Disclosed is a person-judging device comprising: an obstruction storage unit which stores information indicating the area of an obstruction on an image based on a video signal from an external camera, the obstruction being extracted from the image; a head portion range calculation means which, when a portion of an object extracted from the image is hidden by the obstruction, assumes that the potential range of grounding points where the object touches a reference face on the image is the area is the area of an obstruction which is stored in the obstruction storage unit, and which, based on the assumed range and the correlation between the height of a person and the size and position of the head portion that were previously provided, calculates the potential range of the head portion on the image when the region farthest from the grounding point of the object is assumed to be the head portion of the person; and a head portion detection means that judges whether an area having a shape that corresponds to the head portion exists in the calculated range of the head portion. |
