Abstract: An electronic endoscope system is composed of an electronic endoscope, a light source apparatus, and a temperature converter. The electronic endoscope has a CMOS sensor in a distal portion of an insert section to be inserted into a patient's body cavity. Illumination light from the light source apparatus is applied to the body cavity through the distal portion. The temperature converter obtains an average pixel value of an optical black (OB) region out of an imaging signal from the CMOS sensor, and converts the average OB pixel value into a temperature of the CMOS sensor on a frame-by-frame basis with the use of data in a temperature conversion table. The table represents a relationship between the average OB pixel value and the temperature of the CMOS sensor. Light quantity of the illumination light is adjusted in accordance with the temperature of the CMOS sensor to prevent deterioration of image quality.

Abstract: The invention provides an endoscope connector capable of stably performing image communication, an endoscope including the endoscope connector and endoscope system. An endoscope connector is provided in an endoscope having an imaging unit at a distal end of an insertion portion, connected with an endoscope processor device, and provided with an image signal transmitting unit transmitting an image signal with respect to the endoscope processor device via optical communication. The image signal transmitting unit is arranged in an image signal transmitting connector connected with a processor device connector. The image signal transmitting connector includes a glass member provided at the tip end through which the image signal passes and a guide member formed on a circumference of the glass member. The guide member has grooves thereon radially extending from the glass member.
