Title:
THREE-DIMENSIONAL IMAGE REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JP3255093
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accurately and rapidly reproduce a three-dimensional image the observation area of which is wide and large and to excellently observe it by controlling an interval between plural most proximate light beams passing a specified point and made incident on an observation position in accordance with the diameter of an observer's pupil in the case of reproducing and observing the three-dimensional image at the specified point.
SOLUTION: A light beam emitting direction control means 2 independently controls and emits the light beams from a light source train 1 constituted by plurally arraying light source parts 1a radiating a unidirectional light beam. A control means 101 consisting of a light beam emitting direction detection means 3 and a light source train control means 4 controls the light emitting states of plural light source parts 1a and a light beam emitting direction from the control means 2 so that the aggregation of the light beams from the control means 2 may pass the specified point in three-dimensional space in fixed unit time. In the case of reproducing the three- dimensional image at the specified point and observing it at the observation position, the control means 101 controls the interval between two most proximate light beams passing the specified point and made incident on the observation position in accordance with the diameter of the observer's pupil.
