A problem of mismatch in pixel resolution between a front-end device, at one relatively low pixel resolution, and an output device such as a non-impact printer or a display at a higher pixel resolution is overcome by providing for grey level enhancement of low pixel resolution binary image data to minimize jaggies in a printed or displayed image, and then increasing the pixel resolution of the grey level enhanced image data to match that of the output device.

[ What is claimed is:] [1.] An image processing apparatus comprising:first means for outputting first binary image data at a relatively low pixel resolution:second means for generating grey level enhanced binary image data at the low pixel resolution wherein certain binary pixels are converted to grey level pixels at the low resolution; andthird means for increasing the pixel resolution of the grey level enhanced binary image data to match the resolution of an output device wherein the grey level enhanced binary image data now includes grey level pixels at a higher resolution than the grey level pixels at the low pixel resolution.
