Abstract
An apparatus includes an image capture sensor, a gyroscope, an accelerometer, a feedback module, a rotation module, a correction module, and a restoration module. The image capture sensor captures an image. The gyroscope makes a first measurement that indicates an orientation of the image capture sensor relative to a reference orientation. The accelerometer makes a second measurement. The feedback module generates a corrected first measurement to correct for drift of the gyroscope in response to the second measurement. The rotation module generates a rotation matrix based on the corrected first measurement. The correction module corrects the image captured by the image capture sensor based on the rotation matrix. The restoration module selectively restores the image captured by the image capture sensor based on (i) the image as corrected by the correction module and (ii) the rotation matrix.
