Abstract

An endoscope system includes an image pickup device that is inserted into a subject and picks up an image inside the subject and a memory that records an intra-subject image acquired by the image pickup device and position information of the image pickup device in association with each other. The endoscope system includes an image generating section that applies, to the intra-subject image, when it is determined that a release signal is generated as a predetermined trigger signal, predetermined processing for distinguishably displaying the intra-subject image at a time when the release signal is generated and generates an image obtained by pasting the intra-subject image onto a model image of a predetermined organ.

First claim

What is claimed is:

1 . An endoscope system comprising:
an insertion section that is inserted into a subject; an objective optical window that is provided on a distal end side of the insertion section and receives light from the subject; an image pickup section that picks up an image inside the subject from the light made incident from the objective optical window; a position-information acquiring section that acquires position information of the objective optical window; a recording section that records an intra-subject image acquired by the image pickup section and the position information acquired by the position-information acquiring section in association with each other; an associating section that associates the position information recorded in the recording section with a model image of a predetermined organ in the subject; an image generating section that generates, as a pasted image, an image obtained by pasting the intra-subject image onto the model image of the predetermined organ associated by the associating section; a determining section that determines whether a predetermined trigger signal concerning the image pickup in the image pickup section is generated or a predetermined feature value of the intra-subject image acquired by the image pickup section satisfies a predetermined condition; and a control section that applies processing for pasting the intra-subject image, concerning which the predetermined trigger signal is determined as being generated or the predetermined feature value of which is determined as satisfying the predetermined condition by the determining section, closer to a front surface than other intra-subject images on the pasted image and applies image processing to the intra-subject image pasted onto the front surface to be distinguishable from the other intra-subject images.

2 . The endoscope system according to claim 1 , wherein the predetermined trigger signal is a release signal for recording the intra-subject image acquired by the image pickup section, an operation signal indicating predetermined operation for the insertion section of an endoscope in which the image pickup section is provided, or a changeover signal for an observation mode in picking up an image inside the subject.

3 . The endoscope system according to claim 1 , wherein the predetermined feature value is height of a convex portion on a subject surface in the intra-subject image, a color tone of the intra-subject image, or texture of the intra-subject image.

4 . The endoscope system according to claim 1 , wherein, when it is determined in the determining section that the predetermined trigger signal is not generated or the predetermined feature value does not satisfy the predetermined condition, the control section does not perform the image processing for making the intra-subject image to be distinguishable from the other intra-subject images on the intra-subject image pasted image.

5 . The endoscope system according to claim 1 , wherein the control section adds a frame image to the intra-subject image pasted onto the front surface.

6 . The endoscope system according to claim 1 , wherein the control section adds a predetermined mark to the intra-subject image pasted onto the front surface.

7 . The endoscope system according to claim 1 , wherein the control section differentiates a color tone of the intra-subject image pasted onto the front surface and a color tone of the other intra-subject images.

8 . The endoscope system according to claim 1 , wherein the control section paints out the other intra-subject images in a predetermined color.

9 . The endoscope system according to claim 1 , further comprising a spectral-estimation processing section that applies spectral estimation processing to the intra-subject image, wherein
the control section applies the predetermined processing to a plurality of models set according to operation modes of the spectral-estimation processing section and performs pasting of the intra-subject image.

10 . The endoscope system according to claim 1 , wherein the control section generates an enlarged image of the intra-subject image to which the image processing is applied.

11 . The endoscope system according to claim 1 , wherein
the intra-subject image is an image inside a bladder of the subject, and the model image is a model image of the bladder.

12 . The endoscope system according to claim 11 , wherein the model image is a 2D bladder development view.

13 . The endoscope system according to claim 1 , further comprising an instruction input section for an operator to input the predetermined trigger signal, wherein
when the predetermined trigger signal is input in the instruction input section, the control section applies the image processing for distinguishing the intra-subject image picked up by the image pickup section from other intra-subject images on the intra-subject image pasted image.

14 . The endoscope system according to claim 1 , wherein, when a plurality of intra-subject images, concerning which the predetermined trigger signal is determined as being generated or the predetermined feature value of which is determined as satisfying the predetermined condition by the determining section, are superimposed, the control section pastes an intra-subject image to which the image processing is applied later in time series onto an intra-subject image to which the image processing is applied earlier in time series.

15 . The endoscope system according to claim 1 , wherein, when a plurality of intra-subject images, concerning which the predetermined trigger signal is determined as being generated or the predetermined feature value of which is determined as satisfying the predetermined condition by the determining section, are superimposed, the control section applies the image processing to make the plurality of intra-subject images distinguishable from one another.

16 . An actuation method for an endoscope system including an image pickup section that picks up an image inside a subject from light made incident from an objective optical window provided on a distal end side of an insertion section inserted into the subject, a position-information acquiring section that acquires position information of the objective optical window, a recording section that records an intra-subject image acquired by the image pickup section and the position information acquired by the position-information acquiring section in association with each other, an associating section, an image generating section, a determining section, and a control section, the actuation method comprising:
the associating section associating the position information recorded in the recording section with a model image of a predetermined organ in the subject; the image generating section generating, as an intra-subject image pasted image, an image obtained by pasting the intra-subject image onto the model image of the predetermined organ associated by the associating section; the determining section determining whether a predetermined trigger signal concerning the image pickup in the image pickup section is generated or a predetermined feature value of the intra-subject image acquired by the image pickup section satisfies a predetermined condition; and the control section applying processing for pasting the intra-subject image, concerning which the predetermined trigger signal is determined as being generated or the predetermined feature value of which is determined as satisfying the predetermined condition by the determining section, closer to a front surface than o
