ABSTRACT:
A method of forming a matrix image used in various devices with an image processing function.
In the image forming method, each image segment constituted by an m.times.n dot matrix is divided into at least one element, and each element is defined by a parallelogram on a basic matrix. The image segment is encoded according to characteristic features of the parallelogram. Data signals representing each image segment are stored in a set of at least one coded element in a memory. The dot patterns of the entire image are formed according to image segment display data. Even a complicated pattern can be smoothly and clearly formed. In addition, processing for obtaining an enlarged image or a rotated image can be simplified and performed with a small-capacity memory.
