Abstract
A technique is proposed for enabling stable detection of an object even when the contrast of an image is lowered overall or partially. A preprocessing sectionis added to the upstream stage of an object detecting processing section, and provides an obtained corrected image (image obtained by subjecting an input image to contrast enhancement) as an input image for the object detecting processing section. This facilitates the detection of the object even when the contrast of the entire screen is lowered due to fog or rain. Furthermore, the object detecting processing sectiondetects the object by using not only the corrected image from the preprocessing sectionbut also correction characteristic informationcontaining image characteristics regarding the correction (contrast enhancement). This attempts to reduce an influence of noises enhanced by the contrast enhancement.
