Abstract

An image processing method and apparatus for automatically rotating an image and a display unit, and an information storage medium storing image information. The apparatus including a photographing unit which generates image data and a rotation sensing unit which generates rotational information of a rotation state of the photographing unit. When an object is photographed, the rotation information of the image is obtained and stored together, and when the image is displayed, the rotation is analyzed and the image and display unit are automatically rotated. When an image including moving picture information is watched, an image always optimized to be horizontal without additional work by a user can be seen.
