摘要： Detecting with good precision an eye inside corner position and an eye outside corner position as face feature points even when the eye inside corner and/or the eye outside corner portions are obscured by noise. First eyelid profile modeling is performed with a Bezier curve expressed by a fixed control point P3 indicating an eye inside corner first position detected in an image, a fixed control point P4 indicating an eye outside corner first position, a control point P1 corresponding to an upper eyelid position candidate (first parameter), and a control point P2 corresponding to a lower eyelid position candidate (second parameter). Then in a second eyelid profile model with fixed P1 and P2 of the first eyelid profile model having the highest fitting evaluation value λ to the eyelid profile in the image, the values of a control point P3 indicating an eye inside corner position candidate (third parameter) and a control point P4 indicating an eye outside corner candidate (fourth parameter) at a maximum of a fitting evaluation value λ when changing the values of the control point P3 and control point P4 are determined as an eye inside corner second position and an eye outside corner second position, respectively.

摘要： A computer (30) obtains a facial image acquired by picking up an image of a person subjected to image pickup from a camera (10), and estimates a facial expression of the person subjected to image pickup based on the obtained facial image. Next, the computer obtains an eye open level of the person subjected to image pickup based on the facial image, and sets a threshold of the eye open level based on the estimated facial expression of the person subjected to image pickup. When the eye open level exceeds the threshold, the computer (30) determines that the eye of the person subjected to image pickup is opened. Moreover, when the eye open level does not exceed the threshold, the computer determines that the eye of the person subjected to image pickup is closed.

摘要： An eye part detecting device has an image input section (21) for acquiring a face image, an eyelid edge labeling section (24) for detecting upper eyelid candidates and lower eyelid candidates which satisfy predetermined conditions for upper eyelids or lower eyelids in the face image, and an eyelid determination section (27) for comparing combinations of the upper and lower eyelid candidates to determine the combination of the upper and lower eyelid candidates whose relation best satisfies a predetermined condition as the upper and lower eyelids. The eyelid edge labeling section (24) classifies the horizontal edges and vertical edges calculated by an edge calculating section (23) into the upper eyelid candidates and the lower eyelid candidates according to a degree of how well the predetermined conditions are satisfied. A lower eyelid candidate evaluating section (26) may be provided for excluding a lower eyelid candidate when it has at least one horizontal edge present in a lateral direction of the lower eyelid candidate. A lower eyelid candidate discriminating section (25) may be provided for discriminating that of the lower eyelid candidates whose vertical edge does not satisfy the predetermined condition as a lower eyelid preliminary candidate.
