Ophthalmic apparatus, method of controlling same, and recording medium

Abstract

An ophthalmic apparatus includes a light source, an illumination optical system, an optical scanner, an imaging optical system, and a controller. The illumination optical system is configured to generate slit-shaped illumination light using light from the light source. The optical scanner is configured to deflect the illumination light to guide the illumination light to a fundus of a subject's eye. The imaging optical system is configured to guide returning light of the illumination light from the fundus to an image sensor, the image sensor capturing light receiving result of a region on a light receiving surface corresponding to an illumination region of the illumination light on the fundus, the illumination region being moved by the optical scanner. The controller is configured to control a deflection angle of the illumination light of the optical scanner. The optical scanner is configured to output a scanner position signal corresponding to the deflection angle of the illumination light. The image sensor is configured to start capturing the light receiving result of the returning light in synchronization with the scanner position signal.
