Abstract
A method of input scanning an image using a detector comprising an array of radiation sensors, the method comprising PA1 1) exposing the radiation sensors to radiation from the image over a plurality of sampling periods, and for each respective sampling period: PA1 2) obtaining a single data value from each radiation sensor; PA1 3) summing the data values obtained during the sampling period; PA1 4) determining a peripheral response value in accordance with the sum obtained in step 3), wherein the peripheral response value for each sampling period is determined independently of the peripheral response values for the other sampling periods; and PA1 5) modifying the data values in accordance with the peripheral response value obtained in step 4).
