<P>PROBLEM TO BE SOLVED: To provide an eyeball movement measuring apparatus capable of accurately detecting tremor components. <P>SOLUTION: The eyeball movement measuring apparatus 1 measures the movement of a cornea 101 by imaging a cornea reflection image L2 generated by irradiating the cornea 101 with infrared light L1. The eyeball movement measuring apparatus 1 comprises: an imaging part 5 provided with a sensor part 51 including a plurality of two-dimensionally arrayed pixels, for generating imaging data including the cornea reflection image L2 made incident on the sensor part 51; a luminescent spot position computing part 6 for calculating the position of the cornea reflection image L2 in the imaging data; and a tremor signal computing part 7 for generating a third data column indicating the tremor components included in the movement of the cornea 101 by computing a difference between a first data column relating to the time change of the position of the cornea reflection image L2 and a second data column obtained by smoothing the first data column. <P>COPYRIGHT: (C)2009,JPO&INPIT |
