Abstract
Provided is a method of removing a moiré in a fluoroscopic X-ray image that preliminarily complements a defective pixel with no disturbance in regularity of a moiré pattern to ensure that no trace of the defective pixel and no ghost thereof create even when the fluoroscopic X-ray image contains the defective pixel. A moiré frequency derivation section determines frequency of the moiré that appears in the fluoroscopic X-ray image, a defective pixel preliminary complement section forms a preliminary complement image, a moiré removal section conducts frequency analysis of the preliminary complement image to form a moiré removed image, an image smoothing section performs an image smoothing process to the preliminary complement image to form a smoothed image suitable for complement of the defective pixel, and a first defective pixel recomplement section recomplements the defective pixel by superimposing the moiré removed image on the smoothed image.
