[Problem] To enlarge a range wherein it is possible to detect corneal reflected light by preventing a situation in which it is not possible to acquire an image of the corneal reflected light owing to such factors as a rotation angle of a subjects eyeball. [Solution] Provided is a cornea center detection device, in which a first camera and a second camera are positioned in mutual proximity, and a first light source and a second light source are positioned at a mutual remove such that emission lights respectively therefrom enter the subjects eye at different positions. Further, the cornea center detection device comprises: a corneal reflected light detection unit which detects corneal reflected light in images which the first camera and the second camera have acquired a cornea center computation unit which computes a cornea center on the basis of the images which the first camera and the second camera have acquired and a light source control unit which switches the driving of the first light source and the second light source. With regard to the detection which is performed by the corneal reflected light detection unit, the light source control unit interrupts the driving of either of the first light source and the second light source and causes the driving of the other thereof, if the corneal reflected light has not been detected in the images which the first camera and the second camera have acquired.Lobjectif de linvention est dagrandir une plage dans laquelle il est possible de détecter une lumière reflétée par la cornée en empêchant une situation dans laquelle il est impossible dacquérir une image de la lumière reflétée par la cornée grâce à des facteurs tels que langle de rotation du globe oculaire dun sujet. Pour ce faire, linvention concerne un dispositif de détection du centre de la cornée dans lequel une première caméra et une seconde caméra sont positionnées à proximité lune de lautre, et une première source lumineuse et une seconde source lumineuse sont po
