ChromoStereoscopic rendering for trichromatic displays

Abstract

The chromostereopsis phenomenom leads to a differing depth perception of different color hues, e.g., red is perceived slightly in front of blue. In chromostereoscopic rendering 2D images are produced that encode depth in color. While the natural chromostereopsis of our human visual system is rather low, it can be enhanced via ChromaDepth®glasses, which induce chromatic aberrations in one eye by refracting light of different wavelengths differently, hereby offsetting the projected position slightly in one eye. Although, it might seem natural to map depth linearly to hue, which was also the basis of previous solutions, we demonstrate that such a mapping reduces the stereoscopic effect when using standard trichromatic displays or printing systems. We propose an algorithm, which enables an improved stereoscopic experience with reduced artifacts.
