Abstract
We have developed a reliable and practical HD stereoscopic camera system. It consists of a pair of full digital box-type HD video camera, small radius SD class lens, a multiplexer board and some other control boards. The camera is a parallel-axes style. We control the convergence by moving the lens slightly inward which is separated from the camera body. We have used two sets of linear motor modules to control the convergence and the distance between the two cameras precisely. The various camera parameters concerned with stereoscopic view can be displayed in the viewfinder, stored with video and used for studying picture quality improvement and assessment. We have combined zoom control with convergence control for the convenience of stereoscopic image capturing, so we can control them with one knob. They also can be controlled individually. The built-in multiplexer board receives two video signals from the left and right camera, and makes them into one side-by-side image that is compressed in half horizontally and multiplexed two images. After this process we can record the video into a normal VCR, then reconstruct the original two images by demultiplexer, and we can enjoy stereoscopic images.
