Abstract In the conventional temporally interlaced S3D protocol, red, green, and blue are presented simultaneously to one eye and then to the other eye. Thus, images are presented in alternating fashion to the two eyes. Moving objects presented with this protocol are often perceived at incorrect depth relative to stationary parts of the scene. We implemented a colorinterlaced protocol that could in principle minimize or even eliminate such depth distortions. In this protocol, green is presented to one eye and red and blue to the other eye at the same time. Then red and blue are presented to the first eye and green to the second. Using a stereoscope, we emulated the color-interlaced protocol and measured the magnitude of depth distortions as a function of object speed. The results showed that color interlacing yields smaller depth distortions than temporal interlacing in most cases and never yields larger distortions. Indeed, when color interlacing produces no brightness change within sub-frames, the distortions are eliminated altogether. The results also show that the visual system’s calculation of depth from disparity is based on luminance, not chromatic signals. In conclusion, color interlacing provides great potential for improved stereo presentation.
