Abstract

A method for generating a presentation of a region-of-interest in an original image for display on a display screen, comprising: establishing a lens for the region-of-interest, the lens having a magnified focal region for the region-of-interest at least partially surrounded by a shoulder region having diminishing magnification, the focal region having a perimeter defined by a radius r from a line segment; receiving one or more signals to adjust at least one of the radius r and a length len of the line segment to thereby adjust the perimeter; and, applying the lens to the original image to produce the presentation.

Claims

1. A method comprising:

applying a lens to an image, wherein the lens includes;

an extent of the lens,

a focal region having a magnification and a perimeter shaped according to a radius extending from a plurality of line segments, wherein one of the plurality of line segments has a non-zero angle with respect to another of the plurality of line segments, and

a shoulder region having a width between the focal region and the extent of the lens, wherein the shoulder region provides context for the focal region with respect to a portion of the image outside of the lens by preserving visibility of information surrounding the focal region.

2. The method of claim 1, further comprising:

determining at least one of;

a maximum value for the radius based at least on a present value of the magnification of the focal region, or

a minimum value for the width of the shoulder region based at least on the present value of the magnification of the focal region.

3. The method of claim 1, wherein each of the plurality of line segments is adjoined to a different one of the plurality of line segments.

4. The method of claim 1, wherein each of the plurality of line segments comprises at least one handle.

5. The method of claim 1, further comprising automatically constraining the focal region to fit a feature in the image.

6. The method of claim 1, further comprising automatically constraining the plurality of line segments to fit a feature in the image.

7. The method of claim 1, further comprising:

automatically recognizing a pattern in the image; and

at least one of;

automatically constraining the focal region to fit the pattern, or

automatically constraining the plurality of line segments to fit the pattern.

8. An apparatus comprising:

one or more processors together with one or more memories configured to;

apply a lens to an image, wherein the lens includes;

an extent of the lens,

a focal region having a magnification and a perimeter shaped according to a radius extending from a plurality of line segments, wherein one of the plurality of line segments has a non-zero angle with respect to another of the plurality of line segments, and

a shoulder region having a width between the focal region and the extent of the lens, wherein the shoulder region provides context for the focal region with respect to a portion of the image outside of the lens by preserving visibility of information surrounding the focal region.

9. The apparatus of claim 8, wherein the one or more processors together with the one or more memories are further configured to:

determine at least one of;

a maximum value for the radius based at least on a present value of the magnification of the focal region, or

a minimum value for the width of the shoulder region based at least on the present value of the magnification of the focal region.

10. The apparatus of claim 8, wherein each of the plurality of line segments is adjoined to a different one of the plurality of line segments.

11. The apparatus of claim 8, wherein each of the plurality of line segments comprises at least one handle.

12. The apparatus of claim 8, wherein the one or more processors together with the one or more memories are further configured to automatically constrain the focal region to fit a feature in the image.

13. The apparatus of claim 8, wherein the one or more processors together with the one or more memories are further configured to automatically constrain the plurality of line segments to fit a feature in the image.

14. At least one computer-readable storage device including a set of instructions for execution on one or more processors, wherein the set of instructions comprises:

applying instructions for applying a lens to an image, wherein the lens includes;

an extent of the lens,

a focal region having a magnification and a perimeter shaped according to a radius extending from a plurality of line segments, wherein one of the plurality of line segments has a non-zero angle with respect to another of the plurality of line segments, and

a shoulder region having a width between the focal region and the extent of the lens, wherein the shoulder region provides context for the focal region with respect to a portion of the image outside of the lens by preserving visibility of information surrounding the focal region.

15. The at least one computer-readable storage device of claim 14, wherein the set of instructions further comprises:

determination instructions for determining at least one of;

a maximum value for the radius based at least on a present value of the magnification of the focal region, or

a minimum value for the width of the shoulder region based at least on the present value of the magnification of the focal region.

16. The at least one computer-readable storage device of claim 14, wherein each of the plurality of line segments is adjoined to a different one of the plurality of line segments.

17. The at least one computer-readable storage device of claim 14, wherein each of the plurality of line segments comprises at least one handle.

18. The at least one computer-readable storage device of claim 14, wherein the set of instructions further comprises constraining instructions for automatically constraining the focal region to fit a feature in the image.

19. The at least one computer-readable storage device of claim 14, wherein the set of instructions further comprises constraining instructions for automatically constraining the plurality of line segments to fit a feature in the image.

20. The at least one computer-readable storage device of claim 14, wherein the set of instructions further comprises:

recognition instructions for automatically recognizing a pattern in the image; and

at least one of;

constraining instructions for automatically constraining the focal region to fit the pattern, or

constraining instructions for automatically constraining the plurality of line segments to fit the pattern.
