Image transforming system for facsimile store and forward exchange system

Abstract

PURPOSE: To enable use regardless of the upper size of a communicating party facsimile equipment by transforming an image corresponding to the paper size of the receiving facsimile when transmitting data to the receiving facsimile equipment. CONSTITUTION: A facsimile store and forward exchange device 1a reads image data from a magnetic disk 4a, and a facsimile store and forward exchange device 1b stores compressed image data in a magnetic disk 4b. In the case of outputting to a facsimile equipment 3b, the paper size of an original stored in the magnetic disk 4b is compared with the paper size of the facsimile equipment 3b and when the paper size of the facsimile equipment 3b is smaller, the image is reduced by an image transformation processing device 5b and outputted to the facsimile equipment 3b. A central processing unit 2b outputs the request of reduction to the image transformation processing device 5b, and the image transformation processing device 5b extends the dispatched image data to full dot data, afterwards, reduces these data, returns them to compressed image data and returns the data to the central processing unit 2b as a request source.
