<P>PROBLEM TO BE SOLVED: To obtain a camera system capable of reducing the fluctuation of the position of the entrance pupil of a zoom lens caused by zooming, reducing the change of base length between a plurality of zoom lenses and obtaining a parallactic image suitable for stereoscopic vision while contriving the miniaturization of the zoom lens. <P>SOLUTION: The camera system has at least a pair of photographing systems provided with: the zoom lens comprising such lens constitution that the position of the entrance pupil is fluctuated by zooming, and supported to turn with a direction including an intersection of the position of the entrance pupil with an optical axis at a certain zoom position and orthogonal to the optical axis as an axis of rotation; and an imaging means on the image side of the zoom lens, wherein the pair of zoom lenses is arranged at the interval of fixed base length, and the respective parallactic images are picked up by the pair of photographing systems. The camera system has a control means controlling to spatially fix the position of the entrance pupil fluctuated with the zooming of the zoom lens by integrally moving the zoom lens and the imaging means in an optical axis direction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
