A left object detection device for detecting an object left behind in a monitoring target area includes 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, and an output section which outputs in accordance with a result of the 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 starts a timer for counting time from detection of the article, determines whether or not a person who owned the article matches a person in the image acquired by the acquisition section, stops the timer upon determination that they match, and does not stop the timer upon determination that they do not match. 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.
