IMAGE PROCESSING DEVICE, RADIATION IMAGE IMAGE PICKUP SYSTEM, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要: Provided are the following: image processing that can improve quality of a composite mammogram image; radiation pickup system; an method; and program. A control unit 40 sets incidence angle, with respect to detection surface 27 detector 26, which is incident on such so angle plurality mutually different angles, including (0 degrees) becomes normal direction 27, obtains projection images picked up by 26 in accordance angles and/or reconstructed using images. In addition, generates first combined Ms1 basis obtained Also, reference second Ms2 combining high-frequency Msmh having high frequency component higher than pre-determined Ms1, low-frequency Tp1 no more zero-degree Tp0.
