Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a vehicle HMI, icons indicating the content of the content available in the vehicle are displayed. However, since the passengers in the vehicle are not always the same passengers every time, it cannot be generally said that the icons indicating the content of the content should be displayed based on the usage pattern of the passengers' icons as in Patent Document 1. Therefore, there is room for improvement in the appropriate display of the icons indicating the content of the content. The present invention has been made in view of the above circumstances, and an object thereof is to be able to appropriately display an icon indicating the content of the content according to the passengers in the vehicle.

Means for Solving the Problems

[0005] One aspect of the present invention is a vehicle display device comprising: a display control unit that displays icons indicating the content of content available in the vehicle using a display unit provided in the vehicle; an occupant detection unit that detects occupants of the vehicle; and a storage unit that stores occupant information relating to the occupants of the vehicle, wherein the display control unit acquires occupant information corresponding to occupants detected by the occupant detection unit from the storage unit, and displays the icons based on the acquired occupant information and content information relating to the content. [Effects of the Invention]

[0006] According to one aspect of the present invention, icons indicating the content can be appropriately displayed according to the occupants of the vehicle. [Brief explanation of the drawing]

[0007] [Figure 1] Figure 1 shows the configuration of the content output system. [Figure 2] Figure 2 shows the configuration of the vehicle display device. [Figure 3] Figure 3 shows an example of a selection screen. [Figure 4] Figure 4 is a flowchart showing the operation of the vehicle display device. [Figure 5] Figure 5 shows the configuration of the content output system. [Figure 6] Figure 6 is a diagram showing the configuration of a vehicle display device. [Modes for carrying out the invention]

[0008] [1. First Embodiment] First, the first embodiment will be described with reference to the drawings. [1-1. Content Output System Configuration] Figure 1 is a diagram showing the configuration of the content output system 1000 according to the first embodiment. The content output system 1000 is a system that outputs content within vehicle 1. Examples of content output by the content output system 1000 include movies, still images, and music. Furthermore, the content output by the content output system 1000 is content that can be used within vehicle 1. In addition, content that can be used within vehicle 1 includes content distributed by content distributors contracted by occupant P.

[0009] As shown in Figure 1, the content output system 1000 comprises a vehicle 1, a content distribution server 2, and an icon distribution server 3. Before describing Vehicle 1, let's explain Content Distribution Server 2 and Icon Distribution Server 3.

[0010] Content distribution server 2 is a server device that distributes content. Content distribution server 2 is connected to a network NW and communicates with vehicle 1. The network NW is a communication network consisting of a public telephone network, a dedicated line, or other communication circuits. The content output system 1000 may have a content distribution server 2 for each content distribution source. Alternatively, content distribution server 2 may be a server device that aggregates content distributed by multiple content distribution sources and distributes it to vehicle 1.

[0011] Icon distribution server 3 is a server device that distributes image data of icon ICs that represent the content using pictures, photographs, text, symbols, etc. Icon distribution server 3 is connected to a network NW and communicates with vehicle 1. Icon distribution server 3 stores multiple sets of content IDs (Identification) that identify the content and content information associated with the content, and transmits content information corresponding to the content ID sent from vehicle 1 to vehicle 1. The content information includes image data of one or more icon ICs. In addition, one piece of content information is associated with the image data of one icon IC. The content information indicates the content shown by the corresponding icon IC. Specifically, the content information indicates the name of the person depicted on the icon IC and appearing in the content, the facial expression of that person, the genre of the content, the name of the composer or lyricist of the content, and the type of picture or photograph depicted on the icon IC (e.g., violent).

[0012] The genres of content include, for example, action films, adventure films, animated films, documentaries, and horror films. For music, genres include rock, reggae, phonk, and trance. For video, genres include streaming, product reviews, entertainment, and readings. For still images, genres include Western paintings and Eastern paintings.

[0013] The vehicle 1 illustrated in Figure 1 is a four-wheeled vehicle. Vehicle 1 is equipped with a driver's seat 10A, a passenger seat 10B, a rear right seat 10C, and a rear left seat 10D. In Figure 1, occupant P1, who is the driver, is seated in the driver's seat 10A. In Figure 1, occupant P2, who is a passenger, is seated in the passenger seat 10B. In Figure 1, occupant P3, who is a passenger, is seated in the rear right seat 10C. In Figure 1, occupant P4, who is a passenger, is seated in the rear left seat 10D.

[0014] Vehicle 1 includes a right front door 11A, a left front door 11B, a right rear door 11C, a left rear door 11D, and a tailgate 11E.

The tailgate 11E opens and closes the trunk of Vehicle 1.

[0015] Vehicle 1 includes a dashboard 12. The dashboard 12 has a touch panel 13 and a speaker 14 installed thereon. The touch panel 13 is configured by superimposing or integrating a display panel that displays characters and images and a touch sensor that detects contact with the display panel. The speaker 14 outputs sound into the passenger compartment space of Vehicle 1. The installation position and number of the speaker 14 can be arbitrarily changed. The touch panel 13 is an example of a "display unit".

[0016] A camera 15 for photographing the interior of Vehicle 1 is installed inside the passenger compartment of Vehicle 1. The photographing range of the camera 15 is set to a range capable of photographing the occupant P sitting in the driver's seat 10A and the occupant P sitting in the passenger seat 10B. More specifically, the photographing range of the camera 15 is set to a range capable of photographing the heads (including the faces) of these two occupants P.

[0017] Vehicle 1 includes a shift lever 16 installed near the driver's seat 10A.

[0018] A camera 17 is installed inside the passenger compartment of Vehicle 1. The camera 17 is installed, for example, on the back of the driver's seat 10A and photographs the occupant P sitting in the right rear seat 10C. The photographing range of the camera 17 is set to a range capable of photographing the occupant P sitting in the right rear seat 10C. More specifically, the photographing range of the camera 17 is set to a range capable of photographing the head (including the face) of the occupant P sitting in the right rear seat 10C.

[0019] A camera 18 is installed inside the vehicle 1. For example, the camera 18 is installed on the back of the passenger seat 10B and photographs occupant P seated in the rear left seat 10D. The shooting range of the camera 18 is set to be able to photograph occupant P seated in the rear left seat 10D. More specifically, the shooting range of the camera 18 is set to be able to photograph the head (including face) of occupant P seated in the rear left seat 10D.

[0020] Vehicle 1 is equipped with a vehicle display device 19. The vehicle display device 19 outputs content distributed by the content distribution server 2, content stored in the mobile terminal 4, and content received by the mobile terminal 4, via at least one of the touch panel 13 and the speaker 14. The vehicle display device 19 displays various information via the touch panel 13. In this embodiment, the vehicle display device 19 displays a selection screen G for selecting content that can be output.

[0021] Vehicle 1 is equipped with a communication device 20. The communication device 20 is equipped with hardware that conforms to a predetermined communication standard, such as a wireless communication circuit, and communicates with a content distribution server 2 and an icon distribution server 3 that are connected to a network NW.

[0022] Vehicle 1 is equipped with a communication device 21. The communication device 21 is equipped with hardware that conforms to a predetermined communication standard, such as a communication circuit, and communicates with the mobile terminal 4. The communication standard of the communication device 21 may be either a wired communication standard or a wireless communication standard.

[0023] [1-2. Configuration of the vehicle display device] Next, referring to Figure 2, this is a diagram showing the configuration of the vehicle display device 19. Figure 2 shows the configuration of the vehicle display device 19.

[0024] The vehicle display device 19 is connected to a touch panel 13, a speaker 14, cameras 15, 17, and 18, a communication device 20, a communication device 21, and a shift position sensor 22. Note that the devices connected to the vehicle display device 19 are not limited to these devices, and other types of devices may also be connected.

[0025] The touch panel 13 displays various information in accordance with the control of the vehicle display device 19. The speaker 14 outputs various sounds according to the control of the vehicle display device 19. Cameras 15, 17, and 18 take pictures at predetermined intervals and output the captured images to the vehicle display device 19. The communication device 20 communicates with the vehicle display device 19, the content distribution server 2, and the icon distribution server 3. The communication device 21 communicates with the vehicle display device 19 and the mobile terminal 4. The shift position sensor 22 detects the shift position of the shift lever 16 provided by the vehicle 1. The shift positions include, for example, P (parking) used when parked, R (reverse) and N (neutral) used when reversing, and D (drive) used when driving.

[0026] The vehicle display device 19 includes a processor 100 such as a CPU (Central Processing Unit) or MPU (Micro Processor Unit), a memory 110, and an interface circuit for connecting other devices and sensors. Memory 110 is an example of a "storage unit".

[0027] Memory 110 is a storage device that stores programs and data. Memory 110 stores the first APP 111, the second APP 112, the third APP 113, the control program 114, the crew database 115, and data to be processed by the processor 100. Memory 110 has a non-volatile storage area. Alternatively, memory 110 may also have a volatile storage area and constitute the work area of ​​the processor 100. Memory 110 is composed of, for example, ROM (Read Only Memory) or RAM (Random Access Memory). Control program 114 is an example of a "program".

[0028] App 111 is an application program for using content distributed by a single content provider. APP112 is an application program for using content distributed by a different content provider than APP111. The third app, APP113, is an application program for using content distributed by a different content provider than the first app, APP111, and the second app, APP112.

[0029] The control program 114 is a program that causes the processor 100 to function as a functional unit, which will be described later.

[0030] Crew DB115 is a database containing one crew information entry R1 for each crew member P. Each crew information entry R1 includes facial feature information J1 and one or more preference information J2. This crew information R1 is created in advance and registered in Crew DB115.

[0031] Facial feature information J1 represents the facial features of crew member P. Facial features are comprised of multiple items, such as the position of the eye feature points, the position of the nose feature points, the position of the mouth feature points, and the size of the face region.

[0032] Preference information J2 is information that indicates the object of a person's preference regarding content. Each piece of preference information J2 indicates only one object of preference. Preference information J2 records information such as the genre of content preferred, and the names of people such as actors, actresses, singers, musicians, composers, and lyricists that the person prefers. Note that in Figure 2, honorifics are included as an example of the person's name, but the name of the person indicated by preference information J2 does not necessarily have to include honorifics.

[0033] The processor 100 functions as the first content output unit 101 by reading and executing the first APP 111 stored in the memory 110. The first content output unit 101 receives content from the content distribution server 2 via the communication device 20, which corresponds to the first APP 111, and outputs the received content through at least one of the touch panel 13 and the speaker 14.

[0034] The processor 100 functions as a second content output unit 102 by reading and executing the second APP 112 stored in the memory 110. The second content output unit 102 receives content from the content distribution server 2 via the communication device 20, which corresponds to the content distribution source for the second APP 112, and outputs the received content through at least one of the touch panel 13 and the speaker 14.

[0035] The processor 100 functions as a third content output unit 103 by reading and executing the third APP 113 stored in the memory 110. The third content output unit 103 receives content from the content distribution server 2 via the communication device 20, which corresponds to the third APP 113, and outputs the received content through at least one of the touch panel 13 and the speaker 14.

[0036] Prior to displaying the selection screen G, the first to third content output units 101 receive content information for each available content. The content information received by the first to third content output units 103 includes image data of one or more icon ICs. In addition, content information is associated with each image data of an icon IC within this content information.

[0037] The processor 100 functions as a fourth content output unit 104, an occupant detection unit 106, a driving state detection unit 107, and a display control unit 108 by reading and executing a control program 114 stored in the memory 110.

[0038] [1-3. Fourth Content Output Section] The fourth content output unit 104 outputs at least one of the content stored by the mobile terminal 4 and the content received by the mobile terminal 4 via at least one of the touch panel 13 and the speaker 14.

[0039] The fourth content output unit 104 receives content from the mobile terminal 4 via the communication device 21 and outputs the received content. For each piece of content that can be received from the mobile terminal 4, the fourth content output unit 104 receives a content ID (Identification) from the mobile terminal 4 via the communication device 21.

[0040] When the fourth content output unit 104 receives a content ID from the mobile terminal 4, it transmits the received content ID to the icon distribution server 3 via the communication device 20. The fourth content output unit 104 then receives content information from the icon distribution server 3 for each transmitted content ID.

[0041] Hereafter, when the first content output unit 101 to the fourth content output unit 104 are not distinguished, they will be referred to as "content output unit 105" with the designation "105".

[0042] [1-4. Configuration of the Crew Detection Unit] The occupant detection unit 106 detects the occupant P of the vehicle 1. In this embodiment, the occupant detection unit 106 detects occupants P based on the captured images received from cameras 15, 17, and 18. For each received captured image, the occupant detection unit 106 detects a face image using a method such as pattern matching. The occupant detection unit 106 detects occupants P by detecting the face image.

[0043] The crew detection unit 106 calculates facial features for each detected crew member P if it has detected a face image, i.e., if it has detected a crew member P. The facial features are calculated based on, for example, the size of the face image in the captured image, the position of the eye feature points, the position of the nose feature points, the position of the mouth feature points, etc.

[0044] When the occupant detection unit 106 detects an occupant P in the vehicle 1, it detects the seating position of each detected occupant P. For example, if the occupant detection unit 106 detects a face image to the left of the center in the image captured by the camera 15, it detects the seat position of occupant P corresponding to that face image as the driver's seat 10A. Furthermore, for example, if the occupant detection unit 106 detects a face image to the right of the center in the image captured by the camera 15, it detects the seat position of occupant P corresponding to that face image as the passenger seat 10B. Furthermore, for example, if the occupant detection unit 106 detects a face image from the image captured by the camera 17, it detects the seat position of occupant P corresponding to that face image as the rear right seat 10C. Furthermore, for example, if the occupant detection unit 106 detects a face image from the image captured by the camera 18, it detects the seat position of occupant P corresponding to that face image as the rear left seat 10D.

[0045] [1-5. Configuration of the driving state detection unit] The driving state detection unit 107 detects the driving state of vehicle 1. The driving state detection unit 107 detects whether vehicle 1 is in a manual driving state. A manual driving state is a state in which an occupant P seated in the driver's seat 10A is driving the vehicle manually. For example, the driving state detection unit 107 detects that vehicle 1 is in a manual driving state when the shift position sensor 22 detects R (reverse), N (neutral), or D (drive). Also, for example, the driving state detection unit 107 detects that vehicle 1 is not in a manual driving state when the shift position sensor 22 detects P (parking). Note that "vehicle 1 is not in a manual driving state" may also include the state of vehicle 1 being in an automatic driving state. An automatic driving state means that vehicle 1 is driving even though an occupant P seated in the driver's seat 10A is not driving it manually.

[0046] [1-6. Configuration of the display control unit] The display control unit 108 displays the selection screen G via the touch panel 13. As will be described in detail later, the selection screen G displays one icon IC for each piece of content. One piece of content refers to, for example, one song, one movie, one video, or one still image.

[0047] Figure 3 shows an example of the selection screen G. In Figure 3, the upward direction is indicated by the symbol UP, the downward direction by the symbol DW, the leftward direction by the symbol L, and the rightward direction by the symbol R. These four directions—up, down, left, and right—correspond to the four directions in the state of crew member P when viewing the selection screen G.

[0048] The selection screen G includes content-related information J3 for each content provider. Content-related information J3 includes name information J31 and the list display area A1. The content provider includes content distribution destinations and mobile devices 4, etc.

[0049] Name information J31 indicates the name of the content provider. List display area A1 is an area that displays a list of content supplied by the content provider indicated by name information J31, and displays one icon IC for each piece of content.

[0050] The list display area A1 shown in Figure 3 is configured to display multiple icon ICs horizontally in a single row, but the list display area A1 may also be configured to display multiple icon ICs horizontally in multiple rows. Furthermore, the list display area A1 may be configured to display other icon ICs that were hidden before a predetermined touch operation (such as a flick or slide operation) is performed within the list display area A1.

[0051] Note that the selection screen G shown in Figure 3 is configured to allow selection of content from four content providers on a single screen. However, the screen configuration of selection screen G is not limited to the configuration shown in Figure 3. For example, selection screen G may consist of multiple screens, and one or more content providers' content may be selected on a single screen. In this example, if a predetermined touch operation (flick operation or slide operation) is performed in an area other than the list display area A1 on selection screen G, selection screen G will switch the screen displaying the content to a screen displaying content from another content provider.

[0052] The icon IC displayed in the list display area A1 differs depending on whether or not the memory 110 has stored crew information R1 for all crew members P detected by the crew detection unit 106. If the memory 110 does not store crew information R1 for all crew members P detected by the crew detection unit 106, the icon IC displayed in the list display area A1 is an icon IC that is not based on crew information R1. On the other hand, if the memory 110 stores the crew information R1 of all crew members P detected by the crew detection unit 106, the icon IC displayed in the list display area A1 is the icon IC based on the crew information R1 of crew member P detected by the crew detection unit 1066.

[0053] Hereinafter, the selection screen G in which an icon IC is displayed that is not based on crew information R1 will be referred to as the "first selection screen," and the selection screen G in which an icon IC is displayed that is based on crew information R1 will be referred to as the "second selection screen."

[0054] [1-6-1. First Selection Screen] The first selection screen will be described in detail. On the first selection screen, in the list display area A1, icons IC not based on crew information R1 are displayed. Icons IC not based on crew information R1 refer to icons IC selected from the icons IC included in the content information, without considering the preference information J2 included in crew information R1.

[0055] Here, we will explain the process related to the display of the first selection screen of the display control unit 108. The display control unit 108 determines whether or not the crew information R1 corresponding to each crew member P detected by the crew member detection unit 106 is stored in the memory 110. More specifically, in this embodiment, the display control unit 107 acquires facial features from the occupant detection unit 106 for each occupant P, and determines for each occupant P whether or not there is occupant information R1 that includes facial features with a matching rate equal to or greater than a threshold. If the display control unit 107 determines that such occupant information R1 exists, it determines that occupant information R1 corresponding to occupant P is stored, and if it determines that such occupant information R1 does not exist, it determines that occupant information R1 corresponding to occupant P is not stored.

[0056] Then, if the display control unit 107 detects any crew member P among those detected by the crew member detection unit 106, and the memory 110 does not store crew member information R1 for that crew member P, it displays the first selection screen via the touch panel 13.

[0057] When displaying the first selection screen, the display control unit 107 performs the following processing for each content supplier. In other words, the display control unit 107 selects multiple pieces of content information that the content provider can supply. The selection is made randomly. Next, the display control unit 107 obtains an icon IC from each of the selected pieces of content information. The acquisition of the icon IC may be random, or it may be done by referring to the content information and obtaining an icon IC other than a predetermined depiction (for example, a violent depiction). Then, the display control unit 107 generates content-related information J3, which includes a list display area A1 in which the acquired icon ICs are arranged and name information J31, and includes the generated content-related information J3 in the first selection screen.

[0058] [1-6-2. Second Selection Screen] The second selection screen will be described in detail. On the second selection screen, the icon IC based on crew information R1 is displayed in the list display area A1. The icon IC based on crew information R1 refers to the icon IC selected from the content information, taking into account the preference information J2 contained in the crew information R1.

[0059] If the crew detection unit 106 detects only one crew member P, the following icon IC will be displayed in the list display area A1 of the second selection screen. In other words, in the list display area A1 of the second selection screen, for each piece of content, an icon IC is displayed based on the preference information J2 contained in the detected crew information R1 of crew member P.

[0060] For example, suppose the detected crew member P's crew member information R1 includes preference information J2 indicating "DDD" as the actor's name, preference information J2 indicating "horror movies" as the content genre, and preference information J2 indicating "EEE" as the actress's name. In this example, in the list display area A1 that shows movie content, for some content, an icon IC representing the actor "DDD" is displayed; for other content different from the first, an icon IC representing a person with a frightened expression is displayed; and for yet another piece of content, an icon IC representing the actress "EEE" is displayed.

[0061] If the crew detection unit 106 detects multiple crew members P, the following icons IC will be displayed in the list display area A1 of the second selection screen. In other words, in the list display area A1 of the second selection screen, if there are multiple matching preferences among the crew members P detected by the crew detection unit 106, an icon IC is displayed based on the preference information J2 that indicates the preference with the largest number of matches for a given content item. If there are no matching preferences among the crew members P detected by the crew detection unit 106, the same icon IC is displayed as when only one crew member P is detected by the crew detection unit 106.

[0062] For example, suppose crew members P1, P2, P3, and P4 are detected. In this example, crew member P1's crew information R1 includes preference information J2 indicating "DDD" as the actor's name and preference information J2 indicating "horror movies" as the content genre. In this example, crew member P2's crew information R1 includes preference information J2 indicating "DDD" as the actor's name and preference information J2 indicating "action movies" as the content genre. In this example, crew member P3's crew information R1 includes preference information J2 indicating "DDD" as the actor's name and preference information J2 indicating "adventure movies" as the content genre. In this example, crew member P4's crew information R1 includes preference information J2 indicating "EEE" as the actor's name. In this example, among crew members P1, P2, P3, and P4, the object of preference with the highest number of matching votes is the name "DDD-san". Therefore, in this example, the list display area A1 for displaying movie content will display an icon IC representing the actor named "DDD".

[0063] Furthermore, if the crew detection unit 106 detects multiple crew members P, the following icons IC will be displayed in the list display area A1 of the second selection screen. In other words, a priority is set for displaying the icon IC for each crew member R1, and in the list display area A1 of the second selection screen, the icon IC is displayed based on the priority set for each crew member R1. The priority is set based on the seat position of occupant P detected by the occupant detection unit 106 and the driving state of vehicle 1 detected by the driving state detection unit 107.

[0064] If vehicle 1 is not in manual driving mode, the priority is set as follows: The priority for occupant P in the driver's seat 10A is set higher than the priority for occupant P in seats other than the driver's seat 10A.

[0065] If the vehicle 1 is not in manual driving mode, the icon IC based on the occupant information R1 of occupant P in the driver's seat 10A will be displayed in the list display area A1 of the second selection screen with priority over the icon IC based on the occupant information R1 of occupants P other than those in the driver's seat 10A. Furthermore, in the list display area A1 of the second selection screen, if there are multiple occupants P other than those in the driver's seat 10A, and there are matching preferences among the occupants P other than those in the driver's seat 10A, the icon IC for the occupants P other than those in the driver's seat 10A will be displayed based on the number of matching preferences mentioned above.

[0066] In this embodiment, "prioritizing display" means displaying the icon on the left side of the selection screen G. Furthermore, if there is a hidden icon IC in the list display area A1, "prioritizing display" means displaying it on the left side of the selection screen G, and displaying it in a way that minimizes the amount of touch operation required to display it in the list display area A1.

[0067] For example, suppose occupants P1, P2, and P3 are detected. In this example, occupant information R1 of occupant P1 includes preference information J2 indicating "DDD" as the actor's name. In this example, occupant information R1 of occupant P2 includes preference information J2 indicating "EEE" as the actor's name and preference information J2 indicating "action movies" as the content genre. In this example, occupant information R1 of occupant P3 includes preference information J2 indicating "EEE" as the actor's name and preference information J2 indicating "horror movies" as the content genre. In this example, assume that vehicle 1 is not in manual driving mode.

[0068] In this example, in the list display area A1 of the second selection screen related to movie content, the icon IC representing the actor named "DDD," which crew member P1 prefers, is displayed preferentially. Also in this example, in the list display area A1 of the second selection screen related to movie content, the icon IC representing the actor named "EEE," which both crew members P2 and P3 prefer, is displayed preferentially after the icon IC representing the actor named "DDD." Note that the icon IC representing the actor named "DDD" and the icon IC representing the actor named "EEE" are different content.

[0069] When vehicle 1 is in manual driving mode, the priority is set as follows: The priority for occupant P in the driver's seat 10A is set lower than the priority for occupant P in seats other than the driver's seat 10A.

[0070] In this case, in each list display area A1 of the second selection screen, the icon IC based on the occupant information R1 of occupants P other than the driver's seat 10A will be displayed with priority over the icon IC based on the occupant information R1 of occupant P of the driver's seat 10A. Furthermore, in the list display area A1 of the second selection screen, if there are multiple occupants P other than the driver's seat 10A, and there are matching preferences among the occupants P other than the driver's seat 10A, the icon IC for the occupants P other than the driver's seat 10A will be displayed based on the number of matching preferences mentioned above.

[0071] For example, suppose occupants P1, P2, and P3 are detected. In this example, occupant information R1 of occupant P1 includes preference information J2 indicating "DDD-san" as the actor's name. In this example, occupant information R1 of occupant P2 includes preference information J2 indicating "EEE-san" as the actor's name and preference information J2 indicating "horror movies" as the content genre. In this example, occupant information R1 of occupant P3 includes preference information J2 indicating "DDD-san" as the actor's name and preference information J2 indicating "horror movies" as the content genre. In this example, assume that vehicle 1 is in manual driving mode.

[0072] In this example, the shared preference between crew members P2 and P3 is the genre "horror movies." Therefore, in the list display area A1 of the second selection screen, the icon IC representing a person with a frightened expression is displayed with priority over the icon IC based on crew member P1's crew member information R1.

[0073] Here, we will explain the process related to the display of the second selection screen of the display control unit 108. As described above, the display control unit 108 determines whether or not the crew information R1 corresponding to each crew member P detected by the crew detection unit 106 is stored in the memory 110. Next, if the memory 110 has stored the crew information R1 for all crew members P detected by the crew detection unit 106, the display control unit 108 displays the second selection screen on the touch panel 13.

[0074] When displaying the second selection screen, the display control unit 108 sets a priority for each occupant information R1 of occupant P detected by the occupant detection unit 106, based on the seat position of occupant P detected by the occupant detection unit 106 and the driving state of vehicle 1 detected by the driving state detection unit 107.

[0075] Next, the display control unit 108 sets the priority and then executes the following process for each content source. In other words, the display control unit 108 reads preference information J2 from the occupant information R1. Then, based on the preference information J2 of the occupants P other than the driver's seat 10A, the display control unit 108 identifies the objects of matching preferences among the occupants P other than the driver's seat 10A. Next, if the display control unit 108 can identify a matching preference target, it refers to the content information of each content information received by the content output unit 105 and reads out the icon IC that indicates the content of the content corresponding to the preference information J2 of the occupant P in the driver's seat 10A, and the icon IC that indicates the content of the content corresponding to the preference information J2 that indicates the identified preference target. On the other hand, if the display control unit 108 cannot identify a matching preference target, it refers to the content information of each content information received by the content output unit 105 and reads out an icon IC that indicates the content of the content corresponding to the preference information J2 of each crew member P. Next, the display control unit 108 generates content-related information J3, which includes a list display area A1 in which icons IC are arranged based on the priority set for the crew information R1, and name information J31, and includes the generated content-related information J3 in the second selection screen.

[0076] Furthermore, the icon IC that indicates the content of the content corresponding to preference information J2 is, for example, if preference information J2 indicates the name "DDD," then the icon IC is associated with content information indicating the name "DDD." Also, for example, if preference information J2 indicates the genre "horror movies," then the icon IC is associated with content information indicating the genre "horror movies" and content information indicating a person's facial expression "fear." Also, for example, if preference information J2 indicates "action movies," then the icon IC that indicates the content of the content corresponding to preference information J2 is an icon IC showing a person performing physical activity.

[0077] [1-7. Operation of the vehicle display device] Next, with reference to Figure 4, the operation of the vehicle display device 19 related to the display of the icon IC will be explained. Figure 4 is a flowchart showing the operation of the vehicle display device 19.

[0078] The display control unit 108 determines whether or not to display the selection screen G (step SA1). For example, if crew member P inputs an instruction to display a list of content on the touch panel 13, the display control unit 108 makes a positive determination in step SA1.

[0079] If the display control unit 108 determines that it will not display the selection screen G (step SA1: NO), it performs the determination in step SA1 again.

[0080] On the other hand, if the display control unit 108 determines to display the selection screen G (step SA1: YES), the occupant detection unit 106 detects an occupant P who is in the vehicle 1 (step SA2).

[0081] Next, the driving state detection unit 107 detects the driving state of the vehicle 1 (step SA3). Note that the processing order of steps SA2 and SA3 may be reversed. Also, steps SA2 and SA3 may be executed simultaneously.

[0082] Next, the display control unit 108 determines whether the memory 110 has stored the preference information J2 for all occupants P detected in step SA2 (step SA4).

[0083] If the display control unit 107 determines that the memory 110 does not store the preference information J2 for all occupants P detected in step SA2 (step SA4: NO), it displays the first selection screen via the touch panel 13 (step SA5).

[0084] Furthermore, when an icon IC is selected by touch operation on the first selection screen, the content output unit 105 outputs the content corresponding to the selected icon IC. Specifically, if the content corresponding to the selected icon IC is content distributed by the first APP 111, the first content output unit 101 receives and outputs the content corresponding to the selected icon IC. If the content corresponding to the selected icon IC is content distributed by the second APP 112, the second content output unit 102 receives and outputs the content corresponding to the selected icon IC. If the content corresponding to the selected icon IC is content distributed by the third APP 113, the third content output unit 103 receives and outputs the content corresponding to the selected icon IC. Furthermore, if the content corresponding to the selected icon IC is content that can be received from the mobile terminal 4, the fourth content output unit 104 receives and outputs the content corresponding to the selected icon IC.

[0085] On the other hand, if the display control unit 107 determines that the memory 110 has stored the preference information J2 for all occupants P detected in step SA2 (step SA4: YES), it displays the second selection screen via the touch panel 13 (step SA6).

[0086] Furthermore, in the second selection screen, when one icon IC is selected by touch operation, the content output unit 105 outputs the content corresponding to the selected icon IC, similar to the first selection screen.

[0087] [2. Second Embodiment] Next, a second embodiment will be described. In the description of the second embodiment, components that are the same as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions are omitted as appropriate.

[0088] Figure 5 shows the configuration of the content output system 1000 according to the second embodiment. As is clear from comparing Figure 5 with Figure 1, the vehicle 1 of the second embodiment is equipped with touch panels 22, 23, and 24. Furthermore, as is clear from comparing Figure 5 and Figure 1, the vehicle 1 of the second embodiment is equipped with speakers 25, 26, 27, and 28. Touch panels 22, 23, and 24 are examples of "display units".

[0089] Each of the touch panels 22, 23, and 24 consists of a display panel for displaying characters and images, and a touch sensor for detecting contact with the display panel, superimposed or integrated. Touch panel 22 is installed on the dashboard 12, on the passenger seat 10B side of touch panel 13. Touch panel 23 is installed in a position visible to occupant P seated in the rear right seat 10C, for example, on the back of the driver's seat 10A. Touch panel 24 is installed in a position visible to occupant P seated in the rear left seat 10D, for example, on the back of the passenger seat 10B.

[0090] Speaker 25 outputs sound to occupant P seated in the driver's seat 10A. Speaker 26 outputs sound to occupant P seated in the passenger seat 10B. Speaker 27 outputs sound to occupant P seated in the rear right seat 10C. Speaker 28 outputs sound to occupant P seated in the rear left seat 10D. Note that the installation positions of speakers 25, 26, 27, and 28 are not limited to those shown in Figure 5, but are acceptable as long as they can output sound to occupant P seated in the corresponding seats.

[0091] Figure 6 shows the configuration of the vehicle display device 19 according to the second embodiment. As is clear from comparing Figure 6 and Figure 2, the vehicle display device 19 is connected to touch panels 22, 23, and 24, and speakers 25, 26, 27, and 28. Furthermore, as is clear from comparing Figure 6 and Figure 2, memory 110 stores control program 114A instead of control program 114. Control program 114A is an example of a "program".

[0092] The control program 114A is a program that causes the processor 100 to function as the occupant detection unit 106, the driving state detection unit 107, and the display control unit 108A.

[0093] The display control unit 108A displays the selection screen G on each of the touch panels 13, 22, 23, and 24.

[0094] If the display control unit 108A detects a crew member P among those detected by the crew member detection unit 106, and the memory 110 does not store preference information J2 for that crew member P, it displays the first selection screen on each of the touch panels 13, 22, 23, and 24.

[0095] If the memory 110 has stored preference information J2 for all occupants P detected by the occupant detection unit 106, the display control unit 107A displays a second selection screen on each of the touch panels 13, 22, 23, and 24. In this case, the display control unit 108A sets a priority for displaying the icon IC for each of the touch panels 13, 22, 23, and 24, and displays the second selection screen based on the set priority.

[0096] More specifically, the display control unit 107A sets the priority of the occupant information R1 of the occupant P (hereinafter referred to as the "target occupant") seated in the corresponding seat for each of the touch panels 13, 22, 23, and 24 to be higher than the priority of the occupant information R1 of occupant P other than the target occupant. Then, for each of the touch panels 13, 22, 23, and 24, the display control unit 107A displays an icon IC based on the set priority and the occupant P's preference information J2.

[0097] The display control unit 107A sets a higher priority for setting the occupant information R1 of occupant P1 seated in the driver's seat 10A on the touch panel 13 than for setting the occupant information R1 of occupant P seated anywhere other than the driver's seat 10A. As a result, for example, when occupants P1, P2, P3, and P4 are detected as shown in Figure 1, the second selection screen displayed on the touch panel 13 will show the icon IC based on occupant information R1 of occupant P1 in the list display area A1 with the highest priority, followed by the icon ICs based on the occupant information R1 of the other occupants P with the next highest priority.

[0098] The display control unit 107A sets a higher priority for setting the occupant information R1 of occupant P seated in the passenger seat 10B on the touch panel 22 than for setting the occupant information R1 of occupant P seated in seats other than the passenger seat 10B. As a result, for example, when occupants P1, P2, P3, and P4 are detected as shown in Figure 1, the icon IC based on the occupant information R1 of occupant P2 is displayed with the highest priority on the second selection screen displayed on the touch panel 22, followed by the icon ICs based on the occupant information R1 of the other occupants P.

[0099] The display control unit 108A sets a higher priority for setting the occupant information R1 of occupant P3, who is seated in the rear right seat 10C, on the touch panel 23 than for setting the occupant information R1 of occupant P, who is seated in a seat other than the rear right seat 10C. As a result, for example, when occupants P1, P2, P3, and P4 are detected as shown in Figure 1, the icon IC based on the occupant information R1 of occupant P3 is displayed with the highest priority on the second selection screen displayed on the touch panel 23, followed by the icon ICs based on the occupant information R1 of the other occupants P.

[0100] The display control unit 108A sets a higher priority for setting the occupant information R1 of occupant P4 seated in the rear left seat 10D on the touch panel 24 than for setting the occupant information R1 of occupant P seated in a seat other than the rear left seat 10D. As a result, for example, when occupants P1, P2, P3, and P4 are detected as shown in Figure 1, the icon IC based on occupant information R1 of occupant P4 is displayed with higher priority on the second selection screen displayed by the touch panel 24 than the icon IC based on occupant information R1 of the other occupants P.

[0101] Next, the operation of the vehicle display device 19 in this embodiment will be explained with reference to Figure 5. When the vehicle display device 19 performs steps SA1 and SA2, it skips step SA3 and performs step SA4, then step SA5, or step SA6. In step SA6 of this embodiment, the display control unit 107A displays the second selection screen on each of the touch panels 13, 22, 23, and 24, as described above.

[0102] Furthermore, when one icon IC is selected by touch operation on the selection screen G displayed by the touch panel 13, the content output unit 105 receives and outputs the content corresponding to the selected icon IC via at least one of the touch panel 13 and the speaker 25. Furthermore, when one icon IC is selected by touch operation on the selection screen G displayed by the touch panel 22, the content output unit 105 receives and outputs the content corresponding to the selected icon IC via at least one of the touch panel 22 and the speaker 26. Furthermore, when one icon IC is selected by touch operation on the selection screen G displayed by the touch panel 23, the corresponding content output unit 105 receives and outputs the content corresponding to the selected icon IC via at least one of the touch panel 23 and the speaker 27. Furthermore, when one icon IC is selected by touch operation on the selection screen G displayed by the touch panel 24, the corresponding content output unit 105 receives and outputs the content corresponding to the selected icon IC via at least one of the touch panel 24 and the speaker 28.

[0103] [3. Other Embodiments] The embodiments described above are merely examples and can be modified and applied as needed.

[0104] In the embodiment described above, the case of a four-seater vehicle 1 was illustrated. However, the number of passengers that vehicle 1 can accommodate is not limited to four.

[0105] In the embodiments described above, a four-wheeled vehicle 1 was used as an example, but the number of wheels on the vehicle 1 is not limited to four.

[0106] In the embodiments described above, touch panels 13, 22, 23, and 24 were used as examples of the "display unit," but the "display unit" is not limited to touch panels; it may also be a display that does not have touch operation functionality but can be operated by operation keys or the like.

[0107] In the embodiment described above, the vehicle display device 19 is configured not to include a "display unit," but the vehicle display device 19 may also be configured to include a "display unit."

[0108] In the embodiment described above, the icon ICs are arranged horizontally on the selection screen G2, but the arrangement direction of the icon ICs is not limited to horizontal and may also be vertical. In this other embodiment, "prioritizing display" means, for example, displaying at the top.

[0109] In the selection screen G of the embodiment described above, the icons IC are displayed in a list, with each content source separated into different rows. In the selection screen G of other embodiments, the icons IC may be displayed in a list of N rows and M columns without separating each content source into different rows. N and M are two or more integers. In these other embodiments, "prioritizing display" in the selection screen G means that displaying as high as possible is the first priority, and displaying as far to the left as possible in a single row is the second priority.

[0110] In the embodiment described above, the icon IC is displayed based on the driving state of vehicle 1 and the matching of preferred objects. In other embodiments, the icon IC may be displayed based on either the driving state of vehicle 1 or the matching of preferred objects.

[0111] In the embodiment described above, the driving state detection unit 106 detects the driving state of the vehicle 1 based on the detection result of the shift position sensor 22. In other embodiments, the vehicle 1 may be provided with a vehicle speed sensor, and the driving state detection unit 106 may detect the driving state of the vehicle 1 using the vehicle speed sensor.

[0112] In the above-described embodiment, the occupant P is detected from images captured by cameras 15, 17, and 18. In other embodiments, the occupant detection unit 106 may detect the occupant P by a method other than the images captured by cameras 15, 17, and 18. For example, if the vehicle display device 19 is informed of who is boarding at the time of boarding, the occupant detection unit 106 may detect the occupant P based on this input. In another embodiment, if a microphone for collecting the occupant P's voice is provided in the vehicle 1, the occupant detection unit 106 may detect the occupant P based on the number and type of voices collected by the microphone. In yet another embodiment, the detection of the occupant P seated in the driver's seat 10A may be performed using an FOB key.

[0113] In the embodiment described above, the seat position of occupant P is detected from the images captured by cameras 15, 17, and 18. In other embodiments, the occupant detection unit 106 may detect the seat position of occupant P by a method other than the images captured by cameras 15, 17, and 18. For example, if input is given to the vehicle display device 19 indicating who will sit in which seat when boarding, the occupant detection unit 106 may detect occupant P based on this input. In other embodiments, the seat position of occupant P may be detected based on the voice of occupant P and the position of the microphone that picks up occupant P's voice most strongly.

[0114] In the embodiment described above, the vehicle display device 19 is configured to have three application programs installed for using the content. In other embodiments, the number of such application programs installed in the vehicle display device 19 may be two or fewer, or four or more.

[0115] The processor 100 may consist of multiple processors or a single processor. The processor 100 may also be hardware programmed to implement the functional units described above. In this case, these processors may consist of, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0116] Furthermore, the configuration of each part of Vehicle 1 shown in Figure 2 is merely an example, and the specific implementation is not particularly limited. In other words, it is not necessarily required that hardware corresponding to each part be implemented individually; it is certainly possible to configure a system where a single processor executes a program to realize the functions of each part. Also, in the embodiments described above, some of the functions realized by software may be implemented as hardware, or conversely, some of the functions realized by hardware may be implemented as software.

[0117] Furthermore, the operation steps shown in Figures 5 and 6 are divided according to the main processing content, and the present invention is not limited by the way the processing units are divided or by their names. Depending on the processing content, it may be further divided into more steps. Alternatively, it may be divided so that one step unit includes even more processing. Also, the order of the steps may be rearranged as appropriate, as long as it does not impede the spirit of the present invention.

[0118] Furthermore, when the control method for the vehicle display device 19 described above is implemented using the processor 100, the program to be executed by the processor 100 can be configured as a recording medium or a transmission medium for transmitting this program. In other words, the control program 114 can also be implemented by recording it on a portable information recording medium. Examples of information recording media include magnetic recording media such as hard disks, optical recording media such as CDs, and semiconductor storage devices such as USB (Universal Serial Bus) memory and SSDs (Solid State Drives), but other recording media can also be used.

[0119] [4. Configurations supported by the above embodiments] The above embodiment supports the following configuration.

[0120] (Composition 1) A vehicle display device comprising: a display control unit that displays icons indicating the content of available content in the vehicle using a display unit provided inside the vehicle; an occupant detection unit that detects occupants of the vehicle; and a storage unit that stores occupant information relating to the occupants of the vehicle, wherein the display control unit acquires occupant information corresponding to occupants detected by the occupant detection unit from the storage unit, and displays the icons based on the acquired occupant information and content information relating to the content. According to the vehicle display device of configuration 1, since it can display icons indicating the content of the content while taking into account information about the vehicle occupants, it can appropriately display icons indicating the content of the content according to the vehicle occupants.

[0121] (Configuration 2) The vehicle display device according to Configuration 1, wherein the occupant information includes preference information indicating the object of preference, the display control unit stores the occupant information for all of the multiple occupants detected by the occupant detection unit, and if there is a matching object of preference among the occupants detected by the occupant detection unit, the display control unit displays the icon for one of the contents based on the preference information indicating the object of preference with the largest number of matches. According to the vehicle display device of configuration 2, icons indicating the content preferred by multiple occupants can be displayed, thereby promoting the use of content among multiple occupants.

[0122] (Composition 3) A vehicle display device according to configuration 1 or configuration 2, comprising a driving state detection unit for detecting the driving state of the vehicle, wherein the display control unit, when the occupant detection unit detects multiple occupants, sets a priority for displaying the icons based on the driving state of the vehicle detected by the driving state detection unit for multiple occupant information obtained from the storage unit, and displays the icons based on the set priority. The occupants most likely to use the content may differ depending on the vehicle's driving conditions. For example, when the driver is at the wheel, the driver is less likely to use the content, while other occupants are more likely to use it. Therefore, the vehicle display device in configuration 3 can set a priority for displaying icons based on the vehicle's driving conditions, allowing icons to be displayed according to the occupants most likely to use the content, depending on the vehicle's driving conditions. Thus, icons indicating the content can be appropriately displayed to the vehicle's occupants, and the use of the content can be promoted to occupants most likely to use it.

[0123] (Composition 4) The vehicle display device according to configuration 3, wherein the display control unit, when the driving state detection unit detects that the driving state of the vehicle is a manual driving state in which an occupant seated in the driver's seat is manually driving, sets a higher priority for the occupant information of an occupant detected outside the driver's seat than the priority set for the occupant information of an occupant detected in the driver's seat. When a vehicle is in manual driving mode, the driver is less likely to use the content. Therefore, according to the vehicle display device of configuration 4, icons can be displayed according to the occupants who are more likely to use the content when the vehicle is in manual driving mode.

[0124] (Composition 5) The vehicle display device according to configuration 3 or 4, wherein the display control unit, when the driving state detection unit detects that the driving state of the vehicle is not a manual driving state in which an occupant seated in the driver's seat is manually driving, sets the priority set for the occupant information of an occupant detected in the driver's seat higher than the priority set for the occupant information of an occupant detected outside the driver's seat. The driver of a vehicle is likely to be the owner of the vehicle. Therefore, if the vehicle is not in manual driving mode, the driver is likely to use the content. Accordingly, the vehicle display device of configuration 5 can display icons according to the occupants who are likely to use the content when the vehicle is not in manual driving mode.

[0125] (Composition 6) The vehicle display device according to any one of configurations 1 to 5, wherein the display control unit displays the icon without relying on the occupant information if the occupant detected by the occupant detection unit includes an occupant whose occupant information is not stored in the storage unit. If the occupant detection unit detects occupants for whom occupant information is not stored, the vehicle may include occupants who do not normally ride in the vehicle, such as guests. Therefore, the vehicle display device of configuration 6 can prevent occupants who do not normally ride in the vehicle from knowing what kind of content is suitable for occupants who normally ride in the vehicle.

[0126] (Composition 7) The vehicle display device according to any one of configurations 1 to 6, wherein the vehicle is provided with a display unit for each seat, the occupant detection unit detects an occupant for each seat of the vehicle, the display control unit acquires occupant information for each seat of the vehicle, and for each seat of the vehicle, displays the corresponding icon on the display unit based on the acquired occupant information. When multiple displays are provided for each seat in a vehicle, the occupant using content on a particular display is likely to be the occupant seated in the seat corresponding to that display. Therefore, the vehicle display device of configuration 7 can display an icon indicating the content for each display, taking into account information about the occupant in the corresponding seat. Thus, even when a display is set up for each seat, the icon indicating the content can be appropriately displayed according to the occupant of the vehicle.

[0127] (Composition 8) A control method for a vehicle display device, comprising: a storage unit for storing occupant information relating to occupants of a vehicle equipped with a display unit, the method comprising: detecting occupants of the vehicle; obtaining occupant information corresponding to the detected occupants from the storage unit; and displaying icons indicating the content on the display unit based on the obtained occupant information and content information relating to content available in the vehicle. The control method for the vehicle display device of configuration 8 produces the same effect as the vehicle display device of configuration 1.

[0128] (Composition 9) A program that causes the processor of a vehicle display device, which includes a storage unit for storing occupant information relating to occupants of a vehicle equipped with a display unit, to function as an occupant detection unit for detecting occupants of the vehicle, and a display control unit for acquiring the occupant information corresponding to the occupants detected by the occupant detection unit from the storage unit, and for displaying icons indicating the content on the display unit based on the acquired occupant information and content information relating to content available in the vehicle. According to the program of configuration 9, it produces the same effect as the vehicle display device of configuration 1. [Explanation of Symbols]
