Abstract

A method of making an image in a digital camera comprises capturing a digital image of a scene into which the camera user is to be inserted, and superimposing a symbol (subject locator) onto the scene image representing at least a part of a human subject. The subject locator is scaled to a desired size and moved to a desired position relative to the scene image. Next a digital image of the user is captured, and at least the part of the user image represented by the subject locator is extracted. The part of the user image represented by the subject locator is scaled (before or after extraction) to substantially the same size as the subject locator and inserted into the first image at the position of the subject locator.

Claims

1. A method of making an image in a digital camera, the method comprising:

displaying a preview image of a scene into which a camera user is to be inserted,

superimposing on the preview image a symbol (“

subject locator”

) representing at least a part of a human subject,

scaling the subject locator to a desired size and moving it to a desired position relative to the edges of the preview image,

detecting a camera user entering the scene displayed by the preview image,

scaling and panning the preview image to bring the part of the preview image represented by the camera user to substantially a same size and position as the subject locator, and

capturing a digital image of the scene.

2. The method claimed in claim 1, wherein the detecting comprises detecting a face or separating foreground and background, or both, within the preview image.

3. The method claimed in claim 2, wherein the detecting comprises detecting and tracking the face.

4. The method claimed in claim 1, wherein the camera forms part of a cell phone.

5. The method claimed in claim 1, wherein the preview and main digital images are captured through the same lens system.

6. The method claimed in claim 5, wherein the main digital image is captured using a self-timer.

7. The method claimed in claim 1, further comprising separating foreground and background for the preview image, and wherein the superimposing of the subject locator partly overlaps the foreground of the preview image, and the method further comprises selecting whether the user is to be inserted in front of or behind the foreground of the preview image.

8. The method claimed in claim 1, further comprising selecting a profile of the subject locator and determining the scaled part of the main digital image based on the profile of the subject locator.

9. The method claimed in claim 8, wherein the profile of the subject locator comprises head and shoulders, mid-shot or full length.

10. A digital camera including an optical system for acquiring digital images, a processor, and one or more processor-readable media having embodied therein processor-readable code for programming the processor to perform a method of making an image in a digital camera, the method comprising:

displaying a preview image of a scene into which a camera user is to be inserted,

superimposing on the preview image a symbol (“

subject locator”

) representing at least a part of a human subject,

scaling the subject locator to a desired size and moving it to a desired position relative to the edges of the preview image,

detecting a camera user entering the scene displayed by the preview image,

scaling and panning the preview image to bring the part of the preview image represented by the camera user to substantially a same size and position as the subject locator, and

capturing a digital image of the scene.

11. The camera claimed in claim 10, wherein the detecting comprises detecting a face or separating foreground and background, or both, within the preview image.

12. The camera claimed in claim 11, wherein the detecting comprises detecting and tracking the face.

13. The camera claimed in claim 10, wherein the camera forms part of a cell phone.

14. The camera claimed in claim 10, wherein the preview and main digital images are captured through the same lens system.

15. The camera claimed in claim 10, wherein the main digital image is captured using a self-timer.

16. The camera claimed in claim 10, the method further comprising separating foreground and background for the preview image, and wherein the superimposing of the subject locator partly overlaps the foreground of the preview image, and the method further comprises selecting whether the user is to be inserted in front of or behind the foreground of the preview image.

17. The camera claimed in claim 10, the method further comprising selecting a profile of the subject locator and determining the scaled part of the main digital image based on the profile of the subject locator.

18. The camera claimed in claim 17, wherein the profile of the subject locator comprises head and shoulders, mid-shot or full length.

19. One or more non-transitory processor-readable media having embodied therein processor readable code for programming the processor to perform a method of making an image in a digital camera, the method comprising:

displaying a preview image of a scene into which a camera user is to be inserted,

superimposing on the preview image a symbol (“

subject locator”

) representing at least a part of a human subject,

scaling the subject locator to a desired size and moving it to a desired position relative to the edges of the preview image,

detecting a camera user entering the scene displayed by the preview image,

scaling and panning the preview image to bring the part of the preview image represented by the camera user to substantially the same size and position as the subject locator, and

capturing a digital image of the scene.

20. The one or more non-transitory processor-readable media claimed in claim 19, wherein the detecting comprises detecting a face or separating foreground and background, or both, within the preview image.

21. The one or more non-transitory processor-readable media claimed in claim 19, wherein the detecting comprises detecting and tracking the face.

22. The one or more non-transitory processor-readable media claimed in claim 19, wherein the camera forms part of a cell phone.

23. The one or more non-transitory processor-readable media claimed in claim 19, wherein the preview and main digital images are captured through the same lens system.

24. The one or more non-transitory processor-readable media claimed in claim 19, wherein the main digital image is captured using a self-timer.

25. The one or more non-transitory processor-readable media claimed in claim 19, the method further comprising separating foreground and background for the preview image, and wherein the superimposing of the subject locator partly overlaps the foreground of the preview image, and the method further comprises selecting whether the user is to be inserted in front of or behind the foreground of the preview image.

26. The one or more non-transitory processor-readable media claimed in claim 19, the method further comprising selecting a profile of the subject locator and determining the scaled part of the main digital image based on the profile of the subject locator.

27. The one or more non-transitory processor-readable media claimed in claim 26, wherein the profile of the subject locator comprises head and shoulders, mid-shot or full length.
