Problems solved by technology

[0005] However, there is a problem in that although the degree of freedom is high, it takes a lot of effort and time to set and adjust for each capture to install the stereoscopic imaging device on the stand
In addition, there is a problem that especially the gantry of the imaging equipment using the beam splitter type is a large equipment, and it is not suitable to capture or cover in the field of view
For this reason, for example, in the case of capturing a subject very closely, the parallax displayed on the 3D display at a position just a few meters behind the subject is beyond the parallax range in which a person can comfortably observe a 3D image

[0045] First, refer to Figure 1A and Figure 1B The principle of an effective pupil formed by a stereo camera will be described. Figure 1A and Figure 1B A stereoscopic imaging apparatus 50 shown in includes an objective optical system 10 , an imaging unit 20L, and an imaging unit 20R. The objective optical system 10 has a function of forming a subject (not shown) as a real image. That is, the objective optical system 10 is configured as a focus optical system. Figure 1A An example is shown in which a positive lens (convex lens) 11p having a positive refractive power is used as the objective optical system 10, and Figure 1B An example is shown in which a negative lens (concave lens) 11 m having negative refractive power is used as the objective optical system 10 .

[0046] The imaging unit 20R and the imaging unit 20L include an image forming optical system (not shown), and the image forming optical system forms a plurality of subje...

Abstract

According to an illustrative embodiment, an imaging system is provided. The system includes a first imaging unit; a second imaging unit; and an objective optical system optically coupled to the first imaging unit and the second imaging unit, wherein the objective optical system has a first direction along which light is refracted and a second direction along which light is refracted differently.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application JP2011-273664 filed with the Japan Patent Office on Dec. 14, 2011, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a stereoscopic imaging apparatus for capturing stereoscopic images, and more particularly, to a technique for reducing adverse effects of aberrations occurring in signals exerted on formation of stereoscopic images. Background technique [0004] In recent years, there has been an increasing demand for cameras (stereoscopic imaging devices) capable of capturing 3D (stereoscopic) images. As a method of capturing stereoscopic images, a beam splitter type (half mirror type) that captures images using a half mirror, a side-by-side type that captures images using two cameras that are physically arranged and installed (parallel dual lens type), etc. In these capturing ty...
