PROBLEM TO BE SOLVED: To enable the proper specification of a tail lamp.SOLUTION: In a vehicle outside environment recognition device, a computer functions as a three-dimensional position derivation part for deriving a depth distance of a block in a first image of a prescribed exposure time, and a preceding vehicle extraction part for extracting a tail lamp of the preceding vehicle on the basis of the luminance and the depth distance of the block in the first image. If the depth distance of the block is less than a prescribed distance threshold, the preceding vehicle extraction part extracts the tail lamp of the preceding vehicle on the basis of the luminance and the depth distance of the block in a second image having a shorter exposure time than the first image does.SELECTED DRAWING: Figure 9

    【課題】テールランプを適切に特定可能となる。【解決手段】車外環境認識装置では、コンピュータが、所定の露光時間の第1画像におけるブロックの奥行き距離を導出する3次元位置導出部と、第1画像におけるブロックの輝度と奥行き距離とに基づいて先行車両のテールランプを抽出する先行車両抽出部、として機能し、先行車両抽出部は、ブロックの奥行き距離が所定の距離閾値未満であれば、第1画像より露光時間の短い第2画像におけるブロックの輝度と奥行き距離とに基づいて先行車両のテールランプを抽出する。【選択図】図9
