This paper describes a video projection system with reduced motion blur using a high-speed DMD (Digital Micromirror Device) projector. Conventional DMD devices suffer from motion artifacts, which are observed as blurred moving objects, because of eye motion. A DMD projector displays grayscale brightness by pulse-width modulation and requires many patterns for a frame. In a motion video, image positions are updated per frame, which causes large motion blur. To address this issue, we propose a method in which image positions are updated per pattern. To examine whether the proposed method can give an improved result, an evaluation experiment was conducted. The result of the t-test applied to this evaluation experiment proved that there was significant difference at p<.001 between the proposed method and the conventional one, and the motion blur reduction was successful
