1. A driver imaging apparatus comprising:
- an imaging unit that captures an image of a face of a driver of a vehicle;
a first image processing unit that performs image processing on a wide portion of the face of the driver in a first image captured by the imaging unit, using the first image; and
a second image processing unit that performs image processing on a part of the face of the driver in a second image captured by the imaging unit at a higher exposure than the exposure of the first image captured by the imaging unit, using the second image.

Abstract
An imaging mechanism captures an image of a face of a driver of a vehicle. A first image processor performs image processing on a wide portion of the face of the driver in a first image using a first image captured by the imaging mechanism. A second image processor performs image processing on a part of the face of the driver in a second image captured by the imaging mechanism at a higher exposure than the exposure of the first image, using the second image.

16. A driver imaging apparatus comprising:
-
an imaging unit that captures an image of a face of a driver of a vehicle; a face direction determining unit that determines the direction in which the face of the driver is pointed in a first image captured by the imaging unit with the front of the vehicle as a reference, using the first image; and an eye information detecting for unit that i) determines the degree to which the eyes of the driver are open in a second image, which is captured by the imaging unit at a higher exposure than the exposure of the first image captured by the imaging unit, using the second image, or ii) determines the direction in which the driver is gazing in the second image, which is captured by the imaging unit at a higher exposure than the exposure of the first image captured by the imaging unit, using the second image.

17. A driver imaging method comprising:
-
performing image processing on a wide portion of a face of a driver of a vehicle in a first image, in which the face of the driver is captured, using the first image; and performing image processing on a part of the face of the driver in a second image, in which the face of the driver is captured at a higher exposure than the exposure of the first image, using the second image.

18. A driver imaging method comprising:
-
determining a direction in which a face of a driver of a vehicle is pointed in a first image, in which the face of the driver is captured, with the front of the vehicle as a reference, using the first image; and determining a degree to which the eyes of the driver are open in a second image, in which the face of the driver is captured at a higher exposure than the exposure of the first image, using the second image, or determining a direction in which the driver is gazing in the second image, in which the face of the driver is captured at a higher exposure than the exposure of the first image, using the second image.
