Patent ID: 8711235

Claim:
A system to stabilize images of digital cameras by mechanically adjusting a part of the optical system of the camera to unintentional movements of the camera during capture of an image is comprising: a gyroscopic sensor, sensing an angle speed of the camera, wherein an output of the gyroscopic sensor is an input to an electronic regulator; said electronic regulator controlling a position of said part of the optical system, to be adjusted, wherein said part is moved by at least two linear motors dependent upon the input from said gyroscopic sensor, and, wherein position sensors are providing information about an actual position to the electronic regulator; wherein each of said first parts of each of said linear motors comprises magnetic material and each of said second parts comprises one or more coils wrapped around magnetic material; wherein a second coil wrapped around said magnetic material is used for position sensing by measuring a difference of inductance between both coils; an x-y table carrying said part of the optical system to be adjusted, comprising a movable first plate and a fixed second plate, wherein first parts of the linear motors are mounted to the first plate and second parts are mounted to the fixed second plate; and said position sensors providing input to said electronic regulator.
