[0008] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not described in the independent claims are described as optional components.

[0009] In addition, each drawing is a schematic diagram and is not necessarily an exact illustration. In addition, the same components are denoted by the same reference numerals in each drawing.

[0010] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0011] (Embodiment) <Configuration and Function> First, a display system 1 according to the present embodiment will be described with reference to FIGS.

[0012] Fig. 1 is a schematic diagram showing a display system 1 according to an embodiment. Fig. 2 is a block diagram showing the display system 1 according to an embodiment. Fig. 3A is a schematic diagram showing a displayable area and a faulty area of ​​a display screen 10. Fig. 3B is another schematic diagram showing a displayable area and a faulty area of ​​the display screen 10. Fig. 4 is a diagram illustrating an example of a customization mode being executed in the display system 1 and a customization operation being performed.

[0013] As shown in FIG. 1, the display system 1 is a system for displaying a plurality of images on the display screen 10 of one or more display devices 9. Specifically, the display system 1 allows the display positions of the plurality of images to be set automatically or manually by a user on the display screen 10 of the one or more display devices 9. Furthermore, in the display system 1, if a portion of the display screen 10 fails, the display system 1 displays images in an area other than the failed portion. For example, the display system 1 is used in a vehicle 2 or the like equipped with one or more display devices 9, and even if a portion of the display screen 10 of one of the one or more display devices 9 fails, the one or more display devices 9 can cooperate to display a plurality of images excluding the failed portion.

[0014] In this embodiment, the multiple images are images displayed based on an application, and include, for example, information such as vehicle instruments, operating status of on-board equipment, navigation information, captured images, and surrounding vehicle information. The vehicle instruments include a speedometer, turn signal lights, warning lights, odometer, shift position, fuel gauge, water temperature gauge, etc. The on-board equipment includes, for example, an audio device, on-board lighting devices, and seat devices. The navigation information is information for providing the driver with route guidance to the current position and destination while driving the vehicle 2. The captured images are images of the surroundings of the vehicle 2 or the interior of the vehicle cabin captured by an imaging device mounted on the vehicle 2. The surrounding vehicle information is information indicating the presence, number, speed, and distance of other vehicles present around the vehicle 2.

[0015] Specifically, as shown in FIG. 2, the display system 1 includes one or more display devices 9, a display control device 20, and a notification unit 40.

[0016] [Display device 9] The display device 9 is a display such as a PC (Personal Computer) monitor such as a liquid crystal display, a car navigation system mounted on the vehicle 2, an electronic mirror system, a multi-information display, or a head-up display (HUD).

[0017] 1 illustrates, as the multiple display devices 9, a car navigation system 19a disposed in the center of the vehicle width, an electronic mirror system functioning as a left side mirror 19b and a right side mirror 19c, and multiple multi-information displays 19d, 19e, and 19f. These display devices 9 are arranged side by side so that the occupants of the vehicle 2 can view the multiple display devices 9 all at once.

[0018] When multiple display devices 9 are provided in the vehicle 2, two or more of the multiple display devices 9 can be controlled in a coordinated manner by the display system 1 to display a single image or to display individual images. The two or more display devices 9 are adjacent to or adjacent to each other. In FIG. 2 of this embodiment, the two or more display devices 9 include a first display device 9a and a second display device 9b. The first display device 9a and the second display device 9b differ in at least one of the model, performance (resolution, response speed, contrast ratio, etc.), size of the display screen 10, settings, etc. Furthermore, the two or more display devices 9 are controlled in a coordinated manner by a display control device, so that they can display an image with a consistent overall appearance even if the display devices 9 differ in at least one of physical size, resolution, brightness, and color tone.

[0019] [Display control device 20] 2, the display control device 20 controls the display of a plurality of images on the display screen 10 of one or more display devices 9. Specifically, when a part of the display screen 10 fails, the display control device 20 can control the display of images in a displayable area other than the failed area.

[0020] Here, the faulty area is an area on the display screen 10 of the display device 9 where an image cannot be displayed properly. The displayable area is an area on the display screen 10 of the display device 9 excluding the faulty area, and is an area where an image can be displayed properly. The faulty area and the displayable area are identified by their position coordinates on the display screen 10.

[0021] Specifically, the display control device 20 includes an acquisition unit 21 and a control unit 30.

[0022] The acquisition unit 21 acquires fault area information indicating a fault area in the display area of ​​FIG. 3A constructed on one or more display screens 10 that display images. For example, the acquisition unit 21 is a sensor, an input interface, or the like. Here, the display area is an area on the display screen 10 of the display device 9 that can display an image, and includes the entire area of ​​the display screen 10 that is not faulty, and a reconstructed displayable area, which will be described later.

[0023] If the acquisition unit 21 is a sensor, the sensor can acquire the failure area information by detecting a failure area on the display screen 10 of the display device 9. In this case, the sensor is a camera sensor or the like, and may have, for example, a detection unit and a failure area detection unit. The detection unit may detect one or more display screens 10 by capturing images of the one or more display screens 10. The failure area detection unit may detect an area in which no image is displayed on the one or more detected display screens 10 as the failure area.

[0024] Furthermore, when the acquisition unit 21 is an input interface, the input interface can acquire failure area information indicating the failure area by having an external device identify the failure area. The external device is, for example, an input terminal such as a smartphone or tablet terminal that can acquire the failure area information by a user inputting the failure area.

[0025] Then, the acquisition unit 21 can output the acquired failure area information to the control unit 30.

[0026] Based on the failure area information acquired from the acquisition unit 21, the control unit 30 can specify the displayable area obtained by excluding the failure area from the display area.

[0027] Specifically, the control unit 30 has a display range management unit 31, a display screen generation unit 32, and a display screen drawing unit 33. In this case, the control unit 30 only needs to have at least the display range management unit 31.

[0028] The display range management unit 31 manages the display range based on the failure area information acquired from the acquisition unit 21. Specifically, the display range management unit 31 identifies a displayable area excluding the failure area from the display area. At this time, the display range management unit 31 defines the failure area by surrounding the entire failure area with a predetermined frame. For example, the predetermined frame is a circle, a rectangle, a polygon, or the like. The display range management unit 31 manages the display range by reconstructing the displayable area so that an image is displayed in the identified displayable area. In other words, the display range management unit 31 reconstructs the displayable area from the display area so that an image is displayed only in the displayable area. The display range management unit 31 outputs the reconstructed displayable area to the display screen drawing unit 33 and the notification unit 40. The display range management unit 31 may be an example of a control unit.

[0029] Here, the displayable area is an area in the display area constructed on the display screen 10 of the display device 9 where an image can be displayed, excluding the faulty area, as shown in (a) of Fig. 3A. The faulty area is an area in the display screen 10 of the display device 9 where an image cannot be displayed properly due to a fault.

[0030] The displayable area may also be reconstructed as follows:

[0031] First, the display range management unit 31 may divide the identified displayable area into multiple displayable areas, reconstruct the multiple displayable areas so that images can be displayed in them, and output the multiple divided and reconstructed displayable areas. For example, as shown in FIG. 3A(b), a portion of the display screen 10 may be divided due to a failure. In this case, it is necessary to reconstruct the multiple displayable areas to fit the divided display area. That is, the display range management unit 31 reconstructs the display area so that images can be displayed in the multiple displayable areas obtained by dividing the display area excluding the failed area. In the example of FIG. 3A(b), the identified displayable area is divided into two reconstructed displayable areas that are independent of each other. In this case, different images can be displayed independently in each of the two displayable areas.

[0032] 3A(c), when the first display screen 10a and the second display screen 10b of two or more display screens 10 are arranged side by side, the display range management unit 31 may identify a first displayable area and a second displayable area by excluding a faulty area from the first display area of ​​the first display screen 10a and the second display area of ​​the second display screen 10b, reconstruct the first displayable area and the second displayable area so that images are displayed in the identified first displayable area and the second displayable area, and output the reconstructed first displayable area and the reconstructed second displayable area. For example, when the first display screen 10a and the second display screen 10b are arranged side by side so as to be contiguous, if a faulty area is formed in at least the first display screen 10a or the second display screen 10b, the display range management unit 31 may identify a first displayable area and a second displayable area by excluding the faulty area from the first display area and the second display area. Then, the display range management unit 31 reconstructs the identified first displayable area and the second displayable area.

[0033] In the example of (c) in Fig. 3A, a faulty area is formed on the second display screen 10b. In this case, the display range management unit 31 reconstructs a part of the first display area as a first displayable area according to the size of the faulty area on the second display screen 10b, and reconstructs a second displayable area by combining the remaining display area of ​​the first display area with the displayable area of ​​the second display area excluding the faulty area. Even in this case, different images can be displayed independently in the two displayable areas, but an image is displayed across both the first display screen 10a and the second display screen 10b in the second displayable area.

[0034] 3A (d), when the first display screen 10a and the second display screen 10b of two or more display screens 10 are arranged side by side, the display range management unit 31 may identify one displayable area by excluding the faulty area from the combined display area of ​​the first display screen 10a and the second display area of ​​the second display screen 10b, reconstruct the image to be displayed in the identified one displayable area, and output the reconstructed one displayable area. For example, when the first display screen 10a and the second display screen 10b are arranged side by side so as to be contiguous, if a faulty area is formed in at least the first display screen 10a or the second display screen 10b, the display range management unit 31 may identify one displayable area by excluding the faulty area from the combined display area of ​​the first display area and the second display area. The display range management unit 31 reconstructs the identified one displayable area. 3A(d), since a failure area is formed on the second display screen 10b, the display range management unit 31 combines the first display area with the displayable area of ​​the second display area excluding the failure area to form a single reconstructed displayable area. In this case, an image is displayed across a single displayable area, that is, the first display screen 10a and the second display screen 10b.

[0035] Furthermore, as shown in (a) of Figure 3B, the display range management unit 31 may reconstruct the identified displayable area while maintaining the aspect ratio. In the example of (a) of Figure 3B, if the area excluding the failed area from the display area is set as the displayable area, the aspect ratio of the displayable area will differ from the aspect ratio of the display area, and the image displayed in the displayable area will expand or contract in a certain direction. For this reason, the display range management unit 31 may reconstruct the displayable area while maintaining the aspect ratio of the display area before reconstruction.

[0036] 3B(b), when two or more display screens 10 are arranged, a first display screen 10a and a second display screen 10b, the display range management unit 31 identifies a first displayable area, which is the first display area of ​​the first display screen 10a excluding the failed area, based on the failed area information of the first display screen 10a. The display range management unit 31 divides the first display area into the identified first displayable area and the failed area, reconstructs the first display area, and outputs an image corresponding to the reconstructed first displayable area from the first display screen 10a, and outputs an image corresponding to the failed area from the reconstructed second display area of ​​the second display screen 10b. For example, if a portion of the first display screen 10a fails, the display range management unit 31 displays a portion of the image corresponding to the first displayable area excluding the failed area, and displays the remaining portion of the image corresponding to the failed area in the second display area of ​​the second display screen 10b. As a result, by arranging the first display screen 10a and the second display screen 10b side by side, it is possible to reproduce and display the image in the first display area that could have been displayed if the first display screen 10a had not malfunctioned.

[0037] Furthermore, as shown in (d) of FIG. 3B, the display range management unit 31 may identify a displayable area excluding only the failure area from the display area based on the failure area information acquired from the acquisition unit 21. For example, the display range management unit 31 may reconstruct the entire display area excluding the failure area as a single displayable area. In another example, as shown in (c) of FIG. 3B, the display range management unit 31 may divide the identified displayable area into multiple displayable areas and reconstruct the display area. In other words, the display range management unit 31 may reconstruct the entire display area excluding the failure area as a displayable area.

[0038] 2, display screen generation unit 32 generates drawing commands for causing display screen drawing unit 33 to execute drawing processing in accordance with the operation of an application. Display screen generation unit 32 outputs the generated drawing commands to display screen drawing unit 33 via display range management unit 31.

[0039] Display screen drawing unit 33 acquires drawing commands for drawing images of applications and the like generated by display screen generation unit 32. Display screen drawing unit 33 executes drawing processing that adjusts the brightness (luminosity), contrast, gamma value, color tone, etc. of the image to be displayed in the displayable area based on the drawing commands acquired from display screen generation unit 32 via display range management unit 31 and the reconstructed displayable area acquired from display range management unit 31. Display screen drawing unit 33 then outputs the image for which the drawing processing has been executed to display device 9 so that it is displayed in the reconstructed displayable area.

[0040] As a result, even if a faulty area is formed on the display screen 10, the display control device 20 can display an image in a displayable area reconstructed by excluding the faulty area from the display area.

[0041] [Notification section 40] The notification unit 40 is, for example, a communication interface connected to a network so as to be able to communicate with it, a display monitor capable of displaying images, a speaker capable of outputting sound, etc. When the notification unit 40 acquires the reconstructed displayable area from the display range management unit 31, it outputs a message indicating that a faulty area exists and that the display area on the display device 9 will be changed.

[0042] [Customize display screen 10] In this embodiment, if the display screen 10 fails, the display system 1 executes the customization mode, thereby appropriately setting the images to be displayed on the multiple display devices 9. The customization mode may also be executed even if the display screen 10 does not fail. When the display system 1 executes the customization mode, a customized image is displayed on some of the multiple display devices 9, as shown in FIG. 4 . The user can customize the part images, their placement positions, sizes, and display formats for executing each application on the customized image according to their preferences. Applications are associated with, for example, part images related to vehicle instruments such as vehicle speed and engine RPM, part images related to the operating status of in-vehicle devices such as the volume of an audio system, and part images related to navigation information. The display content customized by the user can be displayed on the display screens 10 of the multiple display devices 9 installed in the vehicle 2. At this time, if a part of the display screen 10 fails, the control unit 30 displays an image that has been rendered in the reconstructed displayable area, as shown in the actual display shown in FIG. 4 .

[0043] <Processing operation> The processing operations of the display control device 20, the display control method, and the program according to this embodiment will be described.

[0044] (Example 1) First, a case where a part of one display screen 10 breaks down will be described with reference to FIG.

[0045] FIG. 5 is a flowchart showing a first operation example of the display system 1 according to the embodiment.

[0046] First, the acquisition unit 21 acquires failure area information indicating a failure area among display areas constructed on one or more display screens 10 that display images (S11). The acquisition unit 21 outputs the acquired failure area information to the control unit 30.

[0047] Next, the display range management unit 31 of the control unit 30 specifies a displayable area excluding the failure area from the display area based on the failure area information acquired from the acquisition unit 21. The display range management unit 31 determines whether the display area matches the specified displayable area (S12).

[0048] If the display range management unit 31 determines that the display area matches the identified displayable area (YES in S12), it ends the processing operation of the flowchart and then returns to step S11 to repeat the operation processing.

[0049] On the other hand, if the display range management unit 31 determines that the display area does not match the identified displayable area (NO in S12), it reconstructs the image so that it is displayed in the identified displayable area (S13). The display range management unit 31 outputs the reconstructed displayable area to the display screen drawing unit 33 and the notification unit 40. The display screen drawing unit 33 acquires a drawing command for drawing an image of an application or the like generated by the display screen generation unit 32 and the reconstructed displayable area from the display range management unit 31. The display screen drawing unit 33 performs drawing processing that adjusts the brightness (luminosity), contrast, gamma value, color tone, etc. of the image to be displayed in the displayable area based on the drawing command from the display screen generation unit 32 and the displayable area reconstructed by the display range management unit 31. The display screen drawing unit 33 outputs the image for which the drawing processing has been performed to the display device 9 so that it is displayed in the reconstructed displayable area.

[0050] Next, when the notification unit 40 acquires the reconstructed displayable area from the display range management unit 31, it outputs a message that a faulty area exists and that the display area on the display device 9 should be changed (S14). This allows the user to take action such as repairing or replacing the display device 9, or continuing to use it as is.

[0051] Then, the display system 1 ends the processing operation of the flowchart in Fig. 5. Then, the process returns to step S11 and repeats the operation processing.

[0052] Furthermore, when a failure occurs in the reconstructed displayable area, the display control device 20 can use the reconstructed displayable area as the display area, and further construct a displayable area excluding the failed area.

[0053] In step S12, the display range management unit 31 may determine whether or not it has acquired fault area information, instead of determining whether or not the display area matches the identified displayable area. If it is determined that it has acquired fault area information, the process may proceed to step S13, and if it is determined that it has not acquired fault area information, the flowchart may end.

[0054] (Example 2) Next, an example of operation when dividing the identified displayable area into a plurality of displayable areas will be described with reference to FIG.

[0055] FIG. 6 is a flowchart showing a second operation example of the display system 1 according to the embodiment.

[0056] The same processes as those in FIG. 5 are denoted by the same reference numerals and the description thereof will be omitted where appropriate.

[0057] First, after steps S11 and S12, if the result of step S12 is NO, the display screen rendering unit 33 divides the identified displayable area into multiple displayable areas and reconstructs them so as to display images (S13a). The display screen rendering unit 33 acquires a drawing command from the display screen generation unit 32 and the multiple displayable areas reconstructed from the display range management unit 31. The display screen rendering unit 33 performs drawing processing on multiple images to be displayed in the multiple displayable areas based on the drawing command from the display screen generation unit 32 and the multiple displayable areas reconstructed by the display range management unit 31. The display screen rendering unit 33 outputs each of the multiple images for which drawing processing has been performed to the display device 9 so as to correspond to each of the multiple reconstructed displayable areas.

[0058] Then, the display system 1 goes through step S14 to complete the processing operation of the flowchart in Fig. 6. Then, the process returns to step S11 to repeat the operation processing.

[0059] (Example 3) Next, using Figure 7, we will explain an example of operation when a first display screen 10a and a second display screen 10b are arranged side by side as an example of multiple display screens 10, and a faulty area is removed from the first display area of ​​the first display screen 10a and the second display area of ​​the second display screen 10b.

[0060] FIG. 7 is a flowchart showing a third operation example of the display system 1 according to the embodiment.

[0061] The same processes as those in FIG. 5 are denoted by the same reference numerals and the description thereof will be omitted where appropriate.

[0062] First, the acquisition unit 21 acquires failure area information from the first display screen 10a and / or the second display screen 10b, which display different images from each other (S11). The acquisition unit 21 outputs the acquired failure area information to the control unit 30.

[0063] Next, the display range management unit 31 of the control unit 30 identifies a first displayable area and a second displayable area, which are obtained by excluding the failure area from the first display area of ​​the first display screen 10a and the second display area of ​​the second display screen 10b, based on the failure area information acquired from the acquisition unit 21. For example, as shown in (c) of FIG. 3A, if a failure area is formed on the second display screen 10b, the display range management unit 31 identifies the first displayable area of ​​the first display screen 10a and identifies a second displayable area, which is obtained by excluding the failure area from the second display area of ​​the second display screen 10b, based on the failure area information. The display range management unit 31 determines whether the display area matches the identified displayable area. Specifically, the display range management unit 31 determines whether the first display area matches the identified first displayable area and whether the second display area matches the identified second displayable area (S12b).

[0064] If the display range management unit 31 determines that the display area matches the specified displayable area, that is, if the first display area matches the specified first displayable area and the second display area matches the specified second displayable area (YES in S12b), the flow chart ends. Then, the process returns to step S11 and the operation process is repeated.

[0065] On the other hand, if the display range management unit 31 determines that the display area does not match the specified displayable area, it reconstructs the display so that the image is displayed in the specified displayable area. That is, if the first display area does not match the specified first displayable area and / or the second display area does not match the specified second displayable area (NO in S12b), it reconstructs the display so that the image is displayed in two displayable areas obtained by excluding the faulty area from the first display area and the second display area (S13b). Specifically, if the result in step S12b is NO, the display range management unit 31 reconstructs a part of the first display area to display the image in accordance with the size of the faulty area on the second display screen 10b, and reconstructs the display so that the image is displayed in the area obtained by combining the remaining display area of ​​the first display area and the displayable area of ​​the second display area excluding the faulty area (S13b). The display range management unit 31 sets a part of the first display area as a reconstructed first displayable area, and sets a reconstructed second displayable area by combining the remaining display area of ​​the first display area with the displayable area of ​​the second display area excluding the failed area. The display screen drawing unit 33 acquires drawing commands for drawing images of applications, etc. generated by the display screen generation unit 32, and the reconstructed first displayable area and the reconstructed second displayable area from the display range management unit 31. The display screen drawing unit 33 performs drawing processing of images to be displayed in the reconstructed first displayable area and the reconstructed second displayable area, based on the drawing commands of the display screen generation unit 32 and the first displayable area and the reconstructed second displayable area reconstructed by the display range management unit 31. The display screen drawing unit 33 outputs an image obtained by performing drawing processing on the reconstructed first displayable area, and outputs an image obtained by performing drawing processing on the reconstructed second displayable area. 3A(c), the display screen drawing unit 33 outputs to the first display device 9a the image on which the drawing process has been performed in the constructed first displayable area and a part of the image on which the drawing process has been performed in the reconstructed second displayable area. The display screen drawing unit 33 also outputs to the second display device 9b the remaining image on which the drawing process has been performed in the reconstructed second displayable area.

[0066] Then, the display system 1 goes through step S14 to complete the processing operation of the flowchart in Fig. 7. Then, the process returns to step S11 to repeat the operation processing.

[0067] (Example 4) Next, in the case where a first display screen 10a and a second display screen 10b are arranged as an example of a plurality of display screens 10, an example of operation when a faulty area is removed from a single display area that is the combination of the first display area of ​​the first display screen 10a and the second display area of ​​the second display screen 10b will be described using Figure 8.

[0068] FIG. 8 is a flowchart showing a fourth operation example of the display system 1 according to the embodiment.

[0069] The same processes as those in FIG. 5 are denoted by the same reference numerals and the description thereof will be omitted where appropriate.

[0070] First, the acquisition unit 21 acquires failure area information from the first display screen 10a and / or the second display screen 10b (S11). The acquisition unit 21 outputs the acquired failure area information to the control unit 30.

[0071] Next, the display range management unit 31 of the control unit 30 identifies one displayable area by excluding the failure area from one display area, based on the failure area information acquired from the acquisition unit 21. For example, as shown in (d) of FIG. 3A, if a failure area is formed on the second display screen 10b, the display range management unit 31 identifies one displayable area by combining the first display area and the displayable area by excluding the failure area from the second display area, based on the failure area information. The display range management unit 31 determines whether the one display area matches the identified one displayable area (S12c).

[0072] If the display range management unit 31 determines that one display area matches one identified displayable area (YES in S12c), it ends the flowchart and then returns to step S11 to repeat the operation process.

[0073] On the other hand, if the display range management unit 31 determines that the one display area does not match the one identified displayable area (NO in S12c), it reconstructs the one identified displayable area so that the image is displayed in that one displayable area (S13c). The display screen drawing unit 33 acquires a drawing command for drawing an image of an application or the like generated by the display screen generation unit 32 and the one reconstructed displayable area from the display range management unit 31. The display screen drawing unit 33 performs drawing processing of an image to be displayed in the one reconstructed displayable area based on the drawing command of the display screen generation unit 32 and the one displayable area reconstructed by the display range management unit 31. The display screen drawing unit 33 outputs to the first display device 9a and the second display device 9b so that the image for which the drawing processing has been performed is displayed in the one reconstructed displayable area.

[0074] Then, the display system 1 goes through step S14 to complete the processing operation of the flowchart in Fig. 8. Then, the process returns to step S11 to repeat the operation processing.

[0075] (Example 5) Next, an example of operation when a first display screen 10a and a second display screen 10b are arranged and an image corresponding to a faulty area on the first display screen 10a is output from the reconstructed second display area of ​​the second display screen 10b will be described with reference to Fig. 9. The second display screen 10b is a display screen 10 of a terminal device such as a tablet terminal or smartphone that is separate and independent from the first display screen 10a.

[0076] FIG. 9 is a flowchart showing a fifth operation example of the display system 1 according to the embodiment.

[0077] The same processes as those in FIG. 5 are denoted by the same reference numerals and the description thereof will be omitted where appropriate.

[0078] First, the acquisition unit 21 acquires failure area information from the first display screen 10a that displays different images (S11). The acquisition unit 21 outputs the acquired failure area information to the control unit 30.

[0079] Next, the display range management unit 31 of the control unit 30 specifies a first displayable area obtained by excluding the failure area from the first display area of ​​the first display screen 10a, based on the failure area information acquired from the acquisition unit 21. The display range management unit 31 determines whether the first display area matches the specified first displayable area (S12d).

[0080] If the display range management unit 31 determines that the first display area matches the identified first displayable area (YES in S12d), it ends the flow chart, and then returns to step S11 to repeat the operation process.

[0081] On the other hand, if the display range management unit 31 determines that the first display area does not match the identified first displayable area (NO in S12d), it divides the first display area into the identified first displayable area and the failed area and reconstructs them (S13d). That is, the display range management unit 31 outputs the reconstructed first displayable area and the second display area of ​​the second display screen 10b reconstructed to correspond to the failed area. The display screen drawing unit 33 acquires drawing commands for drawing images of applications, etc. generated by the display screen generation unit 32, and the reconstructed first displayable area and the reconstructed second display area of ​​the second display screen 10b from the display range management unit 31. Based on the drawing commands from the display screen generation unit 32, the reconstructed first displayable area, and the reconstructed second display area of ​​the second display screen 10b, the display screen drawing unit 33 draws a part of the image in the reconstructed first displayable area and the rest of the image in the reconstructed second display area of ​​the second display screen 10b. In the case of (b) of Figure 3B, the display screen drawing unit 33 outputs to the first display device 9a so that a part of the image on which the drawing process has been performed is displayed in the reconstructed first displayable area, and outputs to the second display screen 10b so that the remaining image on which the drawing process has been performed is displayed in the reconstructed second display area of ​​the second display screen 10b.

[0082] Then, the display system 1 goes through step S14 to complete the processing operation of the flowchart in Fig. 9. Then, the process returns to step S11 to repeat the operation processing.

[0083] Furthermore, in steps S13, S13a, S13b, S13c, and S13d of the above-described operation examples 1 to 5, the display range management unit 31 may further reconstruct the identified displayable area while maintaining the aspect ratio.

[0084] Furthermore, in steps S13, S13a, S13b, S13c, and S13d of the above-described operation examples 1 to 5, the display range management unit 31 may identify a displayable area excluding only the failure area from the display area based on the failure area information acquired from the acquisition unit 21, and reconstruct all display areas excluding the failure area as a single displayable area.

[0085] <Action and effect> Next, the effects of the display control device 20, the display control method, and the program according to this embodiment will be described.

[0086] As described above, the display control device 20 according to this embodiment includes an acquisition unit 21 that acquires faulty area information indicating faulty areas within a display area constructed on one or more display screens 10 that display images, and a control unit 30 that, based on the faulty area information acquired by the acquisition unit 21, identifies a displayable area excluding the faulty area from the display area, reconstructs the identified displayable area so that an image is displayed in the identified displayable area, and outputs the reconstructed displayable area.

[0087] According to this, even if a failure occurs in one display screen 10, it is possible to reconstruct the displayable area by excluding the failed area from the display area of ​​the display screen 10. As a result, an image can be displayed in the reconstructed displayable area, so that a partial failure in one display screen 10 does not have to be treated as a failure of the entire display screen 10.

[0088] Therefore, the display control device 20 can prevent the display area from being extremely narrowed, and can effectively utilize the displayable area other than the failure area.

[0089] In addition, the display control method according to this embodiment includes acquiring faulty area information indicating a faulty area among the display areas constructed on one or more display screens 10 that display images, identifying a displayable area excluding the faulty area from the display area based on the acquired faulty area information, reconstructing the displayable area so as to display the image in the identified displayable area, and outputting the reconstructed displayable area.

[0090] This display control method also provides the same effects as those described above.

[0091] The program according to the present embodiment is a program that causes a computer to execute a display control method.

[0092] This program also provides the same effects as those described above.

[0093] Furthermore, in the display control device 20 according to this embodiment, the control unit 30 divides and reconstructs the identified displayable area into a plurality of displayable areas, and outputs the plurality of divided and reconstructed displayable areas.

[0094] This allows multiple displayable areas to be reconstructed and formed on one display screen 10, as shown in (b) of Figure 3A, so that even if the display screen 10 breaks down, multiple images can be displayed on one display screen 10.

[0095] Furthermore, even if any part of the display screen 10 fails, by dividing it into multiple displayable areas, the failed area can be minimized, and the displayable areas other than the failed area can be used more effectively.

[0096] Furthermore, in the display control device 20 according to this embodiment, when a first display screen 10a and a second display screen 10b are arranged among two or more display screens 10, the control unit 30 identifies a first displayable area and a second displayable area excluding the faulty area from the first display area of ​​the first display screen 10a and the second display area of ​​the second display screen 10b, reconstructs the identified first displayable area and second displayable area so that an image is displayed in the identified first displayable area and second displayable area, and outputs the reconstructed first displayable area and the reconstructed second displayable area.

[0097] 3A(c), when the first display screen 10a and the second display screen 10b are arranged side by side, the reconstructed first and second displayable areas can be formed across the first and second display screens 10a, 10b. Furthermore, it is possible to prevent the image on the display screen 10 where a faulty area is formed from being displayed smaller than the original image on the first or second display screen 10a, 10b. Therefore, even if a faulty area is formed, the image size can be balanced across the reconstructed displayable areas.

[0098] Furthermore, in the display control device 20 according to this embodiment, when a first display screen 10a and a second display screen 10b are arranged among two or more display screens 10, the control unit 30 identifies one displayable area excluding the faulty area from one display area formed by combining the first display area of ​​the first display screen 10a and the second display area of ​​the second display screen 10b, reconstructs the identified one displayable area so that an image is displayed in the identified one displayable area, and outputs the reconstructed one displayable area.

[0099] According to this, when the first display screen 10a and the second display screen 10b are arranged side by side as shown in (d) of Figure 3A, even if a faulty area is formed on one of the first display screen 10a and the second display screen 10b, one displayable area can be reconstructed.

[0100] Furthermore, in the display control device 20 according to this embodiment, the control unit 30 reconstructs the identified displayable area while maintaining the aspect ratio before reconstruction.

[0101] This allows the displayable area to be reconstructed while maintaining the aspect ratio, as shown in FIG. 3B(a), thereby preventing the image from expanding or contracting in the vertical or horizontal direction.

[0102] Furthermore, in the display control device 20 according to this embodiment, when a first display screen 10a and a second display screen 10b are arranged among two or more display screens 10, the control unit 30 identifies a first displayable area obtained by excluding the failure area from the first display area of ​​the first display screen 10a based on the failure area information of the first display screen 10a, divides the first display area into the first displayable area and the failure area, and reconstructs the first display area, and outputs an image corresponding to the reconstructed first displayable area from the first display screen 10a, and outputs an image corresponding to the failure area from the reconstructed second display area of ​​the second display screen 10b.

[0103] 3B(b), an image corresponding to the failed area can be displayed on the second display screen 10b. As a result, an image corresponding to the reconstructed first displayable area and an image corresponding to the failed area can be displayed together, like the image of the first display area that was displayed before the failure.

[0104] Furthermore, in the display control device 20 according to this embodiment, the control unit 30 specifies a displayable area that is the display area excluding only the failure area, based on the failure area information acquired by the acquisition unit 21.

[0105] This allows the entire area other than the faulty area to be used as a displayable area, as shown in (c) and (d) of Figure 3B, making it possible to more effectively utilize the displayable area other than the faulty area.

[0106] (First Modification of the Embodiment) This modified example differs from the embodiment in that, when the faulty area occupies a predetermined percentage or more of the display area, fault information indicating that the display screen 10 is faulty is output. Unless otherwise specified, the other configurations of this embodiment are the same as those of the embodiment, and the same components are assigned the same reference numerals and detailed description of the configurations will be omitted.

[0107] First, the display system 1 of this modified example will be described with reference to FIG.

[0108] FIG. 10 is a schematic diagram showing a case where the faulty area of ​​the display screen 10 occupies a predetermined percentage or more of the display area.

[0109] In this modification, the display range management unit 31 may output failure information indicating that the display screen 10 is malfunctioning when the failure area indicated in the failure area information acquired from the acquisition unit 21 occupies a predetermined percentage or more of the display area. For example, if the failure area occupies a predetermined percentage or more of the display area, the displayable area becomes small, so even if an image is displayed, it may be difficult for the user to see, and the user may not be able to recognize important information. For this reason, the display range management unit 31 may output failure information to alert those around it when the failure area occupies a predetermined percentage or more of the display area.

[0110] In this modified example, the processing operation when the failure area occupies a predetermined percentage or more of the display area will be described with reference to FIG.

[0111] FIG. 11 is a flowchart showing the processing operation of the display system 1 according to the first modification of the embodiment.

[0112] After first going through step S11, the display range management unit 31 determines whether or not the failure area occupies a predetermined proportion or more of the display area (S21).

[0113] If the display range management unit 31 determines that the faulty area occupies a predetermined percentage or more of the display area (YES in S21), it sets the entire display screen 10 as a non-display screen (S15). The display range management unit 31 outputs the fault information to the notification unit 40. As a result, the notification unit 40 notifies the user of the fault information (S16), allowing the user to take action such as repairing or replacing the display device 9. Then, the processing operation of the flowchart in FIG. 11 ends, and the process returns to step S11 and repeats the operation processing.

[0114] On the other hand, if the display range management unit 31 determines that the failure area does not occupy a predetermined proportion or more of the display area (NO in S21), it goes through steps S12 to S14 and ends the processing operation of the flowchart in Fig. 11. Then, it returns to step S11 and repeats the operation processing.

[0115] In addition, in step S13 of FIG. 11 of this modified example, the display range management unit 31 may further reconstruct the identified displayable area while maintaining the aspect ratio.

[0116] Furthermore, in step S13 of Figure 11 of this modified example, the display range management unit 31 may identify a displayable area excluding only the failure area from the display area based on the failure area information acquired from the acquisition unit 21, and reconstruct all display areas excluding the failure area as a single displayable area.

[0117] In the display control device 20 according to this modified example, if the fault area indicated in the fault area information acquired by the acquisition unit 21 occupies a predetermined percentage or more of the display area, the control unit 30 outputs fault information indicating that the display screen 10 is faulty.

[0118] According to this, if the area occupies more than a certain percentage, the displayable area becomes too small and the displayed image also becomes too small, so by outputting fault information, the user can be prompted to consider replacement or repair.

[0119] (Modification 2 of the embodiment) This modified example differs from the embodiment in that fault information is output when the displayable area is less than a predetermined size. Unless otherwise specified, the other configurations in this embodiment are the same as those in the embodiment, and the same components are assigned the same reference numerals and detailed descriptions of the configurations are omitted.

[0120] First, the display system 1 of this modified example will be described with reference to FIG.

[0121] FIG. 12 is a schematic diagram showing a case where the displayable area is smaller than a predetermined size.

[0122] In this modification, the display range management unit 31 may output malfunction information indicating that the display screen 10 is malfunctioning if the displayable area is smaller than a predetermined size. A malfunction smaller than a predetermined size refers to a case where the ratio of the vertical to horizontal dimensions of the displayable area is smaller than a predetermined size, or a case where the number of vertical or horizontal pixels of the displayable area is smaller than a predetermined size. For example, if the displayable area is smaller than a predetermined size, the displayable area may become smaller or have a distorted shape that is stretched horizontally or vertically, making it difficult for the user to see displayed images or preventing the user from recognizing important information. For this reason, the display range management unit 31 may output malfunction information to alert those around the displayable area if the displayable area is smaller than a predetermined size.

[0123] In this modified example, the processing operation when the displayable area is smaller than a predetermined size will be described with reference to FIG.

[0124] FIG. 13 is a flowchart showing the processing operation of the display system 1 according to the second modification of the embodiment.

[0125] After first going through step S11, the display range management unit 31 determines whether the displayable area is smaller than a predetermined size (S31).

[0126] If the display range management unit 31 determines that the displayable area is less than a predetermined size (YES in S31), it sets the entire display screen 10 as a non-display screen (S15). The display range management unit 31 outputs the malfunction information to the notification unit 40. As a result, the notification unit 40 notifies the user of the malfunction information (S16), allowing the user to take action such as repairing or replacing the display device 9.

[0127] Then, the processing operation of the flowchart in FIG. 13 ends, and the process returns to step S11 to repeat the processing operation.

[0128] On the other hand, if the display range management unit 31 determines that the displayable area is not smaller than the predetermined size (NO in S31), it goes through steps S12 to S14 and ends the processing operation of the flowchart in Fig. 13. Then, it returns to step S11 and repeats the operation processing.

[0129] In addition, in step S13 of FIG. 13 of this modified example, the display range management unit 31 may further reconstruct the identified displayable area while maintaining the aspect ratio.

[0130] Furthermore, in step S13 of Figure 13 of this modified example, the display range management unit 31 may identify a displayable area excluding only the failure area from the display area based on the failure area information acquired from the acquisition unit 21, and reconstruct all display areas excluding the failure area as a single displayable area.

[0131] In the display control device 20 according to this modified example, when the displayable area is smaller than a predetermined size, the control unit 30 outputs malfunction information indicating that the display screen 10 is malfunctioning.

[0132] According to this, if the displayable area is less than a predetermined size, the displayable area becomes too small or the displayable area becomes distorted by being stretched horizontally or vertically, making it difficult to see the image. For this reason, by outputting the fault information, the user can be prompted to consider replacement or repair.
