<p>When recording on pixel regions is performed in M paths (where M is an integer not less than 2) by use of N recording element groups (where N is an integer not less than 2), density variations due to misalignment between recording positions of dots recorded in different paths are prevented even while a data processing load is reduced. First of all, respective pieces (24-1 and 24-2) of multi-valued image data, which correspond to the M paths, are generated from inputted image data. Then, pieces (26-1 and 26-2) of quantized data, which correspond to these M paths, are generated by quantizing the respective pieces of multi-valued image data, which correspond to the M paths. Thereafter, the respective pieces of quantized data, which correspond to the M paths, are divided into pieces of quantized data, which correspond to the N recording element groups and are complementary with one another. Thus, the pieces (28-1 to 28-4) of quantized data, which correspond to the respective M paths each using the N recording element groups, are acquired. This configuration makes it possible to prevent density variations due to misalignment between recording positions in the respective M paths, and, at the same time, to reduce a load for quantization processing since only a small number of pieces of data are subject to the quantization processing.</p> |
