Abstract
The image processing method and related apparatus of the present invention contemplates the steps of setting a two-dimensional image filter to center around a subject picture element switching the coefficient of the two-dimensional image filter on a time-sharing basis during the time an image signal corresponding to one picture element is transferred, taking out a plurality of filter outputs relative to the image signal of the subject picture element, comparing the plurality of filter outputs with each other to identify which one of the character and half tone areas the subject picture element belongs to, and subjecting the image to individual process on an area basis. Accordingly, it is possible to distinguish between the character and half tone areas efficiently with a simple arrangement and simultaneously output an image of good quality.
