Abstract:
The present invention provides an image processing device which is capable of avoiding disappearance of print data such as thin lines by increasing probability in which an original image is stored even after resolution conversion processing is executed to a binary image. In order to achieve this, the present invention may leave the pixels in any of the two lines halftone-processed with same threshold value row after the resolution conversion in a given ratio.
