Image processing method and apparatus

摘要

This invention provides an image processing method and apparatus. Two types of edge emphasis processing operations having different degrees of edge emphasis are performed for image data of a read original. When paper quality of the original instructed by an operation unit is recycle paper, the edge emphasis processing having a smaller degree of the two types of edge emphasis processing operations is selected. The selected (multi-value) image data is binary-converted, and the binary-converted image data is output, thereby obtaining good image quality with respect to the read original regardless of the paper quality of the read original.
