Abstract

A digital image forming apparatus which includes an image reading part for optically reading an original and photoelectrically converting an input image signal into a two-level image data carrying character images and graphic images, a first storage part for storing the two-level image data, a second storage part for storing an output image data to be outputted, a character cutting part for taking out individually the character images from the two-level image data to define a size of each of the character images and an array of black pixels within the character images, a character line extraction part for extracting a character line data from the second data based on the size of each of the character images and the array of black pixels within the character images, a character alignment part for correcting the character images to have the same size and the same distance therebetween and aligning the set of lines of characters along the character alignment direction so that the corrected character images and the aligned lines are defined in the output image data, and an output part for outputting a copy in which the output image data is reproduced.
