Device and method for expanding multilevel image
专利汇可以提供Device and method for expanding multilevel image专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a smooth conversion image by determining the density of a picture element to be converted from the inclination of the edge of an image to be converted. CONSTITUTION:When a converted picture element input means 111 supplies the density data of a prescribed converted picture element group positioned near the picture element to be converted, an image edge detecting means 113 detects the edge of an original image and its inclination from the coordinates of the picture element, the magnification of conversion and density data. A divided area deciding means 115 divides the area surrounded by the converted picture element group in accordance with the magnification of conversion so that the area ratio is 2 (n: positive number) on the basis of the inclination of the image edge and the array of picture elements and decides the position of the picture element to be converted. A digit moving means 117 moves the digit of respective density data of the picture element to be converted expressed by the binary method based upon the area ratio and a picture element density calculating means 119 calculates the density of the picture element to be converted. Consequently, the edge part of the original image can be smoothly expressed.，下面是Device and method for expanding multilevel image专利的具体信息内容。
