Abstract
An object of the invention is to provide an endoscope capable of continuously grasping a direction which a distal end portion of an endoscope faces even when a bending operation is performed. The endoscope of the invention is provided with: a first image pickup optical system provided at a distal end of an insertion portion; a bending portion provided in a vicinity of a distal end portion of the insertion portion and configured to be bendingly operated by a proximal side operation; and a second image pickup optical system disposed on the bending portion and configured so that the distal end of the insertion portion is included within a field-of-view angle.

An endoscope comprising:
- a first image pickup optical system provided at a distal end of an insertion portion;
- a bending portion provided in a vicinity of a distal end portion of the insertion portion and configured to be bendingly operated by a proximal side operation;
- and
- a second image pickup optical system disposed on the bending portion, the second image pickup optical system being configured so that the distal end of the insertion portion is included within a field-of-view angle of the second image pickup optical system;
- wherein, when the bending portion is in a non-bending state, an optical axis of the first image pickup optical system is fixed to be substantially parallel to an optical axis of the second image pickup optical system.
An endoscope system comprising:
- an endoscope comprising:
- a first image pickup unit including a first image pickup optical system and a first image pickup device, the first image pickup unit being provided at a distal end of an insertion portion;
- a bending portion provided in a vicinity of a distal end portion of the insertion portion and configured to be bendingly operated by a proximal side operation;
- and
- a second image pickup unit disposed on the bending portion the second image pickup unit including a second image pickup optical system and a second image pickup device, wherein the second image pickup optical system is configured so that the distal end of the insertion portion is included within a field-of-view angle of the second image pickup optical system, wherein, when the bending portion is in a non-bending state, an optical axis of the first image pickup optical system is fixed to be substantially parallel to an optical axis of the second image pickup optical system;
- an image processing control apparatus configured to receive image signals from the first image pickup unit and the second image pickup unit and perform image processing, and control the first image pickup unit and the second image pickup unit;
- and
- an image display apparatus configured to receive an image signal outputted from the image processing control apparatus and display an image.
An endoscope comprising:
- a first image pickup optical system provided at a distal end of an insertion portion;
- a bending portion provided in a vicinity of a distal end portion of the insertion portion and configured to be bendingly operated by a proximal side operation;
- and
- a second image pickup optical system fixed at a predetermined position on the bending portion, the second image pickup optical system being configured at the predetermined position such that the distal end of the insertion portion is included within a field-of-view angle of the second image pickup optical system whether the bending portion is in an unbent state or in a bent state.
