Digital image outputting device, and image data handling device and method thereof

摘要

A digital image data and producing an image on a recording medium based on the image data is provided. The digital image outputting device detects the page-size of image data received. The image data is compressed and stored in an image memory. The stored image data is expanded within the image memory in a compressed state. The necessary capacity of the recording area is determined based on presumption of both the detected and the worst data-compressing rate. A recording area is reserved which matches the determined capacity. The image data compressed by the data compressor is stored in the reserved recording area.
