1. A system operable to correct for distortion in a captured image, the distortion in the captured image having been caused by a rotation of an image capture device while the captured image was being captured by the image capture device, the system comprising:

  • an orientation sensor configured to perform a first measurement concurrently with the image capture device capturing the captured image;

    a rotation module configured to generate, based on the first measurement, a rotation matrix;

    a correction module configured to, based on the rotation matrix, produce a corrected image by correcting the distortion in the captured image caused by the rotation of the image capture device; and

    a restoration module configured to selectively revert the corrected image back to the captured image based on (i) the corrected image and (ii) the rotation matrix.
