    摘要： A head-mounted display system is configured to project light to an eye of a user wearing the head-mounted display system to display content in a vision field of said user. The head-mounted display system comprises at least one diffusive optical element, at least one out-coupling optical element, at least one mask comprising at least one mask opening, at least one illumination in-coupling optical element configured to in-couple light from at least one illumination source into a light-guiding component, an image projector configured to in-couple an image and an at least one illumination source is configured to in-couple light into at least one illumination in-coupling optical element, an eyepiece, a curved light-guiding component, a light-guiding component comprising a portion of a frame, and/or two light-guiding components disposed on opposite sides of at least one out-coupling optical element.

    摘要： An authentication system includes: an imaging unit that is configure to switch between normal imaging and blur imaging that is imaging in a state of blurring with lower sharpness than that in the normal imaging; a target detection unit that detects an authentication target on the basis of a blurred image acquired by the blur imaging; a switching unit that switches the blur imaging to the normal imaging in a case where the authentication target is detected; and an authentication unit that performs authentication processing of authenticating the authentication targe on the basis of a normal image acquired by the normal imaging. According to such an authentication system, it is possible to perform the authentication processing in consideration of the privacy of the target.
