Abstract
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.

15. An in-vehicle image processing device comprising:
-
face image receiver which receives a picked-up image including a face of a driver from a camera; face area detector which analyzes the image which is received by the face image receiver, and detects an area of a face which is included in the image; brightness determiner which determines brightness of the face area which is detected by the face area detector; camera controller which controls the camera in order to make brightness of a face area to be a predetermined level based on the brightness of the face area which is acquired by the brightness determiner; and condition determiner which determines a condition of a driver using an image of a face area that the brightness of the face area which is detected by the face area detector is a predetermined level, and wherein the camera periodically picks up an image of a driver and provides the picked-up image to the face image receiver, and the camera controller controls an exposure amount of the camera in accordance with brightness determined by the brightness determiner. - View Dependent Claims (16, 17, 18, 19)
