PROBLEM TO BE SOLVED: To enable a plurality of light source devices and a plurality of imaging devices to operate in synchronization with each other at predetermined timings during medical treatment such as microscopic surgery or endoscopic surgery, and to support output of stereoscopic images of good image quality. To do. An imaging system includes first and second light source devices that respectively illuminate a subject with light having different wavelength bands, first and second imaging devices that respectively image the subject, and imaging of the subject. First and second video processing devices for processing a video and outputting it to an output unit. Based on the genlock signal, the first and second light source devices are alternately turned on in synchronization with the frame period of the captured image or every integral multiple thereof. The first imaging device images in synchronization with lighting of each of the first and second light source devices, and the second imaging device images in synchronization with lighting of each of the first and second light source devices. To do. [Selection diagram] Fig. 4【課題】顕微鏡手術あるいは内視鏡手術等の医療行為の際に、複数の光源装置および複数の撮像装置をそれぞれ既定のタイミングで同期して動作可能とし、良好な画質の立体映像の出力を支援する。【解決手段】撮像システムは、波長帯が異なる光で被検体をそれぞれ照射する第１および第２の光源装置と、被検体をそれぞれ撮像する第１および第２の撮像装置と、被検体の撮像映像を処理して出力部に出力する第１および第２の映像処理装置とを備える。第１および第２の光源装置は、ゲンロック信号に基づいて、撮像映像のフレーム周期またはその整数倍ごとに同期して交互に点灯する。第１の撮像装置は、第１および第２の光源装置のそれぞれの点灯に同期して撮像し、第２の撮像装置は、第１および第２の光源装置のそれぞれの点灯に同期して撮像する。【選択図】図４
