Abstract
An image observation apparatus is constructed to project image information displayed on an image display device for displaying the image information, onto a retina of an observing eye by a display optical system, thereby permitting an observer to observe the image information, and to perform control to change a position of an incident beam onto the entrance pupil plane of the observing eye. The apparatus is arranged to detect the position of the observer's pupil and change the position of the incident beam onto the entrance pupil plane of the observing eye, based on the result of the detection.
Claims23
An image observation apparatus comprising image display means for displaying a plurality of parallax images, and a display optical system for guiding light from the image display means to an observing eye of an observer, said image observation apparatus having means for spatially dividing an exit pupil of the display optical system into a plurality of regions, and being constructed to substantially align a position of the exit pupil of the display optical system with a position of an entrance pupil of the observing eye, cause parallax images corresponding to the respective regions to be incident on the observing eye, and thereby cause a plurality of parallax images to be incident on the single eye of the observer,
- wherein an area of a region in the outermost periphery out of the plurality of regions in the divided exit pupil is greater than those of the regions except for that in the outermost periphery.
An image observation apparatus comprising image display means for displaying a plurality of parallax images, and a display optical system for guiding light from the image display means to an observing eye of an observer, said image observation apparatus having means for spatially dividing an exit pupil of the display optical system into a plurality of regions, and being constructed to substantially align a position of the exit pupil of the display optical system with a position of an entrance pupil of the observing eye, cause parallax images corresponding to the respective regions to be incident on the observing eye, and thereby cause a plurality of parallax images to be incident on the single eye of the observer,
- wherein a size of the exit pupil of the display optical system is larger than size of the entrance pupil of the observing eye and a size of a beam from the image display means at the position of the entrance pupil of the observing eye is substantially equal to or smaller than the size of the entrance pupil of the observing eye, said image observation apparatus comprising control means to change a position of the beam from the image display means at the position of the entrance pupil of the observing eye to cause plural parallax images corresponding to respective regions of the exit pupil to be incident on the single eye of the observer.
An image observation apparatus comprising:
- image display means for displaying a plurality of parallax images;
- a display optical system including an exit pupil;
- means for spatially dividing the exit pupil of display optical system into a plurality of regions, said display optical system guiding the parallax images displayed on said image display means to each of the plurality of regions;
- and
- control means for guiding light of the plurality of parallax images into the plurality of regions,
- wherein an area of a region in the outermost periphery out of the plurality of regions in the divided exit pupil is greater than an area of regions except for a region in the outermost periphery.
An image observation apparatus comprising:
- image display means for displaying a plurality of parallax images;
- a display optical system including an exit pupil;
- means for spatially dividing the exit pupil of the display optical system into a plurality of divided regions having an area less than an area of an entrance pupil of an observing eye, said display optical system guiding the parallax images displayed on said image display means to each of the plurality of regions, and
- control means for guiding light of the plurality of parallax images into each corresponding area in the plurality of the divided regions;
- wherein a size of the exit pupil of said display optical system is greater than a size of the entrance pupil of the observing eye,
- and wherein said control means guides light of the parallax images into the plurality of regions selected from the plurality of the divided regions according to a position of the entrance pupil of the observing eye to cause plural parallax images corresponding to respective regions of the exit pupil to be incident on a single eye of the observer.
