Abstract
PURPOSE:To detect a character image to have a faint part by selecting a threshold obtained in all scan areas and a threshold obtained in a local area and executing a binarization. CONSTITUTION:A value adding the maximum value and minimum value of a concentration value in all scan areas by an adder 5 is inputted to a selecting device 27. For the data of a distance converting value data memory 15 storing data in which the processing of a neighboring linking black point scanned by a distance converting circuit is executed and data storing the scanned data as they are, a similarity degree is obtained by a similarity operating circuit 30 in an address from a register 16 to divide a local area, the local area is obtained and outputted to a comparator 26. The sum of the maximum value and minimum value of the concentration in the obtained local area is given from an adder 18 to the selecting device 27. The selecting device 27, according to a compared result signal between the similarity degree from the circuit 30 and the prescribed similarity degree of a register 25 by the comparator 26, selects the concentration value from the adder 5 or the adder 18 and outputs it to a comparator 28 to a binarizing processing as the threshold of a binarizing level.
