Abstract: An endoscopic system includes: an endoscope acquiring an image of an inside of a subject; and a processing device performing image processing on the acquired image. The endoscope includes: an imaging unit outputting the image of the inside of the subject as an electrical signal; and an optical transmission unit converting the electrical signal into an optical signal and transmitting the optical signal to the processing device via an optical fiber. The processing device includes: an optical reception unit receiving the optical signal transmitted from the optical transmission unit and converts the received optical signal into an electrical signal; a curvature-detecting unit detecting a curvature of the optical fiber, and a control unit controlling at least one of characteristics of the electrical signal output from the imaging unit and characteristics of the electrical signal output from the optical transmission unit based on the detection result of the curvature-detecting unit.

Abstract: An ultrasound unit includes: ultrasound elements each including a plurality of ultrasound cells formed on a substrate including a semiconductor, the plurality of ultrasound cells each including an upper electrode having a ground potential and a lower electrode to which a drive signal is applied, the upper electrode and the lower electrode being arranged facing each other via a cavity and thereby forming a first capacitor; a package member in which the plurality of ultrasound elements are disposed, the package member having a ground potential; and an insulation member disposed between the package member and each of the ultrasound elements. A second capacitor is formed as a result of the insulation member serving as a gap, and a capacity of a third capacitor serially connected to the second capacitor is smaller than a capacity of the second capacitor.
