摘要： PURPOSE:To reduce the number of lines where notches are suppressed to half and generate transmit picture data while improving the holding quality of thin lines, by utilizing the holding quality of white thin lines by three-line logical processing and the statistical properties of a binary picture. CONSTITUTION:For example, data on lines A and B are stored in line memories 1 and 2 during the transmission of picture data, and a scan on a line C is in process. A comparator 7 reads specific patterns (a) and (b) out of an ROM 6 and compares them with the contents of a matrix register 5. When the contents of the register 5 are equal to the patterns (a) and (b), a clear setting signal STCLR is at H. Then, a clear pulse generating circuit 9 sends out a clear pulse CLRC. Then, the contents of memories 1 and 2 and register 5 are shifted. At this time, data overflowing the register 5 is inputted to a three-line logical processing circuit 8, whose processing result is sent out. On the other hand, when no picture data is sent out, the difference is only that the lines A-C are substituted by lines B-D. The transmission and nontransmission of those picture data are repeated alternately.
摘要翻译：目的：通过利用三线逻辑处理的白色细线的保持质量和二进制数的统计特性，将切口的数量减少到一半，生成发送图像数据同时提高细线的保持质量图片。构成：例如，在图像数据的发送期间，线A和B上的数据被存储在行存储器1和2中，并且线C上的扫描正在进行中。比较器7从ROM6读出特定的模式（a）和（b），并将其与矩阵寄存器5的内容进行比较。当寄存器5的内容等于模式（a）和（b）时，清除设置信号STCLR为H.然后，清除脉冲发生电路9发出清除脉冲CLRC。然后，存储器1和2和寄存器5的内容被移位。此时，将寄存器5溢出的数据输入到三行逻辑处理电路8，其处理结果被发送出去。另一方面，当没有发送图像数据时，不同之处仅在于线A-C被线B-D代替。这些图像数据的发送和不传输被交替地重复。
