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.

Abstract: An apparatus for projecting an image, according to one embodiment of the present invention, projects an image, detects a user gesture operation in an area between an image screen area, where an image screen corresponding to the projected image is displayed, and the apparatus for projecting an image, and carries out a control operation corresponding to the detected gesture operation. The operation of detecting the user gesture operation includes distinguishing, into a plurality of areas, the area between the image screen area and the apparatus for projecting an image, and detecting the user gesture operation with respect to the plurality of distinguished plurality of areas.
