    摘要： An image around a vehicle matching the intent of a driver is automatically displayed.An infrared camera (2) picks up an image of the face of a driver (7). A visual line direction and a face direction are detected from the face image of the driver (7). Based on the visual line direction of the driver (7) and the face direction thereof, a direction in which the driver (7) gazes is detected. When the direction in which the driver (7) gazes is included in image pickup ranges of CCD cameras (1A, 1B, and 1C), an image around a vehicle (100) picked up by any one of the CCD cameras (1A, 1B, and 1C) is automatically displayed on a monitor (6).

    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： 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.
