Abstract

Rotate instructing switches 26, 27, and 28 of an operating remote controller 5 are pressed and then a CPU 12 controls image processing of an image pickup processing portion 8, a direction calculation processing portion 10, and a rotating-image processing portion 9 in accordance with an operating signal to rotate and display a screen 21 displayed on a screen of an LCD 4A. Touch-panel type direction instructing portions arranged on the LCD 4A are operated, thereby supplying operating signals to the CPU 12 via a touch panel controller 4a. The CPU 12 determines, by using a determining area table arranged in a ROM 13 based on the operating signal, which direction instructing portion is pressed. Simultaneously, the CPU 12 calculates the moving direction and the amount of movement of an image by a direction processing portion 11 and the direction calculation processing portion 10, and controls the driving of a driving unit 7 based on a calculated result.

Claims

1. An endoscope device comprising:

an endoscope that can be inserted to a portion to be observed and has an inserting portion having image pickup means at the distal-end side thereof that obtains an observed image;

an image pickup processing portion that converts the observed image of the endoscope into an image signal that can be displayed on a display unit;

a direction instructing portion that instructs a moving direction of a display image displayed on the display unit;

a direction calculation processing portion that processes the amount of movement of the display image in accordance with an instruction from the direction instructing portion; and

a rotation instructing portion that instructs the rotation of the display image of the display unit at an arbitrary angle,

wherein the direction calculation processing portion corrects a moving direction of the display image based on an instruction of the rotation instructing portion.

2. An endoscope device according to claim 1, further comprising:

an image processing control unit that controls the image pickup processing portion based on a processed result of the direction calculation processing portion.

3. An endoscope device according to claim 2, further comprising:

a rotating-image processing portion that performs rotating-image processing of the observed image displayed on the display unit based on the instruction from the rotation instructing portion.

4. An endoscope device according to claim 3, wherein the rotating-image processing portion processes the image size to arbitrarily be changed so as to include the entire display image subjected to the rotating-image processing on a display screen of the display unit.

5. An endoscope device according to claim 2, wherein the direction instructing portion and the direction calculation processing portion are arranged in an endoscope control unit connected to the endoscope by communication means.

6. An endoscope device according to claim 1, further comprising:

a rotating-image processing portion that performs rotating-image processing of the observed image displayed on the display unit based on the instruction from the rotation instructing portion.

7. An endoscope device according to claim 6, wherein the rotating-image processing portion processes the image size to arbitrarily be changed so as to include the entire display image subjected to the rotating-image processing on a display screen of the display unit.

8. An endoscope device according to claim 1, wherein the direction instructing portion and the direction calculation processing portion are arranged in an endoscope control unit connected to the endoscope by communication means.

9. An endoscope device according to claim 8, wherein the endoscope control unit is a personal computer.

10. An endoscope device comprising:

an endoscope that can be inserted to a portion to be observed and has an inserting portion having image pickup means at the distal-end side thereof that obtains an observed image;

an image pickup processing portion that converts the observed image of the endoscope into an image signal that can be displayed on a display unit;

a direction instructing portion that instructs a processing of a bending direction of the inserting portion;

a direction calculation processing portion that processes the bending direction of the inserting portion in accordance with an instruction from the direction instructing portion;

a rotation instructing portion that instructs the rotation of the display image of the display unit at an arbitrary angle; and

a driving control unit that controls the operation of the inserting portion of the endoscope based on a processed result of the direction calculation processing portion;

wherein the direction calculation processing portion corrects a bending direction of the inserting portion of the endoscope based on an instruction of the rotation instructing portion.

11. An endoscope device according to claim 10, further comprising:

a rotating-image processing portion that performs rotating-image processing of the observed image displayed on the display unit based on the instruction from the rotation instructing portion.

12. An endoscope device according to claim 11, wherein the rotating-image processing portion processes the image size to arbitrarily be changed so as to include the entire display image subjected to the rotating-image processing on a display screen of the display unit.

13. An endoscope device according to claim 10, wherein the direction instructing portion and the direction calculation processing portion are arranged in an endoscope control unit connected to the endoscope by communication means.

14. An endoscope device comprising:

an image pickup processing portion that converts an observed image obtained by image pickup means of an endoscope inserted to a portion to be observed, into an image signal that can be displayed on a display unit;

a direction instructing portion that instructs a moving direction of a display image displayed on the display unit;

a direction calculation processing portion that processes the amount of movement of the display image in accordance with an instruction from the direction instructing portion; and

a rotation instructing portion that instructs the rotation of the display image of the display unit at an arbitrary angle,

wherein the direction calculation processing portion corrects a moving direction of the display image based on an instruction of the rotation instructing portion.

15. An endoscope device endoscope device according to claim 14, further comprising:

a driving control unit that controls the operation of the inserting portion of the endoscope based on a processed result of the direction calculation processing portion.

16. An endoscope device according to claim 14, further comprising:

an image processing control unit that controls the image pickup processing portion based on a processed result of the direction calculation processing portion.
