Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce image quality degradation when a plurality of compact projectors with MEMS and semiconductor laser light sources are stacked.SOLUTION: An image display device includes image projection means comprising: a plurality of light sources; light source driving means for driving the light sources; a reflection mirror that reflects light emitted from the light sources and projects it to an object; mirror driving means for driving the reflection mirror; and image processing means for processing an input video signal and correcting special distortion of an image. The image projection means projection-displays images by scanning the emission light with the reflection mirror. The image display device uses a plurality of image projection means to project the images in the same region in a superimposed manner to form one composite image. The image display device includes a sensor for measuring a projection surface for projection display. The sensor transmits a correction coefficient to the image processing means to correct image distortion of the composite image or composite misalignment.
