An electronic endoscope apparatus includes: a CCD a temperature sensor that detects a temperature of a distal end portion a correlated double sampling section provided in a body portion, the correlated double sampling section extracting a signal component from an image signal outputted from the CCD a timing generator that generates a sample-and-hold signal for making the correlated double sampling section operate and a drive pulse signal for driving the CCD and a CPU that adjusts a timing of the sample-and-hold signal or the drive pulse signal generated by the timing generator, based on the temperature detected by the temperature sensor.
