To easily viewably display a vehicular swept path drawn within an image.

A vehicular swept path drawing part 102a draws an estimated vehicular swept path on an image around a vehicle which is picked up by a camera 101, and an obstacle detection part 102b detects an obstacle existing in the image. In the case that a drawn running track and the obstacle overlap in the image, a vehicular swept path correction part 102c corrects the vehicular swept path so that a part of the vehicular swept path overlapped with the obstacle is distinct from the other part of the vehicular swept path which is not overlapped with it.
