Abstract
The action camera has a housing, a lens, and an image sensor located in a light path from the lens. A filter is operable to move between first and second positions, with the first position located in the light path and the second position located out of the light path. An actuator moves the filter between the first and second positions. The actuator includes an electromagnet and a magnet. One of the electromagnet and the magnet is fixed relative to the light path, while the other of the electromagnet and the magnet is movable relative to the light path and is coupled to the filter. The magnet has poles that interact with the poles of the electromagnet. As the electromagnet is energized, the magnet rotates. The polarity of the electromagnet is reversed in order to reverse the rotation of the magnet. The camera is also provided with a light source. When the light source is activated, then the filter is moved accordingly. The actuator is small and consumes little electrical power.
