  • Auto focus-zoom actuator or camera module contamination reduction feature with integrated protective membrane
    Patent number: 8545114
    Abstract: A camera module includes a lens system, an image sensor, and an actuator. The actuator is fixed relative to the image sensor, and the actuator moves the lens system relative to the image sensor to achieve focus. Components that move relative to each other result in gaps or spaces between the components, an in particular there is a gap between the lens system and the actuator. Such a gap provides a traveling path for foreign material, or particulates, to enter the camera module and reach the image sensor, or other intermediate optical components between the lens system and the image sensor. A camera contamination reduction apparatus is implemented as a protective membrane that prevents foreign material from reaching the internal optical components through the traveling path.
