Title: Binarization system for picture
Inventor: MIYAZAWA HIDEYUKI
IPC: H04N1/403
Filed: 1986-06-20
Abstract: PURPOSE:To perform the binarization processing with the picture information having satisfactory reproducibility of thin lines, by changing the threshold level for binarizing the present picture elements in response to the density level of the preceding picture element. CONSTITUTION:A circuit consisting of an arithmetic amplifier A2, a transistor T, a capacitor C and an arithmetic amplifier A3 forms a sample holding circuit which protects the potential at a point (b) in response to a sample pulse signal SP and delays it by an amount equal to a single picture element. An arithmetic amplifier A4 serves as a differential amplifier which secures the difference between the potential of a point (c) and the threshold level set at a point (a). The signal of a point (d) at the output side is obtained by adding the signal of the point (c) to the fixed threshold level of the point (a). Then the signal of the point (d) varies in accordance with the density level of the preceding picture element. Thus it is possible to obtain the binarized output apporoximate to the conventional one undergone the MTF correction.
