1. An image processing apparatus comprising:
- an image input unit which inputs image data corresponding to a document image as an input document image;
a first variable scale-factor unit which varies the input document image by a desired scale factor;
a division unit which divides the input document image into one or more regions;
a scale-factor designating unit which designates scale factor of an image at one of the regions divided by the division unit to scale factor different from that of the first variable scale-factor unit;
a second variable scale-factor unit which varies the image at the one of the divided regions by the scale factor designated by the scale-factor designating unit; and
a synthesis unit which synthesizes the input document image varied in scale by the first variable scale-factor unit and the image varied in scale by the second variable scale-factor unit.

Abstract
One or more rectangular regions including image objects are extracted from input document image. The input document image is reduced by a desired scale factor, and the extracted rectangular regions are varied in scale by scale factors greater than the desired scale factor. The input document image varied in scale by the desired scale factor and the rectangular region images varied in scale are synthesized and outputted.

6. An image processing method comprising the steps of:
-
inputting image data corresponding to a document image as an input document image;
varying the input document image by a desired scale factor;
dividing the input document image into one or more regions;
designating scale a factor of an image at one of the divided regions to scale factor different from the desired scale factor;
varying the image at the one of the divided regions by the designated scale factor; and
synthesizing the input document image varied in scale by the desired scale factor and the image varied in scale by the designated scale factor. - View Dependent Claims (7, 8)

9. An image forming apparatus comprising:
-
an image reading unit which reads a document image, and which provides image data corresponding to the document image as an input document image;
a first variable scale-factor unit which varies the input document image provided from the image reading unit by a desired scale factor;
a division unit which divides the input document image into one or more regions;
a scale-factor designating unit which designates scale factor of an image at one of the regions divided by the division unit to scale factor different from that of the first variable scale-factor unit;
a second variable scale-factor unit which varies the image at the one of the divided regions by the scale factor designated by the scale-factor designating unit;
a synthesis unit which synthesizes the input document image varied in scale by the first variable scale-factor unit and the image varied in scale by the second variable-scale-factor unit; and
an image forming unit which forms an image corresponding to the image synthesized by the synthesis unit, on a paper. - View Dependent Claims (10)
