PROBLEM TO BE SOLVED: To solve the problem that a defect of image data cannot be restored appropriately.SOLUTION: A defective region is extracted from defective image data including the defective region, a plurality of correspondent image data items in which regions corresponding to the defective region are not defective, are extracted, and a first pixel value change amount in the regions of the plurality of extracted correspondent image data items corresponding to the defective region is extracted. A plurality of reference image data items which have an imaging time difference equal to an imaging time difference between the plurality of correspondent image data items and of which the pixel value change amount is equal to the first pixel value change amount are extracted. Comparative image data of which the imaging time difference is equal to an imaging time difference between the correspondent image data and the defective image data and which corresponds to the reference image data is extracted. In the plurality of reference image data items and the comparative image data, a second pixel value change amount in a region of which the pixel value change amount is equal to the first pixel value change amount, is extracted and on the basis of the first pixel value change amount and the second pixel value change amount, the defective region is restored.SELECTED DRAWING: Figure 1 |
