Title:
露出制御装置
Document Type and Number:
Japanese Patent JP5375814
Kind Code:
B2
Abstract:
The exposure control apparatus is for performing exposure control for a camera mounted on a vehicle in accordance with brightness of a recognition area set in an image ahead of the vehicle taken by the camera. The exposure control apparatus includes a measuring means for measuring brightness of a photometric area showing a landscape more distant from the vehicle than a landscape shown by the recognition area in each of images successively taken by the camera, a detection means for detecting brightness variation with time of the photometric area based on measurement results by the measuring means for images taken by the camera at different times, and a control means configured to predict a timing at which the brightness of the recognition area changes based on the brightness variation with time of the photometric area, and perform exposure control of the camera at the predicted timing.
