Claim 14:
15. A method of controlling an ophthalmic apparatus including an optical coherence tomography (OCT) optical system that applies an OCT scan to an anterior segment of an eye, an image constructing unit that constructs an image based on data acquired by the OCT scan, and a movement mechanism that moves the OCT optical system, the method comprising:
detecting an artifact along an A-scan direction by analyzing the image constructed by the image constructing unit;
performing control of the movement mechanism based on the artifact detected;
detecting a corneal image by analyzing the image constructed by the image constructing unit;
judging whether an intersection of the artifact detected and the corneal image detected is located within a predetermined area in an image frame;
calculating an image quality evaluation value of the image constructed by the image constructing unit; and
performing control of the OCT optical system to apply an OCT scan of a predetermined pattern to the anterior segment, if the intersection is judged to be located within the predetermined area and the image quality evaluation value calculated is equal to or greater than a predetermined threshold.
