Camera module, and position detector and position detection method used in the camera module

摘要

Provided is a camera module including: a lens barrel including at least one lens group; a moving frame that includes the lens barrel, is movable in a first direction and in a second direction that is perpendicular to the first direction, and includes first and second magnets that are disposed on two sides in the first direction; a fixed frame that movably supports the moving frame and includes first and second magnetic sensors that are spaced apart from each other in the first direction to respectively correspond to the first and second magnets; and a position information generating unit that generates position information of the first and second magnets in the second direction based on a first detection signal detected by the first magnetic sensor and a second detection signal detected by the second magnetic sensor.

1. A camera module comprising:
a lens barrel including at least one lens group; a moving frame that mounts the lens barrel, is movable in a first direction and in a second direction that crosses the first direction, and includes first and second magnets that are disposed on two sides in the first direction; a fixed frame that movably supports the moving frame and includes first and second magnetic sensors that are spaced apart from each other in the first direction to respectively correspond to the first and second magnets; and a position information generating unit that generates position information of the first and second magnets in the second direction based on a first detection signal detected by the first magnetic sensor and a second detection signal detected by the second magnetic sensor.
