  • Patent number: 10768429
    Abstract: A relay lens system forms an image displayed on an image display unit as an intermediate image. A luminous flux of the image emitted from the relay lens system reflected by a half mirror is incident to a curved combiner, and the combiner reflects the incident luminous flux to the half mirror to enable an observer to observe a virtual image through the half mirror. The relay lens system forms the intermediate image at an intermediate image forming position on an optical axis before a light reflected by the half mirror is incident to the curved combiner. The distance from the optical axis of the curved combiner to a light emission surface of the relay lens system is shorter than or equal to the distance from the optical axis of the curved combiner to a maximum reflection position.

  • Patent number: 9857598
    Abstract: A display control device includes: an acquirer that receives inclination information on an occupant's head in a mobile body from a detector; and a controller that controls a displayer to generate a predetermined image representing a presentation image superimposed on an object as viewed from the occupant, based on recognition results of the object and the inclination information. When the object is recognized, with the head not inclined, the controller causes the displayer to generate a first predetermined image representing a first presentation image including one or more first lines in which a line segment connecting both ends is horizontal, or with the head inclined, the controller causes the displayer to generate a second predetermined image representing a second presentation image including a second line which is obtained by inclining at least one of the first lines by an angle according to the inclination of the occupant's head.
