Abstract
PURPOSE:To synthesize signals by real-time processing by processing the signal at a high speed by processing two kind of picture signals which are encoded by run length and unencoded hardware arithmetic. CONSTITUTION:The 1st picture signal read out of an original 1 is converted by a binary-coding circuits 6 into a binary signal, which is encoded by a run-length encoder 7 before being stored in one memory area of a memory 8 having three- layer hierarchy structure. The 2nd picture signal which is generated by a character generator 155 to show a character according to a character code is stored in the other memory area of the memory 8. The 1st and 2nd picture signals stored in the memory areas of the memeory 8 are transferred to a picture synthesizing circuit 9 under the control of a sequence controller 23. By the output of the memory area, the 1st picture signal is selected in some area other than a specific area, and the 2nd picture signal is selected in the specific area to process those two kind of picture signals through hardware arithmetic, thus synthesizing the signals by real-time processing.
