Patent Images
1. A method for providing information associated with a visual code, comprising:
- capturing an image using a digital camera in a mobile device, the image including a visual code and at least one non-code region associated with the visual code;
locating the visual code in the captured image;
retrieving information related to the at least one non-code region based at least in part on the visual code and an orientation of the mobile device relative to the visual code; and
displaying the retrieved information on the mobile device.

Abstract
Methods, media, and mobile devices for providing information associated with a visual code are provided. In some embodiments, methods for providing information associated with a visual code are provided, including capturing an image including a visual code and non-visual code regions using a mobile device; selecting a non-visual code region of the non-visual code regions based at least in part on the visual code and an orientation of the mobile device relative to the visual code; retrieving information associated with the selected non-visual code region; and displaying the retrieved information on the mobile device.

22. A method for providing information associated with a visual code, comprising:
-
capturing an image comprising a visual code and non-visual code regions using a mobile device; identifying regions in the image including the visual code and at least one non-visual code region; calculating at least one of orientations and shapes of at least one of the identified regions; locating the visual code based at least in part on the at least one of the orientations and shapes of the at least one of the identified regions; reading encoded bits in the visual code to produce a decoded value; determining an orientation of the mobile device relative to the visual code; selecting a non-visual code region of the at least one non-visual code region of the at least one identified regions based on the orientation of the mobile device relative to the visual code; retrieving information associated with the selected non-visual code region based at least in part on the decoded value; and displaying the retrieved information on the mobile device.

23. A mobile device for providing information associated with a visual code, comprising:
-
a screen; a digital camera; and a processor in communication with the screen and the digital camera, wherein the processor; captures an image comprising a visual code and non-visual code regions using the digital camera; identifies regions in the image including the visual code and at least one non-visual code region; calculates at least one of orientations and shapes of at least one of the identified regions; locates the visual code based at least in part on the at least one of the orientations and shapes of the at least one of the identified regions; reads encoded bits in the visual code to produce a decoded value; determines an orientation of the mobile device relative to the visual code; selects a non-visual code region of the at least one non-visual code region of the at least one identified regions based on the orientation of the mobile device relative to the visual code; retrieves information associated with the selected non-visual code region based at least in part on the decoded value; and displays the retrieved information on the mobile device.
