Abstract (in Japanese) (See Japanese page) 
(in English) Recently, gaze measuring techniques have been actively studied. Non-contact gaze measuring approaches using cameras are realized by measuring the center of an iris and that of corneal curvature by image processing.
In detecting the iris, eyelids that hide the iris worsens the accuracy of the iris position. In this study, we assume that the inter-frame di?erence of the iris center position and its radius is limited. The proposed method estimate the accuracy of iris detection of both eye, and adopt better one.
