ABSTRACT:
A face image processing apparatus for use in a sleep-inhibition security system for car drivers is disclosed. The apparatus includes an input section for acquiring an input face image of a target person, an eye extraction region setter for determining an eye extraction region within the input face image, and an extractor for extracting from the eye extraction region first and second image components corresponding to an eyebrow image and an eye image respectively. A first detector is adapted to detect relative positions of the first and second image components extracted. A second detector is provided for detecting the open or closed state of at least one eye image by analyzing variations in the relative positions detected.
