摘要

PPROBLEM TO BE SOLVED: To provide an eye potential measuring device which estimates a drift component that is baseline variation from eye potential original signals of a user to output eye potential signals in which the influence of a drift is eliminated. PSOLUTION: The eye potential measuring device 100 includes: an eye potential measurement unit 110 to measure eye potential original signals; a visual field imaging unit 150 for capturing visual field images; a drift estimation processing unit 190 for estimating drift signals; and a subtractor 120 for subtracting a drift signal from the eye potential original signals and outputting the eye potential signal. The drift estimation processing unit 190 includes: an eye potential variation calculation unit 140 for calculating eye potential variation; a vector detection unit 160 for detecting the movement vector of a moving object included in the visual field image; a drift variation estimation unit 170 for estimating a drift variation when variation in a visual line follows movement of a moving object, and a drift estimation unit 180 for adding the drift variation to a past drift signal to estimate the drift signal.
