摘要:
In one or more implementations, a signal is received selecting a geographic location in an original image of a digital map for display on a display. The original image is distorted to give an appearance of a lens being applied to the digital map for display on the display, the appearance of the lens including a focal region that includes a magnification of the geographic location and a base region that surrounds the focal region.

A method for generating a presentation of a region-of-interest in an original image for display on a display screen, comprising: establishing a focal region for the region-of-interest at least partially surrounded by a shoulder region; creating a focal region image for the focal region by scaling the original image within the focal region by a focal region magnification; creating a shoulder region image for the shoulder region by scaling the original image within the shoulder region by a shoulder region magnification, the shoulder region magnification being less than the focal region magnification; and, overlaying the focal region image and the shoulder region image on the original image to thereby generate the presentation.

A method in a computer system for generating a presentation of a region-of-interest in an original image for display on a display screen, the original image being a collection of polygons having polygons defined by three or more shared edges joined at vertex points, the method 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 across which the magnification decreases, the focal and shoulder regions having respective perimeters; subdividing polygons in the collection of polygons proximate to at least one of the perimeters, as projected with the polygons onto a base plane, by inserting one or more additional vertex points and additional edges into the polygons to be subdivided; and, applying the lens to the original image to produce the presentation by displacing the vertex points onto the lens and perspectively projecting the displacing onto a view plane in a direction aligned with a viewpoint for the region-of-interest.

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.

A method for generating a presentation of a region-of-interest in an original image for display on a display surface, the method comprising: establishing a lens for the region-of-interest, the lens having a focal region with a magnification for the region-of-interest at least partially surrounded by a shoulder region across which the magnification varies to provide a continuous transition from the focal region to regions outside the lens; receiving a first signal for selecting the shoulder region; while receiving the first signal, receiving a second signal for selecting the focal region and for adjusting a position of the focal region relative to the shoulder region to define a degree and a direction of a folding of the focal region over the shoulder region for the lens; and, applying the lens to the original image to produce the presentation.

摘要:
In an implementation, an image is distorted for display on a display device to give an appearance of a lens being applied to the image. A brightness level of the appearance of the lens for display on the display device is adjusted such that the brightness level of the appearance of the lens differs from a brightness level of the portion of the image that surrounds the appearance of the lens.
