Abstract

PURPOSE: To improve contrast and thus to improve diagnostic performance by a method wherein a frequency response from a very low frequency domain is emphasized, and a frequency domain essential for diagnosis is emphasized.
CONSTITUTION: An accumulative phosphor material is scanned, a radiant ray image information recorded therein is read, and after conversion into an electric signal, it is reproduced on a recording material as a visible image. A nonsharp mask signal Sus corresponding to a very low space frequency at each scanning point is obtained, and by carrying out an operation S'=Sorg+β(Sorg-Sus), wherein Sorg is an original image signal read from the phosphor and β a coefficient of emphasis, a frequency component coming over the very low space frequency is emphasized.
