Abstract
PURPOSE: To make it possible to create a compact picture data file and supply it to an information processing unit by extracting only picture data in an arbitrary area within a reading paper and compressing this data.
CONSTITUTION: The blue light and the red light for marking of the reflecton light from paper 1 where characters, patterns, etc., are recorded are inputted to photoelectric conversion elements 35 and 36 respectively, and the output of element is subjected to waveform shaping in 37 and 38 respectively. Each waveform-shaped output is inputted to detector circuit 4 to generate extracting signals corresponding to an area-specified pattern dependent upon marking, and the area specified by signals from element 35 is extracted by giving these extracting signals to gate circuit 5 and is supplied to compression circuit 6. Then, data only in the part specified by extracting signals is compressed and is outputted as digital signals.
