Classification: CPC A  G | IPC A  G

Claim 0:
1. An ophthalmic apparatus comprising:
an optical coherence tomography (OCT) optical system configured to apply an OCT scan to an anterior segment of an eye;
processing circuitry configured as an image constructing unit configured to construct an image based on data acquired by the OCT scan;
the processing circuitry further configured as an artifact detecting unit configured to analyze the image constructed by the image constructing unit to detect an artifact along an A-scan direction;
a movement mechanism including an actuator and configured to move the OCT optical system;
the processing circuitry further configured as a first movement controller configured to perform control of the movement mechanism based on the artifact detected by the artifact detecting unit;
the processing circuitry further configured as a conical image detecting unit configured to analyze the image constructed by the image constructing unit to detect conical image;
the processing circuitry further configured as a position judging unit configured to judge whether an intersection of the artifact detected by the artifact detecting unit and the corneal image detected by the corneal image detecting unit is located within a predetermined area in an image frame;
the processing circuitry further configured as an image quality evaluating unit configured to calculate an image quality evaluation value of the image constructed by the image constructing unit; and
the processing circuitry further configured as a scan controller configured to perform control of the OCT optical system to apply an OCT scan of a predetermined pattern to the anterior segment, if the position judging unit judges that the intersection is located within the predetermined area and the image quality evaluation value calculated by the image quality evaluating unit is equal to or greater than a predetermined threshold.
