[0007] The display device of this embodiment is applied to a direct-view display or a projection display. The display device of this embodiment will be described below with reference to drawings of a projector 1, which is a projection-type display. Note that in each drawing, the size of each component may be shown at a different scale to make each component easier to see.

[0008] 1.Projector configuration FIG. 1 is a diagram showing the configuration of a projector 1. As shown in FIG. The projector 1 projects image light onto a projection target 3 such as a screen, and displays an image on the projection target 3. In this embodiment, a display area 4 is an area on the projection target 3 where an image is displayed by the image light.

[0009] The remote control 2 is used to remotely control the projector 1. In this embodiment, the remote control 2 is a controller capable of at least numeric input operations and gesture operations. Note that the remote control 2 does not have to be a dedicated controller. For example, the remote control 2 may be an information terminal, which will be described later.

[0010] The projector 1 performs function settings for the projector 1 based on a numeric input operation and a gesture operation. The function settings for the projector 1 include, for example, settings related to audio such as volume adjustment, settings related to image adjustment such as brightness adjustment and contrast adjustment, and settings related to installation such as keystone correction adjustment and edge blending adjustment.

[0011] The projector 1 of this embodiment sets the functions of the projector 1 based on numerical input operations and gesture operations using the remote control 2, making it possible to set the functions of the projector 1 more efficiently than setting the functions of the projector 1 by operating only the directional keys 22 of the remote control 2.

[0012] Projector 1 includes a control unit 10, a communication unit 13, a remote control receiving unit 14, an operation panel 15, an image processing unit 16, and a projection unit 17, as well as a bus 19 to which these units are connected. Each unit of projector 1 is configured as follows to set the functions of projector 1 based on numerical input operations and gesture operations using remote control 2.

[0013] The control unit 10 includes a processor 110 and a storage unit 120. The control unit 10 controls each unit of the projector 1 by causing the processor 110 to execute a control program 121 stored in the storage unit 120.

[0014] The processor 110 includes one or more processors such as a CPU (Central Processing Unit). Note that a part or all of the processor 110 may be realized by hardware such as an MPU (Micro-Processing Unit), an SOC (System on a Chip), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array).

[0015] The storage unit 120 is configured from a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 120 stores a control program 121 for controlling the operation of the projector 1, setting data 122, and OSD (On Screen Display) data 123.

[0016] The control program 121 includes a program for setting the functions of the projector 1 based on a numerical value input operation and a gesture operation using the remote control 2. The setting data 122 is a setting value that is set regarding the functions of the projector 1. The setting data 122 is, for example, a value that indicates the volume.

[0017] The OSD data 123 includes information such as a menu screen 5 and a setting screen 6 for setting the functions of the projector 1. The menu screen 5 and the setting screen 6 are, for example, screens shown in Figs. 5 and 7, which will be described later, and are displayed superimposed on the display area 4 that displays an image.

[0018] The projection target 3 may be a flat surface or a surface with projections and recesses. Specifically, it may be, for example, a curtain-shaped screen, the wall of a building, or the surface of a natural object.

[0019] The projection unit 17 includes a light source, a light modulation device, and a projection optical system. The light source is turned on under the control of the control unit 10 and emits light toward the light modulation device. The light source is, for example, 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 modulation device modulates the light emitted from the light source, and is, for example, a transmissive liquid crystal panel, a reflective liquid crystal panel, or a digital micromirror device. The projection optical system provided in the projection unit 17 includes lenses, mirrors, prisms, and the like that form an image of the image light modulated by the light modulation device onto the projection target 3.

[0020] The communication unit 13 is connected to a communication network (not shown), and performs communication with an external video supply device via the communication network to request transmission of a video signal, receive a video signal, and so on.

[0021] The remote control receiving unit 14 receives a radio signal transmitted by the remote control 2 . The wireless signals transmitted by the remote controller 2 include operation signals corresponding to the user's 7 numerical input operation, gesture operation, and numerical input operation.

[0022] The remote control receiver 14 outputs the received operation signal to the control unit 10. The wireless signal transmitted and received between the remote control 2 and the remote control receiver 14 may be, for example, an infrared signal, but may be any other signal.

[0023] The operation panel 15 is provided on the housing of the projector 1 and includes various switches that can be operated by the user 7. The operation panel 15 outputs an operation signal to the control unit 10 in response to the operation of a switch.

[0024] The reception unit 111 receives an input operation from the user 7 based on an operation signal input from the remote control reception unit 14 or the operation panel 15.

[0025] The image processing unit 16 performs various image processing on the video signal input from the video supply device under the control of the control unit 10, and generates an image to be displayed in the display area 4 shown in Fig. 5 etc. The image processing performed by the image processing unit 16 includes, for example, resolution conversion processing, resizing processing, geometric correction processing, digital zoom processing, brightness adjustment processing, projection position correction processing, etc.

[0026] When the user 7 sets the functions of the projector 1 through input operations, the image processing unit 16 generates the setting screen 6 shown in Figure 7, etc. based on the OSD data 123, and combines the setting screen 6 with the image displayed in the display area 4.

[0027] When an operation to change the settings of a function of the projector 1 is performed by an input operation of the user 7, the setting change value generation unit 112 generates a value to be used for changing the setting, hereinafter referred to as the setting change value, in accordance with the operation. For example, when the volume level is to be increased by 5 levels from 10 to 15, the setting change value is the change amount of 5 levels. Note that the setting change value may also be, for example, the value after the change, such as 15 levels in the above example.

[0028] The update unit 113 updates the settings related to the functions of the projector 1 based on the setting change value generated by the setting change value generation unit 112. For example, when an operation is performed to change the volume of the projector 1 from level 10 to level 15, the update unit 113 rewrites the setting data 122 related to the volume.

[0029] In addition to the communication unit 13, the projector 1 may have an interface connected to a video supply device. For example, the projector 1 has an interface that includes communication hardware such as a connector and an interface circuit that conforms to a predetermined communication standard. This interface is, for example, a digital interface such as HDMI (High-Definition Multimedia Interface), Displayport, HDBaseT, or USB (Universal Serial Bus). HDMI, Displayport, and HDBaseT are all registered trademarks.

[0030] 2. Remote control configuration As shown in FIG. 1, the remote control 2 includes a menu key 21 , direction keys 22 , an enter key 23 , numeric keys 24 , a power key 25 , and an acceleration sensor 27 .

[0031] The acceleration sensor 27 is used to detect gesture operations by the user 7. For example, when the user 7 performs an upward gesture operation, the user 7 holds the remote control 2 in a predetermined position, for example, in an upright position, and moves the remote control 2 upward. The movement of the remote control 2 is detected by the acceleration sensor 27, and based on the detection by the acceleration sensor 27, the remote control 2 generates an operation signal corresponding to the upward gesture operation and transmits it to the projector 1. Therefore, the projector 1 can detect that the user 7 has performed an upward gesture operation.

[0032] Similarly, the remote control 2 detects an operation by the user 7 of moving the remote control 2 downward, rightward, leftward, forward, or backward, and generates an operation signal corresponding to the gesture operation in that direction and transmits it to the projector 1. Therefore, the projector 1 can detect that the user 7 has performed a gesture operation downward, rightward, leftward, forward, or backward.

[0033] The menu key 21, direction keys 22, enter key 23, numeric keys 24, and power key 25 are switches arranged on the surface of the housing of the remote control 2. These keys may also be keys displayed on a touch input screen (not shown) of the remote control 2.

[0034] The menu key 21 is used, for example, to display a setting menu for the functions of the projector 1. The direction keys 22 are used, for example, to select a function displayed in the setting menu. The enter key 23 is used, for example, to enter a function to be set. The number keys 24 are used, for example, to enter numerical values. The power key 25 is used to turn the power of the projector 1 on or off.

[0035] When the user 7 presses any of the number keys 24 on the remote control 2 to perform a numeric input operation, the remote control 2 generates an operation signal corresponding to the pressed number key and sends it to the projector 1. Similarly, when the user 7 presses the menu key 21, the direction key 22, the enter key 23, or the power key 25, the remote control 2 generates an operation signal corresponding to the pressed key and sends it to the projector 1.

[0036] 2.1. Information terminal configuration As described above, the remote control 2 may be an information terminal. FIG. 17 is a diagram showing a smartphone 200 as an example of an information terminal. The smartphone 200 includes a processor 210, a memory unit 220, an acceleration sensor 270, and a touch panel-equipped screen 280.

[0037] Processor 210 includes one or more processors, such as a CPU. The storage unit 220 is configured with a ROM, a RAM, etc. The storage unit 220 stores a remote operation program for remotely operating the projector 1. The user 7 downloads the remote operation program from the website of the manufacturer of the projector 1 or the like and installs it in the smartphone 200. Note that the remote operation program may be pre-installed in the smartphone 200 of the user 7.

[0038] The remote control program detects a gesture operation by the user 7 using the acceleration sensor 270, generates an operation signal corresponding to the detected gesture operation, and transmits it to the projector 1. Similarly, the remote control program detects a numeric input operation by the user 7 using the touch panel-equipped screen 280, generates an operation signal corresponding to the detected numeric input operation, and transmits it to the projector 1.

[0039] 3. How to control the projector 2 to 16 are diagrams for explaining a method for controlling the projector 1. In this embodiment, as a specific example of a method for controlling the projector 1, an example of setting three functions, namely, volume adjustment, keystone correction adjustment, and edge blending adjustment, will be described.

FIG. 15A is a diagram showing an example of a setting screen 6. FIG. 15B is a diagram showing an example of the display area 4. FIG. 15C is a diagram showing an example of the display area 4.

[0043] FIG. 16 is a diagram for explaining the flow of operations when adjusting the edge blending of the display area 4 of the projector 1, and shows an example of the setting screen 6.

[0044] 3.1.Volume adjustment 2, in step S1, the projector 1 detects whether or not the user 7 has operated the menu key 21. The projector 1 is controlled based on the control program 121 executed by the processor 110, and repeats the operation of step S1 until operation of the menu key 21 is detected.

[0045] As shown in Figures 4A and 4B, when a user 7 presses the menu key 21 on the remote control 2 to set the functions of the projector 1, the remote control 2 generates an operation signal corresponding to the operation and transmits it to the projector 1.

[0046] When the projector 1 receives an operation signal indicating an operation of the menu key 21 from the remote control 2 via the remote control receiver 14, the process proceeds to step S2.

[0047] 5, the projector 1 displays the menu screen 5 in the display area 4 of the projection target 3. The projector 1 is controlled based on the control program 121 executed by the processor 110, generates the menu screen 5 based on the OSD data 123, synthesizes the menu screen 5 with the image displayed in the display area 4, and displays it on the projection target 3.

[0048] Menu screen 5 shown in FIG. 5 displays a setting menu for audio such as volume adjustment, a setting menu for video adjustment such as brightness adjustment and contrast adjustment, and a setting menu for installation such as keystone correction adjustment and edge blending adjustment. The setting menu can be switched by operating the direction keys 22 on the remote control 2. Fig. 5 shows a state in which the setting menu related to audio is displayed in high brightness and the setting menu related to audio is tentatively selected.

[0049] In step S3, the remote control 2 receives an operation to select a function to be set from the setting menu displayed on the menu screen 5. For example, when the user 7 tentatively selects a setting menu related to audio on the menu screen 5 and presses the enter key 23 as shown in FIGS.

[0050] When the projector 1 receives, via the remote control receiver 14, an operation signal indicating operation of the enter key 23 from the remote control 2, the process proceeds to step S4.

[0051] 7, the setting screen 6 corresponding to the setting menu selected by operating the enter key 23 is displayed. The projector 1 is controlled based on the control program 121 executed by the processor 110, and generates a volume setting screen 61 as the setting screen 6 related to the audio selected based on the OSD data 123. The generated setting screen 61 is combined with the image displayed in the display area 4 and displayed on the projection target 3.

[0052] The volume setting screen 61 includes a numeric bar 611 that extends along the length of the display area 4. The numeric bar 611 indicates the currently set volume level, and in FIG. 7, the volume level is 10. As will be described later, the numeric bar 611 is controlled to expand and contract along the length of the display area 4 in response to an operation to change the volume level. In this embodiment, the numeric bar 611 that expands and contracts along the length of the display area 4 is an example of a numeric bar that expands and contracts along a first direction.

[0053] After displaying the setting screen 6, the projector 1 executes step S5. In step S5, an operation related to setting the functions of the projector 1 using the remote control 2 is accepted. Fig. 3 shows a detailed flowchart of step S5.

[0054] 3, in step S51, the operation of the remote control 2 by the user 7 is determined. The projector 1 is controlled based on the control program 121 executed by the processor 110, and determines the operation of the remote control 2 by the user 7 based on the operation signal of the remote control 2 received by the remote control receiver 14.

[0055] If the operation signal of the remote control 2 received by the remote control receiving unit 14 is a numerical input operation by pressing the numeric keys 24 and a gesture operation using the remote control 2, in steps S52 and S53, the accepting unit 111 accepts the numerical input operation and the gesture operation.

[0056] 3.1.1. Adjust the volume level from level 10 to level 15 8A and 8B, the user 7 presses the number key 24 indicating 5 on the remote control 2, and then, holding the remote control 2 upright, moves the remote control 2 in direction d3 or direction d1 to perform a rightward gesture operation or an upward gesture operation as shown in FIGS. 9A and 9B. This operation causes the remote control 2 to generate an operation signal corresponding to the numeric input operation performed by pressing the number key 24 indicating 5 and an operation signal corresponding to the rightward gesture operation or the upward gesture operation, and transmit these signals to the projector 1.

[0057] When the projector 1 receives, via the remote control receiver 14, an operation signal corresponding to a numerical input operation by pressing the number key 24 indicating 5 on the remote control 2 to the rightward gesture operation or the upward gesture operation, the projector 1 receives the numerical input operation and the gesture operation via the reception unit 111 in steps S52 and S53.

[0058] After accepting the numerical value input operation and the gesture operation, the projector 1 executes step S6. In step S6, the setting change value generation unit 112 generates a setting change value used to change the volume setting based on the numeric input operation and gesture operation received by the reception unit 111. In this example, the setting change value is generated based on the numeric input operation using the numeric key 24 indicating 5 and the rightward gesture operation or the upward gesture operation.

[0059] In this example, the setting change value is a value that increases the volume by the amount corresponding to the number 5 on the numeric key 24. For example, the amount corresponding to 5 is a value corresponding to volume level 5. Note that the amount corresponding to 5 on the numeric key 24 is not limited to the value corresponding to level 5. For example, the amount corresponding to 5 on the numeric key 24 may be programmed to be several times the value corresponding to level 5. If it is desired to increase the volume level from level 0 to level 100 in one go, the amount corresponding to 1 on the numeric key 24 can be set to 100 times the value corresponding to level 1, thereby significantly reducing the burden on the user 7.

[0060] After generating the setting change values, the projector 1 executes step S7. In step S7, the setting screen 6 is updated based on the generated setting change values. As shown in FIG. 10, the volume indicated by the numerical bar 611 is changed from level 10 to level 15 based on the setting change value.

[0061] In this way, the projector 1 of this embodiment eliminates the need for the user 7 to continuously press the direction key 22 on the remote control 2 for a period of time according to the magnitude of the change, or repeatedly press the direction key 22 a number of times according to the magnitude of the change. Therefore, the projector 1 of this embodiment reduces the burden on the user 7, and makes the projector 1 easy to use.

[0062] Furthermore, with the projector 1 of this embodiment, if the user 7 wants to increase the volume, he or she can increase the volume by performing a rightward gesture operation, which moves the remote control 2 along the direction d3, which is the same direction as the extension of the numeric bar 611. This allows the user 7 to perform the operation intuitively, improving operability. In this embodiment, the rightward gesture operation is an example of a gesture operation that moves in a first direction.

[0063] Similarly, in the projector 1 of this embodiment, if the user 7 wants to increase the volume, he or she can increase the volume by moving the remote control 2 in the upward direction d1. This allows the user 7 to operate intuitively, improving operability.

[0064] 3.1.2. Adjust the volume level from level 15 to level 5 11A and 11B, the user 7 presses the number key 24 indicating 10 on the remote control 2, and then, holding the remote control 2 upright, moves the remote control 2 in the direction d4 or d2 to perform a leftward gesture operation or a downward gesture operation as shown in FIGS. 12A and 12B. This operation causes the remote control 2 to generate an operation signal corresponding to the numeric input operation performed by pressing the number key 24 indicating 10 and an operation signal corresponding to the leftward gesture operation or the downward gesture operation, and transmit these to the projector 1.

[0065] When the projector 1 receives, via the remote control receiver 14, an operation signal corresponding to a numerical input operation by pressing the numeric key 24 indicating 10 from the remote control 2 and an operation signal corresponding to a downward gesture operation, in steps S52 and S53, the reception unit 111 receives the numeric key operation and the gesture operation.

[0066] After accepting the numerical value input operation and the gesture operation, the projector 1 executes step S6. In step S6, the setting change value generation unit 112 generates a setting change value used to change the volume setting based on the numeric input operation and gesture operation received by the reception unit 111. In this example, the setting change value is generated based on the numeric input operation using the numeric key 24 indicating 10 and the downward gesture operation.

[0067] In this example, the setting change value is a value that decreases the volume by an amount corresponding to 10 on the numeric key 24. For example, the amount corresponding to 10 is a value that corresponds to a volume level of 10.

[0068] After generating the setting change values, the projector 1 executes step S7. In step S7, the setting screen 6 is updated based on the generated setting change values. As shown in FIG. 13, the volume indicated by the numerical bar 611 is changed from level 15 to level 5 based on the setting change value.

[0069] After updating the setting screen 6, the projector 1 executes step S8. In step S8, the continuation or termination of the setting change is monitored. If it is to be continued, the process returns to step S5, and if it is to be terminated, the process exits the flowchart.

[0070] In this way, the projector 1 of this embodiment eliminates the need for the user 7 to continuously press the direction key 22 on the remote control 2 for a period of time according to the magnitude of the change, or repeatedly press the direction key 22 a number of times according to the magnitude of the change. Therefore, the projector 1 of this embodiment reduces the burden on the user 7, and makes the projector 1 easy to use.

[0071] Furthermore, with the projector 1 of this embodiment, if the user 7 wants to lower the volume, he or she can do so by performing a leftward gesture operation of moving the remote control 2 along direction d4, which is the same direction as the direction in which the numeric bar 611 shrinks. This allows the user 7 to perform the operation intuitively, improving operability. In this embodiment, the leftward gesture operation is an example of a gesture operation of moving in a first direction.

[0072] Similarly, in the projector 1 of this embodiment, if the user 7 wants to lower the volume, he or she can do so by moving the remote control 2 in the downward direction d2. This allows the user 7 to operate intuitively, improving operability.

[0073] 3.2. Keystone Correction Adjustment When the user 7 selects a setting menu related to keystone correction from the menu screen 5 shown in FIG. 5, the projector 1 executes step S4 to display a keystone correction setting screen 62 as the setting screen 6 in the display area 4, as shown in FIG. 15A. The keystone correction setting screen 62 includes a numerical bar 621 indicating the adjustment value for vertical keystone correction and a numerical bar 622 indicating the adjustment value for horizontal keystone correction. In this embodiment, the setting screen 62 is an example of a first setting screen.

[0074] 14A and 14B, when the user 7 performs an upward gesture operation of moving the remote control 2 in direction d1, the shape of the display area 4 shown in Fig. 15B changes from the vertical trapezoid indicated by display area 43 to the rectangle indicated by display area 41. On the other hand, when the user 7 performs a downward gesture operation of moving the remote control 2 in direction d2, the shape of the display area 4 changes from the vertical trapezoid indicated by display area 42 to the rectangle indicated by display area 41.

[0075] When the user 7 performs a numeric input operation together with an upward gesture operation or a downward gesture operation, the projector 1 generates a setting change value based on the operation signal corresponding to the numeric input operation and the operation signal corresponding to the upward gesture operation or the downward gesture operation, and updates the display of the numeric bar 621 indicating the adjustment value for vertical keystone correction. For example, if the user 7 presses the numeric key 24 indicating 15 on the remote control 2 together with an upward gesture operation, the numeric bar 621 extends from a position indicating 50 to a position indicating 65. The shape of the display area 4 is corrected to a shape indicated by the setting change value, similar to the numeric bar 621.

[0076] In this embodiment, an upward gesture operation or a downward gesture operation that moves the remote control 2 in direction d1 or direction d2 is an example of a gesture operation that moves in the direction of the short side of the display area 4, and a setting change value generated based on an upward gesture operation or a downward gesture operation is an example of a second setting change value.

[0077] The setting change value generated by setting change value generation unit 112 may be configured to be three times larger than the value indicated by number key 24. In this case, when user 7 performs an upward gesture operation and presses number key 24 indicating 15 on remote control 2, number bar 621 will extend from 50 to a position indicating 95. This makes it possible to further reduce the burden on user 7 and realize a projector 1 that is easy to use.

[0078] 14A and 14B, when the user 7 performs a rightward gesture operation of moving the remote control 2 in direction d3, the shape of the display area 4 changes from the horizontal trapezoid indicated by display area 44 to the rectangle indicated by display area 41, as shown in Fig. 15C. On the other hand, when the user 7 performs a leftward gesture operation of moving the remote control 2 in direction d4, the shape of the display area 4 changes from the horizontal trapezoid indicated by display area 45 to the rectangle indicated by display area 41.

[0079] When the user 7 performs a rightward or leftward gesture operation and a numeric input operation, the projector 1 generates a setting change value based on the operation signal corresponding to the numeric input operation and the operation signal corresponding to the rightward or leftward gesture operation, and updates the value of the numeric bar 622 indicating the adjustment value for horizontal keystone correction. For example, if the user 7 presses the numeric key 24 indicating 10 on the remote control 2 together with a leftward gesture operation, the numeric bar 622 shrinks from 50 to a position indicating 40. The shape of the display area 4 is corrected to the shape indicated by the setting change value, similar to the numeric bar 622.

[0080] In this embodiment, a rightward gesture operation or a leftward gesture operation that moves the remote control 2 in direction d3 or direction d4 is an example of a gesture operation that moves in the long side direction of the display area 4, and a setting change value generated based on a rightward gesture operation or a leftward gesture operation is an example of a first setting change value.

[0081] 3.3.Edge Blending Adjustment When the user 7 selects the setting menu for edge blending from the menu screen 5 shown in FIG. 5, the main projector 1a among the projectors 1a, 1b, 1c, and 1d displays the edge blending setting screen 63 as shown in FIG.

[0082] Edge blending setting screen 63 includes boundary lines Y1, Y2, X1, and X2. Boundaries Y1, Y2, X1, and X2 indicate the boundaries of areas where multiple display areas among four display areas 4a, 4b, 4c, and 4d overlap in display area 4, which is formed by four display areas 4a, 4b, 4c, and 4d by four projectors 1a, 1b, 1c, and 1d.

[0083] When the user 7 performs an upward gesture operation of moving the remote control 2 in direction d1, the boundary line Y1 moves in direction d1, and when the user 7 performs a downward gesture operation of moving the remote control 2 in direction d2, the boundary line Y1 moves in direction d2.

[0084] When the user 7 performs a numerical input operation together with an upward gesture operation or a downward gesture operation, the projector 1 generates a setting change value based on an operation signal corresponding to the numerical input operation and an operation signal corresponding to the upward gesture operation or the downward gesture operation, and updates the display position of the boundary line Y1.

[0085] When the user 7 performs a rightward gesture operation of moving the remote control 2 in direction d3, the boundary line X1 moves in direction d3, and when the user 7 performs a leftward gesture operation of moving the remote control 2 in direction d4, the boundary line X1 moves in direction d4.

[0086] When the user 7 performs a rightward or leftward gesture operation along with a numerical input operation, the projector 1 generates a setting change value based on an operation signal corresponding to the numerical input operation and an operation signal corresponding to the rightward or leftward gesture operation, and updates the display position of the boundary line X1.

[0087] 3.4. Adjustment using gestures only or directional keys only In the above example, the functions of the projector 1 are set by numerical input operations using the numeric keys 24 and gesture operations, but the projector 1 of this embodiment is configured so that the functions of the projector 1 can be set by gesture operations alone or by operating the directional keys 22 alone.

[0088] 3, if the receiving unit 111 receives only a gesture operation, the setting change value generating unit 112 generates a setting change value based only on the gesture operation. For example, if the function setting is to adjust the volume and the gesture operation is an upward gesture operation, the generated setting change value is a value that increases the volume by level 1.

[0089] 3, if the reception unit 111 receives only the operation of the directional key 22, the setting change value generation unit 112 generates a setting change value based only on the operation of the directional key 22. For example, if the function setting is to adjust the volume and the directional key 22 is the down or left key, the generated setting change value is a value that decreases the volume by level 1.

[0090] In step S7, the projector 1 updates the setting screen 6 based on the generated setting change value. For example, the volume indicated by the numerical bar 611 is changed from level 10 to level 11, or from level 10 to level 9.

[0091] In the above-described embodiment, an example has been described in which the display device of this embodiment is applied to the projector 1, but the display device of this embodiment can also be applied to a direct-view display. In a direct-view display, the display area 4 viewed by the user 7 is provided on the screen of a light modulation device (not shown).

[0092] As described above, the control method of the projector 1 as a control method of the display device of this embodiment includes the projector 1 displaying the setting screen 6 for setting the functions of the projector 1, the projector 1 accepting a numerical input operation input via the remote control 2, the projector 1 accepting a gesture operation input via the remote control 2, the projector 1 generating a setting change value based on the numerical input operation and the gesture operation, and the projector 1 updating the setting screen 6 based on the setting change value.

[0093] This reduces the burden on the user 7 and makes it possible to realize a user-friendly projector 1. More specifically, the projector 1 of this embodiment sets the functions of the projector 1 based on a numeric input operation and a gesture operation using the remote control 2, thereby making it possible to set the functions of the projector 1 more efficiently than by operating only the direction keys 22 of the remote control 2.

[0094] In the control method for the display device of this embodiment, when the setting screen 6 includes a numeric bar 611 that expands and contracts along the longitudinal direction of the display area 4 as a first direction, and the gesture operation includes a rightward gesture operation or a leftward gesture operation that moves along the longitudinal direction of the display area 4, updating the setting screen 6 by the projector 1 includes the projector 1 expanding or contracting the numeric bar 611 along the longitudinal direction of the display area 4 based on the setting change value.

[0095] This reduces the burden on the user 7 and makes it possible to realize a user-friendly projector 1. Furthermore, because the direction of the gesture operation and the direction in which the numeric bar 611 expands and contracts are the same, the user 7 can intuitively operate the projector 1. This further improves the operability of the projector 1.

[0096] In the control method for the display device of this embodiment, the projector 1 displays, as the setting screen 6, a setting screen 62 as a first setting screen that corrects the shape of the display area 4 on which the setting screen 6 is displayed; if the gesture operation includes a rightward gesture operation or a leftward gesture operation as a gesture operation for moving in the long-side direction of the display area 4, generating a first setting change value that corrects the shape of the long-side direction of the display area 4; if the gesture operation includes an upward gesture operation or a downward gesture operation as a gesture operation for moving in the short-side direction of the display area 4, generating a second setting change value that corrects the shape of the short-side direction of the display area 4; and updating the setting screen 62 based on the first setting change value and / or the second setting change value.

[0097] This reduces the burden on the user 7 and makes it possible to realize a user-friendly projector 1. Furthermore, in the keystone correction that corrects the shape of the display area 4, the direction of the gesture operation matches the direction in which the display area 4 is corrected, so the user 7 can intuitively operate the projector 1. This further improves the operability of the projector 1.

[0098] In the control method for a display device of this embodiment, the remote control 2 is an information terminal. This allows an information terminal such as a smartphone 200 to be used as the remote control 2, thereby increasing the versatility of the projector 1. Furthermore, since there is no need to prepare a dedicated remote control, costs can be reduced and industrial utility can be increased.

[0099] Although the present invention has been described above based on preferred embodiments, the present invention is not limited to the above-described embodiments. Furthermore, the configuration of each part of the present invention can be replaced with any configuration that exhibits the same function as the above-described embodiments, and any configuration can be added.
