Endoscope shape detecting apparatus
First Claim
1. An endoscope shape detecting apparatus comprising:
- a device detecting portion comprising;
one of a group of a plurality of magnetic field generating devices and a group of a plurality of magnetic field detecting devices disposed inside an insertion portion of an endoscope to be inserted into a subject; and
the other of the groups of devices being disposed outside the subject,wherein the device detecting portion is configured to detect respective positions of the one group of devices disposed inside the insertion portion by using positions of the other group of devices as reference;
a monitor comprising a screen, wherein the monitor is configured to display an endoscope image obtained by the endoscope on the screen, and to selectively display a model image of a shape of the insertion portion of the endoscope; and
a processor comprising hardware, wherein the processor is configured to;
estimate the shape of the insertion portion of the endoscope based on the respective positions detected by the device detecting portion;
generate the model image of the estimated shape of the insertion portion of the endoscope;
perform image analysis on the endoscope image obtained by the endoscope;
judge whether a predetermined condition occurred based on at least one of the estimated shape of the insertion portion of the endoscope and a result of the image analysis on the endoscope image; and
control the monitor to automatically display the model image with the endoscope image on the screen of the monitor upon judgment that the predetermined condition occurred.

Abstract
A detecting apparatus includes: a change-over switch for switching on/off display of a scope model on a liquid crystal monitor; a position calculating portion for calculating respective positions of source coils; a scope model generating portion for generating a scope model of an electronic endoscope based on the respective positions of the source coils calculated by the position calculating portion; and a selector for selectively outputting to the liquid crystal monitor a display-pause-time image stored in a display-pause-time image storing portion and a scope model image from the scope model generating portion; and a control portion for controlling each of these portions. The detecting apparatus thus displays an insertion shape of the endoscope at a timing as needed.
