1. A left object detection device for detecting an object left behind in a monitoring target area, comprising:
an acquisition section which acquires an image of the area from an image pickup device for picking up an image of the monitoring target area;
a processing section, upon detection of the object which has been kept static for a given time period as an article from the image acquired by the acquisition section, the processing section starting a timer for counting time from detection of the article, determining whether or not a person who owned the article matches a person in the image acquired by the acquisition section, stopping the timer upon determination that they match, and not stopping the timer upon determination that they do not match; and
an output section which outputs in accordance with a result of the processing section, wherein:
the processing section determines whether or not the timer counts in excess of a predetermined time period;
upon determination made by the processing section that the timer counts in excess of the predetermined time period, the output section outputs an existence of the left object,
the processing section regularly receives information about an act of leaving behind from an external system, and sets the predetermined time period in accordance with the received information, and
upon reception of information indicating a vehicle operation interval from the external system, the processing section sets the predetermined time period to be longer as the operation interval of the received information becomes longer.
