For saving the capacity of pattern memory which stores characteristic information of the reference image patterns in an image-handling machine such as a seal verification device or a pattern recognition device, the characteristic information is composed of only some selected horizontal and vertical scan lines of the image pattern and represented by the ratio of the spacings between the pattern lines across the selected horizontal and vertical scan lines to the width and height of the pattern. Referring to the figure, each character or pattern may be represented by m horizontal scan lines and n vertical scan lines and characterized by only some selected horizontal and vertical scan lines of, for example, the Kanji character H1, H5, V2 and V3.
