摘要： A controller controls a movement of an endoscope to cause the endoscope to follow a surgical instrument. The controller includes a processor. The processor acquires position information including the position of the surgical instrument, acquires scene information associated with a procedure scene to be observed through the endoscope, determines an offset parameter, which determines the position of the target point with respect to a predetermined fiducial point in the field of view of the endoscope, of a target point on the basis of the scene information, sets the position of the target point with respect to the fiducial point on the basis of the offset parameter, and causes the endoscope to follow the surgical instrument such that the surgical instrument is disposed at the target point, by controlling a movement of the endoscope on the basis of the position of the target point and the position of the surgical instrument.

摘要： An endoscope system includes: an endoscope configured to acquire an image; and at least one processor including hardware. The at least one processor is configured to: acquire a distance from a treatment tool to target, acquire an operation state of the treatment tool, and determine a necessity for zooming in and zooming out on the basis of at least one of the distance and the operation state.

摘要： An endoscope system includes an endoscope, a moving device that moves the endoscope, a storage unit, and a processor. The storage unit stores first position information and first rotation angle information, which defines a rotation angle of an endoscope image of a first region, on the first region in a subject and second position information and second rotation angle information, which defines a rotation angle of an endoscope image of a second region, on the second region in the subject. The processor calculates third rotation angle information on a third region in the subject based on the first and second position information, the first and second rotation angle information, and third position information on the third region. If the third region includes the current imaging region, the processor rotates the endoscope image based on the third rotation angle information and outputs the rotated endoscope image to the display device.
