<p>An image processing apparatus configured to perform a halftone processing on input image data using a plurality of threshold value matrixes, includes a determination means configured to, using a threshold value matrix according to an input value expressing a target pixel in the input image data, determine an output value of the target pixel by comparing the input value with a threshold value in the threshold value matrix. Each of the plurality of threshold value matrixes is used for a different input value and has a size smaller than the input image data, and a size of at least one threshold value matrix from among the plurality of threshold value matrixes is determined according to a dot pattern expressing a corresponding input value.</p> |
