Summary:PROBLEM TO BE SOLVED: To provide an image projection apparatus capable of achieving extension of a production life and suppressing power consumption while achieving high resolution corresponding to a moving image.SOLUTION: An image projection apparatus 1 comprises: a movable unit 55 having a DMD 551 configured to generate a projection image corresponding to a moving image, by using light of a light source 30, and movable relative to an illuminating optical system unit; a video signal control section 11 configured to generate a control instruction for display control of a projection image, on the basis of a moving image to be projected; and a movable unit control section 25 configured to control movement of the movable unit 55 on the basis of a control instruction. In a case where a moving image satisfies a predetermined condition, the video signal control section 11 generates, as a control instruction, a first control instruction not to move the movable unit 55. In a case where the moving image does not satisfy the predetermined condition, it generates, as a control instruction, a second control instruction to move the movable unit 55.SELECTED DRAWING: Figure 2 【課題】動画像に応じた高解像度を実現しつつ、製品寿命を伸ばすとともに電力消費量を抑えることができる画像投射装置を提供すること。【解決手段】画像投射装置１は、動画像に対応する投影画像を光源３０の光を用いて生成するＤＭＤ５５１を有するとともに、照明光学系ユニットに対して相対的に移動可能な可動ユニット５５と、投影対象の動画像に基づいて、投影画像の表示制御に関する制御指示を生成する映像信号制御部１１と、制御指示に基づいて、可動ユニット５５の移動を制御する可動ユニット制御部２５と、を備え、映像信号制御部１１は、動画像が所定条件を満たす場合には、制御指示として可動ユニット５５を移動させない第１の制御指示を生成し、動画像が所定条件を満たさない場合には、制御指示として可動ユニット５５を移動させる第２の制御指示を生成する。【選択図】図２
