Problems solved by technology

However, as mentioned above, the problem is that the setting and adjustment of each shot requires a lot of effort and time, so there is still a problem that it is not suitable for shooting interviews with people, or shooting against the background of sports relays

Abstract

A stereoscopic image capturing apparatus includes an objective optical system that has a function of forming a subject as a real image or an imaginary image, a plurality of image forming optical systems that respectively form a plurality of subject light beams emitted from different paths of the objective optical system as parallax images again, using a plurality of independent optical systems, a plurality of imaging devices that convert the parallax images formed by the plurality of image forming optical system into image signals, and a control unit that adjusts a formation position of a convergence point such that a ratio of a focal length of the objective optical system and a distance in an optical axis direction of the objective optical system between a focal point of the objective optical system and a primary principal point of the image forming optical system is substantially constant.

Description

technical field [0001] The present invention relates to a stereoscopic image capturing device for capturing stereoscopic images, and more particularly relates to focus adjustment technology when capturing stereoscopic images. Background technique [0002] In recent years, demand for video cameras (stereoscopic image capturing devices) capable of capturing 3D (stereoscopic) images has been increasing. For methods of capturing stereoscopic images, there are beam splitter type (half mirror type) for capturing images using a half mirror, side-by-side type (parallel twin lens type) for capturing images using two imaging devices physically arranged and mounted, and the like. In these shooting types, the imaging device is mounted on a stand called a rig and shooting is performed, so the degree of freedom in mounting the imaging device increases. For example, the distance between two lenses for capturing a stereoscopic image (hereinafter, referred to as IAD: Inter Axial Distance), ...
