Abstract
Official abstract text for this publication.
The present invention relates to an apparatus equipped with a depth of field control function for enabling augmented reality, which is capable of controlling the depth of field and focus and also preventing an image from being blurred due to diffraction by using a pseudo-pinhole effect. The apparatus includes: a display unit configured to generate a virtual image; a circular depth of field control unit configured to have a size in a range from 50 to 700 μm, and also configured to reflect the virtual image generated in the display unit, to increase the depth of field of the virtual image, and to then enable the virtual image to reach an eye of the user; and a frame part configured such that the display unit and the depth of field control unit are installed thereon or therein, and also configured to enable the user to wear the apparatus for enabling augmented reality.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus equipped with a depth of field control function for enabling augmented reality, the apparatus being configured to be worn on a user, the apparatus comprising: a display unit ( 10 ) configured to generate a virtual image; a depth of field control unit ( 20 ) configured to have a size smaller than an eye pupil of a human, and also configured to reflect the virtual image generated in the display unit ( 10 ), to increase a depth of field of the virtual image, and to then enable the virtual image to reach an eye of the user; a frame part ( 30 ) configured such that the display unit ( 10 ) and the depth of field control unit ( 20 ) are installed thereon or therein, and also configured to enable the user to wear the apparatus for enabling augmented reality; and a plurality of display units ( 10 and 10 ′) and a plurality of depth of field control units ( 20 and 20 ′) for a single eye of the user.
