Zusammenfassung:	PROBLEM TO BE SOLVED: To improve object detection accuracy.SOLUTION: An integrated light-reception value is detected by changing two kinds of light emission intensity that are shown by a solid line and a dotted line. The correlation coefficient for every sampling time of the integrated light-reception value defined by the axis of abscissa in Fig.11 is calculated. The correlation coefficient is multiplied by the integrated light-reception value in the maximum light emission intensity. Then, the integrated light-reception value is corrected and on the basis of information on a time when the corrected integrated light-reception value comes to a peak position, the distance of an object is made to be detected. This invention, for example, can be applied to a laser radar device for a vehicle. 【課題】物体の検出精度を向上させる。【解決手段】実線と点線で示されるような２種類の発光強度を変化させて積算受光値を検出し、図１１の横軸で定義される積算受光値のサンプリング時刻毎の相関係数を算出し、最大発光強度における積算受光値に相関係数を乗じることにより、積算受光値を補正し、補正した積算受光値のピーク位置となる時刻の情報に基づいて物体の距離を検出するようにする。本発明は、例えば、車両用のレーザレーダ装置に適用できる。【選択図】図１１
