PROBLEM TO BE SOLVED: To solve a problem in which the time required for analysis becomes long and another vehicle cannot be quickly detected since the data number used in determination of a peripheral environment is enormous.SOLUTION: A specific color region detection unit 211 extracts as a specific color region a region constituted of the red color being the color of a taillight of a preceding vehicle, the red color, yellow color and green color being the display colors of a traffic light from a frame image acquired by a camera 121. A processing object range calculation unit 212 acquires the specific color region from the specific color region detection unit 211 and calculates a range including the on-coming lane and the like to be used in processing of a vehicle region detection unit 213 on the basis of the specific color region. The vehicle region detection unit 213 acquires the range including the on-coming lane and the like from the processing object range calculation unit 212 and detects the vehicle region on the basis of a headlight of another vehicle from the range.SELECTED DRAWING: Figure 2
【課題】周辺環境の判定に用いられるデータ数が莫大であるため、解析に要する時間が長くなり、他車両を迅速に検出できないという問題があった。【解決手段】特定色領域検出部２１１は、カメラ１２１が取得したフレーム画像から、先行車のテールライトの色である赤色、信号機の表示色である赤色、黄色、緑色で構成される領域を特定色領域として抽出する。処理対象範囲算出部２１２は、特定色領域検出部２１１から特定色領域を取得し、特定色領域に基づいて、車両領域検出部２１３の処理に用いる例えば対向車線を含む範囲などを算出する。車両領域検出部２１３は、処理対象範囲算出部２１２から対向車線を含む範囲などを取得し、この範囲から、他車両のヘッドライトを基に車両領域を検出する。【選択図】 図２
