ABSTRACT:
A dust protection device for an image sensor includes a housing in which the image sensor is mounted. The housing includes an aperture for allowing reflected light from the object being viewed to enter the housing and impinge upon the image sensor. A trasparent film is mounted across the aperture for prefenting dust from entering the housing. The transparent film is selectively movable for providing a continuous clean surface across the aperture.
