PROBLEM TO BE SOLVED: To accurately detect a person area by correcting a part of a human body shielded by masking or the like. SOLUTION: The person area detection device for detecting an image area of a person included in a taken frame includes: an imaging means which images the frame to obtain time-series images; a height estimation means which estimates the height of a person to be tracked from each of the time-series images obtained by the imaging means; a shielding state determination means which determines whether the image area of the person is partially shielded by masking; and a person area estimation means which estimates, when the image area of the person is partially shielded by masking, a person area in the image, including the part shielded by masking, based on position information for the head or foot end of the person obtained by the height estimation means and a vanishing point specified from the image.
