US Patent 7271830 Motion detection in an image capturing device

An image capturing device includes an electronic image sensor, a memory, and a processor. The memory includes a motion detect routine, a predetermined image interval, and at least one predetermined motion threshold. The processor conducts the capturing of images separated by the predetermined image interval, compares a current image to one or more previous images, determines when motion between the current image and the previous image is below the at least one predetermined motion threshold, and stores the current image as a final image when the current image is stable.
