To measure a distance to a subject by improving processing efficiency without complicating adjustment and configuration.SOLUTION: A distance measurement apparatus 1 comprises: a prism 11 which has a first incidence surface 11a and a second incidence surface 11b on which light from a subject 100 is incident from two different directions, and which emits incident first light and second light from the first incidence surface 11a and second incidence surface 11b; a lens 12 which collects the incident first light and second light from the prism 11 to emit the light; a first imaging element 13 which generates a first image by imaging the first light and a second imaging element 14 which generates a second image by imaging the second light, the first imaging element and the second imaging element being arranged side by side so as to be opposed to an emission surface 12b of the lens 12 and imaging the first light and second light from the lens 12 in mutually different framing; and a distance measuring unit 25 which calculates a distance to the subject 100 on the basis of the first image and second image.SELECTED DRAWING: Figure 1 【課題】調整や構成を複雑にすることなく、処理効率を向上して、被写体までの距離を測定する。【解決手段】距離測定装置１は、被写体１００からの光を異なる２方向からそれぞれ入射する第１入射面１１ａ及び第２入射面１１ｂを有し、第１入射面１１ａ及び第２入射面１１ｂから第１光及び第２光を入射して出射するプリズム１１と、プリズム１１から第１光及び第２光を入射、集光して出射するレンズ１２と、レンズ１２の出射面１２ｂに対向して並んで配置され、レンズ１２からの第１光及び第２光をそれぞれ異なるフレーミングで撮像し、第１光を撮像して第１画像を生成する第１撮像素子１３及び第２光を撮像して第２画像を生成する第２撮像素子１４と、第１画像と第２画像とに基づいて、被写体１００からの距離を算出する距離測定部２５と、を備える。【選択図】図１
