Systems and methods for an optical image stabilizer system

A computer-implemented method of operating an optical image stabilizer for a lens of a camera module coupled to a gyro sensor system and disposed within a portable device, comprising:

• detecting from a position detection sensor linked to the lens:
• an initial position of the lens according to a force of gravity on the lens and a force applied by a set of springs connected to the lens;
• and
• a new position of the lens resulting from a movement of the lens;
• receiving from an accelerometer coupled to the lens a set of acceleration data corresponding to an acceleration rate of the lens in at least two dimensions;
• determining a target position for the lens based on the acceleration data, comprising:
• orienting the lens in a first orientation, wherein:
• a first axis comprises a vertical axis upon which the force of gravity applies;
• performing a set of measurements in the first orientation;
• orienting the lens in a second orientation, wherein:
• a second axis comprises the vertical axis upon which the force of gravity applies;
• and
• performing a set of measurements in the second orientation;
• and
• actuating the lens towards the target position.
