Abstract
A mobile object information recording apparatus includes first and second cameras and various vehicle condition sensors for detecting mobile object information representing the status of a vehicle. An abnormal level detector detects an abnormal level of the vehicle on the basis of the acceleration detected by a 3-dimensional sensor. A data amount setting unit sets the amount of data to be stored in a file area to a value corresponding to the detected abnormal level, and memory controller stores, into the file area, mobile object information with a length of time corresponding to the determined amount of data, including periods immediately before and after the moment at which the abnormal level is detected, such as when a collision occurs, whereby the mobile object information is stored in a highly efficient fashion.
