摘要： A black eye position existence probability density distribution learning unit that records a black eye position which is detected in the daytime to a black eye position existence probability density distribution, a red-eye candidate detection unit that detects red-eye candidates from the image of the driver at night, and a red-eye determination unit that determines the red eye from the red-eye candidates. The red-eye determination unit determines the red eye on the basis of the relationship between a change in the direction of the face and the behavior of the red-eye candidate and determines, as the red eye, the red-eye candidate disposed at the position of high black eye position existence probability density with reference to the black eye position existence probability density distribution.

摘要： An ECU which is connected to an image sensor and an illuminance sensor includes an eyelid detection unit that detects the positions of the upper and lower eyelids from a face image, an eyelid determination unit that determines the positions of the upper and lower eyelids detected by the eyelid detection unit, and an eye opening degree calculation unit that calculates the degree of eye opening. The eyelid determination unit searches for a red-eye candidate in the range in which the skin is assumed to be present from the positions of the upper and lower eyelids detected by the eyelid detection unit. When the red-eye candidate is searched in the range, the eyelid determination unit determines that the eyelid detection unit falsely detects the positions of the upper and lower eyelids.

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.
