An image recording apparatus for recording images sensed by at least two cameras
attached to a vehicle, has a first camera which is arranged to have an image sensing
direction agreeing with a first direction of a vehicle, a second camera which is
arranged at a position separated a known distance r from the first camera to have
an image sensing direction agreeing with a second direction about 180 different
from the first direction, and a unit for, when the vehicle travels in the first
direction, recording first image data sensed by the first camera and second image
data sensed by the second camera a time duration later corresponding to the known
distance, in association with each other.
