Abstract
An image projection device includes a projection unit converging image light beams emitted in different directions from a scanning unit at a first convergence point in user's eye, a reflection unit converging the image light beams at a second convergence point before the projection unit, an optical member being provided between the projection unit and the reflection unit, converting the image light beams into convergent light beams, and causing the image light beams to enter the projection unit as diffusion light beams a drive unit moving the reflection unit, a detection unit detecting a direction in which user's pupil has moved, and a drive control unit controlling the drive unit to move the reflection unit so that incident positions of the image light beams on the optical member change according to the direction in which the pupil has moved.
