Slim compact lens optical image stabilization

A camera, comprising:

• a lens having a lens optical axis and an effective focal length (EFL) in the range of 2.5 mm to 50 mm;
• an image sensor with a larger side and a shorter side, the shorter side having a sensor height HS;
• a plurality of magnets;
• a plurality of coils;
• a plurality of magnetic flux measuring devices (MFMDs);
• a moving frame operational to move the lens in a plane perpendicular to the lens optical axis for optical image stabilization (OIS);
• and
• a static frame fixedly coupled to the image sensor,
• wherein each of the moving frame and the static frame includes a plurality of pools that form ball-bearings between the moving frame and the static frame,
• wherein each ball-bearing includes a ball,
• wherein the ball-bearings allow a free movement of the balls within the borders of the pools,
• wherein a largest dimension of a magnet and a coil is larger than HS/2,
• wherein a first MFMD of the plurality of MFMDs is located at a center of a first coil,
• wherein a second MFMD of the plurality of MFMDs is located at a center of a second coil so that the first and second MFMD are surrounded by the first and second coil respectively,
• and wherein the camera is included in a mobile device.
