<P>PROBLEM TO BE SOLVED: To solve the problem that it is necessary to install a sensor exclusive for security countermeasures to thereby increase cost in a conventional drive recorder, and that even when an acceleration sensor or the like is used as it is, small acceleration to be generated when burglary occurs is not detectable, and even when burglary occurs, it is not possible to record a video by the driver recorder as a result. <P>SOLUTION: The drive recorder includes a control unit for comparing an output signal from an acceleration sensor with a preliminarily set determination threshold, and for making a storage unit store a captured image, based on the comparison results. The control unit is configured to change the determination threshold of the acceleration sensor based on the change of a signal for detecting the parking state of a vehicle. <P>COPYRIGHT: (C)2010,JPO&INPIT |
