Image processing method and apparatus and information storage medium storing image information
First Claim
1. An image processing method of displaying image information comprising:
- reading image data and rotation information including a rotation value of the image data included in a header of the image data;
determining a rotation angle of a display unit on which the image data is output using the rotation information;
rotating the display unit by the rotation angle; and
outputting the image data on the display unit,wherein the rotation angle is determined to be 0°
if the rotation value is less than or equal to a predetermined value.

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.
