Abstract

PURPOSE: To improve a picture quality and a transmission efficiency by reading data suitably for original patterns.
CONSTITUTION: Data read in by scanner 1 is stored in analogue memory 2, and simultaneously, this data is subjected to sampling by sampling gate 3 and is converted to quarternaries by A/D converter 4; and if data is discriminated as the intermediate level by level decoder 5, it is counted by counter 6. After the completion of the scan of one-line components, the output is decoded by count decoder 7, and an analogue image is discriminated if data is over a prescribed value. Then, data stored in analogue memory 2 is outputted to plotter 10 by multiplexer 9. If data is discriminated as a digital picture, data in analogue memory 2 is inputted to plotter 10 through multiplexer 9.
