Abstract
A halftone image recording apparatus has a photoelectric converter for generating a density signal representing the density level of an image, a periodical or random signal generator for periodically or randomly generating level signals, an adder for adding the density signal and the level signals, a memory for storing the addition signal from the adder, a pattern generator for generating an image pattern, and an ink jet head or the like to record the image pattern. Pseudooutlines are eliminated without requiring an increase in the reading resolution and without imparing the resolution during recording. Input image data is compressed and a memory of smaller capacity can be used.
