Abstract

Disclosed is a panoramic sequence guide that can be used to guide a user in composing and capturing images to be used to create a composite panoramic image. In use, the guide tracks a viewed scene, determines the proper position of a composition guide relative to the viewed scene, and displays a composition guide on a live-view screen that provides an indication of what portion of the viewed scene is to be captured. The displayed composition guide is fixed to the viewed scene such that the guide moves with the viewed scene in the screen.

Claims

1. A method for guiding a user in composing and capturing images to be used to create a composite panoramic image, comprising:

tracking a viewed scene;

determining the proper position of a composition guide relative to the viewed scene; and

displaying a composition guide on a live-view screen that provides an indication of what portion of the viewed scene is to be captured, the composition guide being fixed to the viewed scene such that the guide moves with the viewed scene in the screen.

2. The method of claim 1, wherein tracking a viewed scene comprises positioning a marker over a viewed scene, recording coordinates of its position, and performing correlation computations to determine the change in direction and distance of a presently viewed scene verses a previously viewed scene.

3. The method of claim 1, wherein determining the proper position of a composition guide comprises determining the location of a scene that was previously captured and determining the position for the guide relative to that scene.

4. The method of claim 1, wherein determining the proper position of a composition guide comprises determining the location of a scene that is to be captured and determining the position for the guide relative to that scene.

5. The method of claim 1, wherein displaying a composition guide comprises displaying a guide that is indicative of a previously captured scene.

6. The method of claim 1, wherein displaying a composition guide comprises displaying a guide that is indicative of a scene that is to be captured.

7. The method of claim 1, wherein displaying a composition guide comprises displaying a rectangle indicative of one of a previously captured image and an image that is to be captured.

8. The method of claim 7, wherein displaying a composition guide further comprises displaying the guide such that it is offset relative to the previously captured image or image to be captured, so as to facilitate overlapping of images.

9. The method of claim 1, further comprising receiving selection of first and second endpoints and determining a virtual panoramic image to be captured that extends between the endpoints.

10. The method of claim 9, wherein displaying a composition guide comprises displaying a composition guide that is aligned with and forms part of the virtual panoramic image.

11. A system for guiding a user in composing and capturing images to be used to create a composite panoramic image, comprising:

a dynamic tracking system that is configured to track a viewed scene such that objects in the scene are identified and their movement tracked relative to a live-view screen; and

a panoramic sequence guide system that is configured to receive information from the tracking system, determine the proper placement of a composition guide relative to the viewed scene, and display a composition guide on the live-view screen to provide a user with an indication of what portion of the viewed scene is to be captured next in a sequence of scenes in order to capture images that can be used to create the panoramic image, the composition guide being fixed relative to the viewed scene in the live-view screen such that the guide moves with the viewed scene.

12. The system of claim 11, wherein the dynamic tracking system is configured to position a marker over a viewed scene, record coordinates of its position, and perform correlation computations to determine the change in direction and distance of a presently viewed scene verses a previously viewed scene.

13. The system of claim 11, wherein the panoramic sequence guide system is configured to determine the proper position of the composition guide relative to a previously captured image.

14. The system of claim 11, wherein the panoramic sequence guide system is configured to determine the proper position of a composition guide relative to a scene to be captured.

15. The system of claim 11, wherein the panoramic sequence guide system is configured to display a rectangle that is indicative of an image that was or is to be captured.

16. The system of claim 11, wherein the panoramic sequence guide system is configured to display a composition guide that is offset relative to the image that was or is to be captured.

17. The system of claim 11, wherein the panoramic sequence guide system is further configured to receive selection of first and second endpoints indicative of first and second ends of a panoramic scene and to determine a panoramic image that is to be captured.

18. A guidance system stored on a computer-readable medium, comprising:

logic configured to track objects of a viewed scene by determining their coordinates; and

logic configured to display at least one composition guide on a live-view screen that is fixed to the viewed scene so as to move across the screen along with the viewed scene, the at least one composition guide providing an indication of what portion of the viewed scene is to be captured next in order to create a panoramic image.

19. The system of claim 18, wherein the logic configured to display is configured to display a composition guide indicative of a previously captured image.

20. The system of claim 18, wherein logic configured to display is configured to display a composition guide indicative of a scene that is to be captured next.

21. A panoramic image guidance system, comprising:

means for tracking a scene viewable in a live-view screen; and

means for displaying a composition guide on the live-view screen, the guide being associated with the viewable scene so as to move in unison with the scene relative to the screen, the composition guide providing an indication of what portion of the scene is to be captured.

22. The system of claim 21, wherein the means for display is configured to display a rectangle indicative of an image that has been or is to be captured.

23. A camera, comprising:

a live-view screen;

a processor; and

memory comprising a dynamic tracking system and a panoramic sequence guide system, the dynamic tracking system being capable of tracking a scene viewable in the live-view screen so that movement of objects in the scene relative to the screen can be identified, the panoramic sequence guide system being capable of displaying a composition guide on the live-view screen that provides a user with an indication of what portion of the viewed scene to capture, the composition guide being fixed relative to the viewable scene such that the guide moves in unison with the scene.

24. The camera of claim 23, wherein the live-view screen comprises a screen within a camera viewfinder.

25. The camera of claim 23, wherein the live-view screen comprises a back-panel display of the camera.

26. The camera of claim 23, wherein the panoramic sequence guide system is configured to display a composition guide that is indicative of a previously captured image.

27. The camera of claim 23, wherein the panoramic sequence guide system is configured to display a composition guide that is indicative of an image that is to be captured.
