<p>A method and device for automatically controlling a polarizing filter (12), featuring automatically sensing, measuring, and analyzing at least one parameter associated with direction of a polarizing filter (12) by an electronic direction/motion sensing mechanism (16), receiving a signal from the electronic direction/motion sensing mechanism (16) relating to the at least one parameter associated with direction of the polarizing filter (12) by rotation control circuit (24), and receiving a signal from the rotation control circuit relating to the at least one parameter associated with direction of the polarizing filter by a polarizing filter rotating mechanism (26) for automatically rotating the polarizing filter. The invention is primarily directed to applications of a polarizing filter (12) in the field of photography, however, it clearly can be directed to applications of a polarizing filter in a variety of other fields involving the use of electromagnetic radiation for viewing, imaging and/or projecting through short or long distances, for example, involving the use of a microscope, binoculars, a telescope, or a laser beam device.</p> |
