Title: IMAGING DEVICE, HEAD-MOUNTED DISPLAY, AND METHOD FOR GENERATING AN IMAGE FROM AN ORIGINAL IMAGE IN A HEAD-MOUNTED DISPLAY
Abstract:
The invention relates to an imaging device for a head-mounted display for generating a virtual image from an original image split into at least two original subimages. The imaging device comprises: an imager element arrangement (1) comprising a number of imager elements (11 to 16) on which a corresponding number of original subimages is displayed; a number of imaging channels corresponding to the number of imager elements (11 to 16), which each have at least one image-forming reflection surface (271 to 276) and/or at least one image-forming refraction surface (251 to 256, 291 to 296), each of the imaging channels being associated with one of the imager elements (11 to 16) and transmitting one of the original subimages; and an ophthalmic lens (5) common to all of the imaging channels, used to deflect the imaging channels towards an observer's eye. The image-forming reflection surfaces (271 to 276) and/or refraction surfaces (251 to 256, 291 to 296) of the imaging channels are surfaces of a prism (3) arranged on the ophthalmic lens (5).
