Method and apparatus for using motion information and image data to correct blurred images
A method and apparatus for use in a digital imaging device for correcting image blur in digital images by combining plurality of images. The plurality of images that are combined include a main subject that can be selected by user input or automatically by the digital imaging device. Blur correction can be performed to make the main subject blur-free while the rest of the image is blurred. All of the image may be made blur-free or the main subject can be made blur-free at the expense of the rest of the image. Result is a blur corrected image that is recorded in a memory.
1. A method comprising:
displaying an image in a viewfinder;
designating, by a processor, a main subject in the image in the viewfinder;
capturing a plurality of photographic images in a recording medium, wherein the plurality of photographic images include the designated main subject;
combining the plurality of photographic images selectively to generate a corrected image, wherein a first part of the corrected image is generated by combining a first set of images from among the plurality of images, a second part of the corrected image is generated by combining a second set of images from among the plurality of images, and at least one image in the first set of images is not included in the second set of images; and
storing the corrected image in a memory.
2. The method of claim 1 , wherein designating the main subject is based on image segmentation or pattern recognition techniques.
3. The method of claim 1 , further comprising indicating the designated main subject in the viewfinder.
4. The method of claim 1 , wherein the combining includes shifting the plurality of photographic images combined such that the designated main subject is aligned in a same location in each of the plurality of photographic images combined.
5. The method of claim 1 , wherein the combining comprises determining pixel values for only a portion of the main subject.
6. The method of claim 1 , wherein combining the plurality of photographic images to generate a corrected image is performed by combining sequential images.
7. The method of claim 1 , wherein the corrected image is displayed in the viewfinder.
8. A method comprising:
displaying an image in a viewfinder;
receiving user input, by the viewfinder, designating a main subject in the image;
capturing a plurality of photographic images at a recording medium, wherein the plurality of photographic images include the designated main subject;
combining the plurality of photographic images selectively to generate a corrected image, wherein a first part of the corrected image is generated by combining a first set of images from among the plurality of images, a second part of the corrected image is generated by combining a second set of images from among the plurality of images, and at least one image in the first set of images is not included in the second set of images; and
storing the corrected image in a memory.
9. The method of claim 8 , wherein the viewfinder receives the user input based on a selection of an indicator in the viewfinder.
10. The method of claim 8 , wherein the processor indicates the main subject by an indicator in the viewfinder based on the received user input.
11. The method of claim 8 , wherein the combining comprises shifting the plurality of images combined such that the main subject is aligned in a same location in the plurality of images combined.
12. The method of claim 8 , wherein the combining comprises determining pixel values for only a portion of the main subject.
13. The method of claim 8 , wherein combining the plurality of photographic images to generate a corrected image is performed by combining sequential images.
14. The method of claim 8 , wherein the corrected image is displayed in the viewfinder.
15. An apparatus comprising:
a viewfinder configured to display an image;
a processor configured to designate a main subject in the image in the viewfinder;
a recording medium configured to capture a plurality of photographic images, wherein the plurality of images includes the designated main subject;
the processor further configured to selectively combine the plurality of photographic images to generate a corrected image, wherein the processor:
combines a first set of images from among the plurality of images to generate a first part of the corrected image, combines a second set of images from among the plurality of images to generate a second part of the corrected image, and at least one image in the first set of images is not included in the second set of images; and
a memory configured to store the corrected image.
16. The apparatus of claim 15 , wherein the processor is configured to designate the main subject using image segmentation or pattern recognition techniques.
17. The apparatus of claim 15 , wherein the processor is further configured to indicate the main subject by an indicator in the viewfinder.
18. The apparatus of claim 15 , wherein the processor is configured to designate more than one designated main subject in the plurality of photographic images.
19. The apparatus of claim 15 , wherein the processor is configured to shift the plurality of photographic images combined such that the main subject is aligned in a same location in the plurality of photographic images combined.
20. The apparatus of claim 15 , wherein the combined plurality of photographic images determines pixel values for only a portion of the main subject.
21. The apparatus of claim 15 , wherein the combined plurality of photographic images are sequential images.
22. The apparatus of claim 15 , wherein the viewfinder is further configured to display the corrected image.
23. Apparatus including
a viewfinder configured to display an image;
a processor configured to receive user input that designates a main subject in the image in the viewfinder;
a recording medium configured to capture a plurality of photographic images, wherein the plurality of photographic images includes the designated main subject;
