PROBLEM TO BE SOLVED: To correct an image signal captured by an endoscope device based on an angular speed of a head part.SOLUTION: An endoscope system includes: an endoscope device having a lens barrel part including an objective lens, and a head part, in which a gyro part for detecting movement of the head part is provided in the head part and an image processing device comprising a correction part which, based on movement of an image corresponding to an image signal input from the endoscope device and the movement of the head part detected by the gyro part, generates a deflection correction image signal in which deflection of the image signal is corrected. The present disclosure can be used, for example, for laparoscopic surgery.SELECTED DRAWING: Figure 2
