In an image processing device 300: a sign detection unit 303 detects a sign from an image; a sign distance calculating unit 307 calculates a distance D1 between a vehicle and the sign in the optical axis direction of an image pick-up device 100 and a distance D2 between the vehicle and the sign in the direction that crosses at right angles with the optical axis direction, based on the angle of coverage of the image pick-up device 100, the resolution of the image, the position and the size of the sign within the image, and the actual size of the sign; and a sign position estimating unit 309 estimates the position in which the sign is installed, based on the direction in which the vehicle progresses and the position of the vehicle at the time when the image is taken, and the distances D1 and D2.
