Title: Image processing method, image processing apparatus, MRI apparatus and recording medium

Abstract: For the purpose of accurately calculating the average value M of original complex observed signals S from an absolute-value image produced by the complex observed signals S, in Step A1, the average value Ma of pixel values |S| of the absolute-value image in a local region is calculated by: Ma=.SIGMA.|S|/k, wherein the number of pixels in the local region is represented as k. In Step A2, the average value M of the original complex observed signals S is calculated by the following equation: M=.alpha.f.sup.-1 (Ma/.alpha.), wherein f.sup.-1 (Ma/.alpha.) is an inverse function of the function Ma/.alpha.=f(M/.alpha.) represented as: Ma/.alpha.=.intg..intg.{|M/.alpha.+(X+iY)|exp{-(X.sup.2+Y.sup.2)/2}/2.pi.- }dX dY.
