SYSTEM FOR ANALYZING EYE RESPONSES TO ACCURATELY DETECT DECEPTION
First Claim
1. A Deception Detection System for automatically identifying a subject'"'"'s attempt at deception in response to being presented with a set of questions by an examiner, comprising:
- image means for generating a time-wise sequence of digital images of at least one of the subject'"'"'s eyes, said sequence of digital images being of duration at least sufficient to include the time when said subject is being presented with a question by an examiner and when said subject is answering said question;
digital image processing means for computing a size of a pupil of at least one of said subject'"'"'s eyes in said plurality of said digital images in said sequence of digital images; and
deception determining means, responsive to said determined size of said pupil in said plurality of said digital images in said sequence of digital images, for determining whether said subject is attempting to provide a deceptive answer to said question.

Abstract
The present system for analyzing eye responses to automatically detect deception obtains a series of digital image frames from a headset. This system precisely controls the illumination generated by the headset to bias the subject'"'"'s pupils and automatically and precisely determine the subject'"'"'s pupil location, size, and responsiveness. These measurements enable the system for analyzing eye responses to automatically detect deception by accurately measuring the subject'"'"'s involuntary pupillary responses to questions posed by an examiner. These measurements can be used exclusively or in combination with one or more of the standard elements of the polygraph machine to automatically detect deception.
