Graphical user interfaces and occlusion prevention for fisheye lenses with line segment foci
View Patent ↗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.
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.
