PROBLEM TO BE SOLVED: To reduce interference of halation due to regular reflection during an endoscopic observation.SOLUTION: The endoscopic system includes an endoscope including: a light source of illumination light that illuminates inside of a test subject an illumination light exit, from which the illumination light is emitted and an objective optical system configured to form an image of the inside of the test body illuminated by the illumination light. The endoscopic system further includes: regular reflection light detection means configured to detect halation due to the regular reflection in an image formed by the objective optical system and illuminance distribution changing means configured to change illuminance distribution of the illumination light when the halation due to the regular reflection is detected.COPYRIGHT: (C)2014,JPO&INPIT【課題】内視鏡観察において正反射による白飛びの妨害感を低減させる。【解決手段】被検体の内部を照射する照明光の光源と該照明光を照射する照明光出口と、該照明光で照射された被検体内部を撮像する対物光学系とを備える内視鏡を有する内視鏡システムにおいて、該対物光学系により撮像された像における正反射による白飛びを検知する正反射光検知手段と、正反射による白飛びが検知された場合に該照明光の照度分布を変更する照度分布変更手段とを備えることを特徴とする、内視鏡システム。【選択図】図3
