SYSTEM FOR MEASUREMENT OF EYE POSITION IN CLOSED STATE OF EYES

摘要

PROBLEM TO BE SOLVED: To provide a system 100 for measurement of eye position which accurately measures a visual line angle simultaneously with brain function measurement using fMRI while the eyes of a subject M are closed or the subject M is asleep.

SOLUTION: The system for measurement of eye position comprises a correlation data calculation section for calculating correlation data that shows correlation between a visual line angle and surface image related data, and a visual line angle calculation section 51 for calculating a visual line angle of a subject M when the eye is imaged on the basis of the correlation data and surface image related data acquired by imaging the eyelids of the subject M when the eye is closed by means of an optical imaging apparatus 2 separately from imaging at each point for acquiring the surface image related data used for calculating the correlation data.
