Abstract
A projection apparatus capable of appropriately performing shift control of a projection image when a posture or a projection direction of a projection lens is changed by rotating the projection lens is provided. A projection apparatus () includes a projection apparatus main body () that causes a DMD (B) to emit a projection image; a projection lens () that projects the projection image emitted from the DMD (B), the projection lens () including a second optical system and a third optical system, the second optical system being provided rotatably around a first rotation axis with respect to the projection apparatus main body (), the third optical system being rotatable around a second rotation axis extending in a direction intersecting with the first rotation axis; a posture information acquisition unit that acquires posture information indicating a posture of the projection lens () with respect to the projection apparatus main body (); a lens shift mechanism () that causes the projection lens () to move in a plane intersecting with an axial direction of the first rotation axis; and a control unit that controls the lens shift mechanism () based on the posture information acquired by the posture information acquisition unit to shift a projection image that is projected from the projection lens ().
