FIELD: information technology.
SUBSTANCE: information processing device includes a spatial filtering means for performing spatial filtering in a frequency band based on a spatial frequency of an object for image data of a current frame; and a recursive filtering means for performing recursive filtering by obtaining image data, processed prior to the current frame, from a storage device, multiplying the obtained image data by a coefficient α (α<1), adding the image data multiplied by the coefficient α to the image data of the current frame after the spatial filtering, and storing the image data after addition in the storage device.
EFFECT: broader functional capabilities of image processing by ensuring noise reduction, thereby suppressing the effect of radiation on the object.
