Abstract

PURPOSE:To obtain an excellent binarized image by detecting the state of a noticed picture element from corrected brightness data on the picture element itself, the contrast to peripheral picture elements, etc., and binarizing the noticed picture element. CONSTITUTION:Brightness data on a specific picture element and brightness data on picture elements in a predetermined specific area are used to generate 1st reference data, and a decision part 4 corrects the brightness data on the specific picture element according to the reference data to generate corrected brightness data. Further, the state of the specific picture element is detected from the corrected brightness data on the specific picture element and corrected brightness data on the picture elements in the specific area where the brightness data is corrected to generate 2nd reference data for binarization and a decision part 7 classifies the brightness data on the specific picture element by one level or the other level according to the 2nd reference data. Consequently, when an original where various stages coexist is read, the entire original surface is binarized and when various originals are read in one operation mode by a reader, etc., all original images are binarized excellently.
