Charging device 10 charges nickel-hydrogen batteries 58, while adjusting the current value so that the temperature follows the target temperature rise pattern. Therefore, nickel-hydrogen batteries that demonstrate a large temperature increase can be charged within a short time so that a high temperature is not attained. Furthermore, when lithium ion batteries 58 are charged, the current value is controlled so that the voltage follows the target voltage rise pattern. Therefore, lithium ion batteries can be charged at a potential no higher than the preset level.

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.
