Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments of a video processing apparatus, a video processing method, and a program according to the present disclosure will be described with reference to the drawings.

[0014] <First Embodiment> FIG. 1 is a diagram showing an example of a vehicle 1 to which the video processing apparatus 15 according to the first embodiment is applied. In the example shown in FIG. 1, the vehicle 1 includes a driver monitor camera 11, a user identification device 12, an HMI (Human Machine Interface) 13, a drive recorder camera 14, and a video processing apparatus 15. The driver monitor camera 11 is disposed, for example, at the upper part of the steering column of the vehicle 1, and captures the face and a part of the upper body of the driver of the vehicle 1 (the user of the drive recorder camera 14). Further, the driver monitor camera 11 transmits the captured image data to the user identification device 12. In other examples, the driver monitoring camera 11 may be disposed at a position other than the steering column, such as, for example, the center cluster, the rearview mirror, the meter panel, the meter hood, etc. of the vehicle 1.

[0015] In the example shown in FIG. 1, the user identification device 12 uses face recognition technology to identify the user (the driver of the vehicle 1) of the driving recorder camera 14 included in the image captured by the driver monitoring camera 11, and generates identification information indicating the identification result of the user of the driving recorder camera 14. That is, in the example shown in FIG. 1, the identification of the user of the driving recorder camera 14 is performed using the image captured by the driver monitoring camera 11. The user identification device 12 transmits the identification information of the user of the driving recorder camera 14 to the video processing device 15. The HMI (Human Machine Interface) 13 has a function of receiving an operation for starting the vehicle 1 by the driver (the user of the driving recorder camera 14) who has boarded the vehicle 1. That is, the HMI 13 includes an engine switch, a power switch, etc. Further, the HMI 13 has a function of receiving an operation for requesting access to the video (recording data) captured and recorded by the driving recorder camera 14 by the driver (the user of the driving recorder camera 14) of the vehicle 1. Furthermore, the HMI 13 has a function of receiving an operation for the driver of the vehicle 1 to play back the recording data. Also, the HMI 13 has a function of receiving an operation for the driver of the vehicle 1 to edit (for example, delete, etc.) the recording data. The HMI 13 transmits a signal indicating the received operation of the driver of the vehicle 1 to the video processing device 15. The driving recorder camera 14 includes, for example, a camera that captures the front outside of the vehicle 1, a camera that captures the rear outside of the vehicle 1, a camera that captures the side outside of the vehicle 1, a camera that captures the interior of the vehicle 1, etc. That is, the driving recorder camera 14 captures the front outside of the vehicle 1, the rear outside of the vehicle 1, the side outside of the vehicle 1, the interior of the vehicle 1, etc., and generates video data. Also, the driving recorder camera 14 transmits the captured video data to the video processing device 15.

[0016] The video processing device 15 executes processing, playback, recording, etc. of the video captured by the drive recorder camera 14. The video processing device 15 is constituted by a microcomputer including a communication interface (I / F) 151, a memory 152, and a processor 153. The communication interface 151 has an interface circuit for connecting the video processing device 15 to the user identification device 12, the HMI 13, the drive recorder camera 14, etc. The memory 152 stores programs and various data used in the processing executed by the processor 153. The processor 153 has functions as an acquisition unit 3A, a video recording unit 3B, an association unit 3C, a determination unit 3D, a video playback unit 3E, and a video editing unit 3F. The acquisition unit 3A acquires the identification information generated by the user identification device 12. Also, the acquisition unit 3A acquires a signal indicating an operation to start the vehicle 1 received by the HMI 13. Further, the acquisition unit 3A acquires a signal indicating an operation to request access to the recorded data received by the HMI 13. Also, the acquisition unit 3A acquires a signal indicating an operation to play back the recorded data received by the HMI 13. Further, the acquisition unit 3A acquires a signal indicating an operation to edit (for example, delete, etc.) the recorded data received by the HMI 13. Also, the acquisition unit 3A acquires the video data captured by the drive recorder camera 14. The video recording unit 3B records (records) the video captured by the drive recorder camera 14 in, for example, the memory 152 or the like.

[0017] The association unit 3C generates association information that associates the identification information acquired by the acquisition unit 3A with the video recorded by the video recording unit 3B, and stores it in, for example, the memory 152. When the HMI 13 receives an operation to request access to the recorded data (the video captured by the drive recorder camera 14 and recorded by the video recording unit 3B), the determination unit 3D executes a determination as to whether to permit access to the recorded data. Specifically, since the recorded data constitutes part of the association information stored by the association unit 3C, when there is an access request to the recorded data, the determination unit 3D determines whether the access requester to the recorded data (the video shot by the drive recorder camera 14 and recorded by the video recording unit 3B) is the same as the user of the drive recorder camera 14 when the video was shot, based on the identification information that constitutes the other part of the association information. That is, when there is an access request to the recorded data, the determination unit 3D determines whether to permit access to the recorded data based on the identification information generated by the user identification device 12 based on the image shot by the driver monitor camera 11 and the association information stored by the association unit 3C. When the access requester to the recorded data (the video shot by the drive recorder camera 14 and recorded by the video recording unit 3B) is the same as the user of the drive recorder camera 14 when the video was shot, the determination unit 3D permits the access requester to access the recorded data. On the other hand, when the access requester to the recorded data (the video shot by the drive recorder camera 14 and recorded by the video recording unit 3B) is not the same as the user of the drive recorder camera 14 when the video was shot, the determination unit 3D restricts (i.e., does not permit) the access requester to access the recorded data.

[0018] When the determination unit 3D permits access to the recorded data, the video playback unit 3E executes the playback of the recorded data based on the operation of the HMI 13 to play back the recorded data received (i.e., displays the video recorded by the video recording unit 3B on the HMI 13). When the determination unit 3D permits access to the recording data, the video editing unit 3F executes the editing of the recording data based on the operation of editing the recording data received by the HMI 13 (that is, executes editing such as deletion of the video recorded by the video recording unit 3B).

[0019] FIG. 2 is a flowchart for explaining an example of the processing executed by the processor 153 of the video processing apparatus 15 according to the first embodiment when shooting is performed by the drive recorder camera 14. In the example shown in FIG. 2, in step S10, for example, the determination unit 3D determines whether the HMI 13 has received an operation to start the vehicle 1. If YES (that is, when the user of the drive recorder camera 14 (the driver of the vehicle 1) gets into the vehicle 1 and performs an operation to start the vehicle 1), the process proceeds to step S11. If NO, the process shown in FIG. 2 ends. In step S11, the acquisition unit 3A acquires the identification information of the user of the drive recorder camera 14 generated by the user identification device 12 using the image of the user of the drive recorder camera 14 captured by the driver monitor camera 11. In step S12, the video recording unit 3B records (records) the video captured by the drive recorder camera 14. In step S13, the association unit 3C generates and stores association information in which the identification information of the user of the drive recorder camera 14 acquired in step S11 is associated with the video recorded in step S12.

[0020] FIG. 3 is a flowchart for explaining an example of the processing executed by the processor 153 of the video processing apparatus 15 according to the first embodiment when the user of the drive recorder camera 14 requests access to the recording data (the video captured by the drive recorder camera 14 and recorded by the video recording unit 3B), etc. In the example shown in FIG. 3, in step S20, for example, the determination unit 3D determines whether the HMI 13 has received an operation to start the vehicle 1. If YES (that is, when the user of the drive recorder camera 14 (the driver of the vehicle 1) gets into the vehicle 1 and performs an operation to start the vehicle 1), the process proceeds to step S21. If NO, the process shown in FIG. 3 ends. In step S21, the acquisition unit 3A acquires the identification information of the user of the drive recorder camera 14 generated by the user identification device 12 using the image of the user of the drive recorder camera 14 captured by the driver monitor camera 11. In step S22, for example, the determination unit 3D determines whether the HMI 13 has received an operation to request access to the recorded data (the video captured by the drive recorder camera 14 and recorded (recorded) in step S12). If YES, the process proceeds to step S23. If NO, the process shown in FIG. 3 ends.

[0021] In step S23, based on the identification information that constitutes a part of the association information stored in step S13, the determination unit 3D determines whether the access requester to the recorded data (the video captured by the drive recorder camera 14 and recorded (recorded) in step S12) is the same as the user of the drive recorder camera 14 when the video was captured by the drive recorder camera 14. If YES, the process proceeds to step S24. If NO, the process proceeds to step S29. In step S24, the determination unit 3D permits the access requester to the recorded data to access the recorded data. In step S25, for example, the determination unit 3D determines whether the HMI 13 has received an operation to play back the recorded data. If YES, the process proceeds to step S26. If NO, the process proceeds to step S27. In step S26, the video playback unit 3E executes the playback of the recorded data based on the operation to play back the recorded data received by the HMI 13. In step S27, for example, the determination unit 3D determines whether the HMI 13 has received an operation to edit (e.g., delete, etc.) the recorded data. If YES, the process proceeds to step S28, and if NO, the process shown in FIG. 3 ends. In step S28, the video editing unit 3F executes the editing of the recorded data based on the operation to edit the recorded data received by the HMI 13. In step S29, the determination unit 3D does not permit access to the recorded data for the requester of access to the recorded data (i.e., restricts access).

[0022] As described above, in the vehicle 1 to which the video processing apparatus 15 of the first embodiment is applied, when the requester of access to the recorded data (the video recorded by the drive recorder camera 14 and recorded by the video recording unit 3B) is the same as the user of the drive recorder camera 14 at the time when the video was taken by the drive recorder camera 14, access to the recorded data is permitted for the requester of access to the recorded data, and when the requester of access to the recorded data is not the same as the user of the drive recorder camera 14 at the time when the video was taken by the drive recorder camera 14, access to the recorded data is restricted for the requester of access to the recorded data. Therefore, even when the drive recorder camera 14 mounted on the vehicle 1 is shared by a plurality of users, the risk that the video taken when one user is using the drive recorder camera 14 leaks to other users of the drive recorder camera 14 can be suppressed.

[0023] As described above, in the vehicle 1 to which the video processing apparatus 15 of the first embodiment is applied, without the user of the drive recorder camera 14 having to perform a special operation such as a login operation, by using the image of the user of the drive recorder camera 14 captured by the driver monitor camera 11, the identification information of the user of the drive recorder camera 14 is generated. Based on the identification information, it is determined whether the requester of access to the recorded data (the video captured by the drive recorder camera 14 and recorded by the video recording unit 3B) is the same as the user of the drive recorder camera 14 when the video was captured by the drive recorder camera 14, and permission or restriction of access to the recorded data is performed. Therefore, the convenience of the user of the drive recorder camera 14 can be improved as compared with the case where the user of the drive recorder camera 14 is required to perform a special operation such as a login operation.

[0024] <Second Embodiment> The vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied is configured in the same manner as the vehicle 1 to which the video processing apparatus 15 of the first embodiment described above is applied, except for the points described later.

[0025] FIG. 4 is a diagram showing an example of the vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied. As described above, in the example shown in FIG. 1, the vehicle 1 includes the driver monitor camera 11. On the other hand, in the example shown in FIG. 4, the vehicle 1 includes the information collection device 16 used for identifying the user of the drive recorder camera 14.

[0026] In the first example of the vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied, the information collection device 16 is constituted by a smartphone having a function as a key for receiving operations of opening and closing the door of the vehicle 1 and starting the vehicle 1. The information collection device 16 has a function of receiving authentication information such as fingerprint and password used for identifying the operator of the vehicle 1. The information collection device 16 transmits the received authentication information to the user identification device 12. The user identification device 12 identifies the user of the drive recorder camera 14 (the driver of the vehicle 1) by using the authentication information (such as fingerprint, password, etc.) received by the information collection device 16, and generates identification information indicating the identification result of the user of the drive recorder camera 14. That is, in the first example of the vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied, the identification of the user of the drive recorder camera 14 is performed by using the authentication information (such as fingerprint, password, etc.) received by a smartphone that functions as a key when starting the vehicle 1 equipped with the drive recorder camera 14.

[0027] In the second example of the vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied, the information collection device 16 is constituted by a finger vein sensor (scanner) that detects the finger vein of the driver of the vehicle 1 provided integrally with the steering device of the vehicle 1. That is, the information collection device 16 has a function of receiving biometric authentication information of the driver of the vehicle 1 (the user of the drive recorder camera 14). The information collection device 16 transmits the received biometric authentication information to the user identification device 12. The user identification device 12 identifies the user of the drive recorder camera 14 by using the biometric authentication information received by the information collection device 16, and generates identification information indicating the identification result of the user of the drive recorder camera 14. That is, in the second example of the vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied, the identification of the user of the drive recorder camera 14 is performed by using the biometric authentication information detected by a finger vein sensor integrated with the steering device of the vehicle 1.

[0028] In the third example of the vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied, the information collection apparatus 16 is constituted by a finger vein sensor (scanner) that detects the finger vein of the driver of the vehicle 1 provided near the door handle of the vehicle 1. That is, the information collection apparatus 16 has a function of receiving biometric authentication information of the driver of the vehicle 1 (user of the drive recorder camera 14). The information collection apparatus 16 transmits the received biometric authentication information to the user identification apparatus 12. The user identification apparatus 12 uses the biometric authentication information received by the information collection apparatus 16 to identify the user of the drive recorder camera 14 and generates identification information indicating the identification result of the user of the drive recorder camera 14. That is, in the third example of the vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied, the identification of the user of the drive recorder camera 14 is performed using the biometric authentication information detected by the finger vein sensor provided near the door handle of the vehicle 1.

[0029] In the fourth example of the vehicle 1 to which the video processing apparatus 15 of the second embodiment is applied, the information collection apparatus 16 is constituted by a parking monitoring camera of the vehicle 1. That is, the information collection apparatus 16 captures an image of the face of the driver of the vehicle 1 (user of the drive recorder camera 14) and transmits the captured image data to the user identification apparatus 12. The user identification apparatus 12 uses face recognition technology to identify the user of the drive recorder camera 14 (driver of the vehicle 1) included in the image captured by the information collection apparatus 16 and generates identification information indicating the identification result of the user of the drive recorder camera 14.
