Abstract:
1. An image processing apparatus, comprising: a scaling ratio obtaining mechanism configured to obtain information of a scaling ratio of image data of an original image scanned by scaling the original image in a sub-scanning direction; a normalizing mechanism configured to normalize magnified image data to its substantially original size when the scaling ratio obtained by the scaling ratio obtaining mechanism is a magnification ratio; a first detecting mechanism configured to detect if specific information is included in the image data normalized by the normalizing mechanism; a second detecting mechanism configured to store a plurality of items of specific information each having a plurality of sizes respectively corresponding to a plurality of scaling ratios, and when the scaling ratio obtained by the scaling ratio obtaining mechanism is a reduction ratio, the second mechanism selects one of the plurality of items of specific information as selected specific information, and to detect if specific information is included in the image data of the original image by comparing the selected specific information with specific information extracted from the image data of the original image; and a processing mechanism configured to subject the image data to specific processing when one of the first and second detecting mechanisms detects that the specific information is included in the image data.
