PURPOSE:To improve transmission density and speed, by converting character information into character codes, and encoding the run length of graphic information with variable length code. CONSTITUTION:Kana (Japanese syllabary) are inputted from a keyboard 3, the character pattern corresponding to the characters is retrieved from a character pattern generator 5 and stored in a display memory 10. The content of the display memory 10 is displayed on a CRT display device 12 via a picture signal synthesizing circuit 11. Further, the picture pattern from a picture original input processor 7 is stored in the display memory 10 and displayed on the CRT display 12 with edited characters superimposingly. Further, the read picture pattern is converted into consecutive information of variable length code and stored in an information storage memory 16 after compression. |
