PROBLEM TO BE SOLVED: To simultaneously satisfy acquisition of high-resolution, high-precision depth information and a reduction in the diameter of the distal end of an endoscope.SOLUTION: Provided is an endoscope apparatus, comprising: an irradiation part that irradiates a subject with illumination light and with a structured pattern for acquiring depth information of the subject； and an acquisition part that acquires reflected light of the light irradiated by the irradiation part. With this configuration, it is possible to simultaneously satisfy acquisition of high-resolution, high-precision depth information and a reduction in the diameter of the distal end of an endoscope.SELECTED DRAWING: Figure 1【課題】高解像、高精度な奥行情報の取得と、内視鏡先端の細径化を同時に満たすこと。【解決手段】被写体に照明光を照射するとともに、被写体の奥行情報を取得するための構造化パターンを照射する照射部と、前記照射部により照射された光の反射光を取得する取得部と、を備える、内視鏡装置が提供される。この構成により、高解像、高精度な奥行情報の取得と、内視鏡先端の細径化を同時に満たすことが可能となる。【選択図】図１
