Title:
CAMERA EXPOSURE SETTING DEVICE AND CAMERA EXPOSURE SETTING PROGRAM
Document Type and Number:
Japanese Patent JP2014135613
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an exposure setting device capable of obtaining a proper camera exposure even if a position and an angle of a camera change.SOLUTION: A position of not-detection object to not be detected in an image obtained by an on-vehicle camera 10 in which an exposure control parameter can be set therein, is detected by a millimeter wave radar 20. In an image processing part 30, a plurality of image areas corresponding to an area other than not-detection object in the image, are set. Brightness of each pixel of each image area is obtained, and it is determined whether the image area is the incompatible area or not on the basis of an evaluation value for determining whether or not an image area is an incompatible area estimated that image processing cannot be performed due to excess and deficiency of an exposure on the basis of the obtained brightness. In the control part 40, when it is determined that one of image areas is incompatible, the exposure control parameter of the next image acquisition is given to the on-vehicle camera 10 on the basis of the evaluation value to set the exposure of the on-vehicle camera 10.
