<P>PROBLEM TO BE SOLVED: To accurately detect sound of a detection object from sound data without limiting a drive recorder (DR: Drive Recorder). <P>SOLUTION: A sound detection device 100 detects a set of partial sound data whose characteristics of vehicle shake out of sound data 110a are similar to each other as a similar sound data group 110c and calculates a background noise value to be an index of sound intensity value of the background noise based on the similar sound data group 110c. Further, a sound detection section 120e detects the sound data for the detection from the sound data 110a based on the characteristics of the sound for the detection, and corrects the detection result using the background noise value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
