Abstract: An optical module which includes a housing having a placing portion and an optical input-output portion facing an optical input-output surface of a ferrule; a first fixing portion for fixing the ferrule to the housing in the direction of the Z-axis perpendicular to the placing portion; and a second fixing portion for fixing the ferrule to the housing in the direction of the Y-axis perpendicular to the optical input-output surface, wherein the second fixing portion can change states from the first state to the second state; the first fixing portion fixes the ferrule in the direction of the Z-axis, and does not fix the ferrule in the Z-axis direction when the first fixing portion is at a second position; and the first fixing portion moves from the second position to the first position when the second fixing portion changes its state to a specific state.

Abstract: A gesture recognition system includes an image capturing device, a memory unit and a processing unit. The image capturing device includes a zoom lens and captures an image frame with a focus length. The memory unit previously saves a lookup table of depths versus sharpness associated with at least one the focus length of the zoom lens. The processing unit is configured to calculate a current sharpness value of at least one object image in the image frame and to obtain a current depth of the object image according to the lookup table.
