A METHOD FOR CALCULATING GAIN CORRECTION FACTORS IN A DIGITAL IMAGING SYSTEM |
摘要 |
A method for developing a set of gain correction coefficients corrected for structural noise to be used in correcting the digital values representing an image captured by a pixilated detector having a plurality of individual sensors. The gain correction coefficients are developed by first obtaining a first set gain correction coefficients (30) using a flat exposure (20) and adjusting the individual sensor gain output so that all sensors produce the same output value, and then applying a smoothing filter (40) to the first set of gain correction coefficients to obtain a new set of corrected gain correction coefficients. |
