ABSTRACT:
An image processing apparatus comprises an extraction unit configured to extract areas having predetermined attributes from image data of a document; a calculation unit configured to calculate skew angles of the areas extracted by the extraction unit; a selection unit configured to select necessary elements by determining, as unnecessary elements, the areas having the calculated skew angles not less than a threshold and by determining, as the necessary element, the areas having the calculated skew angles less than the threshold; and a processing unit configured to apply image processing to the necessary elements selected by the selection unit.
