For distortionless stereoscopic display, it is necessary to reconstruct the visual space congruent with the taken space by stereoscopic camera. In field-sequential stereoscopic display, it is difficult to keep the fixed geometric relation between screen and eyes, because the images are displayed on the fixed screen. Some spatial distortions are also caused by the projection of both the left and the right images on the same screen. In this paper, a displaying method of field-sequential stereo images using virtual screens united with observer's eyes are described. By measuring the relative positions of observers eyes and display screen and doing the perspective projection of virtual screen images using 3D computer graphics functions, the congruent space with the taken space by stereoscopic camera can be always reconstructed.
