PROBLEM TO BE SOLVED: To provide an imaging system capable of preventing image quality from deteriorating even though a series of processing between exposure of an imaging element and the read-out of electric charge is performed in each line at different timing.SOLUTION: The imaging system includes an illumination control part 32 for making an illumination part 31 execute a series of processing which makes the illumination part 31 emit first illumination light for a first period, makes the illumination part 31 emit second illumination light having a wavelength band different from that of the first illumination light during a second period after the end of the first period, and makes the illumination part 31 emit the first illumination light during a third period after the end of the second period, and an image processing part 402 for generating a monochrome color signal corresponding to different illumination light (illumination light during the second period) by subtracting third imaging signal in a third period from an addition signal obtained by adding a first imaging signal in the first period and a second imaging signal in the second period.COPYRIGHT: (C)2015,JPO&INPIT【課題】撮像素子で露光してから電荷を読み出すまでの一連の処理をライン毎に異なるタイミングで行ったとしても、画質が低下することを防止することができる撮像システムを提供する。【解決手段】第1の期間、照明部31に第1の照明光を出射させ、第1の期間の終了後、第2の期間、第1の照明光と波長帯域が異なる第2の照明光を照明部31に出射させ、第2の期間の終了後、第3の期間、第1の照明光を照明部31に出射させる一連の処理を照明部31に実行させる照明制御部32と、第1の期間における第1の撮像信号と第2の期間における第2の撮像信号とを加算した加算信号から第3の期間における第3の撮像信号を減算することによって、異なる照明光(第2の期間の照明光)に対応する単色の色信号を生成する画像処理部402と、を備える。【選択図】図2
