Abstract: A method of controlling the medical master/slave system comprising a bendable master apparatus operated by an operator and a slave apparatus inserted through the body. The control method includes an ordinary actuation mode (Step S101) in which, based on a bending state of the master apparatus, the slave apparatus is actuated in such a way as to become similar in operation to the master apparatus, a reversal actuation mode (Step S105) in which, based on a bending state of the master apparatus, the slave apparatus is actuated in such a way as to be reversed relative to the operation of the master apparatus, and a transition mode (Step S103, S104, S107, S108) for transition between the ordinary actuation mode and the reversal actuation mode.

Abstract: Provided is an operation input device including a base member; a grip that is gripped by an operator and that is moved relative to the base member; a coupling portion that couples the grip to the base portion in a pivotable manner; and a scaling-ratio changing mechanism that changes an amount by which the grip is moved with respect to a pivoting angle of the coupling portion, and an object thereof is to enable switching operation between a coarse movement and a fine movement by using the same operation.

Abstract: A medical device including a long main body having a distal end portion; two or more movable portions arranged at the main body or in a vicinity of the distal end portion; a single input interface part operated by an operator; and a control part switching and controlling the respective movable portions in accordance with an operation amount input to the input interface part.

Abstract: Eye fatigue in an observer is reduced in the case in which observation is performed by performing visual comparison between an imaging subject and an auxiliary indication superimposed on the imaging subject in a three-dimensional image. Provided is an image-processing device including a display portion that displays a three-dimensional image reproduced from two parallax images of an imaging subject; attention-point detecting portions that detect an attention point of the observer observing the three-dimensional image; a parallax calculating portion that calculates parallax between the two parallax images at the detected attention point; an auxiliary-indication creating portion that creates an auxiliary indication to which the same parallax as the parallax calculated by the parallax calculating portion is assigned, that superimposes the created auxiliary indication on the three-dimensional image, and that displays the superimposed image on the display portion.
