Abstract
It is an object of the present invention to display unnaturalness-free images without showing an observer repetitive images in accordance with the observer's viewpoint. A light beam control elementlimits a viewing area of images composed of light emitted from a light source array. Here, a terminal position detection sensoror an observer position detection sensordetects a relative positional relationship between the observer's eye observing the image formed by the light emitted from the light source array, and the light source arrayand the light beam control element. Based on the positional relationship detected by these sensors, a display image control devicecontrols the light source arrayso as to change display contents of the light forming the image with the viewing area limited by the light beam control element
