PROBLEM TO BE SOLVED: To precisely specify the shadow region of a moving object.SOLUTION: A moving object detection device 100 compares luminance values amongst a plurality of image frames for extracting a first region in which differences are present. The moving body detection device 100 divides the first region into a plurality of second regions. The moving body detection device 100 determines, based on the ratio of luminance values amongst the image frames corresponding to each of the second regions, such a plurality of second regions in which the ratio of luminance values becomes a reciprocal relationship, as the shadow region.SELECTED DRAWING: Figure 4
【課題】移動体の影の領域を正確に特定する。【解決手段】移動体検出装置100は、複数の画像フレーム間の輝度値の比較を行うことで、差分の発生している第1領域を抽出する。移動体検出装置100は、第1領域を複数の第2領域に分割する。移動体検出装置100は、各第2領域に対応する画像フレーム間の輝度値の比率を基にして、輝度値の比率が逆数の関係となる複数の第2領域を、影の領域として判定する。【選択図】図4
