ABSTRACT:
In a scaling control device of an image processing apparatus, original image data stored in a storage section are enlarged n times by a scaling section, data are interpolated to the enlarged image data by an interpolating section, and the resulting image data are compressed to 1
by a compressing section. The processed image data are stored in a storage section within a storage region where the original image data were stored under the control of a storage control section. An expanding section retrieves the processed image data from the storage section and expands the same to an initially specified enlarged-scaling magnification for an output image. As a result, it has become possible to minimize an increase of a capacity of the storage section in response to an increase in image data, and thus, the resulting apparatus becomes less expensive.
