METHOD AND APPARATUS FOR DEPOSITING PARTIAL DOTS REPRESENTING MULTI-LEVEL GRAY LEVELS

摘要

The partial dot printing method and apparatus are disclosed for implementing a multi-level gray scale. Of dot printing method according to the present invention is the gradation of the image matrix corresponding to the multi-level image and a pixel matrix generating step of converting the received image sequence to receive a continuous image in the multi-level image composed of pixels in matrix having a plurality of gradation Based on, a dot output step of outputting a dot on the pixel. Dot output stage, the output stage of the dot to dot the output of the dot so as to have a gradation corresponding to the pixel dot region division step, and divided pieces of the multi-level image of the dot matrix, which is divided into regions of a predetermined number of pixels to be output includes. Multi-level image matrix generating step, based on the gradation level of the image of the number and configuration of the multi-level dot image matrix and the output stage of the dot, the period for setting the center point of the printed dot area of the center point setting step and the center point by starting from the latest point from a step of outputting a dot portion. Can easily output an image with a multi-level gray scale by the present invention.
