Abstract

[Problem] A drive recorder is provided that enables acquisition of a desired image captured when an impact with a strength meeting a predetermined condition has been measured. [Means of Solution] In the drive recorder 1, the travel recording module 51 records captured moving-imagery data 60 captured by a camera 18 installed on a vehicle. The acceleration sensor 19 measures the acceleration of the vehicle. When it is determined that the acceleration measured by the acceleration sensor 19 is within an abnormality range, the travel recording module 51 notifies the server 4 at a predetermined time point of the time point of dangerous driving at which the acceleration within the abnormality range was measured. The travel recording module 51, when receiving from the server 4 a request for video transmission containing the time point of dangerous driving, selects, from the recorded captured moving-imagery data 60, the captured moving-imagery data 60 associated with a predetermined time period including the time point of dangerous driving contained in the request for video transmission, and transmits this data to the server.

an accident determination unit configured to determine whether the strength of the impact measured by the sensor is within a predetermined accident reference range larger than the abnormality range; and

an accident video transmission unit configured, when the accident determination unit determines that the strength of the impact measured by the sensor is within the accident reference range, to transmit to the server, without waiting for the request for video transmission, out of the captured moving-imagery data recorded by the recording unit, captured moving-imagery data associated with a predetermined time period including a time point at which the strength of the impact within the accident reference range was measured.

2. The drive recorder according to claim 1, wherein, when the abnormality determination unit determines that the strength of the impact measured by the sensor is within the abnormality range, the recording unit creates a still image associated with the time point of dangerous driving based on an image captured by the camera, and

the notification unit transmits the still image created by the recording unit together with the time point of dangerous driving.

3. The drive recorder according to claim 1, wherein, when the abnormality determination unit determines that the strength of the impact measured by the sensor is within the abnormality range, the recording unit extracts the captured moving-imagery data associated with the predetermined time period including the time point of dangerous driving from the captured moving-imagery data recorded by the recording unit, and

the requested video transmission unit transmits the captured moving-imagery data extracted by the recording unit.
