The projection unit 17 may include a zoom mechanism, a focus adjustment mechanism for adjusting focus, and the like.

The projector 1 includes a communication section 13, a remote control light receiving section 14, an operation panel 15, and an image processing section 16. Each of these units is connected to the control unit 10 via a bus 19.

The communication unit 13 is connected to a video supply device that supplies video signals to the projector 1. The communication unit 13 is, for example, a communication device that communicates with the video supply device via a communication network (not shown). In this case, the communication unit 13 includes, for example, a connector for connecting an Ethernet cable and a communication circuit for transmitting and receiving signals. The communication unit 13 may be a wireless communication device that performs wireless communication such as Wi-Fi. Ethernet is a registered trademark. Wi-Fi is a registered trademark.

The remote control light receiving unit 14 receives a wireless signal transmitted by the remote control 2. The remote control light receiving section 14 generates an operation signal by decoding the received signal and outputs it to the control section 10. The wireless signals transmitted and received between the remote control 2 and the remote control light receiving section 14 include, for example, infrared signals, but may be other signals.

The remote control 2 has an operation section 20 that is operated by a user. The operation unit 20 includes, for example, a MENU key 21, a direction key 22, and an enter key 23. These are switches placed on the surface of the housing of the remote controller 2. When one of the MENU key 21, direction key 22, and enter key 23 is operated, the remote control 2 generates an operation signal corresponding to the operated switch and wirelessly transmits it to the projector 1. The remote control light receiving unit 14 generates an operation signal indicating a switch operated on the remote control 2 by receiving and decoding a wireless signal transmitted from the remote control 2. The remote control light receiving section 14 outputs an operation signal to the control section 10.

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

The image processing section 16 performs image processing on the video signal input from the video supply device under the control of the control section 10 . Examples of the image processing performed by the image processing unit 16 include resolution conversion processing, resizing processing, geometric correction processing, digital zoom processing, brightness adjustment processing, and projection position correction processing. The image processing unit 16 also performs a process of generating an OSD image to be superimposed on a video, and a process of compositing an OSD image with a video. The image processing unit 16 generates a display signal for displaying the image after image processing, and outputs it to the light modulation device of the projection unit 17.

The image processing section 16 may be configured by, for example, an integrated circuit. This type of integrated circuit includes LSI, ASIC (Application Specific Integrated Circuit), PLD (Programmable Logic Device), FPGA (Field-Programmable Gate Array), Including SoC (System-on-a-chip). Further, an analog circuit may be included as part of the integrated circuit configuration, and the integrated circuit and the control unit 10 may be integrated.

In addition to the communication section 13, the projector 1 may have an interface connected to a video supply device. For example, the projector 1 includes an interface that includes communication hardware such as a connector and an interface circuit that comply with 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 and Displayport are registered trademarks. HDBaseT is a registered trademark. Furthermore, the projector 1 may be configured to include analog video terminals such as an RCA terminal, a VGA terminal, an S terminal, and a D terminal as an interface, and to be capable of receiving analog video signals.

The processor 110 reads and executes the control program 121 stored in the storage unit 120, thereby executing various processes through cooperation of hardware and software. The processor 110 includes a reception section 111, a projection control section 112, and a setting section 113. These are functional units configured by the processor 110 executing the control program 121.

The receiving unit 111 receives a user's input operation based on an operation signal input from the remote control light receiving unit 14 or the operation panel 15.

The projection control unit 112 causes the projection unit 17 to project an image in response to the user's input operation received by the reception unit 111. For example, the projection control unit 112 causes the projection unit 17 to project the video selected by the operation received by the reception unit 111. Furthermore, the projection control section 112 controls the image processing section 16 to execute image processing. For example, the projection control unit 112 causes the image processing unit 16 to generate an OSD image, and causes the projection unit 17 to project the OSD image onto the projection target 3 along with the video. The OSD image is, for example, a setting image for setting functions of the projector 1.
When the receiving unit 111 receives a setting operation using an OSD image, the setting unit 113 performs settings regarding the functions of the projector 1 according to the operation. For example, the setting unit 113 rewrites the setting data 122 regarding the display form of the setting image when a setting operation for setting the display form of the setting image projected by the projector 1 is accepted.

The control program 121 stored in the storage unit 120 is a program executed by the processor 110.

The setting data 122 includes setting contents regarding the functions of the projector 1. The setting data 122 includes, for example, data regarding the display format when displaying the OSD image of the setting image.

FIG. 2 is a schematic diagram showing an example of the setting data 122. The setting data 122 shown in FIG. 2 specifies the display form of the OSD image in association with setting items related to the functions of the projector 1. FIG. 2 shows a main menu, color mode, brightness, tracking, blanking, sharpness, and detail emphasis as examples of setting items. The main menu refers to an OSD image of a menu that is displayed first when, for example, the MENU key 21 of the remote controller 2 is operated. The color mode refers to an OSD image for setting the color tone mode of the image projected by the projection unit 17. Brightness refers to an OSD image for setting the brightness of an image projected by the projection unit 17. Tracking refers to an OSD image for adjusting tracking of an image projected by the projection unit 17. Blanking refers to an OSD image for making settings related to blanking adjustment of the image projected by the projection unit 17. Sharpness refers to an OSD image for adjusting the sharpness of an image projected by the projection unit 17. Detail enhancement refers to an OSD image related to enhancement of the display state of a part of the image projected by the projection unit 17.

Setting items included in the setting data 122 correspond to image adjustment functions of the projector 1. For example, the color mode adjustment function and the brightness adjustment function shown in FIG. 2 correspond to the adjustment function for the entire image that the projection unit 17 projects onto the projection target 3. The functions of tracking adjustment, blanking adjustment, sharpness adjustment, and detail emphasis correspond to adjustment functions for a part of the image that the projection unit 17 projects onto the projection target 3. The image adjustment function that the projector 1 has is not limited to the example shown in FIG. Examples include overscan settings, geometric correction, color matching adjustment, point correction, contrast adjustment, color density adjustment, gamma correction, effect settings, and the like.

For some setting items related to the functions of the projector 1, the display format of the OSD image for setting the settings is specified. The setting data 122 includes information indicating whether the display form of the OSD image is fixed or variable in association with each setting item. In the example of FIG. 2, the display format of the OSD image is fixed with respect to color mode, brightness, tracking, and blanking, and the specifications cannot be changed by user operations.

The OSD data 123 is data of an OSD image generated by the image processing unit 16 or data for the image processing unit 16 to generate the OSD image. The OSD data 123 includes character strings and images included in the OSD image. For example, the OSD data 123 includes data for generating an OSD image regarding a setting menu for setting functions of the projector 1. Further, the OSD data 123 includes data such as the display size of the OSD image.

[2. Image display format]
Here, the display form of the OSD image projected by the projector 1 will be explained.
Note that in the following description, the projector 1 projecting a video or image onto the projection target 3 by the projection unit 17 is referred to as display. The image formed on the projection target 3 by the image light projected by the projection unit 17 is called a display image. The displayed image may be a moving image, that is, a video, or a still image.

FIG. 3 is a diagram illustrating an example of transition of display format by the projector 1.
A display area 300 shown in FIG. 3 is an area where the projector 1 can display a display image on the projection target 3. The display area 300 is, for example, a range in which the projector 1 can project image light, or a range in which the projector 1 can display a display image subjected to geometric correction processing.

The projector 1 of this embodiment can switch between the display format shown in FIG. 3(A), the display format shown in FIG. 3(B), and the display format shown in FIG. 3(C).
FIG. 3A shows a state in which a display image is displayed in the entire display area 300. The first image P1 is a display image displayed by the projector 1. The content of the first image P1 and whether the first image P1 is a video or a still image do not matter.

The projector 1 displays a settings screen when a user's operation instructs to perform settings related to the functions of the projector 1. The display format of FIG. 3(B) and the display format of FIG. 3(C) are display formats when displaying a setting screen. Here, the display form of FIG. 3(B) is assumed to be an L-shaped display, and the display form of FIG. 3(C) is assumed to be a normal OSD display.

When the projector 1 performs the L-shaped display shown in FIG. 3(B), the display area 300 is divided into a first area 301 and a second area 302. The first area 301 and the second area 302 are part of the display area 300 and do not overlap with each other. In the first area 301, a reduced image P2 obtained by reducing the first image P1 is displayed. A setting image 321 is displayed in the second area 302.

FIG. 4 is a diagram showing a display example of the setting image 321 when L-shaped display is performed. In the display example of FIG. 4, an L-shaped second area 302 is provided in the display area 300. The shape of the second region 302 is arbitrary, but preferably has a shape along at least one of the sides of the display region 300 in the rectangular display region 300. Specifically, the second region 302 is a vertically long rectangle or a horizontally long rectangle. In the example of FIG. 4, the second area 302 is L-shaped along two adjacent sides of the display area 300. When the second area 302 is shaped along the sides of the display area 300, the first area 301 can be made into a rectangular area, which has the advantage that the reduced image P2 can be displayed in an easy-to-see manner. The setting image 321 may be an image for selecting a setting item, or may be an image for inputting a setting value regarding a specific setting item. The settings image 321 corresponds to an example of a first settings image.

In the second area 302, a function selection section 325 is displayed. The function selection section 325 is an image for selecting setting items. The function selection section 325 may be considered as a part of the setting image 321, or may be considered as an image independent from the setting image 321. The function selection section 325 displays a list of settable setting items. The user selects the setting item displayed on the function selection section 325 by operating the operation section 20 or the operation panel 15.

At the bottom of the second area 302, a setting image 321 corresponding to the setting item selected in the function selection section 325 is displayed. FIG. 4 illustrates a state in which sharpness adjustment is selected in the function selection section 325. The setting image 321 includes an explanation display section 327 including a character string explaining sharpness adjustment, and an operation image 328 for performing sharpness adjustment. The operation image 328 is, for example, a slide bar for specifying an adjustment value for sharpness adjustment. While no setting item is selected in the function selection section 325, the projector 1 may display blanks at the display positions of the explanation display section 327 and the operation image 328.

When performing L-shaped display, the first area 301 and the second area 302 do not overlap, so the reduced image P2 is not hidden by the setting image displayed in the second area 302. Therefore, the user can perform settings using the setting image displayed in the second area 302 while viewing the entire reduced image P2 displayed in the first area 301. The L-shaped display is suitable, for example, when setting image processing for the entire display image of the projector 1.

When performing the normal OSD display shown in FIG. 3C, the projector 1 provides a third area 303 overlapping the first image P1 displayed in the entire display area 300. In the third area 303, an OSD setting image 322 is displayed. The OSD setting image 322 is a setting image displayed when setting the functions of the projector 1. The OSD setting image 322 may be an image for selecting a setting item, or may be an image for inputting a setting value regarding a specific setting item. The OSD setting image 322 corresponds to an example of a second setting image.

When performing normal OSD display, the first image P1 is not reduced, so settings can be easily made while viewing the first image P1. For example, if the setting target using the OSD setting image 322 is a part of the first image P1 and the setting target is not hidden by the third area 303, the setting can be performed more easily. Therefore, normal OSD display is suitable, for example, when setting image processing for a portion of a displayed image.

When the user makes settings regarding the functions of the projector 1, the projector 1 selects and executes either the L-shaped display or the normal OSD display according to the setting data 122. The functions of the projector 1 include functions related to image processing or image adjustment for the entire display image of the projector 1. These functions can be said to be functions for adjusting the entire first image P1, and are an example of the first function. For example, a color mode adjustment function and a brightness adjustment function correspond to examples of the first function. Further, the functions of the projector 1 include functions related to image processing or image adjustment for a part of the image displayed by the projector 1. These functions can be referred to as functions for adjusting a part of the first image P1, and are an example of the second function. For example, each adjustment function of tracking adjustment, blanking adjustment, sharpness adjustment, and detail emphasis corresponds to an example of the second function.

Among the setting items that can be selected by the user, setting items related to image processing or image adjustment for the entire display image of the projector 1, that is, setting items related to the first function, are suitably displayed in an L shape. Therefore, for setting items related to image processing or image adjustment for the entire display image of the projector 1, L-shaped display is fixedly set by the setting data 122. This kind of setting items are, for example, setting items related to functions of the projector 1 such as color mode adjustment, brightness adjustment, contrast adjustment, color density adjustment, gamma adjustment, and effect setting. These functions correspond to an example of the first function.

Among the setting items that can be selected by the user, setting items related to image processing or image adjustment for a portion of the projector 1, that is, setting items related to the second function, are usually suitable for OSD display. Therefore, for setting items related to image processing or image adjustment for a portion of the display image of the projector 1, the normal OSD display is fixed and set by the setting data 122. Setting items of this type are, for example, setting items related to functions such as tracking adjustment, overscan adjustment, geometric correction, blanking adjustment, edge blending adjustment, and color matching adjustment. These functions correspond to an example of the second function.

Furthermore, there may be setting items that are valid for both the L-shaped display and the normal OSD display. Examples include sharpness adjustment and detail enhancement settings. Regarding these setting items, the user can arbitrarily specify whether the projector 1 performs L-shaped display or normal OSD display. That is, the setting data 122 specifies the display form specified by the user for these setting items.

[3. Projector operation]
FIG. 5 is a flowchart showing an example of the operation of the projector 1.
The operations of steps S11, S12, S16, S23, and S26 are executed by the reception unit 111. The operations of steps S13 to S15, S17 to S22, S25, and S27 to S29 are executed by the projection control section 112. The operation in step S24 is executed by the setting unit 113.

The projector 1 accepts menu operations by the user (step S11). The menu operation is an operation for instructing the display of a setting menu image, and is, for example, an operation of the MENU key 21. Subsequently, the projector 1 receives a display selection operation for selecting the display format of the setting menu image (step S12). The display selection operation is an operation for selecting or specifying either L-shaped display or normal OSD display as the display form of the setting menu image. The display selection operation is performed using, for example, the direction keys 22 and enter key 23 of the remote controller 2, or the operation panel 15.

The projector 1 determines whether the display format selected by the display selection operation is a normal OSD display (step S13). If the normal OSD display is selected (step S13; YES), the projector 1 displays the setting menu image in the display area 300 in the normal OSD display (step S14). For example, the projector 1 displays the third area 303 in FIG. 3(C), and displays a setting menu image in the third area 303. After that, the projector 1 moves to step S16.

If the normal OSD display is not selected in the display selection operation (step S13; NO), the projector 1 determines that the L-shaped display has been selected, and displays the setting menu image in the L-shaped display in the display area 300 ( Step S15). For example, the projector 1 finishes displaying the first image P1, forms the first area 301 and the second area 302 in FIG. A setting menu image is displayed in area 302. After that, the projector 1 moves to step S16.

In step S16, the projector 1 waits for an operation to select a setting item using the setting menu image (step S16). The operation of selecting a setting item can be said to be an operation of selecting a function to be set. For example, an operation of selecting a setting item related to the first function, such as a color mode adjustment function or a brightness adjustment function, corresponds to an example of an operation of selecting the first function. Further, for example, the operation of selecting setting items related to the second function, such as tracking adjustment, blanking adjustment, sharpness adjustment, and detail emphasis, corresponds to an example of the operation of selecting the second function.

If an operation for selecting a setting item is performed (step S16; YES), the projector 1 ends displaying the currently displayed setting image (step S17). The settings image being displayed includes the settings image displayed in steps S19, S21, and S22, which will be described later, and may also include the settings menu image displayed in step S14 or S15.

The projector 1 determines whether the display format corresponding to the setting item selected in step S16 is fixed to the normal OSD display (step S18). The determination in step S18 is performed, for example, by referring to the setting data 122. If it is determined that the display format is fixed to the normal OSD display (step S18; YES), the projector 1 displays the setting image in the normal OSD display (step S19). For example, the projector 1 forms the third area 303 in FIG. 3C over the first image P1, and displays the OSD setting image 322 in the third area 303. After that, the projector 1 moves to step S26.

If it is determined that the display format is not fixed to the normal OSD display (step S18; NO), the projector 1 determines whether the display format corresponding to the setting item selected in step S16 is fixed to the L-shaped display. (Step S20). If it is determined that the display format is fixed to the L-shaped display (step S20; YES), the projector 1 displays the setting image in the L-shaped display (step S21). After that, the projector 1 moves to step S26.

If it is determined that the display format is not fixed to the L-shaped display (step S20; NO), the projector 1 displays the setting image in the same display format as the previous display of the setting image (step S22). The operation in step S22 is realized, for example, by writing the display format into the setting data 122 when displaying the setting image. In this case, the projector 1 may write the display format corresponding to the setting item selected in step S16 into the setting data 122, and refer to the setting data 122 in step S22.

After displaying the setting image in step S22, the projector 1 determines whether a display switching operation has been performed to instruct switching of the display format of the setting image (step S23). The display switching operation is performed using, for example, the direction keys 22 and enter key 23 of the remote controller 2, or the operation panel 15.

If the display switching operation is not performed (step S23; NO), the projector 1 moves to step S26.
When the display switching operation is performed (step S23; YES), the projector 1 changes the settings written in the setting data 122 in association with the setting item being displayed according to the display switching operation (step S24). After that, the projector 1 changes the display form of the setting image displayed in step S22 and updates the display (step S25). As a result, the display form of the setting image is switched from L-shaped display to normal OSD display, or vice versa. After that, the projector 1 moves to step S26.

In step S26, the projector 1 determines whether or not the operation using the setting image has been completed (step S26). If it is determined that the operation has not been completed (step S26; NO), the projector 1 returns to step S16.

If it is determined that the operation has been completed (step S26; YES), the projector 1 causes the image processing unit 16 to perform image processing that reflects the contents of the setting items set using the setting image, and changes the image being displayed. The image display is updated by reflecting the image processing (step S27). For example, when the set image is displayed in the normal OSD display, the projector 1 applies the set image processing to the first image P1 and updates the display of the first image P1 in step S27. For example, when the set image is displayed in an L-shaped display, in step S27, the projector 1 applies the set process to the reduced image P2 displayed in the first area 301, and displays the reduced image P2. Update.

Subsequently, the projector 1 ends displaying the setting image (step S28). As a result, the projector 1 enters a state in which the first image P1 is displayed in an area wider than the first area 301, as shown in FIG. 3A, for example.
The projector 1 causes the image processing unit 16 to perform image processing that reflects the contents of each setting item set using the setting image, and updates the display of the first image P1 (step S29). As a result, settings regarding the display image of the projector 1 are performed, the image processing unit 16 executes image processing or image adjustment according to the set function, and the display image after the image processing or image adjustment is displayed. .

Furthermore, if settings related to image processing or image adjustment functions are made using the settings image displayed in the normal OSD display in step S19, even if the contents of these settings are enabled while the settings image is being displayed. good. That is, while the setting image is normally displayed in the OSD display, the projector 1 performs image processing or image adjustment on the first image P1 based on the set contents using the setting image to change the first image P1. The display may be updated. The same applies when settings related to image processing or image adjustment functions are performed using the setting image displayed in an L shape in step S21 or S23.

[4. Another example of image display format]
With reference to FIGS. 3, 4, and 5, an example in which L-shaped display and normal OSD display are selected and executed has been described. and is not limited to. Another example of the display format will be explained below.

FIG. 6 is a diagram illustrating another example of transition of the display format by the projector 1.
FIG. 6(B) is a display form of the L-shaped display shown in FIG. 3(B). FIG. 6(D) shows another example of L-shaped display, and this display form is an inverted L-shaped display.

The inverted L-shaped display has a fourth area 304 along two different sides from the L-shaped display among the four sides forming the display area 300. In the inverted L-shaped display, a fourth area 304 different from the fifth area 305 is provided in the display area 300, and the reduced image P2 is displayed in the fourth area 304. The fourth area 304 and the fifth area 305 are, for example, areas that do not overlap with each other.

Similar to the second area 302, the fourth area 304 includes a function selection section 325, an explanation display section 327, and an operation image 328. The settings image displayed in the fourth area 304 corresponds to an example of the third settings image.

The projector 1 can be configured to switch between an L-shaped display and an inverted L-shaped display according to a user's operation using the operation unit 20 or the operation panel 15. Specifically, a configuration may be adopted in which normal OSD display, L-shaped display, and inverted L-shaped display can be switched by display switching operation (step S23), or while L-shaped display is being executed, L-shaped display An operation for switching between the display and the inverted L-shaped display may be accepted.

The shape of the setting image displayed together with the reduced image P2, that is, the shape of the second area 302, is not limited to the L-shape or the inverted L-shape. For example, a rectangular second area 302 may be arranged in the display area 300 along one of the sides of the display area 300. In this case, the second area 302 may be vertically long or horizontally long.

Further, the shape of the second region 302 may be a U-shape, and in this case, the direction of the U-shape is arbitrary. In either orientation, the first region 301 is arranged within the U-shaped second region 302. With this configuration, more information can be displayed in the second area 302.

FIG. 7 is an explanatory diagram of the operation of the projector 1, and shows an example of the operation when the projector 1 switches between an L-shaped display and an inverted L-shaped display.

When the projector 1 displays a setting image in one of the normal OSD display, L-shaped display, and inverted L-shaped display, the projector 1 generates the setting image by the image processing unit 16 under the control of the control unit 10 . The image processing unit 16 further generates display image data by combining the setting image and the first image P1 or the reduced image P2. When displaying either an L-shaped display or an inverted L-shaped display, the image processing unit 16 may generate an extended image 330 shown in FIG. 7.

The expanded image 330 includes a reduced image P2 generated by reducing the first image P1, an L-shaped setting image 331 displayed in the second area 302, and an inverted L-shaped setting image 331 displayed in the fourth area 304. This is an image that is a composite of the character shape setting images 332.

In FIG. 7, the range that can be displayed in the display area 300 is shown by virtual lines. Since the expanded image 330 is larger than the display area 300, the entire expanded image 330 cannot be displayed in the display area 300. The projector 1 moves the range displayed by the projection unit 17 of the extended image 330, for example, in the direction shown by arrow D in FIG. Specifically, the process of moving the extended image 330 is executed by the image processing unit 16. That is, after generating the extended image 330, the image processing section 16 cuts out a range of the extended image 330 to be displayed on the projection section 17, and outputs the image of the cut out range to the projection section 17.

By the image processing unit 16 generating the extended image 330, the projector 1 can quickly switch between L-shaped display and inverted L-shaped display. Further, the projector 1 may perform a display in which the image displayed by the projection unit 17 is moved as shown by arrow D when the user instructs to switch between L-shaped display and inverted L-shaped display. In this case, unlike the case where the display of the setting image is once ended and the display is switched between L-shaped display and inverted L-shaped display, the reduced image P2 is continuously displayed, so that the user's convenience can be further improved. You can expect it.

FIG. 8 is a diagram illustrating yet another example of the transition of the display format by the projector 1.
FIG. 8(A) and FIG. 8(B) are examples of display formats in which the setting image is displayed superimposed on the first image P1.

In the display form of FIG. 8A, the setting image 341 is placed over the first image P1 displayed in the entire display area 300. The settings image 341 is, for example, an image similar to the settings image 321 and the settings image 331. The setting image 341 has a shape along two adjacent sides among the four sides forming the display area 300, and can be said to have an L-shape. This display form is assumed to be an L-shaped superimposed display.

In the display form of FIG. 8B, the setting image 342 is placed over the first image P1 displayed in the entire display area 300. The settings image 342 is, for example, the same image as the settings image 341. The setting image 342 has a shape along two adjacent sides different from the setting image 341 among the four sides forming the display area 300. The shape of the setting image 341 can be called an inverted L shape. This display form is assumed to be an inverted L-shaped superimposed display.

In the L-shaped superimposed display and inverted L-shaped superimposed display, the setting images 341 and 342 are displayed superimposed on the first image P1, so the visibility of a part of the first image P1 decreases, but the first image P1 is reduced. There is a characteristic that it does not. This advantage is similar to the normal OSD display shown in FIG. 3(C).
For example, the projector 1 performs an L-shaped superimposed display and an inverted L-shaped superimposed display as variations of the normal OSD display. In this case, while displaying the setting image in the normal OSD display, the projector 1 changes the normal OSD display to an L-shaped superimposed display or an inverted L-shaped display according to the operation for switching the setting image using the operation unit 20 or the operation panel 15. Switch to superimposed display. Further, the projector 1 switches and displays an L-shaped superimposed display and an inverted L-shaped superimposed display according to the operation of the operating unit 20 or the operating panel 15.

Here, in the display area 300, the overlapping areas 351 and 352 overlap the setting images 341 and 342 in both the L-shaped overlapping display and the reverse L-shaped overlapping display. Therefore, even if the L-shaped superimposed display and the inverted L-shaped superimposed display are switched, the overlapping regions 351 and 352 remain covered by the setting images 341 and 342. Therefore, in order to improve the visibility of the overlapping areas 351 and 352, the setting images 341 and 342 may have shapes that do not overlap with the overlapping areas 351 and 352. For example, in at least one of the setting image 341 and the setting image 342, the area overlapping the overlapping area 351 and the overlapping area 352 may be left blank. In this case, the visibility of the display area 300 in the overlapping areas 351 and 352 is improved. Further, a color pattern may be displayed in at least one of the overlapping area 351 and the overlapping area 352 in both the setting image 341 and the setting image 342. In this case, it becomes easy to confirm the display color in the display area 300 while displaying the setting images 341 and 342. This configuration is useful, for example, when adjusting the display color of the first image P1.

[5. Effects, etc.]
As described above, the projector 1 of this embodiment can display setting images for making settings regarding the functions of the projector 1 in a plurality of different display formats. Display formats include normal OSD display and L-shaped display. Further, the display form may be an inverted L-shaped display. Further, the display form may include one or more of an L-shaped superimposed display and an inverted L-shaped superimposed display.

Therefore, a display format suitable for the function to be set is selected without the user being particularly conscious of it, so that the user can easily perform the settings.

Further, among the functions of the projector 1, some functions corresponding to the second function are normally associated with an OSD display. The second function is, for example, an adjustment function such as tracking adjustment, blanking adjustment, sharpness adjustment, and detail emphasis. Therefore, for functions for which it is appropriate for the user to set without reducing the size of the projector 1, the setting image is normally displayed on the OSD even if the user does not perform any particular operation. Therefore, a display format suitable for the function to be set is selected without the user being particularly conscious of it, so that the user can easily perform the settings.

Furthermore, some of the functions of the projector 1 can be switched between the L-shaped display and the normal OSD display by user operation. Therefore, the setting image can be displayed in the display format desired by the user.

Further, the projector 1 can be configured to be able to switch between an L-shaped display and an inverted L-shaped display by a user's operation. In this case, the relative display position of the set image and the reduced image P2 can be changed according to the installation environment of the projector 1, the location of the projection target 3, or the user's preference, and the user can more easily You can set the functions of projector 1.

Furthermore, the projector 1 may be configured to be able to display the setting image in an L-shaped superimposed display format. In this case, the area for displaying the setting image can be increased without significantly reducing the visibility of the first image P1. Therefore, more information can be displayed on the setting image than in normal OSD display. Furthermore, the projector 1 may be configured to switch between an L-shaped superimposed display and an inverted L-shaped superimposed display according to a user's operation. In this case, the area covered by the setting image in the first image P1 can be changed. Therefore, the user can more easily set the functions of the projector 1 according to the installation environment of the projector 1, the location of the projection target 3, or the user's preference.
