System and method for horizon correction within images
First Claim
1. A method for automatic detection and correction of image orientation errors comprising the steps of:
- receiving a digital representation of an image;
identifying at least one vertical or horizontal objects within said image;
determining an orientation error of at least one of said identified vertical or horizontal objects;
rotating said digital representation of said identified image in a manner to reduce said orientation error; and
displaying a corrected digital image.

Abstract
The present invention includes a system and method for the correction of user induced inadvertent orientation errors in captured digital images before the digital image is saved to a storage media or memory. A system of the present invention checks a user-selectable input to determine if the orientation correction has been enabled, enables a tilt determining mechanism which senses orientation errors when the feature is enabled, corrects the orientation errors in the viewed image, displays a corrected digital image to the user and allows the user to store a digital representation of the corrected image into a memory. The method of the present invention includes receiving a digital representation of an image, identifying vertical or horizontal lines contained within the image, determining an orientation error, rotating the digital representation of the image to reduce the orientation error and displaying a corrected digital image.

9. An image orientation correction system comprising:
-
a user-selectable input device;
a tilt determining mechanism configured to sense orientation errors of received images;
a processor configured to respond to said user-selectable input device and to send said orientation errors of an image for modifying said image to remove said orientation errors; and
;
a display configured to display a digital image as modified by said processor. - View Dependent Claims (10, 11, 12, 13, 14, 15, 17, 18, 19, 20)

16. A camera comprising:
-
an image sensor;
a display connected to display an image captured by said image sensor;
an orientation sensor identifying an orientation of said image sensor with respect to said image captured by said image sensor; and
an image processor responsive to said orientation sensor for performing a rotation operation on said image captured by said image sensor so as to provide corrected image data reducing a misalignment of said image.
