Abstract
A miniature camera module comprising: a module frame comprising a surface with a conduit passing through the surface, thereby allowing light to pass through the surface via the conduit; a first blade coupled to the module frame and configured to rotate about a first axis between an open position and a closed position, wherein the first blade does not eclipse the conduit at all when in the open position and the first blade at least partially eclipses the conduit when in the closed position; a first solenoid coupled to the module frame; and a first pin coupled to the first solenoid, wherein an actuation of the first solenoid causes the first pin to rotate the first blade from the open position to the closed position. In some embodiments, the module includes additional blades, solenoids and pins.
