摘要： 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.

摘要： A method for moving a sledge disposed thereon an optical pickup head of an optical disc drive is provided for controlling the motion of the sledge relative to an optical disc loaded. The optical disc drive further includes a sledge motor. At first, the sledge motor drives the sledge to move toward the center of the optical disc. At the same time, the tracks crossed by the optical pickup head are detected and counted according to a tracking error signal generated by the optical pickup head. When the count or an increment in the count within a specific period is not larger than a predetermined value or the tracking error signal is undetectable, the optical disc drive immediately stops the sledge motor from driving the sledge. The monitoring mechanism can avoid undesired impact and noises of the sledge.
