ABSTRACT:
A stereo camera has an automatic collimation correcting function and excellent operability of observing right and left pictures by one finder. Right and left photographing lenses 4R and 4L are linearly obliquely moved by an inter-optical axis distance/focus adjusting mechanism, and corrected to an inter-optical distance adapted to a focal distance. A composite prism 5 for synthesizing one picture by inverting the outer one-half portions of the photographing fields of the right and left photographing lenses is interlocked to the focal adjustment by a prism moving cam 16 to be moved back and forth, and the focal distance point on the central extension line of the stereo camera is disposed at the center between the right and left finder pictures irrespective of the inter-optical axes distance. The lateral width of the subject image is changed in response to a focal adjustment, and an accurate focus can be adjusted by varying the shape of the image.
