Abstract

PURPOSE:To make the picture processing automatically and quickly, by automatically picking up the threshold value for binary processing. CONSTITUTION:The digital contrast picture data picked up from the picture memory device 1 is calculated for the threshold value for the binary processing from the data in the threshold value decision device 2. The threshold value calculated in the threshold value decision device 2 is transferred to the threshold value processor 3. The threshold value processor 3 picks up the picture data from the picture memory device 1 again for binary processing, and the result (digital binary data) is stored in the graphic memory device 4.
