Abstract: To accurately predict a sensor value even in the case where external force is received. A control apparatus according to the present disclosure includes: a prediction section (260) configured to, in an actuator including a torque sensor that detects torque generated at a driving shaft, and an encoder that detects a rotational angle of the driving shaft, predict a detection value of the encoder on a basis of a detection value of the torque sensor, or predict the detection value of the torque sensor on a basis of the detection value of the encoder; and a trouble determination section (266) configured to compare a prediction value predicted by the prediction section with an actually measured value of the torque sensor or the encoder to perform trouble determination on the torque sensor or the encoder.

Abstract: [Overview] [Problem to be Solved] To make it possible to appropriately rotate an endoscope.
[Solution] There is provided an endoscope including: a main body including a coupler to which a cable is attached; a tubular section having a tubular form; a reflector having a reflection surface that reflects light introduced from the coupler to inside of the main body and introduces the light to inside of the tubular section; a first optical system that transmits the light introduced by the reflector to the inside of the tubular section to a front-end portion of the tubular section and irradiates a subject with the light from the front-end portion; and a second optical system that transmits reflected light of the subject from the front-end portion of the tubular section to the main body side. The coupler is provided to be rotatable in the main body around a central axis of the tubular section with respect to another portion. The cable being coupled to a light source. The tubular section is fixed to the main body and extends from the main body.

Abstract: [Object] To always have an observation target object within the region of a picked up image in the case where an oblique-viewing endoscope is inserted into the human body for operation.[Solution] A medical supporting arm according to the present disclosure includes: a supporting arm configured to support an oblique-viewing endoscope; and a calculation unit configured to calculate a rotation angle of the oblique-viewing endoscope around an axis in a longitudinal direction, and an insertion amount of the oblique-viewing endoscope into a human body on the basis of a first expression that defines coordinates of a subject in a coordinate system in which an insertion opening allowing the oblique-viewing endo scope to be inserted into the human body serves as an origin, and a second expression that defines the coordinates of the subject positioned in an optical axis direction of an objective lens disposed at a distal end of the oblique-viewing endoscope in a coordinate system in which the distal end of the oblique-viewing endoscope serves as an origin.

Abstract: Provided is an image processing device including: an image processing unit that generates image data for output from a captured image of an inside of a body cavity of a patient photographed by an endoscope. The image processing unit generates the image data in a manner that, when a lens barrel of the endoscope is moved in an optical axis direction of an objective lens during photographing, a display range in the captured image that is a range expressed in a display image displayed on a display device does not change, during the movement and after the movement, from a display range before the movement.
