Abstract
In a radiation image recording system for recording a processed image on a recording medium by frequency emphasis processing and gradation processing of radiation image data from an object to be examined, an image processing apparatus performs frequency emphasis processing and gradation processing of the radiation image data for a later image recording stage. The image processing apparatus calculates two unsharp mask data Sus1 and Sus2 for two different mask sizes, and substantially simultaneously forms two processed image data by frequency emphasis processing and gradation processing of the radiation image data using the unsharp mask data Sus1 and Sus2.
