「IMD2」を含む例文一覧(1)
- A threshold decision device 55 decides the threshold of the luminance value between a light source image and its background based on frequency distribution of the luminance value of background prepared based on the second probability density function, and an extraction device 56 extracts each picture element to the light source image from the imaging data IMD2 by binarizing the imaging data IMD2 by using the threshold.
閾値決定装置５５は、その第２確率密度関数に基づいて作成される背景の輝度値の頻度分布に基づいて、光源像とその背景との輝度値の閾値を決定し、抽出装置５６が、その閾値を用いて撮像データＩＭＤ２を二値化して撮像データＩＭＤ２の中から光源像に対する各画素を抽出する。 - 特許庁
