Abstract: A server apparatus (information processing apparatus) includes: an image acquisition unit configured to acquire an image captured by a camera (imaging device); a person detection unit configured to detect a person from the image acquired by the image acquisition unit; an object detection unit (abnormality detection unit) configured to detect an object separated from the person detected by the person detection unit; a distance calculation unit configured to calculate a distance between the person detected by the person detection unit and the object detected by the object detection unit; and a lost property determination unit configured to determine that, when the distance calculated by the distance calculation unit is equal to or greater than a threshold over a predetermined time or longer, the object is lost property.

Abstract: A work management apparatus includes a first detecting unit, a second detecting unit, a third detecting unit, and an information acquiring unit. The first detecting unit detects that work was executed in a work area. The second detecting unit detects that the work in the work area ended. The third detecting unit detects that a hand of an operator entered an article area where an article relating to the work is placed. The information acquiring unit acquires information relating to the work in the work area if, from when the third detecting unit detects that the hand of the operator entered the article area until when the second detecting unit detects that the work in the work area ended, the first detecting unit detects that the work was executed in the work area.
