Patent ID: 8861787

Claim:
An environment recognition device comprising: a data retaining unit that retains association between ranges of luminance value and specific objects; a luminance obtaining unit that obtains a luminance value of a target portion in a detection area of a luminance image; a white balance obtaining unit that obtains a white balance correction value; a corrected luminance obtaining unit that subtracts a color correction value, which is obtained 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 value so as to obtain a corrected luminance value; and a first specific object determining unit that determines a specific object corresponding to the target portion based on the corrected luminance value of the target portion by using the association retained in the data retaining unit, wherein the color correction intensity is calculated based upon an intensity of the environment light and a transmittance of a transmission body crossing an imaging axis.
