PROBLEM TO BE SOLVED: To provide a projector that can easily adjust the direction of an image to be displayed even when a projection target surface is freely selected by a user, and a method for controlling display of the projector.SOLUTION: A projector comprises a reflecting mirror 35 that reflects and displays light projected from a projection optical system 43. The reflecting mirror 35 is provided displaceable between a position extending on a light path in a light emission direction of the projection optical system 43 and reflecting an image and a position outside the light path, and includes an opening detection part 21 that detects the opening of the reflecting mirror 35, and a direction adjustment part 23 that adjusts the direction of an image formed by a light modulation device 42 according to the detected opening of the reflecting mirror 35.SELECTED DRAWING: Figure 2 【課題】被投射面を自由に選択した場合であっても、表示される画像の向きを容易に調整することができるプロジェクター、及び、プロジェクターの表示制御方法を提供する。【解決手段】投射光学系４３から投射された光を反射して表示する反射鏡３５を備え、反射鏡３５は、投射光学系４３の出射方向の光路上に延在して画像を反射する位置と光路から外れた位置との間を変位可能に設けられ、反射鏡３５の開度を検出する開度検出部２１と、検出された反射鏡３５の開度に応じて、光変調装置４２が形成する画像の向きを調整する向き調整部２３を備える。【選択図】図２
