Abstract
A humidity state at a distal end portion of an endoscope internal space can be reliably estimated without enlarging the diameter of an endoscope insertion part. In a humidity detecting device detecting humidity of an internal space of an endoscope, leakage currents of an imaging device and a peripheral circuit of an electric board disposed at a distal end portion of the internal space of the endoscope are detected and a humidity state of the internal space of the endoscope is determined based upon the detected leakage currents.
Claims7
A humidity detecting method for detecting humidity in an internal space of an endoscope, comprising:
- a leakage current detecting process for detecting a leakage current of an imaging device and/or a peripheral circuit of the imaging device arranged in the internal space of the endoscope;
- and
- a determining process for determining a humidity state in the internal space of the endoscope based upon the leakage current detected.
A humidity detecting device for an endoscope, the humidity detecting device for detecting humidity in an internal space of an endoscope, comprising:
- a detecting device for detecting a leakage current of an imaging device and/or a peripheral circuit of the imaging device arranged in the internal space of the endoscope;
- and
- a determining device for determining a humidity state in the internal space of the endoscope based upon the leakage current detected by the detecting device.
