An image display device capable of reducing the burden on a passenger and reducing the occurrence of motion sickness, by giving the passenger, through a visual sense, perception (visually induced self-motion perception) of his/her own body moving while viewing an image of a TV and the like in a vehicle, and thus by matching visual information to vestibular information obtained from the motion of the vehicle, particularly to a sense of rotation and somatosensory information which are detected by his/her semicircular canals, is provided. The image display device includes: a behavior detection section (101) for detecting a behavior of a vehicle; a background image generation section (102) for generating a background image based on the behavior detected by the behavior detection section (101); an image generation section (103) for generating an image; an image transformation section (104) for, based on the behavior detected by the behavior detection section (101), transforming the image generated by the image generation section (103); a composition section (105) for making a composite image of the background image generated by the background image generation section (102) and the image transformed by the image transformation section (104); and a display section (106) for displaying the composite image made by the composition section (105).
