Abstract

A drive recorder operation system includes a drive recorder and an operation server. The drive recorder generates index information respectively corresponding to a plurality of video files, sends the index information to the operation server, and prohibits a video file from being overwritten based on an overwrite prohibition command from the operation server. The operation server receives an instruction designating index information and sends an overwrite prohibition command including the designated index information to the drive recorder.

Claims

1. A drive recorder operation system comprising:

a drive recorder that captures images of a neighborhood of a vehicle in time sequence and that generates and records a plurality of video files; and

an operation server that is communicably connected to the drive recorder, wherein

the drive recorder generates index information respectively corresponding to the plurality of video files, sends the index information to the operation server,

the operation server receives an instruction designating arbitrary index information and sends an overwrite prohibition command including the designated index information to the drive recorder, and

the drive recorder prohibits a video file from being overwritten based on the overwrite prohibition command from the operation server.

2. The drive recorder operation system according to claim 1, wherein

the index information includes a location, date, and time.

3. The drive recorder operation system according to claim 1, wherein

the operation server acquires the index information from a plurality of drive recorders and prohibits a video file from being overwritten on the plurality of drive recorders.

4. A drive recorder comprising:

an imaging unit that captures images of a neighborhood of a vehicle in time sequence;

a recording medium that adds index information including corresponding location, date, and time to a plurality of video files generated and saves the video files;

an index information processing unit that sends the index information to an operation server that is communicably connected; and

an overwrite prohibition processing unit that prohibits a video file from being overwritten based on an overwrite prohibition command acquired from the operation server and including the index information.

5. An operation method comprising:

capturing images of a neighborhood of a vehicle in time sequence;

adding index information including corresponding location, date, and time to a plurality of video files generated and saving the video files;

sending the index information to an operation server that is communicably connected; and

prohibiting a video file from being overwritten based on an overwrite prohibition command acquired from the operation server and including the index information.

6. A non-transitory recording medium encoded with a program,

the program comprising computer-implemented modules including:

a module that capturing images of a neighborhood of a vehicle in time sequence;

a module that adds index information including corresponding location, date, and time to a plurality of video files generated and saves the video files;

a module that sends the index information to an operation server that is communicably connected; and

a module that prohibits a video file from being overwritten based on an overwrite prohibition command acquired from the operation server and including the index information.
