1. A head-mounted display, comprising:

  • a display unit that is configured to be mountable on a head of a user and is capable of providing the user with a field of view of a real space;

    a detector that detects an azimuth of the display unit around at least one axis;

    a region limiter that is capable of limiting a display region of the field of view along a direction of the one axis in three-dimensional coordinates surrounding the display unit;

    a storage unit that stores images that should be displayed in the field of view with the images being made corresponding to the three-dimensional coordinates;

    a display control unit that displays, based on an output of the detector, an image in the three-dimensional coordinates, which corresponds to the azimuth, in the field of view; and

    a second control unit including an image acquisition unit that acquires a plurality of images stored in the storage unit,wherein the region limiter, the storage unit, and the display control unit constitute a first control unit, and the first control unit is configured to request the second control unit to preferentially transmit an image made corresponding to a coordinate position closer to the display region of the field of view in the three-dimensional coordinates.
