Title: Picture processing unit
Inventor: KOIKE KAZUMASA
IPC: H04N1/405
Filed: 1990-05-18
Abstract: PURPOSE:To decrease notch of a picture with simple processing and hardware constitution by replacing a picture element density of an edge part into a density larger in the white level or black level direction and binarizing the picture with error dispersion processing. CONSTITUTION:The processing unit consists of a picture read section 1, an A/D converter section 2, an edge picture element separation section 3, an edge picture element density correction section 4, an error dispersion processing section 5, and a picture output section 6. While picture elements not for the edge among multi-value picture information are converted into binary picture information by the error dispersion method as they are, the density of white level picture elements of the edge is corrected into a higher white level and the density of black level picture elements of the edge is corrected into a higher black level respectively and the result is converted into binary picture information by the error dispersion method. Thus, white/black level inversion of picture elements at the edge is reduced by simple processing and hardware constitution and the notch of the picture is decreased.
