The first memory 120 may also have a volatile storage area and constitute a work area that temporarily stores programs executed by the first processor 110 and data to be processed.

[0019] The first memory 120 stores setting data 122 in addition to the control program 121 executed by the first processor 110.

[0020] The projector 1 includes a first interface 11, a second interface 12, a frame memory 13, an image processing unit 14, and an operation unit 15. Each of these units is connected to a first control unit 10 via a bus 19 so as to be able to communicate data with the first control unit 10.

[0021] The first interface 11 includes communication hardware such as a connector and an interface circuit that conforms to a predetermined communication standard.

[0023] The frame memory 13 and the image processing unit 14 are configured, for example, by integrated circuits. Examples of integrated circuits include LSI, ASIC (Application Specific Integrated Circuit), PLD (Programmable Logic Device), FPGA (Field-Programmable Gate Array), SoC (System-on-a-chip), etc. An analog circuit may be included as part of the integrated circuit configuration, or the first control unit 10 may be configured in combination with an integrated circuit.

[0024] The frame memory 13 includes a plurality of banks. Each bank has a storage capacity sufficient to store one frame. The frame memory 13 is configured, for example, by a Synchronous Dynamic Random Access Memory (SDRAM).

[0025] The image processing unit 14 performs image processing such as resolution conversion or resizing, distortion correction, shape correction, digital zooming, and adjustment of image color and brightness on the image data expanded in the frame memory 13. The image processing unit 14 executes processing specified by the first control unit 10, and, if necessary, performs processing using parameters input from the first control unit 10. The image processing unit 14 can also execute a combination of multiple image processing operations described above. The image processing unit 14 reads out the processed image data from the frame memory 13 and outputs it to the light modulation device driving circuit 172 .

[0026] The operation unit 15 includes an operation panel 151 and a remote control light receiving unit 152 .

[0027] The operation panel 151 is provided, for example, on the housing of the projector 1, and includes various switches such as a power switch for turning on and off the power of the projector 1. When a switch is operated, the operation panel 151 outputs a signal corresponding to the operated switch to the first control unit 10. The remote control light receiving unit 152 includes a light receiving sensor that receives an infrared signal transmitted by the remote control 3, a circuit that decodes the infrared signal received by the light receiving sensor, etc. The remote control light receiving unit 152 outputs a signal corresponding to the infrared signal received by the light receiving sensor to the first control unit 10. The signal that the remote control light receiving unit 152 outputs to the first control unit 10 is a signal corresponding to the switch of the remote control 3 that has been operated.

[0028] The projector 1 includes a projection unit 16 and a drive unit 17 that drives the projection unit 16. The projection unit 16 includes a light source 161, a light modulation device 162, and a projection optical system 163. The drive unit 17 includes a light source drive circuit 171, a light modulation device drive circuit 172, and a projection optical system drive circuit 173.

[0029] The light source drive circuit 171 is connected to the first control unit 10 via the bus 19, and is also connected to the light source 161. The light source drive circuit 171 turns the light source 161 on or off under the control of the first control unit 10.

[0030] The light modulation device driving circuit 172 is connected to the first control unit 10 via a bus 19, and is also connected to the light modulation device 162. The light modulation device driving circuit 172 drives the light modulation device 162 under the control of the first control unit 10, and draws an image on the light modulation element of the light modulation device 162 on a frame-by-frame basis. Image data corresponding to each primary color of RGB is input to the light modulation device driving circuit 172 from the image processing unit 14. R represents red, G represents green, and B represents blue. The light modulation device driving circuit 172 converts the input image data into data signals suitable for operation of the liquid crystal panels, which are the light modulation elements of the light modulation device 162. The light modulation device driving circuit 172 applies a voltage to each pixel of each liquid crystal panel based on the converted data signals, and draws an image on each liquid crystal panel.

[0031] The light source 161 is configured by a lamp such as a halogen lamp, a xenon lamp, or an ultra-high pressure mercury lamp, or a solid-state light source such as an LED or laser light source. The light source 161 is turned on by power supplied from a light source drive circuit 171, and emits light toward the light modulation device 162.

[0032] The light modulation device 162 includes, for example, three liquid crystal panels corresponding to the three primary colors of RGB. Light emitted from the light source 161 is separated into three color lights of RGB, and each is incident on a corresponding liquid crystal panel. Each of the three liquid crystal panels is a transmissive liquid crystal panel, and generates image light by modulating the light that passes through it. The image light that has passed through each liquid crystal panel and been modulated is combined by a combining optical system such as a cross dichroic prism, and is emitted to the projection optical system 163. In this embodiment, the light modulation device 162 is illustrated as having a transmissive liquid crystal panel as the light modulation element, but the light modulation element may be a reflective liquid crystal panel or a digital micromirror device.

[0033] The projection optical system 163 includes a projection lens 164 that forms an image on the screen SC using the image light modulated by the light modulation device 162. The projection lens 164 of this embodiment is a zoom lens that projects the image light modulated by the light modulation device 162 at a desired magnification. The projection optical system 163 includes a zoom mechanism that enlarges or reduces the projection image G projected onto the screen SC, a focus adjustment mechanism that adjusts the focus, and the like.

[0034] A projection optical system drive circuit 173 is connected to the projection optical system 163. The projection optical system drive circuit 173 is connected to the bus 19. Under the control of the first control unit 10, the projection optical system drive circuit 173 moves the projection lens 164 in a plane perpendicular to the optical axis, and performs lens shift adjustment to move the projection image G projected onto the screen SC in the X-axis and Z-axis directions.

[0035] As described above, the first processor 110 functions as the projection control unit 111, the UI processing unit 112, the adjustment information generation unit 113, the transmission unit 114, the reception unit 115, and the acceptance unit .

[0036] The projection control unit 111 controls the image processing unit 14, the drive unit 17, etc. to display the projection image G on the screen SC.

[0037] Specifically, the projection control unit 111 controls the image processing unit 14 to process the image data expanded in the frame memory 13. At this time, the projection control unit 111 reads out parameters necessary for the processing by the image processing unit 14 from the first memory 120 and outputs them to the image processing unit 14.

[0038] The projection control unit 111 controls the light source drive circuit 171 and the light modulation device drive circuit 172 to turn on the light source 161 using the light source drive circuit 171 and to drive the light modulation device 162 using the light modulation device drive circuit 172, thereby causing the projection unit 16 to display the projection image G. The projection control unit 111 also controls the projection optical system 163 to start a motor and adjust the zoom and focus of the projection optical system 163. The projection control unit 111 also reads lens position parameters from the setting data 122 and controls the projection optical system drive circuit 173 based on the read lens position parameters to move the projection lens 164 to the lens position indicated by the lens position parameters. The lens position parameters include a parameter indicating the lens position of the projection lens 164 in the vertical direction and a parameter indicating the lens position of the projection lens 164 in the horizontal direction.

[0039] The UI processing unit 112 generates image data for the first UI 1121. The first UI 1121 is a UI related to adjusting the projection image G. When the UI processing unit 112 generates the image data for the first UI 1121, it loads the generated image data for the first UI 1121 into the frame memory 13. The UI processing unit 112 may superimpose the image data for the first UI 1121 on image data already loaded in the frame memory 13, or may overwrite the image data with the image data for the first UI 1121. The UI processing unit 112 also updates the display content of the first UI 1121.

[0040] FIG. 3 is a diagram showing an example of the first UI 1121 projected onto the screen SC.

[0041] 3 is a first UI 1121 for lens shift adjustment. The first UI 1121 for lens shift adjustment has a first display object OB1 and a second display object OB2 superimposed on the first display object OB1.

[0042] The second display object OB2 is an image indicating the positional relationship between the lens shift possible area and the projected image G. The lens shift possible area is an area in which the projected image G can be moved by lens shift adjustment. The second display object OB2 includes a third display object OB3 and a fourth display object OB4 superimposed on the third display object OB3. The third display object OB3 is an image indicating the lens shift possible area. A scale extending vertically and a scale extending horizontally are set in the lens shift possible area indicated by the third display object OB3. The fourth display object OB4 is an image indicating the size of the projected image G and the position of the projected image G in the lens shift possible area.

[0043] The first display object OB1 is an enlarged image of the fourth display object OB4 superimposed on the third display object OB3. The size of the first display object OB1 projected onto the screen SC matches the size of the projection area onto which the projection image G is projected.

[0044] When the projector 1 starts displaying the first UI 1121, the UI processing unit 112 acquires a lens position parameter and a zoom magnification parameter from the setting data 122. Next, the UI processing unit 112 recognizes the size of the projection image G relative to the lens shiftable area and the position of the projection image G within the lens shiftable area based on these acquired parameters, and generates a second display object OB2 based on the recognition result. After generating the second display object OB2, the UI processing unit 112 generates a first display object OB1 by enlarging a fourth display object OB4 indicated by the generated second display object OB2. After generating the first display object OB1 and the second display object OB2, the UI processing unit 112 generates a first UI 1121 by superimposing the second display object OB2 on the upper left of the first display object OB1. Then, the UI processing unit 112 loads image data of the generated first UI 1121 into the frame memory 13.

[0045] Returning to the description of the functional units of the first processor 110, the adjustment information generation unit 113 generates first adjustment information. The adjustment information generation unit 113 outputs the generated first adjustment information to the transmission unit 114. The first adjustment information is information indicating adjustment of the projection image G by a first operation accepted by the acceptance unit 116. The first operation is an operation on the first UI 1121, and is an operation for adjusting the projection image G. For example, if the adjustment of the projection image G is a lens shift adjustment, the first adjustment information includes information indicating the direction in which the projection image G has moved and information indicating the amount of movement of the projection image G. Furthermore, for example, if the adjustment of the projection image G is a zoom magnification adjustment, the first adjustment information is information indicating the zoom magnification after adjustment.

[0046] The transmitting unit 114 transmits the first adjustment information to the control device 2 via the second interface 12. The address of the control device 2 is stored in the first memory 120 in advance.

[0047] The receiving unit 115 receives the second adjustment information from the control device 2 via the second interface 12. The second adjustment information will be described later.

[0048] The reception unit 116 receives user operations on the projector 1. The reception unit 116 receives operations on various switches provided on the housing of the projector 1 via an operation panel 151. The reception unit 116 also receives operations on various switches provided on the remote control 3 via a remote control light receiving unit 152. The reception unit 116 of this embodiment receives a first operation via the operation panel 151 or the remote control light receiving unit 152.

[0049] Next, the configuration of the control device 2 will be described. The control device 2 includes a second control unit 20, a communication unit 21, an input unit 22, and a display unit .

[0050] The second control unit 20 includes a second processor 210 that executes programs such as a CPU or an MPU, and a second memory 220. The second control unit 20 controls each part of the control device 2 by the second processor 210 reading and executing a control program 221 stored in the second memory 220. The second processor 210 functions as an application execution unit 211 by reading and executing an adjustment application 222 stored in the second memory 220.

[0051] The second memory 220 stores programs executed by the second processor 210 and data processed by the second processor 210. The second memory 220 stores a control program 221, an adjustment application 222, and various other data executed by the second processor 210. The second memory 220 has a non-volatile storage area. The second memory 220 may also have a volatile storage area and constitute a work area for the second processor 210.

[0052] The adjustment application 222 is an application program related to adjustment of the projection image G.

[0053] The communication unit 21 is a communication interface equipped with a communication circuit, a connector, etc., and communicates with the projector 1 connected to the network NW in accordance with a predetermined communication standard. The communication standard of the communication unit 21 may be a wireless communication standard or a wired communication standard.

[0054] The input unit 22 has input devices such as operation switches provided on the control device 2, a panel with a touch input function, a mouse, and a keyboard, detects operations on the input devices by the user, and outputs the detection results to the second control unit 20. Based on the input from the input unit 22, the second control unit 20 executes processing corresponding to the operation on the input device.

[0055] The display unit 23 includes a display, and displays information on the display according to the control of the second control unit 20.

[0056] As described above, the second processor 210 functions as the application execution unit 211. The application execution unit 211 communicates with the projector 1 via the communication unit 21. The application execution unit 211 displays the second UI 2211. The application execution unit 211 also updates the display content of the second UI 2211.

[0057] FIG. 4 is a diagram showing an example of the second UI 2211. 4 is the second UI 2211 for lens shift adjustment. The second UI 2211 for lens shift adjustment has a fifth display object OB5. The fifth display object OB5 is an example of a "display object."

[0058] The fifth display object OB5 is an image indicating the positional relationship between the lens shift possible area and the projected image G. The fifth display object OB5 includes a sixth display object OB6 and a seventh display object OB7 superimposed on the sixth display object OB6. The sixth display object OB6 is an image indicating the lens shift possible area. A scale may be set to the lens shift possible area indicated by the sixth display object OB6, as with the third display object OB3. The seventh display object OB7 is an image indicating the size of the projected image G and the position of the projected image G within the lens shift possible area.

[0059] When starting to display the second UI 2211, the application execution unit 211 acquires a lens position parameter and a zoom magnification parameter from the projector 1. Next, based on these acquired parameters, the application execution unit 211 recognizes the size of the projection image G and the position of the projection image G within the lens shift possible area, and generates a fifth display object OB5 based on the recognition result.

[0060] The second UI 2211 has buttons B1, B2, B3, and B4. The buttons B1, B2, B3, and B4 are software buttons. The button B1 is a button that moves the projected image G upward. The button B2 is a button that moves the projected image G to the right. The button B3 is a button that moves the projected image G downward. The button B4 is a button that moves the projected image G to the left.

[0061] The application execution unit 211 generates second adjustment information and transmits the generated second adjustment information to the projector 1. The second adjustment information is information indicating adjustment of the projection image G by a second operation accepted by the application execution unit 211. The second operation is an operation on the second UI 2211, and is an operation for adjusting the projection image G. The application execution unit 211 accepts the second operation via at least one of buttons B1, B2, B3, and B4. For example, if the adjustment of the projection image G is a lens shift adjustment, the second adjustment information includes information indicating a direction in which the projection image G is to be moved and information indicating an amount by which the projection image G is to be moved. Furthermore, for example, if the adjustment of the projection image G is a zoom magnification adjustment, the second adjustment information is information indicating a zoom magnification to be adjusted.

[0062] Next, the operation of the display system 1000 will be described. 5 is a flowchart showing the operation of the display system 1000. In FIG. In the operation shown in FIG. 5, lens shift adjustment is exemplified as the adjustment of the projected image G.

[0063] As shown in the flowchart FA, the application execution unit 211 determines whether or not an instruction to start lens shift adjustment has been received from the user (step SA1).

[0064] When the application executing unit 211 determines that an instruction to start the lens shift adjustment has not been received from the user (step SA1: NO), it performs the determination in step SA1 again.

[0065] On the other hand, if the application execution unit 211 determines that an instruction to start lens shift adjustment has been received from the user (step SA1: YES), it transmits adjustment start information indicating that an instruction to start lens shift adjustment has been received to the projector 1 to be adjusted (step SA2).

[0066] As shown in the flowchart FB, the receiving unit 115 receives the adjustment start information (step SB1).

[0067] Next, the transmitter 114 acquires the lens position parameter and the zoom magnification parameter from the setting data 122 (step SB2).

[0068] Next, the transmitting unit 114 transmits the two types of parameters acquired in step SB2 to the control device 2 (step SB3).

[0069] Next, the UI processing unit 112 generates the first UI 1121 (step SB4).

[0070] Next, the projection control unit 111 displays the first UI 1121 generated in step SB4 on the screen SC (step SB5).

[0071] As shown in the flowchart FB, the application execution unit 211 receives two types of parameters from the projector 1 (step SA3).

[0072] Next, the application execution unit 211 generates the second UI 2211 (step SA4).

[0073] Next, the application executing unit 211 displays the second UI 2211 generated in step SA4 on the screen SC (step SA5).

[0074] Next, the operation of the display system 1000 when the projection image G is adjusted by the first UI 1121 will be described.

[0075] FIG. 6 is a flowchart showing the operation of the display system 1000. 6, a flowchart FC shows the operation of the control device 2, and a flowchart FD shows the operation of the projector 1. In the operation shown in Fig. 6, the projector 1 displays the first UI 1121, and the control device 2 displays the second UI 2211. In the operation shown in FIG. 6, lens shift adjustment is exemplified as an adjustment of the projected image G.

[0076] As shown in the flowchart FD, the accepting unit 116 determines whether or not a first operation has been accepted (step SD1). In the operation shown in Fig. 6, the first operation is an operation on the first UI 1121 for lens shift adjustment, and is an operation to move the projection image G.

[0077] If the receiving unit 116 determines that the first operation has not been received (step SD1: NO), the receiving unit 116 performs the determination in step SD1 again.

[0078] If the receiving unit 116 determines that the first operation has been received (step SD1: YES), the projection control unit 111 controls the projection optical system driving circuit 173 to adjust the position of the projection image G in accordance with the received first operation (step SD2).

[0079] Next, the UI processor 112 updates the first UI 1121 displayed by the projector 1 to the first UI 1121 that corresponds to the adjustment made in step SD2 (step SD3).

[0080] FIG. 7 is a diagram showing an example of the first UI 1121 projected onto the screen SC. 7 illustrates a case where the first operation is an operation to move the projected image G to the right by a first distance. In the case of FIG. 7, the UI processing unit 112 updates the displayed second display object OB2 to the next second display object OB2. That is, within the lens shift possible area indicated by the third display object OB3, the UI processing unit 112 updates the fourth display object OB4 to the second display object OB2 by moving it to the right by a distance corresponding to the first distance. Also, in the case of FIG. 7, the UI processing unit 112 updates the displayed first display object OB1 to the first display object OB1 obtained by enlarging the fourth display object OB4 moved to the right.

[0081] Next, the adjustment information generation unit 113 generates first adjustment information (step SD4). In the case of Fig. 7, the adjustment information generation unit 113 generates first adjustment information indicating that the movement direction of the projection image G is rightward and that the movement amount of the projection image G is a first distance.

[0082] Next, the transmitter 114 transmits the first adjustment information generated in step SD4 to the control device 2 (step SD5).

[0083] As shown in the flowchart FC, the application execution unit 211 receives the first adjustment information from the projector 1 (step SC1).

[0084] Next, the application execution unit 211 updates the fifth display object OB5 of the second UI 2211 based on the first adjustment information received in step SC1 (step SC2).

[0085] FIG. 8 is a diagram showing an example of the second UI 2211. 8 illustrates an example in which the received first adjustment information indicates that the movement direction of the projection image G is rightward and that the movement amount of the projection image G is a first distance. As illustrated in FIG. 8, in step SC2, the application execution unit 211 updates the displayed fifth display object OB5 to the next fifth display object OB5. That is, the application execution unit 211 updates the fifth display object OB5 by moving the seventh display object OB7 to the right by a distance corresponding to the first distance within the lens shift possible area indicated by the sixth display object OB6.

[0086] Next, the operation of the display system 1000 when the projection image G is adjusted in the second UI 2211 will be described.

[0087] FIG. 9 is a flowchart showing the operation of the display system 1000. 9, a flowchart FE shows the operation of the control device 2, and a flowchart FF shows the operation of the projector 1. In the operation shown in FIG. 9, the projector 1 displays the first UI 1121, and the control device 2 displays the second UI 2211.

[0088] As shown in flowchart FE, the application execution unit 211 determines whether or not a second operation has been received (step SE1). The second operation is an operation on the second UI 2211, and is an operation for adjusting the projection image G. In the operation shown in FIG. 9, the second operation is an operation on the second UI 2211 for adjusting the lens shift.

[0089] If the application executing unit 211 determines that the second operation has not been received (step SE1: NO), it performs the determination of step SE1 again.

[0090] If it is determined that the second operation has been received (step SE1: YES), the application execution unit 211 updates the fifth display object OB5 of the second UI 2211 (step SE2).

[0091] Step SE2 will be described with reference to FIG. When the second operation is an operation to move the projection image G to the right by the second distance, the application execution unit 211 updates the fifth display object OB5 as shown in Fig. 8. That is, the application execution unit 211 updates the displayed fifth display object OB5 to a fifth display object OB5 obtained by moving the seventh display object OB7 to the right by the distance corresponding to the second distance within the lens shift-enabled area indicated by the sixth display object OB6.

[0092] Next, the application executing unit 211 generates second adjustment information (step SE3). For example, if the received second operation is an operation to move the projection image G rightward by a second distance, the application executing unit 211 generates second adjustment information indicating that the movement direction of the projection image G is rightward and that the movement amount of the projection image G is the second distance.

[0093] Next, the application execution unit 211 transmits the second adjustment information generated in step SE3 to the projector 1 (step SE4).

[0094] As shown in the flowchart FF, the receiving unit 115 receives the second adjustment information from the control device 2 (step SF1).

[0095] Next, the UI processing unit 112 updates the first UI 1121 based on the second adjustment information received in step SF1 (step SF2).

[0096] Step SF2 will be described with reference to FIG. 7, the UI processing unit 112 updates the first UI 1121. That is, the UI processing unit 112 updates the fourth display object OB4 to the second display object OB2 obtained by moving the fourth display object OB4 to the right by the distance corresponding to the second distance within the lens-shiftable area indicated by the third display object OB3. Furthermore, the UI processing unit 112 updates the first display object OB1 to the first display object OB1 obtained by enlarging the fourth display object OB4 to the right by the distance corresponding to the second distance into the projection area.

[0097] 5, 6, 7, 8, and 9, the adjustment of the projected image G is illustrated as a lens shift adjustment. However, the adjustment of the projected image G is not limited to the lens shift adjustment, and may be a zoom adjustment, a geometric correction adjustment, or the like. For an adjustment other than the lens shift adjustment, the first UI 1121 and the second UI 2211 corresponding to the adjustment other than the lens shift adjustment are displayed.

[0098] FIG. 10 is a diagram showing an example of the first UI 1121 related to zoom adjustment. Comparing Figures 3 and 10 makes it clear NaAs shown, in the first UI 1121 related to zoom adjustment, the second display object OB2 further includes an eighth display object OB8. The eighth display object OB8 is an image indicating the size of the projected image G when the zoom magnification is minimum. The center of the eighth display object OB8 coincides with the center of the fourth display object OB4. Therefore, for example, when the fourth display object OB4 moves due to lens shift adjustment, the eighth display object OB8 moves so that its center coincides with the center of the fourth display object OB4.

[0099] FIG. 11 is a diagram showing an example of the second UI 2211 related to zoom adjustment. Comparing Figures 4 and 11 makes it clear Na As shown, in the second UI 2211 related to zoom adjustment, the fifth display object OB5 further includes a ninth display object OB9. The ninth display object OB9 is an image indicating the size of the projected image G when the zoom magnification is at its minimum. The center of the ninth display object OB9 coincides with the center of the seventh display object OB7. Therefore, for example, 7 Display Object OB 7 is moved by the lens shift adjustment, the ninth display object OB9 moves so that its center coincides with the center of the seventh display object OB7.

[0100] As described above, the control method of the display system 1000 includes the projector 1 displaying a first UI 1121 related to adjustment of the projection image G, the control device 2 communicating with the projector 1 displaying a second UI 2211 which is a UI related to adjustment of the projection image G and includes a fifth display object OB5 corresponding to the projection image G, the projector 1, when receiving a first operation on the first UI 1121, transmitting first adjustment information based on the first operation to the control device 2, the projector 1 adjusting the projection image G based on the first adjustment information, and the control device 2 updating the fifth display object OB5 based on the first adjustment information, the control device 2, when receiving a second operation on the second UI 2211, transmitting second adjustment information based on the second operation to the projector 1, the projector 1 adjusting the projection image G based on the second adjustment information, and the projector 1 updating the first UI 1121 based on the second adjustment information.

[0101] According to this, the projector 1 and the control device 2 display UIs related to the adjustment of the projection image G, the fifth display object OB5 is updated in conjunction with the first operation, and the projection image G is adjusted and the first UI 1121 is updated in conjunction with the second operation. Therefore, it becomes possible to adjust the projection image G simply by looking at either the projection image G of the projector 1 or the display screen of the control device 2. This reduces the number of times that the projection image G of the projector 1 and the display screen of the control device 2 are compared in adjusting the projection image G, thereby reducing the burden on the user in adjusting the projection image G. Furthermore, since the burden on the user in adjusting the projection image G can be reduced, the efficiency of the adjustment work for the projection image G can be improved and the time required to adjust the projection image G can be shortened.

[0102] When the control device 2 receives an instruction to start adjusting the projection image G, the projector 1 displays the first UI 1121, and when the control device 2 receives an instruction to start adjusting the projection image G, the projector 1 displays the second UI 2211.

[0103] According to this, the adjustment of the projected image G can be started with the projector 1 as the starting point.

[0104] When the projector 1 receives an instruction to start adjusting the projection image G, the control device 2 displays the second UI 2211, and when the projector 1 receives an instruction to start adjusting the projection image G, the control device 2 displays the first UI 1121.

[0105] This allows the control device 2 to start adjusting the projection image G.

[0106] The control method of the display control system 1000 includes, when the projector 1 receives a first operation, updating the first UI 1121 based on the first operation, and, when the control device 2 receives a second operation, updating the fifth display object OB5 based on the second operation.

[0107] According to this, the first UI 1121 is updated in conjunction with the first operation, and the fifth display object OB5 of the second UI 2211 is updated in conjunction with the second operation. P This reduces the number of times the user has to compare the projected image G of the projector 1 with the display screen of the control device 2, thereby reducing the burden on the user in adjusting the projected image G.

[0108] The adjustment of the projected image G is a lens shift adjustment, and the first UI 1121 shows the positional relationship between the lens shiftable area in which the projected image G can be moved by the lens shift adjustment and the projected image G, and the fifth display object OB5 shows the positional relationship between the lens shiftable area and the projected image G.

[0109] This reduces the burden on the user in adjusting the lens shift.

[0110] The display system 1000 includes a projector 1 and a control device 2 that communicates with the projector 1. The projector 1 executes the following: displaying a first UI 1121 related to adjustment of a projection image G. The control device 2 executes the following: displaying a second UI 2211 that is a UI related to adjustment of a projection image G and that includes a fifth display object OB5 corresponding to the projection image G. When the projector 1 receives a first operation on the first UI 1121, the projector 1 executes the following: transmitting first adjustment information based on the first operation to the control device 2. The projector 1 adjusts the projection image G based on the first adjustment information. 、 The control device 2 updates the fifth display object OB5 based on the first adjustment information. When the control device 2 receives a second operation on the second UI 2211, the control device 2 transmits second adjustment information based on the second operation to the projector 1. The projector 1 adjusts the projection image G based on the second adjustment information. 、 The projector 1 updates the first UI 1121 based on the second adjustment information.

[0111] According to this, the display system 1000 described above Control method It has the same effect as the effect.

[0112] The above-described embodiment is a preferred embodiment of the present invention, but the present invention is not limited to this embodiment and can be embodied in various modified forms without departing from the spirit of the present invention.

[0113] In the above-described embodiment, an example was given of a case where multiple projectors 1 perform a tiling display, but the display mode performed by multiple projectors 1 is not limited to a tiling display, and for example, a stacking display may be performed in which multiple projected images G are overlaid to display a projected image G with high brightness.

[0114] Furthermore, the functions of the first processor 110 and the second processor 210 may be realized by multiple processors or semiconductor chips.

[0115] Furthermore, each functional unit shown in FIG. 2 indicates a functional configuration and does not limit the specific implementation form. For example, in the projector 1 and the control device 2, it is not necessarily necessary to implement hardware corresponding to each functional unit individually, and it is of course possible to configure the projector 1 and the control device 2 so that a single processor executes a program to realize the functions of multiple functional units.
