Abstract
An image processing apparatus that converts input image data into halftone image data that a plurality of arranged nozzles ejecting ink can print and includes one or more hardware processors and one or more memories storing one or more programs configured to be executed by the one or more hardware processors, the one or more programs including instructions for correcting a pixel value of each pixel in the input image data in accordance with a characteristic of the nozzle and generating first halftone image data by performing halftone processing for a second frequency component whose frequency is lower than that of a first frequency component of frequency components corresponding to the corrected input image data. Here, the first halftone image data is data that is generated to be printed with first dots whose dot size causes adjacent dots to overlap.
