[0014] (Summary of the Disclosure) In recent years, the use of multi-displays in vehicle interiors through integrated cockpits has been progressing. As a result, the opportunities to display information on display devices have increased due to the large scale and diversification of in-vehicle systems. Therefore, display methods aimed at efficiently transmitting information to users such as drivers have been studied.

[0015] For example, when various systems such as a camera and a navigation system attempt to display an image such as a message on the same display device, the amount of information in the image displayed by the display device increases. This may impair visibility. For example, in the display device disclosed in the above-mentioned Patent Document 1, when a user is gazing at a HUD (Head Up Display) and multiple events occur at the same time, if the HUD attempts to display information corresponding to each of the multiple events as an image, the amount of information in the image increases and visibility decreases.

[0016] Therefore, a method of changing the manner in which information is displayed (for example, the amount of information and / or whether or not information is displayed) according to the priority of the information, such as displaying only the information with the highest priority, is conceivable. However, with such a method, when there is a lot of information with high priority, there is a possibility that information with low priority will not be displayed.

[0017] Furthermore, in the display control device disclosed in Patent Document 2, too, a large amount of information is displayed on the same display device, which may reduce visibility.

[0018] Therefore, an object of the present disclosure is to provide a display control device and the like that can suppress a decrease in the visibility of information displayed on a display device and suppress a decrease in the amount of information notified to a user.

[0019] A display control device according to one embodiment of the present disclosure includes a determination unit that determines whether an amount of information of first display information displayed on a first display device is equal to or greater than a predetermined threshold, and a control unit that, when the determination unit determines that the amount of information of the first display information is equal to or greater than the predetermined threshold, (i) causes the first display device to display first notification information related to a predetermined event and the first display information, and (ii) causes a second display device different from the first display device to display second notification information related to the predetermined event, which includes the first notification information and has a larger amount of information than the first notification information.

[0020] According to this, in a display device that displays a large amount of information, for example, when a predetermined event occurs, new information related to the predetermined event is notified to the user only in a simplified form. Therefore, it is possible to notify the user of new information while preventing the amount of information displayed by the display device from becoming too large. In addition, by displaying details of new information on a display device that does not display a large amount of information, the user can grasp the details of the new information at a desired timing. Therefore, according to the display control device according to one aspect of the present disclosure, it is possible to suppress a decrease in visibility of information displayed on the display device and a decrease in the amount of information notified to the user.

[0021] Also, for example, the control unit notifies a user of first association information indicating that the first notification information and the second notification information are associated with each other.

[0022] This allows the user to easily know on which display device the details of the simplified information displayed on the first display device are displayed.

[0023] Also, for example, the determination unit determines whether or not the second display information displayed on the second display device is related to the second notification information, and when the determination unit determines that the second display information and the second notification information are related to each other, the control unit notifies a user of second related information indicating that the second display information and the second notification information are related to each other.

[0024] For example, the second display device may constantly display an image of the surroundings of the vehicle captured by the imaging device. In such a case, an event related to the image may occur, such as a person approaching the vehicle. In such a case, information indicating the relationship between the information to be newly displayed on the second display device and the information already displayed on the second display device is notified to the second display device, so that the user can more easily grasp the details of the information to be newly displayed on the second display device.

[0025] The display device further includes a determination unit that selects one display device from among the plurality of display devices based on line-of-sight information indicating a line-of-sight direction of a user, and determines the selected display device as the first display device.

[0026] According to this, the first notification information can be displayed on a display device close to the position where the user is looking, so that new information about a predetermined event can be quickly notified to the user.

[0027] Also, for example, the control unit determines the amount of information of the first notification information based on the amount of information of the first display information, and causes the first display device to display the first notification information of the determined amount of information.

[0028] According to this, information corresponding to the amount of information displayed on the first display device is newly displayed on the first display device, so that an appropriate amount of information can be further displayed on the first display device.

[0029] Also, for example, the first display device and the second display device are disposed in a vehicle, and the determination unit sets the predetermined threshold value based on a traveling state of the vehicle.

[0030] For example, when the vehicle speed is high, it is expected that the driver will have to pay more attention to driving compared to when the vehicle speed is low, and it is therefore considered that it will be difficult for the driver to obtain information from the display device. Therefore, by appropriately setting the amount of information to be displayed on the first display device based on the vehicle's running conditions such as the vehicle speed, the information displayed on the first display device can be more easily understood by the user.

[0031] Also, for example, when the determination unit determines that the amount of information of the first display information is equal to or greater than the specified threshold, the control unit causes the first display device to display the second notification information, and when a specified condition is satisfied, causes the first display device to display the first notification information instead of the second notification information, and also causes the second display device to display the second notification information.

[0032] According to this, for information that needs to be notified to the user as a particular priority, details of that information are first notified to the user, and when certain conditions are met, the amount of information is reduced, making it possible to convey more information to the user quickly while preventing a decrease in visibility of the information displayed on the first display device.

[0033] Also, for example, when the specified condition is satisfied is at least one of when the control unit acquires operation information indicating that a user has performed an operation based on the second notification information and when a specified time has elapsed since the control unit caused the first display device to display the second notification information.

[0034] This makes it possible to reduce the amount of information displayed on the first display device at an appropriate time.

[0035] Also, for example, when the determination unit determines that the amount of information of the first display information is less than the predetermined threshold, the control unit causes the first display device to display the second notification information.

[0036] This makes it possible to prevent the same information from being unnecessarily displayed on a plurality of display devices.

[0037] In addition, a display control method according to one embodiment of the present disclosure determines whether the amount of information of first display information displayed on a first display device is equal to or greater than a predetermined threshold, and if it is determined that the amount of information of the first display information is equal to or greater than the predetermined threshold, (i) displays first notification information regarding a predetermined event and the first display information on the first display device, and (ii) displays second notification information regarding the predetermined event, which includes the first notification information and has a larger amount of information than the first notification information, on a second display device different from the first display device.

[0038] A program according to an aspect of the present disclosure is a program for causing a computer to execute a display control method according to an aspect of the present disclosure.

[0039] These provide the same effects as the above-mentioned display control device.

[0040] In addition, these comprehensive or specific aspects may be realized by a system, a method, an integrated circuit, a computer program, or a non-transitory recording medium such as a computer-readable CD-ROM, or may be realized by any combination of the system, the method, the integrated circuit, the computer program, or the non-transitory recording medium.

[0041] Hereinafter, the embodiment will be specifically described with reference to the drawings.

[0042] In addition, the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement and connection forms of components, steps, order of steps, etc. shown in the following embodiments are examples and are not intended to limit the present disclosure. In addition, among the components in the following embodiments, components that are not described in an independent claim showing the highest concept are described as optional components. In addition, each figure is a schematic diagram and is not necessarily illustrated strictly. Therefore, for example, the scale, etc., does not necessarily match in each figure. In addition, the same reference numerals are given to the same components in each figure.

[0043] (Embodiment) [composition] Fig. 1 is a diagram illustrating the interior of a vehicle 10 according to an embodiment. Fig. 2 is a block diagram illustrating the configuration of a display control device 100 according to an embodiment.

[0044] The display control device 100 is a control device that controls a plurality of display devices to control images displayed on the plurality of display devices. In this embodiment, the display control device 100 controls the display device 300, the display device 310, and the display device 320.

[0045] The display device 300, the display device 310, and the display device 320 are each a control device that displays an image.

[0046] Note that the display device 300, the display device 310, and the display device 320 may each be any device capable of displaying an image, such as a liquid crystal display or a HUD (Head Up Display), and are not particularly limited. In this embodiment, the display device 300 is a HUD. Also, in this embodiment, the display device 310 and the display device 320 are liquid crystal displays. Also, in this embodiment, the display device 320 is a display device included in the navigation system 220 that displays the travel route of the vehicle 10 obtained by the navigation system 220, etc. In this manner, the display devices controlled by the display control device 100 may include display devices included in other systems.

[0047] In the following description, an image displayed by the display device 300 is referred to as a display image 500, and an image displayed by the display device 310 is referred to as a display image 510, as shown in FIG.

[0048] In a display system 400 including a display control device 100, an image including information obtained by a detection device 200 such as an imaging device 210 and a navigation system 220 is displayed on at least one of the display devices 300, 310, and 320, thereby notifying a user such as a driver of the information. The display control device 100 acquires the information from the detection device 200, and causes at least one of the display devices 300, 310, and 320 to display an image including the acquired information.

[0049] For example, when a predetermined event such as route guidance, the presence of an obstacle, or speeding has occurred based on the detected information, the detection device 200 outputs information about the predetermined event (for example, information indicating the predetermined event) to the display control device 100. For example, when the detection device 200 determines that there is an obstacle on the travel route of the vehicle 10, it outputs information indicating that there is an obstacle on the travel route of the vehicle 10. When the display control device 100 acquires information indicating that there is an obstacle on the travel route of the vehicle 10, it causes the display device 300, 310, and / or 320 to display information indicating that there is an obstacle on the travel route of the vehicle 10.

[0050] The display system 400 is arranged, for example, in a vehicle 10. Specifically, the display devices 300 to 320 controlled by the display control device 100 are arranged in the vehicle 10 (that is, the same vehicle).

[0051] Although not shown, in this embodiment, the display control device 100 and the detection device 200 are also disposed in the vehicle 10.

[0052] The vehicle 10 is, for example, a car, a motorcycle, or the like, and is a car in this embodiment. The vehicle 10 may also be a ship, an aircraft, or the like.

[0053] As shown in FIG. 2, the display system 400 includes a detection device 200, a display control device 100, a display device 300, a display device 310, a display device 320, and an audio device 330.

[0054] The detection device 200 is a detection device that detects various information. For example, the detection device 200 acquires information related to a predetermined event. The detection device 200 acquires information related to the vehicle 10, for example. The information related to the vehicle 10 includes, for example, position information of the vehicle 10, or information about obstacles located around the vehicle 10.

[0055] The detection device 200 includes an imaging device 210 and a navigation system 220 .

[0056] The imaging device 210 is a camera that captures an image of the surroundings of the vehicle 10. The imaging device 210 outputs, for example, data of an image (image data) generated by capturing an image of the surroundings of the vehicle 10 to the display control device 100.

[0057] The imaging device 210 may determine, based on the imaging result, whether or not an obstacle or the like is located around the vehicle 10. In this case, the imaging device 210 may output information indicating the determination result.

[0058] The navigation system 220 is a device that acquires information such as a driving route along which the vehicle 10 travels. The navigation system 220 has a wireless communication interface such as an antenna and a wireless communication circuit, receives map information indicating a map of the road along which the vehicle 10 travels from an external device, and outputs the received map information to the display control device 100. The navigation system 220 also receives status information indicating the status of the road along which the vehicle 10 travels from an external device that is a computer such as a server device, and outputs the received status information to the display control device 100. The navigation system 220 also calculates a driving route, and outputs information indicating the calculated driving route to the display control device 100.

[0059] The detection device 200 may include a GPS (Global Positioning System) receiver. Alternatively, the detection device 200 may include an obstacle sensor that detects the position and distance of an object such as an obstacle around the vehicle 10. Examples of the obstacle sensor include an infrared sensor, an electromagnetic wave sensor, and / or a millimeter wave sensor. Alternatively, the detection device 200 may include a yaw rate sensor that measures the yaw rate of the vehicle 10. Alternatively, the detection device 200 may include a speed sensor that detects the speed of the vehicle 10. Alternatively, the detection device 200 may include a steering angle sensor that measures the steering angle of a steering wheel or the like. Alternatively, the detection device 200 may be an external device such as a VICS (registered trademark) (Vehicle Information and Communication System). The detection device 200 may include one or more of these sensors in any combination. The detection device 200 and the display control device 100 may be connected to each other so as to be able to communicate with each other, and may be connected to each other so as to be able to communicate with each other via wired communication or wireless communication.

[0060] In addition, the detection device 200 may be disposed in the vehicle 10 or outside the vehicle 10.

[0061] Furthermore, the detection device 200 may detect the gaze direction of the user in addition to the predetermined event. For example, the detection device 200 further includes an imaging device that captures an image of the user's face. The imaging device calculates the gaze direction of the user based on the image capture result of the user's face, and outputs gaze information indicating the calculated gaze direction to the display control device 100.

[0062] The display control device 100 is a control device that controls the detection device 200, the display device 300, the display device 310, the display device 320, and the audio device 330. The display control device 100 is realized as a computer that includes, for example, a communication interface for communicating with the detection device 200, the display devices 300 to 320, and the audio device 330 included in the display system 400, a non-volatile memory that stores a program, a volatile memory that is a temporary storage area for executing the program, an input / output port for transmitting and receiving signals, a processor that executes the program, and the like.

[0063] The display control device 100, the detection device 200, the display device 300, the display device 310, the display device 320, and the audio device 330 may be connected so as to be capable of communication, and may be connected so as to be capable of wired communication, or may be connected so as to be capable of wireless communication.

[0064] The display control device 100 includes an acquisition unit 110, a determination unit 120, a determination unit 130, a control unit 140, and a storage unit 150.

[0065] The acquisition unit 110 is a processing unit that acquires information from the detection device 200. For example, the acquisition unit 110 acquires information related to a predetermined event from the detection device 200. Alternatively, for example, the acquisition unit 110 acquires gaze information indicating a user's gaze direction from the detection device 200. Alternatively, for example, the acquisition unit 110 acquires information indicating a user's action (for example, action information) from a user interface such as a touch panel that accepts input from the user.

[0066] The determination unit 120 is a processing unit that determines a display device that displays information related to a predetermined event.

[0067] In the following, the display device that displays information related to a predetermined event, which is determined by the determination unit 120, is also referred to as a first display device. For example, the determination unit 120 selects one display device from among a plurality of display devices (e.g., display devices 300 to 320) based on line-of-sight information indicating the line-of-sight direction of the user, and determines the selected display device as the first display device.

[0068] According to this, the first notification information can be displayed on a display device close to the position where the user is looking, so that new information about a predetermined event can be quickly notified to the user.

[0069] Furthermore, the determination unit 120 may determine a priority order for displaying information related to a predetermined event for the display devices 300 to 320. For example, the determination unit 120 sets the priority order of the display devices 300 to 320 in descending order of distance from a target position located in the user's line of sight based on the line of sight information.

[0070] Alternatively, the determination unit 120 may set the priority order based on the amount of information contained in the images displayed on the multiple display devices 300 to 320. For example, the determination unit 120 may set the priority order in ascending order of the amount of information contained in the images displayed on the multiple display devices 300 to 320.

[0071] Alternatively, the determination unit 120 may set the priority order based on the specifications (e.g., resolution and frame rate) of the multiple display devices 300 to 320. For example, the determination unit 120 may set the priority order of the multiple display devices 300 to 320 in descending order of resolution.

[0072] The priority order and the first display device may be arbitrarily determined in advance.

[0073] Moreover, the information displayed on the display devices 300-320 (i.e., information included in the images displayed on the display devices 300-320) is information notified to the user by characters, figures, etc. The information may include, for example, photographs and images captured by the imaging device 210.

[0074] The amount of information is the amount of information to be notified to the user, expressed by characters, figures, etc. The amount of information is determined based on, for example, the number of characters, figures, etc., or the area of ​​the characters, figures, etc. (for example, the number of pixels in an image for expressing the characters, figures, etc.).

[0075] For example, the information display method is predefined, such as (I) detailed character string and graphic, (II) simplified character string and graphic, (III) detailed character string only, (IV) simplified character string only, and (V) graphic only. For example, the order of the amount of information is predefined in order of (I) to (V).

[0076] For example, when the information relating to a specified event indicates that a pedestrian is approaching from the front left side of the vehicle, at least one of display devices 300, 310, and 320 displays the information relating to the specified event using any of the display methods (I) to (V) above.

[0077] 3A to 3E are diagrams showing specific examples of the notification information according to the embodiment.

[0078] The notification information is information about a predetermined event. For example, when information indicating that a pedestrian is approaching from the front left side of the vehicle is displayed as notification information as information about the predetermined event, the notification information is displayed by any combination of one or more of the notification information 650 to 670. For example, the above (I) is a combination of the notification information 650 and the notification information 670. For example, the above (II) is a combination of the notification information 660 and the notification information 670. For example, the above (III) is only the notification information 650. For example, the above (IV) is only the notification information 660. For example, the above (V) is only the notification information 670. For example, when notifying the user of detailed information about the predetermined event, the above (I) is selected and the notification information 650 and the notification information 670 are displayed on any one of the display device 300, the display device 310, and the display device 320. On the other hand, for example, when the user is to be notified of simplified information regarding a specific event, the above (V) is selected and notification information 670 is displayed on one of display devices 300, 310, and 320.

[0079] The amount of information may be set arbitrarily based on, for example, the complexity of the figure.

[0080] The determination unit 130 is a processing unit that determines the amount of information (display information) included in the images displayed on the display devices 300, 310, and 320. Specifically, the determination unit 130 determines whether or not the amount of information of the display information (first display information) included in the first display image displayed on the first display device determined by the determination unit 120 is equal to or greater than a predetermined threshold. For example, the determination unit 130 determines whether or not the amount of information of the first display information included in the first display image displayed on the first display device is equal to or greater than a predetermined threshold.

[0081] The first display image is the image displayed on the first display device.

[0082] The display information is, for example, notification information that has already been displayed, but may also include information unrelated to a specific event, such as an image captured by the image capture device 210, in addition to the notification information.

[0083] Moreover, the predetermined threshold may be arbitrarily determined in advance, and is not particularly limited. Alternatively, for example, the determination unit 130 may set the predetermined threshold based on the traveling state of a vehicle in which the multiple display devices controlled by the display control device 100 are arranged. In this embodiment, the display devices 300 to 320 are arranged in the vehicle 10, that is, in the same vehicle. For example, the determination unit 130 sets the predetermined threshold based on the traveling state of the vehicle 10. Alternatively, the predetermined threshold may be set from the specifications of the display devices 300 to 320, such as the resolution or frame rate.

[0084] The running state is, for example, a state related to the running of the vehicle 10, such as the speed, acceleration, rotation speed, and rotation angle of the vehicle 10. For example, the determination unit 130 sets the predetermined threshold lower as the speed of the vehicle 10 is faster.

[0085] The information indicating the correlation between the driving state and the threshold value may be arbitrarily determined in advance and stored in the storage unit 150, and is not particularly limited.

[0086] The control unit 140 is a processing unit that controls the display device 300, the display device 310, the display device 320, and the sound device 330. For example, the control unit 140 controls the display device 300, the display device 310, the display device 320, and the sound device 330 based on information obtained from the detection device 200. Specifically, when the determination unit 130 determines that the amount of information of the first display information is equal to or greater than a predetermined threshold, the control unit 140 (i) causes the first display device to display the first notification information and the first display information related to a predetermined event. In addition, when the determination unit 130 determines that the amount of information of the first display information is equal to or greater than a predetermined threshold, the control unit 140 (ii) causes a second display device different from the first display device to display second notification information related to a predetermined event that includes the first notification information and has a larger amount of information than the first notification information.

[0087] The first notification information and the second notification information are both information related to the same predetermined event. For example, when the first notification information is only notification information 670, the second notification information includes information having the same form (for example, characters and figures) as the first notification information, such as notification information 650 and notification information 670.

[0088] According to this, in a display device that displays a relatively large amount of information among the multiple display devices, when a specific event occurs, for example, new information related to the specific event is notified to the user only in simplified form, so that the amount of information displayed by the display device can be prevented from becoming too large, and the user can be notified of new information. Also, by displaying details of the new information on a display device that displays a relatively small amount of information, the user can grasp the details of the new information at the desired timing. Therefore, according to the display control device according to one aspect of the present disclosure, it is possible to suppress a decrease in the visibility of the information displayed on the display device and a decrease in the amount of information notified to the user.

[0089] The control unit 140 may determine the amount of information of the first notification information based on the amount of information of the first display information, and cause the first display device to display the first notification information of the determined amount of information. For example, the control unit 140 determines the amount of information of the first notification information to be smaller as the amount of information of the first display information increases.

[0090] According to this, information corresponding to the amount of information displayed on the first display device is newly displayed on the first display device, so that an appropriate amount of information can be further displayed on the first display device.

[0091] The amount of information of the first notification information relative to the amount of information of the first display information may be determined arbitrarily. The amount of information of the first notification information relative to the amount of information of the first display information may be determined to change in proportion to the amount of information, or may be determined in stages.

[0092] Furthermore, when the determination section 130 determines that the amount of information in the first display information is less than a predetermined threshold, the control section 140 may cause the first display device to display the second notification information.

[0093] This makes it possible to prevent the same information from being unnecessarily displayed on a plurality of display devices.

[0094] Also, for example, when the content indicated by the notification information displayed on the first display device is resolved, the control unit 140 deletes the notification information from the first display image. For example, when the notification information is information indicating speeding, the control unit 140 deletes the notification information from the display information when the speeding is resolved. For example, when the determination unit 130 determines that the amount of information of the first display information is equal to or greater than a predetermined threshold and causes the first display device to display the first notification information, the control unit 140 may cause the first display device to display the second notification information instead of the first notification information when the determination unit 130 determines that the amount of information of the first display information is less than the predetermined threshold. Also, in this case, the control unit 140 may delete the second notification information displayed on the second display device.

[0095] In the following description, the first display device is referred to as display device 300, and the second display device is referred to as display device 310.

[0096] 4A, 4B, 5A, and 5B are diagrams showing specific examples of display images 500 and 510 according to the embodiment.

[0097] Specifically, Figures 4A and 4B are figures showing display images 500, 510 before acquisition unit 110 acquires information regarding the additional specified event, and Figures 5A and 5B are figures showing display images 500, 510 after acquisition unit 110 acquires information regarding the additional specified event.

[0098] 4A , for example, it is assumed that display image 500 includes notification information 600, 610, and 620 before acquisition unit 110 acquires information related to an additional predetermined event. That is, in this case, for example, the display information included in display image 500 is notification information 600, 610, and 620.

[0099] For example, the notification information 600 is warning information that warns the user when the speed of the vehicle 10 exceeds a specified speed.

[0100] Moreover, for example, the notification information 610 is navigation information that guides the user along a driving route.

[0101] Moreover, for example, the notification information 620 is warning information that alerts the user that the vehicle 10 is about to deviate from the lane.

[0102] Note that, like notification information 620, the notification information that control unit 140 causes the display device to display may be displayed by thickening lines, encircling, or coloring the displayed image.

[0103] 4B, for example, it is assumed that display image 510 before acquisition unit 110 acquires information related to an additional predetermined event does not include notification information and only displays an image obtained by imaging device 210. In this embodiment, display image 510 includes object 20, which is a pedestrian.

[0104] 4A and 4B, for example, it is assumed that the target 20 approaches the travel route of the vehicle 10 to a predetermined distance. In other words, it is assumed that the detection device 200 detects a predetermined event, "the target 20 approaches the travel route of the vehicle 10 to a predetermined distance." In this case, for example, the detection device 200 outputs information related to the predetermined event (for example, information indicating that the predetermined event has occurred) to the display control device 100. The control unit 140 controls the display devices 300, 310, 320 based on the information related to the predetermined event.

[0105] In this embodiment, for example, the control unit 140 causes the display device 300 to display, as notification information (first notification information), simplified information indicating that the target 20 has approached within a predetermined distance from the travel route of the vehicle 10. For example, as shown in Fig. 5A, the display image 500 includes notification information 630 as the first notification information indicating that the target 20 has approached within a predetermined distance from the travel route of the vehicle 10.

[0106] Furthermore, for example, the control unit 140 causes the display device 300 to display detailed information indicating that the target 20 has approached the driving route of the vehicle 10 to within a predetermined distance as notification information (second notification information). For example, as shown in Fig. 5B, the display image 510 includes notification information 640 as the second notification information indicating that the target 20 has approached the driving route of the vehicle 10 to within a predetermined distance.

[0107] The second notification information includes the first notification information. In this embodiment, the notification information 640 includes the notification information 630.

[0108] The predetermined distance may be determined arbitrarily in advance.

[0109] Furthermore, the control unit 140 causes the display device 300 and the display device 310 to display a frame (related information 800 and related information 810) of lines of the same color and shape so as to surround the notification information 630 displayed on the display device 300 and the notification information 640 displayed on the display device 310. In this way, the control unit 140 notifies the user that the first notification information and the second notification information are related to each other. The frame is an example of related information (first related information). In this embodiment, the notification information 630 and the notification information 640 are surrounded by a dashed frame. In this way, for example, the control unit 140 notifies the user of the first related information indicating that the first notification information and the second notification information are related to each other. In this embodiment, the control unit 140 notifies the user of the first related information by causing the display device 300 to display the related information 810 and the display device 310 to display the related information 820.

[0110] When attempting to notify the driver of the approach of a pedestrian, multiple messages are displayed simultaneously on the same display device, and the display image displayed by the display device becomes cluttered. This reduces the visibility of the information. Furthermore, in the case where the display device is a HUD, if the display image displayed by the display device becomes cluttered, it becomes difficult to see ahead of the vehicle 10. Therefore, for example, the message (information) displayed on the display device 300 is switched to a simple one, details of the message are displayed on the display device 310, and further, the user is informed of the relationship between the message displayed on the display device 300 and the message displayed on the display device 310 (i.e., that these messages are related) by a graphic such as a frame of the same color and / or a notification by sound.

[0111] This allows the user to easily know on which display device the details of the simplified information displayed on the display device 300 are being displayed.

[0112] Moreover, the notification information 640 is information indicating that the target 20 has approached the travel route of the vehicle 10 to a predetermined distance. Therefore, the control unit 140 notifies the user that the second notification information and the target 20 are related to each other by displaying a frame (related information 810 and related information 820) on the display device 310 in the same color and shape so as to surround the notification information 640 displayed on the display device 310 and the target 20 displayed on the display device 310. The frame is an example of related information (second related information). In this embodiment, the notification information 640 and the target 20 are surrounded by a dashed frame. In this way, for example, the determination unit 130 determines whether or not the second display information (specifically, information included in the display image 510 shown in FIG. 4B) displayed on the second display device (for example, the display device 310) is related to the second notification information. In this case, for example, when the determination unit 130 determines that the second display information and the second notification information are related to each other, the control unit 140 notifies the user of the second related information indicating that the second display information and the second notification information are related to each other. In this embodiment, the control unit 140 notifies the user of the second related information by causing the display device 310 to display the related information 810 and the related information 820.

[0113] For example, an image of the surroundings of vehicle 10 captured by imaging device 210 (display image 510 shown in FIG. 4B in this embodiment) and the like are constantly displayed on display device 310. In such a case, an event related to the image may occur, such as an object 20 approaching vehicle 10. In such a case, second related information indicating the relationship between notification information (e.g., notification information 640) newly displayed on display device 310 and the information already displayed may be notified by display device 310, thereby making it easier for the user to grasp the details of the notification information newly displayed on display device 310.

[0114] The manner in which the related information is notified to the user may be any manner such as characters, figures, sounds, and / or blinking of a display. For example, although the related information is shown by a broken line in the above, it may be a line with a color such as a red line or a blue line, may be shown by unifying the characters in a color such as red or blue, or may be shown by sound. For example, the control unit 140 causes at least one of the display device 300, the display device 310, the display device 320, and the audio device 330 to notify the related information.

[0115] For example, the control unit 140 may control the audio device 330 at the timing when the notification information 630 is displayed on the display device 300 to output information related to a predetermined event, such as "A pedestrian is approaching. Please check the left front." Alternatively, for example, the control unit 140 may control the audio device 330 at the above timing to notify the user that information related to the notification information 630 is displayed on the display device 310, such as "A pedestrian is approaching. Please check the left side of the display for details.", that is, to notify the user of the first related information by voice. Alternatively, for example, the display system 400 may include audio devices (for example, speakers) at a position adjacent to the display device 300, a position adjacent to the display device 310, and a position adjacent to the display device 320. For example, the control unit 140 may notify the user of the related information by voice from an audio device adjacent to the display device that displays the second notification information. Also, for example, like notification information 690 shown in Fig. 3E, the first notification information may be displayed as an arrow (left side in the example shown in Fig. 3E) indicating the position where the second notification information is displayed, thereby indicating the position of the second notification information. In this example, the figure that looks like a left arrow is the first related information.

[0116] Alternatively, for example, the notification information 630 and the notification information 640 may be flashed at the same timing to notify the user that the notification information 630 and the notification information 640 are related to each other.

[0117] The related information notified to the user may be realized by combining two or more of the specific examples described above.

[0118] 4A to 5B are merely examples, and the notification information and related information are not limited to these. Any characters, figures, and the like may be used as the notification information and related information.

[0119] The predetermined event may be arbitrarily determined in advance and is not particularly limited. For example, when the navigation system 220 or the like detects "an instruction to turn left at an intersection 1.1 m ahead" as the predetermined event, the control unit 140 may cause the display device 300 to display the notification information 680 including the first related information such as "navigation screen" and cause the display device 320 to display the notification information 610.

[0120] Furthermore, the control unit 140 may determine a notification mode (output mode) for notifying the user of information relating to a predetermined event based on the priority of the information.

[0121] FIG. 6 is a diagram showing a specific example of an output mode of information according to priority.

[0122] For example, when the priority of information relating to a predetermined event acquired by the acquisition unit 110 is high (for example, priority "high" in the table shown in FIG. 6), the control unit 140 causes the audio device 330 to output the information as sound, and causes the display device 300 to blink the first notification information of the information. Furthermore, the control unit 140 causes the display device 300 to display, for example, information indicating the location of the display device 310 (for example, information on the position of the display device 310 or the name of the display device 310) as the first related information, and also causes the display devices 300, 310 to display the first notification information and the second notification information in the same color as the second related information.

[0123] Furthermore, for example, when the priority of information related to a predetermined event acquired by the acquisition unit 110 is medium (for example, priority "medium" in the table shown in FIG. 6), the control unit 140 causes the display device 300 to blink the first notification information of the information. Furthermore, the control unit 140 causes the display device 300 to display, as the first related information, information indicating the location of the display device 310 (for example, information on the position of the display device 310 or the name of the display device 310), and also causes the display devices 300, 310 to display the first notification information and the second notification information in the same color as the second related information.

[0124] In addition, for example, when the information relating to a specific event acquired by the acquisition unit 110 has a low priority (for example, priority "low" in the table shown in FIG. 6), the control unit 140 causes the display unit 300 to display information indicating the location of the display unit 310 (for example, information indicating the position of the display unit 310 or the name of the display unit 310) as the first related information, and also causes the display units 300, 310 to display the first notification information and the second notification information in the same color as the second related information.

[0125] Note that the information (priority information) indicating the relationship between the information about a predetermined event and the priority may be arbitrarily determined in advance and is not particularly limited.

[0126] Furthermore, the control unit 140 may change the display mode of the display device 300 so as to cause the display device 300 to display the second notification information and then to display the first notification information.

[0127] In addition, although the condition for determining the output mode is the priority in the above, the condition for determining the output mode is not particularly limited. For example, the condition for determining the output mode may be determined based on the complexity of the display information displayed on the display devices 300 to 320 (the number of pieces of information displayed, etc.). Alternatively, for example, the condition for determining the output mode may be arbitrarily determined by a user or the like. Alternatively, for example, the condition for determining the output mode may be determined based on the traveling state of the vehicle 10.

[0128] Also, for example, the output mode may be changed depending on the passage of time or whether or not the user has acknowledged the notification information.

[0129] Fig. 7A and Fig. 7B are diagrams showing a specific example of a display image 500 according to an embodiment. Specifically, Fig. 7A is a diagram showing an example of a display image including second notification information, and Fig. 7B is a diagram showing display image 500 after being changed from display image 500 shown in Fig. 7A to include first notification information.

[0130] For example, it is assumed that the acquisition unit 110 has acquired information regarding a predetermined event in which the target 20 has approached a predetermined distance from the travel route of the vehicle 10. In this case, for example, the control unit 140 controls the display device 300 to display notification information such as notification information 700 shown in Fig. 7A in a blinking manner, thereby causing the display device 300 to display the second notification information.

[0131] Next, the control unit 140 causes the display device 300 to display the notification information 660 without blinking as shown in FIG. 7B, thereby causing the display device 300 to display the first notification information.

[0132] Although not shown, when the control unit 140 causes the display device 300 to display the first notification information, the control unit 140 may cause the display device 310 to display the second notification information.

[0133] In this way, for example, when determination unit 130 determines that the amount of information in the first display information is equal to or greater than a predetermined threshold, control unit 140 causes display device 300 to display the second notification information, and when a predetermined condition is satisfied, causes display device 300 to display the first notification information instead of the second notification information, and also causes display device 310 to display the second notification information.

[0134] According to this, for information that needs to be notified to the user as a particular priority, details of that information are first notified to the user, and the amount of information is reduced according to specified conditions, so that more information can be conveyed to the user quickly while preventing a decrease in visibility of the information displayed on the display device 300.

[0135] The predetermined condition may be arbitrarily determined in advance and is not particularly limited. For example, the predetermined condition is satisfied when the control unit 140 acquires operation information indicating that the user has performed an operation based on the second notification information, or when a predetermined time has elapsed since the control unit 140 caused the display device 300 to display the second notification information.

[0136] The operation information is, for example, gaze information of the user. For example, when the detection device 200 detects that the user has directed his / her gaze to the second notification information displayed on the display device 300, the detection device 200 outputs information indicating the detection as operation information to the display control device 100. Alternatively, for example, the display system 400 may include an operation device such as a touch panel that accepts user operations. In this case, the control unit 140 may determine that a predetermined condition is satisfied when the control unit 140 acquires information indicating that the second notification information has been confirmed from the user via the operation device as operation information. Alternatively, for example, when the second notification information is information indicating that a pedestrian is approaching from the left front, when the user looks to the left front, in other words, when the detection device 200 detects that the user's gaze has been directed to the left front, the control unit 140 may acquire operation information indicating that the user has performed an operation based on the second notification information.

[0137] As described above, the operation based on the second notification information is, for example, an operation of confirming the second notification information by the user, or an operation according to the content indicated by the second notification information.

[0138] According to these, the information displayed on the display device 300 can be reduced at an appropriate timing.

[0139] The predetermined time may be arbitrarily determined in advance and is not particularly limited.

[0140] Furthermore, the control unit 140 may include a clock unit such as an RTC (Real Time Clock).

[0141] The storage unit 150 is a storage device that stores a control program executed by a processing unit included in the display control device 100, threshold information indicating a predetermined threshold, priority information indicating the priority of a predetermined event, information amount information indicating the correlation between the display mode of notification information and the information amount, etc. The storage unit 150 is realized by, for example, a flash memory, a HDD (Hard Disk Drive), etc.

[0142] The display control device 100 may be disposed in the vehicle 10 or outside the vehicle 10.

[0143] The audio device 330 is an audio device that outputs sound under the control of the control unit 140. The audio device 330 is realized by, for example, an amplifier and a speaker.

[0144] The sound output by the audio device 330 may be a sound indicating a predetermined character string (for example, a voice saying "A pedestrian is approaching" or "Please check the left front"), a mechanical sound, or a warning sound, and is not limited to this.

[0145] [Processing Procedure] FIG. 8 is a flowchart showing a processing procedure of the display control device 100 according to the embodiment.

[0146] First, the acquisition unit 110 acquires information about a predetermined event from the detection device 200 (S101).

[0147] Next, the determination unit 120 determines a display device (first display device) on which information related to the predetermined event acquired by the acquisition unit 110 is to be displayed (S102). For example, the determination unit 120 determines the first display device based on line-of-sight information. In this example, it is assumed that the determination unit 120 determines the display device 300 as the first display device.

[0148] Next, the determination unit 130 determines whether the amount of information of the first display information included in the first display image (display image 500) displayed by the first display device (display device 300) is equal to or larger than a predetermined threshold (S103).

[0149] When the determination unit 130 determines that the amount of information of the first display information included in the display image 500 displayed by the display device 300 is equal to or greater than a predetermined threshold (Yes in S103), the control unit 140 causes the display device 300 to display the first notification information, that is, the first notification information indicating simplified information indicating information related to a predetermined event in a simplified form, and the first display information (S104). For example, the control unit 140 causes the first notification information to be superimposed on the display image 500 displayed by the display device 300.

[0150] Next, the control unit 140 causes the second display device to display the second notification information, that is, the second notification information indicating detailed information indicating details of information related to the predetermined event (S105). In this example, it is assumed that in step S102, the determination unit 120 sets the priority order of the display devices 300 to 320 in the order of highest to lowest: display device 300, display device 310, and display device 320. For example, when the display device 310, which is the second display device, displays the display image 510, which is the second display image, the control unit 140 causes the second notification information to be superimposed on the display image 510 displayed by the display device 310.

[0151] On the other hand, when the determination unit 130 determines that the amount of information of the first display information included in the display image 500 displayed by the display device 300 is not equal to or greater than the predetermined threshold (No in S103), the control unit 140 causes the display device 300 to display the second notification information (S106). For example, the control unit 140 causes the second notification information to be superimposed on the display image 500 displayed by the display device 300.

[0152] [Effects, etc.] As described above, the display control device 100 according to the embodiment includes a determination unit 130 that determines whether the amount of information of the first display information displayed on the first display device (e.g., the display device 300) is equal to or greater than a predetermined threshold, and a control unit 140 that, when the determination unit 130 determines that the amount of information of the first display information is equal to or greater than the predetermined threshold, (i) causes the first display device to display first notification information and the first display information related to a predetermined event, and (ii) causes a second display device (e.g., the display device 310) different from the first display device to display second notification information related to the predetermined event, which includes the first notification information and has a larger amount of information than the first notification information. For example, when the determination unit 130 determines that the amount of information of the first display information is less than the predetermined threshold, the control unit 140 causes the first display device to display the second notification information.

[0153] In this way, when the display control device 100 determines that the amount of information displayed on the first display device becomes excessive and complicated, it causes the first display device to display a simple message (simple information). Furthermore, the display control device 100 uses a plurality of display devices to perform a coordinated display combining display of simple information and display of detailed information, thereby transmitting the information to the user without reducing the amount of information while ensuring visibility. Specifically, in a display device that displays a large amount of information, for example, when a predetermined event occurs, only simplified information is displayed when notifying the user of new information related to the predetermined event. Therefore, it is possible to notify the user of new information while preventing the amount of information displayed on the display device from becoming too large. In addition, by causing a display device that does not display a large amount of information to display details about the new information, the user can grasp the details of the new information at a desired timing. Therefore, according to the display control device according to one aspect of the present disclosure, it is possible to suppress a decrease in the visibility of information displayed on the display device and a decrease in the amount of information notified to the user.

[0154] Also, for example, the control unit 140 causes the display device to display related information indicating that the information being displayed on the display device is related.

[0155] For example, the display control device 100 displays the detailed display on a display device different from the display device that displayed the simplified display at the same timing as the timing of displaying the simplified information, and further indicates the relevance of the information by using a simple frame of the same color or the like. This allows the user to easily understand which display device among the multiple display devices the details of the simplified information are displayed on. If the application (device) that generated the information displayed on the display device is the same, it may be determined that there is a relevance, or if the type of information displayed on the display device is the same, it may be determined that there is a relevance. For example, the detection device 200 may attach type information (e.g., speed information and / or navigation information, etc.) indicating the type of the predetermined event to the information related to the predetermined event output to the display control device 100. The display control device 100 may determine whether or not each piece of information is related based on the type information.

[0156] Also, for example, the first display device and the second display device are arranged in the vehicle 10 (that is, the same vehicle). In this case, for example, the determination unit 130 sets a predetermined threshold value based on the traveling state of the vehicle 10.

[0157] For example, when the speed of the vehicle 10 is high, it is expected that the driver will have to pay more attention to driving compared to when the speed of the vehicle 10 is low, and therefore it is considered difficult to obtain information from the display device. Therefore, by appropriately setting the amount of information to be displayed on the first display device based on the traveling state of the vehicle 10, such as the speed of the vehicle 10 and whether the vehicle 10 is turning right or left, the user can more easily grasp the information displayed on the first display device.

[0158] Furthermore, for example, the control unit 140 may display the second notification information on the first display device, and then display the first notification information in place of the second notification information.

[0159] According to this, for information that needs to be notified to the user as a particular priority, details of that information are first notified to the user, and the amount of information is reduced over time, etc., making it possible to convey more information to the user quickly while preventing a decrease in visibility of the information displayed on the first display device.

[0160] In addition, these comprehensive or specific aspects may be realized by a system, a method, an integrated circuit, a computer program, or a non-transitory recording medium such as a computer-readable CD-ROM, or may be realized by any combination of the system, the method, the integrated circuit, the computer program, or the non-transitory recording medium.

[0161] For example, a display control method according to one embodiment of the present disclosure determines whether the amount of information of first display information displayed on a first display device is equal to or greater than a predetermined threshold (S103), and if it is determined that the amount of information of the first display information is equal to or greater than the predetermined threshold (Yes in S103), (i) displays first notification information and the first display information regarding a specified event on the first display device (S104), and (ii) displays second notification information regarding the specified event, which includes the first notification information and has a larger amount of information than the first notification information, on a second display device different from the first display device (S105).

[0162] Moreover, for example, a program according to one aspect of the present disclosure is a program for causing a computer to execute the above-described display control method.

[0163] According to these, the same effects as those of the display control device 100 can be achieved.

[0164] (Other embodiments) Although the display control device and the like according to one or more aspects have been described based on the above embodiment, the present disclosure is not limited to the above embodiment. As long as it does not deviate from the gist of the present disclosure, various modifications conceived by a person skilled in the art to the above embodiment may also be included within the scope of the present disclosure.

[0165] For example, in the above embodiment, the detection device 200 determines whether or not a predetermined event has occurred, but the display control device 100 may determine whether or not a predetermined event has occurred.
