Abstract
A picture image scanning and reproducing method capable of operating a picture image processing unit at a constant system clock even when the data transferring speed for digital picture image signals obtained by scanning an original or the data transferring speed in a picture image recording unit is changed, as well as a system suitable for use in the practice of the above method. Signals can be processed at a constant throughput owing to the provision of frequency changing means respectively at both input and output sides of the picture image processing unit. A single system clock is input to each of various processing circuits, where the system clock is converted to a desired frequency so as to operate the corresponding processing circuit. Therefore, the present invention has materialized simplification of the circuit structure and reduction of the manufacturing cost.
