Abstract

An optical see-through glass type display device comprises: an optical unit having a front correcting surface and a rear correcting surface; an image projector projecting a virtual image; and an image sensor for capturing an ambient scene image. The optical unit is configured to guide light of the ambient scene image coming through the front correcting surface to the image sensor and to guide light of the virtual image so that the light of the virtual image outgoes through the rear correcting surface. A first optical compensation element is located between the optical unit and the image sensor and a second optical compensation element is located between the image projector and the optical unit. The device further comprises a processing module configured to analyze the ambient scene image captured by the image sensor.
