(54) Title: MEMS SCANNING DISPLAY DEVICE (57) : Examples are disclosed that related to scanning image display systems. In one example, a scanning head-mounted display system includes a light source, a motion sensor, a scanning mirror system configured to scan light from the light source along at least one dimension to form an image, and a controller configured to control the scanning mirror system to scan the light to form the image, receive head motion data from the motion sensor, and adjust one or more of a scan rate and a phase offset between a first frame and a second frame of the image based upon the head motion data.
