Abstract
Description
図1から図7は本発明の実施形態1を示したものであり、図1は走査型内視鏡装置の構成例を示す図である。
f=α×f1+f2
ここにαは、検出信号f1の信号強度を検出信号f2の信号強度に合わせるための補正係数である。
f=α×(f1−<f1>)+f2
検出信号f1から平均値<f1>を減算すれば、検出信号f1に含まれる戻り光成分(図5に示すピークf1a以外のなだらかな信号成分)が概略除去され、ほぼピークf1aのみが残ることになる。従って、この数式2に基づき画像信号をfを生成すれば、第2光検出部12の検出結果が画像全体に渡ってレベルアップするのを抑制することができ、画像のコントラストを向上することができる。しかも、(f1−<f1>)の演算により抽出されるピークf1aには戻り光成分が概略含まれていないために、補正係数αを乗算することで、検出信号f2の強度に対する、外部要因光21aに起因するピークf1aの強度の比をより正確に反映することが可能となる。
図8は本発明の実施形態2を示したものであり、走査型内視鏡装置の構成例を示す図である。この実施形態2において、上述の実施形態1と同様である部分については同一の符号を付すなどして説明を適宜省略し、主として異なる点についてのみ説明する。
