  • Camera module actuator
    Patent number: 11163211
    Abstract: An actuator includes a magnet, a driving coil facing the magnet, a driver, and a position calculation processor. The driver is configured to move the magnet in at least one of an optical axis direction and a direction perpendicular to the optical axis by applying a driving signal to the driving coil. The position calculation processor includes sensing coils, and is configured to calculate a position of the magnet according to inductance levels of an inductor of the sensing coils. The inductance levels vary according to movements of the magnet.
