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.

Abstract: A light source including LEDs for emitting violet, blue, green and red light is controlled, to change over a first emission mode for emitting light of all the four colors for broadband illumination, and a second emission mode for emitting green light for correction. A color image sensor having blue, green and red pixels is controlled, and outputs B1, G1 and R1 image signals by imaging in the first emission mode, and B2, G2 and R2 image signals by imaging in the second emission mode. The B2 image signal of the blue pixels in the second emission mode is subtracted from the B1 image signal of the blue pixels in the first emission mode. A high quality image is generated according to the B1 image signal after the subtraction. Thus, occurrence of poor quality of color rendering can be prevented.
