PROBLEM TO BE SOLVED: To provide a grain diameter measuring method, a grain diameter measuring apparatus and a grain diameter measuring program, capable of reducing variation in measurement results obtained by measurers.;SOLUTION: A grain diameter measuring method includes: an image preparation step of preparing a processing target image in which a crystal structure of a predetermined region in a material is captured and a reference image used for exposing profile regions of crystal grains in the crystal structure; an image laminating step of laminating the reference image under the processing target image; a binarization step of performing binarization processing on a pixel value of each pixel constituting the processing target image, by taking a predetermined pixel value as a threshold; a transparent processing step of making transparent a region in the processing target image which corresponds to a region of a predetermined pixel value having a higher lower limit than the binarization threshold; a threshold adjustment step of performing binarization while adjusting the threshold so as to blacken a while outline region of the crystal grains contained in the crystal structure, which is exposed by laminating the processing target image and the reference image; and a grain diameter measuring step of measuring an average grain diameter of the crystal grains contained in the crystal structure by using a cutting method.;COPYRIGHT: (C)2016,JPO&INPIT
