Abstract
A camera module includes a lens assembly, a lens barrel, an image sensor, a hollow holder receiving the lens barrel and the image sensor, and a thermally deformable member. The lens assembly defines a first focal length with a first focus point at a first temperature and a second focal length with a second focus point at a second temperature on an optical axis associated therewith. The thermally deformable member has one end attached to the lens barrel and an opposite end attached to the holder. The thermally deformable member comprises a first sheet and a second sheet. Wherein at the second temperature, the second sheet bends toward the first sheet thereby moving the second focus point toward the first focus point and the image plane of the lens assembly with the second focal length toward the image sensor.
