There is disclosed an image processing apparatus and a control method thereof in which input image data and generates a plurality of tile images, each including a substance region and overlap regions each of which overlaps with a part of each adjacent tile image, by dividing the input image data. The apparatus executes image processing separately on each of the plurality of the generated tile images, and when generating each tile image, converts a resolution of image data in the overlap regions such that the resolution of the image data in the overlap regions is smaller than a resolution of image data in the substance region.

Processing tile images including overlap regions

It is determined whether each of objects separated from a plurality of objects arranged in a single page is character object or not, and with respect to an object determined as a character object, a ratio of pixels configuring a character in the determined object to all pixels in said determined object is calculated. A character object in which the ratio crosses a predetermined reference value, when the plurality of objects in the single page are scaled and arranged in accordance with a size of a sheet set by a user, is arranged in a different page.

Image forming apparatus with adaptive automatic layout function

Object data representing an image object extracted from image data is stored. A display unit displays the image object or the contour of the image object in accordance with the display mode designated by a user.
