20090103048 | METHOD AND SYSTEM FOR PUPIL DETECTION - A method for detecting a location of a pupil. The method involves projecting a modulated light at a first phase towards a face from a lighting source located near an optical axis of a modulated light camera, concurrently projecting a modulated light at a second phase towards the face from a lighting source located off the optical axis of the modulated light camera, where the first phase and the second phase are different; receiving a light reflected from the face; and generating an image from the light reflected from the face, where the image indicates the location of the pupil. | 04-23-2009 |
