Abstract

　撮像対象の手前にある移動物体によるノイズを比較的簡単な方法で効果的に除去することを可能とする。 　移動物体ノイズ除去の手順は、まずカメラによって所定のサンプリング間隔Δｔごとに撮像が行われ、撮像の時系列に関連付けて記憶される（Ｓ１０，Ｓ１２）。つぎに、現在に撮像された画像フレームデータと現在より前の時刻における画像フレームデータについて、対応する各画素の輝度値が比較される（Ｓ１４，Ｓ１６，Ｓ１８）。そして、各画素について、輝度値の高い方がノイズとして除去され、輝度値の低い方が残される（Ｓ２０）。各画素において残された輝度値で画像フレームの各画素の輝度値が更新され出力される（Ｓ２２，Ｓ２４）。また、全部のデータ数に対する除去された輝度値のデータ数の割合から移動物体頻度が算出され、出力される（Ｓ２６，Ｓ２８）。
