Method of color separation scanning

摘要

A method of color separation scanning an input picture includes the steps pre-scanning the input picture at a lower resolution for providing a lower resolution image on an output device, indicating desired geometric manipulations to be performed on the input picture, and scanning the input picture at a higher resolution in accordance with the desired geometric manipulations to provide higher resolution color separations of the input picture. After the pre-scan, a point of the lower resolution image may be selected and a second pre-scan conducted at higher resolution over a region around the selected point to permit evaluation and modification (if desired) of sharpness prior to final scanning.
