the control section 150A displays the margin input section 522, the initial setting start instruction section 524, and the schedule input section 525, for example, in a display mode of a restricted state, and sets them to a state in which no instructions or inputs are accepted. In step S24, the control section 150A adjusts the positions of the first projected image PA and the second projected image PB.

[0080] FIG. 4 is a flowchart showing the details of the initial setting in step S22. The control unit 150A executes shooting by the first camera 200A (step S31) and acquires a shot image. The control unit 150A detects feature points from the shot image (step S32). The feature points are points that serve as a reference for the position of the first projected image PA in the shot image. The control unit 150A performs feature point extraction on the shot image using a known image processing method to detect feature points included in the shot image and specify the coordinates of the feature points in the shot image. The feature points are, for example, images of real objects placed on the screen SC. Specifically, when a marker that serves as a reference for the position of the first projected image PA is placed on the screen SC or on the edge of the screen SC, the image of the marker is detected as a feature point in the shot image. The marker is a disk-shaped object, a frame of the screen SC, a sticker attached to the screen SC, or the like. It is preferable for the user to place a marker on the screen SC before performing initial settings. When a large number of feature points are detected, such as when the image of the marker in the captured image is equal to or larger than a predetermined size, the control unit 150A may narrow down the feature points by a known method.

[0081] The control unit 150A determines whether or not there are feature points in the captured image (step S33). In step S33, the control unit 150A may determine whether or not there are a required number of feature points for performing initial setting. If it is determined that there are feature points (step S33 / YES), the control unit 150A requests the user to confirm the feature points (step S34). Here, the control unit 150A requests the user to confirm the positions of the feature points by, for example, displaying a position setting screen 530 on the screen SC.

[0082] 10 is an explanatory diagram showing the initial setting of the display system 1, and shows a state in which a position setting screen 530 is displayed on the screen SC. The position setting screen 530 is an image including a drawing area frame 602 and a pointer M. The pointer M is an image arranged according to the position of a feature point detected by the control unit 150A, and is composed of a figure or an icon. On the position setting screen 530, for example, a menu screen 500 may be displayed inside the drawing area frame 602.

[0083] The user checks whether the position of pointer M on position setting screen 530 matches the marker position intended by the user. If the position of pointer M differs from the user's intention, the user can have first projector 100A perform the initial settings again.

[0084] After the positions of the feature points are confirmed, the control unit 150A selects feature points to be used for determining the position of the first projected image PA from the detected feature points (step S35). Specifically, if a number of feature points exceeding a required number are detected in step S32, the control unit 150A automatically selects the required number of feature points. Alternatively, the control unit 150A may allow the user to select the feature points.

[0085] The control unit 150A determines an initial position of the first projected image PA in accordance with the position of the feature point selected in step S35 (step S36). For example, the control unit 150A converts the coordinates of the feature point in the captured image into coordinates on the liquid crystal panel 115A, and sets the converted coordinates as the coordinates of the vertices of the drawing area 195. The control unit 150A stores information about the determined initial position in the storage unit 160A.

[0086] The control unit 150A determines whether or not the setting has been completed for all the projectors 100 performing tiling display (step S37). For example, in the display system 1 shown in FIG. 1, the control unit 150A determines whether or not the initial positions have been determined for both the first projector 100A and the second projector 100B. If the setting has been completed for all the projectors 100 (step S37 / YES), the control unit 150A ends this process. If the setting has not been completed for all the projectors 100 (step S37 / NO), the control unit 150A causes the projectors 100 for which the setting has not been completed to execute steps S31 to S37.

[0087] Moreover, when it is determined in step S33 that there is no feature point (step S33 / NO), the control unit 150A notifies the user that no feature point was detected (step S38). The notification in step S38 is, for example, displaying a notification message by the first projector 100A. After that, the control unit 150A clears the setting contents of the initial positions of all the projectors 100 performing tiling display (step S39), and returns to step S31.

[0088] When the notification is given in step S38, the user performs an operation such as rearranging the markers on the screen SC. In this case, since the positions and number of the markers change, it is preferable not to use the initial positions determined based on the previous markers. For this reason, the control unit 150A clears the settings in step S39 and maintains consistency between the settings and the marker positions.

[0089] 11 is a flowchart showing an example of the operation of the projector 100, and is a flowchart showing an adjustment process for adjusting the position of the projected image P by the position maintaining function. The adjustment process shown in can be executed by either the first projector 100A or the second projector 100B. In the following, the first projector 100A will be Adjustment process An example in which the adjustment is performed will be described below. Steps S41 to S46 are performed by processor 170A. That is, the adjustment process shown in FIG. 11 is performed by the adjustment function of processor 170A.

[0090] The control unit 150A causes the first camera 200A to perform shooting (step S41) and acquire a shot image. The control unit 150A detects feature points from the shot image (step S42). The feature points detected at this time include the feature points of the markers described above. The control unit 150A converts the coordinates of the feature points in the captured image into panel coordinates, which are coordinates on the liquid crystal panel 115A (step S43).

[0091] The control unit 150A compares the coordinates of the transformed feature point with the coordinates of the vertices of the drawing area 195 on the liquid crystal panel 115A (step S44). In step S44, for example, the control unit 150A calculates the difference between the coordinates of the feature point and the coordinates of the vertices of the drawing area 195.

[0092] The control unit 150A calculates a correction parameter for correcting the position of the drawing area 195 on the liquid crystal panel 115A (step S45). In step S45, the control unit 150A obtains a correction parameter for matching the position of the drawing area 195 to the position of the feature point based on, for example, the difference between the coordinates of the feature point and the coordinates of the vertices of the drawing area 195. The correction parameter is, for example, a projection transformation parameter for projecting the coordinates of the drawing area 195 into coordinates based on the feature point. By using this correction parameter, it is possible to convert not only the vertices of the drawing area 195 but also a plurality of coordinates included in the drawing area 195 into coordinates based on the feature point. The control unit 150A converts the coordinates of the drawing area 195 using the correction parameter, thereby correcting the position of the drawing area 195 on the liquid crystal panel 115A to a position based on the feature point (step S46).

[0093] Fig. 12 is an explanatory diagram of the adjustment process, showing the position of drawing area 195 on liquid crystal panel 115A. Fig. 12(a) shows the position of drawing area 195 on liquid crystal panel 115A before the adjustment process, etc. Fig. 12(b) shows the position of drawing area 195 on liquid crystal panel 115A after the adjustment process, etc.

[0094] In the example shown in Figures 12(a) and 12(b), an image formation area 193 arranged in an effective area 191 is made into an uneven rectangle by performing geometric correction. A drawing area 195 has a similar shape to the image formation area 193. In Figure 12(a), the drawing area 195 is located at the center of the image formation area 193. In other words, the drawing area 195 is arranged so that the center of gravity of the image formation area 193 and the center of gravity of the drawing area 195 coincide with each other. The area of ​​the drawing area 195 relative to the area of ​​the image formation area 193 is in accordance with a margin value.

[0095] 12(a) and 12(b), the coordinates of the feature points on the liquid crystal panel 115A are indicated by the symbol SP. In FIG. 12(a), the coordinates of the four vertices 196A, 196B, 196C, and 196D of the drawing area 195 and the coordinates of the four Feature points This indicates that the position of the first projected image PA has shifted from its initial position.

[0096] By the adjustment process shown in FIG. 11, the coordinates of the drawing area 195 are converted to coordinates that match the four coordinates SP. As a result, as shown in FIG. 12(b), the coordinates of the vertices 196A, 196B, 196C, and 196D match the four coordinates SP. On the screen SC, the image drawn in the drawing area 195 is displayed at the initial position determined by the initial setting in FIG. 4. According to this adjustment process, the position of the first projected image PA is adjusted to match the initial position by substantially moving the drawing area 195 on the liquid crystal panel 115A. Therefore, even if a factor occurs that causes the first projected image PA to deviate from the initial position, the projection position of the first projected image PA on the screen SC can be maintained.

[0097] In the example shown in FIG. 12(a) and FIG. 12(b), the image formation area 193 has a different shape from the effective area 191, but this is only one example. As shown in FIG. 12(a) and FIG. 12(b), when the image formation area 193 does not match the effective area 191, the margin value may be a value that makes the drawing area 195 smaller than the area of ​​the effective area 191. In this case, the area between the image formation area 193 and the effective area 191 can be used for drawing, so that the range in which the image can be moved can be widened by the position maintenance function. In other words, the area in the effective area 191 that is not the drawing area 195 can be used as an area in which the image is moved by the position maintenance function, that is, as a margin. In addition, it is of course possible to display the image so that the image formation area 193 matches the effective area 191, that is, the image formation area 193 is the entire effective area 191.

[0098] As described above, according to the display system 1 of this embodiment, when the position maintaining function is enabled, an image is projected in the image forming area 193 by using the drawing area 195 that is smaller than the area of ​​the image forming area 193. This allows the positions of the first projected image PA and the second projected image PB of the projector 100 to be maintained at their initial positions by converting the coordinates of the drawing area 195 in the liquid crystal panel 115A. Furthermore, when the position maintaining function is disabled, an image is projected by using the drawing area 195 in the liquid crystal panel 115A that has the same area as the area of ​​the image forming area 193. Therefore, a high-quality image can be projected onto the screen SC by using more pixels of the liquid crystal panel 115A.

[0099] [4. Other embodiments] The above-described embodiment is a preferred embodiment, however, the present invention is not limited to the above-described embodiment and various modifications are possible without departing from the spirit and scope of the present invention.

[0100] In the first embodiment, the display system 1 includes the first projector 100A and the second projector 100B, and performs tiling display by arranging the first projected image PA and the second projected image PB in the left-right direction, but the embodiment of the present disclosure is not limited to this. The display system 1 may perform tiling display by arranging the projected images of the multiple projectors 100 in the up-down direction. Furthermore, tiling display may be performed in the left-right direction or the up-down direction by three or more projectors 100. Two or more projectors 100 may perform so-called stacking display, in which the same image is superimposed and projected at the same position. In addition, the present disclosure may be applied to a configuration in which tiling display is not performed by one projector 100.

[0101] In the first embodiment, the configuration has been described in which the first projector 100A functions as a primary device, and the second projector 100B is a secondary device that operates according to the primary device. This is an example, and the control device 300 may execute the operations of, for example, FIG. 3, FIG. 4, and FIG. 11. In this case, the control device 300 executes control to cause the projector 100 to display the menu screen 500, the position setting screen 530, and the like, a process to accept a user's input to the projector 100, a process to transmit a margin value and a correction parameter to the projector 100, and the like. The control device 300 may perform a display equivalent to a margin display on a display provided in the control device 300. The control device 300 may cause the projector 100 to execute a margin display. In this case, the control device 300 corresponds to an example of an information processing device, and a program for the control device 300 to execute the operations of FIG. 3, FIG. 4, and FIG. 11 corresponds to an example of a program of the present disclosure.

[0102] In this embodiment, an example has been described in which the first projector 100A includes a transmissive liquid crystal panel 115A as a light modulation element, and the second projector 100B is configured in a similar manner, but the embodiment of the present disclosure is not limited to this. The light modulation element may be a reflective liquid crystal panel or a digital micromirror device. In addition, the number of light modulation elements is not limited to three, and may be one or more.

[0103] Also, Fig. 2 toEach of the functional units shown in the drawings indicates a functional configuration, and the specific implementation form is not particularly limited. In other words, it is not necessarily necessary to implement hardware corresponding to each functional unit individually, and it is of course possible to implement a configuration in which one processor executes a program to realize the functions of multiple functional units. Also, some of the functions realized by software in the above embodiment may be realized by hardware, or some of the functions realized by hardware may be realized by software. In addition, the specific detailed configurations of each of the other units of the projector 100 and the camera 200 can also be changed arbitrarily without departing from the spirit of the invention.

[0104] 5. Summary of this Disclosure The following is a summary of this disclosure. (Appendix 1) An information processing method including: receiving a first input indicating whether to disable or enable an adjustment function that aligns a position on a projection surface of a first projection image projected by a first projector to an initial position; when the first input indicating to disable the adjustment function is received, determining a drawing area, which is an area in which an image can be drawn on a display panel of the first projector, to a first area; and when the first input indicating to enable the adjustment function is received, determining the drawing area to a second area smaller than the first area.

[0105] According to this, when a first input indicating that the adjustment function is enabled is received, the adjustment function can be executed by determining the drawing area to be the second area. When a first input indicating that the adjustment function is disabled is received, a high-quality projection image can be projected by making the drawing area larger than the second area. Therefore, a projector having a projection image adjustment function can project a higher quality projection image.

[0106] (Appendix 2) The information processing method described in Appendix 1, further including, when the first input indicating enabling the adjustment function is received, receiving a second input indicating a size of the second area, and determining the drawing area to be the second area includes determining the size of the second area based on the second input.

[0107] According to this, the area to be drawn on the display panel when the adjustment function is enabled is determined based on the user's input, so that the balance between the quality of the projected image when using the adjustment function and the performance of the adjustment function can be determined according to the user's desire.
