Abstract:
1. A method for configuring an imaging system, comprising: exposing a two dimensional pixel array within the imaging system to a scene having a known radiance; capturing a predetermined number of image signal frames of the known radiance scene; discarding a predetermined number of pixel values in at least one column of the two dimensional pixel array when each frame is captured based on gray scale values of the pixel values; thereafter, finding a column white value for each column of the two dimensional pixel array when each frame is captured; averaging the column white values to determine an average column white value for each column of the two dimensional pixel array; comparing each average column white value to a predetermined reference value for each column, and therefrom determining a correction value for each column of the two dimensional pixel array; and storing each correction value in a storage location for retrieval by the imaging system.
