Abstract:
1. An image processing method of performing a temporal difference determination process based on at least diagnosis information associated with first image data or diagnosis information associated with second image data, comprising: determining points on the second image data, the points corresponding to respective representative points on the first image data; calculating a shift vector indicating the difference between each representative point and a corresponding point; calculating modification coefficients by performing two-dimensional fitting on shift vectors weighted by weighting factors, the weighting factors being determined based on region information included in the diagnosis information; modifying coordinates of at least one of the first image data and the second image data in accordance with the modification coefficients; determining a difference between the first image data and the second image data aligned with each other; and displaying a result of the difference determination and the diagnosis information, wherein the manner of displaying the result of the difference determination process is switched depending on the diagnosis information.
