An image processing device includes a storage unit, a processing unit, and a memory. The storage unit stores a dither matrix. The memory has instructions stored thereon that, when executed by the processing unit, cause the processing unit to function as: an acquiring unit that is configured to acquire an image including a plurality of pixels, each pixel having a color value; an updating unit that is configured to update a color value of at least one pixel by adding a random number to the color value; and a thresholding unit that is configured to convert the updated color value into a binary value by using the dither matrix. |
