1. A method of compensating for error measurement in depth images due to relative motion between a system acquiring the images using an array of pixels and a target object being imaged, the method comprising the following steps:

  • (a) acquiring a sequence of images;

    (b) normalizing the acquired said sequence of images relative to a referenced one of said images;

    (c) detecting presence of at least one of coarse motion associated with movement of said system, and local motion associated with movement of said target object, in said acquired said sequence of images; and

    (d) compensating for at least one of coarse motion and local motion in said acquired said sequence of said images;

    wherein images so compensated at step (d) are substantially free of distance error due to said relative motion.
