A moving-object counter apparatus includes a first captured-image acquisition unit, a moving-object moving-path specifying unit, a virtual-line setting unit, and a first moving-object counter unit. The first captured-image acquisition unit acquires multiple images captured at respective times different from each other by a first imaging apparatus capturing images of a predetermined region. The moving-object moving-path specifying unit specifies, on the basis of the acquired images, one or more moving paths along which one or more respective moving objects have moved in the predetermined region. The virtual-line setting unit sets a virtual line on the basis of the specified one or more moving paths. The first moving-object counter unit counts, by counting one or more moving paths that cross the set virtual line among the specified one or more moving paths, one or more moving objects that have passed through the predetermined position.
