<P>PROBLEM TO BE SOLVED: To provide a stereoscopic imaging optical system having an adjustment function of a stereo base, an imaging device including the stereoscopic imaging optical system, and a camera having the imaging device. <P>SOLUTION: In the stereoscopic imaging optical system which includes two imaging lens systems arranged in parallel, two diaphragms arranged in each of the imaging lens systems, and diaphragm position driving means for driving the position of the diaphragm, at least one of the diaphragms adjusts a stereo base by eccentricity with respect to an optical axis, and satisfies conditions (1.8≤SBmax/(fT×tan(ωT))≤45) (SBmax: maximum value of stereo base, fT: focal distance of optical system at telephoto end, and ωT: half field angle at telephoto end (°)). <P>COPYRIGHT: (C)2012,JPO&INPIT |
