PROBLEM TO BE SOLVED: To provide a scanning endoscope apparatus that can easily determine whether or not an image comprises distortion and can generate a distortion-corrected image.SOLUTION: A scanning endoscope apparatus is characterized as follows: a predetermined number of markers 53 having high reflectivity is arranged on linear lines Lh, Lv on a marker plate 52 a detection signal detected when pulse emission is made in timing where a driving signal for performing a spiral scan by a scanning endoscope 2 crosses the linear lines Lh, Lv is extracted a distortion determination circuit 48 determines whether or not a distortion is large according to a value of a counted value of the detection signal having a brightness value not less than a threshold value counted by a counter circuit 47 a marker plate 52 is moved when the distortion is large, and a detection signal for correction having a brightness value not less than a threshold value is acquired and an irradiation position before the correction stored in a memory 43 is corrected according to a movement amount when acquiring the detection signal for correction.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】画像が歪みを含むか否かを簡単に判定でき、歪み補正した画像を生成することができる走査型内視鏡装置を提供する。【解決手段】マーカ板52上の直線ラインLh,Lv上に反射率が高い所定数のマーカ53を配置し、走査型内視鏡2により渦巻き状の走査を行う駆動信号が直線ラインLh,Lvをクロスするタイミングでパルス発光させた場合に検出される検出信号を抽出し、計数回路47により計数した閾値以上の輝度値を有する検出信号の計数値の値に応じて、歪み判定回路48は歪みが大きいか否かを判定し、歪みが大きい場合にはマーカ板52を移動して、閾値以上の輝度値を有する補正用の検出信号を取得し、補正用の検出信号を取得した場合の移動量に応じてメモリ43に格納した補正前の照射位置を補正する。【選択図】図4
