Abstract
An image forming apparatus includes: a hardware processor that quantizes each pixel with a dither pattern divided according to a resolution in a predetermined direction, and sets a recording amount of each pixel by adding up processing results of the quantization.
Claims10
An image forming apparatus comprising:
- a hardware processor that:
- acquires a selected recording resolution in a predetermined direction;
- divides, according to the selected recording resolution, a dither pattern having a spatial frequency characteristic designed for a resolution different from the selected recording resolution, to obtain a plurality of divided dither patterns having a spatial frequency characteristic matched to the selected recording resolution;
- quantizes each pixel with each of the plurality of divided dither patterns;
- and
- sets a recording amount of each pixel by adding up processing results of the quantization performed with each of the plurality of divided dither patterns.
