Summary of the Invention

Problems to be Solved by the Invention

[0004] In the technology described in Patent Document 1, since the on / off of video recording is switched by manually operating a button, the video may be recorded unintentionally due to an operation error or the like. In particular, when the passengers of a vehicle are guests other than the owner of the vehicle, such as in a share car, the video recorded by the video recording apparatus being placed in a state where it can be accessed by others may lead to a risk of invasion of the privacy of the passengers (guests).

[0005] The present disclosure has been made in consideration of the above facts, and an object thereof is to obtain a video recording apparatus and a video recording program that can protect the privacy of a passenger when the passenger of a vehicle is not a pre-registered person.

Means for Solving the Problems

[0006] The video recording device according to the first aspect includes a determination unit that determines whether a passenger in the vehicle is a person registered in advance when the vehicle power is turned on, a recording control unit that causes the first recording unit to record the video captured by the imaging unit as a first video at least while the vehicle power is on, and a deletion unit that deletes the first video recorded in the first recording unit from when the vehicle power is turned on until the vehicle power is turned on next time when it is determined by the determination unit that the passenger in the vehicle is not a person registered in advance.

[0007] In the first aspect, when it is determined that the passenger in the vehicle is not a person registered in advance, the first video recorded in the first recording unit from when the vehicle power is turned on until the vehicle power is turned on next time is deleted after the vehicle power is turned on next time. Thereby, it is possible to prevent the first video captured by the imaging unit and recorded in the first recording unit from being placed in a state accessible by others other than the passenger during the period when the passenger in the vehicle is not a person registered in advance. Therefore, according to the first aspect, it is possible to protect the privacy of the passenger when the passenger in the vehicle is not a person registered in advance.

[0008] In the second aspect, in the first aspect, when the occurrence of an event is detected by the detection unit, the recording control unit causes the first recording unit to record the video captured by the imaging unit as a second video, and the deletion unit excludes the second video from the deletion target regardless of the determination result of the determination unit.

[0009] In the second aspect, since the second video captured and recorded in the first recording unit when the occurrence of an event is detected is saved without being deleted, the saved second video can be used as evidence video when an event such as an accident occurs.

[0010] In the third aspect, in the second aspect, the recording control unit causes the first recording unit to record the first video as an overwritable video and the second video as a non-overwritable video.

[0011] In the third aspect, by recording the second video as a non-overwriteable video, the second video captured when an event occurs can be reliably saved.

[0012] In a fourth aspect, in any one of the first to third aspects, when reproduction or output of the first video recorded in the first recording unit is instructed while the power of the vehicle is on, the first video is further reproduced and displayed on a display unit, or a video output unit that outputs the first video to a second recording unit is further included.

[0013] According to the fourth aspect, a passenger determined not to be a pre-registered person can reproduce and display the first video on the display unit or output it to the second recording unit.

[0014] A video recording program according to a fifth aspect causes a computer to determine whether a passenger of a vehicle is a pre-registered person when the power of the vehicle is turned on, record, as a first video, the video captured by a photographing unit in a first recording unit at least while the power of the vehicle is on, and when it is determined that the passenger of the vehicle is not a pre-registered person, delete the first video recorded in the first recording unit from when the power of the vehicle is turned on until the power of the vehicle is turned on next time after the power of the vehicle is turned on next time.

[0015] According to the fifth aspect, similar to the first aspect, when a passenger of a vehicle is not a pre-registered person, the privacy of the passenger can be protected.

Advantages of the Invention

[0016] The present disclosure has an effect of being able to protect the privacy of a passenger when the passenger of the vehicle is not a pre-registered person.

Mode for Carrying Out the Invention

[0018] Hereinafter, an example of an embodiment of the present disclosure will be described in detail with reference to the drawings. FIG. 1 shows an in-vehicle system 10 according to this embodiment. The in-vehicle system 10 includes a video recording device 30, and a camera 12, an event detection sensor 14, and a driver identification sensor 16 are connected to the video recording device 30, respectively.

[0019] The camera 12 is provided on the vehicle (hereinafter referred to as the host vehicle) on which the in-vehicle system 10 is mounted so that it can capture the periphery of the vehicle (for example, a first predetermined range including the front of the host vehicle and a second predetermined range including the rear of the host vehicle) as a video. The camera 12 captures the periphery of the host vehicle as a video in response to an instruction from the video recording device 30, and transmits the captured video to the video recording device 30. Note that the camera 12 is an example of the imaging unit in the present disclosure.

[0020] The event detection sensor 14 is a sensor that monitors the occurrence of events such as an accident in which the host vehicle collides with an object or a hit-and-run while the host vehicle is parked, and notifies the video recording device 30 when an event is detected. As the event detection sensor 14, for example, an acceleration sensor that detects the acceleration applied to the host vehicle, or a motion sensor that detects the motion state of an object existing around the host vehicle from the video of the periphery of the host vehicle captured by the camera 12 or the like can be applied. Note that the event detection sensor 14 is an example of the detection unit in the present disclosure.

[0021] The driver identification sensor 16 is a sensor that acquires information capable of determining whether the driver of the host vehicle is a pre-registered person (the owner of the host vehicle) or a guest (a person subject to privacy protection). As the driver identification sensor 16, for example, a biometric sensor that acquires biometric information of the driver such as the driver's fingerprint, or a camera (driver monitor) that captures the driver can be applied.

[0022] Further, the video recording device 30 is connected to a system bus 28 compliant with a standard such as CAN (Controller Area Network), and a car navigation device 18 is communicably connected to the system bus 28.

[0023] The car navigation device 18 includes a display unit 20 capable of displaying images such as maps, an input unit 22 capable of inputting information, and a USB slot 24 into which a USB memory 26 or the like can be inserted. The display unit 20 and the input unit 22 of the car navigation device 18 are used as devices that realize the UI (User Interface) of the video recording device 30, for example, when the first video recorded in the video recording area 50 (described later) of the video recording device 30 is reproduced and displayed on the display unit 20, or when the first video is recorded in the USB memory 26 inserted into the USB slot 24. Note that the USB memory 26 is an example of a second recording unit.

[0024] The video recording device (drive recorder) 30 includes a CPU (Central Processing Unit) 32 and a memory 34 such as a ROM (Read Only Memory) and a RAM (Random Access Memory). Further, the video recording device 30 includes a non-volatile storage unit 36 such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and a communication unit 38 that controls communication with the car navigation device 18 of the in-vehicle system 10 and the like. Furthermore, the video recording device 30 includes a card slot 40 into which a micro SD card 42, which is an example of a first recording unit, can be inserted.

[0025] The CPU 32, the memory 34, the storage unit 36, the communication unit 38, and the card slot 40 are communicably connected to each other via an internal bus 44. Note that the micro SD card 42 inserted into the card slot 40 is provided with a video recording area 50 for recording the video captured by the camera 12. The micro SD card 42 is an example of a first recording unit. Note that the video recording area 50 may be provided in the storage unit 36 instead of the micro SD card 42.

[0026] The video recording device 30 receives an IG signal whose signal level switches according to the on / off state of an ignition (IG) switch, and an ACC signal whose signal level switches according to the on / off state of an accessory (ACC) switch. Also, the power supply terminal of the video recording device 30 is connected to the positive terminal (+B) of the battery, and power is supplied from the battery regardless of the on / off states of the IG switch and the ACC switch. Thereby, the video recording device 30 operates regardless of the on / off states of the IG switch and the ACC switch.

[0027] The storage unit 36 stores a video recording program 46 in advance. The video recording device 30 functions as a determination unit 54, a recording control unit 56, a deletion unit 58, and a video output unit 60 shown in FIG. 2 when the video recording program 46 is read out from the storage unit 36 and expanded in the memory 34, and the video recording program 46 expanded in the memory 34 is executed by the CPU 32, and performs processing when the privacy protection function is on, which will be described later.

[0028] The determination unit 54 determines whether the driver of the host vehicle is a person who has been registered in advance when the power of the host vehicle is turned on. The recording control unit 56 causes the video captured by the camera 12 to be recorded as a first video in the video recording area 50 of the micro SD card 42 at least while the power of the host vehicle is on.

[0029] When the determination unit 54 determines that the driver of the host vehicle is not a pre-registered person, the deletion unit 58 deletes the first video recorded in the video recording area 50 of the micro SD card 42 from when the power of the host vehicle is turned on until the power of the host vehicle is turned on next time, after the power of the host vehicle is turned on next time. When the video output unit 60 is instructed to reproduce and display or output the first video recorded in the video recording area 50 of the micro SD card 42 while the power of the host vehicle is turned on, the video output unit 60 causes the display unit 20 to reproduce and display the first video or outputs the first video to the USB memory 26.

[0030] In addition, the storage unit 36 has pre-registered owner information 48 for identifying the owner of the host vehicle. The content of the owner information 48 differs according to the configuration of the driver identification sensor 16. For example, when the driver identification sensor 16 is a biometric sensor that acquires the driver's fingerprint, information representing the fingerprint of the owner of the host vehicle is pre-registered as the owner information 48. Also, for example, when the driver identification sensor 16 is a camera (driver monitor) that photographs the driver, information representing the facial feature amount of the owner of the host vehicle is pre-registered as the owner information 48.

[0031] Next, the operation of this embodiment will be described. The video recording device 30 according to this embodiment is provided with a privacy protection function. This privacy protection function is a function that protects the privacy of a guest by deleting unnecessary first videos photographed and recorded during the period when the driver of the host vehicle is a guest. In this embodiment, the video recording device 30 can turn on and off the above privacy protection function via the display unit 20 and the input unit 22 of the car navigation device 18. Then, while the privacy protection function is turned on, the video recording device 30 performs the processing when the privacy protection function is on shown in FIG. 3.

[0032] In step 100 of the processing when the privacy protection function is on, the recording control unit 56 determines whether the vehicle power is turned on based on the signal level of the IG signal or the ACC signal input to the video recording device 30. If the determination in step 100 is negative, step 100 is repeated until the determination is positive. When the vehicle power is turned on, the determination in step 100 is positive and the process proceeds to step 102.

[0033] In step 102, the determination unit 54 acquires information of the occupant sitting in the driver's seat of the host vehicle, that is, the driver, from the driver identification sensor 16. Also, in step 104, the determination unit 54 compares the driver information acquired in step 102 with the owner information 48 pre-registered in the storage unit 36 to determine whether the driver of the host vehicle is a pre-registered person (the owner of the host vehicle). Then, the determination unit 54 stores the determination result in the storage unit 36 or the like.

[0034] In step 106, the recording control unit 56 causes the camera 12 to capture the surroundings of the host vehicle and starts continuous recording in which the video received from the camera 12 is recorded as the first overwriteable video in the video recording area 50.

[0035] In step 108, the recording control unit 56 determines whether the vehicle power of the host vehicle is turned off based on the signal level of the IG signal or the ACC signal. If the determination in step 108 is negative, the process proceeds to step 110. In step 110, the recording control unit 56 determines whether an event such as an accident has been detected by the event detection sensor 14.

[0036] If the determination in step 110 is negative, the process proceeds to step 112. In step 112, the video output unit 60 determines whether the reproduction display or output of the first video recorded in the video recording area 50 of the micro SD card 42 has been instructed by the occupant via the display unit 20 and the input unit 22. If the determination in step 112 is also negative, the process returns to step 108, and steps 108 to 112 are repeated in parallel with the continuous recording started in step 106 until any determination is affirmed.

[0037] When an event is detected by the event detection sensor 14 while the power of the host vehicle is on, the determination in step 110 is affirmed and the process proceeds to step 114. In step 114, the recording control unit 56 protects the video for a predetermined time before and after the event occurrence timing detected by the event detection sensor 14 from overwriting in the continuous recording, and records it in the video recording area 50 of the micro SD card 42 as the second video that cannot be overwritten. After performing the process of step 114, the process returns to step 108.

[0038] In this way, while the power of the host vehicle is on, each time an event is detected by the event detection sensor 14, the video captured by the camera 12 is recorded and saved in the video recording area 50 of the micro SD card 42 as the second video that cannot be overwritten. This second video can be used as evidence video when an event such as an accident occurs.

[0039] Also, when the reproduction display or output of the first video is instructed while the power of the host vehicle is on, the determination in step 112 is affirmed and the process proceeds to step 116. In step 116, the video output unit 60 reproduces and displays the first video on the display unit 20 or outputs the first video to the USB memory 26 (extraction of the first video) in response to the instruction from the occupant. After performing the process of step 116, the process returns to step 108.

[0040] When the power supply of the host vehicle is turned off, the determination in step 108 is affirmed and the process proceeds to step 118. In step 118, the recording control unit 56 determines whether the power supply of the host vehicle has been turned on based on the signal level of the IG signal or the ACC signal. If the determination in step 118 is negated, the process proceeds to step 120.

[0041] In step 120, the recording control unit 56 determines whether an event during parking such as a collision against the host vehicle has been detected by the event detection sensor 14. If the determination in step 120 is also negated, the process returns to step 118, and steps 118 and 120 are repeated until any determination is affirmed.

[0042] When an event is detected by the event detection sensor 14 while the power supply of the host vehicle is off (when a parking event occurs), the determination in step 120 is affirmed and the process proceeds to step 122. In step 122, the recording control unit 56 turns on the power supply of the camera 12 and activates the camera 12 by supplying the power supplied from the positive terminal +B of the battery to the camera 12.

[0043] Also, in the next step 124, the recording control unit 56 protects the video captured by the camera 12 during a predetermined time from the occurrence of the parking event from overwriting in the continuous recording, and records it as a second non-overwritable video in the video recording area 50 of the micro SD card 42. When the process of step 124 is performed, the power supply of the camera 12 is turned off and the process returns to step 118.

[0044] In this way, while the power supply of the host vehicle is off, each time a parking event is detected by the event detection sensor 14, the camera 12 is activated, and the video captured by the camera 12 is recorded and saved as a second non-overwritable video in the video recording area 50 of the micro SD card 42. This second video can be used as evidence video when a parking event such as a collision during parking occurs.

[0045] When the power supply of the host vehicle is turned on, the determination in step 118 is affirmed and the process proceeds to step 126. In step 126, the deletion unit 58 determines whether or not the driver of the host vehicle was determined to be a person pre-registered by the driver of the host vehicle in step 104 executed when the host vehicle was last powered on.

[0046] If the determination in step 126 is affirmed, since the driver at the time of the last power-on of the host vehicle is a pre-registered person (the owner of the host vehicle), there is no concern of privacy infringement regarding the first video recorded in the video recording area 50. Therefore, when the determination in step 126 is affirmed, the process returns to step 102 and the processes after step 102 are performed.

[0047] On the other hand, if the determination in step 126 is negated, since the driver at the time of the last power-on of the host vehicle is a guest, leaving the first video recorded in the video recording area 50 in a state accessible to others may lead to privacy infringement of the guest. Therefore, when the determination in step 126 is negated, the process proceeds to step 128. Then, in step 128, the deletion unit 58 deletes the always-recorded video (the first video) recorded in the video recording area 50 from the time of the last power-on of the host vehicle to the time of the current power-on of the host vehicle from the video recording area 50. After performing the process of step 128, the process returns to step 102 and the processes after step 102 are performed.

[0048] As described above, in the present embodiment, the determination unit 54 determines whether the occupant of the host vehicle is a person registered in advance when the power of the host vehicle is turned on. The recording control unit 56 causes the video recorded by the camera 12 to be recorded as the first video in the video recording area 50 at least while the power of the host vehicle is on. And when it is determined by the determination unit 54 that the occupant of the host vehicle is not a person registered in advance, the deletion unit 58 deletes the first video recorded in the video recording area 50 from when the power of the host vehicle is turned on until the power of the host vehicle is turned on next time after the power of the host vehicle is turned on next time. Thereby, when the occupant of the host vehicle is not a person registered in advance, the privacy of the occupant can be protected.

[0049] Also, in the present embodiment, when the recording control unit 56 detects the occurrence of an event by the event detection sensor 14, the recording control unit 56 causes the video recorded by the camera 12 to be recorded as the second video in the video recording area 50 of the micro SD card 42, and the deletion unit 58 excludes the second video from the deletion target regardless of the determination result of the determination unit 54. Thereby, the second video that is saved without being deleted can be used as evidence video at the time of the occurrence of an event such as an accident.

[0050] Also, in the present embodiment, the recording control unit 56 records the first video as an overwritable video in the video recording area 50, and records the second video as a non-overwritable video in the video recording area 50 of the micro SD card 42. Thereby, the second video captured when the occurrence of an event is detected can be surely saved.

[0051] Also, in the present embodiment, when the video output unit 60 is instructed to play or output the first video recorded in the video recording area 50 of the micro SD card 42 while the power of the host vehicle is on, the video output unit 60 causes the first video to be played and displayed on the display unit 20, or outputs the first video to the USB memory 26. Thereby, an occupant determined not to be a person registered in advance can play and display the first video on the display unit 20 or output it to the USB memory 26.

[0052] In the above-described embodiment, the mode in which the camera 12, which is an example of the photographing unit, photographs the front and rear of the host vehicle has been described. However, the present disclosure is not limited to this. For example, the camera 12 may include a camera that photographs the interior of the host vehicle (e.g., a driver monitor, etc.).

[0053] Also, in the above-described embodiment, the mode in which the driver identification sensor 16 is configured to acquire information capable of determining whether the driver of the host vehicle is the owner or a guest of the host vehicle whose driver has been registered in advance has been described. However, the present disclosure is not limited to this. For example, the driver identification sensor 16 may be equipped with a function of determining whether the driver of the host vehicle is the owner or a guest of the host vehicle whose driver has been registered in advance (a function of performing the process of step 106 in FIG. 3), and the video recording device 30 may be configured to acquire the result of the above-described determination from the driver identification sensor 16.

[0054] Also, in the above-described embodiment, the mode in which it is determined whether the driver of the host vehicle, which is an example of an occupant of the vehicle in the present disclosure, is a pre-registered person has been described. However, the present disclosure is not limited to this. For example, the occupant of the vehicle to be determined as to whether or not they are a pre-registered person may be an occupant other than the driver.

[0055] Also, in the above-described embodiment, the mode in which the recording control unit 56 causes the video recorded by the camera 12 to be recorded in the video recording area 50 as the first video while the power of the host vehicle is on has been described. However, the present disclosure is not limited to this. For example, in addition to when the power of the host vehicle is on, the video recorded by the camera 12 may also be recorded in the video recording area 50 as the first video while the power of the host vehicle is on.

[0056] Also, in the above, the mode in which the video recording program 46, which is an example of the video recording program according to the present disclosure, is pre-stored (installed) in the storage unit 36 has been described. However, the video recording program according to the present disclosure can also be provided in a form recorded on a non-temporary recording medium such as an HDD, an SSD, or a DVD.
