Abstract:
A motion sensor is used to sense the movement of the camera during an exposure period. The camera has an image sensor to form one or more exposures. When the movement is within a certain range, the exposures are used to provide one or more frames so that an image can be constructed based on the frames. In one embodiment, the exposure period is divided into several short intervals in order to capture several image frames and only the image frames captured when the position of the camera is within a predetermined range are used to form the final image. The exposure time for each frame is small in order to reduce the motion blur degradation of the individual frames. If the camera is stable and substantially stationary relative to the scene, then all or many of the shorter frames are used to form the final image.
