摘要：
An image processing apparatus in which a density pattern is generated which corresponds to input image data. Growth direction of the density pattern is controlled by generating a density pattern in a prescribed direction, and generating a density pattern in a direction based on a random signal. As a result, when printing the image data based on the generated density patterns, there is no joining between adjacent pixels and a high-quality image is produced.
