Abstract: An endoscope apparatus includes an optical system including a focus lens, a connector to which an interchangeable optical system is connected, an image sensor configured to output a captured image based on the optical system and the interchangeable optical system, and a processor including hardware. The processor performs a determination process of determining whether the interchangeable optical system is a known or unknown optical system, implements a first step amount determination process when the interchangeable optical system is determined to be a known optical system, and implements a second step amount determination process when the interchangeable optical system is determined to be an unknown optical system and controls the focus lens based on step amount information determined.

Abstract: An ultrasound probe includes: an ultrasound transducer provided on a distal end side of an outer tube; an actuator including a movable portion configured to perform a reciprocating motion; and a conversion mechanism. The conversion mechanism is arranged in the longitudinal direction of the outer tube in series with the actuator in the longitudinal direction, arranged in parallel to the ultrasound transducer in the longitudinal direction, and configured to convert the reciprocating motion of the movable portion to a swing motion of the ultrasound transducer. A working point in the mechanism is positioned off a center axis of the outer tube and a center axis of driving force of the reciprocating motion in the movable portion, and the center axis of the driving force of the reciprocating motion in the movable portion is displaced to the working point side by a predetermined distance relative to the center axis.
