PROBLEM TO BE SOLVED: To reduce user's burden when correcting the gaze position of the user in an information processing system capable of inputting information by using a line of sight.SOLUTION: An information processing system includes a gaze position calculation part, a display image generation part, and a correction amount calculation part. The gaze position calculation part calculates the gaze position of an observer in the display surface of a display device by using an image including the eyeball of the observer observing the display device captured by an imaging apparatus. The display image generation part generates a second display image into which a first display image is changed on the basis of a first gaze position calculated by the gaze position calculation part for the observer, when the first display image is displayed on the display device. The correction amount calculation part calculates a correction amount with respect to the gaze position for the observer on the basis of the second gaze position calculated by the gaze position calculation part for the observer when the second display image is displayed on the display device, the change amount of the second display image with respect to the first display image, and the first gaze position.SELECTED DRAWING: Figure 4
