You suppress the part light and darkness and the halation in the observation image, portray also the part shading of the observation target precisely and observe satisfactorily. Two dimensions make the aforementioned illumination light scan which is ejected from the aforementioned interposition section by vibrating light guide means (11) and the said light guide means which the interposition section (2) the light guide designate the illumination light which is begun shooting from the illuminant as the Tip at specified cycle, vis-a-vis the observation target the reflected light from the aforementioned observation target of scan means (12) and the aforementioned illumination light which absorbing light, the longitudinal direction of image pickup means (25) and the aforementioned interposition section which generate the picture signal on the basis of with scan position and the strength of the aforementioned reflected light due to aforementioned scan means and ejection direction to the aforementioned observation target of aforementioned illumination lightIn order to change the strength of the illumination light which is ejected from the aforementioned interposition section with according to the angle which is formed, the illuminant control means (21) which control the aforementioned illuminant and, the endoscope device which it has (1) is offered.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を行う。光源から射出された照明光を挿入部(2)先端に導光する導光手段(11)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(12)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(25)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(21)と、を備えた内視鏡装置(1)を提供する。
