The objective of the present invention is to identify objectively and quantitatively a time filter related to vision, non-invasively employing an oculomotor reflex. In the present invention, an initial image having a uniformly constant brightness, a first stimulation pattern image having a mean brightness the same as the initial image, and a second stimulation pattern image which induces apparent movement together with the first stimulation pattern image, are presented sequentially, while eye movement is measured during a fixed period while the second stimulation pattern image is being presented and is stored in association with the duration for which the first stimulating pattern image used during the measurement was presented. At this time, a setting of the duration for which the first stimulating pattern image used in each trial is presented is changed. Parameter values of an oculomotor reflex kinetic energy model are optimized in order to minimize the difference between a measured waveform specified in accordance with changes in a sight line direction, calculated for each presentation duration, and a simulation result calculated by inputting the first stimulating pattern image and the second stimulating pattern image into the kinetic energy model, and a time filter unique to an inspection target is calculated.La présente invention a pour objectif d'identifier objectivement et quantitativement un filtre temporel lié à la vision, utilisant un réflexe oculomoteur de manière non effractive. Selon la présente invention, une image initiale d'une luminosité uniformément constante, une première image de modèle de stimulation d'une luminosité moyenne identique à l'image initiale, et une seconde image de modèle de stimulation induisant un mouvement apparent conjointement avec la première image de modèle de stimulation, sont présentées séquentiellement, tandis que le mouvement de l'œil est mesuré pendant une période fixe pendant que la seconde image de modèle de stimulatio
