1. A method of capturing an image in a digital camera, comprising: receiving a previous image input of a previous image frame and forming a sharpness value of the previous image input; receiving a current image input of a current image frame and forming a sharpness value of the current image input; predicting that a next image frame motion will be less than a current image frame motion, the prediction being based at least on the sharpness value of the previous image input, and the sharpness value of the current image input; deciding to capture a next image frame responsive to the prediction; and capturing the next image frame.
