Abstract
A halftone image generating apparatus for use in a halftone image generating system for generating threshold value data corresponding to positions in a main scanning direction and a subsidiary scanning direction, comprising a threshold value data generating circuit for generating the threshold value data in a matrix pattern having a variable number of lines and rows, and for converting input picture image data having chromatic gradations into binary value data by comparing the input picture image data to the threshold value data, and a circuit for forming a scanning mesh dot image corresponding to the input picture image data.
