A camera module with no PCB that instead has a lens actuator/housing that has circuitry on a bottom surface thereof for direct electrical connection to a mobile electronic device. The housing further has a recess formed in the bottom surface thereof to receive an image sensor. The circuitry is three-dimensional in that it includes a first set of contact pads on one planar surface for connection to the mobile electronic device, a second set of contact pads on a planar surface within the recess for connection to the image sensor, and conductive traces that connect each of the contact pads of the first set with an associated one of the contact pads of the second set by having the trace follow a path from the first planar surface, along a intersecting third planar surface to the second planar surface.

Autofocus camera module packaging with circuitry-integrated actuator system

A camera module with a lens barrel containing a lens, and a lens carrier that slidably receives the lens barrel. Each of the exterior surface of the lens barrel and the interior surface of the lens carrier include a seating surface formed thereon. One of the exterior surface of the lens barrel and the interior surface of the lens carrier include a plurality of protrusions for controlling the relative position of the lens barrel and the lens carrier. The other of the exterior surface of the lens barrel and the interior surface of the lens carrier include a plurality of channels that are sized and arranged so as to slidably receive the protrusions to allow for the lens barrel to be slid into the lens carrier. The channels also each include a transverse section to allow the lens barrel to be pivoted about an optical axis of the lens barrel.

Camera module with threadless lens barrel engagement design

A camera module including a particle trap. The particle trap may be disposed in the camera module and may be operable to prevent particles from obstructing an optical path defined between a lens assembly and an image sensor. The particle trap may include a particle getter to retain particles in contact with the particle trap. The camera module may be operative to move the lens assembly so as to provide focus on the image sensor for objects at various distances from the camera module. The movement of the lens assembly may be a source of particles retained by the particle trap.

Camera module with particle trap

A camera module with a vent in a housing thereof to allow for fluid communication between an interior of the camera module and an exterior of the camera module. A micro-porous membrane filter having a pore size smaller than 10 um is employed to cover the vent so as to reduce the flow of contaminants into the camera module.

Camera module with protective air ventilation channel

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.

Auto focus-zoom actuator or camera module contamination reduction feature with integrated protective membrane

A camera module having a liquid crystal shutter that controls the time period during which the image sensor is exposed to light directed into the camera module. The shutter is located within the camera module housing, which may include EMI shielding and may include a lens actuator for moving a movable lens group. The shutter may be located before or after the movable lens group and before or after a fixed lens group that may also be included. The camera module may also include an IR filter for reducing the amount of IR light that reaches the image sensor.
