Patent ID: 6940473

Claim:
A three-dimensional representation method which generates a three-dimensional image by arranging a plurality of image planes at different depth positions for each of a left eye and a right eye of an observer and by displaying two-dimensional images on the plurality of image planes for each of the left and right eyes of the observer, the three-dimensional representation method comprising the steps of: generating two-dimensional images in which an object to be presented is projected from a point on a line passing through the left and right eyes of the observer onto the plurality of image planes; changing brightness levels of the generated two-dimensional images individually for each image plane for the left eye and for the right eye of the observer; and displaying the generated two-dimensional images on the plurality of image planes for the left eye and for right eye of the observer, wherein, when the object to be presented is displayed at a depth position close to the observer, the brightness levels of the two-dimensional images displayed on those image planes of the plurality of image planes which are close to the observer are raised and the brightness levels of the two-dimensional images displayed on the image planes remote from the observer are lowered, and wherein, when the object to be presented is displayed at a depth position remote from the observer, the brightness levels of the two-dimensional images displayed on those image planes of the plurality of image planes which are close to the observer are lowered and the brightness levels of the two-dimensional images displayed on the image planes remote from the observer are raised.
