ABSTRACT:
A high definition image generating system for an image processing apparatus for forming an image by converting multi-level data into dot impact output data of font patterns. The system comprises a block forming circuit for averaging multi-level data by a (2.times.2) block, an edge-direction detecting circuit for detecting an edge direction to output an edge-direction detection signal, an edge detecting circuit for detecting an edge to output an edge detection signal, and a switching circuit for switching a font pattern to be outputted to another pattern according to the edge detection signal and the edge-direction detection signal.
