    Abstract: An apparatus to perform or control obtaining or causing obtaining an image of at least a part of a surface of a sealed unit. The apparatus derives or causes to derive a representation of the at least a part of the surface from the image. The representation includes a set of values representing height levels of corresponding sections of the part of the surface. The apparatus generates or causes generating a string of characters based on the representation of the part of the surface. The string of characters includes a first portion representative of the set of height levels and a second portion generated based on a function of the representation and/or of the first portion of the string of characters. The apparatus associates or causes associating information representing the string of characters with identification information of the sealed unit.

    Abstract: 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.
