Dynamic width adjustment for detail-in-context lenses
First Claim
1. A method for reducing occlusion in a presentation of a region-of-interest of an original image, the presentation generated by distorting the original image to produce a lens having a focal region for the region-of-interest at least partially surrounded by a shoulder region defined by a shoulder drop-of function, comprising:
- scaling the focal region; and
, for an input point in the shoulder region, determining a width for the shoulder region from a distance between a projection point for the input point to the focal region and an intersection point on a perimeter of the lens of a line constructed through the input point, the projection point, and the intersection point, to thereby reduce occlusion of the shoulder region by the focal region.

Abstract
A method for reducing occlusion in a presentation of a region-of-interest of an original image, the presentation generated by distorting the original image to produce a lens having a focal region for the region-of-interest at least partially surrounded by a shoulder region defined by a shoulder drop-of function, comprising: scaling the focal region; and, for an input point in the shoulder region, determining a width for the shoulder region from a distance between a projection point for the input point to the focal region and an intersection point on a perimeter of the lens of a line constructed through the input point, the projection point, and the intersection point, to thereby reduce occlusion of the shoulder region by the focal region.

14. A system for reducing occlusion in a presentation of a region-of-interest of an original image, the presentation generated by distorting the original image to produce a lens having a focal region for the region-of-interest at least partially surrounded by a shoulder region defined by a shoulder drop-of function, comprising:
-
a processor coupled to memory, a display, and an input device and adapted for;
scaling the focal region; and
,for a point in the shoulder region, determining a width for the shoulder region from a distance between a projection point for the point to the focal region and an intersection point on a perimeter of the lens of a line constructed through the point, the projection point, and the intersection point, to thereby reduce occlusion of the shoulder region by the focal region.

15. A computer program product having a computer readable medium tangibly embodying computer executable code for directing a data processing system to reduce occlusion in a presentation of a region-of-interest of an original image, the presentation generated by distorting the original image to produce a lens having a focal region for the region-of-interest surrounding by a shoulder region defined by a shoulder drop-of function, comprising:
-
code for scaling the focal region; and
,code for, for a point in the shoulder region, determining a width for the shoulder region from a distance between a projection point for the point to the focal region and an intersection point on a perimeter of the lens of a line constructed through the point, the projection point, and the intersection point, to thereby reduce occlusion of the shoulder region by the focal region.

16. An article having a computer readable modulated carrier signal medium being usable over a network, the computer readable modulated carrier signal medium having embedded means for directing a data processing system to reduce occlusion in a presentation of a region-of-interest of an original image, the presentation generated by distorting the original image to produce a lens having a focal region for the region-of-interest at least partially surrounded by a shoulder region defined by a shoulder drop-of function, comprising:
-
means in the medium for scaling the focal region; and
,means in the medium for, for a point in the shoulder region, determining a width for the shoulder region from a distance between a projection point for the point to the focal region and an intersection point on a perimeter of the lens of a line constructed through the point, the projection point, and the intersection point, to thereby reduce occlusion of the shoulder region by the focal region.
