Abstract

A method is described for producing a composite image that is viewable through lenticular lenses to create a special visual effect. The method includes the steps of storing a first source image and a second source image and selecting a pair of reference points in the first source image and corresponding reference points in the second source image. First and second intermediate images are created such that objects in the source images are better aligned, and the intermediate images are interlaced to produce the composite image.

Claims

1. A method for producing a composite image that is viewable through lenticular lenses to create a special visual effect, comprising the steps of:

storing a first source image and a second source image;

displaying simultaneously the first and second source images and selecting two reference points E1 and E2 in the first source image and corresponding reference points E3 and E4 in the second source image;

creating a first intermediate image including points E1 and E2 that is a version of the first source image and a second intermediate image including points E3 and E4 that is a version of the second source image, wherein the location of point E1 in the first intermediate image is the same as the location of point E3 in the second intermediate image, and the location of point E2 in the first intermediate image is the same as the location of point E4 in the second intermediate image; and

interlacing the first intermediate image and the second intermediate image to produce a composite image.

2. The method of claim 1, wherein the step of creating a first and a second intermediate image includes translating image data to align point E1 and point E3, performing a rotation of image data around point E1 or point E3, and performing a rescaling of the image data to align point E2 and point E4.

3. The method of claim 1, wherein the first intermediate image is the same as the first source image.

4. The method of claim 3, wherein the step of creating a second intermediate image includes translating image data to create a translated data array corresponding to the second source image, such that point E3 is at a location in the translated data array that is the same as the location of point E1 in the first intermediate image, rotating the translated image data around point E3 to create a rotated data array corresponding to the second source image, such that a line defined by points E3 and E4 in the rotated data array is at a location therein that is the same as the location of a line defined by points E1 and E2 in the first intermediate image, and rescaling the rotated data array to produce the second intermediate image corresponding to the second source image, such that a line segment defined by points E3 and E4 in the second intermediate image is the same size as a line segment defined by points E1 and E2 in the first intermediate image.

5. The method of claim 1, wherein the second intermediate image is the same as the second source image.

6. The method of claim 1, wherein the source images are displayed on a computer monitor.

7. The method of claim 1, wherein the source images include faces.

8. The method of claim 7, wherein the reference points are facial features.

9. The method of claim 1, wherein the selecting step is performed by a user.

10. The method of claim 1, wherein the selecting step is performed by a user, and the creating and interlacing steps are performed by a computer program.

19. The method of claim 1, further including the step of printing the composite image on one of a lenticular sheet and a paper sheet joinable with a lenticular sheet.

11. A method for producing a composite image that is viewable through lenticular lenses to create a special visual effect, comprising the steps of:

storing a first source image in the form of a first data file and a second source image in the form of a second data file;

displaying simultaneously the first and second source images and selecting two reference points E1 and E2 in the first source image and corresponding reference points E3 and E4 in the second source image;

creating an intermediate image that also includes points E3 and E4 and is a version of the second image, wherein the location of point E3 in the intermediate image is the same as the location of point E1 in the first source image and the location of point E4 in the intermediate image is the same as the location of point E2 in the first source image; and

interlacing the first source image and the intermediate image to produce a composite image.

12. The method of claim 11, wherein the source images are displayed on a computer screen.

13. The method of claim 11, wherein the source images include faces.

14. The method of claim 13, wherein the reference points are facial features.

15. The method of claim 11, wherein the selecting step is performed by a user.

16. The method of claim 11,wherein a user performs the selecting step, and a computer program performs the creating and interlacing steps.

17. The method of claim 11, wherein the interlaced image is in the form of an interlaced data file.

18. A method for producing an interlaced image viewable through lenticular lenses to create a special visual effect, comprising the steps of:

storing a first source image as a first data array and a second source image as a second data array in a memory of a computer;

viewing the first source image and the second source image simultaneously on a display of the computer and selecting two reference points E1 and E2 in the first image and reference points E3 and E4 in the second image, wherein point E3 corresponds to point E1 and point E4 corresponds to point E2;

processing the second data array to create an intermediate image as an intermediate data array that also includes points E3 and E4 and is a version of the second source image, wherein the processing includes the steps of aligning point E3 with point E1 of the first source image to create an aligned image, rotating and resizing the aligned image to produce the intermediate array wherein a line segment defined by points E1 and E2 in the first data array is the same size and orientation as a line segment defined by points E3 and E4 in the intermediate data array; and

interlacing the first data array and the intermediate data array to produce a composite image as an interlaced array.
