Abstract
Description
このような内視鏡装置において、観察対象に照射される照明光の強度が1つの画像をなすフレーム内で常に一定である場合には、取得した画像中に暗部やハレーション等が生じやすい。特に、観察対象が消化管等の管腔状構造である場合には画像中心が極端に暗くなる一方、周辺部分が過度に明るくなり、ハレーションが生じやすい。
このため特許文献1には、取得済みのフレーム像の明暗情報に基づいて、照明光の走査位置に応じた任意のエリアの照明光量を調整する内視鏡装置が記載されている。
本発明の一態様は、光源から射出された照明光を挿入部先端に導光する導光手段と、該導光手段を所定周期で振動させることにより、前記挿入部から射出する前記照明光を観察対象に対して二次元走査させる走査手段と、前記照明光の前記観察対象からの戻り光を受光して、前記走査手段による走査位置と前記戻り光の強度とに基づいて画像信号を生成する撮像手段と、前記挿入部の長手方向と前記照明光の前記観察対象への射出方向とのなす角度に応じて前記挿入部から射出する照明光の強度を変化させるように前記光源を制御する光源制御手段と、を備えた内視鏡装置である。
そこで、光源制御手段により挿入部の長手方向と照明光の観察対象への射出方向とのなす角度に応じて挿入部から射出する照明光の強度を変化させるように光源を制御することで、走査期間における配光斑を抑制し、観察画像における部分的な明暗やハレーションを抑制し、観察対象の部分的な陰影をも的確に描出して良好な観察画像を取得することができる。
このようにすることで、単位走査期間において、挿入部から射出する照明光の射出角度が小さく、観察画像の中心となる像に対しては相対的に照明光の強度を大きくし、挿入部から射出する照明光の射出角度が大きい挿入部先端周辺部分に対しては相対的に照明光の強度を小さくすることで、取得する観察画像における部分的な明暗差やハレーションを抑制することができる。
このようにすることで、取得する観察画像における明暗差やハレーションを抑制することができる。

このようにすることで、取得する観察画像における明暗差やハレーションを抑制することができる。
このようにすることで、例えば、撮像手段の特性や撮像環境により観察画像全体が暗い場合乃至は明るい場合において、観察画像における部分的な明暗差やハレーションを抑制しながら、観察画像全体の明るさも調節することができ、良好な観察画像を取得することができる。

上記した実施形態において、レンズ13には特段の光学特性がなく、例えばカバーガラス等を適用することができる。しかしながら、レンズ13に例えば、ARコーティング処理が施されたものや、広角レンズ等が適用される場合もあり、このような場合には、光源制御部21による光源20R,20G,20Bの制御を以下のようにする必要がある。
そこで、このような場合には、挿入部から射出する照明光の射出角度θが大きくなるほど光源20R,20G,20Bからライトガイドファイバ11へ供給する照明光の強度が大きくなるように光源を制御する。
