Information recording apparatus
First Claim
1. An information recording apparatus comprising:
- a storage portion configured as a ring buffer so as to endlessly store thereinto at least one of image information and sound information of the interior or exterior of a vehicle, the information being acquired by an acquisition portion,an abnormal condition detection portion configured to detect the presence of an abnormal condition of the vehicle based on a signal from a sensor configured to detect an abnormal condition,a recording portion composed of nonvolatile memory configured to record thereinto the information stored in the storage portion,a control portion configured to cause the storage portion to store thereinto the information acquired by the acquisition portion for a first time period from a detection of occurrence of the abnormal condition of the vehicle by the abnormal condition detection portion, andwhen the abnormal condition detection portion has detected the abnormal condition of the vehicle again during the first time period from the detection of occurrence of the abnormal condition of the vehicle, the control portion, having thus concluded that the abnormal condition is an actual theft, is configured to cause the storage portion to store thereinto the information acquired by the acquisition portion for a second time period that is longer than the first time period from a previous detection of occurrence of the abnormal condition of the vehicle, and is configured to cause the recording portion to record thereinto the information stored in the storage portion for the second time period, andwhen the abnormal condition is newly detected by the abnormal condition detection portion after the first time period has elapsed but before a third time period longer than the first time period elapses, the control portion is configured to cause the recording portion to record thereinto the information stored in the storage portion at a time of the previous detection of occurrence of the abnormal condition together with the information stored in the storage portion at a time of the newly detected occurrence of the abnormal condition.

Abstract
Image and sound information are acquired from a camera and a microphone and the information is stored into a second RAM for a first time period from detection of occurrence of an abnormal condition of a vehicle by a sensor. When occurrence of an abnormal condition of the vehicle has been detected by the sensor during the first time period from the detection of occurrence of an abnormal condition of the vehicle, image and sound information is acquired from the camera and the microphone and the information is stored into the second RAM for a second time period from the previous detection of occurrence of an abnormal condition of the vehicle, and the image and sound information stored into the second RAM for the second time period Tb are stored into a nonvolatile ROM.
