Abstract: An image projection image for projecting an image on a screen includes a light source, a scanning mirror and a prism. The light source includes laser diodes for emitting beams of different wavelengths. The scanning mirror reflects the beams radiated from the light source and projects the reflected beams. The prism is disposed at the rear of the scanning mirror to decenter the beams via the scanning mirror based on the wavelengths. In the image projection apparatus, the laser diodes are fixed to be vertically spaced apart from a reference height, corresponding to the wavelengths of the beams.
