1. An environment recognition device comprising:

  • a data retaining unit that retains association between a range of luminance and a specific object;

    a luminance obtaining unit that obtains a luminance of a target portion in a detection area of a luminance image;

    a white balance deriving unit that derives a white balance correction value, assuming white balance correction is performed on the obtained luminance;

    a corrected luminance deriving unit that subtracts a color correction value, based upon the white balance correction value and a color correction intensity indicating a degree of an influence of an environment light, from the obtained luminance so as to derive a corrected luminance; and

    a specific object provisional determining unit that provisionally determines a specific object corresponding to the target portion from the corrected luminance of the target portion on the basis of the association retained in the data retaining unit.
