An image capturing system includes an image capturing terminal and an external terminal communicating with the image capturing terminal. Either the image capturing terminal or the external terminal includes a terminal information acquisition unit having a sensor and acquiring the position of the local terminal and the image capturing direction of the image capturing terminal from the sensor; and a calculation unit calculating a relative positional relationship between a subject and the local terminal. The image capturing system includes an instruction unit instructing a correction of the position of the local terminal or the image capturing direction of the image capturing terminal based on calculation result information indicating a calculation result of the relative positional relationship calculated by the calculation unit.
