ABSTRACT:
The stereoscopic convergence is adjusted in stereoscopic imaging equipment to increase or decrease the stereoscopic convergence angle. Two imaging devices are disposed symmetrically relative to a median optical axis to generate video signals representing images of an observed scene. Depending on the required stereoscopic convergence angle, two image "read windows" are positioned symmetrically relative to the median optical axis, each being defined by a first pixel and a last pixel of a processed image line. The first and last pixels of a processed line are disposed between the first and last pixels of a raw (oversize) image line, with the result that the video signals generated by the stereoscopic imaging equipment represent righthand and lefthand processed images in corresponding relationship to the raw image read windows.
