Abstract
A person-judging device comprises: an obstruction storage which stores information indicating an area of an obstruction which is extracted from an image based on a video signal from an external camera, the obstruction being extracted from the image; head portion range calculation means which, when a portion of an object which is extracted from the image is hidden by the obstruction, assumes that a potential range of grounding points where the object touches a reference face on the image is the area of the obstruction which is stored in the obstruction storage, 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 are previously provided, calculates the potential range of the head portion on the image by assuming that a portion farthest from the grounding points of the object is the head portion of the person; and head portion detection means that judges whether an area including a shape corresponding to the head portion exists in the calculated range of the head portion.
