To provide a capsule endoscope system capable of easily detecting or correcting a communication error, without increasing power consumption of the capsule endoscope. The capsule endoscope system according to the present invention comprises a receiving apparatus that includes a pixel defect corrector. The receiving apparatus receives a radio signal that includes image data imaged by a capsule endoscope inserted into an internal portion of a subject, and acquires the image data based on the received radio signal. The pixel defect corrector detects a pixel defect of the image data based on a pixel value of each pixel that configures the acquired image data, and corrects the detected pixel defect.
