PURPOSE:To accelerate processing speed by performing boundary trace by outputting the directional code of the next boundary point from the value of a nearby picture element and that of the directional code. CONSTITUTION:The boundary trace of an area is performed by using image memories 8a-8d in which image data are stored. At this time, the value in every direction of the nearby picture element and that of the directional code are inputted to a directional code generator 9, and the directional code of the next boundary point is outputted from the directional code generator 9. Then, the boundary of the area is traced following the directional code outputted from the directional code generator 9 by referring to the image memories 8a-8d in which the value of the nearby picture element is stored at every direction, which dispenses with reference to the image memory for plural number of times to detect the next boundary point. In such a way, it is possible to obtain an image processing device capable of efficiently tracing the boundary of the area, and operated at high processing speed. |
