Abstract
A position identifying apparatus includes multiple image capturers, an accumulating unit, a deriving unit, and an identifying unit. The image capturers capture images of predetermined image capturing ranges. The accumulating unit accumulates in time series movement track information of a person included in the images captured by the image capturers. The deriving unit derives, using the movement track information accumulated in the accumulating unit, for each image position in an image captured by any one of the image capturers, a probability that, at a same time as a time at which a person is image-captured at the image position, a person is image-captured at each image position in an image captured by another one of the image capturers. The identifying unit identifies, from the probability derived by the deriving unit, an image position common to the images captured by the image capturers.
