DEVICE, SYSTEM AND METHOD FOR PROCESSING IMAGE, STORAGE MEDIUM AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image processor which easily and surely provides a processed image where only an object to be a target is emphasized by obtaining a configuration which efficiently performs a frequency emphasis processing with a more limited frequency band. SOLUTION: A smoothing image obtaining means 113 obtains one smoothing image based on a plurality of smoothing images obtained from an object image(a radiation image). A differential component obtaining means 114 obtains a differential component between the object image and the smoothing image which is obtained by the smoothing image obtaining means 113. A differential component converting means 115 converts the differential component obtained by the differential component obtaining means 114 into a non-linear component. A differential component adding means 116 adds the differential component after conversion in the differential component converting means 115 into the object image.
