Abstract
An electronic endoscope system according to a first embodiment includes an electronic endoscope, a captured image processor, and an ultrasonic image processor. The electronic endoscope has, at a distal tip thereof, an image sensor, and an ultrasonic probe that repeatedly applies ultrasonic waves to sequentially obtain echo signals. The ultrasonic image processor has a noise detection unit that detects a noise component which is contained in a first echo signal among the echo signals and which is periodically generated at or above a preset threshold level, and a noise inhibition unit that generates a noise inhibition component which, by being added to a second echo signal outputted after the first echo signal, inhibits generation of the noise component in the second echo signal, and that adds the noise inhibition component to the second echo signal.
