  • Compensating for image sensor profile variations
    Patent number: 9118785
    Abstract: Disclosed is a method of scanning a physical medium by an image scanner comprising a first image sensor having a plurality of image sensor elements that provide an image, and a first light source associated with the first image sensor, the method comprising: guiding light from the first light source towards a first group of image sensor element(s); recording a first light calibration value using the first group of image sensor element(s). The method further comprises repeating the above step by using a second group of image sensor element(s) thus resulting in a second light calibration value; generating a first compensation signal for image sensor elements positioned between the first and the second group of image sensor element(s) by processing the first and the second light calibration value together; compensating said image signals provided by the first image sensor using the first compensation signal.
