  • Publication number: 20190028606
    Abstract: A technique capable of keeping image quality and speeding up a halftone process is provided. An image processing device performs the halftone process on image data in which a pixel has a pixel value conforming to a bit count N. Bits conforming to the bit count N include higher H bits (where H is an integer satisfying an inequality of 1?H<N) and lower L bits following the higher H bits (where L is an integer satisfying an inequality of 1?L?N?H). The image processing device includes a first halftone processing unit configured to generate dot data indicative of a formation state of a dot, with respect to a first pixel allowing a determination of a formation state of a dot, based on the higher H bits in the pixel value and higher H bits in a dither mask.
