ABSTRACT:
An attitude sensor for determining camera orientation comprises gravity responsive means supported for movement to various positions in accordance with changes in camera orientation and fixed means for determining the gravity responsive means has moved to anyone of its positions. The gravity responsive means includes a plurality of discrete sections which have different degrees of light reflectivity or light transmissivity and are arranged to alternately occupy a predetermined location when the gravity responsive means is moved to respective ones of its positions. The fixed means includes photo-emitting means for directing light to whichever one of the discrete sections of the gravity responsive is occupying the predetermined location and photo-responsive means for providing a measure of light reflected from or transmitted by that one section.
