1. An observation system that enables an optical image which is observable from a predetermined observation position and a display image of a display to be simultaneously visible by superimposing the display image on the optical image, the system comprising:
a processor configured to perform a control of sequentially changing a display position of the display image on the display in a first range; and
an imager comprising an imaging element that captures a part of the optical image,
wherein a width of a maximum portion of the first range which has a maximum length in a moving direction of the display position is equal to or less than a tolerance between a range of the display image of the display corresponding to an imaging range of the imaging element and the imaging range of the imaging element that captures the part of the optical image, and a contrast caused by movement of the display position of the display image is set to a width that is unable to be discriminated based on a visual characteristic by a human eye.
