  • Generating image region dot data based on corrected number of dots and determined arrangement priority
    Patent number: 10834288
    Abstract: In an embodiment of the present disclosure, an image processing apparatus for generating dot data, which defines whether or not a dot is arranged in each pixel, includes: a dot number derivation unit configured to derive a number of dots to be arranged in a predetermined region of image data; a determination unit configured to determine an arrangement priority of a pixel in which a dot is arranged, based on the pixel value of each pixel included in the predetermined region and a threshold value group in a threshold value matrix; a correction unit configured to correct the derived number of dots, in a case where the derived number of dots is smaller than a criterial number of dots; and a generation unit configured to generate the dot data, based on the corrected number of dots and the arrangement priority.
