Endoscope system, endoscope video processor and method of driving endoscope system

摘要

A light source device emits normal illumination light and special illumination light interchangeably at a charge-storage time of an imaging device. A DRP is reconfigurable between a normal image producing circuit and a special image producing circuit. A CPU instructs the reconfiguration of the DRP when detecting that a vertical synchronization signal from a drive circuit falls to zero level. The DRP gains an access to a configuration memory to load circuit information of the normal or special image producing circuit. According to the circuit information loaded, the DRP changes functions and interconnection of processor elements.
