1. A method of correcting a rotation of a video frame, the method comprising:
- detecting an amount of the rotation of a video frame with respect to a reference; and
correcting the rotation of the video frame based at least in part on the detected amount of the rotation of the video frame, wherein the determined amount to correct the rotation of the video frame is any number of degrees of rotation between the reference and the obtained video frame.
