摘要

A noise reduction device includes: a saccade information obtaining unit that obtains saccade information from an electro-oculography original signal that indicates an electro-oculogram resulting from an eye movement of a user, the saccade information relating to a saccadic movement which is a rapid eyeball movement; a control unit that determines a filter property for reducing noise included in the electro-oculography original signal, on the basis of the saccade information obtained by the saccade information obtaining unit; and a filtering unit that reduces the noise included in the electro-oculography original signal using the filter property determined by the control unit, to output an electro-oculography signal.
