Abstract
A stay duration measurement device for measuring a stay duration in a measurement area for each moving object, includes: a movement line obtaining unit that obtains a movement line of each moving object detected from images including the measurement area; a movement line assessment unit that determines whether the movement line obtained by the movement line obtaining unit includes a missing part in the measurement area; and a stay duration obtaining unit that, in a case where it is determined by the movement line assessment unit that the movement line of a moving object of interest includes a missing part in the measurement area, obtains a stay duration compensated for the missing part based on a time period(s) required for movement(s) of one or more other moving objects in the measurement area.
