Abstract
The specification describes a white balance enclosure for use with a tip of a multi-viewing elements endoscope. The white balance enclosure is used to provide a reference white background to the plurality of viewing elements when the tip is positioned within the white balance enclosure and a white balance circuit is used to calculate and store reference white balance values based on white field/test feed signals generated by the plurality of viewing elements exposed to the reference white background.
