Method of observing a three-dimensional image of examinee's eye
First Claim
1. A method of observing a three-dimensional image of an examinee'"'"'s eye to be examined, including:
- obtaining a first three-dimensional image which is a three-dimensional image of an anterior segment of the examinee'"'"'s eye by an optical coherence tomography optical system for obtaining a tomographic image by guiding a measurement light to the anterior segment of the examinee'"'"'s eye;
obtaining a second three-dimensional image which is a three-dimensional image of a fundus of the examinee'"'"'s eye by the optical coherence tomography optical system for obtaining a tomographic image by guiding the measurement light to the fundus of the examinee'"'"'s eye by a timing different from a timing of obtaining the first three-dimensional image;
constructing a three-dimensional eyeball image of the examinee'"'"'s eye through image processing based on the obtained first and second three-dimensional images; and
displaying the constructed three-dimensional eyeball image on a monitor.

Abstract
A method of observing a three-dimensional image of an examinee'"'"'s eye to be examined, includes: obtaining a first three-dimensional image which is a three-dimensional image of an anterior segment of the examinee'"'"'s eye by optical coherence tomography for obtaining a tomographic image by converging a measurement light on the anterior segment of the examinee'"'"'s eye; obtaining a second three-dimensional image which is a three-dimensional image of a fundus of the examinee'"'"'s eye by optical coherence tomography for obtaining a tomographic image by converging the measurement light on the fundus of the examinee'"'"'s eye by a timing different from a timing of obtaining the first three-dimensional image; constructing a three-dimensional eyeball image of the examinee'"'"'s eye through image processing based on the obtained first and second three-dimensional images; and displaying the constructed three-dimensional eyeball image on a monitor.

17. A method of observing a three-dimensional image of an examinee'"'"'s eye to be examined, including:
-
obtaining a tomographic image of a whole eye including a region from a cornea through a fundus by an optical coherence tomography optical system having an imaging range from the cornea through the fundus; and performing at least one of a matching process of an anterior segment region in the obtained tomographic image of the whole eye and a first three-dimensional image which is a three-dimensional image of an anterior segment of the examinee'"'"'s eye obtained by the optical coherence tomography optical system, and a matching process of the fundus region in the obtained tomographic image of the whole eye and a second three-dimensional image which is a three-dimensional image of the fundus of the examinee'"'"'s eye obtained by the optical coherence tomography optical system by a timing different from a timing of obtaining the first three-dimensional image. - View Dependent Claims (18)
