Abstract
A disclosed example camera module includes a substrate, an integrated circuit image capture device (ICD) mounted on the substrate, the image capture device having an array of light sensors on its top surface, a first lens unit rigidly fixed to the top surface of the image capture device, a second lens unit, and a lens actuator mounted on the substrate. The lens actuator adjustably supports the second lens unit over the first lens unit. The first lens unit includes a stacked plurality of lenses. Optionally, the second lens unit also includes a stacked plurality of lenses. Movement of the second lens unit with respect to the first lens unit provides a focus and/or zoom function.
