This paper considers the architecture and the effectiveness of new algorithms that control the subjective depth on 3-D displays by modulating the contrast of stereoscopic pictures on the basis of a quantified monocular depth cue. First, a psychophysical experiment to quantify the relationship between contrast and subjective depth was conducted. This experimental result shows that the higher the contrast, the nearer the object will be perceived, corresponding to the qualitative relationship. Second, this result was applied to image-processing algorithms that expand or contract the subjective depth of stereoscopic pictures. Subjective assessments to verify the effectiveness of the algorithms were also conducted. The results suggest that the algorithms will allow viewers to experience a highly realistic sensation.
