Abstract:
An image projection apparatus includes an image generation element to generate an image using light emitted from a light source, a shift unit to shift a position of the image generation element with a given cycle, a projection control unit to control projection of the image under a plurality of modes, the modes including a first mode in which the image is projected without shifting the position of the image generation element by the shift unit, and a second mode in which the image is projected while shifting the position of the image generation element by the shift unit, and a detector to detect whether the image generation element operates normally. When the detector detects that the image generation element does not operate normally under the second mode, the projection control unit stops image processing being performed, and switches the second mode to the first mode.
