Claim:
A drive recorder for recording video information received from an image capturing unit on a recording medium, comprising: an acceleration sensor which outputs acceleration information representing acceleration applied to a vehicle; and a control unit configured to determine an occurrence of a recording condition and record video information captured for a first predetermined period of time before the occurrence of said recording condition, and record video information captured for a second predetermined period of time after the occurrence of said recording condition, on said recording medium when said acceleration information equals or exceeds a threshold, wherein after the occurrence of said recording condition, said control unit does not record newly captured video information on said recording medium when said acceleration information again becomes equal to or exceeds said threshold in less than a third predetermined period of time, which is shorter than said second predetermined period of time, and wherein after the occurrence of said recording condition, said control unit extends the length of time to record said video information on said recording medium when said acceleration information again becomes equal to or exceeds said threshold within a period of time not shorter than said third predetermined period of time but shorter than said second predetermined period of time.
