Title: Iris recognizer
Inventor: NAHATA KENJI
IPC: G06T1/00
Filed: 2002-04-15
Abstract: <P>PROBLEM TO BE SOLVED: To increase processing speed of an iris recognizer.  <P>SOLUTION: An image of an eye 1 picked up by an imaging element 15 is once held in an image input buffer 16 before transferred to an image storage part 20 upon instruction from a transfer control part 30. The image data DAT being transferred is passed also to a saturated pixel counting part 70, which counts saturated pixels whose luminance exceeds a threshold. If the count value CNT of the saturated pixel counting part 70 is not less than a given number after the transfer, an influence of reflection on spectacles or the like is determined to be significant and inappropriate for generation of an iris code, and lighting of a light source 12A is switched and an indicator 17 is used to notify a user so that the imaging is redone. Processing of inappropriate image data is eliminated, and total processing speed can be increased.  <P>COPYRIGHT: (C)2004,JPO
