Abstract
An image projection apparatus () joins a plurality of display images displayed by scanning a plurality of light beams, as if there is no seam between them, thereby displaying a large-sized high-quality image. The image projection apparatus () includes a MEMS mirror device (), a MEMS mirror control unit (), and a laser beam detector (). The MEMS mirror control unit () makes the laser beam detector () irradiated with a first light beam (L), and at this time adjusts a position of a first display image () on the basis of a difference between a detection signal output from a first light sensor () and a detection signal output from a second light sensor (); the MEMS mirror control unit () makes a first light reception surface and a second light reception surface irradiated with a second light beam (L), and at this time adjusts a position of a second display image () on the basis of a difference between a detection signal output from the first light sensor () and a detection signal output from the second light sensor ().
