Patent ID: 7318646

Claim:
A system for projecting a virtual image within an observer's field of view, comprising: a support element, at least one transparent element which is mounted on the support element and which in a use condition is placed in front of at least one of the observer's eyes in order to transmit an image thereto, the transparent element comprising a first face and a second face which in said use condition face towards and away from the eye, respectively, in such a way to transmit to the eye an image of a portion of outside world extending beyond the transparent element, light emitting means suitable for generating a light signal, and projection and focusing means for projecting the light signal onto the eye in a manner such as to present the light signal as an additional image superimposed on the image of the portion of outside world, focused at a predetermined distance from the eye, wherein: the light emitting means comprise a plurality of light-emitting pixel devices disposed on one of the first and second faces of the transparent element, and the projection and focusing means comprise a plurality of optical elements associated with respective emitting devices and arranged on the other of the first and second faces of the transparent element in a manner such that each of the optical elements can create a virtual image of the emitting device associated therewith, the virtual images of the individual emitting devices together forming the additional image superimposed on the image of the portion of outside world.
