Abstract
A scan area setting unit of an exemplary ophthalmic apparatus sets a scan area in a region passing through an iris outer edge. A first scan controller controls an OCT optical system to apply an OCT scan to the scan area. An image quality evaluating unit calculates an image quality evaluation value of an image from the OCT scan. A corner angle image detecting unit analyzes the image to detect a corner angle image. A position judging unit judges whether the corner angle image is located within a first area in an image frame. A second scan controller controls the OCT optical system to apply an OCT scan of a predetermined pattern to the anterior segment, if the image quality evaluation value is equal to or greater than a threshold and the corner angle image is located within the first area.
