Cameras, other imaging devices, and methods having non-uniform image remapping using a small data-set of distortion vectors
View Patent ↗A camera has a body and an electronic capture unit mounted in the body. The electronic capture unit selectively captures and stores a scene image as a representational electronic image having a first array of pixels. A control system is mounted in the body. The control system provides a remapped electronic image having a second array of pixels. A memory unit is disposed in the body. The memory unit stores a data-set defining an non-uniform mapping between a plurality of primary input coordinates mappable on said first array of pixels and plurality of primary output coordinates mappable on said second array of pixels. The control system uses the data-set to remap the pixels of the input electronic image to provide the remapped electronic image.
1. A digital memory containing a plurality of different modification files for modifying a captured electronic image, each of the modification files comprising:
(a) a template including an opening; and
(b) processing control information which instructs a processor to form an output image by:
(i) generating a background image showing a portion of the captured electronic image,
(ii) applying the template over less than all of the background image;
(iii) generating a modified version of a section of the portion of the captured electronic image; and,
(iv) overlaying the opening with the modified version of the electronic image.
2. The digital memory of claim 1 , wherein the template includes a drawing instrument and wherein the modified version of the electronic image appears to have been hand drawn using the drawing instrument.
3. The digital memory of claim 2 , wherein the modified version of the electronic image has a cartoon effect.
4. The digital memory of claim 2 , wherein the modified version of the electronic image appears to have been drawn with a pencil.
5. The digital memory of claim 2 , wherein the modified version of the electronic image shows an outline image.
6. The digital memory of claim 1 , wherein each of the modification files further comprises data representing a distortion map.
7. The digital memory of claim 6 , wherein the data representing the distortion map defines a plurality of primary coordinate pairs, each said primary coordinate pair having an input coordinate associated with the captured electronic image and an output coordinate associated with the output image.
8. The digital memory of claim 7 , wherein the output coordinates of the primary coordinate pairs are arranged in a two-dimensional grid superimposed over at least a portion of the output image.
9. The digital memory of claim 8 , wherein each said primary coordinate pair has an input coordinate associated with the captured electronic image and a secondary coordinate associated with the output image.
10. The digital memory of claim 1 , wherein each of the modification files further comprises user interface information.
11. The digital memory of claim 10 , wherein the user interface information provides instructions to assist a user in capturing the captured digital image.
12. A computer-readable storage medium having a modification file for modifying a captured electronic image, comprising:
(a) a template including an opening; and
(b) processing control information which instructs a processor to form an output image by
(i) generating a background image showing a portion of the captured electronic image,
(ii) applying the template over less than all of the background image;
(iii) generating a modified version of a section of the portion of the captured electronic image; and,
(iv) overlaying the opening with the modified version of the electronic image.
13. The computer-readable storage medium of claim 12 , wherein the template includes a drawing instrument and wherein the modified version of the electronic image appears to have been hand drawn using the drawing instrument.
14. The computer-readable storage medium of claim 13 , wherein the modified version of the electronic image has a cartoon-like appearance.
15. The computer-readable storage medium of claim 13 , wherein the modified version of the electronic image appears to have been drawn with a pencil.
16. The computer-readable storage medium of claim 13 , wherein the modified version of the electronic image shows an outline image.
17. The computer-readable storage medium of claim 12 , wherein each of the modification files further comprises data representing the distortion map.
18. A method for modifying a captured electronic image, comprising:
(a) providing a modification file, the modification file including
(i) a template including an opening; and
(ii) processing control information;
(b) communicating the modification file over a network to a processor, and;
(c) using the processor and the modification file to form an output image by:
(i) generating a background image showing a portion of the captured electronic image,
(ii) applying the template over less than all of the background image;
(iii) generating a modified version of a section of the portion of the captured electronic image; and,
(iv) overlaying the opening with the modified version of the electronic image.
19. The method of claim 18 , further comprising printing the output image.
20. The method of claim 19 , wherein the captured electronic image is captured using a scanner.
