ABSTRACT:
An image processing apparatus for resizing image data by a determined desired magnification. The apparatus includes an image data inputting section for inputting the image data, a magnification determining section for determining a magnification based on the image size of the inputted image data and the print size, a magnification converting section for converting the determined desired magnification into a combination of a first reduction ratio including 100% magnification, an expansion ratio and a second reduction ratio including 100% magnification, a first image reducing section for reducing the image data by the first reduction ratio by using an averaging operation, an image expanding section for expanding the resultant reduced image data by the expansion ratio by using an interpolating operation, and a second image reducing section for reducing the resultant expanded image data by the second reduction ratio by using an averaging operation.
