Abstract

An endoscope system includes: an endoscope including a side-viewing observation unit that includes a field of view in a lateral direction of an insertion part to be inserted into an object to be observed and a second protruding portion that protrudes from the insertion part and forms a blind spot in the field of view of the side-viewing observation unit; an image acquisition unit that acquires a side-viewing observation image by using the side-viewing observation unit; a monitor that displays the side-viewing observation image; and a display control section that allows at least a part of the blind spot of the side-viewing observation image in which the second protruding portion is shown up not to be displayed, and displays the side-viewing observation image on the monitor.

First claim

What is claimed is:

1 . An endoscope system comprising:
an endoscope including a side-viewing observation unit that includes a field of view in a lateral direction of an insertion part to be inserted into an object to be observed and a protruding portion that protrudes from the insertion part and forms a blind spot in the field of view of the side-viewing observation unit; an image acquisition unit that acquires a side-viewing observation image by using the side-viewing observation unit; a display unit that displays the side-viewing observation image; and a display control section that allows at least a part of the blind spot of the side-viewing observation image in which the protruding portion is shown up not to be displayed, and displays the side-viewing observation image on the display unit.

2 . The endoscope system according to claim 1 ,
wherein the display control section allows at least a part of the blind spot not to be displayed by offsetting a display position of the side-viewing observation image with respect to a display region on the display unit.

3 . The endoscope system according to claim 1 ,
wherein the display control section allows at least a part of the blind spot not to be displayed by enlarging the side-viewing observation image with respect to the display region on the display unit.

4 . The endoscope system according to claim 2 ,
wherein the display control section allows at least a part of the blind spot not to be displayed by enlarging the side-viewing observation image with respect to the display region on the display unit.

5 . The endoscope system according to claim 1 ,
wherein the display control section includes a blind spot-non-display mode as a display mode for the side-viewing observation image, and allows at least a part of the blind spot not to be displayed and displays the side-viewing observation image on the display unit in a case in which the display mode is set to the blind spot-non-display mode.

6 . The endoscope system according to claim 2 ,
wherein the display control section includes a blind spot-non-display mode as a display mode for the side-viewing observation image, and allows at least a part of the blind spot not to be displayed and displays the side-viewing observation image on the display unit in a case in which the display mode is set to the blind spot-non-display mode.

7 . The endoscope system according to claim 3 ,
wherein the display control section includes a blind spot-non-display mode as a display mode for the side-viewing observation image, and allows at least a part of the blind spot not to be displayed and displays the side-viewing observation image on the display unit in a case in which the display mode is set to the blind spot-non-display mode.

8 . The endoscope system according to claim 4 ,
wherein the display control section includes a blind spot-non-display mode as a display mode for the side-viewing observation image, and allows at least a part of the blind spot not to be displayed and displays the side-viewing observation image on the display unit in a case in which the display mode is set to the blind spot-non-display mode.

9 . The endoscope system according to claim 1 ,
wherein the display control section allows the entire blind spot not to be displayed.

10 . The endoscope system according to claim 2 ,
wherein the display control section allows the entire blind spot not to be displayed.

11 . The endoscope system according to claim 3 ,
wherein the display control section allows the entire blind spot not to be displayed.

12 . The endoscope system according to claim 4 ,
wherein the display control section allows the entire blind spot not to be displayed.

13 . The endoscope system according to claim 5 ,
wherein the display control section allows the entire blind spot not to be displayed.

14 . The endoscope system according to claim 6 ,
wherein the display control section allows the entire blind spot not to be displayed.

15 . The endoscope system according to claim 1 ,
wherein the display control section changes a ratio of a portion, which is not to be displayed, of the blind spot.

16 . The endoscope system according to claim 15 ,
wherein the display control section changes the ratio of the portion, which is not to be displayed, of the blind spot in accordance with the movement of the insertion part.

17 . The endoscope system according to claim 16 ,
wherein the display control section changes the ratio of the portion, which is not to be displayed, of the blind spot in a case in which the insertion part is to be inserted into the object to be observed and a case in which the insertion part is to be extracted from the object to be observed.

18 . The endoscope system according to claim 15 ,
wherein the endoscope includes a direct-viewing observation unit that includes a field of view in a tip direction of the insertion part, the image acquisition unit acquires a direct-viewing observation image by using the direct-viewing observation unit, and the display control section adjusts display ratios of the side-viewing observation image and the direct-viewing observation image, and changes the ratio of the portion, which is not to be displayed, of the blind spot in accordance with the display ratios of the side-viewing observation image and the direct-viewing observation image.

19 . The endoscope system according to claim 1 , further comprising:
a nozzle that ejects a washing substance to the side-viewing observation unit to wash the side-viewing observation unit and is provided in a non-display region not to be displayed in a case in which the display control section displays the side-viewing observation image on the display unit.

20 . A method of driving an endoscope system, the endoscope system including an endoscope including a side-viewing observation unit that includes a field of view in a lateral direction of an insertion part to be inserted into an object to be observed and a protruding portion that protrudes from the insertion part and forms a blind spot in the field of view of the side-viewing observation unit, an image acquisition unit that acquires a side-viewing observation image by using the side-viewing observation unit, a display unit that displays the side-viewing observation image, and a display control section, the method comprising:
a step of allowing at least a part of the blind spot of the side-viewing observation image in which the protruding portion is shown up not to be displayed, and displaying the side-viewing observation image on the display unit by the display control section.
