In a method and apparatus for dividing an image area according to the present invention, when data of a quantized multi-gradational image are to be divided into regions according to a texture of the image, the quantized multi-gradational image data are divided into plural rectangular subareas and boundary areas. Each of the rectangular subareas and a boundary area in the periphery of the subarea are combined to form one set. The area dividing is conducted on each of the sets. In the area dividing, the subarea is subjected one time to a dividing process, and the boundary area is subjected two or more times to a dividing process.
