A drive recorder (1) calculates relative speed to objects (4, 5) from the time-series images acquired by stereo cameras (11, 12), and gives trigger to the recording section to start recording so as to record the time-series images on a recording section in response to the calculated relative speed, or applies marking to the time-series images which are always recorded by the recording section. Hence, the drive recorder (1) with this configuration detects the relative speed from the time-series images to perform the determination of the trigger or the marking, thus making it possible to reduce malfunction and perform more proper trigger or marking in comparison to the determination using a general acceleration sensor. |
