Industrial endoscope apparatus

1. An endoscope apparatus, comprising:

an insertion portion configured to include a bend portion;

an image pickup portion configured to capture an image of an object to be inspected;

an operation portion configured to perform a bending operation of the bend portion;

a storage portion configured to store at least an image of the object to be inspected as a recorded image;

a display portion configured to display the image, the display portion having a fixed positional relationship relative to the operation portion; and

a display control portion configured to:

determine a display orientation of superimposition information, the superimposition information being superimposed on the image;

display the image captured by the image pickup portion without rotating the image; and

display the superimposition information according to the display orientation of the superimposition information,

wherein the display control portion determines the display orientation of the superimposition information based on a position of the endoscope apparatus; and

wherein the display control portion does not rotate the image captured by the image pickup portion.

2. The endoscope apparatus according to claim 1 , wherein the display control portion rotates the superimposition information at 180 degrees relative to the image captured by the image pickup portion when the position of the endoscope apparatus is inverted.

3. The endoscope apparatus according to claim 1 , wherein the display control portion rotates the superimposition information at 90 degrees relative to the image captured by the image pickup portion when the position of the endoscope apparatus is in a right side rotated state or a left side rotated state.

4. The endoscope apparatus according to claim 1 , wherein the display control portion generates non-rotated superimposition information and rotated superimposition information as the superimposition information, and the display control portion selects one of the non-rotated superimposition information and the rotated superimposition information to display the superimposition information.

5. An endoscope apparatus comprising:

an insertion portion configured to include a bend portion;

an image pickup portion configured to capture an image of an object to be inspected;

an operation portion configured to perform a bending operation of the bend portion;

a storage portion configured to store at least an image of the object to be inspected as a recorded image;

a display portion configured to display the image, the display portion having a fixed positional relationship relative to the operation portion; and

a display control portion configured to:

determine a display orientation of at least one of the recorded image and a Graphical User Interface; and

display the at least one of the recorded image and the Graphical User Interface according to the display orientation of the at least one of the recorded image and the Graphical User Interface;

wherein the display control portion determines the display orientation of the at least one of the recorded image and the Graphical User Interface based on a position of the endoscope apparatus; and

wherein the display control portion rotates both of the recorded image and the Graphical User Interface at 180 degrees when the position of the endoscope apparatus is inverted.

6. An endoscope apparatus comprising:

an insertion portion configured to include a bend portion;

an image pickup portion configured to capture an image of an object to be inspected;

an operation portion configured to perform a bending operation of the bend portion;

a storage portion configured to store at least an image of the object to be inspected as a recorded image;

a display portion configured to display the image, the display portion having a fixed positional relationship relative to the operation portion; and

a display control portion configured to:

determine a display orientation of at least one of the recorded image and a Graphical User Interface; and

display the at least one of the recorded image and the Graphical User Interface according to the display orientation of the at least one of the recorded image and the Graphical User Interface;

wherein the display control portion determines the display orientation of the at least one of the recorded image and the Graphical User Interface based on a position of the endoscope apparatus; and

wherein the display control portion rotates both of the recorded image and the Graphical User Interface at 90 degrees when the position of the endoscope apparatus is in a right side rotated state or a left side rotated state.

7. A method of displaying an image of an object to be inspected by an endoscope apparatus, the method comprising:

capturing the image using the endoscope apparatus;

displaying the image on a display portion of the endoscope apparatus;

determining a display orientation of superimposition information, the superimposition information being superimposed on the image, and the display orientation of the superimposition information being determined based on a position of the endoscope apparatus;

displaying the image without rotating the image; and

displaying the superimposition information according to the display orientation of the superimposition information without rotating the displayed image;

wherein in playing back a recorded image stored in a storage portion of the endoscope apparatus, the method further comprises:

determining a display orientation of at least one of the recorded image and a Graphical User Interface; and

displaying the at least one of the recorded image and the Graphical User Interface according to the display orientation of the at least one of the recorded image and the Graphical User Interface.

8. The method according to claim 7 , further comprising rotating the superimposition information at 180 degrees relative to the image when the position of the endoscope apparatus is inverted without rotating the image.

9. The method according to claim 7 , further comprising rotating the superimposition information at 90 degrees relative to the image when the position of the endoscope apparatus is in a right side rotated state or a left side rotated state without rotating the image.

10. The method according to claim 7 , further comprising generating non-rotated superimposition information and rotated superimposition information as the superimposition information, and selecting one of the non-rotated superimposition information and the rotated superimposition information to display the superimposition information.

11. The method according to claim 7 , wherein determining the display orientation of the at least one of the recorded image and the Graphical User Interface comprises determining the display orientation of the at least one of the recorded image and the Graphical User Interface based on the position of the endoscope apparatus.

12. The method according to claim 11 , further comprising rotating both of the recorded image and the Graphical User Interface at 180 degrees when the position of the endoscope apparatus is inverted.

13. The method according to claim 11 , further comprising rotating both of the recorded image and the Graphical User Interface at 90 degrees when the position of the endoscope apparatus is in a right side rotated state or a left side rotated state.
