PUPIL SIZE MODELING DEVICE AND METHOD FOR MODELING OF PUPIL SIZE

摘要

PURPOSE: A pupil size modeling device and a method thereof are provided to supply a variation for a pupil size in a brightness and light adaptation situation which gradually changes as a generalized formula, thereby supplying information for a stimulus suggestion system. CONSTITUTION: A brightness providing unit(130) gradually provides changed brightness to a user. A detecting unit(140) detects a pupil size of the user according to the brightness. A formula generating unit(150) generates a generalized formula for a variation of the pupil size based on the detected pupil size. The brightness providing unit gradually provides the brightness which successively decreases to a size of a predetermined level.
