Abstract

PURPOSE: To reproduce a thinly darwn part by determining a slice level by detecting the maximum and minimum levels of thickness information.
CONSTITUTION: A pattern signal obtained by every scan on a picture is applied to shift register 10 and successively shifted, four by four bits, to shift registers 11W14. Every time it is shifted once, levels are extracted from registers 10W12 three times each and the mean value is calculated to obtain a center level. It is applied to shift register 16 and a level, extracted every time the input is shifted to shift registers 17W20 in sequence, is applied to 5×5 matrix part 35, which detects the maximum and minimum values of the black level to determine a slice level that corresponds to the value. This slice level signal is applied to binary-coding threshold-level determining circuit 38 and compared to a peak value output from n-scan peak detecting circuit 37 to output larger one. On the basis of this signal, the input signal is converted into a binary-coded slice pattern signal.
