Abstract: An endoscope system computes a distal end position of the endoscope or a position of the desired imaging target. An image taken of the desired imaging target is recorded. A position of the desired imaging target is computed and recorded. A current image taken by the imaging unit is compared with the image of the desired imaging target already recorded. A first driving amount for driving the field-of-view adjustment mechanism is computed such that the desired imaging target is positioned on an axis of sighting of the imaging unit. A second driving amount for driving the field-of-view adjustment mechanism is computed in such a way as to include a center of the image of the desired imaging target. The field-of-view adjustment mechanism is driven from either one of the first driving amount or the second driving amount.

Abstract: The technology disclosed herein is directed to an endoscope system. The endoscope system includes an endoscope, a sensor; and a controller. The controller is configured to control the endoscope. The controller includes one or more processors. The one or more processors is configured (i) to extract first feature points from a first image captured by the endoscope, (ii) to extract second feature points from a second image captured by the endoscope after acquisition of the first image, (iii) to estimate a first result of position and orientation of the endoscope based on the first feature points and the second feature points, (iv) to calculate a first estimation accuracy based on the first result. When the first estimation accuracy is greater than a predetermined value, the one or more processors utilizes the first result as position and orientation of the endoscope.

Abstract: An object of the invention is to provide for automatic angular adjustment of an end effector thereby improving on the operability of a medical instrument. The medical system of the invention comprises a medical instrument including a driver for driving adjustment of the angle of the end effector relative to a shaft, a trocar having an insertion opening through which the medical instrument is inserted, a sensor that produces a sensor signal including at least an angle of a shaft in a reference coordinate system, and a driver for enabling follow-up control processing for driving the driver based on a sensor signal produced out of the sensor such that the angle of the end effector follows a follow-up criterion in a reference coordinate system.

Abstract: The technology disclosed herein is directed to a medical manipulator system having a medical device. The medical device such as endoscope or other surgical instrument includes an elongated insertion portion. A holder assembly includes an articulated arm carrying the medical device that is attached thereto and is actuated following movement of the medical device and holds the medical device in a stationary state at a desired position. A position/attitude detection unit detects positions and attitudes of the elongated insertion portion in plurality states into which the medical device is caused to swing about a constraint point. A constraint point estimation unit estimates a position of the constraint point based on the positions and attitudes of the insertion portion as detected by the position/attitude detection unit.

Abstract: A medical-system control method including a switching-instruction step in which an instruction for switching between two different control states of the bendable section provided at a distal end of the insertion section is received; an angle-difference calculation step in which the difference between the current angle of the bendable section at the time when the instruction is received and the final target angle of the bendable section in the control state after being switched is calculated; a target calculation step in which, when the calculated difference exceeds a predetermined threshold, a minute angle, smaller than the threshold, is added to the current angle to calculate the target angle, and, when the difference is less than or equal to the threshold, the difference is added to the current angle to calculate the target angle; and a driving step in which the bendable section is driven to the calculated target angle.

Abstract: A method of measuring distance by an endoscope includes a step of imaging and a step of measuring distance. the step of imaging includes a step of producing out an image taken by an imaging unit. The step of measuring distance includes a step of moving the axis of sighting of the imaging unit and a step of computing a distance to a subject of interest on the basis of a first image taken before the step of moving, a second image taken during the step of moving and the amount of distance-measurement control.
