[0009] The present embodiment will be described below with reference to the drawings. The image quality control system 100 according to the present embodiment includes an image quality control system 100A according to a first embodiment, which will be described with reference to Figures 1 to 6, an image quality control system 100B according to a second embodiment, which will be described mainly with reference to Figures 7 to 9, and an image quality control system 100C according to a third embodiment, which will be described mainly with reference to Figures 10 and 11.

[0010] [1. First embodiment] First, an image quality control system 100A according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of the image quality control system 100A according to the first embodiment. The image quality control system 100A includes a first projector 1A, a second projector 1B, and a server device 2.

[0011] Each of the first projector 1A and the second projector 1B projects projection light PL onto a screen SC, and displays a projection image PM on the screen SC. The second projector 1B is communicably connected to the server device 2 via a network NW. The network NW is, for example, the Internet.

[0012] The server device 2 includes a database DB that stores the first information QJ1 and the second information QJ2 in association with each other. The first information QJ1 indicates the image quality of the projected image PM projected by the first projector 1A. The second information QJ2 indicates the image quality corresponding to the first information QJ1 in the projected image PM projected by the second projector 1B. In other words, the second information QJ2 indicates the setting conditions for setting the second projector 1B so that the image quality of the projection image PM projected by the second projector 1B is close to the image quality of the projection image PM projected by the first projector 1A. The setting conditions include, for example, an image quality mode.

[0013] The second projector 1B acquires the first information QJ1 based on a user operation. The second projector 1B also acquires the second information QJ2 corresponding to the first information QJ1 from the server device 2. The second projector 1B also projects the projection image PM corresponding to the second information QJ2.

[0014] The first projector 1A corresponds to an example of a "first display device." The second projector 1B corresponds to an example of a "second display device." The first projector 1A corresponds to an example of an "other projector." The second projector 1B corresponds to an example of a "projector."

[0015] In the image quality control system 100A according to the first embodiment, the server device 2 is provided with the database DB, but the embodiment is not limited to this. It is sufficient that an information processing device configured to be able to communicate with the second projector 1B is provided with the database DB. The information processing device includes, for example, a personal computer, a tablet device, a smartphone, etc. In this case, the network NW may be, for example, a LAN (Local Area Network) or a WAN (Wide Area Network).

[0016] Next, the configuration of the projector 1 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configuration of the projector 1. The first projector 1A and the second projector 1B have approximately the same configuration, so in the following description, when there is no need to distinguish between the first projector 1A and the second projector 1B, each of the first projector 1A and the second projector 1B may be referred to as projector 1.

[0017] 2, the projector 1 includes a projection unit 110 and a drive unit 120 that drives the projection unit 110. The projection unit 110 forms an optical image and projects projection light PL onto a screen SC. In this embodiment, the projection unit 110 projects projection light PL corresponding to image data onto the screen SC in accordance with instructions from a first control unit 150. The projection unit 110 includes a light source unit 111, a light modulation device 112, and a projection optical system 113. The drive unit 120 includes a light source drive unit 121 and a light modulation device drive unit 122. The projection unit 110 corresponds to an example of an "optical device."

[0018] The light source unit 111 includes a solid-state light source such as an LED (Light Emitting Diode) or a laser light source. In this embodiment, the light source unit 111 is described as including a solid-state light source, but is not limited to this. Instead of the solid-state light source, the light source unit 111 may include a lamp light source such as a halogen lamp, a xenon lamp, or an ultra-high pressure mercury lamp. A solid-state light source or a lamp light source may be referred to as a light source in the following description.

[0019] The light source unit 111 may also include a reflector and an auxiliary reflector that guide the light emitted by the light source to the light modulation device 112. Furthermore, the light source unit 111 may also include a group of lenses for improving the optical characteristics of the projection light, a polarizing plate, or a dimming element that reduces the amount of light emitted by the light source on the path leading to the light modulation device 112. The light source driving unit 121 is connected to the internal bus 107, and controls the output of the light source by turning on and off the light source of the light source unit 111 in accordance with instructions from a first control unit 150 that is also connected to the internal bus 107. In this embodiment, the light source driving unit 121 controls the output of the light source in accordance with instructions from the first control unit 150.

[0020] The light modulation device 112 includes, for example, three liquid crystal panels 115 corresponding to the three primary colors of R, G, and B. R indicates red, G indicates green, and B indicates blue. That is, the light modulation device 112 includes a red liquid crystal panel corresponding to R light, a green liquid crystal panel corresponding to G light, and a blue liquid crystal panel corresponding to B light. The light emitted by the light source of the light source unit 111 is incident on the liquid crystal panel 115 .

[0021] Each of the three liquid crystal panels 115 is a transmissive liquid crystal panel that modulates light passing through it to generate projection light PL. The projection light PL includes red image light, green image light, and blue image light. The red image light is red image light that has been modulated after passing through a red liquid crystal panel. The green image light is green image light that has been modulated after passing through a green liquid crystal panel. The blue image light is blue image light that has been modulated after passing through a blue liquid crystal panel. The red image light, the green image light, and the blue image light are combined by a combining optical system such as a cross dichroic prism to generate the projection light PL, and the projection light PL is emitted to the projection optical system 113. In this embodiment, the light modulation device 112 is described as having a transmissive liquid crystal panel 115 as a light modulation element, but is not limited to this. The light modulation element may be a reflective liquid crystal panel or a digital micromirror device. The number of light modulation elements does not have to be three, and may be, for example, one.

[0022] The light modulation device 112 is driven by a light modulation device driving unit 122. The light modulation device driving unit 122 is connected to the image processing unit 145. Image data corresponding to each of the primary colors R, G, and B is input to the light modulation device driving unit 122 from the image processing unit 145. The light modulation device driving unit 122 converts the input image data into a data signal suitable for the operation of the liquid crystal panel 115. Based on the converted data signal, the light modulation device driving unit 122 applies a voltage to each pixel of each liquid crystal panel 115, and draws an image on each liquid crystal panel 115.

[0023] The projection optical system 113 includes a projection lens 113A that forms an image of the incident projection light PL on the screen SC, a mirror, etc. The projection optical system 113 also includes a zoom mechanism that enlarges or reduces the image projected onto the screen SC, a focus adjustment mechanism that adjusts the focus, and a lens shift mechanism that adjusts the projection direction of the projection light PL.

[0024] The projector 1 further includes an operation unit 131, a remote control receiver 133, an input interface 135, a storage unit 137, a first communication interface 141, a frame memory 143, an image processing unit 145, and a first control unit 150. The input interface 135, the storage unit 137, the first communication interface 141, the image processing unit 145, and the first control unit 150 are connected to each other via an internal bus 107 so as to be able to communicate data with each other.

[0025] The operation unit 131 includes various buttons and switches provided on the surface of the housing of the projector 1, generates operation signals corresponding to the operation of these buttons and switches, and outputs the operation signals to the input interface 135. The input interface 135 includes a circuit that outputs the operation signals input from the operation unit 131 to the first control unit 150.

[0026] The remote control light receiving unit 133 receives an infrared signal transmitted from the remote control 5, decodes the received infrared signal, and generates an operation signal. The remote control light receiving unit 133 outputs the generated operation signal to the input interface 135. The input interface 135 includes a circuit that outputs the operation signal input from the remote control light receiving unit 133 to the first control unit 150. The operation unit 131, the remote control 5, and the remote control light receiving unit 133 can also be said to be an input device.

[0027] The storage unit 137 is, for example, a magnetic recording device such as an HDD (Hard Disk Drive), or a storage device using a semiconductor storage element such as a flash memory or an SSD (Solid State Drive). The storage unit 137 stores programs executed by the first control unit 150, data processed by the first control unit 150, image data, etc.

[0028] The first communication interface 141 is a communication interface that communicates with the server device 2 in accordance with the Ethernet (registered trademark) standard. The first communication interface 141 includes a connector for connecting an Ethernet (registered trademark) cable and an interface circuit for processing signals transmitted through the connector. The first communication interface 141 is an interface board having a connector and an interface circuit, and is connected to a main board on which the first processor 150A and the like of the first control unit 150 are mounted. Alternatively, the connector and interface circuit that constitute the first communication interface 141 are mounted on the main board of the first control unit 150. The first communication interface 141 transmits first information QJ1 to the server device 2 and receives second information QJ2 from the server device 2.

[0029] The first control unit 150 includes a first memory 150B and a first processor 150A. The first memory 150B is a storage device that nonvolatilely stores programs and data executed by the first processor 150A. The first memory 150B is configured by a semiconductor storage element such as a magnetic storage device or a flash ROM (Read Only Memory), or other types of nonvolatile storage device. The first memory 150B may also include a RAM (Random Access Memory) that configures the work area of ​​the first processor 150A. The first memory 150B stores data processed by the first control unit 150, the first control program PG1 executed by the first processor 150A, and the like.

[0030] The first processor 150A may be configured as a single processor, or multiple processors may function as the first processor 150A. The first processor 150A executes a first control program PG1 to control each unit of the projector 1. For example, the first processor 150A outputs to the image processing unit 145 an instruction to execute image processing corresponding to operations received through the operation unit 131 and the remote control 5, and parameters used for this image processing. The parameters include, for example, geometric correction parameters for correcting geometric distortion of the image projected on the screen SC. The first processor 150A also controls the light source driving unit 121 to turn on and off the light source unit 111, and adjusts the output of the light source unit 111, i.e., the light intensity.

[0031] The first processor 150A may be configured as a system on chip (SoC) integrated with part or all of the first memory 150B and other circuits. The first processor 150A may also be configured as a combination of a central processing unit (CPU) that executes programs and a digital signal processor (DSP) that executes predetermined arithmetic processing. All of the functions of the first processor 150A may be implemented in hardware, or may be configured using a programmable device. The first processor 150A corresponds to an example of "at least one processor."

[0032] The image processing unit 145 and the frame memory 143 can be configured, for example, by an integrated circuit. Integrated circuits include large-scale integration (LSI), application-specific integrated circuits (ASIC), and programmable logic devices (PLD). PLDs include, for example, field-programmable gate arrays (FPGA). An integrated circuit may also include an analog circuit as part of its configuration, or may be a combination of a processor and an integrated circuit. The combination of a processor and an integrated circuit is called a microcontroller (MCU), a system-on-a-chip (SoC), a system LSI, a chipset, or the like.

[0033] The image processing unit 145 is configured, for example, by an integrated circuit. The image processing unit 145 expands the image data input from the first communication interface 141 into the frame memory 143. The frame memory 143 includes a plurality of banks. Each bank has a storage capacity capable of writing one frame's worth of image data. The frame memory 143 is configured, for example, by an SDRAM (Synchronous Dynamic Random Access Memory).

[0034] The image processing unit 145 performs image processing such as resolution conversion, resizing, distortion correction, shape correction, and digital zooming on the image data stored in the frame memory 143 . The image processing unit 145 also generates a vertical synchronization signal by converting the input frame frequency of the vertical synchronization signal into a drawing frequency. The generated vertical synchronization signal is called an output synchronization signal. The image processing unit 145 outputs the generated output synchronization signal to the light modulation device driving unit 122.

[0035] Next, the configuration of the first control unit 150 of the second projector 1B according to the first embodiment will be described with reference to Fig. 3. This figure shows an example of the configuration of the first control unit 150 of the second projector 1B.

[0036] In the following description, a case will be described in which the first processor 150A controls the image quality of the projection image PM projected by the second projector 1B by executing the first control program PG1. The first control program PG1 corresponds to an example of an "image quality control program."

[0037] The first control unit 150 includes a first acquisition unit 151, a second acquisition unit 152, a projection control unit 153, and an image quality storage unit 154. Specifically, the first processor 150A of the first control unit 150 executes the first control program PG1 stored in the first memory 150B, thereby functioning as a first acquisition unit 151, a second acquisition unit 152, and a projection control unit 153. Furthermore, the first processor 150A of the first control unit 150 executes the first control program PG1 stored in the first memory 150B, thereby causing the first memory 150B to function as an image quality storage unit 154.

[0038] The image quality storage unit 154 stores the first information QJ1 and the second information QJ2. The image quality is the visual quality of the image. The image quality is expressed by, for example, but not limited to, brightness, color, contrast, and resolution. The first information QJ1 indicates the image quality of the first projected image PM1 projected by the first projector 1 A. The first projector 1 A displays the first projected image PM1 on the first screen SC1 based on the first information QJ1. The first information QJ1 is information related to setting values ​​that control the image quality of the first projector 1A. The first information QJ1 may be represented by one or more setting values, or may be information that indirectly represents image quality, such as information about a mode related to image quality, or may be a combination of these. The first information QJ1 may include setting values ​​that are preset in the first projector 1A, or may include setting values ​​that are set by the user. In this embodiment, the first information QJ1 includes information indicating a first image quality mode QM1 that controls the image quality of the first projector 1A. The first image quality mode QM1 is defined by a plurality of setting values ​​that are preset in the first projector 1A. By using information indicating the first image quality mode QM1 as the first information QJ1, the data structure of the database DB, which will be described later, can be simplified compared to when the first information QJ1 is represented by a plurality of setting values. Note that in this embodiment, because the first image quality mode QM1 is defined by preset setting values, there are fewer combinations of setting values ​​that need to be considered in the database DB compared to when the user can change the setting values, and therefore the data structure of the database DB can be simplified.

[0039] The second information QJ2 indicates the image quality of the second projected image PM2 projected by the second projector 1B. The second information QJ2 indicates the image quality of the second projected image PM2 projected by the second projector 1B, corresponding to the first information QJ1. The second projector 1B displays the second projected image PM2 on the second screen SC2 based on the second information QJ2. The second information QJ2 includes information indicating a second image quality mode QM2 that controls the image quality of the second projector 1B. The second image quality mode QM2 is defined by a plurality of setting values ​​preset in the second projector 1B.

[0040] The first projected image PM1 corresponds to an example of the projected image PM. The second projected image PM2 corresponds to an example of the projected image PM. The second projected image PM2 may be the same image as the first projected image PM1, or may be an image different from the first projected image PM1. The first projected image PM1 corresponds to an example of a "first image." The second projected image PM2 corresponds to an example of a "second image."

[0041] The first screen SC1 corresponds to an example of a screen SC. The second screen SC2 corresponds to an example of a screen SC. The second screen SC2 may be the same screen SC as the first screen SC1, or may be a screen SC different from the first screen SC1. In other words, the first projector 1A and the second projector 1B may perform so-called "stacking" projection, in which the same image is superimposed and projected at the same position, or may perform so-called "tiling" projection, in which two images are linked together to project a single image as a whole. The first projector 1A and the second projector 1B may also project different images onto different screens SC. The present disclosure is particularly suitable for use in a usage environment in which both the first projected image PM1 and the second projected image PM2 are visible to the user, such as the same space. The first information QJ1 and the second information QJ2 will be further described with reference to FIG.

[0042] The first information QJ1 is acquired by the first acquisition unit 151 and stored in the image quality storage unit 154 by the first acquisition unit 151. The second information QJ2 is acquired by the second acquisition unit 152 and stored in the image quality storage unit 154 by the second acquisition unit 152.

[0043] The first acquisition unit 151 acquires the first information QJ1 based on a user operation. The first acquisition unit 151 acquires the first information QJ1 based on, for example, a user operation on the operation unit 131. The first acquisition unit 151 stores the acquired first information QJ1 in the image quality storage unit 154. The processing of the first acquisition unit 151 will be further described with reference to FIG.

[0044] The second acquisition unit 152 acquires the second information QJ2 from the database DB of the server device 2. First, the second acquisition unit 152 transmits, for example, the first information QJ1 to the server device 2. Next, the server device 2 reads out the second information QJ2 corresponding to the first information QJ1 from the database DB. Next, the server device 2 transmits the read out second information QJ2 to the second projector 1B. Next, the second acquisition unit 152 acquires the second information QJ2 by ​​receiving it from the server device 2. Furthermore, the second acquisition unit 152 stores the acquired second information QJ2 in the image quality storage unit 154.

[0045] In addition, when the server device 2 receives the first information QJ1 from the second projector 1B, it reads out the second information QJ2 corresponding to the first information QJ1 from the database DB and transmits the second information QJ2 to the second projector 1B.

[0046] The projection control unit 153 sets the second information QJ2 in the second projector 1B. That is, the projection control unit 153 applies setting values ​​corresponding to the second information QJ2 to the second projector 1B as setting values ​​to be used for projection. The projection control unit 153 also causes the second projector 1B to project projection light PL corresponding to the second projection image PM2 onto the second screen SC2, and display the second projection image PM2 on the second screen SC2.

[0047] Next, the configuration of the database DB will be described with reference to Fig. 4. Fig. 4 is a table showing an example of the configuration of the database DB. The first information QJ1 and the second information QJ2 are associated with each other in a table format in Fig. 4. As shown in Fig. 4, the first information QJ1 includes first manufacturer information MN1 indicating the manufacturer of the first projector 1A, first model information MD1 indicating the model of the first projector 1A, and a first image quality mode QM1. The first manufacturer information MN1 corresponds to an example of "manufacturer information." The first model information MD1 corresponds to an example of "model information."

[0048] The first manufacturer information MN1 includes, for example, "Company A" and "Company B." If the first manufacturer information MN1 is, for example, "Company A," the first model information MD1 includes "AA-00" and "AA-22." If the first model information MD1 is "AA-00," the first image quality mode QM1 includes "Dynamic Mode," "Cinema Mode," and "Natural Mode."

[0049] If the first manufacturer information MN1 is "Company A", the first model information MD1 is "AA-00", and the first image quality mode QM1 is "dynamic mode", the second image quality mode QM2 of the second information QJ2 corresponding to the first image quality mode QM1 is "dynamic mode". Furthermore, if the first manufacturer information MN1 is "Company A," the first model information MD1 is "AA-00," and the first image quality mode QM1 is "Cinema mode," the second image quality mode QM2 of the second information QJ2 corresponding to the first image quality mode QM1 is "Cinema 1 mode." Furthermore, if the first manufacturer information MN1 is "Company A," the first model information MD1 is "AA-00," and the first image quality mode QM1 is "Natural Mode," the second image quality mode QM2 of the second information QJ2 corresponding to the first image quality mode QM1 is "Living Mode."

[0050] The second image quality mode QM2 also defines the brightness BR2 and color CL2 of the second projected image PM2. When the second image quality mode QM2 is the "Dynamic Mode," the brightness BR2 of the second projected image PM2 is set to "50," and the color CL2 of the second projected image PM2 is set to "60." When the second image quality mode QM2 is the "Cinema 1 Mode," the brightness BR2 of the second projected image PM2 is set to "60," and the color CL2 of the second projected image PM2 is set to "40." When the second image quality mode QM2 is the "Living Room Mode," the brightness BR2 of the second projected image PM2 is set to "45," and the color CL2 of the second projected image PM2 is set to "50." The setting value of the second image quality mode QM2 may be a value preset in the second projector 1B, or may be a value specified in the database DB that is different from the preset. If the setting value is a preset value, the description of the setting value in the database DB can be omitted, thereby simplifying the database DB. If a value different from the preset is included, the image quality of the second projected image PM2 can be made closer to the image quality of the first projected image PM1. The brightness BR2 and the hue CL2 correspond to an example of "plurality of setting values."

[0051] Next, the processing of the first acquisition unit 151 will be further described with reference to Fig. 5. Fig. 5 is a screen diagram showing an example of a user input screen 500. The input screen 500 is projected by the first acquisition unit 151, for example, from the second projector 1B onto the second screen SC2. The user performs an input operation on the input screen 500 by operating, for example, the remote control 5 or operation unit 131 of the second projector 1B. Note that the input screen 500 may be displayed by the first acquisition unit 151 on an LCD (Liquid Crystal Display) arranged on a touch panel of the operation unit 131. 5 shows a first input screen 510 and a second input screen 520 after each item on the first input screen 510 has been entered by a user operation. The first input screen 510 and the second input screen 520 correspond to an example of the input screen 500. The first input screen 510 is the input screen 500 before accepting a user operation. The user enters each item on the input screen 500 by checking the product information written on the main body of the first projector 1A and the menu screen of the first projector 1A.

[0052] Each of the first input screen 510 and the second input screen 520 includes a first input section E1, a second input section E2, a third input section E3, an OK button BY, and a cancel button BN. The first input unit E1 accepts the first manufacturer information MN1 based on a user operation. When a touch operation is accepted on the "Please select. ▼" field displayed in the first input unit E1 of the first input screen 510, the first acquisition unit 151 displays a list of the first manufacturer information MN1 as a pull-down menu. Then, when a touch operation is accepted to select one piece of first manufacturer information MN1 from the displayed list of first manufacturer information MN1, the first acquisition unit 151 displays the selected first manufacturer information MN1.

[0053] The second input unit E2 accepts the first model information MD1 based on a user operation. When a touch operation is accepted on the "Please select. ▼" field displayed in the second input unit E2 of the first input screen 510, the first acquisition unit 151 displays a list of the first model information MD1 as a pull-down menu. Note that the list of first model information MD1 is a list of first model information MD1 manufactured by the first manufacturer information MN1 selected in the first input unit E1. Then, when a touch operation is accepted to select one piece of first model information MD1 from the displayed list of first model information MD1, the first acquisition unit 151 displays the selected first model information MD1.

[0054] The third input unit E3 accepts the first image quality mode QM1 based on a user operation. When a touch operation is accepted on the "Please select. ▼" column displayed in the third input unit E3 of the first input screen 510, the first acquisition unit 151 displays a list of the first image quality modes QM1 as a pull-down menu. The list of first image quality modes QM1 is a list of multiple first image quality modes QM1 included in the first model information MD1 selected in the second input unit E2. Then, when a touch operation is accepted to select one first image quality mode QM1 from the list of multiple first image quality modes QM1 displayed, the first acquisition unit 151 displays the selected first image quality mode QM1. When the first image quality mode QM1 is limited to modes defined by preset setting values, it is preferable that the third input unit E3 not display, as options, image quality modes whose setting values ​​are changeable by the user. This makes it possible to inform the user that the image quality mode of the first projector 1A must be set to a mode defined by preset setting values, even if the first projector 1A has an image quality mode whose setting values ​​are changeable by the user, such as a "user setting" mode. The multiple first image quality modes QM1 correspond to an example of "multiple candidates for first information."

[0055] As described above, the first acquisition unit 151 accepts the operation of sequentially selecting the first manufacturer information MN1, the first model information MD1, and the first image quality mode QM1, thereby accepting the first image quality mode QM1. Then, the first acquisition unit 151 projects the second input screen 520 shown in FIG. 5 onto the second screen SC2 via, for example, the second projector 1B. The user operates, for example, the remote control 5 or the operation unit 131 of the second projector 1B to perform an input operation on the input screen 500. Note that the first acquisition unit 151 may display the input screen 500 on an LCD arranged on a touch panel of the operation unit 131.

[0056] On the second input screen 520, for example, "Company A" is displayed in the first input section E1, "AA-00" is displayed in the second input section E2, and "Cinema" is displayed in the third input section E3. Second input screen 520 indicates that the following selection operations have been received: First, "Company A" has been selected from the list of first manufacturer information MN1 displayed in first input section E1 of first input screen 510. Next, "AA-00" has been selected from the list of first model information MD1 displayed in second input section E2 of first input screen 510. Next, "Cinema" has been selected from the list of first image quality modes QM1 displayed in third input section E3 of first input screen 510.

[0057] The OK button BY is a button that is touched by the user to confirm the selection operation, and the cancel button BN is a button that is touched by the user to cancel the selection operation.

[0058] In this way, the user can easily select the first image quality mode QM1 as shown on the second input screen 520 by inputting a selection operation on the first input screen 510.

[0059] Next, the processing of the first control unit 150 of the second projector 1B will be described with reference to Fig. 6. Fig. 6 is a flowchart showing an example of the processing of the first control unit 150 of the second projector 1B. As shown in FIG. 6, in step S101, the first acquisition unit 151 acquires first information QJ1 based on a user operation. Next, in step S103, the second acquisition unit 152 acquires the second information QJ2 from the database DB. First, the second acquisition unit 152 transmits the first information QJ1 to, for example, the server device 2. Next, the server device 2 reads out the second information QJ2 corresponding to the first information QJ1 from the database DB. Next, the server device 2 transmits the read out second information QJ2 to the second projector 1B. Next, the second acquisition unit 152 acquires the second information QJ2 from the server device 2.

[0060] Next, in step S105, the projection control section 153 sets the second information QJ2 in the second projector 1B. Next, in step S107, the projection control section 153 causes the second projector 1B to project the projection light PL corresponding to the second projection image PM2 onto the second screen SC2, and causes the second projection image PM2 to be displayed on the second screen SC2. Next, in step S109, the first control unit 150 determines whether or not to end the projection of the second projector 1B. If the first control unit 150 determines not to end the projection of the second projector 1B (step S109; NO), the process returns to step S107. If the first control unit 150 determines that the projection of the second projector 1B will end (step S109; YES), the process then ends.

[0061] [2. Second Embodiment] Next, an image quality control system 100B according to the second embodiment will be described, mainly with reference to Figures 7 to 9. In the following explanation, differences between the image quality control system 100B according to the second embodiment and the image quality control system 100A according to the first embodiment will be mainly described, and the same components as those in the image quality control system 100A according to the first embodiment will be assigned the same reference numerals as in the first embodiment, and explanations thereof will be omitted.

[0062] First, the configuration of an image quality control system 100B according to the second embodiment will be described with reference to Fig. 7. Fig. 7 is a diagram showing an example of the configuration of an image quality control system 100B according to the second embodiment. As shown in FIG. 7, the image quality control system 100B differs from the image quality control system 100A according to the first embodiment in that it includes a smartphone 3A. The smartphone 3A is communicably connected to the server device 2 via the network NW. The smartphone 3A is also communicably connected to the second projector 1B via wireless communication such as Wi-Fi (registered trademark).

[0063] The smartphone 3A acquires first information QJ1 based on a user operation. The smartphone 3A also acquires second information QJ2 corresponding to the first information QJ1 from the server device 2. The smartphone 3A also causes the second projector 1B to project a projection image PM corresponding to the second information QJ2.

[0064] In other words, in the image quality control system 100A according to the first embodiment, the smartphone 3A has the functions of the first control unit 150 of the second projector 1B. The functions of the smartphone 3A will be further described with reference to FIG. 8. The configuration of each of the first projector 1A and the second projector 1B is the same as the configuration of the projector 1 described with reference to FIG.

[0065] Next, the configuration of the smartphone 3A will be described with reference to Fig. 8. Fig. 8 is a diagram showing an example of the configuration of the third control unit 30 of the smartphone 3A. As shown in FIG. 8, the smartphone 3A includes a third control unit 30 and a touch panel 33.

[0066] The third control unit 30 includes a third processor 31 and a third memory 32 . The third memory 32 is a storage device that non-volatilely stores programs and data executed by the third processor 31. The third memory 32 is configured by a magnetic storage device, a semiconductor storage element such as a flash ROM, or other types of non-volatile storage device. The third memory 32 may also include RAM that configures the work area of ​​the third processor 31. The third memory 32 stores data processed by the third control unit 30, the third control program PG3 executed by the third processor 31, and the like.

[0067] The third processor 31 may be configured as a single processor, or may be configured such that multiple processors function as the third processor 31. The third processor 31 executes the first control program to control each part of the smartphone 3A. For example, the third processor 31 causes each part of the smartphone 3A to execute a process corresponding to an operation received via the touch panel 33.

[0068] The third processor 31 may be configured as an SoC integrated with part or all of the third memory 32 and other circuits. The third processor 31 may also be configured as a combination of a CPU that executes programs and a DSP that executes predetermined arithmetic processing. All of the functions of the third processor 31 may be implemented in hardware, or may be configured using a programmable device.

[0069] The touch panel 33 includes a display such as an LCD and a touch sensor. The touch sensor is disposed on the surface of the LCD, for example, and receives touch operations from the user. The touch sensor also outputs a signal indicating the received touch operation to the third control unit 30.

[0070] The third control unit 30 includes a first acquisition unit 311, a second acquisition unit 312, a projection control unit 313, and an image quality storage unit 321. Specifically, the third processor 31 of the third control unit 30 executes the third control program PG3 stored in the third memory 32, thereby functioning as a first acquisition unit 311, a second acquisition unit 312, and a projection control unit 313. Furthermore, the third processor 31 of the third control unit 30 executes the third control program PG3 stored in the third memory 32, thereby causing the third memory 32 to function as an image quality storage unit 321. The third processor 31 corresponds to an example of a "processor." The third control program PG3 corresponds to an example of an "image quality control program."

[0071] The image quality storage unit 321 stores the first information QJ1 and the second information QJ2. The first information QJ1 is acquired by the first acquisition unit 311 and stored in the image quality storage unit 321 by the first acquisition unit 311. The second information QJ2 is acquired by the second acquisition unit 312 and stored in the image quality storage unit 321 by the second acquisition unit 312.

[0072] The first acquisition unit 311 acquires the first information QJ1 based on a user operation. The first acquisition unit 311 acquires the first information QJ1 based on, for example, a user operation on the touch panel 33. The first acquisition unit 311 stores the acquired first information QJ1 in the image quality storage unit 321.

[0073] 5, the first acquisition unit 311 displays the first input screen 510 on the touch panel 33. Then, the first acquisition unit 311 accepts operations on the first input section E1, the second input section E2, and the third input section E3 of the first input screen 510, and accepts the first manufacturer information MN1, the first model information MD1, and the first image quality mode QM1. In addition, the first acquisition unit 311 displays the second input screen 520 on the touch panel 33.

[0074] The second acquisition unit 312 acquires the second information QJ2 from the database DB of the server device 2. The database DB has the configuration described with reference to FIG. First, the second acquisition unit 312 transmits the first information QJ1 to the server device 2, for example. Next, the server device 2 reads out the second information QJ2 corresponding to the first information QJ1 from the database DB. Next, the server device 2 transmits the read out second information QJ2 to the smartphone 3. Next, the second acquisition unit 312 acquires the second information QJ2 by ​​receiving it from the server device 2. Furthermore, the second acquisition unit 312 stores the acquired second information QJ2 in the image quality storage unit 321.

[0075] In addition, when the server device 2 receives the first information QJ1 from the smartphone 3, it reads out the second information QJ2 corresponding to the first information QJ1 from the database DB and transmits the second information QJ2 to the smartphone 3.

[0076] The projection control section 313 sets the second information QJ2 in the second projector 1B. For example, the projection control section 313 first transmits the second information QJ2 to the second projector 1B. The second projector 1B has a second communication interface not shown in Fig. 2. The second communication interface is a communication interface that executes communication with the smartphone 3A in accordance with the Wi-Fi (registered trademark) standard. The second communication interface of the second projector 1B receives the second information QJ2. Then, the first control unit 150 of the second projector 1B acquires the second information QJ2. Next, the first control unit 150 of the second projector 1B sets the second information QJ2.

[0077] Furthermore, the projection control section 313 causes the second projector 1B to project the projection light PL corresponding to the second projection image PM2 onto the second screen SC2, and causes the second projection image PM2 to be displayed on the second screen SC2.

[0078] The processing of the third control unit 30 of the smartphone 3A in the image quality control system 100B according to the second embodiment is substantially the same as the processing of the first control unit 150 of the second projector 1B described with reference to FIG. 6 in the image quality control system 100A according to the first embodiment.

[0079] Specifically, the processing of the first acquisition unit 151 of the first control unit 150 of the second projector 1B in step S101 of Fig. 6 is executed by the first acquisition unit 311 of the third control unit 30 of the smartphone 3A. Moreover, the processing of the second acquisition unit 152 of the first control unit 150 of the second projector 1B in step S103 of Fig. 6 is executed by the second acquisition unit 312 of the third control unit 30 of the smartphone 3A. Moreover, the processing of the projection control unit 153 of the first control unit 150 of the second projector 1B in steps S105 and S107 of Fig. 6 is executed by the projection control unit 313 of the third control unit 30 of the smartphone 3A. Moreover, the processing of the first control unit 150 of the second projector 1B in step S109 of Fig. 6 is executed by the third control unit 30 of the smartphone 3A.

[0080] 3. Modification of the Second Embodiment Next, a modified example of the image quality control system 100B according to the second embodiment will be described with reference to Fig. 9. Fig. 9 is a screen diagram showing an example of a display screen 600 of the first projector 1A. In the following explanation, the modified form of the image quality control system 100B according to the second embodiment will mainly be explained in terms of the differences from the image quality control system 100B according to the second embodiment, and the same configurations as those of the image quality control system 100B according to the second embodiment will be given the same symbols as in the second embodiment, and their explanation will be omitted.

[0081] As described with reference to Fig. 8, in the image quality control system 100B according to the second embodiment, the first acquisition unit 311 displays the first input screen 510 on the touch panel 33, for example, as described with reference to Fig. 5. Then, the first acquisition unit 311 accepts operations on the first input section E1, the second input section E2, and the third input section E3 of the first input screen 510, and accepts the first manufacturer information MN1, the first model information MD1, and the first image quality mode QM1.

[0082] In contrast, in a modified form of the image quality control system 100B according to the second embodiment, the first acquisition unit 311 accepts, for example, first manufacturer information MN1, first model information MD1, and first image quality mode QM1 based on a captured image of the display screen 600 of the first projector 1A. The display screen 600 shows, for example, the menu screen of the first projector 1A.

[0083] 9, the display screen 600 has an image quality mode display section 610. In the image quality mode display section 610, for example, "presentation mode" is set as the first image quality mode QM1.

[0084] That is, first, the user causes a menu screen to be displayed on the LCD of the operation unit 131 of the first projector 1A. Then, the first acquisition unit 311 causes a camera (not shown) of the smartphone 3A to capture an image of the menu screen and acquires a captured image of the display screen 600. The first acquisition unit 311 also performs character recognition processing on the captured image of the display screen 600 and accepts that the first image quality mode QM1 is "presentation mode." In this way, the first acquisition unit 311 accepts the first image quality mode QM1 based on the captured image of the display screen 600 of the first projector 1A.

[0085] In Figure 9, we have explained the case where the first acquisition unit 311 accepts the first image quality mode QM1 based on the captured image of the display screen 600 of the first projector 1A, but in a similar manner, the first acquisition unit 311 acquires the first manufacturer information MN1 and the first model information MD1 based on the captured image of the first projector 1A.

[0086] Furthermore, the first acquisition unit 311 causes, for example, a camera (not shown) included in the smartphone 3A to capture an image of a model number display panel disposed on the rear surface or the like of the main body of the first projector 1A, and acquires the captured image of the model number display panel. Then, the first acquisition unit 311 performs character recognition processing on the captured image of the model number display panel, and acquires the first manufacturer information MN1 and first model information MD1 of the first projector 1A.

[0087] In this way, the first acquisition unit 311 receives the first manufacturer information MN1, the first model information MD1, and the first image quality mode QM1 based on the captured image of the first projector 1 A. Therefore, compared to the image quality control system 100B according to the second embodiment, the burden on the user when acquiring the first manufacturer information MN1, the first model information MD1, and the first image quality mode QM1 can be reduced.

[0088] 4. Third Embodiment Next, an image quality control system 100C according to the third embodiment will be described, mainly with reference to Figures 10 and 11. In the following explanation, differences between the image quality control system 100C according to the third embodiment and the image quality control system 100B according to the second embodiment will be mainly described, and the same components as those in the image quality control system 100B according to the second embodiment will be assigned the same reference numerals as in the second embodiment, and the explanation thereof will be omitted.

[0089] First, the configuration of an image quality control system 100C according to the third embodiment will be described with reference to Fig. 10. Fig. 10 is a diagram showing an example of the configuration of an image quality control system 100C according to the third embodiment. 10, the image quality control system 100C differs from the image quality control system 100B according to the second embodiment in that the smartphone 3B includes a database DB. Furthermore, because the smartphone 3B includes a database DB, the image quality control system 100C does not need to communicate with the server device 2 each time. In other words, the image quality control system 100C does not need to include the server device 2.

[0090] The smartphone 3B is communicably connected to the second projector 1B via wireless communication such as Wi-Fi (registered trademark). The smartphone 3B acquires first information QJ1 based on a user operation. The smartphone 3A also acquires second information QJ2 corresponding to the first information QJ1 from the database DB. The smartphone 3A also causes the second projector 1B to project a projection image PM corresponding to the second information QJ2.

[0091] Next, the configuration of the smartphone 3B will be described with reference to Fig. 11. Fig. 11 is a diagram showing an example of the configuration of the third control unit 30 of the smartphone 3B. As shown in FIG. 11, the smartphone 3B includes a third control unit 30 and a touch panel 33.

[0092] The third control unit 30 includes a first acquisition unit 311, a second acquisition unit 312, a projection control unit 313, an image quality storage unit 321, and a database DB. Specifically, the third processor 31 of the third control unit 30 executes the fourth control program PG4 stored in the third memory 32, thereby functioning as a first acquisition unit 311, a second acquisition unit 312, and a projection control unit 313. Furthermore, the third processor 31 of the third control unit 30 executes the fourth control program PG4 stored in the third memory 32, thereby causing the third memory 32 to function as an image quality storage unit 321 and a database DB. The third processor 31 corresponds to an example of a "processor." The fourth control program PG4 corresponds to an example of an "image quality control program."

[0093] The image quality storage unit 321 stores the first information QJ1 and the second information QJ2. The database DB stores the first information QJ1 and the second information QJ2 in association with each other. The database DB has the configuration described with reference to FIG.

[0094] The function of the first acquisition section 311 is the same as the function of the first acquisition section 311 of the smartphone 3A of the image quality control system 100B according to the second embodiment described with reference to FIG. The function of the projection control section 313 is the same as the function of the projection control section 313 of the smartphone 3A of the image quality control system 100B according to the second embodiment described with reference to FIG.

[0095] The second acquisition unit 312 acquires the second information QJ2 from the database DB. First, the second acquisition unit 312 acquires the second information QJ2 by, for example, reading out from the database DB the second information QJ2 corresponding to the first information QJ1 acquired by the first acquisition unit 311. The second acquisition unit 312 also stores the acquired second information QJ2 in the image quality storage unit 321.

[0096] The processing of the third control unit 30 of the smartphone 3B in the image quality control system 100C of the third embodiment is substantially the same as the processing of the third control unit 30 of the smartphone 3A described with reference to Figure 6 in the image quality control system 100B of the second embodiment. However, the process corresponding to step S103 in FIG. 6 is different, and will be explained below.

[0097] 6, the second acquisition unit 152 acquires the second information QJ2 from the database DB. For example, the second acquisition unit 152 acquires the second information QJ2 by ​​reading the second information QJ2 corresponding to the first information QJ1 acquired by the first acquisition unit 311 from the database DB.

[0098] As explained with reference to Figures 10-11, in the image quality control system 100C according to the third embodiment, the smartphone 3B is equipped with a database DB, and therefore the second acquisition unit 152 can acquire the second information QJ2 corresponding to the first information QJ1 through simple processing.

[0099] [5. This embodiment and its effects] As described above with reference to Figures 1 to 11, the image quality control method includes acquiring first information QJ1 indicating the image quality of a first projector 1A, acquiring second information QJ2 indicating the image quality corresponding to the first information QJ1 of a second projector 1B different from the first projector 1A from a database DB that stores the first information QJ1 and the second information QJ2 in association with each other, and setting the second information QJ2 to the second projector 1B.

[0100] Therefore, by setting the second information QJ2 indicating the image quality of the second projector 1B corresponding to the image quality of the first projector 1A in the second projector 1B, the image quality of the second projector 1B can be set to an image quality that is close to the image quality of the first projector 1A.

[0101] The image quality control method further includes the first projector 1A displaying a first projected image PM1 based on the first information QJ1, and the second projector 1B displaying a second projected image PM2 based on the second information QJ2. Therefore, the second projected image PM2 projected by the second projector 1B can be displayed with image quality similar to that of the first projected image PM1 projected by the first projector 1A.

[0102] Furthermore, in the image quality control method, the first information QJ1 includes information indicating a first image quality mode QM1 that controls the image quality of the first projector 1A. Therefore, by causing the first projector 1A to project in the first image quality mode QM1, the first projector 1A can project with the image quality indicated by the first information QJ1. Furthermore, compared to when the first information QJ1 is expressed as multiple setting values ​​indicating the image quality of the first projector 1A, the database DB indicating the correspondence with the second information QJ2 can be simplified.

[0103] In the image quality control method, the first image quality mode QM1 is defined by a plurality of setting values ​​preset in the first projector 1A. Therefore, by defining setting values ​​that define image quality such as brightness and color tone as the plurality of setting values, the first projector 1A can project with the image quality indicated by the first image quality mode QM1.

[0104] Furthermore, in the image quality control method, acquiring the first information QJ1 includes acquiring the first information QJ1 based on a captured image that captures an image including the first information QJ1 to be displayed by the first projector 1A. Therefore, since the first information QJ1 is obtained based on a captured image of an image including the first information QJ1 to be displayed by the first projector 1A, the first information QJ1 can be obtained more easily than when the user manually inputs the first information QJ1.

[0105] In the image quality control method, acquiring the first information QJ1 includes acquiring the first information QJ1 based on a user operation. Therefore, since the first information QJ1 is acquired based on the user's operation, the first information QJ1 can be acquired with a simple configuration.

[0106] In addition, in the image quality control method, acquiring the first information QJ1 includes acquiring first manufacturer information MN1 and first model information MD1 of the first projector 1A based on user operation, displaying a plurality of first image quality modes QM1 selectable based on the first manufacturer information MN1 and the first model information MD1, and acquiring the first image quality mode QM1 from the plurality of first image quality modes QM1 based on user operation. Therefore, the first image quality mode QM1 of the first projector 1A is obtained based on a user's operation on a plurality of first image quality modes QM1 displayed to be selectable, and therefore the first information QJ1 can be obtained easily with a simple configuration.

[0107] In the image quality control method, the first information QJ1 includes first model information MD1 that indicates the model of the first projector 1A. Therefore, to obtain the first model information MD1, the first information QJ1 of the first projector 1A can be obtained by selecting one piece of first information QJ1 from multiple pieces of first information QJ1 that can be executed by the model indicated by the first model information MD1.

[0108] The first control program PG1 of this embodiment executes the following: the first processor 150A acquires first information QJ1 indicating the image quality of the first projector 1A; acquires second information QJ2 indicating the image quality corresponding to the first information QJ1 of a second projector 1B different from the first projector 1A from a database DB that stores the first information QJ1 and the second information QJ2 in association with each other; and sets the second information QJ2 to the second projector 1B. Therefore, the first control program PG1 according to this embodiment has the same configuration as the image quality control method for the projector 1 according to this embodiment, and therefore provides the same effects as the image quality control method for the projector 1 according to this embodiment.

[0109] The second projector 1B in this embodiment includes a projection unit 110 that projects a projection image, and a first processor 150A that performs the following operations: acquiring first information QJ1 indicating the image quality of the first projection image PM1 of the first projector 1A; acquiring second information QJ2 indicating the image quality corresponding to the first information QJ1 of a second projector 1B that is different from the first projector 1A from a database DB that stores the first information QJ1 and the second information QJ2 in association with each other; and having the second projector 1B project the second projection image PM2 with the image quality corresponding to the second information QJ2. Therefore, by using the second information QJ2 indicating the image quality of the second projector 1B corresponding to the image quality of the first projector 1A, the second projected image PM2 projected by the second projector 1B can be projected with image quality that is close to the image quality of the first projected image PM1 projected by the first projector 1A.

[0110] 6. Other Embodiments The above-described embodiment is a preferred embodiment, but is not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the present invention.

[0111] In this embodiment, the case where each of the "first display device" and the "second display device" is the projector 1 has been described, but the embodiment is not limited to this. Each of the "first display device" and the "second display device" may be, for example, a display such as an LCD.

[0112] In the image quality control system 100B according to the second embodiment and the image quality control system 100C according to the third embodiment, the smartphone 3 has been described as having the first acquisition unit 311, the second acquisition unit 312, and the projection control unit 313, but the embodiments are not limited to this. Any information processing device may have the first acquisition unit 311, the second acquisition unit 312, and the projection control unit 313. The information processing device may be, for example, a personal computer or a tablet computer.

[0113] 2, 3, 8, and 11 show functional configurations, and the specific implementation form is not particularly limited. In other words, it is not necessary to implement hardware corresponding to each functional unit individually, and a configuration in which a single processor executes a program to realize the functions of multiple functional units is also possible. Also, some of the functions realized by software in the above embodiments 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 unit of the projector 1 and the smartphone 3 may be changed as desired without departing from the spirit of the invention.

[0114] 6 is divided according to the main processing content in order to make it easier to understand the processing of first control unit 150 of second projector 1B. There is no limitation to the division method or names of the processing units shown in the flowchart of FIG. 6, and the processing can be divided into more processing units according to the processing content, or one processing unit can be divided so as to include more processes. Furthermore, the processing order of the above flowchart is not limited to the example shown in the figure.

[0115] Furthermore, the image quality control method of the projector 1 can be realized by having the first processor 150A of the first control unit 150 of the second projector 1B execute a first control program PG1 corresponding to the image projection method of the projector 1.
