Abstract:
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.
