In this paper, first, we describe the improved phase-correlation method used to measure the amount of horizontal shift between the left and right images of stereoscopic HDTV programs. Second, we measured the amount of horizontal shift of 48 stereoscopic HDTV images using the method. Third, we carried out a subjective evaluation test to assess how comfortable (or uncomfortable) each of these images was to view. The results indicated that the comfortable viewing range of parallax distribution in a frame was within approximately 0.3 diopters.
