STEREOSCOPIC PHOTOGRAPHY

摘要

A camera, capable of generating a stereoscopic effect using a single optical path between the subject and the photosensitive medium, employs a coding member (75, 76), or assembly of elements such as an iris (82) having different coding effects to either side of a diametral centre line with the coding effects appropriate to decoding means such as spectacles in front of the eyes of an observer. The coding effect may be by way of filter material of different colorations to either side of the centre line or coding elements which are separately switchable between a transparent state and a less transparent or opaque state in synchronism between the switching of a coding element (23) and a decoding element (27) of viewing means such as spectacles.
