Image processing system having variably controllable pixel density patterns |
摘要 |
On the basis of inputted multivalued image data, direction of growth is decided from a density pattern having a plurality of growth directions and a density pattern is caused to grow based upon the growth direction that has been decided. As a result, character images are formed sharply and high-quality half-tone images exhibiting reduced density irregularity can be produced.
