The present invention provides a face image processing apparatus capable of preventing the error extraction of the eye when extracted, and improving reliability in the open/close detection through a two-dimensional feature of the eye area. This face image processing apparatus comprises: a camera (2) for inputting a face image of a person to be detected (1); a multi-valued image memory (3) for temporarily storing the light and shade image obtained by the camera (2); binarization means (4) for binarizing the light and shade image outputted from the multi-valued image memory (3); a binary image memory (5) for temporarily storing the binary image obtained by the binarization means (4); feature extraction means (6A) for extracting a naris binary area from the binary image outputted from the binary image memory (5), and for extracting an eye binary area from the binary image outputted from the binary image memory (5) using the naris binary area as reference; and open/close detection means (7A) for detecting the opening/closing states of the eye based on the shape feature of the eye binary area.

1. Field of the Invention
The present invention relates to a face image processing apparatus for an eyewink detection, including extracting naris areas, which is relatively easy to be extracted, through image processing, then estimating the position of eyes based on the position of nares to extract eye areas, and detecting opening/closing states of the eyes from shape features of the eye areas.
