Abstract:
In some embodiments, a method for compensating for lens motion includes estimating a starting position of a lens assembly associated with captured pixel data. The captured pixel data is captured from an image sensor. In some embodiments, the method further includes calculating from the starting position and position data received from the one or more position sensors lens movement associated with the captured pixel data. The lens movement is mapped into pixel movement associated with the captured pixel data. A transform matrix is adjusted to reflect at least the pixel movement. A limit factor associated with the position data is calculated. The captured pixel data is recalculated using the transform matrix and the limit factor.
