An imaging system 10 includes a control unit 15. An imaging device 20 and an information processing device 60 include a fixed state in which the devices are fixed to each other, and a separated state in which the devices are separated from each other. The control unit 15 correlates disturbance information, which indicates disturbance affecting image data or audio data generated by the imaging device 20, with image data generated by the imaging device 20 at the time of disturbance on the basis of fixation/separation information indicating the fixed state or the separated state of the imaging device 20 and the information processing device 60. Accordingly, a low-quality portion in a captured image is easily detectable on the basis of disturbance information correlated with image data.
