Abstract

A system and method for calibrating an endoscope having the camera and the light source close to each other in an enclosed environment. The system includes a colour chart plate, being specularly reflecting, having radially extending colour patches, and a circular central achromatic bright field that can handle the automatic gain control of the camera. The colour chart can be mounted into a container unit having mechanically connected holders to support the endoscope arm.
