Abstract

PURPOSE:To simplify the preprocessing of picture processing of a character, a graphic, etc., by executing fine-line conversion and smoothing with good quality by real time. CONSTITUTION:A shift register 20 accumulates information as to a picture element. An output controller 21 operates for fetching a corresponding signal as necessary, and for instance, is constituted of a gate controlling circuit, etc. provided on a prescribed stage of the shift register. An OR circuit 22 takes OR of picture elements S8-S11 through the output controller 21. After that, an operation processor 26 decides whether the picture element density of a remarkable picture element S0 should be changed or not, in accordance with an output of each device 22-25, and a threshold level provided in advance by setting automatically or manually from the outside, through the operating device 23, the AND circuit 24 and the operating device 25.
