Description

[Technical Field]

[0001] The present invention relates to a display control device that controls the display on a display device of one or more images corresponding to facilities in the vicinity of a vehicle that are linked to the coordinates of a specific point on a map. [Background technology]

[0002] For example, Patent Document 1 describes a technology relating to a map display system that increases the possibility of effectively making users aware of new facilities that are not included in map information.

[0003] According to the technology described in Patent Document 1, the map display system counts the number of times a new facility (or the information corresponding to it) is highlighted, and highlights the new facility if the number of times the new facility is highlighted is less than a threshold, and does not highlight the new facility if the number of times the new facility is highlighted is equal to or greater than the threshold. Therefore, because the facility is not highlighted more than the set threshold, it is possible to reduce the possibility that users (passengers viewing the display device and riding in the vehicle) will feel annoyed by frequently seeing the same new facility highlighted.

[0004] Furthermore, even if a certain amount of time has passed since the new facility appeared, the new facility will be highlighted as long as the number of highlighting attempts is less than the threshold, which reduces the possibility that users will not notice the existence of the new facility. Therefore, it is possible to increase the possibility that the new facility can be effectively made known to users. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-27159 A (see paragraph

[0007] ) Summary of the Invention [Problem to be solved by the invention]

[0006] However, according to the technology described in Patent Document 1, if a facility is frequently seen, the facility has a low priority, and even if it is not highlighted, it may be annoyed to the user. Furthermore, if the amount of information presented within the field of view in front of the vehicle is limited by regulations, it is possible that the facility will not be displayed within the user's field of view in the first place because information corresponding to a low-priority facility is presented. Furthermore, since the decision on whether to highlight a facility is based on the number of times it is highlighted, if the user has visited the facility that is the subject of highlighting, it may be highlighted even though there is no need for information corresponding to the facility, which may be annoyed to the user. Therefore, there is room for improvement.

[0007] Therefore, the present invention aims to provide a display control device, etc., that can reduce the annoyance caused to users by the frequent display of facilities that are already known to them, by changing the display mode of the facility depending on the number of times or frequency of display of the facility (or the display of information corresponding to the facility), or the number of times or frequency of visits by the user to the facility.

[0008] Other objects of the present invention will become apparent to those skilled in the art by referring to the following exemplary aspects and best modes, as well as the accompanying drawings. [Means for solving the problem]

[0009] In order to facilitate an understanding of the outline of the present invention, the following examples are given of embodiments according to the present invention.

[0010] In a first aspect according to the present invention, there is provided a display control device that controls the display on a display device of one or more images corresponding to facilities in the vicinity of a vehicle linked to the coordinates of a specific point on a map, the display control device comprising: a facility information acquisition unit that acquires facility information related to the surrounding facilities; an image generation unit that generates the image related to the acquired facility information; and a display control unit that, when displaying the image on the display device, stores display history information of the image and / or location history information related to the surrounding facilities, and controls the display mode of the image based on the stored display history information of the image and / or the location history information, and the display control unit controls to change the display mode of the image depending on the number of times or display frequency of the one or more images corresponding to the surrounding facilities, or the number of times or frequency of visits to the surrounding facilities.

[0011] In a first aspect, when the display control unit displays an image related to facility information about a surrounding facility acquired by the facility information acquisition unit on the display device, the display control unit stores display history information of the image and / or location history information about the surrounding facility, and controls the display mode of the image based on the stored display history information and / or location history information of the image. Specifically, the display mode of the image is controlled to change depending on the number of times or display frequency of one or more images corresponding to the surrounding facility, or the number of times or frequency of visits to the surrounding facility, thereby reducing the annoyance of the user of having information they already know displayed in the same way over and over again, and making it easier for the user to recognize new information.

[0012] Here, "facility information" refers to information about an object that is of interest or that attracts the attention of the viewer, the vehicle occupant, and includes, for example, location information indicating the location of a facility such as a public institution, station, road, commercial facility, leisure spot, etc., as well as additional information such as the facility's name, pronunciation, address, business hours, reviews, etc., and how crowded it is. Also, "one or more images corresponding to nearby facilities" or "images related to facility information" refers to, for example, images (POI: Point Of Interest display) of facilities with additional information PI-b, PI-c, etc., including an icon PI-a that represents an object based on the facility information, as shown in Figure 2.

[0013] Furthermore, "display history information" refers to data such as previously displayed POI displays and their timelines (chronological order), which are stored in a predetermined area of the storage unit 140 shown in FIG. 1, and can be referenced by the display control unit 130. "Location history information" refers to information about facilities used in the past, such as places visited by the user, routes to destinations, and timelines using these, which is stored in the navigation device 300 shown in FIG. 1, and can be acquired by the display control device 100 via the information acquisition unit 110. "Controlling the display mode of images" refers to changing the display mode of images depending on the number of times or frequency of display of one or more images (POI displays) corresponding to surrounding facilities, or the number of times or frequency of visits to surrounding facilities, and mainly refers to control to reduce the visibility of POI displays.

[0014] Furthermore, "the number of times one or more images corresponding to surrounding facilities have been displayed" refers to the total number of times images related to surrounding facilities (POI display) have been displayed in the past, and "display frequency" refers to the number of times images related to surrounding facilities (POI display) have been displayed in a certain period of time. Here, a threshold value is set for each, and the display mode of the POI display is controlled depending on whether the threshold value is above or below the threshold value. Also, "the number of visits to surrounding facilities" refers to the total number of times a user has visited surrounding facilities in the past, and "visit frequency" refers to the number of visits to surrounding facilities in a certain period of time. Here, a threshold value is set for each, and the display mode of the POI display is controlled depending on whether the threshold value is above or below the threshold value.

[0015] In a second aspect dependent on the first aspect, the display control unit may perform control to reduce the visibility of the image, erase the image, or reduce the amount of information displayed on the image, depending on the number of times or frequency of display of one or more of the images corresponding to the surrounding facilities, or the number of times or frequency of visits to the surrounding facilities.

[0016] In a second aspect, the display control unit controls the display of one or more images corresponding to nearby facilities to be reduced in visibility, erase the images, or reduce the amount of information displayed on the images, depending on the number of times or frequency of display of the images or the number of visits or frequency of the nearby facilities. Here, "control to reduce visibility" refers to controlling display attributes, such as reducing the brightness, contrast, saturation, etc., of the image, increasing transparency, or reducing the display size. Visibility may also be reduced by shortening the display time. For example, when using a display device (head-up display device) that continues to display POIs while nearby facilities are within the display field of view, the POI display area may be set to a smaller field of view than the display field of view, thereby shortening the display time and reducing visibility. Alternatively, the amount of information displayed may be reduced. For example, in the POI display format shown in Figure 4, PI-b and PI-c are not displayed, and only the icon portion indicated by PI-a is displayed. Alternatively, the POI display may be erased (not displayed) rather than reducing visibility.

[0017] In a third aspect dependent on the first aspect, the display control unit may perform control such that the amount of change when changing the display mode of the image increases the more times or frequency the image corresponding to the surrounding facility is displayed, or the more times or frequency the surrounding facility is visited.

[0018] In a third aspect, the display control unit performs control such that the amount of change in the display mode of the image (POI display) corresponding to the surrounding facility increases the more times or frequency the image (POI display) corresponding to the surrounding facility is displayed, or the more times or frequency the surrounding facility is visited. For example, by increasing the strength for reducing visibility (by emphasizing display attribute control such as reducing brightness, contrast, saturation, etc. when displaying an image, increasing transparency, or reducing the display size), visibility is further reduced, and POI displays that are annoying to users and that the user does not need to check become less noticeable, thereby further reducing the annoyance of users seeing information they already know displayed in the same way over and over again.

[0019] In a fourth aspect subordinate to the first aspect, the display control unit may determine the display priority for each image according to the number of times or frequency of display of one or more of the images corresponding to the surrounding facilities, or the number of visits or visit frequency of the surrounding facilities, and perform control to reduce the visibility, erase, or reduce the amount of information of the image with the lower determined display priority.

[0020] In the fourth aspect, the display control unit determines the display priority for each image according to the number of times or frequency of display of one or more images (POI displays) corresponding to the surrounding facilities, or the number of visits or visit frequency of the surrounding facilities, and performs control to reduce the visibility, erase, or reduce the amount of information of the image with the lower determined display priority. For example, as shown in FIG. 5A, taking a scene where a plurality of POI displays (PI-1, PI-2) are displayed as an example, if the determined display priority is PI-1 < PI-2, the display control unit performs a change in the display mode (mainly, a process of reducing visibility) on PI-1, which is the POI display with the lower display priority. Also, when three types of POI displays are simultaneously displayed (not shown), if the determined display priority is PI-1 < PI-2 < PI-3, control may be performed such that the amount of change in the display mode is 0% for PI-3, 50% for PI-2, and 100% for PI-1. Further, thresholds may be set to group them and determine their display priorities, such as group A (PI-1) < group B (PI-2 and PI-3), and a change in the display mode may be performed on the group with the lower display priority.

[0021] In a fifth aspect subordinate to the fourth aspect, the display control unit may set the display priority lower as the number of times or frequency of display of one or more of the images corresponding to the surrounding facilities is higher, or as the number of visits or visit frequency of the surrounding facilities is higher.

[0022] In the fifth aspect, the display control unit sets a lower display priority for one or more images (POI displays) corresponding to surrounding facilities the more times or frequently they are displayed, or the more times or frequently the surrounding facilities are visited, and controls the image (POI display) with the lower display priority to be less visible, erased, or have less information, thereby making the presentation of information (POI displays) that is already known to the user less noticeable, thereby reducing the likelihood of causing annoyance to the user.

[0023] In a sixth aspect according to the present invention, there is provided a head-up display device that allows a viewer to view one or more images corresponding to peripheral facilities located around the vehicle by superimposing them on a forward field of view on an imaging surface that is virtually set in front of the vehicle, the head-up display device comprising: an image display unit; an information acquisition unit that acquires facility information related to the peripheral facilities; an image generation unit that generates the image related to the acquired facility information; and a display control unit that, when displaying the generated image on the image display unit, stores display history information of the image and / or location history information related to the peripheral facilities, and controls the display mode of the image based on the stored display history information of the image and / or the location history information, and controls the display of the image on the image display unit by changing the display mode of the image depending on the number of times or display frequency of the one or more images corresponding to the peripheral facilities, or the number of times or frequency of visits to the peripheral facilities.

[0024] In a sixth aspect, when the display control unit displays an image relating to facility information about a surrounding facility acquired by the facility information acquisition unit on the image display unit, the display control unit stores POI display history information for the image and / or location history information for the surrounding facility, and controls the display mode of the image based on the stored POI display history information and / or location history information for the image. Specifically, the display control unit controls the image display unit to change the display mode of the image depending on the number of times or frequency of display of one or more images (POI display) corresponding to the surrounding facility, or the number of times or frequency of visits to the surrounding facility. This makes it possible to provide a head-up display device that reduces the annoyance of users having information they already know displayed repeatedly in the same way and makes it easier for users to recognize new information.

[0025] In addition, when a head-up display device performs control to change the display mode, it is possible to perform control to reduce visibility by shortening the display time, for example. For example, in a head-up display device that continues to display a POI corresponding to a nearby facility while the POI is within the display field of view, the POI display area can be set to a field of view range smaller than the display field of view, thereby shortening the display time and reducing visibility.

[0026] In a seventh aspect according to the present invention, there is provided a display control method for controlling the display on a display device of one or more images corresponding to facilities in the vicinity of a vehicle linked to the coordinates of a specific point on a map, the method comprising: a facility information acquisition step for acquiring facility information regarding the surrounding facilities; an image generation step for generating the image related to the acquired facility information; and a display control step for, when displaying the image on the display device, storing display history information of the image and / or location history information regarding the surrounding facilities, and controlling the display mode of the image based on the stored display history information of the image and / or the location history information, wherein the display control step comprises a sub-step for controlling the change of the display mode of the image according to the number of times or display frequency of the one or more images corresponding to the surrounding facilities, or the number of times or frequency of visits to the surrounding facilities.

[0027] In a seventh aspect, when an image related to acquired facility information about a peripheral facility is displayed on a display device, image display history information and / or location history information about the peripheral facility is stored, and the display mode of the image is controlled based on the stored image display history information and / or location history information. Specifically, the display mode of the image is controlled to change depending on the number of times or frequency of display of one or more images corresponding to the peripheral facility, or the number of times or frequency of visits to the peripheral facility, thereby providing a display control method that reduces the annoyance of users having information they already know displayed in the same way over and over again, and makes it easier for users to recognize new information.

[0028] In an eighth aspect according to the present invention, there is provided a program for a display control device that controls the display on a display device of one or more images corresponding to facilities in the vicinity of a vehicle linked to the coordinates of a specific point on a map, the program causing a processor of the display control device to execute an information acquisition process for acquiring facility information related to the surrounding facilities, an image generation process for generating the image related to the acquired facility information, and a display control process for storing display history information of the image and / or location history information related to the surrounding facilities when the image is displayed on the display device, and controlling the display mode of the image based on the stored display history information of the image and / or the location history information, and the display control process changes the display mode of the image depending on the number of times or display frequency of the one or more images corresponding to the surrounding facilities, or the number of times or frequency of visits to the surrounding facilities.

[0029] In an eighth aspect, when an image (POI display) relating to acquired facility information about a surrounding facility is displayed on a display device by a processor of the display control device reading and executing a program stored in an internal or external memory, the processor can store display history information of the POI display and / or location history information about the surrounding facility, and control the display mode of the POI display based on the stored image display history information and / or location history information. Specifically, the display mode of the image (POI display) corresponding to the surrounding facility is controlled to change depending on the number of times or display frequency of one or more images (POI display) corresponding to the surrounding facility, or the number of times or frequency of visits to the surrounding facility, thereby reducing the annoyance of the user of having information they already know displayed in the same way over and over again, and making it easier for the user to recognize new information.

[0030] In a ninth aspect according to the present invention, there is provided a vehicle display system comprising: a navigation device having facility information linked to the coordinates of specific points on a map; a head-up display device that displays one or more images corresponding to peripheral facilities located around the vehicle on an imaging surface virtually set in front of the vehicle, superimposed on the forward field of view, thereby allowing the viewer to view the images; and a display control device that controls the head-up display device, wherein the display control device comprises: a facility information acquisition unit that acquires facility information related to the peripheral facilities from the navigation device; an image generation unit that generates the images related to the acquired facility information; and a display control unit that, when displaying the images on the display device, stores display history information of the images and / or location history information related to the peripheral facilities, and controls the display mode of the images based on the stored display history information of the images and / or the location history information, and the display control unit changes the display mode of the images depending on the number of times or display frequency of the one or more images corresponding to the peripheral facilities, or the number of visits or frequency of visits to the peripheral facilities, and controls the display on the head-up display device.

[0031] In a ninth aspect, when a display control device acquires facility information about surrounding facilities from a navigation device and displays an image (POI display) corresponding to the acquired surrounding facilities on a display device, the display control device stores display history information about the POI display and / or location history information about the surrounding facilities, and controls the display mode of the POI display based on the stored display history information and / or location history information about the POI display. Specifically, the display mode of the POI display is changed and displayed on the head-up display device depending on the number of times or frequency of display of one or more images (POI displays) corresponding to the surrounding facilities, or the number of times or frequency of visits to the surrounding facilities. This makes it possible to provide a vehicle display system that reduces the annoyance of users having information they already know displayed in the same way over and over again, and makes it easier for users to recognize new information.

[0032] Those skilled in the art will easily understand that the exemplified embodiments according to the present invention can be further modified without departing from the spirit of the present invention. [Brief explanation of the drawings]

[Figure 6] 1 is a block diagram showing a configuration of a head-up display device according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0034] The best mode described below is used to facilitate understanding of the present invention, and therefore, those skilled in the art should be aware that the present invention is not unduly limited by the mode described below (hereinafter referred to as the present mode).

[0035] (Configuration of the embodiment) Fig. 1 is a block diagram showing an example of the system configuration of a vehicular display system 1000 according to this embodiment. As shown in Fig. 1, the vehicular display system 1000 according to this embodiment includes a display control device 100 according to this embodiment, a display device 200, a navigation device 300, and a communication unit 400.

[0036] The display control device 100 of this embodiment controls the display of facility information linked to the coordinates of a specific point on a map (POI location information 311, described later) on the display device 200, and is composed of an information acquisition unit 110, an image generation unit 120, a display control unit 130, and a memory unit 140, all of which are commonly connected via an internal bus 150.

[0037] The information acquisition unit 110 can acquire navigation information including map information 320 and facility information 310 (POI position information 311, POI incidental information 312) from the navigation device 300 connected via a CAN (Control Area Network) 500, and output the information to the display control unit 130. For this reason, the information acquisition unit 110 includes and is configured to include a facility information acquisition unit 111, a map information acquisition unit 112, and a location history information acquisition unit 113.

[0038] The facility information acquisition unit 111 can acquire facility information, such as POI position information 311 and POI incidental information 312, stored in the navigation device 300, and output the information to the display control unit 130. The navigation device 300 may acquire necessary facility information from a communication unit 400 capable of network communication, such as a smartphone. The map information acquisition unit 112 can acquire map information 320 stored in the navigation device 300 and output the information to the display control unit 130. The location history information acquisition unit 113 can acquire information on facilities used in the past from location history information 330 stored in the navigation device 300, such as data on facility visit histories by the user, routes to destinations, and timelines using these data, and output the information to the display control unit 130.

[0039] The storage unit 140 is implemented with static RAM, dynamic RAM, flash memory, or the like, and stores POI display history information 140a in part of its storage area. The POI display history information 140a is specifically the display history of POI displays (number of times displayed, display frequency, etc.), and this data is provided to the display control unit 130 as necessary.

[0040] The image generation unit 120 can generate an image (POI display) related to facility information based on facility information 310 (POI location information 311, POI additional information 312) acquired from the navigation device 300 via the information acquisition unit 110, and output it to the display control unit 130.

[0041] When displaying one or more images (POI display) corresponding to peripheral facilities on the display device 200, the display control unit 130 stores POI display history information of the images and / or location history information related to the peripheral facilities, and can control the display mode of the images (POI display) based on the stored POI display history information and / or location history information of the images. In this case, the display control unit 130 controls to change the display mode of the images (POI display) depending on the number of times or display frequency of one or more images (POI display) corresponding to peripheral facilities, or the number of visits or visit frequency of the peripheral facilities.

[0042] In addition, the display control unit 130 can control to reduce the visibility of one or more images (POI display) corresponding to surrounding facilities (POI display), erase the image (POI display), or reduce the amount of information displayed in the image (POI display), depending on the number of times or frequency of display of the image (POI display), or the number of times or frequency of visits to the surrounding facilities.

[0043] In addition, the display control unit 130 can perform control such that the greater the number of times or frequency of display of an image corresponding to a surrounding facility, or the greater the number of times or frequency of visits to the surrounding facility, the greater the amount of change when changing the display mode of the image (POI display).

[0044] In addition, the display control unit 130 can determine the display priority for each image depending on the number of times or frequency of display of one or more images (POI display) corresponding to surrounding facilities, or the number of times or frequency of visits to the surrounding facilities, and can control the image (POI display) with the lower determined display priority to be either reduced in visibility, erased, or have less information.

[0045] Furthermore, the display control unit 130 can set a lower display priority as the number of times or frequency of display of one or more images (POI display) corresponding to the surrounding facilities increases, or as the number of times or frequency of visits to the surrounding facilities increases.

[0046] The display device 200 is, for example, a head-up display device (HUD device 200A) housed in the dashboard of the vehicle, which displays a virtual image (here, a POI display) superimposed on the foreground on an imaging plane (a display area; see the display field angle HD in FIG. 2 described later) virtually set in front of the vehicle. The HUD device 200A projects a virtual image onto the windshield, which is a projection target member of the vehicle, and allows the occupant to view the virtual image at a predetermined distance from the occupant. The display device 200 is not limited to the HUD device 200A, but may also be a center information display (CID) provided in the center of the vehicle or a head-mounted display device (HMD device) mounted on the occupant's head.

[0047] The navigation device 300 has map information 320, and this map information 320 can acquire the latest map information and update the map database by communicating with an external center (not shown) via, for example, a V2X (Vehicle to X) type communication system (communication unit 400). Here, the map information stored in the map database is mapping data that has been digitized to represent the vehicle's driving environment. As the mapping data, it is preferable that it be digital data of a particularly high-precision dynamic map. Here, a "dynamic map" is a digital map that combines a huge amount of dynamic information that changes every moment, such as traffic regulations, construction information, accidents, congestion, pedestrians, and traffic lights, with static information such as high-precision three-dimensional position information (road surface information, slope information, three-dimensional structures).

[0048] (Operation of the embodiment) FIG. 2 is a diagram showing an example of a screen configuration displayed on the display device 200 by the display control device 100 according to this embodiment. Here, a HUD device 200A is used as the display device 200, and four POI displays (PI) are displayed within the display angle of view (HD) of the HUD device 200A. Also, FIG. 3A is a flowchart showing the operation procedure of Example 1 (determination using a threshold value) of the display control device 100 according to this embodiment, and FIG. 4 is a diagram showing an example of an image (POI display format) related to facility information generated by the display control device 100 according to this embodiment. Here, the operation of Example 1 will first be described with reference to FIGS. 2, 3B, and 4.

[0049] 3A, in the display control device 100 of the first embodiment (determination based on a threshold), the information acquisition unit 110 first acquires nearby facility information (see step ST11). The nearby facility information is acquired, for example, from a navigation tool such as a navigation device 300 installed in a vehicle or a navigation app on a smartphone. Here, the nearby facility information includes typical information displayed on the navigation device 300 or a navigation app, such as the name and business hours of the facility, category, brief description of the facility, menu list, rating, and reviews.

[0050] Next, the display control unit 130 refers to the location history information 330 acquired from the navigation device 300 or the like via the location history information acquisition unit 113, and checks the number and frequency of visits to the surrounding facilities (see step ST12). The location history information 330 stores data such as visited places, routes to destinations, and timelines using these, and the display control unit 130 can acquire information on facilities used in the past. Next, the display control unit 130 determines whether the number of visits to the surrounding facilities is equal to or greater than a threshold (see step ST13). If the number is equal to or greater than the threshold (see step ST13 "YES"), the display control unit 130 controls to change the display mode of the POI display (see step ST16). If the number is less than the threshold (see step ST13 "NO"), the display control unit 130 refers to the POI display history information 140a stored in the storage unit 140 (see step ST14).

[0051] The threshold value set at this time may be the frequency of visits instead of the number of visits. Here, the number of visits is the total number of times the user has visited the corresponding surrounding facility in the past, and the frequency of visits is the number of times the user has visited the corresponding surrounding facility within a certain period of time. The threshold value may be set by default or dynamically by the display control unit 130, such as "three visits" or "one visit per week."

[0052] In step ST14, the display control unit 130 can check the number of times and frequency of display of POI displays related to nearby facilities by referring to the POI display usage history information 140a stored in a predetermined area of the storage unit 140. Note that the POI display usage history information 140a stores data on POI displays that have been displayed in the past and their timelines, and the display control unit 130 can acquire information on POI displays that have been used in the past by referring to the POI display usage history information 140a.

[0053] Next, the display control unit 130 determines whether the number of times the POI of the surrounding facility is displayed is equal to or greater than a threshold (see step ST15). If the number is equal to or greater than the threshold (see step ST15 "YES"), the display control unit 130 performs control to change the display mode of the POI display (see step ST16). If the number is less than the threshold (see step ST15 "NO"), the image generation unit 120 generates an image (POI display) related to the facility information (see step ST18). The display control unit 130 acquires the image generated by the image generation unit 120 in synchronization with the display timing, thereby enabling the POI display, for example, as shown in an example in FIG. 2 (see step ST18).

[0054] The threshold value set at this time may be the POI display frequency instead of the POI display count. The POI display count is the total number of times that POIs related to nearby facilities have been displayed in the past, and the POI display frequency is the number of times that nearby facilities have been displayed within a certain period of time. The threshold value may be set by default or dynamically by the display control unit 130, such as "POI display count 3 times" or "POI display frequency 1 time / week."

[0055] In step ST16, the display control unit 130 performs a process to change the display mode of the POI display related to the surrounding facilities. The change in the display mode is mainly a process for reducing visibility. Possible methods for reducing visibility include controlling display attributes such as reducing the brightness, contrast, and saturation of the display, increasing transparency, and reducing the display size. Another possible method is to reduce visibility by shortening the display time. For example, in the case of a display system that continues to display POIs while surrounding facilities are within the display angle of view (see HD in FIG. 2) (the so-called HUD device 200A), a POI display area can be set to a range of angle of view smaller than the display angle of view HD, thereby reducing the display time and thereby reducing visibility.

[0056] Another possible method for changing the display mode of the POI display is to reduce the amount of information displayed. As described above, the image related to facility information (POI display) is, for example, an image of incidental information PI-b, PI-c, etc. of the facility including an icon PI-a that is expressed in the shape of an object based on the facility information, as shown in an example of the display mode in FIG. 4. Here, the display control unit 130 can reduce the amount of information displayed by displaying only the PI-a portion without displaying PI-b and PI-c. Also, instead of performing a process to reduce visibility, a method of not displaying the icon (display erasure process) may be used.

[0057] As described above, according to the display control device 100 of the first embodiment, when the display control unit 130 displays an image (POI display) related to facility information about a peripheral facility acquired by the facility information acquisition unit 111 on the display device 200, the display control unit 130 stores the POI display history information 140a of the image and / or the location history information 330 related to the peripheral facility, and controls the display mode of the image (POI display) based on the stored POI display history information 140a of the image and / or the location history information 330. Specifically, the display control unit 130 controls to change the display mode of one or more images (POI display) corresponding to the peripheral facility in accordance with the number of times or display frequency of the images (POI display) or the number of times or frequency of visits to the peripheral facility, thereby reducing the annoyance to the user of having information they already know displayed in the same way over and over again and enabling the user to easily recognize new information.

[0058] Furthermore, the display control unit 130 can control the visibility of one or more images (POI displays) corresponding to nearby facilities based on the number of times or frequency of display of the images, or the number of visits or frequency of visits to the nearby facilities, thereby reducing the visibility of POI displays that do not require repeated viewing by the user. As a result, the annoyance of users seeing information they already know displayed repeatedly can be further reduced. The same effect can be achieved by erasing the images (POI displays) or reducing the amount of information displayed in the images (POI displays). For example, the display control unit 130 can control the display attributes of the POI displays, such as reducing brightness, contrast, saturation, etc., increasing transparency, or reducing the display size. Alternatively, visibility can be reduced by shortening the display time.

[0059] For example, when using a display device (HUD device 200A) that continues to display POIs while surrounding facilities are within the display field of view HD (see FIG. 2), the POI display area can be set to a field of view range smaller than the display field of view HD, thereby shortening the display time and reducing visibility. Alternatively, the same effect can be achieved by controlling the amount of information displayed to be reduced.

[0060] Fig. 3B is a flowchart showing the operation procedure of the display control device 100 of the second embodiment (determination based on display priority). Fig. 5A is a diagram showing an example of POI display (PI-1, PI-2) of the second embodiment, Fig. 5B is a diagram showing an example of POI display when the display mode of the POI display (PI-1) is changed (transparency reduction processing), Fig. 5C is a diagram showing an example of POI display when the display mode of the POI display (PI-1) is changed (size reduction processing), and Fig. 5D is a diagram showing an example of POI display when the display mode of the POI display (PI-1) is changed (display erasure processing). The operation of the second embodiment will be described below with reference to Figs. 3B and 5A to 5D.

[0061] 3B, in the display control device 100 of the second embodiment, first, the information acquisition unit 110 acquires nearby facility information (see step ST21). The nearby facility information is acquired, for example, from a navigation tool such as a navigation device 300 installed in a vehicle or a navigation app on a smartphone. Here, the nearby facility information includes typical information displayed on the navigation device 300 or a navigation app, such as the name and business hours of the facility, category, brief description of the facility, menu list, rating, and reviews.

[0062] Next, the display control unit 130 determines whether there are multiple POI displays to be displayed (see step ST22). If there are multiple POI displays to be displayed (see "YES" in step ST22), the display control unit 130 refers to the location history information 330 acquired from the navigation device 300 via the location history information acquisition unit 113 (see step ST23) to check the number of visits and frequency of surrounding facilities. The location history information 330 stores data such as places visited by the user, routes to destinations, and timelines using these locations. By referring to this location history information 330, the display control unit 130 can check information about facilities used in the past (the number of visits and frequency of visits to surrounding facilities). If there are not multiple POI displays to be displayed (see "NO" in step ST22), the process proceeds to step ST29.

[0063] The display control unit 130 refers to the location history information 330 (see step ST23), and then determines whether there is a difference in the number of visits to the surrounding facilities (see step ST24). If it is determined that there is no difference (step ST24 "NO"), the process proceeds to step S25. If it is determined that there is a difference (step ST24 "YES"), the process proceeds to step S27. In step S25, the display control unit 130 can check the number of times and frequency of display of POI displays related to surrounding facilities by referring to the POI display usage history information 140a stored in a predetermined area of the storage unit 140. The POI display usage history information 140a stores data on POI displays that have been displayed in the past and their timelines, and the display control unit 130 can obtain information on POI displays that have been used in the past.

[0064] Subsequently, the display control unit 130 determines whether there is a difference in the number of times of displaying the POI display related to the surrounding facilities (see step ST26). Here, if it is determined that there is no difference (step ST26 "NO"), the process proceeds to the process of step S29, and if it is determined that there is a difference (see step ST26 "YES"), the process proceeds to the process of step S27. In step S27, the display priority of the POI display is determined. For example, as shown in an example in FIG. 5A, assume a scene where a plurality of POI displays (PI-1, PI-2) are displayed. Here, prior to executing the process of step ST26, the display priority has been determined for each of the plurality of POI displays to be displayed. If, for example, the display priority is PI-1 < PI-2, the display control unit 130 changes the display mode for PI-1, which is the POI display with the lower display priority (step ST28).

[0065] Also, when three types of POI displays are displayed simultaneously, for example, if the display priority is determined as PI-1 < PI-2 < PI-3, the display control unit 130 can also implement it in such a form that in step ST28, a 50% change in the display mode is made for PI-2 and a 100% change in the display mode is made for PI-1. Further, by setting a threshold value and performing grouping, such as group A (PI-1) < group B (PI-2 and PI-3), to determine their display priorities, a change in the display mode may be implemented for the group with the lower priority (see step ST28).

[0066] As described above, in step S28, the display mode of the POI display related to the surrounding facilities is changed. This change in display mode is primarily a process for reducing visibility. A method for reducing visibility may be similar to that of Example 1 (step ST16 in FIG. 3A). For example, when reducing visibility by increasing the transparency of the POI display, a transparency reduction process is performed on the POI display PI-1, as shown in FIG. 5B. Furthermore, when reducing visibility by reducing the POI display, a size reduction process is performed on the POI display PI-1, as shown in FIG. 5C. Alternatively, it may be possible to not display the POI display PI-1 (display erasure process), as shown in FIG. 5D.

[0067] If it is determined in step ST26 that there is no difference in the number of times the POI is displayed (step ST26 "NO"), the image generation unit 120 generates a POI display (see step ST29), and the display control unit 130 acquires the POI display generated by the image generation unit 120 in synchronization with the display timing, thereby displaying it on the display device 200 (within the display angle of view HD of the HUD device 200A) (see step ST30).

[0068] According to the above-described Example 2, the display control unit 130 determines the display priority for each image according to the number of times or frequency of display of one or more images (POI display) corresponding to the surrounding facilities, or the number of visits or visit frequency of the surrounding facilities, and performs control to reduce the visibility, erase, or reduce the amount of information of the image with the lower determined display priority. For example, as shown in FIG. 5A, assuming a scene in which a plurality of POI displays (PI-1, PI-2) are displayed, if the determined display priority is PI-1 < PI-2, the display control unit 130 changes the display mode for the POI display PI-1 with the lower display priority. Also, when three types of POI displays are displayed simultaneously, if the determined display priority is PI-1 < PI-2 < PI-3, control can be performed to implement 0% for PI-3, 50% for PI-2, and 100% for PI-1 with respect to the amount of change in the display mode. Also, threshold values may be set to group them and determine their display priorities, such as Group A (PI-1) < Group B (PI-2 and PI-3), and the display mode may be changed for the group with the lower priority.

[0069] Further, the display control unit 130 sets the display priority lower as the number of times or frequency of display of one or more images (POI display) corresponding to the surrounding facilities is higher, or as the number of visits or visit frequency of the surrounding facilities is higher, and performs control to reduce the visibility, erase, or reduce the amount of information of the image (POI display) with the lower set display priority, so that known information presentation (POI display) that is repeatedly visible to the user becomes less conspicuous, and the possibility of giving annoyance to the user can be reduced accordingly.

[0070] Furthermore, the display control unit 130 performs control such that the amount of change when changing the display mode of the image (POI display) corresponding to the surrounding facility increases the more times or frequency the image (POI display) corresponding to the surrounding facility is displayed, or the more times or frequency the surrounding facility is visited. For example, by increasing the strength for reducing visibility (by emphasizing display attribute control such as reducing brightness, contrast, saturation, etc. when displaying an image, increasing transparency, or reducing the display size), visibility is further reduced, making unnecessary POI displays less noticeable, and further reducing the annoyance for users of seeing familiar information displayed in the same way over and over again.

[0071] (Variation) According to the display control device 100 of the above-described embodiment (Example 1 and Example 2), the display control device 100 has been described as controlling the change of the display mode of one or more images (POI display) corresponding to surrounding facilities in accordance with the number of times or display frequency of the images (POI display), or the number of times or frequency of visits to the surrounding facilities. However, for example, the HUD device 200A may incorporate the functions of the information acquisition unit 110, image generation unit 120, and display control unit 130 of the display control device 100, so that the HUD device 200A alone controls the change of the display mode of one or more images (POI display) corresponding to surrounding facilities in accordance with the number of times or display frequency of the images (POI display), or the number of times or frequency of visits to the surrounding facilities.

[0072] 6, the HUD device 200A of the present embodiment includes, for example, an information acquisition unit 201, an image generation unit 202, a display control unit 203, a storage unit 204, and an image display unit 205. The image generation unit 202 generates an image relating to facility information linked to the coordinates of a specific point on a map acquired from an external device such as a navigation device 400 via the information acquisition unit 201, and the display control unit 203 controls to change the display mode of the image according to the number of times or frequency of display of one or more images corresponding to surrounding facilities or the number of times or frequency of visits to the surrounding facilities.

[0073] The image display unit 205 is mainly composed of a light source 205a consisting of a light-emitting diode mounted on a wiring board, and a TFT (Thin Film Transistor Liquid Crystal) type liquid crystal display element 205b located on the emission side (directly above) of the light source 205a so as to transmit illumination light from the light source 205a to form display light, and the liquid crystal display element 205b outputs display light including a desired image by transmitting light emitted from the light source 205a. The liquid crystal display element 205b is a display device that forms a desired image including facility information based on display image data (drive signals) generated by drawing calculations by the display control unit 203, and displays the facility information superimposed on the foreground on an imaging plane (display area) virtually set in front of the vehicle, allowing the viewer, or occupant, to view it.

[0074] According to the HUD device 200A of this embodiment, when the display control unit 203 displays an image (POI display) related to facility information about a nearby facility acquired by the information acquisition unit 201 on the image display unit 205, the display control unit 203 stores POI display history information about the image and / or location history information about the nearby facility (both of which are stored in a predetermined area of the storage unit 204 or acquired from an external device such as a navigation device), and controls the display mode of the image (POI display) based on the stored POI display history information and / or location history information about the image. Specifically, the display mode of the image (POI display) is changed and displayed on the image display unit 205 according to the number of times or frequency of display of one or more images (POI display) corresponding to the nearby facility or the number of times or frequency of visits to the nearby facility. This makes it possible to provide the HUD device 200A that reduces the annoyance of the user of seeing information they already know displayed in the same way over and over again and allows the user to easily recognize new information.

[0075] Furthermore, the HUD device 200A of this embodiment provides Augmented Reality (AR) that captures the scenery in the field of view ahead of the vehicle using a camera or the like and displays navigation information including POI display superimposed on the actual image obtained by capturing the image, thereby reducing the possibility that the user will not notice the existence of the facility and increasing the possibility that the user will be effectively made aware of the facility.

[0076] Also, for example, as shown in FIG. 1, the HUD device 200A may be regarded as a simple display device 200, and the display control device 100 may acquire facility information from the navigation device 300, generate an image relating to the facility information, and perform control to change the display mode of one or more images (POI display) corresponding to the surrounding facilities according to the number of times or frequency of display of the images, or the number of times or frequency of visits to the surrounding facilities, and display the images on the HUD device 300A.

[0077] (Effects of the embodiment) As described above, the display control device 100 of this embodiment is a display control device 100 that controls the display of one or more images (for example, see the POI display (PI) in Figure 2) corresponding to facilities around a vehicle that are linked to the coordinates of a specific point on a map (POI location information 311) on the display device 200, as shown in Figure 1. The display control device 100 includes a facility information acquisition unit 111 that acquires facility information related to surrounding facilities, an image generation unit 120 that generates an image (POI display) related to the acquired facility information, and a display control unit 130 that, when displaying the image (POI display) on the display device 200, stores POI display history information 140a of the image and / or location history information 330 related to the surrounding facilities, and controls the display mode of the image (POI display) based on the stored POI display history information 140a and / or location history information 330 of the image, and the display control unit 130 controls changing the display mode of the image (POI display) depending on the number of times or display frequency of one or more images (POI display) corresponding to the surrounding facilities, or the number of times or frequency of visits to the surrounding facilities.

[0078] According to the display control device 100 of this embodiment, when the display control unit 130 displays an image (POI display) related to facility information about a nearby facility acquired by the facility information acquisition unit 111 on the display device 200, the display control unit 130 stores POI display history information 140a for the image and / or location history information 330 related to the nearby facility, and controls the display mode of the image (POI display) based on the stored POI display history information 140a and / or location history information 330 for the image. Specifically, the display control unit 130 controls changing the display mode of one or more images (POI display) corresponding to the nearby facility in accordance with the number of times or frequency of display of the image or the number of times or frequency of visits to the nearby facility. In this way, by changing the display mode of the facility (e.g., reducing visibility) in accordance with the number of times or frequency of display of the facility (information presentation corresponding to the facility) or the number of times or frequency of visits to the facility by the user, it is possible to reduce the annoyance caused to the user by the frequent display of a facility that is already known to the user.

[0079] Furthermore, according to the display control device 100 of this embodiment, the display control unit 130 controls the display of one or more images (POI displays) corresponding to nearby facilities, such as a POI display, to reduce the visibility of the images, erase the images, or reduce the amount of information displayed on the images, depending on the number of times or frequency of display of the images or the number of visits or frequency of the nearby facilities. Therefore, by changing the display mode of the POI display if the number of times or frequency of display or the number of visits or frequency of the nearby facilities is equal to or greater than a threshold, the possibility that the user will be annoyed by frequently seeing the same image (POI display) can be reduced. Furthermore, even after a certain period of time has passed since the POI display was first viewed, if the number of times or frequency of display or the number of visits or frequency of the nearby facilities is less than a threshold, the POI display continues to be displayed without changing its display mode, thereby reducing the possibility that the user will not notice the existence of the facility, and thus enabling the user to effectively recognize the facility.

[0080] Here, "control to reduce visibility" refers to controlling display attributes, such as reducing brightness, contrast, saturation, etc., when displaying an image, increasing transparency, or reducing the display size. Visibility may also be reduced by shortening the display time. For example, when using a display device 200 (HUD device 200A) that continues to display POIs while surrounding facilities are within the display field of view, the POI display area may be set to a field of view range smaller than the display field of view HD (see FIG. 2), thereby shortening the display time and thereby reducing visibility. Alternatively, control may be performed to reduce the amount of information displayed. For example, in the POI display format shown in FIG. 4, PI-b and PI-c, which are POI incidental information 312, are not displayed, and only the icon portion indicated by PI-a is displayed. Alternatively, a method of erasing (not displaying) the POI display may be considered, rather than performing a visibility reduction process.

[0081] Furthermore, according to the display control device 100 of this embodiment, the display control unit 130 performs control such that the amount of change when changing the display mode of an image corresponding to a peripheral facility (POI display) increases the more times or frequency the image corresponding to the peripheral facility is displayed, or the more times or frequency the peripheral facility is visited. For example, by increasing the strength for reducing visibility (by emphasizing display attribute control such as reducing brightness, contrast, saturation, etc. when displaying an image, increasing transparency, or reducing the display size), visibility is further reduced, making unnecessary POI displays less noticeable, and further reducing the annoyance that users experience when familiar information is displayed in the same way over and over again.

[0082] Also, according to the display control device 100 of the present embodiment, the display control unit 130 determines the display priority for each image according to the number of display times or display frequency of one or more images (POI display) corresponding to surrounding facilities, or the number of visits or visit frequency of surrounding facilities, and performs control to reduce the visibility, erase, or reduce the information amount of the image with the lower determined display priority. For example, as shown in FIG. 5A, in the case of exemplifying a scene where a plurality of POI displays (PI-1, PI-2) are displayed, if the determined display priority is PI-1 < PI-2, the display control unit changes the display mode of the POI display PI-1 with the lower display priority. Therefore, when there are a plurality of POI displays, it is possible to control the change of the display mode of the POI display selected according to the set display priority, and flexibly change the display mode of the facility (information presentation corresponding thereto) according to the number of display times or display frequency of the facility, or the number of visits or visit frequency of the user to the facility. Thus, it is possible to reduce the annoyance caused by the frequent display of facilities known to the user.

[0083] Also, according to the display control device 100 of the present embodiment, the display control unit 130 sets the display priority lower as the number of display times or display frequency of one or more images (POI display) corresponding to surrounding facilities is higher, or as the number of visits or visit frequency of surrounding facilities is higher. By performing control to reduce the visibility, erase, or reduce the information amount of the image (POI display) with the lower set display priority, the information presentation (POI display) known to the user becomes less prominent, and the possibility of giving annoyance to the user can be reduced accordingly.

[0084] The head-up display device of this embodiment is, for example, a HUD device 200A that, as shown in FIG. 2, allows a viewer to view one or more images corresponding to surrounding facilities located around the vehicle by superimposing them on the forward field of view on an imaging plane (display area, display angle of view HD in FIG. 2) that is virtually set in front of the vehicle. 6, the HUD device 200A includes an image display unit 205, an information acquisition unit 201 that acquires facility information related to surrounding facilities, an image generation unit 202 that generates an image (POI display) related to the acquired facility information, and a display control unit 203 that, when displaying the generated image (POI display) on the image display unit 205, stores POI display history information of the image and / or location history information related to the surrounding facilities (stored in a predetermined area of the storage unit 204) and controls the display mode of the image (POI display) based on the stored POI display history information and / or location history information of the image, and the display control unit 203 controls the display of one or more images (POI display) on the image display unit 205 by changing the display mode of the image (POI display) depending on the number of times or display frequency of one or more images (POI display) corresponding to the surrounding facilities or the number of times or frequency of visits to the surrounding facilities.

[0085] According to the HUD device 200A of this embodiment, when the display control unit 203 displays an image (POI display) related to facility information about a nearby facility acquired by the information acquisition unit 201 on the image display unit 205, the display control unit 203 stores POI display history information about the image and / or location history information about the nearby facility (both of which are stored in a predetermined area of the storage unit 204 or acquired from an external source such as the navigation device 300), and controls the display mode of the image (POI display) based on the stored POI display history information and / or location history information about the image. Specifically, the display mode of the image (POI display) is changed and displayed on the image display unit 205 according to the number of times or frequency of display of one or more images (POI display) corresponding to the nearby facility or the number of times or frequency of visits to the nearby facility. This makes it possible to provide the HUD device 200A that reduces the annoyance of the user of seeing information they already know displayed in the same way over and over again and allows the user to easily recognize new information.

[0086] Furthermore, the HUD device 200A of this embodiment provides augmented reality (AR) that captures the scenery in the forward field of view of the vehicle using a camera or the like and displays navigation information including POIs superimposed on the captured image. This reduces the possibility that the user will not notice the presence of facilities and increases the possibility that the user will be able to effectively recognize them. When controlling the HUD device 200A of this embodiment to change the display mode, for example, the HUD device 200A can perform control to reduce visibility by shortening the display time. For example, in a head-up display device that continues to display a POI corresponding to a nearby facility while the POI is within the display angle of view, the POI display area can be set to a smaller angle of view than the display angle of view, thereby shortening the display time and reducing visibility.

[0087] 1, the display control method of this embodiment is a display control method for controlling the display of one or more images (POI display) corresponding to facilities in the vicinity of a vehicle linked to coordinates of a specific point on a map on the display device 200. As shown in FIG. 3A, the display control method includes a facility information acquisition step (see ST11) for acquiring facility information related to the surrounding facilities, an image generation step (see ST17) for generating an image (POI display) related to the acquired facility information, and a display control step (see ST12, ST14, and ST16) for storing POI display history information of the image and / or location history information related to the surrounding facilities and controlling the display mode of the image (POI display) based on the stored POI display history information and / or location history information of the image, when the image (POI display) is to be displayed on the display device 200. The display control step includes substeps (see ST13, ST15, and ST16) for controlling the display mode of the image according to the number of times or frequency of display of one or more images corresponding to the surrounding facilities or the number of times or frequency of visits to the surrounding facilities.

[0088] According to the display control method of this embodiment, when an image related to acquired facility information about a peripheral facility is displayed on a display device, POI display history information for the image and / or location history information for the peripheral facility are stored, and the display mode of the image (POI display) is controlled based on the stored POI display history information and / or location history information for the image. Specifically, the display mode of one or more images (POI display) corresponding to the peripheral facility is controlled to change depending on the number of times or frequency of display of the image or the number of times or frequency of visits to the peripheral facility, thereby providing a display control method that reduces the annoyance of users having information they already know displayed repeatedly in the same way and makes it easier for users to recognize new information.

[0089] The program of this embodiment is, for example, a program of a display control device 100 that controls the display of one or more images (POI display) corresponding to facilities around the vehicle that are linked to the coordinates of a specific point on a map on a display device 200, as shown in Figure 1. The program then causes the processor of the display control device 100 to execute, for example, as shown in FIG. 3A, an information acquisition process (see step ST11) for acquiring facility information related to surrounding facilities, an image generation process (see step ST17) for generating an image (POI display) related to the acquired facility information, and a display control process (steps ST12, ST14, ST12, ST16) for storing POI display history information of the image and / or location history information related to the surrounding facilities when the image (POI display) is displayed on the display device 200, and controlling the display mode of the image (POI image) based on the stored POI display history information and / or location history information of the image, and in the display control process, the display mode of the image (POI display) is changed depending on the number of times or frequency of display of one or more images (POI display) corresponding to the surrounding facilities, or the number of times or frequency of visits to the surrounding facilities (see steps ST13, ST15, ST16).

[0090] According to the program of this embodiment, the processor of the display control device 100 reads and executes the program stored in an internal or external memory, so that when an image (POI display) related to acquired facility information about a nearby facility is displayed on the display device 200, the processor stores display history information of the POI display and / or location history information about the nearby facility, and can control the display mode of the POI display based on the stored POI display history information and / or location history information of the image. Specifically, the display mode of the image (POI display) corresponding to the nearby facility is controlled according to the number of times or frequency of display of one or more images (POI display) corresponding to the nearby facility, or the number of times or frequency of visits to the nearby facility. This reduces the annoyance of the user of having information they already know displayed in the same way over and over again, and makes it easier for the user to recognize new information.

[0091] In the display control device 100 of this embodiment, the functions executed by the display control device 100 are realized by the above-mentioned program executed by a computer. In this case, the display control unit 130 of the display control device 100 includes, as hardware for executing the above-mentioned program, a computer including, for example, a processor and at least one storage device (e.g., RAM). Also, at least some of the above-mentioned functions can be realized by a logic circuit. For example, an integrated circuit in which a logic circuit is formed is also included in the scope of the present invention.

[0092] The vehicular display system of this embodiment is a vehicular display system 1000 that includes, for example, a navigation device 300 having facility information linked to the coordinates of specific points on a map, a head-up display device (200 (HUD device 200A)) that displays one or more images (POI display) corresponding to surrounding facilities located around the vehicle on an imaging surface virtually set in front of the vehicle, superimposed on the forward field of view, thereby allowing the viewer to view the images, as shown in FIG. 1, and a display control device 100 that controls the HUD device 200A.
