Method for context-preserving magnification of digital image regions
DC
First Claim
1. A method of digital image magnification in a graphical user interface, the method comprising:
- selecting for magnification a selected region of an original image in the graphical user interface; and
superimposing on the original image a floating plane region in the graphical user interface containing a magnified image of the selected region, wherein the floating plane region has an area larger than an area of the selected region and smaller than an area of the original image, such that the selected region of the original image is magnified and viewed while preserving the context of the selected region.

Abstract
A method for digital image magnification in a graphical user interface is disclosed. In contrast with prior methods which magnify a selected region of an original image without preserving its context, the present method provides a method for magnification that allows simultaneous viewing of the magnified image and its unmagnified context. In a preferred embodiment, the method provides a floating window 122! superimposed on an original image. Displayed within the floating window is a magnified image of a selected region of the original image. The floating window is centrally positioned over the selected region. In one aspect of the invention, the floating window is partially transparent so that portions of the original image within the floating window 124! are displayed in a faint manner in comparison to portions of the original image outside the floating window 126!. As the selected region is moved, typically by a user-controlled pointing device, the floating window 122! also moves.

7. A method for dynamically magnifying a moveable selected region of a video image comprising the steps of:
-
providing an arbitrary moveable selection region; creating a magnified floating plane of image data corresponding to said moveable selection region; dynamically magnifying the moveable selection region; restoring image data outside of the moveable selection region.

8. A method for dynamically magnifying a selected portion of a moving digital video image moving at a selected frame rate, while preserving the visual context of the overall image comprising the steps of:
-
selecting an arbitrary region of the moving video image for magnification; providing a floating plane of data corresponding to the selected region; refreshing the contents of the selected region in synchronization with the frame rate of the moving video image; dynamically magnifying the digital video image in the selected region; and restoring the digital video image outside the selected region to preserve the context of the overall video image.

9. A method of digital image magnification in a graphical user interface, the method comprising:
-
selecting for magnification a selected region of an original image in the graphical user interface; superimposing on the original image a floating plane region in the graphical user interface containing a magnified image of the selected region, the floating plane region having an area larger than an area of the selected region and smaller than an area of the original image; and in response to input from a user moving the selected region, moving the floating plane while the selected region is moved, and dynamically modifying the magnified image of the selected region to correspond to the selected region. - View Dependent Claims (10, 11)
