To provide a magnetic domain image processing device and a magnetic domain image processing method that are able to evaluate distortion of an electromagnetic steel sheet in more detail.SOLUTION: A magnetic domain image processing device for handling a magnetic domain image, comprises: an image acquisition unit that acquires a reference magnetic domain image, which is a magnetic domain image obtained when a stimulus having a reference intensity that is an intensity as a reference is applied to a sample, a positive magnetic domain image, which is a magnetic domain image obtained when a stimulus having an intensity higher than the reference intensity is applied to the sample, or a negative domain image, which is a magnetic domain image obtained when a stimulus having an intensity lower than the reference intensity is applied to the sample; and an image generation unit that, based on the reference magnetic domain image, the position magnetic domain image, and the negative magnetic domain image, generates a stress distribution image indicating a distribution of stress regions, which are regions in which stress has been caused.SELECTED DRAWING: Figure 4 【課題】電磁鋼板の歪みをより詳細に評価することが可能な磁区画像処理装置及び磁区画像処理方法を提供する。【解決手段】磁区画像を扱う磁区画像処理装置であって、基準となる強度である基準強度の刺激を試料に与えたときに得られる磁区画像である基準磁区画像と、前記基準強度よりも高い強度の刺激を前記試料に与えたときに得られる磁区画像である正磁区画像または前記基準強度よりも低い強度の刺激を前記試料に与えたときに得られる磁区画像である負磁区画像を取得する画像取得部と、前記基準磁区画像と前記正磁区画像と前記負磁区画像とに基づいて、応力が発生している領域である応力領域の分布を示す応力分布画像を生成する画像生成部を備えることを特徴とする。【選択図】図４
