Abstract
In a radiation image processing method, unsharp mask signals Sus.k are calculated by averaging original image signals detected within predetermined ranges surrounding each scanning point on an image-recorded stimulable phosphor, and at least a single attenuation coefficient .beta.l among attenuation coefficients .beta.k corresponding to the unsharp mask signals Sus.k is adjusted to be a constant within the range of 0<.beta.l wherein .beta.l.noteq.1. An operation represented by a formula ##EQU1## where Sb1 and Sb2 each denote the original image signal or an image signal obtained by intermediate processing of the original image signal, and S' denotes an image signal obtained by the operation processing is carried out by use of the attenuation coefficient .beta.l, whereby spatial frequency components above the spatial frequency component which the unsharp mask signal Sus.l corresponding to the attenuation coefficient .beta.l has are attenuated.
