Claim 3:
4. The method of claim 1, further comprising:
generating a third motion extracted image based at least in part on a fifth image data generated by the imaging component at a fifth time and a sixth image data generated by the imaging component at a sixth time;
generating a fourth motion extracted image based at least in part on a seventh image data generated by the imaging component at a seventh time and an eighth image data generated by the imaging component at an eighth time;
comparing the third motion extracted image and the fourth motion extracted image to determine a second difference between the third motion extracted image and the fourth motion extracted image;
determining that the second difference does not exceed a threshold; and
in response to determining that the second difference does not exceed the threshold, determining that a second event has not occurred.
