Abstract

A video recording that includes rotation around a central point within a desired range of motion is used to generate a set of frames that is cropped by use of a centering reference and a cropping template registered to each frame by using the centering reference in each of the frames. The centering reference is an interocular distance of the photographic subject (which may be a live person or a mannequin) so that a vertical centerline established at a midpoint of the interocular distance is centered laterally by the cropping template. The images obtained can be displayed in a portable computer device to give an illusion of viewing a photographic subject as a solid 3-D object on the screen and additional product images can be merged to give the further illusion that the subject is wearing the product.

Claims

1. A method, comprising:

obtaining a video recording of a photographic subject that includes rotation around a central point within a desired range of motion;

creating a set of frames from the video recording by editing the video recording to select the set of frames within a preselected range of camera angles within the desired range of motion from the video recording;

cropping each frame in the set of frames to generate a set of cropped frames; and

storing the set of cropped frames in a computer-readable medium;

wherein each frame is cropped by using a centering reference of the photographic subject and a cropping template registered to each of said frames by using the centering reference in each of said frames.

2. The method of claim 1, wherein the centering reference is an interocular distance of the photographic subject so that a vertical centerline established at a midpoint of the interocular distance is centered laterally by the cropping template.

3. The method of claim 2, wherein the photographic subject is a mannequin.

4. The method of claim 2, further comprising the steps of:

using a sensor to measure rotation around a point of a screen of a portable computing device; and

displaying multiple images from the computer-readable medium on the screen in response to an input from the sensor so that a displayed image shown from the computer-readable medium on the screen moves in correspondence with the screen to give an illusion of viewing a photographic subject as a solid 3-D object on the screen.

5. The method of claim 4, wherein the photographic subject in each frame of the set of cropped frames is aligned in a vertical position, a lateral position and a longitudinal position at a preselected image plane.

6. The method of claim 5, wherein the vertical centerline of each of the multiple images from the computer-readable medium is displayed at the center of the screen.

7. The method of claim 2, wherein the cropping template crops each of the set of frames to a desired ratio and resizes the image.

8. The method of claim 7, wherein the cropping template is sized by choosing substantially the largest size possible without going outside an original video area for any of the set of frames.

9. The method of claim 2, further comprising:

selecting a set of product images of a product photographic subject;

merging a plurality of the set of product images with a plurality of the set of cropped frames to create a set of merged images;

using a sensor to measure rotation around a point of a screen of a portable computing device; and

displaying multiple images from the set of merged images on the screen in response to an input from the sensor so that a displayed image shown on the screen moves in correspondence with the screen to give an illusion of viewing a photographic subject as a solid 3-D object on the screen;

wherein the product in each of the set of product images is aligned in a vertical position, a lateral position and a longitudinal position at a preselected product image plane so that a product vertical centerline established at a midpoint of the product is centered laterally and the product is registered with the photographic image to give an illusion that each of the images of the set of merged images is an actual image of the photographic subject wearing the product.

10. The method of claim 9, wherein the set of product images is obtained by photographing the product on a mannequin.

11. The method of claim 10, wherein the product is being worn on a mannequin head of the mannequin.

12. The method of claim 10, wherein the product in each image of the set of product images is aligned by the product vertical centerline established at a second midpoint of a second interocular distance of the mannequin.

13. The method of claim 12, wherein the product and the photographic subject are registered by aligning the vertical centerline with the product vertical centerline.

14. The method of claim 11, wherein the product and the photographic subject are registered by aligning the vertical centerline with the product vertical centerline.

15. The method of claim 1, wherein the cropping template crops each of the set of frames to a desired ratio and resizes the image.
