[0010] The following detailed description of exemplary embodiments will be given with reference to the accompanying drawings. In the drawings used in the following description, the scale has been appropriately changed so that the illustrated elements can be clearly seen.

[0011] FIG. 1 illustrates a vehicle 20 equipped with a display control system 10 according to an embodiment. The vehicle 20 is an example of a moving body. A plurality of seats are installed in a passenger compartment 21 of the vehicle 20. The plurality of seats include a driver's seat 22 and a passenger seat 23. The driver's seat 22 is a seat in which the driver of the vehicle 20 sits. The passenger seat 23 is a seat in which a passenger sits. The driver is an example of a first occupant. The passenger is an example of a second occupant.

[0012] 2 illustrates an example of the functional configuration of a display control system 10 according to an embodiment. The display control system 10 includes a first display device 11 and a display control device 13.

[0013] 1, the first display device 11 is installed in the passenger compartment 21. The first display device 11 has a screen capable of displaying content including images. Specifically, the first display device 11 is placed in a position where the content can be viewed by both the driver seated in the driver's seat 22 and the passenger seated in the passenger seat 23.

[0014] 2, the display control device 13 includes an input interface 131. The input interface 131 is configured as a hardware interface that receives first image data D1 from a first mobile device 31. The first mobile device 31 is a mobile device carried by the driver of the vehicle 20. The first mobile device 31 includes a screen that can display first content C1 including an image. The first image data D1 corresponds to the first content C1.

[0015] The first image data D1 may be in the form of analog data or digital data depending on the specifications of the first mobile device 31. When the first image data D1 is in the form of analog data, the input interface 131 is provided with an appropriate conversion circuit including an A / D converter. This description also applies to other data and signals that can be accepted by the input interface 131, which will be described later.

[0016] The display control device 13 includes a processor 132 and an output interface 133. The processor 132 is configured to output, from the output interface 133, a first display control signal DC1 that causes the first content C1 to be displayed on the screen of the first display device 11. The first display control signal DC1 may be an analog signal or a digital signal depending on the specifications of the first display device 11.

[0017] The output interface 133 is configured as a hardware interface capable of outputting the first display control signal DC1. If the first display control signal DC1 is in the form of an analog signal, the output interface 133 includes an appropriate conversion circuit including a D / A converter. This description also applies to other signals that can be output by the output interface 133, which will be described later.

[0018] That is, as illustrated in FIG. 3, the display control device 13 is configured to mirror the first content C1 displayed on the screen of the first mobile device 31 onto the screen of the first display device 11.

[0019] As illustrated in FIG. 2, the input interface 131 is configured to be able to accept second image data D2 from the second mobile device 32. The second mobile device 32 is a mobile device carried by a passenger of the vehicle 20. As illustrated in FIG. 3, the second mobile device 32 has a screen capable of displaying second content C2 including an image. The second image data D2 corresponds to the second content C2. The second image data D2 may be in the form of analog data or digital data depending on the specifications of the second mobile device 32.

[0020] 2 and 3, the display control system 10 includes a user interface 14. The user interface 14 is configured to receive a first instruction from the driver of the vehicle 20 requesting mirroring of the second content C2 on the first display device 11. The user interface 14 is configured to output a first request signal RQ1 corresponding to the first instruction. The first request signal RQ1 may be an analog signal or a digital signal depending on the specifications of the user interface 14.

[0021] The input interface 131 of the display control device 13 is configured to be able to accept a first request signal RQ1 as well. Based on the first request signal RQ1, the processor 132 changes the first display control signal DC1 output from the output interface 133 so as to display the second content C2 on the screen of the first display device 11. As a result, as illustrated in Fig. 4, the screen of the first display device 11 switches from a state in which the first content C1 is mirrored to a state in which the second content C2 is mirrored.

[0022] 5 , a passenger in the vehicle 20 who is carrying the second mobile device 32 can input, via a user interface (not shown), a second instruction to display the first content C1 displayed on the screen of the first display device 11 on the screen of the second mobile device 32. Examples of the user interface include operating a switch provided on the second mobile device 32, touching a touch panel device provided on the second mobile device 32, voice input to a voice recognition function provided on the second mobile device 32, gesture input to a gesture recognition function provided on the second mobile device 32, etc.

[0023] 2, the second mobile device 32 is configured to output a second request signal RQ2 corresponding to the second instruction. The second request signal RQ2 may be an analog signal or a digital signal depending on the specifications of the second mobile device 32.

[0024] The input interface 131 is configured to be able to receive a second request signal RQ2 as well. The processor 132 is configured to output, based on the second request signal RQ2, a second display control signal DC2 for displaying the first content C1 on the screen of the second mobile device 32 from the output interface 133. This allows the display control device 13 to mirror the first content C1 displayed on the first display device 11 onto the screen of the second mobile device 32, as illustrated in FIG.

[0025] According to the above configuration, content can be shared between the driver and passengers by switching the content displayed on the screen of the first display device 11 from the first content C1 to the second content C2, or by switching the content displayed on the screen of the second mobile device 32 from the second content C2 to the first content C1. In particular, the passengers can view the first content C1 on the screen of their own second mobile device 32, closer than the first display device 11. This improves the convenience of the display control system 10, which can display content displayed on the screens of multiple mobile devices owned by multiple passengers on the common first display device 11.

[0026] 2, the display control system 10 may include a second display device 12. As illustrated in Fig. 1, the second display device 12 is installed closer to a passenger seat 23 than to a driver's seat 22 in a passenger compartment 21. The second display device 12 has a screen capable of displaying content including images.

[0027] In this case, the processor 132 of the display control device 13 is configured to output, from the output interface 133, a third display control signal DC3 that causes the second content C2 displayed on the screen of the second mobile device 32 to be displayed on the screen of the second display device 12. The third display control signal DC3 may be an analog signal or a digital signal depending on the specifications of the second display device 12.

[0028] That is, as illustrated in FIG. 7, the display control device 13 is configured to mirror the second content C2 displayed on the screen of the second mobile device 32 onto the screen of the second display device 12.

[0029] In this case, a first instruction to display the second content C2 on the screen of the first display device 11 can be input to the second display device 12. That is, the second display device 12 is also configured to be able to output a first request signal RQ1 corresponding to the first instruction.

[0030] The processor 132 outputs a first display control signal DC1, which causes the first content C1 to be displayed on the screen of the first display device 11, from the output interface 133, based on the first request signal RQ1 received by the input interface 131. As a result, the second content C2 is mirrored on the screen of the first display device 11, as illustrated in FIG.

[0031] According to this configuration, the passenger can view the second content C2 through the second display device 12, which is installed closer to the passenger seat 23 than the driver's seat 22, without taking his / her hands off the second mobile device 32. In addition, the passenger can also perform an operation to share the second content C2 with the driver. In this case, a seamless operation feeling can be provided without touching the second mobile device 32.

[0032] The second display device 12 is preferably configured to be able to accept touch operation input. In this case, as illustrated in Fig. 7, the first instruction can be given by flicking the screen of the second display device 12 in the direction of the first display device 11.

[0033] With this configuration, the second content C2 displayed on the second display device 12 can be displayed on the screen of the first display device 11, thereby making the operation of sharing the second content C2 with the driver intuitive.

[0034] Note that, if the operation can be made to have directionality toward first display device 11, the first instruction may be given by a swipe operation or a drag operation instead of a flick operation.

[0035] 2, the input interface 131 of the display control device 13 can receive speed data V indicating the travel speed of the vehicle 20. The speed data V may be input from a speed sensor mounted on the vehicle 20, or may be input from another processing device mounted on the vehicle 20 that calculates the travel speed based on various information. The speed data V may be in the form of analog data or digital data, depending on the specifications of the sensor or device that is the sender.

[0036] In this case, the processor 132 is configured to determine whether the travel speed of the vehicle 20 indicated by the speed data V exceeds a threshold. If it is determined that the travel speed exceeds the threshold, the processor 132 is configured to limit the display of the second content C2 on the screen of the first display device 11.

[0037] FIG. 9 illustrates a state in which the second content C2 displayed on the screen of the second mobile device 32 is mirrored to the screen of the first display device 11 based on the first instruction.

[0038] When it is determined that the moving speed of the vehicle 20 indicated by the speed data V received by the input interface 131 exceeds a threshold, the processor 132 outputs a first display control signal DC1 from the output interface 133 to display a mask image 40 on the screen of the first display device 11, which obstructs viewing of the second content C2, as illustrated in FIG. 10.

[0039] It should be noted that the mask image 40 does not need to be displayed on the entire screen of the first display device 11. Of the image displayed on the screen of the first display device 11, only a moving image portion with relatively large movement may be covered by the mask image 40.

[0040] FIG. 11 illustrates a state in which a first instruction to display the second content C2 on the screen of the first display device 11 is input to the second display device 12.

[0041] When it is determined that the traveling speed of the vehicle 20 indicated by the speed data V received by the input interface 131 exceeds the threshold, the processor 132 displays an error notification image 41 on the screen of the second display device 12 without changing the content displayed on the screen of the first display device 11 based on the first instruction, as illustrated in Fig. 12. This processing can be executed in addition to or instead of displaying the mask image 40 described above.

[0042] Specifically, as illustrated in FIG. 2, the processor 132 invalidates the first request signal RQ1 received from the second display device 12 by the input interface 131, and outputs a third display control signal DC3 from the output interface 133 to display an error notification image 41 on the screen of the second display device 12.

[0043] The second content C2 may be shared from the passenger to the driver by inputting a first instruction to a user interface provided by the second mobile device 32. That is, the second mobile device 32 may also be configured to output a first request signal RQ1.

[0044] In this case, when it is determined that the moving speed of the vehicle 20 indicated by the speed data V received by the input interface 131 exceeds the threshold value, the processor 132 invalidates the first request signal RQ1 received from the second mobile device 32 by the input interface 131, and outputs a second display control signal DC2 from the output interface 133 to display an error notification image 41 on the screen of the second mobile device 32.

[0045] According to the configuration described with reference to Figures 9 to 12, it is possible to prevent the second content C2 displayed on the screen of the first display device 11, which is shared by the passenger with the driver, from unintentionally interfering with the driver's driving operation of the vehicle 20.

[0046] As illustrated in Fig. 2, the vehicle 20 is equipped with a steering device 24. The steering device 24 is a device for causing the vehicle 20 to perform an operation (steering operation) to change the direction of travel. As illustrated in Figs. 2 to 4, the user interface 14 may be provided in the steering device 24.

[0047] Therefore, a first instruction requesting mirroring of the second content C2 displayed on the second mobile device 32 on the screen of the first display device 11 can be given through the steering device 24.

[0048] According to this configuration, various instructions given by the driver can be input with the minimum necessary movements. However, the location of the user interface 14 in the passenger compartment 21 can be determined appropriately.

[0049] The processor 132 of the display control device 13, which has the various functions described above, can be realized by at least one dedicated integrated circuit having a storage element in which a computer program for realizing the functions is pre-installed. Examples of the dedicated integrated circuit include a microcontroller, an ASIC, and an FPGA. The storage element is an example of a non-transitory computer-readable medium on which a computer program is stored.

[0050] The processor 132 may be realized by at least one general-purpose microprocessor operating in cooperation with at least one general-purpose memory. Examples of a general-purpose microprocessor include a CPU, an MPU, and a GPU. Examples of a general-purpose memory include a ROM and a RAM. In this case, a computer program for implementing the relevant functions may be stored in the ROM. The general-purpose memory is an example of a non-transitory computer-readable medium on which a computer program is stored. The general-purpose microprocessor specifies at least a portion of the program stored in the ROM, expands it in the RAM, and executes the above-described processing in cooperation with the RAM. The processor 132 may be realized by a combination of a dedicated integrated circuit and a general-purpose microprocessor.

[0051] The configurations referred to above are merely examples for facilitating understanding of the present disclosure. Each configuration example can be appropriately modified or combined with other configuration examples within the scope of the present disclosure.

[0052] In the above embodiment, the expression "displaying the first content displayed on the screen of the first mobile device on the screen of the first display device" describes a situation in which the first content C1 initially belongs to the first mobile device 31. However, if the first content C1 is ultimately shared between the screen of the first display device 11 and the screen of the first mobile device 31, the above expression may also describe a situation in which the first content C1 does not initially belong to the first mobile device 31. For example, the first content C1 may be stored in a storage device (not shown) mounted on the vehicle 20, or in a storage device (not shown) located on an external communication network. In this case, the first content C1 is received by the input interface 131 of the display control device 13 via an appropriate path.

[0053] 1, the vehicle 20 is equipped with a rear seat 25. In addition to or instead of being installed near the passenger seat 23, the second display device 12 may be installed in a position where the content displayed on the screen can be viewed by a passenger seated in the rear seat 25. The passenger seated in the rear seat 25 is also an example of a second passenger.

[0054] The display control system 10 can also be installed in a moving body other than the vehicle 20. Examples of such a moving body include a train, a ship, an airplane, etc. Note that the occupants of the moving body do not necessarily have to include the driver of the moving body.
