Abstract

An image selection support device supports the selection of a still image based on captured image data obtained by an endoscope. By using a first still image acquired based on the captured image data at a time when an operator of the endoscope performs an acquisition operation of the still image, and one or more second still images acquired from the captured image data at a time different from the time when the acquisition operation is performed, the image selection support device extracts a third still image having an imaging time point that satisfies a predetermined condition with an imaging time point of the first still image from among the second still images, and associates the first still image with the third still image.

First claim

What is claimed is:

1. An image selection support device that supports selection of a still image, the device comprising:
an endoscope that captures image data;
a processor; and
a memory,
wherein
the memory records a first still image acquired based on the captured image data at a time when an operator of the endoscope performs an acquisition operation of a still image, and one or more second still images acquired from the captured image data at a time different from the time when the acquisition operation is performed so that the first still image does not include an image identical to the second still image,
the second still image is a still image acquired from the captured image data in response to a detection of a specific finding based on an analysis of the captured image data,
the analysis includes a calculation of a correct diagnosis rate indicating a probability that a correct diagnosis is performed based on the second still image, based on the captured image data, and
the second still image is a still image acquired from the captured image data in a case in which the captured image data of which the calculated correct diagnosis rate is equal to or more than a certain value is continuously obtained by a certain number or more, and

the processor is configured to
extract a third still image from among the one or more second still images, an imaging time point of the third still image and an imaging time point of the first still image satisfying a predetermined condition,
associate the first still image with the third still image,
display the first still image and the third still image on a display in association with each other, and
select, as a selected still image, a still image on which a selection operation by a user is performed, from the first still image and the third still image displayed on the display in association with each other.

2. The image selection support device according to claim 1 ,
wherein the processor displays the first still image and the third still image on the display in a comparable manner.

3. The image selection support device according to claim 1 ,
wherein the processor simultaneously displays the first still image and the third still image in different regions of the display.

4. The image selection support device according to claim 1 ,
wherein the processor displays the first still image and the third still image on the display in a switching manner based on time.

5. The image selection support device according to claim 1 ,
wherein the processor
extracts a fourth still image from among the one or more second still images, an imaging time point of the fourth still image and the imaging time point of the first still image not satisfying the predetermined condition,
displays the fourth still image on the display, and
selects, as a selected still image, a still image on which a selection operation by a user is performed, from the fourth still image.

6. The image selection support device according to claim 1 ,
wherein the selected still image is a candidate image for an image to be inserted into a report of an examination by the endoscope.

7. The image selection support device according to claim 1 ,
wherein the analysis is performed by an analysis device that receives the captured image data from the endoscope, and
the second still image is a still image acquired by the analysis device from the captured image data.

8. The image selection support device according to claim 1 ,
wherein the second still image includes a still image acquired from the captured image data obtained by the endoscope in a state in which an emission spectrum of illumination light used in imaging by the endoscope is switched in response to the detection of the specific finding based on the analysis of the captured image data.

9. The image selection support device according to claim 8 ,
wherein the second still image includes a still image acquired from the captured image data in which the specific finding is detected, and a still image acquired from the captured image data obtained by the endoscope in a state in which the emission spectrum of the illumination light used in the imaging by the endoscope is switched in response to the detection of the specific finding.

10. The image selection support device according to claim 1 ,
wherein the processor extracts the third still image from among the one or more second still images such that a difference between an imaging time point of the third still image and an imaging time point of the first still image is equal to or less than a prescribed value.

11. The image selection support device according to claim 1 ,
wherein, in a case in which a plurality of first still images are acquired, the processor extracts the third still image for a first still image on which a selection operation by a user is performed, from among the plurality of first still images acquired.

12. An image selection support device that supports selection of a still image, the device comprising:
an endoscope that captures image data;
a processor; and
a memory,
wherein the memory records a first still image acquired based on the captured image data at a time when an operator of the endoscope performs an acquisition operation of a still image, and one or more second still images acquired from the captured image data at a time different from the time when the acquisition operation is performed so that the first still image does not include an image identical to the second still image, and
the processor is configured to
extract a third still image from among the one or more second still images, an imaging time point of the third still image and an imaging time point of the first still image satisfying a predetermined condition,
associate the first still image with the third still image,
display the first still image and the third still image on a display in association with each other, and
select, as a selected still image, a still image on which a selection operation by a user is performed, from the first still image and the third still image displayed on the display in association with each other,

wherein the second still image is a still image acquired from the captured image data in response to a detection of a specific finding based on an analysis of the captured image data,
the analysis includes a calculation of a correct diagnosis rate indicating a probability that a correct diagnosis is performed based on the second still image, based on the captured image data, and
the second still image is a still image acquired from the captured image data in a case in which the captured image data of which the calculated correct diagnosis rate is equal to or more than a certain value is continuously obtained by six frames or more.
