Abstract
A three-dimensional display device for displaying a three-dimensional image, including: a gaze point obtaining unit which obtains a position of a gaze point of a viewer; a fusional area determination unit which determines a fusional area where binocular fusion is allowed, based on the obtained position of the gaze point; a correction unit which corrects the three-dimensional image so as to suppress display of an object that is included in the three-dimensional image outside the fusional area; and a display unit which displays the corrected three-dimensional image.
Claims13
A three-dimensional display device for displaying a three-dimensional image, comprising:
- a gaze point obtaining unit configured to obtain a position of a gaze point of a viewer;
- a fusional area determination unit configured to determine a fusional area where binocular fusion is allowed, based on the obtained position of the gaze point;
- a correction unit configured to correct the three-dimensional image so as to suppress display of an object which is included in the three-dimensional image outside the fusional area;
- a display unit configured to display the corrected three-dimensional image;
- and
- a fusional area information storage unit configured to store fusional area information which indicates positions of a plurality of gaze points in a depth direction of the three-dimensional image and a plurality of fusional areas corresponding to the positions of the plurality of gaze points in the depth direction,
- wherein the fusional area determination unit is configured to refer to the fusional area information to determine the fusional area that corresponds to the obtained position of the gaze point.
