Image realignment apparatus and a method thereof
First Claim
1. A method of automatically rotating images, the method comprising the steps of:
- a loading step, for loading an image;
a detecting step, for detecting at least one image feature from the image;
a judging step, for judging whether the image feature is facing upwards; and
a rotating step, for rotating the image until the image feature is facing upwards.

Abstract
An image realignment apparatus and a method thereof are disclosed. The method includes judging whether an image feature, such as the facial feature in an image, is facing upwards by using a feature identification algorithm, wherein the image and the feature identification algorithm are stored in an image acquisition apparatus or a computer. Moreover, the method can automatically realign an image in order to obtain a correct display of the image, if the image feature is not facing upwards. Furthermore, the method firstly judges the image features and then rotates the image, or firstly rotates the image and then judges whether the image features are facing upwards. Whereby, the rotating step and the judging step are repeated until the image features are facing upwards so as to display the image correctly.
