Regarding update of the distance information, the controller calculates information on movement of an object included in the image information. When determining that the object is not moving, the controller updates the currently set distance information with newly acquired distance information, while when determining that the object is moving, the controller maintains the currently set distance information as it is without updating the currently set distance information. | 12-03-2015 |
