Patent ID: 7967437

Claim:
A retinal scanning image display apparatus comprising: a light source that emits a light flux modulated in accordance with a video signal; a scanning unit that scans a light flux from the light source; a reflective surface that reflects the light flux from the scanning unit; an ocular unit that guides the light flux from the reflective surface to an eye of an observer to project an image generated from the video signal on a retina thereof; and a control unit that controls the scanning unit to scan the light flux two-dimensionally; wherein optical paths of the light flux scanned by the scanning unit intersect at an exit pupil position of the ocular unit, which is where a pupil of the eye is positioned, wherein each of the scanning unit as a whole and the reflective surface is shiftable, and wherein the control unit controls shifting of both the scanning unit as a whole and the reflective surface in accordance with motion of the eye so that the optical paths of the scanned light flux toward the exit pupil position are respectively moved in parallel to move the intersecting position of the optical paths at the exit pupil position to maintain a position of the projected image on the retina.
