METHODS AND APPARATUS FOR IMPLEMENTING AND/OR USING CAMERA DEVICES WITH ONE OR MORE LIGHT REDIRECTION DEVICES

摘要

Methods and apparatus relating to a camera including one or more optical chains with a light redirection device, e.g., mirror, and an outer protective cover are described. The cover maybe a flat or sloped surface or a lens. Features avoid stray light rays from reaching an image sensor of an optical chain. In some but not all embodiments a 2-sided anti-reflection coating is used on the cover to avoid or reduce back reflections from the cover into the optical system. In some embodiments mirror angles are limited to a range in which stray light reflections are directed away from the camera module. In some embodiments a tilted cover configuration is used where the cover is sloped relative to a face of the camera and/or camera module. Different features such as the sloped cover glass, control of mirror angle, and/or antireflective coating can be used alone or in combination.
