Filed: 1985-08-14
Abstract: PURPOSE:To attain a satisfactory reproduction by deciding a threshold for making a multi-value by using a local characteristic quantity and a general characteristic quantity after the local characteristic quantity of a picture is scaled by the general characteristic quantity. CONSTITUTION:For instance, one scanning line is divided into N. In such a case, the number of picture elements in one unit area which is divided is about 16-picture element. The picture element data in the unit area is made binary by a prescribed reference value, converted into the data of '0', '1', the number of black picture elements, for instance, the number of '0's is counted and used for the binarization of the next corresponding area as the number black picture elements of the next scanning line. In a binary processing of a read picture signal, a threshold is decided by using both characteristics of a general characteristic quantity and a local characteristic quantity, thereby a line picture is made binary mainly by the local characteristic quantity and a gradation picture is made binary mainly by the general characteristic quantity.
