ABSTRACT:
An image processing apparatus is provided, including division means for dividing input image data into a plurality of areas. Enlargement/reduction means are provided for enlarging/reducing image data. First calculation means calculate a first image size as a sum of results from enlargement/reduction at first to i-th areas enlarged/reduced by the enlargement/reduction means at a designated enlargement/reduction ratio. Second calculation means calculate a second image size as a result from the enlargement/reduction at an image comprising the first to i-th areas at the designated enlargement/reduction ratio. Determination means determine an enlargement/reduction ratio of enlargement/reduction to be performed on the image comprising the first to i-th areas, based on the first image size and the second image size.
