Abstract
A three-dimensional sense adjusting unit displays three-dimensional images to a user. If a displayed reaches a limit of parallax, the user responds to the three-dimensional sense adjusting unit. According to acquired appropriate parallax information, a parallax control unit generates parallax images to realize the appropriate parallax in the subsequent stereo display. The control of parallaxes is realized by optimally setting camera parameters by going back to three-dimensional data. Functions to realize the appropriate parallax are made into and presented by a library.
Claims8
A three-dimensional image displaying apparatus comprising:
- a display unit configured to display to one or more users at least one parallax range among multiple parallax ranges of a parallax between or among two-dimensional viewpoint images corresponding respectively to right and left eyes of the one or more users when a three-dimensional image perceived by the one or more users is displayed, the at least one parallax range being displayed for a user selection, each parallax amount range having front and back boundaries for the three-dimensional image perceived by the one or more users, the front boundary being a limit up to where the three-dimensional image appears to be maximally close to the one or more users and the back boundary being a limit up to where the three-dimensional image appears to be maximally distant from the one or more users;
- and
- a control unit configured to adjust the parallax between or among the two-dimensional viewpoint images within a selected parallax range.
A three-dimensional image processing apparatus comprising:
- a display unit configured to display to one or more users at least one parallax range among multiple parallax ranges of a parallax between or among two-dimensional viewpoint images corresponding respectively to right and left eyes of the one or more users when a three-dimensional image perceived by the one or more users is displayed, the at least one parallax range being displayed for a user selection, each parallax amount range having front and back boundaries for the three-dimensional image perceived by the one or more users, the front boundary being a limit up to where the three-dimensional image appears to be maximally close to the one or more users and the back boundary being a limit up to where the three-dimensional image appears to be maximally distant from the one or more users;
- and
- a control unit configured to adjust the parallax between or among the two-dimensional viewpoint images within a selected parallax range.
A three-dimensional image processing method comprising the steps of:
- displaying to one or more users at least one parallax range among multiple parallax ranges of a parallax between or among two-dimensional viewpoint images corresponding respectively to right and left eyes of the one or more users when a three-dimensional image perceived by the one or more users is displayed, the at least one parallax range being displayed for a user selection, each parallax amount range having front and back boundaries for the three-dimensional image perceived by the one or more users, the front boundary being a limit up to where the three-dimensional image appears to be maximally close to the one or more users and the back boundary being a limit up to where the three-dimensional image appears to be maximally distant from the one or more users;
- and
- adjusting the parallax between or among the two-dimensional viewpoint images within a selected parallax range.
A non-transitory tangible computer-readable medium having a program, when executed, controlling a computer to perform the steps of:
- displaying to one or more users at least one parallax range among multiple parallax ranges of a parallax between or among two-dimensional viewpoint images corresponding respectively to right and left eyes of the one or more users when a three-dimensional image perceived by the one or more users is displayed, the at least one parallax range being displayed for a user selection, each parallax amount range having front and back boundaries for the three-dimensional image perceived by the one or more users, the front boundary being a limit up to where the three-dimensional image appears to be maximally close to the one or more users and the back boundary being a limit up to where the three-dimensional image appears to be maximally distant from the one or more users;
- and
- adjusting the parallax between or among the two-dimensional viewpoint images within a selected parallax range.
