The person information that can be displayed includes the number of people in the video, the location of each person, and the person's The details of the person determination method can be determined by using publicly known techniques. can.

[0034] The location attribute determination unit 255 determines the location information of the vehicle acquired by the travel information acquisition unit 22 and the above-mentioned D The location attributes of the current location of the vehicle are derived using the map information stored in B23. The system identifies the vehicle's location in the map information and determines the location attributes of that location. By identifying whether the location is correct, the location attribute information is derived.

[0035] The display control unit 256 receives the vehicle speed information acquired by the traveling information acquisition unit 22, the image determination unit 25 4, or the current position of the vehicle derived by the position attribute determination unit 255. The appropriate advertisement data is selected from the advertisement data stored in the DB 23 using at least one of the location attributes. The advertisement is selected and displayed on the advertisement display device 12. This process will be described in detail later. In addition, the display control unit 256 controls the advertisement information to be displayed on the advertisement display device 12 and the The display time is stored as a log in DB23.

[0036] FIG. 2 is a table showing an example of advertisement information of displayable advertisement data stored in DB 23. In Fig. 2, the labels indicating advertisements are A1 to A3, B1, C1, C2, and D. 1, D2 are shown, and the characteristic information includes the degree of movement of the advertisement, the target person attributes, and the position The advertisements A1 to A3 are all about the same office product A. Advertisement B1 is an advertisement about company B. Advertisements C1 and C2 are both advertisements about company A. Also, stores (e.g., supermarkets, shops) located near residential areas C in a specific area (including shopping centers, pharmacies, and / or restaurants) Advertisements D1 and D2 are advertisements for the same liquor D.

[0037] The characteristics information is as follows: "Advertisement activity" is the activity of each advertisement. This indicates the period or percentage during which a still image is displayed. In Figure 2, there are three options: "low," "medium," and "high." There are three levels: "Low", "Medium" and "High". In this example, if the "Ad Activity" is "Low", the ad will It is a still image, which means that there is no movement in the ad display. If the ad is made up of multiple still images, the still images are displayed in 1 to several seconds intervals. If the "Ad Motion Level" is "High", the ad will be switched to a video. This means that the ad is always moving.

[0038] In addition, the "person attributes" of the characteristic information indicates the attributes of the person who is the target of the advertisement. There are four types: "For office workers," "For housewives / househusbands," and "For adults." "For housewives / househusbands" are aimed at people in a certain age group, and "For office workers" are especially "Ke" refers to people wearing business or office attire such as suits. "Adult" refers to content aimed at adults and above, and discourages advertising to minors. This relates to desirable products etc.

[0039] In addition, the "location attribute" of the characteristic information indicates the characteristics of the area targeted for advertising. In 2, there are three types of areas: "Office District," "Residential District C," and "Downtown." The "business district," "residential area," and "downtown area" are areas with office buildings, residential areas, commercial facilities, and drinking establishments, respectively. It refers to an area with many restaurants, and "Residential Area C" refers to a residential area in a specific area, as mentioned above. Shows.

[0040] In addition, the "priority" of the characteristic information is determined based on the number of ads selected for display, as described below. In Figure 2, it is set to "Low", There are three levels: "Medium" and "High." "Medium" has a higher priority than "Low." " has a higher priority than "low" and "medium".

[0041] Advertisements A1 to A3 have the following attributes: "for office workers," "location district," and priority. However, the "movement level of the ad" is different for ads A1, A2, and A3. Ad B1 is "low", "medium", and "high", and is different from each other. "Movement level" is "High", person attribute is "For office workers", location attribute is "Office district", priority Advertisements C1 and C2 have a person attribute of "housewife / househusband" and a location attribute of "residential "Residential area" and "High" priority are common. However, "Ad movement degree" is different between Ad C1 and Ad C2. C2 is "low" and "medium" respectively, which are different from each other.

[0042] The above characteristic information is generated by a device outside the display control device 20 and stored in the DB 23. Alternatively, the control unit 25 may analyze the advertisement data and store it in the DB 23 as a result of the judgment. The following describes the advertisement executed by the display control unit 256 using the example of information shown in FIG. Several examples of the selection process will be described below.

[0043] (1A) First, the display control unit 256 uses the vehicle position information and person information to display the location information stored in the DB 23. An embodiment will be described in which appropriate advertisement data is selected from the received advertisement data and displayed on the advertisement display device 12. do.

[0044] 3A and 3B are flowcharts showing an example of processing executed by the display control device 20. 3A and 3B, the processing of the display control device 20 will be described below. The receiving unit 21 receives the video data from the imaging device 11, and the driving information receiving unit 22 receives the driving information. As a part of the information, location information is acquired (step S11).

[0045] The video determination unit 254 uses the determination information to determine person information (particularly person attributes) in the video. (Step S12). The video determination unit 254 determines whether the person in the video is one person or not. If so, the person's attributes are derived as the person attributes in the video. When a plurality of people are shown in the video, the unit 254 determines whether or not there are a predetermined number of people among the people shown. If the company determines that there are more than a certain percentage of minors in the video, it will The attribute "minor" is derived as a person attribute. The threshold value for the predetermined number of people or the predetermined ratio is stored in the DB 23, and the video determination unit 2 54 executes the judgment using the threshold value. In this example, the threshold value is set to "1 person" and the video judgment unit 254, if it determines that one or more people in the picture are minors, it will " is derived as a person attribute in the video. If the attribute is not derived, the image determination unit 254 determines whether the image is derived from the most numerous person among the plurality of people. The attributes common to the objects are derived as the attributes of the people in the video. The unit 254 functions as a person attribute determination unit that determines the attributes of a person.

[0046] The position attribute determination unit 255 determines, based on the vehicle position information acquired by the traveling information acquisition unit 22, The display control unit 256 derives the location attribute of the current location of the vehicle. The position attribute determination unit 255 extracts the position attribute that matches the position attribute derived from the data and stores it as characteristic information. The information is selected as an advertisement candidate (step S13).

[0047] The display control unit 256 determines whether the video determining unit 254 has selected the advertisement candidate from among the advertisement candidates selected in step S13. The derived attributes of the person in the video correspond to the attributes of the person in the video (i.e., the attributes of the person in the advertisement candidate correspond to the attributes of the person in the video). It is determined whether there is a match between the attribute and the attribute (step S14). If there is an advertisement candidate with a person attribute that matches the person attribute of the video, the advertisement candidate is It can be said that there are areas and people that are best suited to display.

[0048] Among the selected advertisement candidates, those corresponding to the person attributes of the video derived by the video determination unit 254 If there is a candidate advertisement (Yes in step S14), the display control unit 256 displays the candidate advertisement Specifically, the display control is performed based on the priority of the display (step S15). The control unit 256 transmits the advertisement data of the advertisement candidates to the advertisement display device 12 via the advertisement transmission unit 24. The advertisement display device 12 displays the advertisement data.

[0049] If there is only one corresponding advertisement candidate, the display control unit 256 displays that one. When there are multiple corresponding advertisement candidates and the priorities of the advertisement candidates are different, the display control unit 256 The display control unit 256 displays the advertisement candidates with higher priority in priority order. As a display method, for example, any of the following methods can be used. · Display only the most highly prioritized ad candidates - High-priority ad candidates are displayed for a longer period of time than low-priority ad candidates. Display the time High-priority ad candidates are displayed more frequently within a given period than low-priority ad candidates. Show more numbers On the display unit 121 (display), advertisement candidates with high priority and advertisement candidates with low priority are displayed simultaneously. When displaying advertisement candidates with higher priority, the display area of the candidates with higher priority is larger than that of the candidates with lower priority. Listen If multiple advertisement candidates have the same priority, the display control unit 256 selects the advertisements as follows: Control the display of multiple ad candidates related to different subjects (products, services, companies, etc.) If the advertisements related to the respective targets are included, the display control unit 256 simultaneously displays the advertisement candidates related to the respective targets. For example, the display control unit 256 may display advertisement candidates for different targets within a predetermined period. In each case, they may be displayed for the same amount of time or the same number of times, or The display area may be the same.

[0050] In addition, multiple ad candidates may be ads related to the same subject, but with different "ad activity levels." If the advertisement candidates are to be displayed, the display control unit 256 may select the advertisement candidates in terms of the display frequency and the display area. Alternatively, the display control unit 256 may select the most suitable advertisement from among the advertisement candidates. Depending on the situation, one of them may be selected and displayed. This selection method will be explained later in (1B). do.

[0051] Returning to FIG. 3A, the description continues. In the determination of step S14, among the selected advertisement candidates, If there is no person attribute corresponding to the video derived by the video determination unit 254 (step S 14 No), the display control unit 256 executes the following process. Not only the selected ad candidates, but also the personal attributes of the video in the ad data stored in DB23 (i.e., whether the attributes of the person in the advertisement match those of the person in the video) In step S16, a person matching the person attributes in the video is determined (step S16). If ads with object attributes are stored in DB23, it is best to display the ad candidates. It can be said that we are in a situation where there are people like this.

[0052] Among the advertisement data stored in the DB 23, the person attributes of the video derived by the video determination unit 254 If there is a corresponding one (Yes in step S16), the display control unit 256 The advertisement data is controlled so as to be displayed based on the priority (step S17). The method of displaying based on the priority is the same as in step S15, so the explanation will be omitted. The advertisements displayed in step S17 are not as large as the advertisements displayed in step S15, but they are still useful when the vehicle is in a position. It can be said that this is an advertisement that is appropriate for the situation in which it is placed.

[0053] Among the advertisement data stored in the DB 23, the person attributes of the video derived by the video determination unit 254 If there is no corresponding advertisement (No in step S16), the display control unit 256 By not transmitting the advertisement data to the device 12, the display of the advertisement is stopped (step (Top S18).

[0054] The display control unit 256 may also determine whether the advertisements to be displayed in steps S15 and S17 are to be displayed. The information and the display time are stored as a log in the DB 23. If there is a period when ads are not displayed, the period when ads are not displayed will also be recorded as a log. Store in B23.

[0055] A specific example of the processing shown in FIGS. 3A and 3B will be further explained using the example of FIG.

[0056] As a first example, the person attribute derived in step S12 is "company employee." If the location attribute derived in S13 is "business district", the display control unit 256 performs step S 13, advertisements A1 to A3 and advertisement B1 are selected as advertisement candidates. In step S14, the personal attributes of the selected advertisement candidates, advertisements A1 to A3 and advertisement B1, are In step S15, the advertisements A1 to A3 are prioritized over the advertisement B1. Here, the display control unit 256 selects one of the advertisements A1 to A3 to display. Select one or more target advertisements, and compare the advertisements for the selected product A with advertisement B1. This allows the display to be given a higher priority.

[0057] As a second example, the person attribute derived in step S12 is "housewife / househusband" and If the location attribute derived in step S13 is "residential area C", the display control unit 256 In S13, advertisements C1 and C2 are selected as advertisement candidates. Then, the display control unit 256 proceeds to step In step S14, it is determined that the personal attributes of advertisements C1 and C2 are "housewife / househusband." In S15, at least one of the advertisements C1 and C2 is displayed.

[0058] As a third example, the person attribute derived in step S12 is "company employee" and Assume that the location attribute derived in S13 is "residential area." In this case, the display control unit 256 In step S13, advertisements C1 and C2 are selected as advertisement candidates. In step S14, the personal attribute of the selected ad candidates, Ads C1 and C2, is not "office worker." In step S16, it is determined that the person attribute is In step S16, the display control unit 256 determines whether there is any "office worker." Advertisements A1 to A3 and advertisement B1 are selected, and in step S17, advertisements A1 to A3 are compared with advertisement B1. and display it with a higher priority.

[0059] As a fourth example, the person attribute derived in step S12 is "adult" and Assume that the location attribute derived in 13 is "downtown." In this case, the display control unit 256 In step S13, the display control unit 256 selects advertisements D1 and D2 as advertisement candidates. In step S14, the personal attribute of the selected candidate advertisements D1 and D2 is "adult." In step S15, at least one of the advertisements D1 and D2 is displayed.

[0060] In this case, the image data captured by the imaging device 11 does not show any minors. While this is happening, the minor begins to appear in the video data captured by the imaging device 11. In this case, the person attribute derived in step S12 is "minor." 6 selects advertisements D1 and D2 as advertisement candidates based on the location attribute in step S13. However, in step S14, the personal attributes of the selected advertisement candidates D1 and D2 are "Unfinished". Then, in step S16, the advertisement stored in the DB 23 is It is determined whether or not the data contains a person attribute of "minor." Display control unit 256 determines in step S16 that there is no such advertisement, and in step S18 Stop the warning display.

[0061] In this way, the display control device 20 can control the content of the program when it is not meaningful to have minors as viewers. If DB23 contains advertisements that are inappropriate for minors to view, minors may You can prevent such ads from appearing wherever you are. Advertising data with the personal attribute "minor" (e.g., advertisements for educational or children's products, programs, etc.) ), or advertising data that is "general audience" (advertising aimed at everyone, including minors) In this case, in the fourth example, if the captured video data contains a minor, When the person is displayed, the display control unit 256 determines in step S16 that the person attribute is "minor" or The presence of "general" advertising data is determined, and in step S17, the advertisement is displayed. It is possible.

[0062] In this way, the display control device 20 determines whether or not the advertisement is being displayed based on the information about the person who will be viewing the advertisement and the environment in which the vehicle is located. Based on this, advertisements can be selected and displayed according to the situation. By including information such as person attributes, location attributes, and priority, the display control device 20 The system uses this information, along with person attributes and location attributes derived from video data and driving information. By comparing gender, it becomes easier to select advertisements that are more appropriate for the situation.

[0063] The above-described example can be modified as appropriate. For example, in step S12, In this case, if the video determination unit 254 determines that no person is shown in the video data, the display The control unit 256 may determine that no one is going to view the advertisement and stop displaying the advertisement. The display control device 20 executes the process from step S11 onward based on a predetermined timing. When a person appears in the video data, the advertisement selection process described above is executed. This will be done.

[0064] In step S13, the display control unit 256 selects the advertisement data stored in the DB 23. From the results, the video determining unit 254 selects, as advertisement candidates, those corresponding to the person attributes of the video derived from the video. After that, in step S14, the display control unit 256 Among the candidates, the location attribute that matches the location attribute derived by the location attribute determination unit 255 is selected as characteristic information. If there is a match, the display control unit 256 If there is no match, the ad is displayed based on the priority. The display control unit 256 displays the selected advertisement candidates based on the priority.

[0065] The display control unit 256 also controls the display of the location attribute and person attribute acquired by the processing of the control unit 25. Use only one of the information and have location attributes or person attributes that match that information. The advertisement data may be selected and the selected advertisement data may be displayed based on the priority. Furthermore, the priority of advertisements is not essential and does not have to be set.

[0066] (1B) Next, the display control unit 256 uses the vehicle speed information to display the advertisement data stored in the DB 23. An embodiment in which an appropriate one is selected from the data and displayed on the advertisement display device 12 will be described.

[0067] Figure 4 shows an example of target speeds corresponding to the degree of movement of advertisements stored in DB23. Each target speed indicates the speed at which a particular degree of movement of an advertisement is displayed. Figure 4 shows the results when the advertisement movement level is "low" and there is no target speed limit. If the movement level of the advertisement is "medium" and the target speed is "less than 7 km / h", If is "High", it indicates that the target speed is "less than 3 km / h".

[0068] The more movement an advertisement displays on a vehicle, the more appealing it is and the more attention it attracts. However, the faster the vehicle speed, the more likely it is that people will be caught in the vehicle. The time available to view ads on both platforms is becoming shorter, and people are spending more time viewing ads. The faster the vehicle is moving, the more likely people are to look at the ad. Therefore, the faster the vehicle speed, the more visible the advertisements will be. The lower the degree of movement, the higher the visibility of the advertisement. By setting a threshold for speed, we can detect advertisements with high movement when the vehicle speed is slow. The faster the vehicle speed, the lower the degree of movement of the displayable advertisement. It enhances visibility.

[0069] FIG. 5 is a flowchart showing an example of processing executed by the display control device 20. The processing of the display control device 20 will be described with reference to FIG. 5. First, the travel information acquisition unit 22 Vehicle speed information is acquired as part of the travel information (step S21).

[0070] The display control unit 256 uses the speed information acquired in step S21 and the table shown in FIG. The advertisement to be displayed on the advertisement display device 12 is selected using the above (step S22). The display control unit 256 sorts the advertisement data selected in step S22 based on the set priority. The advertisement is then displayed on the advertisement display device 12 (step S23).

[0071] As an example, let us assume that the advertisement data shown in Figure 2 is stored in DB 23. If the vehicle speed acquired in step S21 is 5 km / h, the display control unit 256 In step S22, advertisements A1, A2, C1, C2, and D1 are selected.

[0072] Here, the display control unit 256 determines whether the advertisements A1 and A2 are the same advertising target. You can also select and display either of the advertisements C1 and C2. However, in both cases, from the viewpoint of improving the appeal of the advertisement, it is necessary to make the advertisement more dynamic. It is preferable to select and display advertisements that are highly relevant. The control unit 256 selects advertisements A2 and C2.

[0073] In step S23, the display control unit 256 displays the advertisements A2, C2, and D1 in order of their respective priorities. In this case, the display control unit 256 causes the advertisement display device 12 to display the advertisement C2 The display control unit 256 displays the advertisements A2 and D1 in priority to the advertisements A2 and D1. Since the priority of 1 is the same, both are displayed equally. For the specific method, see (1 As shown in A).

[0074] In addition, when the vehicle speed increases from this display state to 10 km / h, the display control unit 256 selects advertisements A1, C1, and D1 in step S22 and then , and are displayed on the advertisement display device 12 based on their respective priorities. Advertisement C2 will replace advertisement C1, which has high visibility.

[0075] In addition, if the vehicle stops (i.e., the speed becomes 0 km / h) from this display state, the display control In step S22, the control unit 256 selects all advertisements shown in FIG. For the target advertisement, the one with the highest degree of movement is selected again. In step S23, the advertisements A3, B1, C2, and D2 with high appeal are ranked according to their priorities. The advertisement is displayed on the advertisement display device 12 based on the advertisement.

[0076] In this way, the display control device 20 controls the advertisement display device 1 based on the vehicle speed information. 2, you can change the degree of change in the image of the advertisement displayed. The device 20 can increase the visibility of the advertisement depending on the situation. When the target is changed, the displayed advertisement may be for the same target or for a different target. The advertisement may be of a different type.

[0077] The above example can be modified as needed. For example, the speed shown in FIG. The threshold value may be changed by an administrator or may be displayed on the advertisement display device 12. The amount of movement may be changed depending on the display time or number of times of advertisements with a predetermined degree of movement. The DB23 stores the display time of advertisements with a "high" degree of motion in a predetermined period. The threshold value is set to 25% or more of the period. refers to the logs stored in DB23 and determines that the degree of activity in a certain period is "high" It is determined that the advertisement was displayed for only 15% of the predetermined period. The display control unit 256 compares the threshold value of the display time with the actual display time to determine the degree of movement. It is determined that the display period of ads with a "high" score needs to be increased, and the behavior shown in Figure 4 Increase the speed threshold for "high" level. For example, set the target speed for "high" level to "5km / h." It may also be stated as "less than."

[0078] In addition, the display control unit 256 sets a speed threshold for the degree of motion "high" to achieve the above-mentioned purpose. As a result of increasing the speed threshold, if the speed threshold is the same as the speed threshold for "medium" movement, or if the difference between the two is If the speed threshold falls below a predetermined threshold, the speed threshold for the "medium" degree of movement may also be increased. In this way, the display control unit 256 adjusts the time so that advertisements with a high degree of movement are displayed for a longer period of time. Control to.

[0079] The same process can be performed for ads with a medium level of motion. This can prevent a low-quality advertisement from being displayed on advertisement display device 12 for longer than necessary.

[0080] In the above example, if the "movement level of the ad" is "low," the ad will be a single still image. If the "movement level of the advertisement" is "medium", the advertisement is composed of multiple still images. If the "Motion of the ad" is "High", the ad is composed of video. However, the definition of "advertising activity" is not limited to this.

[0081] For example, for video ads, the number of times an ad appears or a scene changes per given time A video whose number is less than a predetermined first threshold Th1 is determined to have a "low" degree of motion in the advertisement, and Videos with a second threshold value Th2 (Th2>Th1) or higher are considered to have a high degree of motion in the advertisement. However, other videos may be defined as having a "medium" degree of motion in the advertisement. Examples of videos with a "high" level of motion include advertisements for action movies and games. An example of a video with a "medium" or "low" degree of movement in an advertisement is an advertisement for a regular product or the like.

[0082] As another example, for a single still image advertisement, the number of times an advertisement or a given time period is displayed on the screen. If the number of blinks is less than a predetermined third threshold Th3, the degree of motion of the advertisement is determined to be "low"; The video whose number of times is equal to or greater than a predetermined fourth threshold Th4 (Th4>Th3) is classified as a video whose degree of movement of the advertisement is high. The degree of motion of the advertisement may be defined as "high" and other videos as "medium". The same settings can be made for multiple still image ads or videos, not just single still image ads.

[0083] In the example shown above, the "degree of motion in the advertisement" is the amount of motion in the video of a certain advertisement. However, the "movement degree of the advertisement" is defined as the degree of movement of the advertisement. It may also be defined as the frequency with which a static advertisement switches to another image.

[0084] Figure 6 shows the target values stored in DB23 corresponding to the display time per still image advertisement. This is a table showing an example of speed. Each target speed is the speed of a vehicle, and Figure 6 shows how long a still image ad is displayed. In this case, the target speed is "12km / h or more" and the display time of one still image ad is "6 seconds ", the target speed is "9km or more but less than 12km per hour", and one still image advertisement is displayed. When the time is "4 seconds", the target speed is "7km or more but less than 9km per hour". When the vehicle speed is less than 7 km / h, the degree of movement is "medium" or higher, as shown in Figure 4. Advertisements are displayed.

[0085] If the vehicle speed is 7 km / h or more, the display control unit 256 displays the advertisements stored in FIG. Select ads A1, C1, and D1 from the list and sort them based on their respective priorities. At this time, the display control unit 256 controls the display device 12 to display the vehicle's The faster the speed, the longer the display time of each still image advertisement. As mentioned above, the faster the vehicle speed, the less frequently the advertisements are switched to static advertisements. Therefore, as shown in Figure 6, we have to improve the speed and visibility of the displayed advertisements. By changing the frequency at which ads are switched depending on the situation, we can improve the visibility of ads. It is possible.

[0086] In addition, the process (1B) described above may be combined with all or any part of the process (1A). For example, in step S15 in FIG. 3A of (1A), the display control unit 2 56 selects advertisements A1 to A3 and B1 in FIG. 2, step S The processes of S21 and S22 may be executed by the display control device 20. 56 selects an appropriate advertisement from the initially selected advertisements A1 to A3 and B1 according to the vehicle speed information. In step S17, the system further identifies the advertisement that is suitable for the user and displays the identified advertisement. Even if the number of the inputs is 1 or 2, the processes of steps S21 and S22 can be executed in the same manner.

[0087] In addition, among the advertisements selected in step S15 or S17, If no advertisement corresponding to the vehicle speed information is found as a result of the process of 22, the display control unit 256 controls the display of the advertisement selected in step S15 or S17. Alternatively, control may be performed to stop the display of the advertisement.

[0088] The display control unit 256 also displays only one of the location attribute and person attribute information and the vehicle attribute information. Both speed information may be used to select the advertisements to be displayed.

[0089] In the example of FIG. 2, advertisements A1 to A3 are generated in advance by advertisement sponsors and stored in the database. However, the control unit 25 stores one or more advertisements to be advertised in the advertisement A3 of the video. extracts multiple thumbnail scenes from video ad A3, and such scenes are included in ad A1, A2 in the DB 23. This extraction process may be performed using any known technology such as machine learning. can be used.

[0090] (1C) In (1C), the display control unit 256 uses the vehicle speed information to display the advertisement display device 12. Another example of control for changing the display will be described.

[0091] FIG. 7 is a table showing an example of target speeds corresponding to the display format of advertisements stored in the DB 23. Each target speed is a vehicle speed at which the advertisement is displayed in a specific display format. Figure 7 shows whether the advertisement display format is "1" and the speed is "3km / h or more." When the display format is "4 in 1", the target speed is "less than 3 km / h". Here, the display mode "1" indicates that one advertisement is displayed on the entire screen of the display unit 121. In the display mode "4 in 1", the entire screen of the display unit 121 is divided into four, and each division Indicates that one ad will be displayed in the region.

[0092] The more ads that are displayed on a vehicle at one time, the greater the advertising effect. Therefore, since the display unit 121 is a display, the more advertisements are displayed, the more the number of advertisements per advertisement increases. As mentioned above, the faster the vehicle speed, the more area is displayed. It is desirable to improve the visibility of advertisements. Therefore, in the example shown in FIG. 7, a threshold is set for the speed. By doing so, when the car's speed is slow, the number of ads displayed at one time is increased, and The faster the speed, the fewer ads are displayed at one time, increasing visibility.

[0093] 8A and 8B show the display modes "1" and "4 in 1" of advertisements displayed on the display unit 121. 8A is a schematic diagram showing the advertisement E being displayed on the entire screen of the display unit 121. On the other hand, FIG. 8B shows that advertisements E to H are displayed on the screen of display unit 121 in a manner that divides the screen into four equal parts. This indicates that each of the images will be displayed in its respective divided area.

[0094] The advertisements E to H may be advertisements for different advertising targets, for example. The multiple advertisements may be the same advertisement or advertisements for the same advertising target. The advertisements displayed in E to H may all have the same degree of movement, or may have different degrees of movement. For example, if advertisement E is a still image advertisement for product E, For example, advertisement F may be a video advertisement for the same product E.

[0095] FIG. 9 is a flowchart showing an example of processing executed by the display control device 20. The processing of the display control device 20 will be described with reference to FIG. 9. First, the travel information acquisition unit 22 Vehicle speed information is acquired as part of the travel information (step S31).

[0096] The display control unit 256 uses the speed information acquired in step S31 and the table shown in FIG. The display format of the advertisement on the advertisement display device 12 is selected using the above (step S32). Then, the display control unit 256 displays the advertisement data in accordance with the display mode selected in step S32. Based on the set priority, the advertisement is displayed on the advertisement display device 12 (step S33).

[0097] As described above, the display control device 20 controls the advertisements to be displayed on the advertisement display device 12 in accordance with the vehicle speed information. The number and size of the advertisements to be displayed can be changed. (1B) In a different way to (1B), simplify the ads displayed when the speed is high and improve visibility. It can be done.

[0098] The display mode is not limited to two levels, but may be set to three or more levels. For example, This is a display format between the "1" and "4 in 1" display formats, where one screen is divided into two and the split area is It is also possible to set "2 in 1" where advertisements are displayed for each. In this case, Two thresholds of degree will be set.

[0099] The screen of the display unit 121 does not have to be divided evenly. For example, the display control unit 256 In the example shown in FIG. 2, when advertisements A1, C1, and D1 are displayed on the advertisement display device 12, The divided areas (display areas) may be set based on the priority of the advertisements.

[0100] 10A is a schematic diagram showing an example of setting the divided regions in the above case. 56 is based on the fact that the priority of advertisement A1 is "high" and the priority of advertisements C1 and D1 is "medium". Based on this, the display unit 121 is controlled to give priority to and display the advertisement A1 widely. In A, advertisement A1 is displayed in the left half of the screen of display unit 121, and advertisements C1 and D1 are displayed in the left half of the screen of display unit 121. Each of these is displayed in a quarter area of the screen of the display unit 121. If the speed exceeds a predetermined threshold and the advertisement display mode "1" is selected in step S32, 10B, the display control unit 256 displays the advertisement A1 with the highest priority level of “high.” In this way, the display control can be performed so that only the The control unit 256 can display multiple advertisements based on the priority of the advertisements. can.

[0101] In addition, the processing of (1C) shown above may be performed by all or any of (1A) and (1B). For example, in step S15 of (1A), the display control When the unit 256 selects the advertisements A1 to A3 and B1 in FIG. 2, the step in FIG. The processing of steps S31 and S32 may be executed by the display control device 20. When "4 in 1" is selected as the display mode, the display control unit 256 It is determined that multiple advertisements from advertisements A1 to A3 and B1 can be displayed simultaneously on one screen. For example, the display control unit 256 may select one type of advertisement from the advertisements A1 to A3 and Advertisement B1 and Advertisement B2 may be displayed on the same screen at the same time. In this case, the display area of each advertisement is equal. Alternatively, the number may be determined based on the priority of each advertisement. When "1" is selected in the display mode of 2, the display control unit 256 displays the first selected advertisement. It is determined that only one of the advertisements A1 to A3 and B1 can be displayed on one screen. In this case, the display control unit 256 selects the advertisement with the highest priority from among the advertisements and displays it as It controls the display so that it is displayed on one screen. In addition, among the initially selected ads, the one with priority " If there are two or more advertisements with a "high" rating, the display control unit 256 selects any one advertisement. and display it.

[0102] In addition, when the processes (1B) and (1C) are combined, the degree of movement of the advertisement is changed. The speed threshold (for example, the threshold shown in FIGS. 4 and 6) for displaying the image and the display mode of the display unit 121 are set. The speed thresholds for changing the speed (for example, the thresholds shown in FIG. 7) may all be different. , any of the threshold values may be a common value.

[0103] (1D) In (1D), the display control unit 256 displays the image based on the attitude of the person appearing in the captured image. Next, a control example for changing the display of the advertisement display device 12 will be described.

[0104] The image determination unit 254 uses the attitude determination information stored in the DB 23 to determine whether the person is in the image. The attitude of each person toward the advertisement is further determined and derived as personal information. is a measure of a person's feelings toward an advertisement. If the attitude is negative, indicates a person's lack of interest in advertising or negative feelings such as dislike of advertising. Conversely, if the attitude is positive, it means that the person has The person has a high interest in the advertisement or has a positive feeling toward the advertisement. The video determination unit 254 determines the facial expressions, actions, and attitudes of people in the video. For example, the video determination unit 254 may determine the facial expression of a person in the video. If the facial expression matches the predetermined first facial feature, the attitude is determined to be positive. If the facial expression matches the feature of a predetermined second facial expression, the attitude is determined to be negative. Furthermore, the video determination unit 254 compares the information on the line of sight of the person appearing in the video with the information stored in advance in the DB. The positional relationship between the display unit 121 and the imaging device 11 stored in the display unit 23 and the angle of the imaging device 11 are shown. Based on the information, it is determined whether the gaze of the person is directed to the advertisement displayed on the display unit 121. By this two-stage determination, the video determination unit 254 determines whether the advertisement of each person appearing in the video is correct. It functions as an attitude determination unit that determines the attitude toward

[0105] FIG. 11 is a flowchart showing an example of processing executed by the display control device 20. The processing of the display control device 20 will be described below with reference to FIG. 11. First, the video determination unit 254 As described above, the attitude of each person in the video data toward the advertisement is determined (step S4 1). The video determination unit 254 determines the timing and behavior of each person. Generate information.

[0106] The display control unit 256 uses the information about the attitude of each person obtained in step S41 to The display of the advertisement on the advertisement display device 12 is changed (step S42). 256 is the period during which the advertisement is displayed on the advertisement display device 12, or the period during which the advertisement is displayed on the advertisement display device 12. The control unit 12 controls the size of the area displayed on the display unit 12 to be changed. The detailed process is described below.

[0107] For example, the display control unit 256 may determine whether the number of people in the video data is equal to or greater than a predetermined threshold. Assume that a percentage of people have a negative attitude toward the advertisement. The predetermined threshold value used for this determination is stored in the DB 23. Based on the results of the judgment, 56 determines whether a person has a negative attitude toward the advertisement. The advertisement information of the advertisement displayed on the advertisement display device 12 is obtained by referring to the log of DB23. and obtain it.

[0108] The display control unit 256 displays the advertisements in which the person has a negative attitude based on the acquired advertisement information. If it is determined that an advertisement is being displayed, the display will be immediately terminated and the advertisement will be treated as an advertisement-related The elephant may display different ads, or ads in which the person has a negative attitude, and The time or number of times that the advertisement and the advertisement target are to be displayed is shorter than the originally planned time or number of times. In this way, the display control unit 256 can display the advertisement on the advertisement display device. Alternatively, the display control unit 256 may reduce the period for which the person is displayed in the negative. Even if the size of the area in which the advertisement that has taken a bad attitude is displayed on the display unit 121 is made smaller than the initial size, good.

[0109] As an opposite example, the display control unit 256 may detect a person in the video data with a pixel value equal to or greater than a predetermined threshold value. Assume that the number or percentage of people who have a positive attitude toward the advertisement The predetermined threshold value used for this determination is stored in the DB 23. Based on the result of the judgment, the department 256 determines whether the person has a positive attitude toward the advertisement. The advertisement information of the advertisement displayed on the advertisement display device 12 at the time of the advertisement is stored in the log of the DB 23. Refer to and obtain.

[0110] The display control unit 256 displays the advertisements to which the person has taken a positive attitude based on the acquired advertisement information. If an advertisement is determined to be in display, even if the advertisement time has ended, the advertisement may be displayed once or twice. The same advertisement may be displayed more than once. It is determined that a certain number or percentage of people do not have a positive attitude toward the advertisement. Alternatively, the display control unit 256 may perform the process until the person has a positive attitude. The time or number of times that the advertisement and the advertisements with the same target audience will be displayed will be shorter than originally expected. In this way, the display control unit 256 can display the advertisement for a longer period of time or a greater number of times than the previously set period. The period of time for which the advertisement is displayed on the advertisement display device 12 is increased. Alternatively, the display control unit 256 The size of the area in which the advertisements in which the user has a negative attitude are displayed on the display unit 121 is increased from the initial size. You can make it bigger.

[0111] The display control unit 256 determines whether or not a number or percentage of people equal to or greater than a predetermined threshold value are interested in the advertisement. The number or percentage of people who have a positive attitude and who are above a certain threshold are positive about the advertisement. If we determine that you have a negative attitude, we will take measures to prevent the display of advertisements from being inappropriate. Alternatively, neither of the above processes may be performed. .

[0112] As described above, the display control device 20 displays advertisements in accordance with the person's attitude toward advertisements. the period of time the advertisement is displayed on the display device 12, or the size of the area in which the advertisement is displayed on the advertisement display device 12. In this way, the display control device 20 can change at least one of the following. This makes it easier to provide ads that you feel are appropriate, thereby increasing the effectiveness of your ads.

[0113] The processing of (1D) shown above may be carried out in whole or in part by (1A), (1B), and (1C). For example, the advertisement data shown in Figure 2 is stored in DB23. If the advertisement A3 is displayed, in step S23 of (1B), the display control unit 256 , B1, C2, and D2 are displayed on the advertisement display device 12 based on their respective priorities. At this time, as a result of the processing of steps S41 and S42 in FIG. 11, the display control unit 25 6 indicates that the person has a negative attitude towards advertisement A3 and a positive attitude towards advertisement B1. In this case, the display control unit 256 Control to shorten the period during which the notice A3 is displayed, or control to make the display area smaller than the initial On the other hand, the display control unit 256 executes at least one of the following: At least one of the following: a control to lengthen the interval between the images, or a control to enlarge the display area from the initial The display control unit 256 executes this control based on the priority of the advertisement A3 stored in the DB 23. from "medium" to "low", or change the priority of advertisement B1 from "low" to "medium" or "high" This can also be done by raising the

[0114] As another example, as a result of the process (1C), the display unit 121 may display a message such as that shown in FIG. 8B. Assume that an advertisement is being displayed. Here, the processing of steps S41 and S42 in FIG. As a result, the display control unit 256 determines that the person has a positive attitude toward the advertisement E. Assume that we have determined that the person has a negative attitude toward advertisement G. The display control unit 256 controls to lengthen the period during which the advertisement E is displayed, or to extend the display area. At least one of the following two controls is performed: At least one of the following two controls is performed: For example, as shown in FIG. 8A, the display control unit 256 controls only the advertisement E. may be displayed on the display unit 121. As another example, the display control unit 256 may display the advertisement G. Advertisement E is displayed in the left half of the display unit 121 including the original display area of advertisement G. In this case, advertisements F and H will be displayed as they are.

[0115] It should be noted that the above description of the first embodiment is merely an example, and other variations are possible. For example, the types of characteristic information are not limited to those shown above. In addition, in (1B) and (1C), the number of settings for the degree of movement of the advertisement was set to 3, but the number of settings was Any other number may be used.

[0116] The video determination unit 254 uses the determination information stored in the DB 23 to determine whether or not the video is Determine whether or not the number or percentage of people who are over a certain age is greater than or equal to a certain number. It is also possible to set the number of people over a certain age in the video, or the percentage of people over a certain age. If the video determination unit 254 determines that the advertisement is to be displayed on the advertisement display device 12, the display control unit 256 This can be controlled to improve the visibility of the advertisements displayed.

[0117] For example, if the "movement level of the advertisement" is set as shown in (1B), The display control unit 256 sets the "movement degree of the advertisement" to be displayed to a predetermined degree of movement or less. For example, in the example of the advertisement shown in FIG. 2, the advertisement display device 12 displays an advertisement with a "high" degree of movement. When the notification A3 is displayed, if there are a specified number or a specified percentage of people over a specified age When the video determination unit 254 determines that the advertisement is to be displayed, the display control unit 256 The advertisement to be displayed is referred to as advertisement A1 or A2. , the advertising movement can be reduced while the advertising targeting remains the same.

[0118] In addition, when the advertisement display device is displaying advertisement B1 with a "high" degree of movement, If the display control unit 254 makes a similar determination, the display control unit 256 determines whether the degree of movement is "medium" or "low." The advertisement may be an advertisement for another advertising target, and may be displayed on the advertisement display device. As shown in (1B), the advertisements displayed on the map are based on location attributes, person attributes, and speed information. The advertisements may be selected based on the user's preference or may be selected based on the priority of the advertisements. For example, the control unit 25 selects one or more advertisements to be advertised from the advertisement B1 having a "high" degree of movement. The display control unit 256 extracts scenes with a number of thumbnails, and sorts such scenes by the degree of motion. It is also possible to display the advertisement as a "medium" or "low" advertisement. The thresholds for age, number of people or percentage of people used in the The upper limit of "no" is stored in the DB 23 and is used by the video determination unit 254 and the display control unit 256. In addition, the "movement level of the advertisement" can be calculated by comparing the degree to which a still image advertisement is displayed with the degree to which another still image advertisement is displayed. Even if the frequency of switching to the notification is applied, the display control unit 256 can perform the same control. .

[0119] As another example, as shown in (1C), an advertisement in the "4 in 1" state is displayed on the advertisement display device 1. If the number of people over a certain age is greater than or equal to a certain percentage, When the video determination unit 254 determines that the display state is "2 in 1" or However, the display control unit 256 controls the number of advertisements displayed on one screen to be "1". If the control is to reduce the number of ads and increase the display area per ad, then implement other controls. In addition, which advertisement should be left displayed on the display unit 121 can be determined by the method shown in (1C). As mentioned above, the age and number of people or percentages used for the judgment may be determined based on priority. The threshold value is stored in DB23.

[0120] As people age, they tend to have difficulty seeing fast-moving screens and small objects. The video determination unit 254 determines whether there are many people over a predetermined age by determining the video. In accordance with the result of the determination, the display control unit 256 improves the visibility of the displayed advertisement. This makes it user-friendly for people over a certain age. It is possible to display advertisements.

[0121] The display control unit 256 determines the priority of the advertisement based on the display priority of the advertisement stored in the log of the DB 23. It may also be modified based on frequency (display time or number of times). For example, the example advertisement shown in FIG. In this case, the display control unit 256 determines the display time or number of times of the advertisement B1 from the data stored in the log. It may be determined whether the number of times is equal to or greater than a predetermined threshold. In this case, the display control unit 256 changes the priority of the advertisement B1 from "low" to "medium" or "high." Next, the display control unit 256 makes a similar determination. In this case, if the display time or number of times of advertisement B1 is equal to or exceeds a predetermined threshold, the priority of advertisement B1 is You can reset the level to "low."

Each part will be explained in detail.

[0132] The person information receiving unit 41 is a hardware component that receives person information transmitted from the video assessment device 31. The personal information receiving unit 41 outputs the received personal information to the control unit 45. To exert effort.

[0133] The advertisement information receiving unit 42 receives the advertisement information transmitted from the advertisement transmitting unit 324 of the advertisement display device 32. The advertising information receiving unit 42 is a hardware interface for receiving the received advertising information. The information is output to the control unit 45.

[0134] The travel information acquisition unit 43 acquires the travel information of the vehicle in the same manner as the travel information acquisition unit 22 according to the first embodiment. The vehicle's location information and speed information are acquired as information. Detailed information about the road configuration of the side (e.g., roads around the vehicle that the vehicle can travel on, Information on areas where parking is possible) may also be included.

[0135] DB44 is a geographical information required to determine the location attributes of the vehicle's current location. The DB44 stores map information and vehicle route information. Memory, memory cards, HDD (Hard Disk Drive) and other recording media The DB 44 may also be provided outside the speed control device 40. In this case, The control device 40 is connected to the DB 44 via an information transmitting / receiving unit (not shown), and the data stored in the DB 44 is In addition, the DB 44 may also store data relating to the degree of movement or display form of the advertisement. The DB44 also stores a table showing the relationship between the speed of the object and the target. Various thresholds used in the process are stored.

[0136] The control unit 45 uses at least the advertisement information, person information, and driving information acquired by the speed control device 40. At least one of the speed and the course of the vehicle is set using either one of the above. The vehicle's engine and tire orientation are adjusted so that the vehicle travels at a set speed and on a set course. Control.

[0137] 12C is a block diagram of the control unit 45. The control unit 45 includes a memory 451, an I / O unit The memory 451 and the I / O unit 452 are the same as those in the embodiment. 1, the memory 251 and the I / O unit 252 are the same as those in the first embodiment, and therefore the description thereof will be omitted.

[0138] The information processing unit 453 may be implemented by any processor, similar to the information processing unit 253 according to the first embodiment. The information processing unit 453 receives software (computer program) from the memory 451. By reading and executing the program, the functions of the speed / route control unit 454 and the like are realized. The function of the speed / route control unit 454 will be described below.

[0139] The speed / route control unit 454 calculates the speed and route based on the travel information and the travel route of the vehicle stored in the DB 44. However, the speed and route control unit 454 determines the speed and route of the vehicle based on the The advertising information received by the advertising information receiving unit 42 is further used to determine the speed and route of the vehicle. This can be done.

[0140] For example, DB44 shows the relationship between the degree of movement of advertisements and the target speed, as shown in Figure 4. The speed / route control unit 454 may store a table. Determine whether the current ad's activity is "low," "medium," or "high" If the degree of movement of the advertisement is "low", there is no speed limit, so the speed and route control unit 4 54 determines the speed and direction of the vehicle based on the driving information and the driving route. If the degree of movement of the advertisement is "medium" or "high," as shown in Figure 4, "less than 7 km / h" In this case, the speed and route control unit 45 4 sets the speed based on the driving information and driving route to meet the conditions of this speed limit. do.

[0141] FIG. 13A is another example of a table stored in the DB 44, showing the cost per still image advertisement. The speed and route control unit 454 indicates the target speed corresponding to the display time of the advertisement information. Based on this information, the display time for each still image advertisement currently being displayed is set to "4 seconds," Determine whether the display time is "6 seconds" or "9 seconds." If the display time is "9 seconds," The route control unit 454 determines the speed and route of the vehicle based on the travel information and the travel route. However, if the display time is "4 seconds" or "6 seconds", the speed / route control unit 454 To meet the speed limit of "less than 8 km / h" or "less than 4 km / h", driving information and The speed and direction of the vehicle are determined based on the road and route.

[0142] FIG. 13B is another example of a table stored in the DB 44, which corresponds to the display format of the advertisement. The speed and route control unit 454 determines the target speed based on the advertisement information. Determine whether the display format of the displayed advertisement is "1" or "4 in 1". If the display time is "1", the speed / route control unit 454 determines the speed and route based on the travel information and the travel route. Determines the vehicle's speed and course. However, if the display time is "4 in 1", the speed The route control unit 454 controls the driving information and the speed limit of "less than 3 km per hour." The speed and direction of the vehicle are determined based on the road and route.

[0143] The speed and route control unit 454 also uses person information to determine the speed and route of the vehicle. For example, the speed and route control unit 454 may determine the speed and route based on the person information output by the video assessment device 31. Based on the information, it is determined whether there are many people at a location that is more than a predetermined distance away from the vehicle. "There are many people" may also mean, for example, that there are a predetermined number of people or more. Or, the number of people is large compared to the number of people within a certain distance from the vehicle. The above-described threshold values or rules for determination are stored in the DB 44.

[0144] In the above example, the speed / route control unit 454 adjusts the speed so as to satisfy the speed limit conditions. For example, the speed and route control unit 454 may set the route based on the information included in the travel information. Based on the information on the area where the vehicle can stop, the speed is controlled to stop the vehicle in that area. and may re-establish course.

[0145] When there are many people at a location that is more than a predetermined distance away from the vehicle, the speed / route control unit 454 Based on the information on roads that the vehicle can travel around the vehicle, which is included in the travel information, It is determined whether it is possible to approach the distant location further from the vehicle's current position. If possible, the speed and route control 454 adjusts the vehicle's speed and The speed and route control unit 454 determines the route based on information on the area where the vehicle can stop. If it is determined that an area where the vehicle can stop is located around the remote location, the vehicle will stop in that area. The speed and route control unit 454 may determine the speed and route of the vehicle so as to The vehicle is oriented so that a person in an approaching location can see the display unit 321. If close approach is not possible, the speed and course control The control unit 454 keeps the vehicle at its current location or its surroundings so as not to leave areas where there are many people. The vehicle may be controlled to stop in a certain area where it can be stopped.

[0146] As another example, the speed / route control unit 454 may adjust the speed and route of the advertisement displayed on the advertisement display device 32. The object attributes are acquired as advertising information. Then, based on the person information output by the video judgment device 31, Based on this, the area around the vehicle is divided into multiple areas, and the attributes of people present in each area are referenced. The area with the most people with personal attributes that match the personal attributes of the advertisement may be determined. The speed / path control unit 454 then determines whether the area with the most people is within a predetermined distance from the vehicle. If the vehicle is far away, the system checks whether the vehicle is approachable or not, as described above. It performs a process to determine whether the person is approaching the area with the most people, and ensures that the advertisement is displayed. Control to.

[0147] As yet another example, the speed / route control unit 454 may be configured to If the advertisement is advertisement D1 shown in FIG. 2 (i.e., an advertisement for "adults"), the video judgment device 3 Based on the person information output by 1, it may be determined whether or not there is a minor in the video. If there is even one minor in the vehicle, the speed / route control unit 454 will Alternatively, the vehicle is positioned so that the display unit 321 faces the vehicle in a blind spot from the minor. The speed and course of the vehicle can be determined.

[0148] In addition, the speed and route control unit 454 determines the speed and route of the person derived by the image assessment device 31 as person information. Based on the attitude information, the speed and course of the vehicle may be determined. The details are as shown in (1D).

[0149] For example, the speed and route control unit 454 detects an object exceeding a predetermined threshold in the video based on the person information. Whether or not the number or percentage of people have a negative attitude toward the advertisement Good. The number or percentage of people who are judged to have a negative attitude is equal to or greater than a predetermined threshold. In this case, the speed and route control unit 454 moves away from the person with a negative attitude, or The speed and direction of the vehicle are adjusted so that the display unit 321 is positioned in a blind spot for the person. You can decide your future path.

[0150] Conversely, the speed and route control unit 454 detects people in the video who are over a predetermined threshold based on the person information. It may be determined whether a number or percentage of people have a positive attitude toward the advertisement. If it is determined that the number or percentage of people who have a positive attitude is equal to or exceeds a predetermined threshold, In this case, the speed / path control unit 454 executes the process of determining whether or not the vehicle is approachable, as described above. , and controls to get as close as possible to such people and ensure that advertisements are shown. As stated above.

[0151] In addition, various variations described in the first embodiment can be applied to the second embodiment. It can be applied to the processing.

[0152] FIG. 14 is a flowchart showing an example of processing executed by the speed control device 40. The processing of the speed control device 40 will be described below with reference to FIG. 14. First, the advertisement information receiving unit 42 The advertisement information is received from the advertisement display device 32 (step S51).

[0153] Then, the speed / route control unit 454 uses the various information obtained in steps S51 and S52. The speed and course of the vehicle are controlled based on the above information (step S53). do.

[0154] As described above, the speed control device 40 controls the speed of the displayed advertisements when the degree of movement of the displayed advertisements is high or when the number of the displayed advertisements is high. When there are many advertisements and the display area per advertisement is small, the speed of the vehicle is slowed down or stopped. Therefore, it is possible to control the speed depending on the situation of the advertisement display. This will increase the visibility of the advertisement.

[0155] Furthermore, the speed control device 40 may determine whether or not the vehicle is moving based on information about people around the vehicle (for example, information about the attitude of people). In this case, vehicles will be provided to people who are interested in the advertisement or who have the personal attributes targeted by the advertisement. On the other hand, people who have a negative attitude towards advertising Keep the vehicle away from people or control the movement of the vehicle so that the advertisements are not visible to people. In this way, the speed control device 40 can make the advertisement appear more effectively. Or it can prevent the advertisement from giving a bad impression.
