Abstract

The picture scanning and recording method of this invention permits the simplification of the manner of designation and input for the processing of picture pattern regions and line picture regions and the simplification of the processing circuit. The original picture is classified into plural types of regions, e.g., picture pattern regions, border tint regions, line picture regions, line picture tint regions or into a plurality of picture pattern regions of the same type. The preference of overlapped areas of the thus-classified regions are ranked. Based on such ranking, a picture image signal corresponding to the region having the highest ranking is selected in each of such overlapped areas.
