Abstract
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 includes a receiving apparatus that has 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.
Claims12
A capsule endoscope system, comprising:
- a capsule endoscope that images image data of a subject, and transmits a radio signal that includes the image data of which a pixel defect is not corrected;
- and
- a receiving apparatus that receives the radio signal, and acquires the image data based on the radio signal received, and that includes a pixel defect corrector that detects and corrects a pixel defect of the image data.
A capsule endoscope system comprising:
- a capsule endoscope that is inserted into an interior of a subject, images image data of the interior of the subject, and transmits a radio signal that includes the image data;
- and
- a receiving apparatus that receives the radio signal and acquires the image data based on the radio signal received, wherein
- the capsule endoscope includes
- a parameter storage unit that stores specific information of the capsule endoscope, and
- a transmitter that transmits the radio signal that includes the image data and the specific information included in each line, wherein at least one portion of the specific information is included in each line, which serves as a unit of transmission at the time of transmission of the image data, and
- the receiving apparatus includes a control unit that determines whether the image data is effective or ineffective, based on the specific information included in the each line.
