Abstract

A system for play-back of a still image comprising an image generator for generating a panoramic image by stitching together a plurality of images; memory space allocated for storing the panaoramic image generated by the image generator; and motion playback device (MPB) coupled to the memory space by address and data lines. The MPB comprises an input for receiving parameters for generating addresses to read the image for simulating the panning motion is a video camera scanning the image represented by the panoramic image along at least a first direction. In an alternate embodiment, a method and computer readable medium corresponding to the above system is described.

Claims

1. A system for play-back of a series of still images comprising:

an image generator for generating a panoramic image by stitching together a plurality of still images which were previously captured with a still camera;

memory for storing the panoramic image generated by the image generator, the memory space being coupled to the image generator; and

a motion playback device coupled to the memory by address and data lines and comprising an input for receiving parameters for generating addresses to read from the memory and for simulating a panning motion of a video camera scanning the panoramic image along a first direction;

wherein the motion playback device generates a viewport with a given dimension for displaying a portion of the panoramic image therein;

whereby the displaying of the portion of the panoramic image in the viewport simulates the panning motion of the video camera panning the panoramic image along the first direction; and

wherein a simulated panning speed of the motion of the video camera is proportional to an offset added to a set of planar coordinate addresses of pixels to be displayed in the viewport corresponding to the first direction along which the motion of the video camera is simulated.

2. The system of claim 1 wherein the motion playback device is adapted to receive settings information for controlling the simulated panning speed of motion of the video camera.

3. The system of claim 1 wherein the motion playback device receives setting information comprising a frame frequency for simulating the video camera.

4. The system of claim 1 wherein the motion playback device is adapted to receive settings information comprising a raster structure for simulating the video camera.

5. The system of claim 1 wherein the motion playback device is adapted to receive settings information for controlling horizontal and vertical dimensions of the viewport.

6. The system of claim 1 wherein the motion playback device is adapted to receive settings information comprising horizontal and vertical dimensions of the panoramic image.

7. The system of claim 1 wherein the image generator comprises a perspective correction device comprising means for adapting the perspective of one of the images and a subsequent one of the images, and the motion playback device.

8. The system of claim 1 wherein the motion playback device is adapted to receive settings information comprising a image starting address for the panoramic image.

9. The system of claim 1 wherein the motion playback device is adapted to receive settings information comprising focal length of the optic used to take the images.

10. The system of claim 1 further comprising a digital still camera for taking the plurality of still images.

11. The system of claim 1 wherein the motion playback device comprises:

means for correcting the perspective of each of the images that are stitched to form the panoramic image; and

means for converting the perspective of the images into a plurality of perspectives simulating the panning motion of a video camera panning the scenes represented by the panoramic image.

12. A method for play-back of a panoramic image that is formed from a plurality of still images, the method comprising the steps of:

receiving a digital panoramic still image, which were previously captured with a still camera;

storing the digital panoramic still image;

scanning the image; and

playing the scanned image through a motion playback device which simulates a panning motion of a video camera acquiring the scene that is displayed along a first direction;

wherein the motion playback device generates a viewport with a given dimension for displaying a portion of the panoramic image therein;

whereby the displaying of the portion of the panoramic image in the viewport simulates the panning motion of the video camera panning the panoramic image along the first direction; and

wherein a simulated panning speed of the motion of the video camera is proportional to an offset added to a set of planar coordinate addresses of pixels to be displayed in the viewport corresponding to the first direction along which the motion of the video camera is simulated.

13. The method of claim 12 further comprising the step of:

correcting the perspective of an overlap region between a first of the images and a preview of a second of the images.

14. The method of claim 13 further comprising the step of:

generating an overlay for warping the frame of a previous of the images into the coordinate frame of the current one of the images.

15. The method of claim 13 further comprising the step of:

recording a plurality of images from a plurality of substantially contiguous perspectives.

16. A computer readable medium containing programming instructions for play-back of a panoramic image that is formed from a plurality of still images, the programming instructions comprising:

receiving a digital panoramic still image, which were previously captured with a still camera;

storing the digital panoramic still image;

scanning the image; and

playing the scanned image through a motion playback device which simulates a panning motion of a video camera acquiring the scene that is displayed along a first direction;

wherein the motion playback device generates a viewport with a given dimension for displaying a portion of the panoramic image therein;

whereby the displaying of the portion of the panoramic image in the viewport simulates the panning motion of the video camera panning the panoramic image along the first direction; and

wherein a simulated panning speed of the motion of the video camera is proportional to an offset added to a set of planar coordinate addresses of pixels to be displayed in the viewport corresponding to the first direction along which the motion of the video camera is simulated.

17. The computer readable medium of claim 16, further comprising the instruction of:

correcting the perspective of an overlap region between a first of the images and a preview of a second of the images.

18. The computer readable medium of claim 16, further comprising the instruction of:

generating an overlay for warping the frame of a previous of the images into the coordinate frame of the current one of the images.

19. The computer readable medium of claim 16, further comprising the instruction of:

recording a plurality of images from a plurality of substantially contiguous perspectives.
