<p>In a stereoscopic image capture device having a single imaging optical system, initial F value FNo1 of a diaphragm and focal length f1 of an imaging lens are acquired (steps S10 and S12). Afterwards, when the focal length of the imaging lens changes to f2, the F value (FNo2) that does not change the stereoscopic effect of right and left parallax images for stereoscopic parallax acquired from the stereoscopic image capture device before and after adjusting the focal length is calculated by a predetermined conditional equation (FNo2=FNo1*(f2/f1) 2 ) (step S18), and the diaphragm is controlled so as to become this calculated F value (FNo2) (step S20). By this means, in a case where the angle of view is adjusted by changing the focal length of the imaging lens, it is possible to cause the stereoscopic effect not to be changed.</p> |
