Abstract

An endoscope device having an imaging element for imaging an observation image of a subject, an endoscope having a grippable operation section, a video image displaying device for converting an image signal from imaging means into a video image and displaying it, a first supporting section for supporting the video image displaying device so that the video image displaying device is pivotable about its longitudinal axis or about an axis substantially parallel to the longitudinal axis, and video image rotating means for rotating the image of the subject displayed on the video image displaying device about an axis substantially orthogonal to the screen of the video image displaying device.

Claims

1. An endoscope device comprising:

an imaging device for imaging an observation image of a subject;

an endoscope having a grippable operation section;

a video image displaying device for converting an image signal from the imaging device into a video image and displaying the video image;

a first supporting section that is provided in the operation section and supports the video image displaying device so that the video image displaying device is pivotable around a longitudinal axis of the operation section or about an axis substantially parallel to the longitudinal axis; and

a video image rotating device for rotating the image of the subject displayed on the video image displaying device about an axis substantially orthogonal to the screen of the video image displaying device.

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

a direction and angle detecting device that, when the video image displaying device is pivoted relative to the operation section, detects a direction in which the video image displaying device has been pivoted and an angle by which the video image displaying device has been pivoted, wherein

the video image rotating device rotates the image of the subject that is displayed on the video image displaying device in an opposite direction from the pivot direction detected by the direction and angle detecting device and by the same amount as the pivot angle detected by the direction and angle detecting device.

3. The endoscope device according to claim 1, further comprising:

a second supporting section that supports the video image displaying device so that the video image displaying device is pivotable around an axis that is perpendicular to the longitudinal axis or to an axis that is substantially parallel with the longitudinal axis.

4. The endoscope device according to claim 1, wherein

the first supporting section is able to arbitrarily fix the position of the video image displaying device relative to the operation section and maintain the relative positions of the two as long as there is no intentional external application of pressure.

5. The endoscope device according to claim 1, wherein

the second supporting section is able to arbitrarily fix the position of the video image displaying device relative to the operation section and maintain the relative positions of the two as long as there is no intentional external application of pressure.

6. The endoscope device according to claim 1, further comprising

a pivot drive device that drives the video image displaying device in a pivot direction around the longitudinal axis or around an axis that substantially parallel with the longitudinal axis.

7. The endoscope device according to claim 1, further comprising a rotation operation section that is operated by the operator or by another person, wherein

the video image rotating device rotates an image of the subject displayed on the video image displaying device in a predetermined direction in accordance with an operation of the rotation operation section.

8. The endoscope device according to claim 1, further comprising:

an image recording device that records an image of the subject displayed on the video image displaying device; and

an image recording selection device that selects whether to record on the image recording device an image of the subject that is displayed on the video image displaying device in a state prior to the video image rotating device being operated or in a state after the video image rotating device has been operated.
