Temporal interlacing is a method for presenting stereoscopic 3D content whereby the two eyes’ views are presented at different times and optical filtering selectively delivers the appropriate view to each eye. This approach is prone to distortions in perceived depth because the visual system can interpret the temporal delay between binocular views as spatial disparity. We propose a novel color-interlacing display protocol that reverses the order of binocular presentation for the green primary but maintains the order for the red and blue primaries: During the first sub-frame, the left eye sees the green component of the left-eye view and the right eye sees the red and blue components of the right-eye view, and vice versa during the second sub-frame. The proposed method distributes the luminance of each eye’s view more evenly over time. Because disparity estimation is based primarily on luminance information, a more even distribution of luminance over time should reduce depth distortion. We conducted a psychophysical experiment to test these expectations and indeed found that less depth distortion occurs with color interlacing than temporal interlacing.
