ABSTRACT:
The position of a solid image which changes with the elapse of time is detected. The position of a virtual screen is set so that a distance from an object enters an allowable range such as to reduce a fatigue of an observer. A 2-dimensional image is formed at the set virtual screen position. A phase distribution is calculated at the hologram forming surface, thereby displaying a solid image. Even when the position of a solid image changes with the elapse of time, the fatigue of the eyes can be minimized.
