1. An apparatus comprising:

  • an image capture sensor configured to capture an image;

    a gyroscope configured to make a first measurement, wherein the first measurement indicates an orientation of the image capture sensor relative to a reference orientation;

    an accelerometer configured to make a second measurement;

    a feedback module configured to, in response to the second measurement, generate a corrected first measurement to correct for drift of the gyroscope;

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

    a correction module configured to, based on the rotation matrix, correct the image captured by the image capture sensor; and

    a restoration module configured to selectively restore the image captured by the image capture sensor based on (i) the image as corrected by the correction module and (ii) the rotation matrix.
