  • Publication number: 20190086668
    Abstract: 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 ?m, 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.
