Perception of Motion-Adaptive Color Images Displayed by a High-Speed DMD Projector

Recent progress of high-speed projectors using DMD (Digital Micromirror Device) has enabled low-latency motion adaptability of displayed images, which is a key challenge in achieving projection-based dynamic interaction systems. This paper presents evaluation of different approaches in achieving fast motion adaptability with DMD projectors through a subjective image evaluation experiment and a discrimination experiment. The results suggest that the approach proposed by the authors, which updates the image position for every binary frame instead of for every video frame, applied to 60-fps video input offers perceptual image quality comparable with the quality offered by 500-fps projection.
