摘要： An imaging apparatus for taking an image of a face includes an imaging element having sensitivity for a near-infrared range and a visible range, a first optical filter provided between the face and the imaging element to reduce an intensity of a visible light entering the imaging element and a near-infrared light irradiating portion for irradiating the face with a near-infrared light.

摘要： Light reflected by glasses etc. worn by a driver picked up in a facial image of the driver is reduced. With a vehicle-mounted camera (1) equipped with a first LED illuminating device (12) and a second LED illuminating device (13), each illuminating device is lit up alternately in synchronism with times of photographing facial images and facial images of the driver are taken at each lighting time. The vehicle-mounted camera then compares brightness for each pixel positioned at the same relative positions on each photographed facial image and extracts pixels of low brightness. The vehicle-mounted camera then generates new facial images for transmission to an ECU by synthesizing each of the extracted pixels. The ECU on the receiving side then detects inattentive driving etc. by the driver based on the facial images.

摘要： Every time a camera transmits a picked-up face image to an ECU, the ECU detects a face area from the transmitted face image, and corrects an exposure time so as to have brightness most appropriate to determine a facial direction and the condition of eyes at the detected face area. The corrected exposure time is notified to the camera, and the camera picks up an image of the face of a driver at the notified exposure time. Accordingly, the ECU analyzes a face image which is periodically picked up with the most appropriate brightness regardless of a change in an environment, and determines whether or not a driver is doing a hazardous driving.
摘要翻译： 每当相机将拾取的面部图像发送到ECU时，ECU从所发送的脸部图像检测面部区域，并且校正曝光时间，以便具有最适合的亮度以确定面部方向和眼睛的状况 检测到的脸部区域。 将修正的曝光时间通知相机，并且照相机以通知的曝光时间拾取驾驶员的脸部的图像。 因此，ECU分析与环境变化无关地以最合适的亮度周期性地拾取的面部图像，并且判断驾驶员是否进行危险驾驶。

摘要： There are provided a face image pickup device and a face image pickup method which can stably acquire a face image by appropriate illumination, and a program thereof. The face image pickup device comprises a camera which picks up an image of a face of a target person, an illumination light source which illuminates the face of the target person with near-infrared light having an arbitrary light amount, and a computer. The computer detects an area including an eye from the face image of the target person picked up by the camera. The computer measures a brightness distribution in the detected area. Thereafter, the computer controls the illumination light source so as to change the amount of near-infrared light based on the measured brightness distribution.
