Abstract
A printing control device includes an input image data acquiring unit, a threshold acquiring unit, a determining unit, and a generating unit. The input image data acquiring unit acquires input image data. The input image data includes a plurality of input pixel data. Each input pixel data has an input value. The determining unit determines, for each input pixel data, a difference related value based on a difference between the input value and a threshold value corresponding to the input value. The generating unit generates print data by generating, for each input pixel data, output pixel data based on the difference related value. The output pixel data expresses density corresponding to the difference related value.
Claims14
A printing control device comprising:
- an input image data acquiring unit that acquires input image data, the input image data including a plurality of input pixel data, each input pixel data having an input value;
- a determining unit that determines, for each input pixel data, a difference related value based on a difference between the input value and a threshold value corresponding to the input value;
- and
- a generating unit that generates print data by generating, for each input pixel data, output pixel data based on the difference related value, the output pixel data expressing density corresponding to the difference related value.
