Image processing apparatus and image processing method

摘要

There is provided an image processing method that can output a high-quality image having high dispersing quality in the configuration for printing an image using a plurality of different kinds of dots. Therefore in the same region of a printing medium, binary data is generated such that a low frequency component of space frequency characteristics is suppressed with priority to a dot pattern of a combination in which a plurality of kinds of dots are relatively noticeable.

主权项

1. An image processing apparatus for printing an image on a printing medium with a plurality of relative movement between a print head capable of printing dots of a plurality of sizes on the printing medium and the printing medium comprising:
a binarization unit configured to generate binary data for printing each of the dots of the plurality of sizes with each of the plurality of relative movements, based upon multi-valued image data, wherein the binarization unit generates the binary data such that in the same region of the printing medium, a low frequency component of space frequency characteristics of a dot pattern obtained by accumulating dot patterns printed respectively by the plurality of relative movements in regard to a dot of a first size among the dots of the plurality of sizes is smaller than a low frequency component of space frequency characteristics of a dot pattern obtained by accumulating dot patterns printed respectively by the plurality of relative movements in regard to a dot of a second size among the dots of the plurality of sizes.
