Abstract

Generating a photograph with a digital camera may include capturing a first image of a scene with a first zoom setting and capturing a second image of the scene with a second zoom setting, where the second zoom setting corresponds to higher magnification than the first zoom setting. The second image may be stitched into the first image in place of a removed portion of the first image that corresponds to a portion of the scene represented by the second image. The result is the photograph, which has a region corresponding to image data of the second image and a region corresponding to image data of the first image.

Claims

1. A method of generating a photograph with a digital camera, comprising:

capturing a first image of a scene with a first zoom setting;

capturing a second image of the scene with a second zoom setting, the second zoom setting corresponding to higher magnification than the first zoom setting;

up-sampling the first image to generate an interim image; and

stitching the second image into the interim image in place of a removed portion of the interim image that corresponds to a portion of the scene represented by the second image such that the stitched image is the photograph, the photograph having higher perceptual quality in a region corresponding to image data of the second image than in a region corresponding to image data of the first image.

2. The method of claim 1, wherein the first image corresponds to a field of view of the camera that is composed by a user of the camera.

3. The method of claim 1, wherein up-sampling of the first image includes filtering image data of the first image.

4. The method of claim 1, wherein the first image and the second image have substantially the same center spot with respect to the scene.

5. The method of claim 1, wherein a center spot of the second image is shifted with respect to a center spot of the first image.

6. The method of claim 5, further comprising using pattern recognition to identify an object in the scene and the center spot of the second image is centered on the object.

7. The method of claim 6, wherein the recognized object is a face.

8. The method of claim 1, wherein the first and the second images are captured in rapid succession to minimize changes in the scene between capturing the first image and capturing the second image.

9. The method of claim 1, further comprising:

capturing at least one additional image, where each additional image is captured with a zoom setting different than the first zoom setting; and

combining each additional image with the first and second images so that the photograph has quality regions that correspond to image data from each image.

10. The method of claim 9, wherein each image has substantially the same center spot with respect to the scene.

11. The method of claim 10, wherein the zoom setting associated with each image is different than every other zoom setting.

12. The method of claim 9, wherein at least two of the images have corresponding center spots that differ from the rest of the images.

13. A camera assembly for generating a digital photograph, comprising:

a sensor for capturing image data;

imaging optics for focusing light from a scene onto the sensor, the imaging optics being adjustable to change a zoom setting of the camera assembly; and

a controller that controls the sensor and the imaging optics to capture a first image of a scene with a first zoom setting and a second image of the scene with a second zoom setting, the second zoom setting corresponding to higher magnification than the first zoom setting, wherein the controller;

up-samples the first image to generate an interim image; and

stitches the second image into the interim image in place of a removed portion of the interim image that corresponds to a portion of the scene represented by the second image such that the stitched image is the photograph, the photograph having higher perceptual quality in a region corresponding to image data of the second image than in a region corresponding to image data of the first image.

14. The camera assembly of claim 13, wherein the first image corresponds to a field of view of the camera assembly that is composed by a user of the camera assembly.

15. The camera assembly of claim 13, wherein up-sampling of the first image includes filtering image data of the first image

16. The camera assembly of claim 13, wherein the first image and the second image have substantially the same center spot with respect to the scene.

17. The camera assembly of claim 13, wherein a center spot of the second image is shifted with respect to a center spot of the first image.

18. The camera assembly of claim 17, wherein pattern recognition is used to identify an object in the scene and the center spot of the second image is centered on the object.

19. The camera assembly of claim 13, wherein the first and the second images are captured in rapid succession to minimize changes in the scene between capturing the first image and capturing the second image.

20. The camera assembly of claim 13, wherein the controller controls the sensor to capture at least one additional image, where each additional image is captured with a zoom setting different than the first zoom setting and the controller combines each additional image with the first and second images so that the photograph has quality regions that correspond to image data from each image.

21. The camera assembly of claim 13, wherein the camera assembly forms part of a mobile telephone that establishes a call over a network.

22. A method of generating a photograph with a digital camera, comprising:

capturing a first image of a scene with a first zoom setting;

capturing a second image of the scene with a second zoom setting, the second zoom setting corresponding to higher magnification than the first zoom setting;

down-sampling the second image to generate an interim image; and

stitching the interim image into the first image in place of a removed portion of the first image that corresponds to a portion of the scene represented by the interim image such that the stitched image is the photograph.

23. The method of claim 22, wherein the first image corresponds to a field of view of the camera that is composed by a user of the camera.

24. The method of claim 22, wherein down-sampling of the second image includes filtering image data of the second image.

25. The method of claim 22, further comprising:

capturing at least one additional image, where each additional image is captured with a zoom setting different than the first zoom setting; and

combining each additional image with the first and second images so that the photograph has regions that correspond to image data from each image.
