Abstract
A lens module for autofocus of a camera in passive mode includes a lens barrel containing a first lens, a second lens, a pressure sensor, an image sensor, and a processor. In the passive autofocus mode, the first lens is located at a first end of the lens barrel and moves within the lens barrel when a distance to a target object changes. The pressure sensor between the first and the second lenses senses both pulling and pushing pressures which the first lens applies. The image sensor is adjacent to an end of the lens barrel and is behind the first and second lenses. The processor can apply formulas to calculate a distance between the target object and the lens module.
