Abstract: An imaging unit provided at a tip portion of an endoscope includes: an imaging element configured to receive light and perform photoelectric conversion on the light to generate an electrical signal; an oscillator configured to generate a clock signal for driving the imaging element; a photoelectric element configured to convert the electrical signal generated by the imaging element into an optical signal and to output the optical signal to outside; a regulator configured to convert electric power input from the outside into electric power depending on each of the imaging element, the oscillator, and the photoelectric element, and to supply the converted electric power thereto. The imaging element is spaced farther than the oscillator and the photoelectric element from the regulator.

Abstract: An endoscope system includes: an image sensor, a first photoelectric sensor configured to convert an imaging signal and test data output from the image sensor into an optical signal and output the optical signal, optical fibers configured to transmit the optical signal output from the first photoelectric sensor, and an information processing device. The information processing device includes a second photoelectric sensor configured to receive the optical signal transmitted through the optical fibers, and is configured to: measure a current value corresponding to a receiving sensitivity of the test data converted into an electric signal by the second photoelectric sensor; measure a bit error rate of the test data; determine a transmission level of the test data based on the current value and the bit error rate; and assume reasons for a decrease in the transmission level and cause the transmission level to recover based on the transmission level.
