A projection apparatus capable of, when an image input from an external device and an OSD image are rotated by rotation of a projection lens, performing rotation correction suitable for the respective images is provided. A projection apparatus () includes a housing; a projection lens () that has a holder and that is rotatably attached to the housing; a first rotation position detection unit (A) and a second rotation position detection unit (B) that detect rotation states of the holder; a DMD (B) that outputs, to the projection lens (), a composite image of a projection image output from an external device and an OSD image including a character output from an internal memory; and a control unit that performs rotation correction on the OSD image and that does not perform rotation correction on the projection image based on detection results of the first rotation position detection unit (A) and the second rotation position detection unit (B) when the holder of the projection lens () rotates.
