Claim 0:
1. A method for adjusting white balance in a digital imaging process for use with an endoscope in ambient light deficient environments comprising:
providing, during a training period, a cap that selectively covers a distal end of a lumen of the endoscope such that the cap is blocking external illumination to each pixel in a pixel array;
illuminating, during the training period, an interior of the cap using a controlled source of electromagnetic radiation;
determining, after the endoscope reaches its operating temperature during the training period, white balance coefficients while the cap is covering the distal end of the lumen and while illuminating the interior of the cap by the controlled source of electromagnetic radiation;
removing the cap from the distal end of the lumen at the operating temperature for the endoscope;
in response to removing the cap from the distal end of the lumen, sensing electromagnetic radiation with the pixel array to create an image frame; and
correcting white balance of the image frame using the white balance coefficients.
