A light projection device (100a) is mounted on a mobile unit for varying the position of the light projection device or the direction in which light is projected, the light projection device including: a light projection unit (3) which has a light projection optical system (31) for projecting light and which projects a light beam in a predetermined shape to a light-projected object (Ob); a shake detection unit (2a) for detecting the amount of shake of the light projection device (100a); and a light projection direction varying unit (4) for varying the direction of light projection of the light projection unit (3) depending on the amount of shake detected by the shake detection unit (2a) so as to project light to the light-projected object (Ob). |
