Claim 5:
6. An image output device, comprising:
a light source unit including a plurality of light sources and outputting a plurality of light beams having a difference between the light paths which is equal to or less than the width of the pupil of the user' eye;
a display element receiving the light beams from the light source unit and reflecting augmented reality images;
a reflector reflecting the light beams output from the light source unit and transmitting the augmented reality images reflected by the display element; and
a controller controlling the light source unit to sequentially or simultaneously output the light beams and the display element to output the augmented reality images corresponding to the output light paths, wherein the output images have multiple focuses, and
wherein the light beams output from the point light sources pass through the reflector and the display device to be output as the augmented reality images with different light paths, and the augmented reality images corresponding to the output light vary according to the output light paths,
wherein the depth of the plane of the image reproduced is determined depending on the interval between the point light sources, and
wherein the path differences between the augmented reality images obtained by the light output from the point light sources amount to about 2 to 6 mm.
