PROBLEM TO BE SOLVED: To provide an imaging system and endoscope capable of acquiring an image in which luminance unevenness is suppressed.SOLUTION: An imaging system comprises: an imaging element including a light receiving unit in which a plurality of pixels each of which performs photoelectric conversion on received light to generate an electric signal are arranged in a matrix shape and a reading unit for sequentially reading, for each line, electric signals generated by the plurality of pixels a light source unit for emitting illumination light transmissivity change means that is provided on a light path of the illumination light and is capable of changing transmissivity of the illumination light a timing detection unit for detecting exposure timing at which all of at least reading target pixels can be exposed and an illumination timing setting unit for setting illumination timing by the illumination light on the basis of exposure timing detected by the timing detection unit. The transmissivity change means changes transmissivity on the basis of the illumination timing set by the illumination timing setting unit.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】輝度ムラを抑制した画像を取得することができる撮像システムおよび内視鏡を提供すること。【解決手段】本発明にかかる撮像システムは、各々が受光した光を光電変換して電気信号を生成する複数の画素がマトリックス状に設けられた受光部と、複数の画素が生成した電気信号をラインごとに順次読み出す読出し部と、を有する撮像素子と、照明光を出射する光源部と、照明光の光路上に設けられ、照明光の透過率を変更可能な透過率変更手段と、少なくとも読み出し対象のすべての画素を露光することが可能な露光タイミングを検知するタイミング検知部と、タイミング検知部が検知した露光タイミングをもとに、照明光による照明タイミングの設定を行う照明タイミング設定部と、を備え、透過率変更手段は、照明タイミング設定部が設定した照明タイミングに基づき透過率を変更する。【選択図】図2
