In general, most conventional three-dimensional moving image capturing device uses two cameras for capturing the right and left video signals of an object. But this system has many disadvantages in that it essentially requires two cameras each having various accessories, and in that it is difficult and takes much time to integrate the moving images. Also, some calibration and rectification processes must be needed in the practical applications, because the operational characteristics of these two cameras can't be made to be same. On the other hand various camcorder adapters for capturing 3D moving image have been developed in order to eliminate the disadvantages of this two-camera system. But in this system, an entrance pupil point is formed inside the 3D moving image capturing device, so that when a wide moving image having a wider picture angle is to be captured, it is necessary to greatly increase the sizes of the total reflecting mirrors, which causes the adapter housing having the total reflecting mirrors mounted therein to be increased in size. Accordingly, in this paper, a new compact electro-optical 3D camcorder adapter for effectively capturing three-dimensional image having any picture angles is proposed and its performance is analyzed by comparing with those of the conventional ones. Some experimental results also confirm the superiority of the proposed system and its usefulness in the practical applications.
