The object to be detected (1) is obtained by obtaining a facial image processing apparatus capable of accurately extracting the retinal reflection image and accurately determining the open / closed state of the eyes, regardless of reflection images such as glasses existing around the retinal reflection image. Illumination means 11 for irradiating the face of the person, photographing means 10 for photographing the face image of the detection subject 1, binarization means 21 for binarizing the shaded image, and binarization bag And a feature extracting means 23 for extracting a pixel region, and an opening and closing judging section 24 for judging the state of the eyes of the detection subject l. The retinal reflex image candidate region is used as a candidate region, and the current screen candidate and the front screen candidate are added to distinguish and extract the retinal reflection image and the reflective image from the attributes of the front screen to suppress false detection of the reflected image, and at the same time, the left and right eyes Relative to Create a retinal reflection phase candidate by the relation, and by complementary with these two extraction means, regardless of the reflection of glasses, etc. existing on the peripheral retinal reflection, and extracts the phase precision allows retinal reflection.
