PROBLEM TO BE SOLVED: To increase the resolution of an image when the image is picked up by an image sensor having a light receiving sensitivity in a long wavelength region. A surgical imaging system according to the present disclosure has a first image sensor that has a light-receiving sensitivity in a visible light wavelength range and that images a surgical site, and a visible light and near-infrared light wavelength range. A second image sensor having a sensitivity and for imaging the surgical site, a first image captured by the first image sensor, and a second image captured by the second image sensor are displayed. And a signal processing device that performs processing for. [Selection diagram] Figure 1【課題】長波長域に受光感度を有するイメージセンサで撮像した場合に、画像の解像度を高める。【解決手段】本開示に係る手術用撮像システムは、可視光の波長域に受光感度を有し、術部を撮像する第１のイメージセンサと、可視光及び近赤外光の波長域に受光感度を有し、前記術部を撮像する第２のイメージセンサと、前記第１のイメージセンサで撮像された第１の画像と前記第２のイメージセンサで撮像された第２の画像を表示するための処理を行う信号処理装置と、を備える。【選択図】図１
