[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] FIG. 1 is a conceptual diagram showing an outline of a passenger car equipped with a sun visor type display device according to one embodiment of the display device of the present invention. FIG. 2 is a conceptual diagram showing the external appearance of the interior of a passenger car equipped with a sun visor type display device according to one embodiment of the display device of the present invention.

[0012] As shown in FIGS. 1 and 2, an automobile has a sign visor type display device 1 that functions as a sun visor when placed above the windshield. The sun visor type display device 1 includes a sun visor type display device 21 and a camera unit 22. The sun visor type display device 21 is configured as a liquid crystal display or an organic EL display that displays various images to the passengers of the automobile. The camera unit 22 is configured as a built-in camera for acquiring images that are candidates for display on the sun visor type display device 1 or images used for display control. Specifically, the camera unit 22 captures an image of the interior of the vehicle, including the vehicle occupants as subjects, and outputs the resulting captured image (hereinafter referred to as an "interior image"). As will be described in detail later, the interior image may be displayed on the sun visor-type display device 21 to be used as a mirror for the occupants, or may be used to detect the state of the occupants (for example, the movement of the occupants' eyes) etc. In the latter case, display control is performed, such as correcting or changing the image displayed on the sun visor-type display device 21, depending on the detected state of the occupants.

[0013] The automobile is also provided with a normal display device 2 that is placed on the dashboard or the like.

[0014] Furthermore, the automobile is equipped with various sensors, and signals from the various sensors are acquired, managed, and controlled by an ECU 3 (Electronic Control Unit 3). The vehicle in this embodiment will be described as an electric vehicle. For example, in the example of FIG. 1, the ECU 3 acquires a signal from a battery sensor, manages information related to the battery, and executes control. The ECU 3 acquires signals from a shift position (reference numerals omitted in FIG. 1) and a parking brake (reference numerals omitted in FIG. 1), manages information related to steering, and executes control. The ECU 3 acquires a signal from an inverter sensor, manages information related to the inverter, and executes control. The ECU 3 acquires a signal from a motor sensor, manages information related to the motor, and executes control.

[0015] 1, for ease of explanation, only one ECU 3 is shown, but generally, a plurality of ECUs 3 are provided. In this case, from a maintenance perspective, it would be costly to wire each ECU 3 and obtain the information necessary for maintenance, so a CAN (Controller Area Network) bus (hereinafter referred to as the "CAN bus") for control communication is used for connection.

[0016] In this embodiment, various types of information about the vehicle (hereinafter referred to as "in-vehicle information") acquired from the ECU 3 as needed are also provided to the sun visor type display device 1 as candidates for display items for the sun visor type display device 1.

[0017] Furthermore, in this embodiment, a front camera 4, a rear camera 5, and a side camera 6 are also provided as cameras for capturing images to be displayed on the sun visor type display device 1. The front camera 4 captures an image of the area in front of the automobile, and outputs and provides the resulting captured image (hereinafter referred to as a “front image”) to the sun visor type display device 1. The rear camera 5 captures an image of the area behind the automobile, and outputs and provides the resulting captured image (hereinafter referred to as a “rear image”) to the sun visor type display device 1. The side camera 6 captures an image of the side of the automobile, and outputs and provides the resulting captured image (hereinafter referred to as a “side image”) to the sun visor type display device 1.

[0018] When the sun visor type display device 1 is functioning as a sun visor, it can acquire various types of information from the built-in camera unit 22, ECU 3, front camera 4, rear camera 5, side camera 6, and external device 7 described below, and display various types of images on the sun visor type display device 21. This allows the visibility ahead of the vehicle to be secured while blocking direct sunlight from being irradiated through the windshield while the vehicle is moving. Specific examples of images displayed on the sun visor type display device 21 will be described later with reference to FIGS.

[0019] The configuration of the sun visor type display device 1 will be described below with reference to FIGS. FIG. 3 is a diagram showing an example of the configuration of an information processing system including the sun visor type display device of FIGS. 1 and 2, i.e., an information processing system to which a sun visor type display device according to one embodiment of the display device of the present invention is applied.

[0020] In the information processing system shown in Fig. 3, the sun visor-type display device 1 and the ECU 3 are connected to each other via a CAN bus CB so that they can communicate with each other. The sun visor-type display device 1 and an external device 7 are connected to each other via a predetermined network NW such as the Internet so that they can communicate with each other. The sun visor-type display device 1 is also connected to a front camera 4, a rear camera 5, and a side camera 6 installed in the automobile by predetermined wiring inside the automobile. 3, the normal display device 2 in FIG. 1 may also be connected to the sun visor-type display device 1 via a network NW or the like as a component of the information processing system. This allows the normal display device 2 to cooperate with the sun visor-type display device 1 to display an image that is the same as or a supplementary image to the image displayed on the sun visor-type display device 1.

[0021] The sun visor type display device 1 is an information processing device mounted on the automobile shown in Fig. 1 and equipped with a sun visor type display device 21 and a camera unit 22. The sun visor type display device 1 exchanges various information with the camera unit 22, ECU 3, front camera 4, rear camera 5, side camera 6, and external device 7, and executes control to display various images based on the various information on the sun visor type display device 21, as well as executes various processes.

[0022] The ECU 3 is an information processing device installed in the automobile, which acquires and manages information from various sensors installed in the automobile, and also executes various controls. The external device 7 is an information processing device managed by a predetermined administrator, and has a function of providing weather information, for example.

[0023] Next, the hardware configuration of the sun visor type display device 1 will be described. FIG. 4 is a block diagram showing the hardware configuration of the sun visor type display device 1 of FIG.

[0024] The sun visor type display device 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an input unit 16, an output unit 17, a memory unit 18, a communication unit 19, a drive 20, a camera unit 22, and a CAN bus control unit 23.

[0025] The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 18 into the RAM 13 . The RAM 13 also stores data and the like necessary for the CPU 11 to execute various processes.

[0026] The CPU 11, ROM 12, and RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14. An input unit 16, an output unit 17, a memory unit 18, a communication unit 19, a drive 20, a camera unit 22, and a CAN bus control unit 23 are connected to the input / output interface 15.

[0027] The input unit 16 is composed of various hardware components and is used to input various types of information. The output unit 17 is composed of various displays including a sun visor type display device 21, various speakers, etc., and outputs various information as images and sounds. The storage unit 18 is configured with a DRAM (Dynamic Random Access Memory) or the like, and stores various data. The communication unit 19 controls communication with other devices (e.g., the external device 7 in Figure 3) via a network NW including the Internet, and communication with various devices installed in the automobile (e.g., the front camera 4, rear camera 5, and side camera 6 in Figures 1 and 3).

[0028] The drive 20 is provided as needed. Removable media 31, such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory, is appropriately attached to the drive 20. Programs read from the removable media 31 by the drive 20 are installed in the storage unit 18 as needed. The removable media 31 can also store various data stored in the storage unit 18 in the same way as the storage unit 18.

[0029] As described above, the camera unit 22 is configured as an internal camera, captures images of the interior of the vehicle, and outputs the resulting images of the interior of the vehicle. The CAN bus control unit 23 executes control to exchange information with the ECU 3 via the CAN bus.

[0030] Next, the functional configuration of the sun visor type display device 1 will be described with reference to FIG. FIG. 5 is a functional block diagram showing an example of the functional configuration of the sun visor type display device of FIG.

[0031] As shown in Figure 5, the CPU 11 of the sun visor type display device 1 functions as a display control information acquisition unit 51, a front information generation unit 52, a rear information generation unit 53, a side information generation unit 54, an in-vehicle information generation unit 55, an other information generation unit 56, and a display control unit 57.

[0032] The display control information acquisition unit 51 acquires information regarding the image to be displayed on the sun visor type display device 1, or information used for display control of the sun visor type display device 1, as display information from the built-in camera unit 22, ECU 3, front camera 4, rear camera 5, side camera 6, and external device 7.

[0033] The display control unit 57 generates an image to be displayed based on the display information and controls the sun visor type display device 21 to display the image.

[0034] For example, the forward information generation unit 52 generates information (hereinafter referred to as "forward information") for generating an image showing the forward scenery that would be visible from a part of the windshield if the display area of ​​the sun visor-type display device 21 were a part of the windshield, based on at least the forward image from the forward camera 4 among the display information. When the display control unit 57 determines that the vehicle is moving based on information from the ECU 3 among the display control information (for example, information based on the shift position signal or the parking brake signal described above), it generates an image of the range blocked by the sun visor function of the sun visor type display device 1 (in the example of the same figure, an image including the top of the vehicle ahead on the left and the top of the tower) based on the forward information, as shown in Figure 6, and executes control to display it on the sun visor type display device 21. FIG. 6 is a diagram showing an example of an image displayed on a sun visor type display device having the functional configuration of FIG. If an image that is too bright (too luminance) is displayed on the sun visor-type display device 21, the purpose of the sun visor-type display device 1 fulfilling its sun visor function will be defeated. Therefore, the display control unit 57 executes control to display the image shown in Fig. 6 on the sun visor-type display device 21 while adjusting the light (adjusting the brightness to an appropriate level).

[0035] Furthermore, when the sun visor type display device 1 is not functioning as a sun visor, it needs to be folded so as not to block the windshield (see Figure 9), and part of the sun visor type display device 1 needs to be attached to the roof. Therefore, as shown in Figure 6, the area that hides the roof when the sun visor type display device 1 is performing the sun visor function can also be made the display area of ​​the sun visor type display device 21, so that an image can be displayed in that display area as well. Specifically, for example, the forward information generation unit 52 generates forward information based on at least the forward image from the forward camera 4 among the display information, in order to generate an image showing the forward view that would be visible from a part of the windshield and the transparent roof portion if it is assumed that a part of the display area of ​​the sun visor type display device 21 is a part of the windshield plus a transparent roof portion. When the display control unit 57 determines that the vehicle is moving, it executes control to display on the sun visor type display device 21, based on forward information, an image of the area blocked by the sun visor function of the sun visor type display device 1 and the area corresponding to the roof portion (an image including the top of the tower in the example of the same figure), as shown in FIG. 6. By doing this, the driver can see the scenery that is normally hidden by the roof, such as the top of the tower in the example of Figure 6, as well as traffic lights and other scenery in high positions, making it easier to drive safely.

[0036] While driving, the driver usually uses the rearview mirror to check what is happening behind the vehicle. However, when the sun visor type display device 1 is performing the sun visor function, it may cover the rearview mirror and make it impossible to use the rearview mirror. In such a case, for example, the rear information generation unit 53 generates information (hereinafter referred to as "rear information") for generating an image showing the rear view that would be visible from the rearview mirror if the area of ​​the display area of ​​the sun visor-type display device 21 that covers the rearview mirror were the rearview mirror, based on at least the rearview image from the rearview camera 5 among the display information. When the display control unit 57 determines that the vehicle is moving, it generates an image based on the rear information, including at least the scenery that would be reflected in the rearview mirror if the sun visor type display device 1 were not blocking it (in the example of the same figure, an image including vehicles behind and traffic lights behind), as shown in Figure 6, and controls the image to be displayed in the area of ​​the sun visor type display device 21 that is blocking the rearview mirror. Here, the reason why the image is not an image that "shows" the view that would be reflected in the rearview mirror if the sun visor type display device 1 were not blocking it, but an image that "at least includes" the view that would be reflected in the rearview mirror if the sun visor type display device 1 were not blocking it, is as follows: That is, although an image of the rear view area that would be reflected in the rearview mirror is normally sufficient, the display control unit 57 may, in response to an instruction from the driver or the like, execute control to display an enlarged image of a specific rear view area in the area of ​​the sun visor type display device 21 that blocks the view of the rearview mirror.

[0037] Furthermore, when the display control unit 57 determines that the vehicle is backing up based on information from the ECU 3 among the display control information (for example, information based on the shift position signal (back signal) described above), it generates an image showing the rear of the vehicle, as shown in Figure 7, based on the rear information, and executes control to display the image fully on the sun visor-type display device 21. FIG. 7 is a diagram showing an example of an image displayed on a sun visor type display device having the functional configuration of FIG. 5, which is different from FIG.

[0038] Furthermore, although not shown in the figure, the display control unit 57 may execute control to display an image of the BSM (an image including text information and image information of the BSM) in a predetermined area of ​​the sun visor-type display device 21 when the vehicle is moving forward, for example, at 15 km / h or more, based on information from the ECU 3 among the display control information. In such a case, for example, the side information generating unit 54 generates information for generating an image of the BSM (hereinafter referred to as "side information") based on at least the side image from the side camera 6 among the display information. The display control unit 57 may execute control to generate an image of the BSM based on the side information (and further rear information as necessary) and display it in a predetermined area of ​​the sun visor type display device 21.

[0039] Furthermore, when the display control unit 57 determines that the vehicle is stopped based on the information from the ECU 3 among the display control information, it generates a mirror image (an image showing the interior of the vehicle) as shown in Figure 8 based on the interior image from the built-in camera unit 22 and executes control to display it fully on the sun visor-type display device 21. FIG. 8 is a diagram showing an example of an image displayed on a sun visor type display device having the functional configuration of FIG. 5, which is different from the examples shown in FIGS. In such a case, for example, the in-vehicle information generation unit 55 generates information (hereinafter referred to as "in-vehicle information") for generating a mirror image showing the state inside the vehicle based on at least the in-vehicle image from the built-in camera unit 22 among the display information. The display control unit 57 may execute control to generate a mirror image based on the in-vehicle information and display it on the sun visor type display device 21.

[0040] The image displayed on the sun visor type display device 21 while the car is stopped is not particularly limited to the mirror image shown in FIG. 8, and any image can be used. For example, the sun visor type display device 21 may function as an external display.

[0041] For example, although not shown, when the display control unit 57 determines that the vehicle is stopped, it generates images (hereinafter referred to as "other images") showing various information such as vehicle information based on information from the ECU 3 and the external device 7, and controls the display of these images on the sun visor-type display device 21. In such a case, for example, the other information generating unit 56 generates information for generating other images (hereinafter referred to as "other information") based on information from the ECU 3 or the external device 7. The display control unit 57 may execute control to generate another image based on the other information and display it on the sun visor type display device 21. For example, the sun visor-type display device 1 of this embodiment can use CAN information as other information to predict that the battery temperature of an electric vehicle will rise and become unable to drive if the situation continues, and generate an other image showing the prediction result to present to the user.The sun visor-type display device 1 can also use external information from the external device 7 as other information to generate an other image containing advice on a more appropriate countermeasure, and present this to the user.For example, when the outside temperature is high and the weather is clear based on the external information, the sun visor-type display device 1 can provide the user with an other image containing advice on a countermeasure such as parking in the shade.

[0042] FIG. 9 is an image diagram showing the interior of a car with the sun visor type display device of FIG. 2 folded up. When the sun visor type display device 1 does not need to function as a sun visor, it is folded as shown in FIG. 9, so that the entire windshield becomes the visible range and the rearview mirror BM for checking the rear can also be used. Although not shown in the figure, a sun visor type display device 21 may also be placed in the area of ​​the sun visor type display device 1 that is visible to passengers inside the vehicle when it is folded, to display a front image of the roof portion and information on the rear BSM while the vehicle is moving, or to display a mirror image and various other images while the vehicle is stopped.

[0043] Although the preferred embodiments of the display device of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate.

[0044] For example, the hardware configuration shown in FIG. 4 is merely an example for achieving the object of the present invention, and is not particularly limited.

[0045] Furthermore, the functional block diagram shown in Fig. 5 is merely an example and is not particularly limited. That is, it is sufficient for the information processing system to be provided with a function that can execute the above-described series of processes as a whole, and the type of functional block used to realize this function is not particularly limited to the example of Fig. 5.

[0046] Furthermore, the locations of the functional blocks are not limited to those shown in Fig. 5 and may be arbitrary. For example, at least some of the functional blocks on the in-vehicle display device 1 side may be provided in another device (not shown), or vice versa. A single functional block may be configured by a single piece of hardware, or may be configured in combination with a single piece of software.

[0047] When the processing of each functional block is performed by software, the program that constitutes the software is installed into a computer or the like from a network or a recording medium. The computer may be a computer built into dedicated hardware, or may be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.

[0048] The recording medium containing such a program may not only be composed of removable media that is distributed separately from the device itself in order to provide the program to each user, but may also be composed of recording media that are provided to each user in a state where they are pre-installed in the device itself.

[0049] In this specification, the steps describing the program to be recorded on the recording medium include not only processes that are performed in chronological order, but also processes that are not necessarily performed in chronological order but are performed in parallel or individually. In addition, in this specification, the term "system" refers to an overall device that is made up of a plurality of devices, a plurality of means, etc.

[0050] In summary, the display device to which the present invention is applied is sufficient if it has the following configuration, and can take on a variety of different embodiments. That is, a display device to which the present invention is applied (for example, the sun visor type display device 1 shown in FIGS. 1 to 5) has the following features: A display device that functions as a sun visor by being disposed above the windshield of an automobile (for example, as shown in FIG. 2), and that has a predetermined display device (for example, the sun visor-type display device 21 shown in FIGS. 1 to 5) that displays an image visible to an occupant of the automobile when the sun visor function is being used, a display information acquisition unit (e.g., a display control information acquisition unit 51 in FIG. 5 ) that acquires, as display information, information about an image to be displayed on the predetermined display device or information used for display control of the predetermined display device from one or more devices (e.g., the built-in camera unit 22, ECU 3, front camera 4, rear camera 5, side camera 6, and external device 7 in FIGS. 1 , 3 , and 5 ); a display control means (for example, the display control unit 57 in FIG. 5) that generates an image of the display object based on the display information and controls the image to be displayed on the predetermined display device; It is enough to have this.
