Abstract
An image capturing apparatus and an auto-focusing method thereof are provided. The method includes transmitting light beams from light sources to an eye including a cornea, a pupil, a crystalline lens, and a fundus. The light beams are transmitted to the fundus through the cornea. The light beams transmitted to the cornea form first light point images detected by an image sensor through a lens module having first and second lenses. According to the first light point images and focal adjustment data, the first lens and the light sources are moved simultaneously to focus on the cornea. The light beams are substantially intersected at the pupil and transmitted to the fundus to form second light point images detected by the image sensor through the lens module. According to the second light point images and the focal adjustment data, the first lens is moved to focus on the fundus.
