摘要:
A fundus camera has an image pickup element adapted to receive reflection light from an anterior ocular segment of an examinees eye and a light receiving optical system that guides the reflection light from the anterior ocular segment of the examinees eye to the image pickup element. The fundus camera is provided with a focus evaluation value acquisition unit that acquires a focus evaluation value representing an in-focus state of the light receiving optical system for the anterior ocular segment of the examinees eye on the basis of an output of the image pickup element for a specific part of the anterior ocular segment of the examinees eye and an in-focus position determination unit that determines an in-focus position of the light receiving optical system based on the focus evaluation value. With these unit, auto-focusing can be performed when imaging the anterior ocular segment.
