Abstract:
1. An image processing apparatus that generates quantized data used for forming three or more types of dots having same hue which are different from one another in optical densities, said apparatus comprising: a generation unit configured to generate a plurality of multi-valued data for forming the three or more types of dots, based on data representing one color component; and a quantization unit configured to subject two multi-valued data corresponding to the two types of dots which are determined depending on a value of the color component data among the plurality of multi-valued data, to quantization with use of a table for generating quantized data, and to subject remaining multi-valued data other than the two multi-valued data to quantization without use of the table for generating quantized data, wherein the table is configured so that the two multi-valued data and quantized data corresponding to said two multi-valued data are associated with one another.
