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).
