Abstract:
A drive recorder for recording video information received from an image capturing unit on a recording medium includes an acceleration sensor which outputs acceleration information representing an acceleration applied to a vehicle, and a control unit which, determines that a recording condition holds and records video information captured for a first predetermined period of time before the occurrence of the recording condition and video information captured for a second predetermined period of time after the occurrence of the recording condition on the recording medium when the acceleration information equals or exceeds a threshold, wherein after the recording condition holds, the control unit does not record newly captured video information on the recording medium when the acceleration information again becomes equal to or exceeds the threshold in less than a third predetermined period of time which is shorter than the second predetermined period of time.
