ABSTRACT:
An image output device includes a tone pattern generator 33 of an image processing portion 3 which, on the basis of image data representing border positions of a plurality of regions of an image divided according to density values thereof, generates a tone dot pattern corresponding to the density value of the region, a closed region assigning circuit 32 for assigning a closed region on an image memory corresponding to the resolution d of the respective closed region of the image, and a filling out processing circuit 34 writes the tone dot pattern in the assigned closed region as image data having the resolution d.
