Abstract:
An image processing apparatus configured to convert input image data into halftone image data by halftone-processing the input image data includes a prediction unit configured to predict a density of a pixel of interest, which is achieved when the halftone image data is printed, based on a group of halftone-processed pixels neighboring the pixel of interest according to a prediction method determined according to a halftone-processed pixel value of the pixel of interest, and a control unit configured to control the halftone processing according to the density predicted by the prediction unit.
