Claims

[Scope of utility model registration request]

In a digital copying machine that reads an image of a document, inputs it as image data, performs image transformation processing that involves a change in size, and then outputs it as an output image on copy paper, it is determined based on the size of the copy paper and the type of processing. The present invention is characterized by providing means for determining an inputtable range of the original document corresponding to an outputtable range on the copy paper from the amount of image deformation, and displaying the inputtable range based on the result. Image input device for digital copying machines.
