Method And System For Stabilization And Reframing
A method and apparatus for dynamically maintaining a horizontal framing of a video. The system permits the user to freely rotate the device while filming, while visualizing the 5 final output in an overly on the device viewfinder or screen during shooting. The resulting recording is subsequently corrected to maintain a single orientation with a stable horizon. The system and method is operative display an overly over a captured representation of the captured video wherein the overlay indicates a modified image with respect to said orientation.
1 . A method of saving image data comprising the steps of:
receiving data representing a first image having a first orientation;
receiving data representing a second orientation indicating a device vertical orientation with respect to gravity;
reorienting said first image such that said second orientation becomes a vertical orientation of said first image to generate a reoriented image; and
saving said reoriented image.
2 . The method of claim 1 further comprising the steps displaying said first image and displaying an indicator indicating said second orientation.
3 . The method of claim 2 wherein said indicator is a graphic representative of an aspect ratio and said second orientation, wherein said indicator is overlaid over said first image in a manner representative of said reoriented image.
4 . The method of claim 3 wherein said aspect ratio changes in response to said second orientation.
5 . The method of claim 1 wherein said first image is a frame of a video.
6 . An apparatus comprising;
an image sensor for capturing an image data having a first orientation;
a rotational sensor for determine a rotational value;
a processor for determining a second orientation in response to said rotational value and for reorienting said image data in response to said second orientation to generate a reoriented image; and
storing said reoriented image.
7 . The apparatus of claim 6 further comprising a display for displaying said image and displaying an indicator indicating said second orientation.
8 . The apparatus of claim 7 wherein said indicator is a graphic representative of an aspect ratio and said second orientation, wherein said indicator is overlaid over said image in a manner representative of said reoriented image.
9 . The apparatus of claim 8 wherein said aspect ratio changes in response to said second orientation.
10 . The apparatus of claim 5 wherein said image is a frame of a video
11 . A method comprising the steps of:
Initializing a capture mode;
receiving a data representing an image;
receiving data representing a rotational position;
deactivating said capture mode;
rotating said image in response to said rotational position to generate a rotated image; and
storing said rotated image.
12 . The method of claim 11 further comprising the steps displaying said image and displaying an indicator indicating said rotational position.
13 . The method of claim 12 wherein said indicator is a graphic representative of an aspect ratio and said rotational position, wherein said indicator is overlaid over said image in a manner representative of said rotated image.
14 . The method of claim 13 wherein said aspect ratio changes in response to said rotational position.
15 . The method of claim 11 wherein said image is a frame of a video.
16 . A method of processing a video stream comprising the steps of:
initializing a video capture mode;
receiving a first data representing a video stream;
displaying a representation of said video stream;
receiving a second data representing an aspect ratio;
receiving a third data representing a rotational position; and
overlaying a graphic representative of said aspect ratio and said rotational position over said representation of said video stream.
17 . The method of claim 16 wherein said aspect ratio changes in response to said rotational position.
