Enabled is to detect overlying objects distinctively even if a still object is overlaid by another still object or a moving object. A data processing device comprises first means for detecting an object area on a plurality of time-series continuous input images, second means for detecting a stationary area contained in the object area, from the plural input images, third means for storing the information of the stationary area as the time-series background information, and fourth means for comparing the time-series background information and the object area thereby to detect each object contained in that object area. |
