Abstract: A environment recognition device obtains luminances of a target portion existing in an area specifies a road surface luminance and a reference portion luminance; when the road surface luminance changes by a predetermined value or more, the reference portion luminance does not change by another predetermined value or more, and the changed road surface luminance is not a predetermined color, maintains a white balance correction value prior to the change until the road surface luminance returns to the predetermined color, and, in other cases, derives a white balance correction value to recognize the road surface luminance as the predetermined color; derives a corrected luminance by performing a white balance correction using the white balance correction value on the obtained luminance; and provisionally determines a object corresponding to the target portion from a corrected luminance of the target portion based on an association of a luminance range and the specific object.
