Publication number: 20220139112Abstract: A controller controls the readout of an image from iris image pick-up devices for performing image pick-up of an iris of a subject. In the control of the readout of an image from the iris image pick-up devices, the controller sets a region of interest to be treated as a target of the image readout. The controller stores past information, and in the case of performing image processing on the same subject, the controller determines whether or not an eye region of the subject was successfully covered by the region of interest used in the past. In the case of determining that the eye region of the subject was not successfully covered, the controller corrects the readout of an image from the iris image pick-up devices.Type: ApplicationFiled: February 12, 2020Publication date: May 5, 2022Applicant: NEC CorporationInventors: Keiichi CHONO, Chisato FUNAYAMA, Masato TSUKADA
