An image reducing device comprises a simple-averaging device that calculates a simple average of data of pixels of each simple-averaging area of original image data to acquire a pixel of middle image data, and a weighted-averaging device that multiplies data of pixels of the middle image data that are adjacent to a pixel of reduced image data by weight coefficients according to positions of the pixel of the reduced image data and the pixels of the middle image data to acquire the pixel of the reduce image data. In this method, the weighted-averaging is performed after the number of pixels are reduced by the simple-averaging, and this can obtain the reduced image of high quality without overloading the software and hardware. In addition, the edging can be easily performed at the same time as the weighted-averaging.
