We describe the development and evaluation of an electro- optical 3D adapter for recording stereoscopic 3D images with a standard video camcorder. The adapter uses a combination of liquid crystal shutters and a half prism to record right and left images in each field of an NTSC signal. The purpose of this study was to develop a simple and usable 3D recording system. We investigated the usability of a conventional -model 3D adapter and examined solutions to the problems we found. This adapter has the following characteristics: 1) The 3D recordings were made using the parallel method. 2) The frame of the adapter does not obstruct light in any part of the images. 3) A correcting lens is used in close-up recordings to equalize the sizes of the right and left images. 4) The vertical disparity of each image is easy to adjust. 5) The base length can be adjusted to between 65mm and 90mm.
