Abstract: A method of creating an image 4 obtained from say a camera 1 to obtain a substantially linear representation of the brightness of the image includes, for each of a set of pixels (x, y) in a two dimensional array, calculating, in a computer 3, an estimate of the true image intensity (ixy) as a weighted average of n samples of the apparent image intensity (vn,xy). This is calculated as: i ^ xy = ? n ? ? ( w n , xy ? ( v n , xy - C KT n ) ) ? n ? w n , xy = 1 K ? ? n ? ? ( w n , xy ?
