A method and apparatus for processing a radiation image in a radiation image recording system in which a stimulable phosphor is stimulated with a scanning stimulating beam and the light emitted from the stimulable phosphor upon stimulation by the stimulating beam is detected by a detector which generates an output which is processed and used for recording a visible image on a recording material. In the processing of the detected output, an operation represented by a formula S'=Sorg+ beta (Sorg-Sus) is conducted, where Sorg is the original image signal detected by the detector, beta is an emphasis coefficient, and Sus is an unsharp mask signal corresponding to a super-low spatial frequency at every scanning point. The unsharp masking process may be performed together with a gradation process, reduction of image size, smoothing process and the like. Further, the emphasis coefficient may be varied with either the original image signal Sorg or the unsharp mask signal Sus.
