Abstract: The specification discloses a method of operating an endoscope that includes a main connector at a proximal end and an insertion section extending from the main connector towards a distal end, the main connector being operatively connected with a control unit, the method including: storing operational information of one or more replaceable components of the endoscope in a first portion of a memory of the main connector; storing manufacturing information including at least one manufacturing property of the endoscope in a second portion of the memory of the main connector, wherein the first portion of the memory is logically separated from the second portion; retrieving the stored information; and conveying the retrieved information. The specification also discloses a method and system for preprocessing of imaging data in an endoscopy system to ensure that the quality of image data does not deteriorate during transmission to any external documentation systems.
