To enable specification of an area where a person easily stays, such as a seat without storing many image data or the like.SOLUTION: For each of a plurality of divided areas set by dividing the detection area into a mesh shape, a superimposition count part 23 counts the number of times of superimposition in which detection areas, whose object is detected by the detection processing executed by the detection tally count, are overlapped on each other. By an area setting part 24, a divided area, in which the number of times of superimposition counted by the superimposition count part 23 is equal to or larger than a retention threshold, is set as a retention area in which the retention of the object may occur.SELECTED DRAWING: Figure 1 【課題】多くの画像データ等の蓄積をすることなく、座席といった人等が滞留し易いエリアを特定可能にする。【解決手段】重畳カウント部２３は、検知エリアをメッシュ状に分割して設定された複数の分割エリアそれぞれについて、検知集計回数実行された検知処理により対象物が検知された検知領域が重なる重畳回数をカウントする。エリア設定部２４は、重畳カウント部２３によってカウントされた重畳回数が滞留閾値以上である分割エリアを、対象物の滞留が発生する可能性がある滞留エリアとして設定する。【選択図】図１
