The invention provides a method of image correction processing which comprises altering area image intensity values of an image according to an dynamic range compression image transform. The output image intensity of an area is altered, compared to the input image intensity, according to an area amplification coefficient. The amplification coefficient of an area is varied in dependence upon the amplification coefficient of at least one other neighbouring area. The invention preserves contrast in images that have been processed in order to compress dynamic range. |
