Claim Text:
1. A video stabilization method, comprising: obtaining motion data from a motion sensor different from an imaging sensor corresponding to motion of a camera; estimating from the motion data and previous motion data from the motion sensor, instantaneous motion of a camera for a current frame of a video sequence; comparing the instantaneous motion to a threshold value representing a relatively still condition; reducing a video stabilization strength parameter for the current frame if the instantaneous motion is less than the threshold value, the video stabilization strength parameter defining an overall degree of video stabilization to be performed for the current frame, wherein the video stabilization strength parameter is decreased by a first value if the instantaneous motion of the current frame is below the threshold value and the instantaneous motion of a preceding frame is equal to or above the threshold value, the video stabilization strength parameter is decreased by a second value if the instantaneous motion of the current frame and the previous frame are below the threshold value, and wherein the first value is smaller than the second value; and performing video stabilization on the current frame according to the frame's video stabilization strength parameter.
