Description

Video management device, video management system, method and program

[0001] The present disclosure relates to a video management device, a video management system, a video management method, and a video management program that manage captured video.

[0002] In situations where remote video surveillance is performed, personal information may appear in the collected video, so it is desirable to handle such personal information appropriately.

[0003] For example, Patent Document 1 describes smart glasses that prevent the leakage of confidential information. When capturing video data and transmitting it to a support center server, the smart glasses described in Patent Document 1 mask areas of the image frame that include confidential customer information and areas that include text information.

[0004] Japanese Patent Application Laid-Open No. 2023-141478

[0005] On the other hand, if too much emphasis is placed on the prevention of confidential information leaks, it becomes difficult to quickly obtain the necessary video when a situation arises in which the captured video itself is needed, such as in an emergency. Therefore, it is preferable to be able to quickly obtain the captured video when needed, while preventing the leakage of confidential information captured in the video.

[0006] Therefore, the present disclosure aims to provide a video management device, a video management system, a video management method, and a video management program that can obtain video captured according to the situation while preventing the leakage of information captured in the video.

[0007] The video management device according to the present disclosure is characterized by comprising an imaging unit that captures a first video, a registration unit that registers the first video in a memory unit, a video processing unit that generates a second video in which the first video has been subjected to concealment processing, a second video transmission unit that transmits the second video to another device, and a first video transmission unit that, when a predetermined situation is detected from the first video or the second video, transmits the first video including the period in which the situation was detected to the other device.

[0008] The video management system according to the present disclosure comprises a video management device that manages captured video and a server that receives video managed by the video management device, and is characterized in that the video management device comprises an imaging unit that captures a first video, a registration unit that registers the first video in a memory unit, a video processing unit that generates a second video by applying a concealment process to the first video, a second video transmission unit that transmits the second video to another device, and a first video transmission unit that, when a predetermined situation is detected from the first video or the second video, transmits a first video including the period during which the situation was detected to the server.

[0009] The video management method according to the present disclosure is characterized by capturing a first video, registering the first video in a memory unit, generating a second video by applying a concealment process to the first video, transmitting the second video to another device, and when a predetermined situation is detected from the first video or the second video, transmitting the first video including the period during which the situation was detected to the other device.

[0010] The video management program according to the present disclosure is characterized in that it causes a computer to execute a registration process for registering a captured first video in a memory unit, a video process for generating a second video in which a concealment process has been applied to the first video, a second video transmission process for transmitting the second video to another device, and a first video transmission process for transmitting the first video including the period in which a predetermined situation is detected from the first video or the second video to another device when the predetermined situation is detected from the first video or the second video.

[0011] According to the present disclosure, it is possible to obtain video captured according to the situation while preventing the leakage of information captured in the video.

[0013] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0014] 1 is a block diagram showing a configuration example of a first embodiment of a video management system according to the present disclosure. The video management system 1 of the first embodiment includes a video management device 110 and a server 210.

[0015] The video management device 110 is a device that manages captured video. The video management device 110 is realized, for example, as an edge terminal. The video management device 110 includes a storage unit 111, an imaging unit 112, a registration unit 113, a video processing unit 114, a second video transmission unit 115, a detection unit 116, an inquiry unit 117, and a first video transmission unit 118.

[0016] The storage unit 111 stores data required when the video management device 110 performs various processes. The storage unit 111 also stores video captured by the imaging unit 112, which will be described later. The storage unit 111 is realized by, for example, a magnetic disk.

[0017] The imaging unit 112 captures video of the monitoring target. Note that, to distinguish the video captured by the imaging unit 112 from video processed by the video processing unit 114 (described later), the video itself captured by the imaging unit 112 is referred to as a first video. That is, the imaging unit 112 captures the first video. The imaging unit 112 is, for example, a camera.

[0018] The imaging unit 112 may be implemented in a device different from the video management device 110 and connected to the video management device 110 via a communication line. However, if the imaging unit 112 is implemented in a device different from the video management device 110, it is preferable that the imaging unit 112 be connected to the video management device 110 directly or via a dedicated line to prevent information leakage.

[0019] The registration unit 113 manages the video to be stored in the storage unit 111. Specifically, the registration unit 113 registers the first video captured by the imaging unit 112 in the storage unit 111. The registration unit 113 also deletes the first video from the storage unit 111 after a predetermined period (hereinafter referred to as the first period) has passed since registration. The period until deletion is predetermined by the user or the like. The process of deleting data by the registration unit 113 will be described later.

[0020] The video processing unit 114 generates a video (hereinafter referred to as a second video) in which a concealment process has been applied to the first video. In the present disclosure, the video processing unit 114 generates the second video from the first video in real time. The concealment process here is, for example, a process of obscuring a video of an area in which information predetermined as information to be concealed is captured to the extent that the information cannot be visually recognized, and examples of such a process include blurring and mosaic processing. Examples of information to be concealed include information indicating personal information.

[0021] The method by which the video processing unit 114 performs the concealment process on the video is arbitrary. Note that the process of identifying an area in the video where predetermined information is captured and obscuring it is widely known, and therefore a detailed description thereof will be omitted here.

[0022] The second video transmission unit 115 transmits the video on which the concealment process has been performed (i.e., the second video) to the server 210. In this embodiment, the destination of the second video is the server, but the destination may be any destination, such as a tablet terminal or a portable terminal.

[0023] In this way, the second video transmission unit 115 transmits the second video, which has been concealed from the first video, to another device, the server 210, thereby making it possible to prevent the leakage of information reflected in the video.

[0024] On the other hand, the detection unit 116 detects a situation predetermined by an administrator or the like from the video. The video to be detected may be the first video or the second video. In this embodiment, a case where the predetermined situation is detected from the first video will be described.

[0025] Examples of situations that represent an emergency include situations that can be seen from video, such as the occurrence of a traffic accident, the occurrence of an incident, etc. The method for detecting a situation from video is also arbitrary, and the detection unit 116 may detect a situation from video using a known method.

[0026] When a predetermined situation is detected from the video, the inquiry unit 117 inquires of the destination of the video (in this embodiment, the server 210) whether or not to transmit the first video before transmitting the first video. Specifically, when a predetermined situation is detected from the video, the inquiry unit 117 sends a notification to the destination of the video inquiring whether or not to transmit the first video, and waits for a response.

[0027] If it is determined that the first video is to be transmitted unconditionally when a predetermined situation is detected from the video, the video management device 110 does not need to include the inquiry unit 117. However, since the first video is video before concealment processing is performed, it is preferable to be able to inquire in advance about whether or not to transmit the first video.

[0028] When a predetermined situation is detected from the video, first video transmission unit 118 acquires a first video including the detected period from storage unit 111 and transmits the first video to a destination of the video (server 210 in this embodiment). In this embodiment, first video transmission unit 118 transmits the first video to server 210 when detection unit 116 detects a predetermined situation from the video.

[0029] Note that first video transmission unit 118 may transmit the first video to server 210 based on a response to an inquiry by inquiry unit 117. Specifically, first video transmission unit 118 may transmit the first video to server 210 when receiving a response indicating that the first video will be transmitted as a result of the inquiry by inquiry unit 117.

[0030] In this manner, in this embodiment, the image processing unit 114 performs a concealment process on the first image, while the detection unit 116 detects a predetermined situation from the first image. Therefore, it is possible to prevent leakage of personal information and the like captured in the image, while enabling the server 210 to quickly obtain the image captured according to the situation.

[0031] In such a situation, the registration unit 113 may delete the first video transmitted to the video destination (server 210) after a period (hereinafter referred to as a second period) longer than a predetermined period (i.e., a first period) has elapsed since registration, because the first video transmitted is considered to be in greater demand for preservation than other videos.

[0032] Specifically, the registration unit 113 may set a flag for the first video for the period in which it was sent to another device, and delete the first video for the period for which the flag was set after the second period has elapsed.

[0033] The registration unit 113, the video processing unit 114, the second video transmission unit 115, the detection unit 116, the inquiry unit 117, and the first video transmission unit 118 are realized by a computer processor (e.g., a CPU (Central Processing Unit), a GPU (Graphics Processing Unit)) that operates according to a program (video management program).

[0034] For example, the program may be stored in storage unit 111 of video management device 110, and the processor may read the program and operate, in accordance with the program, as registration unit 113, video processing unit 114, second video transmission unit 115, detection unit 116, inquiry unit 117, and first video transmission unit 118. Furthermore, the functions of video management device 110 may be provided in a SaaS (Software as a Service) format.

[0035] Furthermore, the registration unit 113, the video processing unit 114, the second video transmission unit 115, the detection unit 116, the inquiry unit 117, and the first video transmission unit 118 may each be realized by dedicated hardware. Furthermore, some or all of the components of each device may be realized by a general-purpose or dedicated circuit, processor, etc., or a combination thereof. These may be configured by a single chip, or may be configured by multiple chips connected via a bus. Some or all of the components of each device may be realized by a combination of the above-mentioned circuits, etc., and a program.

[0036] Furthermore, when some or all of the components of the video management device 110 are realized by multiple information processing devices, circuits, etc., the multiple information processing devices, circuits, etc. may be centrally or decentralized. For example, the information processing devices, circuits, etc. may be realized as a client-server system, a cloud computing system, or the like, each connected via a communication network.

[0037] The server 210 includes a receiving unit 211 , a display unit 212 , and a transmitting unit 213 .

[0038] The receiving unit 211 receives the second video from the video management device 110. The receiving unit 211 also receives an inquiry from the video management device 110 as to whether or not to transmit the first video.

[0039] Display unit 212 displays the received video. Note that display unit 212 may display information other than the received video. For example, when an inquiry about whether or not to transmit the first video is received, display unit 212 may display the content of the inquiry.

[0040] When the transmitting unit 213 receives an inquiry from the video management device 110 as to whether or not to transmit the first video, it transmits a response indicating that the first video will be transmitted or not.

[0041] Next, a description will be given of the operation of the video management system 1 of this embodiment. Fig. 2 is a flowchart showing an example of the operation of the video management system 1 of this embodiment.

[0042] The imaging unit 112 captures a first video (step S11), and the registration unit 113 registers the captured first video in the storage unit 111 (step S12). The video processing unit 114 generates a second video by performing a concealment process on the first video (step S13), and the second video transmission unit 115 transmits the second video to another device (server 210) (step S14). Note that the order of the process of step S12 for registering the first video in the storage unit 111 and the processes of steps S13 to S14 for generating and transmitting the second video to another device may be reversed.

[0043] Meanwhile, the detection unit 116 detects a predetermined situation from the first video (step S15). If the predetermined situation is not detected (No in step S16), the process of step S15 for detecting the situation from the video is repeated. On the other hand, if the predetermined situation is detected (Yes in step S16), the inquiry unit 117 inquires of the other device whether or not to transmit the first video (step S17).

[0044] If a response to transmit the first video is not received (No in step S18), the processes from step S15 onward are repeated. On the other hand, if a response to transmit the first video is received (Yes in step S18), the first video transmitter 118 transmits the first video based on the response to the inquiry (step S19).

[0045] As described above, in this embodiment, the imaging unit 112 captures a first video, and the registration unit 113 registers the first video in the storage unit 111. Furthermore, the video processing unit 114 generates a second video by performing a concealment process on the first video, and the second video transmission unit 115 transmits the second video to the server 210. Meanwhile, when a predetermined situation is detected from the first video or the second video, the first video transmission unit 118 transmits to the server 210 a first video including the period during which the situation was detected. Thus, it is possible to obtain video captured according to the situation while preventing the leakage of information captured in the video.

[0046] Embodiment 2 Next, a second embodiment of the video management system of the present disclosure will be described. In the first embodiment, the video management device 110 detects a predetermined situation from the video and determines whether to transmit the first video. In this embodiment, a method for transmitting the first video when a predetermined situation is detected at the destination of the second video will be described.

[0047] 3 is a block diagram showing a configuration example of a second embodiment of a video management system according to the present disclosure. The video management system 2 of the second embodiment includes a video management device 120 and a server 220.

[0048] Similar to the video management device 110 of the first embodiment, the video management device 120 is a device that manages captured video. The video management device 120 includes a storage unit 111, an imaging unit 112, a registration unit 113, a video processing unit 114, a second video transmission unit 115, a receiving unit 127, and a first video transmission unit 118.

[0049] That is, the video management device 120 of this embodiment differs from the video management device 110 of the first embodiment in that it does not include the detection unit 116 and the query unit 117, but includes a receiving unit 127. The rest of the configuration is the same as in the first embodiment. Note that this does not deny that the video management device 120 of this embodiment may include the detection unit 116 and the query unit 117 in the video management device 110 of the first embodiment.

[0050] Receiving unit 127 receives a notification indicating that a predetermined situation has been detected from the second video from server 220. When first video sending unit 118 receives this notification from server 220, it obtains the first video from storage unit 111 and sends it to server 220.

[0051] The registration unit 113, the video processing unit 114, the second video transmission unit 115, the receiving unit 127, and the first video transmission unit 118 are realized by a computer processor that operates according to a program (video management program).

[0052] The server 220 includes a receiving unit 211 , a display unit 212 , and a transmitting unit 223 .

[0053] That is, the server 220 of this embodiment differs from the server 210 of the first embodiment in that it includes a transmission unit 223 instead of the transmission unit 213. The rest of the configuration is the same as that of the first embodiment.

[0054] The transmitting unit 223 transmits to the video management device 120 a notification indicating that a predetermined situation has been detected from the second video. Note that the method by which the transmitting unit 223 detects the predetermined situation from the second video is arbitrary. For example, the transmitting unit 223 may automatically detect the predetermined situation from the second video using a method similar to the detection method used by the detecting unit 116. Alternatively, the transmitting unit 223 may manually detect the predetermined situation from the second video in response to an operation instruction from the user after the user checks the video displayed on the display unit 212.

[0055] Next, the operation of the video management system 2 of this embodiment will be described. Fig. 4 is a flowchart showing an example of the operation of the video management system 2 of this embodiment. The process from capturing the first video to transmitting the second video that has been subjected to the concealment process is the same as the process from step S11 to step S14 in Fig. 2.

[0056] The receiving unit 127 receives a notification indicating that a predetermined situation has been detected from the second video (step S21). Upon receiving the notification, the first video sending unit 118 sends the first video to the server 220 (step S22).

[0057] As described above, in this embodiment, when the receiving unit 127 receives a notification indicating that a predetermined situation has been detected from the second video, the first video sending unit 118 sends the first video to the server 220. Therefore, in this embodiment, the same effects as in the first embodiment can be obtained.

[0058] Next, an overview of the present disclosure will be described. Fig. 5 is a block diagram showing an overview of a video management device according to the present disclosure. A video management device 80 (e.g., video management device 110, video management device 120) according to the present disclosure includes an imaging unit 81 (e.g., imaging unit 112) that captures a first video, a registration unit 82 (e.g., registration unit 113) that registers the first video in a storage unit (e.g., storage unit 111), a video processing unit 83 (e.g., video processing unit 114) that generates a second video by performing a concealment process on the first video, a second video transmission unit 84 (e.g., second video transmission unit 115) that transmits the second video to another device (e.g., server 210, server 220), and a first video transmission unit 85 (e.g., first video transmission unit 118) that, when a predetermined situation is detected from the first video or the second video, transmits the first video including a period during which the situation was detected to another device.

[0059] With such a configuration, it is possible to obtain an image that is shot according to the situation while preventing the leakage of information captured in the image.

[0060] Furthermore, the video management device 80 may include a receiving unit (e.g., receiving unit 127) that receives a notification indicating that a predetermined situation has been detected from the second video. Then, when the first video transmission unit 85 receives the notification, it may transmit the first video to another device.

[0061] Meanwhile, the video management device 80 may include a detection unit (e.g., detection unit 116) that detects a predetermined situation from the first video or the second video. Then, the first video transmission unit 85 may transmit the first video to another device when the situation is detected by the detection unit.

[0062] Furthermore, the video management device 80 may include an inquiry unit (e.g., inquiry unit 117) that, when a predetermined situation is detected, inquires of another device whether or not to transmit the first video before transmitting the first video. Then, the first video transmission unit 85 may transmit the first video based on a response to the inquiry.

[0063] Furthermore, the registration unit 82 may delete the first video after a predetermined first period has elapsed since registration.

[0064] Furthermore, the registration unit 82 may delete the first video transmitted to another device after a second period, which is longer than the first period, has elapsed.

[0065] Specifically, the registration unit 82 may set a flag for the first video for the period transmitted to another device, and delete the first video for the period for which the flag was set after the second period has elapsed.

[0066] Furthermore, the first video may include information that is predetermined as information to be concealed, and the video processing unit 83 may perform concealment processing on the video of the area in which the predetermined information is captured.

[0067] Specifically, the first video may include personal information as information to be concealed.

[0068] Furthermore, the video processing unit 83 may perform a concealment process on the video of an area in which information predetermined as information to be concealed is captured, to obscure the video to the extent that the information cannot be visually recognized.

[0069] The predetermined situation may also be a situation that is visible from the video and indicates an emergency.

[0070] The situation indicating an emergency may be a situation indicating the occurrence of a traffic accident or an incident.

[0071] Fig. 6 is a block diagram showing an overview of a video management system according to the present disclosure. A video management system 70 (video management system 1, video management system 2) according to the present disclosure includes a video management device 80 (e.g., video management device 110, video management device 120) that manages captured video, and a server 90 (e.g., server 210, server 220) that receives video managed by the video management device. Note that the video management device 80 illustrated in Fig. 6 is similar to the video management device 80 illustrated in Fig. 5.

[0072] With such a configuration, it is possible to prevent information captured in the video from being leaked, and to obtain video that is shot according to the situation.

[0073] Furthermore, server 90 may include a transmitting unit (e.g., transmitting unit 223) that transmits a notification indicating that a predetermined situation has been detected from the second video to the video management device. Furthermore, video management device 80 may include a receiving unit (e.g., receiving unit 127) that receives the notification. Then, when first video transmitting unit 85 of video management device 80 receives the notification from server 90, it may transmit the first video to the server.

[0074] Meanwhile, the video management device 80 may include a detection unit (e.g., detection unit 116) that detects a predetermined situation from the first video or the second video. Then, the first video transmission unit 85 may transmit the first video to the server when the detection unit detects the situation.

[0075] 7 is a schematic block diagram showing the configuration of a computer according to at least one embodiment. The computer 1000 includes a processor 1001, a main memory device 1002, an auxiliary memory device 1003, and an interface 1004. The computer 1000 may also be connected to a computer that executes a mathematical programming solver, an annealing machine, a simulator, or the like.

[0076] The above-described video management device 80 is implemented in a computer 1000. The operations of the above-described processing units are stored in the form of a program (video management program) in an auxiliary storage device 1003. The processor 1001 reads the program from the auxiliary storage device 1003, loads it into the main storage device 1002, and executes the above-described processing in accordance with the program.

[0077] In at least one embodiment, the auxiliary storage device 1003 is an example of a non-transitory tangible medium. Other examples of non-transitory tangible media include a magnetic disk, a magneto-optical disk, a CD-ROM (Compact Disc Read-only memory), a DVD-ROM (Read-only memory), and a semiconductor memory connected via the interface 1004. In addition, when this program is distributed to the computer 1000 via a communication line, the computer 1000 that receives the program may load the program into the main storage device 1002 and execute the above-described processing.

[0078] The program may be a program for realizing part of the above-described functions. Furthermore, the program may be a so-called differential file (differential program) that realizes the above-described functions in combination with another program already stored in the auxiliary storage device 1003.
