[0041] The display unit 45 is configured to include at least one display interface capable of displaying data. The display interface is, for example, an LCD or an organic EL display. However, the display interface is not limited to these.

[0042] (Operation flow of the video management device) Referring to Figure 3, the operation of the video management device 30 according to this embodiment will be described.

[0043] Step S101: The input unit 41 of the terminal device 40 receives a request to specify a location on the map displayed on the screen where video footage will be acquired.

[0044] The input unit 41 of the terminal device 40 receives the user's specification of a location on the map where they want to acquire video. Next, the communication unit 42 transmits the position coordinates of that location to the communication unit 31 of the video management device 30 via the network 2.

[0045] Step S102: The control unit 33 of the video management device 30, which can communicate with the terminal device 40, displays icons on the map indicating the position and orientation of each vehicle 10 at the time the video was taken, for each vehicle 10 that has stored video footage taken within a predetermined area including a point specified on the map displayed on the screen of the terminal device 40.

[0046] Information such as the position and orientation of each vehicle 10 at the time the video was captured is necessary when selecting a video or image. However, the prior art disclosed in Patent Document 1, etc., was unable to appropriately present such information to the user.

[0047] According to this disclosure, users can instantly understand the location and orientation from which the video was taken by viewing the icons displayed on the map. This makes it easy for users to select a vehicle 10 that has stored video taken at a desired location and orientation. The display screen of the icons corresponding to each vehicle is updated at predetermined time intervals (for example, every 10 seconds).

[0048] The communication unit 21 of the data center 20 receives from each vehicle 10 at predetermined time intervals (for example, every 10 seconds) the time the video was taken, the location information of the vehicle 10 at the time the video was taken, and the captured video. The control unit 23 then stores data D, which is a combination of this information, in the storage unit 22. For example, the data D for each vehicle 10 is managed by a combination of the time of shooting (year / month / day / time), the location information of the vehicle 10, and the captured video, as shown in equation (1). The time is updated in seconds, in the format x hours, y minutes, and z seconds. Based on the location information, which is data including the position and orientation of the vehicle 10, an icon indicating the position and orientation of the vehicle 10 to be displayed on the map is generated. Data D = (Time of shooting, vehicle location information, video) (1)

[0049] The control unit 33 may allow the terminal device 40 to specify the target period for video acquisition on its screen. When the target period is specified, the control unit 33 displays icons on the map for each vehicle whose video footage was recorded within the specified area during the target period. As shown in Figure 4, by specifying the "shooting time" as "13:01" and setting the target period to "~15 minutes ago", icons indicating the position and orientation of vehicles 10 located inside a predetermined concentric area A during the time period from "12:46" to "13:01" can be plotted and displayed on the map. By setting the target period, it becomes possible to display more vehicle location information during time periods when the number of vehicles for which video can be acquired is small, thereby increasing the base number of vehicles for which video can be acquired. The "shooting time" is entered manually, but the time when video was last taken at the specified location may be entered automatically.

[0050] The control unit 33 of the video management device 30 acquires data D1 from the data center 20, which is a combination of the time and location information of the video taken by each vehicle 10 from the aforementioned data D. D1 is the data shown in the following equation (2). Based on the location information, which is data including the position and orientation of the vehicle 10, the position and orientation of the vehicle 10 to be displayed on the map are acquired. Therefore, from the data D1 of the vehicle 10, an icon indicating the position and orientation of the vehicle 10 at the time the video was taken can be generated. Data D1 = (Time of shooting, vehicle location information) (2)

[0051] When a point P for acquiring video footage is specified on the map, the control unit 33 defines a predetermined area A that includes point P. The predetermined area A may be, for example, an area represented by concentric circles extending by a predetermined radius around the specified point P, as shown in Figure 4, or an area represented by a square extending around the specified point P, but is not limited to these. As shown in Figure 4, the control unit 33 plots and displays icons on the map indicating the position and orientation of the vehicle 10 located inside the predetermined concentric area A within the specified target period.

[0052] Furthermore, the control unit 33 displays information on the screen of the terminal device 40 indicating the time the video was taken for each vehicle 10 that has video footage stored within a predetermined area A. Figure 5 is a diagram showing an example of a screen displaying information indicating the time the video was taken. In the screen shown in Figure 5, the darkly colored time slots indicate the time slots in which the video footage is stored. In other words, in the example shown in Figure 5, the time slots to which the time the video was taken belong are displayed in a visually distinguishable way as information indicating the time the video was taken. From the example shown in Figure 5, it can be seen that video footage was stored within the predetermined area A during the time slots of 9:00-9:30, 10:30-11:00, 11:30-12:00, and 13:00-13:30. Therefore, if the user checks the information displayed on the screen in Figure 5 in advance and then specifies the target period on the video acquisition screen in Figure 4, the efficiency of searching for the desired video will be improved. In the example in Figure 5, the time intervals are set to 30 minutes, but you may also set the time intervals to shorter intervals such as 10 minutes or 5 minutes, or longer intervals such as 60 minutes.

[0053] The control unit 33 may display icons on the map indicating the location and orientation of one or more vehicles 10 that have captured video footage within a predetermined area A during the target period, by changing the color of the icons according to the time. By changing the color of the icons according to the time, it becomes possible to clearly understand which time period each vehicle is from. Furthermore, it becomes possible to determine whether or not there are vehicles from which video footage can be acquired within the target period, thereby improving search efficiency.

[0054] For example, the icon colors will be explained with reference to Figure 4. (i) A black icon (represented as a dark color in Figure 4) indicates the latest position of vehicle 10 (position at the time of shooting "13:01"). (ii) A white icon (represented as white in Figure 4) indicates the past position of vehicle 10 (position during the time period from "12:46" to "13:01"). Furthermore, (iii) a green icon (represented as a grid in Figure 4) indicates the position of vehicle 10 for which video has been saved in the memory unit 32, which will be described later.

[0055] Steps S103-S104: When one or more icons displayed on the map are selected, the control unit 33 acquires video footage captured by the vehicle 10 corresponding to the selected icon.

[0056] The input unit 41 of the terminal device 40 accepts the selection of an icon when the user has selected one of the icons displayed on the map and the "Acquire Video" button in the upper right of Figure 4 is clicked. The communication unit 42 transmits this acceptance information to the communication unit 31 of the video management device 30 via the network 2.

[0057] When an icon is selected, the control unit 33 of the video management device 30 retrieves video data from the data center 20, specifically from the data D of the vehicle 10 corresponding to the selected icon at the time of shooting. After retrieving the target video, the control unit 33 applies appropriate masking to the video and then makes it playable. The playable video is stored in the storage unit 32 until a playback request is made. The masking process is, for example, a process to protect personal information, such as frosted glass processing, but is not limited to this.

[0058] Step S105: The control unit 33 plays the acquired video on the screen of the terminal device 40.

[0059] When a playback request is received, the control unit 33 plays the target video on the screen of the terminal device 40. The control unit 33 may also store a predetermined number of videos that have been played in the past as history in the storage unit 32 of the video management device 30. By retaining past history, video playback becomes possible without having to retrieve the video again from the data center 20. For example, the history videos may be stored for one month and then deleted.

[0060] Step S106: If the control unit 33 acquires further video, it returns to step S103. If it does not acquire further video, it terminates the process of acquiring and playing back video.

[0061] The control unit 33 repeatedly performs the process of acquiring and playing video until it can acquire the video desired by the user.

[0062] As described above, the video management device 30 according to this embodiment displays icons on a map indicating the position and orientation of each vehicle 10 at the time the video was taken, for each vehicle 10 that stores video taken within a predetermined area including a point specified on the map displayed on the screen of a terminal device 40 that is connected to the device for communication. When a user selects one of the icons displayed on the map, the video management device 30 acquires the video taken by the vehicle corresponding to the selected icon and plays back the acquired video.

[0063] With this configuration, icons indicating the position and orientation of the vehicle at the time of shooting, which are necessary information when selecting video from vehicle 10, are displayed on the map. This improves the technology for managing video captured by vehicles by increasing the probability of acquiring the desired video.

[0064] While this disclosure has been described based on the drawings and embodiments, it should be noted that those skilled in the art may make various modifications and alterations based on this disclosure. Therefore, it should be noted that these modifications and alterations are within the scope of this disclosure. For example, the functions, etc., included in each component or step can be rearranged in a logically consistent manner, and multiple components or steps can be combined into one or divided into two.

[0065] For example, in the embodiment described above, it is also possible to distribute the configuration and operation of the video management device 30 to multiple computers that can communicate with each other. It is also possible to provide some or all of the components of the video management device 30 in the data center 20. Furthermore, the video management device 30 may communicate with the vehicle 10 via the network 2 without going through the data center 20, and acquire data D, which is a combination of the shooting time (year / month / day / time) stored in the vehicle 10, the vehicle's location information, and the video.

[0066] In the embodiment described above, the data center 20 may receive data D1 from each vehicle 10 at predetermined time intervals, which is a combination of the time the video was captured and the location information of the vehicle 10 at the time the video was captured. In this case, when the video management device 30 selects one of the icons displayed on the map, it requests the data center 20 to transmit the video captured by the vehicle 10 corresponding to the selected icon. The data center 20, upon receiving the transmission request, may acquire the requested video from the corresponding vehicle 10 each time it receives a video transmission request, and then transmit the acquired video to the video management device 30.

[0067] Furthermore, in the embodiment described above, if two or more icons are selected on the map, the control unit 33 of the video management device 30 may acquire video corresponding to two or more icons from the data center 20 and play each acquired video side by side on the screen of the terminal device 40. However, when acquiring two or more videos from one vehicle 10 simultaneously, the speed of video acquisition may be limited by the network speed of 2, which may cause inconveniences such as slower video acquisition speeds. In contrast, if two or more icons for one vehicle 10 with different shooting times are displayed on the map, it is also possible to configure the system so that when one of the two or more icons is selected, the remaining icons are grayed out and excluded from operation. Adopting such a configuration reduces the likelihood of such inconveniences occurring.

[0068] For example, as shown in Figure 6, if icons for vehicle 10A and vehicle 10B are displayed on the map at times t1, t2, and t3, when the icon for vehicle 10A at time t1 and the icon for vehicle 10B at time t2 are selected, the other icons are grayed out and excluded from the operation. This reduces the delay in line speed compared to a configuration where all icons are selected, even when it is necessary to acquire video from two or more vehicles 10 simultaneously.

[0069] Furthermore, it is also possible to implement an embodiment in which a general-purpose computer functions as the video management device 30 according to the above embodiment. Specifically, a program describing the processing content that realizes each function of the video management device 30 according to the above embodiment is stored in the memory of the general-purpose computer, and the processor reads and executes the program. Therefore, this disclosure can also be implemented as a program that can be executed by a processor, or as a non-temporary computer-readable medium that stores said program.
