Low-latency projection is a key technology for fast motion-adaptive projection. Digital Micromirror Devices (DMDs) are widely used for this purpose because they enable high frame rate projection of binary patterns, although additional techniques are needed to realize projection of multi-valued images. This paper proposes a low-latency projection method, Binary Frame Warping, with which displayed patterns are warped at the binary pattern rate instead of the video frame rate. Experimental results suggest that the proposed method applied to 60-fps video input offers perceived image quality comparable with that offered by over 500-fps projection.
