Abstract: A projector includes a light source configured to provide light, a digital micromirror device configured to form a video by selectively reflecting the light, a projection lens configured to enlarge and project the light reflected by the digital micromirror device onto a screen, and the actuator assembly disposed between the digital micromirror device and the projection lens and configured to allow the light incident on the projection lens from the digital micromirror device to travel straight or be refracted. The actuator assembly includes a first actuator including a first glass, and a second actuator including a second glass.

Abstract: An image projection apparatus according to an embodiment of the present invention senses the distance to an image projection area to which an image is projected, and determines an image projection state including a state of at least one of the image projection area and a space between the image projection apparatus and the image projection area, on the basis of the sensed distance. The image projection apparatus projects an image onto the image projection area on the basis of the determined image projection state.
