Abstract
Apparatus and method for displaying three-dimensional images with a display device. A blocking grid is positioned between a display device and a viewer, and a drive system oscillates the blocking grid in accordance with the display of a plurality of images. Each image is aligned with the grid and is structured such that each eye of the viewer sees only a displayed portion of a displayed image intended for that eye, thereby creating a three-dimensional effect.
Claims30
An apparatus for allowing the viewing of three-dimensional images using a display device displaying two-dimensional images, the apparatus comprising:
- a blocking grid positioned between the display of the display device and a viewer;
- and
- a drive system for oscillating the blocking grid in accordance with the display of a plurality of images, wherein each image is approximately aligned with the grid and each image is structured such that each eye of the viewer sees only a displayed portion of a displayed image intended for that eye, thereby creating a three-dimensional effect.
A method for providing three dimensional images using a display device capable of displaying two-dimensional images, the method comprising:
- (a) creating a plurality of composite images, wherein each composite image includes portions of two separate images, each separate image portraying the perspective of one of the eyes of a viewer;
- (b) displaying the composite images on the display device, one at a time, at a display frequency;
- and
- (c) oscillating a blocking grid which is positioned between the display of composite images and the viewer such that each eye of the viewer sees only the portions of the composite images that are intended for that eye.
A system for providing three-dimensional images, the system comprising:
- a display device capable of displaying two-dimensional images, wherein the display device is caused to display a plurality of composite images, wherein each composite image includes alternating portions of two separate images, each separate image taken from the perspective of one of the eyes of a viewer;
- and
- a blocking device positioned between the display device and the viewer, the blocking device including a grid, wherein the blocking grid is oscillated in accordance with the display of the composite images, and wherein each composite image is structured and aligned with the grid such that each eye of the viewer sees only a displayed portion of the composite images intended for that eye through spaces in the grid, thereby creating a three-dimensional effect.
