Provided is an information processing device which is provided with a detection unit for detecting a corneal reflection image corresponding to light emitted from a light source and reflected by the cornea from captured images in which an eye irradiated with light from the light source is captured. The detection unit estimates an eyeball center position on the basis of a plurality of time-series captured images, estimates a corneal center position on the basis of the estimated eyeball center position, estimates a candidate position of a corneal reflection image on the basis of the estimated corneal center position, and detects the corneal reflection image from the captured images on the basis of the estimated candidate position of the corneal reflection image.
