摘要： An image forming apparatus includes an optical scanning device including a light source element configured to radiate a light beam, an optical deflector configured to deflect the light beam two-dimensionally, and a target scanning surface that is transparent and having a two-dimensional image formed thereon by the light beam deflected from the optical deflector, and a projection optical system including a convex mirror and configured to enlarge and project the two-dimensional image on a target projection surface. The target projection surface includes a reflection surface of a half mirror. The half mirror is positioned outside of the image forming apparatus and configured to transmit a part of a light incident on the half mirror and reflect another part of the light incident on the half mirror.

摘要： An information processing apparatus includes a projection information acquisition unit (31, 2, 3, 7) to obtain, from a storage unit (50, 6), projection information based on information on a position of a user. The information on the position of the user is obtained by an information acquisition unit (20, 2, 3) worn by the user. The projection information is to be projected by a projection unit (40, 3) worn by the user. The information processing apparatus includes a projection destination information acquisition unit (33, 2, 3, 7) to obtain projection destination information. The projection destination information is information on a projection destination onto which the projection information is to be projected, and a control unit (34, 2, 7) to cause the projection unit (40, 3) to project the projection information onto the projection destination based on the projection information and projection destination information.

摘要： A communication terminal (3a, 3b, 3c, 3d) displays thumbnails for predetermined-region images in a panoramic image and accepts a selection of a predetermined thumbnail so as to display the predetermined-region image corresponding to the accepted thumbnail. This brings about an effect that a user can easily find a desired panoramic image or a desired predetermined-region image in the panoramic image.
