Claim 13:
14. A non-transitory computer-readable storage medium storing a program for causing a computer to execute operations comprising:
acquiring information corresponding to an observation position of an observer at a plurality of different timings, wherein the information indicates a shift in the observation position; and
controlling a display unit to display an indicator corresponding to the observation position,
wherein the information is acquired by repeatedly detecting and accumulating the observation position at the plurality of different timings,
wherein, in the controlling, in a case where a change of the observation position is continuously smaller than a first threshold fora first number of the different timings, the display position of the indicator is not shifted, and
wherein in a case where the change of the observation position is continuously greater than a second threshold for a second number of the different timings, the display position of the indicator is shifted, and
wherein at least one of the first number of the different timings and the second number of the different timings is changed in accordance with at least one of a line-of-sight characteristic of the observer, a viewing state of the display unit, and a manual operation by the observer.
