Abstract:
1. An image processing apparatus for forming an image by recording of each of a plurality of recording element arrays on a same area of a recording medium with use of a recording head group constructed by connecting a plurality of recording heads, each of which includes the plurality of recording element arrays configured to record a same color component, to one another in such a manner that the recording element arrays partially overlap in a direction in which the recording element arrays are arranged, the image processing apparatus comprising: a setting unit configured to set input image data to recording data of each of the recording element arrays; and a halftone processing unit configured to generate halftone image data to be recorded by each of the recording element arrays by performing halftone processing on the recording data of each of the recording element arrays, which is set by the setting unit, wherein the halftone image data is generated so that halftone image data pieces corresponding to at least a pair of recording element arrays located on a same recording head for recording on a same area and halftone image data pieces corresponding to at least a pair of recording element arrays located on different recording heads for recording on the same area are in an antiphase with each other in a part of a frequency band, and wherein halftone image data pieces corresponding to at least a pair of recording element arrays located on a same recording head are in an antiphase with each other in a wider frequency band than halftone image data pieces corresponding to at least a pair of recording element arrays located on different recording heads.
