PUPIL DETECTOR AND IRIS IDENTIFICATION DEVICE

摘要

A pupil detector comprises image data extracting section (220) for setting concentric integration circles on an eye image and extracting image data on the eye image present on the circumferences of the integration circles, a go-around integration section for integrating the image data along the circumference of each integration circle, and a pupil position detecting section or detecting the center coordinates of the integration circles as the pupil position coordinates such that the integral calculated by the go-around integration section varies stepwise with respect to the radius of each integration circle. The image data extracting section (220) has randomly-accessible line memories (224<sub
