PHOTOGRAPHING LIGHT QUANTITY CONTROLLER FOR ENDOSCOPE

摘要

A photographing light quantity controller for an endoscope is used to control the quantity of illuminating light when a photograph is to be taken through the endoscope. The photographing light quantity controller comprises a light source for supplying light for illuminating an object to the endoscope, and a device for detecting an illuminating condition in an observation state before a photographing operation is initiated. A device is also provided for controlling the brightness of illuminating light that is supplied from the light source to the endoscope during the photographing operation on the basis of a signal that is detected by the device for detecting an illuminating condition in the observation state.
