Abstract
Systems and methods for performing fast zero recovery with alpha blending with digital image stabilization implemented in a digital camera. The digital camera includes a gyroscope to measure motion of the digital camera and processes the signals from the gyroscope to track the total displacement of an image sensor over a series of frames of video. If the motion is a sustained motion in a substantially uniform direction, then the digital camera recognizes the motion as a panning-type motion and activates a fast-zero recovery with alpha blending operation to retrace the displacement of active pixel locations to the center of the image sensor. Alpha blending is performed to smooth the transition from a normal image stabilization operation to the fast-zero recovery with alpha blending operation.
