Abstract
In a radiation image system wherein a stimulable phosphor carrying a radiation image stored therein is exposed to stimulating rays which cause it to emit light in proportion to the radiation energy stored, and the emitted light is detected and converted to an electric signal which is processed to reproduce a visible image, several reference gradation correction curves are created on an orthogonal system of signal level-optical density coordinates. One of the reference curves is selected and rotated around a point on the reference curve on the coordinate system, and/or parallel-shifted on the coordinate system to obtain a desired gradation correction curve.
