ABSTRACT:
An endoscope insertion controlling apparatus includes a region extracting apparatus for extracting a plurality of regions corresponding to brightness from an endoscope image, for example, by setting a plurality of threshold levels of brightness and a judging apparatus for determining endoscope inserting conditions such as an inserting direction and progress speed based on an arrangement of the respective regions extracted by the region extracting apparatus. An endoscope inserting direction detecting apparatus includes a light receiving apparatus for receiving light from a visual field narrower than an ordinary observing field of the endoscope, a scanning apparatus for scanning the visual field of the light receiving apparatus and a judging apparatus for determining an endoscope inserting direction based on the received light amount by the light receiving apparatus in the respective visual field directions obtained by scanning the visual field of the light receiving apparatus by the scanning apparatus.
