Abstract

An endoscope system includes a determining section that determines whether or not an image pickup device is moving at a predetermined speed or higher based on position/direction information and determines, when the image pickup device is not moving at the predetermined speed or higher, that a subject internal image is an image that can be pasted onto a model image of a predetermined organ in a state where the position/direction information of an objective optical window and position/direction information in a coordinate system of the predetermined organ model image are associated with each other, and an image pasting section that reads the subject internal image determined to be the image that can be pasted from the memory and pastes the subject internal image onto the model image of the predetermined organ based on the position/direction information.

First claim

What is claimed is:

1. An endoscope system comprising:
an insertion portion that is inserted into a subject;
an objective optical window provided on a distal end side of the insertion portion to receive light from the subject;
an image sensor that picks up an image of an interior of the subject using the light incident on the objective optical window;
a memory that stores a predetermined organ model image of the subject; and
a controller configured to:
acquire position/direction information of the objective optical window;
record, in the memory, a subject internal image acquired by the image sensor and the acquired position/direction information in association with each other;
determine whether or not the image sensor is moving at a predetermined speed or higher based on the position/direction information and determine, when the image sensor is not moving at the predetermined speed or higher, that the subject internal image is an image that can be pasted onto a model image of the predetermined organ in a state where the position/direction information of the objective optical window and the position/direction information in a coordinate system of the predetermined organ model image are associated with each other; and
read the subject internal image determined to be the image that can be pasted from the memory and paste the subject internal image onto the model image of the predetermined organ based on the position/direction information.

2. The endoscope system according to claim 1 , further comprising a light source that radiates white light or narrow-band light having a predetermined wavelength band onto the subject in a manner switchable therebetween,
wherein the controller is further configured to set a plurality of model images of the predetermined organ and paste the subject internal image onto the model image based on the type of illuminating light.

3. The endoscope system according to claim 1 ,
wherein the subject internal image is an image of an interior of a bladder of the subject, and
the model image is a model image of the bladder.

4. The endoscope system according to claim 3 , wherein the model image is a 2D developed view of the bladder.

5. The endoscope system according to claim 1 , wherein the model image is a 3D image or a 2D image.
