IMAGE DISPLAY APPARATUS

An image display apparatus has: a synthesizing device (132) for synthesizing a rear image (111B) captured by a rear imaging device (11B) for imaging rear area of a first vehicle (1) and a rear side image (111BL, 111BR) captured by a rear side imaging device (11BL, 11BR) for imaging rear side area of the first vehicle to generate a synthesized image (111C); and a display (14) for displaying the synthesized image. The synthesizing device varies a proportion of each of a rear image area and a rear side image area to the synthesized image based on velocity of the first vehicle and/or a distance between the first vehicle and a second vehicle existing at the rear of the first vehicle, wherein the rear image area and the rear side image area are areas in which the rear image and the rear side image are displayed, respectively, in the synthesized image.
