ELECTRONIC ENDOSCOPE SYSTEM

摘要

An electronic endoscope system including: an operation portion; an insertion portion including on a distal end side thereof a bending portion, and connected to the operation portion so as to be rotatable with respect to the operation portion, a bending direction of the bending portion changing depending on the rotation; an image pickup device disposed in the insertion portion, for generating an image of a subject; a physical quantity generation portion that generates a physical quantity which changes depending on the rotation of the insertion portion; a detection portion that detects and outputs the physical quantity generated by the physical quantity generation portion; a rotation angle calculation portion that receives the physical quantity outputted from the detection portion and calculates a rotation angle of the insertion portion; and a display portion that displays the image of the subject and information corresponding to the rotation angle of the insertion portion.

1. An electronic endoscope system comprising:
an operation portion configured to be operable by an operator; an insertion portion including on a distal end side thereof a bending portion, the insertion portion being connected to the operation portion so as to be rotatable with respect to the operation portion, a bending direction of the bending portion changing depending on the rotation; an image pickup device disposed in the insertion portion and configured to generate an electronic image by photoelectrically converting an optical image of a subject; a physical quantity generation portion configured to generate a physical quantity which changes depending on the rotation of the insertion portion; a detection portion configured to detect the physical quantity generated by the physical quantity generation portion and output the detected physical quantity; a rotation angle calculation portion configured to receive the physical quantity outputted from the detection portion and calculate a rotation angle of the insertion portion; and a display portion configured to display the image of the subject generated by the image pickup device and information generated based on the calculated rotation angle, the information corresponding to the rotation angle of the insertion portion.
