1. A head-mounted display device comprising:
a first camera provided on a front surface;
a projector provided on the front surface and configured to project a pattern image onto an imaging range of the first camera;
a second camera provided on a side surface; and
one or more processors and/or circuitry configured to
execute a first acquisition processing of acquiring first information on a state including at least one of a position and an orientation of the head-mounted display device by detecting features of a real space from an image captured by the first camera;
execute a second acquisition processing of acquiring second information on the state by detecting features of the real space from an image captured by the second camera; and
execute a generation processing of generating an image of a virtual object, based on the first information and the second information, wherein
in the second acquisition processing, the second information is acquired by detecting the features of the real space from an image in which the pattern image does not appear.
