Abstract: An endoscope system includes an insertion portion, a support portion, a first subject image acquisition portion, a second subject image acquisition portion, a third subject image acquisition portion, an image generation section, and an image processing section. The image processing section can switch between a first mode of arranging lateral images around a forward image in a continuously connected state and a second mode of arranging the lateral images and the forward image in a separated. The image processing section continuously connects a third image in a non-display region to the forward image in the first mode, and arranges the lateral images side by side with both sides of the forward image and arranges the third image adjacent to the forward image in the second mode.
