PROBLEM TO BE SOLVED: To propose a useful binoculars display device.SOLUTION: A binoculars display is provided that comprises binoculars display systems receiving image information from binoculars imaging system with optical axes in parallel, and having an optical axis width equivalent to an optical axis width of the binoculars imaging systems. The binoculars display is configured to provide a display virtual image at a distance equivalent to a reference subject distance of the binoculars imaging system. The binoculars display comprises a diopter adjustment function, and includes an image enlargement function or image contraction function. The binoculars display is provided that comprises: binoculars display system receiving the image information from the binoculars imaging systems with the optical axes in parallel, and having an optical axis width different from that of the binoculars imaging system； and an image shift function based on a difference between the optical axis width of the binoculars imaging system and the optical axis width of the binoculars display system. The binoculars display is provided that comprises: binoculars display systems including an optical axis width adjustment function； and an image shift function in accordance with an optical axis width adjustment in the binoculars display system. The binoculars display is provided that comprises: display optical systems receiving the image information from the binoculars imaging systems with the optical axes in parallel, and being different from the binoculars imaging systems； and an image shift function based on a difference of the display optical system.SELECTED DRAWING: Figure 11【課題】有用な双眼ディスプレイ装備を提案する。【解決手段】光軸が平行な双眼撮像系から画像情報を受けると共に、双眼撮像系の光軸幅と同等の光軸幅を有する双眼表示系を備えた双眼ディスプレイを提供する。双眼撮像系の標準被写体距離と同等の距離に表示虚像を提供する。視度調節機能を備える。画像拡大機能又は画像縮小機能を有する。光軸が平行な双眼撮像系から画像情報を受けると共に、双眼撮像系の光軸幅と異なる光軸幅を有する双眼表示系と、双眼撮像系の光軸幅と双眼表示系の光軸幅の差に基づく画像シフト機能を有する双眼ディスプレイを提供する。光軸幅調整機能を備えた双眼表示系と、双眼表示系における光軸幅調整に応じた画像シフト機能を有する双眼ディスプレイを提供する。光軸が
