Abstract

A method comprises selecting a first center point for a first portion of an image, copying the first portion, centered about the first center point, to a buffer; and inverting the copied first portion about a first edge of said portion.

Claims

1. A method, comprising:

selecting a first center point for a first portion of an image;

copying said first portion, centered about said first center point, to a buffer; and

inverting said copied first portion about a first edge of said portion.

2. The method of claim 1 further comprising inverting said copied first and inverted portions about a second edge of said copied first and inverted portions.

3. The method of claim 1 further comprising inverting said copied first and inverted portions about a second edge of said copied first and inverted portions, said second edge being orthogonal to said first edge.

4. The method of claim 1 further comprising inverting said copied first and inverted portions about a second edge of said copied first and inverted portions, said second edge not being orthogonal to said first edge.

5. The method of claim 1 wherein, in response to user input, performing said selecting, copying and inverting on a larger version of said image.

6. The method of claim 1 further comprising:

copying a second portion of a larger version of said image to a second buffer, said second portion centered about a second center point corresponding to the first center point; and

inverting said second portion about a third edge of said copied second portion.

7. The method of claim 6 further comprising inverting said copied second portion and said inverted second portion about a fourth edge of said copied second portion and said inverted second portion.

8. The method of claim 1 further comprising offsetting said copied first portion before inverting said copied first portion.

9. An apparatus, comprising:

a display;

an input control;

storage on which an image is stored;

logic coupled to said display, said input control and said storage, said logic permits a first center point associated with a first portion of said image to be selected via the input control, copies said first portion to a buffer, and invert said copied first portion about a first edge of said portion.

10. The apparatus of claim 9 further comprising inverting said copied first and inverted portions about a second edge of said copied first and inverted portions.

11. The apparatus of claim 9 further comprising inverting said copied first and inverted portions about a second edge of said copied first and inverted portions, said second edge being orthogonal to said first edge.

12. The apparatus of claim 9 further comprising inverting said copied first and inverted portions about a second edge of said copied first and inverted portions, said second edge not being orthogonal to said first edge.

13. The apparatus of claim 9 wherein, in response to user input, performing said selecting, copying and inverting on a larger version of said image.

14. The apparatus of claim 9 further comprising:

copying a second portion of a larger version of said image to a corner of a second buffer, said second portion centered about a second center point corresponding to the first center point; and

inverting said second portion about a third edge of said copied second portion.

15. The apparatus of claim 14 wherein said logic inverts said copied second portion and said inverted second portion about a fourth edge of said copied second portion and said inverted second portion.

16. The apparatus of claim 9 wherein said logic offsets said copied first portion before inverting said copied first portion.

17. The apparatus of claim 9 wherein said apparatus comprises a camera.

18. A storage medium containing software that, when executed by a processor, causes the processor to:

select a first center point for a first portion of an image;

copy said first portion, centered about said first center point, to a buffer; and

invert said copied first portion about a first edge of said portion to generate a first reflected image.

19. The storage medium of claim 18 wherein said software further causes the processor to invert said copied first and inverted portions about a second edge of said copied first and inverted portions.

20. The storage medium of claim 18 wherein said software further causes the processor to generate a second reflected image, corresponding to said first reflected image, of a larger version of said image.
