Abstract
Description
図1から図9は本発明の実施形態1を示したものであり、図1は通常光および特殊光による観察が可能な内視鏡システム1の構成例を示す図である。
これに対して、各係数kr,kg,kbの値を正または0の範囲でどのように調整したとしても、特殊光のスペクトルX(λ)に一致させることができないとき、Xを特殊光と呼ぶものとする。なお、通常光としてバイオレットV(λ)をさらに含める場合でも、係数kvを用いた「+kv×V(λ)」を上述した線形結合に追加すればよく、同様の定義を用いることができる。
τ2max=c×τ1max
を与える係数cが挙げられる。
P1/P2=P1max/P2max
が維持されるように、電流値I1および電流値I2を制御するようになっている。
τ1/τ2=τ1max/τ2max
が維持されるように、PWMデューティD1,D2を変化させるようになっている。ここに、本実施形態においては、1枚の画像(例えば1フレームの画像)の露光期間における光源を発光させるための電流パルスが1つであることを想定しているために、PWMデューティD1,D2を変化させる制御は、発光時間τ1,τ2を変化させる制御と同等である(電流パルスが複数(n個)であるときは、PWMデューティD1,D2を変化させる制御は、発光時間τ1×n,τ2×nを変化させる制御となる)。
図10から図12は本発明の実施形態2を示したものであり、図10は通常光および特殊光による観察が可能な内視鏡システムの構成例を示す図である。
