Abstract
A stereoscopic imaging method using: first and second imaging devices including first and second imaging optical systems with first and second focus lenses and imaging a subject to generate first and second images; and a lens driving device configured to move the first and second focus lenses along the first and second optical axes of the first and second imaging optical systems, respectively, the method includes: moving the focus lenses to detect first and second focus positions in an imaging space of the first and second focus lenses, respectively; calculating a stereoscopic view possible range where a parallax amount of the first and second imaging device is within an acceptable range; determining whether the focus positions are between an intersection of the optical axes and a near point of the stereoscopic view possible range; and causing the lens driving device to focus the first and second focus lens on the determined focus position.
