1. A gaze estimation system comprising:
at least one memory storing instructions; and
at least one processor that is configured to execute instructions to:
allow a point to look at where a target person looks at to be displayed to move in a predetermined moving aspect;
detect a movement of eyes of the target person from an image of the target person;
determine whether or not the eyes of the target person are following the point to look at on the basis of a relationship between the eye movement and a movement of the point to look at;
calculate a parallax that is a difference between a position of the point to look at and a point of gaze of the target person, from the detected eye movement of the target person,
calculate a time delay of the parallax from the parallax calculated in a state where the point to look at is moving,
calculate a deviation amount of the estimated point of gaze with respect to a true value on the basis of the parallax and the time delay of the parallax, and
determine a correction value for correcting the point of gaze of the target person on the basis of the deviation amount; and
correct a parameter related to the detected eye movement of the target person when the eyes of the target person are following the point to look at.
