- Distortions in the perceived image characteristics for three different camera arrangements of parallel, converging, and
diverging are different according to each focal length, focus distance, field of view angle, color, magnification, and
camera aligning direction. The distortions in perceived image for the parallel and converging arrangements have been
researched commercially available stereoscopic TV based on high speed LCD, shutter glasses, and mobile devices.
However, the distortion in the perceived image for diverging arrangement is not well known. This paper discusses the
distortion in perceived image characteristics of diverging type stereo camera according to the magnification determining
the enlargement and reduction of a camera image, and they are compared with those of other camera arrangements such
as parallel and converging types. Also, the distortion induces the image closer to the viewers for the diverging type while
away for the converging. The inducement is more prominent as the camera distance between two component cameras of
the stereo camera for the diverging type. Furthermore, the effect of diverging angle on disparity will be considered that
the inter-camera distance can be made as small as possible.
