Abstract: This disclosure describes a method to calibrate a position of an optical image stabilization (OIS) lensing element 308 based on an electric current reading of one or more areas of a mobile imaging device 200. The position is a deviation from a center position, where the OIS lensing element 308 is not influenced by a force. A coupling compensation coefficient is generated based on the electric current reading. A derived value for the position is adjusted based on the coupling compensation coefficient. A scaling sensitivity coefficient is generated based on the electric current reading. The derived value for the position is further adjusted based on the scaling sensitivity coefficient. The coupling compensation coefficient and the scaling sensitivity coefficient are further based on maximum and minimum values for the Hall Effect sensor at the temperature reading and a calibration temperature.

Abstract: This disclosure describes a method to calibrate a position of an optical image stabilization (OIS) lensing element 308 based on a temperature reading. The temperature reading is of one or more sensors, such as a Hall Effect sensor, and the position is a deviation from a center position, which is the position of the OIS lensing element 308 when it is not influenced by a force. A center drift coefficient is generated based on the temperature reading. A derived value for the position is adjusted based on the center drift coefficient. Additionally, a scaling sensitivity coefficient is generated based on the temperature reading. The adjusting of the derived value for the position is further based on the scaling sensitivity coefficient. The center drift coefficient and the scaling sensitivity coefficient are further based on maximum and minimum values for the Hall Effect sensor at the temperature reading and a calibration temperature.

Abstract: An electromagnetic driving device defined with an X axis, a Y axis and a Z axis includes a casing, a frame, a driven object (e.g., a lens module), an anti-tilt mechanism and an electromagnetic driving module. The electromagnetic driving module includes at least one magnetic member, a coil and a circuit board. The frame connects to the casing so as to form an inner compartment therein. The driven object is received and movable along the Z axis inside the inner compartment. One of the magnetic member and the coil is fixed to the driven object while another thereof is fixed to the frame in such a corresponding manner that, when the coil is powered via the circuit board, the driven object would be moved linearly. By means of the anti-tilt mechanism, possible kinetic tilt caused by movements of the driven object upon when the driven object is driven to move along the Z axis can then be eliminated.

The electromagnetic driving module includes at least one magnetic member and at least one coil. The base connects to the casing so as to form an inner compartment thereinside.

With the anti-tilt mechanism to provide lateral pressing forcing to eliminate possible gap between components connecting the driven object and the casing while the driven object is moved along the Z axis inside the inner compartment, possible dynamic tilt of the moving driven object can then be diminished.
