Abstract

An image-creation method includes capturing an image as digital data, locating an area of interest of the captured image, extracting, from the digital data, at least some data corresponding to the located area of interest, digitally magnifying the extracted at least some data to yield digitally magnified data, and combining the digitally magnified data with at least some of the digital data of the captured image to yield combined data.

Claims

1. An image-creation method comprising:

capturing an image as digital data;

locating an area of interest of the captured image;

extracting, from the digital data, at least some data corresponding to the located area of interest;

digitally magnifying the extracted at least some data corresponding to the located area of interest to yield a magnified area-of-interest image; and

combining the digitally magnified extracted data with at least some of the digital data of the captured image to yield data representing a modified image comprising the magnified area-of-interest image and at least a portion of the captured image; and

compressing the data representing the modified image wherein the combining step results in the magnified area-of-interest image being located in an area of low interest of an image represented by the combined data.

2. The image-creation method of claim 1, further comprising buffering the digital data.

3. The image-creation method of claim 2, further comprising retrieving the captured data from the buffer.

4. The image-creation method of claim 1, wherein the locating step is performed before the capturing step.

5. The image-creation method of claim 1, further comprising identifying data corresponding to the located area of interest.

6. The image-creation method of claim 1, wherein the extracting step comprises extracting the data corresponding to the located area of interest.

7. The image-creation method of claim 1, wherein the extracting step comprises copying the at least some data corresponding to the located area of interest and not modifying the data corresponding to the located area of interest as present in the captured image.

8. The image-creation method of claim 1, further comprising identifying an area of low interest of the image.

9. The image-creation method of claim 8, wherein the combining step results in the magnified area-of-interest image being located in the area of low interest.

10. The image-creation method of claim 1, further comprising using the combined data to display the modified image.

11. The image-creation method of claim 1, further comprising:

repeating the recited steps a plurality of times; and

saving modified video data formed therefrom.

12. The image-creation method of claim 1, wherein, in the modified image, a portion of the captured image is replaced by the magnified area-of-interest image.

13. An article of manufacture for image creation, the article of manufacture comprising:

at least one computer readable medium;

processor instructions contained on the at least one computer readable medium, the processor instructions configured to be readable from the at least one computer readable medium by at least one processor and thereby cause the at least one processor to operate as to perform the following steps;

capturing an image as digital data;

locating an area of interest of the captured image;

extracting, from the digital data, at least some data corresponding to the located area of interest;

digitally magnifying the extracted at least some data corresponding to the located area of interest to yield a magnified area-of-interest image;

combining the digitally magnified extracted data with at least some of the digital data of the captured image to yield data representing a modified image comprising the magnified area-of-interest image and at least a portion of the captured image; and

compressing the data representing the modified image wherein the combining step results in the magnified area-of-interest image being located in an area of low interest of an image represented by the combined data.

14. The article of manufacture of claim 13, wherein the processor instructions are configured to cause the at least one processor to operate as to perform the following step:

buffering the digital data.

15. The article of manufacture of claim 14, wherein the processor instructions are configured to cause the at least one processor to operate as to perform the following step:

retrieving the captured data from the buffer.

16. The article of manufacture of claim 13, wherein the locating step is performed before the capturing step.

17. The article of manufacture of claim 13, wherein the processor instructions are configured to cause the at least one processor to operate as to perform the following step:

identifying data corresponding to the located area of interest.

18. The article of manufacture of claim 13, wherein the extracting step comprises extracting the data corresponding to the located area of interest.

19. The article of manufacture of claim 13, wherein the extracting step comprises copying the at least some data corresponding to the located area of interest and not modifying the data corresponding to the located area of interest as present in the captured image.

20. The article of manufacture of claim 13, further comprising identifying an area of low interest of the image.

21. The article of manufacture of claim 20, wherein the combining step results in the magnified area-of-interest image being located in the area of low interest.

22. The article of manufacture of claim 13, wherein the processor instructions are configured to cause the at least one processor to operate as to perform the following step:

using the combined data to display the modified image.

23. The article of manufacture of claim 13, wherein the processor instructions are configured to cause the at least one processor to operate as to perform the following steps:

repeating the recited steps a plurality of times; and

saving modified video data formed therefrom.

24. The article of manufacture of claim 13, wherein, in the modified image, a portion of the captured image is replaced by the magnified area-of-interest image.
