Abstract
The system and method speeds up the image composition process based upon the blurring function and the blurring function determination process; facilitates the confirmation and correction of the blurring function determination results; determines the relative position of image data and to enable the position match for the difficult image data that is corrected for the zoom ratio; and facilitates the confirmation and the correction of the image data relative positioning results.

A method of composing an image from a plurality of images, comprising:
- inputting a plurality of the images containing the same objects;
- displaying two images for a user input;
- determining a relative position between the two of the images based upon the user input according to a predetermined set of movements;
- determining at least one common in-focus area between the two images;
- determining an amount of difference in focus in the one common in-focus area between the two images;
- and
- composing an image from the two inputted images based upon the above determined amount of the difference in focus.
