Optical convergence angle adjustment three-dimensional image pickup device and optical convergence angle adjustment three-dimensional image pickup method

摘要

PROBLEM TO BE SOLVED: To enable a user to view a subject expanded or reduced in a state of being localized in a screen surface even when picking up an image while zooming.SOLUTION: An optical convergence angle adjustment 3D image pickup device includes a first video camera 102R, a second video camera 102L, and a convergence angle adjustment part. The first and second video cameras include optical imaging lenses Land are so set that optical axes of these lenses are orthogonal to imaging surfaces (Sand S). Each of these imaging lenses is formed by combining a tilt-shift lens and a zoom lens. In order to keep a convergence angle ω constant so as to always localize a subject indicated by Q on the screen surface regardless of zooming operation, the device is configured so that the convergence angle adjustment part executes control for shifting the tilt-shift lenses by aand aso as to satisfy a/f=a/f(=tanω) where fand fare focal lengths of the imaging lenses.
