Abstract:
1. A monitoring device comprising: a tour monitoring unit adapted to cause an image pickup unit to cyclically monitor a plurality of previously registered monitoring spots; an unmoving object monitoring unit adapted to monitor an unmoving object at the monitoring spot for a predetermined unmoving object monitoring time based on a previously captured background image before the image pickup unit is moved from the predetermined monitoring spot by said tour monitoring unit; a storage unit adapted to store an unmoving object monitoring position when said unmoving object monitoring unit starts counting the unmoving object monitoring time; a first determination unit adapted to determine whether the predetermined unmoving object monitoring time for the unmoving object elapses or not while said tour monitoring unit causes the image pickup unit to cyclically monitor a plurality of the spots; a moving unit adapted to forcibly move the image pickup unit to the unmoving object monitoring position stored in said storage unit at a predetermined timing if the image pickup unit is moved to another monitoring spot at which the unmoving object is not yet found by said tour monitoring unit when said first determination unit determines that the predetermined unmoving object monitoring time for the unmoving object elapses; and a second determination unit adapted to determine whether the unmoving object is unidentified at the unmoving object monitoring position to which the image pickup unit is moved by said moving unit, wherein the predetermined unmoving object monitoring time is longer than the tour monitoring time during which the image pickup unit cyclically monitors any one of the monitoring spots.
