1. An ophthalmic apparatus comprising:
an image acquiring circuit configured to acquire an anterior segment image constructed based on data collected from an anterior segment of a subject's eye by optical coherence tomography (OCT) scanning;
a first image region identifying processor configured to identify a first image region corresponding to a predetermined part of the anterior segment by analyzing a first part of the anterior segment image acquired by the image acquiring circuit;
a second image region identifying processor configured to identify a second image region corresponding to the predetermined part based on the first image region identified by the first image region identifying processor, the second image region being inside a second part that includes the first part as a proper subset;
an analysis region setting processor configured to set an analysis region that includes the second image region identified by the second image region identifying processor; and
a third image region identifying processor configured to identify a third image region corresponding to the predetermined part by analyzing the analysis region set by the analysis region setting processor.
