The finite strain measurement based on the image analysis is suggested by using the Natural Strain theory proposed in this paper. The utility of this measurement method is verified by comparing the strain measurement by the image analysis with the strain measurements by the conventional method based on the displacement meter. In our previous study, the validity of this method has been examined for uni-axial deformation, i.e., uni-axial tension and simple shear. In this report, three types of different deformation paths, i.e., the combined deformation of uni-axial tension and simple shear, the simple shear after uni-axial tension and the uni-axial tension after simple shear are examined in the range of large plastic deformation, and the principal values of stretch and these directions are obtained visually from the image measurements of the three line elements marked on the surface of the specimen.
