1. An image display apparatus for displaying an image on a predetermined display area, comprising:
- a first calculation unit adapted to calculate a first magnification for matching the size of said image in a horizontal direction with the size of said display area in a horizontal direction;
a second calculation unit adapted to calculate a second magnification for matching the size of said image in the vertical direction with the size of said display area in the vertical direction;
a first resizing unit adapted to obtain a first resized image by resizing said image using a magnification equal to or larger than the other magnification of said first magnification and said second magnification; and
a display control unit adapted to perform scrolling display on an area which cannot completely be contained in said display area in said first resized image.
