Abstract
An image processing apparatus includes a reader unit for reading original image data, a converting unit for converting the original image data to digital image data, a first magnification changing unit for magnifying/reducing the digital image data, an image data modification unit for modifying the magnification changed data, a second magnification changing unit for magnifying/reducing the modified data and a visualizing unit for visualizing an image on the basis of the second magnification changed data. According to the apparatus, the first magnifying/reducing is executed, and after the modification process, the second magnifying/reducing is executed. As a result, the function is improved in aspects of degrees of freedom of the modification operations.
