ENDOSCOPE SYSTEM AND METHOD FOR OPERATING ENDOSCOPE SYSTEM
First Claim
1. An endoscope system comprising:
- an insertion portion that is inserted into a subject;
an objective optical window that is provided on a distal end side of the insertion portion and receives light from the subject;
an image pickup section that picks up an image of an inside of the subject from the light entering from the objective optical window;
a position information acquiring section that acquires position information of the objective optical window;
an alignment section that aligns the position of the objective optical window acquired from the position information acquiring section with a reference position of a predetermined organ in the subject in a coordinate system of a three-dimensional model image based on an amount of change of subject internal image information inside the subject, predetermined operation input or the position information with respect to a preset reference plane; and
an image generating section that generates an image with the subject internal image pasted onto a two-dimensional model image of the predetermined organ obtained by two-dimensionally developing the three-dimensional model image in which the position of the objective optical window is associated with the position in the coordinate system by the alignment section.

Abstract
An endoscope system includes an insertion portion, an objective optical window, an image pickup device, a position/direction detection section that acquires position information of the objective optical window, and a memory that records the subject internal image acquired by the image pickup device in association with the position information of the objective optical window. The endoscope system aligns the position information of the objective optical window with a reference position of a predetermined organ in the subject in a coordinate system of a three-dimensional model image based on an amount of change or the like of the subject internal image information in the subject and generates an image with the subject internal image pasted onto the two-dimensional model image of the predetermined organ which is the three-dimensional model image two-dimensionally developed in which the position of the objective optical window is associated with the position in the coordinate system.

10. A method for operating an endoscope system comprising a position information acquiring section that acquires position information of an objective optical window of an insertion portion of an endoscope that receives light from a subject, an image pickup section that picks up an image of an inside of the subject from light inputted from the objective optical window, an alignment section and an image generating section, the method comprising:
-
the alignment section aligning the position of the objective optical window acquired from the position information acquiring section with a reference position of a predetermined organ in the subject in a coordinate system of a three-dimensional model image based on an amount of change of subject internal image information inside the subject, predetermined operation input or the position information with respect to a preset reference plane; and the image generating section associating the position of the objective optical window with the position in the coordinate system by the alignment section and generating an image with the subject internal image pasted onto a two-dimensional model image of the predetermined organ obtained by two-dimensionally developing the three-dimensional model image. - View Dependent Claims (11)
