Abstract
Abstract A high speed screening technique is disclosed which can be used to enlarge an image, or when combined with a halftone screen, can be used for high speed screening of stored images. A microcompiler generates customized program code responsive to an input enlargement ratio. The customized program code then performs halftone screening on the input image for the specified desired enlargement ratio. In general, for each different enlargement ratio, a different customized program code is generated. Thus, a parameter of the screening process, the enlargement ratio, which is an input to the microcompiler, is not an input during the run time of the customized program code, thereby permitting the customized program code to run faster since an input parameter has been removed and built into the code itself.
