Abstract
An image projection apparatus according to the present invention includes a light source for outputting laser light and a mirror section for reflecting and projecting the laser light having been output from the light source, and displays an image with at least a portion of the projected laser light. The image projection apparatus includes a detection section for detecting at least a portion of the laser light returning from a projection direction of the laser light, and a calculation section for determining an image displayable region based on the detected light. The mirror section reflects at least a portion of the laser light returning from the projection direction of the laser light so as to be led into the detection section.
