DUAL PRISM OPTICAL IMAGE STABILIZATION
A camera includes an image sensor, a lens configured to focus light to the image sensor, a first prism, a first actuator configured to rotate the first prism about a first axis, a second prism, and a second actuator configured to rotate the second prism about a second axis substantially perpendicular to the first axis. The camera also includes a controller configured to perform optical image stabilization (OIS) by independently controlling the first actuator to rotate the first prism about the first axis and controlling the second actuator to rotate the second prism about the second axis.
CAMERA ACTUATOR AND CAMERA MODULE COMPRISING SAME
A camera actuator disclosed to an embodiment includes a first housing, a prism unit disposed in the first housing, and a first driving portion tilting the prism unit in a first axis or a second axis, the first driving portion include a first magnet disposed on a region corresponding to a first outer surface of the prism unit; a second magnet disposed on a region corresponding to a second outer surface opposite to the first outer surface of the prism unit; and a third magnet disposed on a region corresponding to a third outer surface disposed between the first and second outer surfaces of the prism unit, the first and second magnets are spaced apart in a first direction, a length of the third magnet in the first direction may be 50% to 98% of a distance between the first and second magnets in the first direction.
