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.

A method for enabling uniform white balancing of a first viewing element and a second viewing element in a tip of an endoscope, wherein the first viewing element is positioned on a distal face of the tip and the second viewing element is positioned on a side of the tip, the method comprising:
- providing a housing defined by an opening leading into an enclosed volume, wherein the opening is configured to snugly receive the endoscopic tip such that external light is prevented from entering through the opening when the endoscopic tip is inserted therein, and such that a field of view of the first viewing element and the second viewing element are blocked by the housing;
- receiving the endoscopic tip within the opening;
- positioning the first viewing element at a first predefined distance from a surface area of the housing;
- white balance processing images obtained by the first viewing element and the second viewing element;
- and
- splitting a white balance command to a digital signal processor associated with said first viewing element and said second viewing element.
