1. A method for capturing an image, the method comprising:
- receiving light through an imaging lens having an adjustable focal center;
estimating a motion vector representing motion of the imaging lens;
estimating a shift vector in response to the motion vector;
converting the shift vector into a voltage gradient; and
providing the voltage gradient to the imaging lens,wherein the focal center of the imaging lens is shifted based on the voltage gradient to compensate for the motion of the imaging lens.

Abstract
Methods and systems for capturing an image. Light is received through an imaging lens that has an adjustable focal center. A motion vector representing motion of the imaging lens is estimated and a shift vector is estimated in response to the motion vector. The shift vector is converted into a voltage gradient and provided to the imaging lens. The voltage gradient shifts the focal center of the imaging lens to compensate for the motion of the imaging lens.
