Abstract
A stereoscopic television system employs a plurality of camera units each having an optical system and an image pickup element to photograph and display images of an object. The displayed images are processed with a stereoscopic image processor to provide stereoscopic images. The system comprises detectors for receiving image signals based on the images photogaphed by the camera units and correlatively comparing the image signals with each other to detect deviations of the images photographed by the camera units and provide image deviation signals; and correcting devices for correcting the deviations of the images according to the image deviation signals provided by the detectors.
