1. An image processing apparatus for generating an output image based upon inputted print data and delivering the output image to a prescribed recording device, comprising:

  • density setting means for setting a dark level of recording density;

    input means for inputting binary print data intended to be printed at a first resolution;

    resolution converting means for generating binary image data having a second resolution by splitting each pixel in image data, which is based upon the binary print data inputted by said input means, into a plurality of partial pixels and then applying a correction; and

    output means for outputting the binary image data converted by said resolution converting means to the prescribed recording device;

    said resolution converting means including;

    a plurality of arithmetic means for computing the state of each individual partial pixel at the second resolution, wherein computations performed by individual arithmetic means differ from one another; and

    selecting means for selecting one of said plurality of arithmetic means in dependence upon the dark level of recording density set by said density setting means.
