SYSTEM FOR OBTAINING CLEAR ENDOSCOPE IMAGES

摘要

An endoscopic system including an endoscope, a light source for the endoscope and at least one image sensor for capturing a plurality of images of a body cavity. The light source is configured to emit light from the endoscope and into the body cavity such that the light is reflected off of a plurality of locations in the body cavity. The system also includes a control system for controlling both the light source and the at least one image sensor to vary parameters of the light source and the at least one image sensor such that the plurality of images have underexposed and overexposed regions. The endoscopic system could alternatively include a variable-attenuator element device adjacent the image sensor and configured to be located between the body cavity and the image sensor for capturing a single clear image with the image sensor.

1. A method of obtaining a clear endoscopic image comprising:
providing an endoscope; providing a light source for the endoscope; providing at least one image sensor for capturing a plurality of images of a body cavity; emitting light from the endoscope into the body cavity; reflecting the light off of a plurality of locations in the body cavity; capturing the plurality of images of the light with the at least one image sensor; controlling both the light source and the at least one image sensor to vary parameters of the light source and the at least one image sensor such that the plurality of images have underexposed and overexposed regions; and combining the plurality of images to result in the clear endoscopic image.
