摘要

PROBLEM TO BE SOLVED: To suppress occurrence of motion sickness of an occupant.SOLUTION: A head rotation axis estimation part 22 estimates a rotation axis of a head on the basis of a posture of the head of a vehicle occupant who watches an image displayed on an image display device 40 installed on the vehicle. A head rotation axis change estimation part 24 estimates a change in the rotation axis of the head on the basis of a time sequence of the rotation axis of the head estimated by the head rotation axis estimation part 22. When the change in the rotation axis of the head estimated by the head rotation axis change estimation part 24 is equal to or larger than the predetermined threshold, an image display control part 30 controls the image display device 40 by at least one of changing a display position of an image and rotating a display of an image to be controlled to restrain the posture change of the occupant's head.
