For example, if the driver identification sensor 16 is a biosensor that acquires the driver's fingerprint, information representing the fingerprint of the owner of the vehicle is registered in advance as the owner information 48 . Further, for example, when the driver identification sensor 16 is a camera (driver monitor) that captures the image of the driver, the owner information 48 is registered in advance with information representing facial features of the owner of the vehicle. be.

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 to protect the guest's privacy by deleting the unnecessary first video that was taken and recorded while the driver of the own vehicle was the guest. In this embodiment, the video recording device 30 can turn on/off the privacy protection function via the display unit 20 and the input unit 22 of the car navigation device 18 . While the privacy protection function is on, the video recording device 30 performs the privacy protection function-on process shown in FIG.

At step 100 of the privacy protection function ON processing, the recording control unit 56 determines whether or not the power of the vehicle is turned on based on the signal level of the IG signal or ACC signal input to the video recording device 30 . If the determination at step 100 is negative, step 100 is repeated until the determination is affirmative. When the power of the vehicle is turned on, the determination in step 100 is affirmative and the process proceeds to step 102 .

At step 102 , the determination unit 54 acquires information about the driver, that is, the driver sitting in the driver's seat of the vehicle, from the driver identification sensor 16 . In step 104, the determination unit 54 compares the information on the driver acquired in step 102 with the owner information 48 registered in advance in the storage unit 36, thereby determining whether the driver of the vehicle has been registered in advance. It is determined whether or not the person (owner of own vehicle) is the person (owner of own vehicle). Then, the determination unit 54 stores the determination result in the storage unit 36 or the like.

In step 106, the recording control unit 56 causes the camera 12 to photograph the surroundings of the own vehicle, and starts constant recording to record the video received from the camera 12 in the video recording area 50 as the overwriteable first video.

At step 108, the recording control unit 56 determines whether or not the vehicle is powered off based on the signal level of the IG signal or the ACC signal. If the determination at step 108 is negative, the process proceeds to step 110 . At step 110 , the recording control unit 56 determines whether or not the event detection sensor 14 has detected the occurrence of an event such as an accident.

If the determination in step 110 is negative, the process proceeds to step 112 . In step 112, the image output unit 60 receives an instruction from the passenger via the display unit 20 and the input unit 22 to reproduce or display or output the first image recorded in the image recording area 50 of the micro SD card 42. determine whether 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 affirmative.

When the occurrence of an event is detected by the event detection sensor 14 while the vehicle is powered on, the determination in step 110 is affirmative, and the process proceeds to step 114 . In step 114, the recording control unit 56 protects the video for a predetermined period of time before and after the event occurrence timing detected by the event detection sensor 14 from being overwritten by constant recording, and protects the video on the micro SD card 42 as a second video that cannot be overwritten. Record in the video recording area 50 . After the processing of step 114 is performed, the processing returns to step 108 .

In this way, while the vehicle is powered on, every time the event detection sensor 14 detects the occurrence of an event, the image captured by the camera 12 is stored in the micro SD card 42 as the second image that cannot be overwritten. It is recorded and saved in the video recording area 50 . This second image can be used as an evidence image or the like when an event such as an accident occurs.

Further, when the reproduction display or output of the first image is instructed while the power of the host vehicle is on, the determination in step 112 is affirmative, and the process proceeds to step 116 . In step 116, the image output unit 60 causes the display unit 20 to reproduce and display the first image or outputs the first image to the USB memory 26 (extraction of the first image) according to an instruction from the passenger. ). After the processing of step 116 is performed, the process returns to step 108 .

Also, when the vehicle is powered off, the determination in step 108 is affirmative and the process proceeds to step 118 . At step 118, the recording control unit 56 determines whether or not the vehicle is powered on based on the signal level of the IG signal or the ACC signal. If the determination at step 118 is negative, the process proceeds to step 120 .

In step 120, the recording control unit 56 determines whether or not the event detection sensor 14 has detected the occurrence of a parking event such as a hit-and-run event with respect to the own vehicle. If the determination in step 120 is also negative, the process returns to step 118, and steps 118 and 120 are repeated until either determination is affirmative.

When the occurrence of an event is detected by the event detection sensor 14 while the power of the host vehicle is off (when a parking event occurs), the determination in step 120 is affirmative, and the process proceeds to step 122 . In step 122 , the recording control unit 56 supplies power supplied from the positive terminal +B of the battery to the camera 12 to turn on the camera 12 and start the camera 12 .

In the next step 124, the recording control unit 56 protects the video captured by the camera 12 for a predetermined period of time after the occurrence of the parking event from being overwritten by the constant recording, and sets it as a second video that cannot be overwritten. The video recording area 50 of the SD card 42 is recorded. After the processing of step 124 is performed, the camera 12 is turned off and the process returns to step 118 .

In this way, while the power of the host vehicle is off, the camera 12 is activated each time the occurrence of a parking event is detected by the event detection sensor 14, and the image captured by the camera 12 is stored in the second non-overwriteable image. is recorded and stored in the video recording area 50 of the micro SD card 42 as the video of the. This second image can be used as an evidence image or the like when a parking event such as a hit-and-run event occurs during parking.

Also, when the vehicle is powered on, the determination in step 118 is affirmative and the process proceeds to step 126 . At step 126, the deleting unit 58 determines whether or not the driver of the own vehicle was determined to be a pre-registered person at step 104 executed when the power of the own vehicle was last turned on.

If the determination in step 126 is affirmative, the driver at the time when the vehicle was powered on last time was a pre-registered person (owner of the vehicle). There are no privacy concerns regarding the video. Therefore, when the determination in step 126 is affirmative, the process returns to step 102 and the processes after step 102 are performed.

On the other hand, if the determination in step 126 is negative, the driver of the vehicle at the time the vehicle was powered on last time was a guest, so the first image recorded in the image recording area 50 can be accessed by others. Leaving it in the room may lead to an invasion of privacy for the guest. Therefore, if the determination at step 126 is negative, the process proceeds to step 128 . Then, in step 128, the deletion unit 58 deletes the continuously recorded video (first video) recorded in the video recording area 50 from the previous power-on of the vehicle to the current power-on of the vehicle. Delete from the recording area 50 . After performing the process of step 128, the process returns to step 102, and the processes after step 102 are performed.
