Abstract

A method and apparatus for viewing digital images is provided. A digital image may be viewed using a digital image system that employs a virtual loupe. A virtual loupe comprises a lens region and a target region. The lens region and the target region may each be a bounded area displayed on a display. A user may position the target region over a digital image displayed on the display to cause a depiction of visual information associated with the target region to be displayed in the lens region. The user can configure the virtual loupe to display visual information in the lens region at different levels of magnification. The lens may automatically move and change in orientation with respect to the target region as the target region moves on the display to ensure that the display of the lens region on the display is always unobscured.

Claims

1. A method, comprising:

displaying an image;

displaying a virtual loupe comprising a target region and a lens region,

wherein the lens region is displayed at a fixed distance from the target region,

wherein the lens region is displayed at a first orientation relative to the target region;

wherein the lens region is separate from the target region;

receiving a first user input selecting a first location, of the target region, on the image;

wherein a depiction of a first visual information associated with the first location is displayed within the target region;

wherein a magnified depiction of the first visual information is displayed within the lens region;

receiving a second user input moving the target region from the first location to a second location on the image;

in response to receiving the second user input,

moving the target region to the second location;

moving the lens region to concurrently maintain (1) the fixed distance of the lens region from the target region and (2) the first orientation of the lens region relative to the target region;

wherein a depiction of a second visual information associated with the second location is displayed within the target region;

wherein a magnified depiction of the second visual information is displayed within the lens region.

2. A storage device storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the method steps as recited in claim 1.

3. A storage device storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the method steps as recited in claim 1.

4. The method as recited in claim 1, further comprising:

receiving a third user input moving the target region to a third location on the image;

in response to receiving user input moving the target region to a third location, moving the target region to the third location;

determining that the first orientation of the lens region relative to the target region should be changed to a second orientation;

displaying the lens region at a second orientation relative to the target region and at the fixed distance from the target region;

wherein a depiction of a third visual information associated with the third location is displayed within the target region;

wherein a magnified depiction of the third visual information is displayed within the lens region.

5. A storage device storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the method steps as recited in claim 4.

6. The method as recited in claim 4, wherein determining that the first orientation of the lens region relative to the target region should be changed to a second orientation comprises determining that displaying the lens region at the first orientation from the target region would result in the lens region being closer to a display edge than the target region.

7. A storage device storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the method steps as recited in claim 6.

8. The method as recited in claim 4, wherein determining that the first orientation of the lens region relative to the target region should be changed to a second orientation comprises determining that displaying the lens region at the first orientation from the target region would result in the lens region not being fully displayed.

9. A storage device storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the method steps as recited in claim 8.

10. The method as recited in claim 4, wherein the second orientation of the lens region relative to the target region is based on aligning the second orientation with a center of a display.

11. A storage device storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the method steps as recited in claim 10.

12. The method as recited in claim 4, wherein the second orientation of the lens region relative to the target region is based on which sub-region of a display comprises the second location of the target region.

13. A storage device storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the method steps as recited in claim 12.

14. The method as recited in claim 4, wherein displaying the lens region at a second orientation relative to the target region comprises displaying the lens region at intermediate locations between the first orientation relative to the target region and the second orientation relative to the target region.

15. A storage device storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the method steps as recited in claim 14.
