Abstract: An electronic endoscopic device includes a light source, an endoscopic scope including an imaging unit provided at a tip end, a temperature detecting unit that detects a temperature of the tip end, and a light source control unit that performs a light emission control and a light emission stop control in a frame period. The imaging unit includes a plurality of pixels and a driving unit, and the electronic endoscopic device further includes a control unit in which, when a temperature detected by the temperature detecting unit exceeds a threshold value, the control unit performs a control such that, in a frame period following a first frame period, a period in which the light emission stop control is performed is set to be longer, and a read-out speed of the imaging signal is set to be slower.
