Cavity insert device using fuzzy theory

A cavity insert device comprising:

• an insert section to be inserted into a cavity;
• means provided at a distal end of said insert section for observing or treating the inside of said cavity and so on;
• detection means for detecting a plurality of status signals related to an environmental condition of said device;
• and
• fuzzy control means for synthetically processing said plurality of status signals according to inference rules from said detection means and controlling said observation or treatment means before starting an insert operation of said insert section, said fuzzy control means being includes means for changing inference rules used during control of said observation or treatment means.

An endoscope device comprising:

• image sensing means for converting an image of an object into an electrical signal;
• detection means for detecting object information from the electrical signal outputted from said image sensing means;
• operational element means related to an insert or observing operation of an endoscope;
• and
• fuzzy inference means for receiving the object information from said detection means as input signals, and synthetically processing said input signals to output a control signal to control said operational element means.

An endoscope system comprising:

• an endoscope having a slender insert section;
• controlled element means provided to be controlled for setting said endoscope to a desired observing state;
• information signal detecting means for producing a plurality of information signals from outside said endoscope to control said controlled element means;
• and
• fuzzy inference means for carrying out an arithmetic operation to compositely process said plurality of information signals and producing a control signal to control said controlled element means from a result of said arithmetic operation.

An endoscope device comprising:

• an endoscope comprising;
• a slender insert section, and
• image sensing means to produce an image signal corresponding to an image of an object;
• detection means for detecting a plurality of items of object information from the image signal outputted from said image sensing means;
• fuzzy inference means for carrying out an arithmetic operation to compositely infer said plurality of items of object information and producing a control signal from a result of said arithmetic operation;
• and
• controlled element means controlled by said control signal to set said endoscope to a desired state for observation and inspection.
