PROBLEM TO BE SOLVED: To provide an electronic endoscope apparatus capable of presenting a moving image which does not give a feeling of strangeness even when the temperature of the tip end of the endoscope insertion unit rises.SOLUTION: An electronic endoscope apparatus comprises: a light source control unit an imaging unit which comprises a light receiving unit including plural two-dimensionally arranged pixels and a drive control unit for driving the readout of imaging signals from the plural pixels and a control unit. The drive control unit drives the readout of imaging signals from the plural pixels in a period in which light emission stop control is performed in a frame period. The control unit, when the temperature of the tip end of the endoscope insertion unit exceeds a threshold value, lengthens the period in which the light emission stop control is performed with the length of the frame period fixed and decreases the speed of reading out imaging signals from the plural pixels, in a frame period following the frame period which includes the time when the temperature exceeding the threshold value was detected.COPYRIGHT: (C)2015,JPO&INPIT【課題】内視鏡挿入部の先端部の温度が上昇した場合でも、表示される動画として違和感のないものを提供することのできる電子内視鏡装置を提供する。【解決手段】電子内視鏡装置は、光源制御部と、二次元状に配置された複数の画素を含む受光部及び受光部から撮像信号を読み出す駆動を行う駆動制御部を含む撮像部と、制御部と、を備える。駆動制御部は、フレーム期間のうちの光出射停止制御が行われる期間において、複数の画素から撮像信号を読み出す駆動を行う。制御部は、内視鏡挿入部先端の温度が閾値を超えた場合に、フレーム期間の長さは固定のまま、当該閾値を超える温度が検出されたタイミングを含むフレーム期間より後のフレーム期間において、光出射停止制御が行われる期間を長くし、かつ、複数の画素からの撮像信号の読み出し速度を遅くする。【選択図】図2
