<p>PROBLEM TO BE SOLVED: To provide a see-through glass type display device which makes it possible to perceive a virtual image in spatial coherence with an ambient scene image.SOLUTION: A display device 100 comprises: an optical unit 110 having a front correcting surface and a rear correcting surface 116a; an image projector 130 projecting a virtual image; and an image sensor 120 for capturing an ambient scene image. The optical unit 110 is configured to guide light of the ambient scene image coming through the front correcting surface 112a to the image sensor 120 and to guide light of the virtual image so that the light of the virtual image outgoes through the rear correcting surface 116a. A first optical compensation element 124 is located between the optical unit 110 and the image sensor 120, and a second optical compensation element 134 is located between the image projector 130 and the optical unit 110. The device further comprises a processing module 140 configured to analyze the ambient scene image captured by the image sensor 120.</p> |
