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.

Image capturing apparatus and auto-focusing method thereof

An apparatus of auto-focusing is provided, including an outer holder, a wire set, a magnet set and an inner-holder. The magnet set is fixed at the corners inside the outer-holder. The inner-holder is a hollow cylinder surrounded by a coil. The wire set is connected to the top and the bottom ends of the outer-holder. The other end of the wire set is connected to the outer circumference of the inner-holder. Therefore, the inner-holder is a hanging moveable component, which can move vertically when the electrical current flows through the coil to achieve the object of auto-focusing.
