Definitions

  • TECHNICAL FIELD This invention relates to magnification and editing of an image.
  • the user loses the visual context for the magnified portion of the image relative to the unmagnified portion of the image. Because it is unclear which portion of the image is being modified, or because it is unclear how any modifications to that portion will fit with the rest of the image, the user may be unable to make modifications that are appropriate for that portion of the image relative to the rest of the image. The user may be able to make modifications that are responsive to the small-scale features revealed in the magnified view, but the user cannot make modifications that are responsive to the visual context of the complete image.
  • the problem of identifying how the magnified portion of the image corresponds to the rest of the image is also addressed in part by presenting the magnified view of a portion of an image next to the original image and providing cues to indicate the correspondence between them. For example, manipulation of one window may cause correlated changes in the portion of the image presented in the other window. Alternatively, the correspondence between the two images may be inferred by comparing the markings on horizontal and vertical rulers in each of the views. In this case, a point at particular coordinates in the magnification window corresponds to the point at the same coordinates in the original view.
  • the user defines the size of the magnified view of a portion of the image, the degree of the magnification of a portion of the image, or the location of the magnified version of a portion of the image relative to the image.
  • the user manipulates the magnified view to make modifications to the image. These modifications are applied to the corresponding portion of the image.
  • the modifications result in the change of at least one pixel value.
  • the pixels in the image that correspond to the changed pixels in the magnified view are also changed.
  • FIG. 1 is a diagrammatic view of an image with a portion to be magnified
  • FIG. 2 is a diagrammatic view of an image with a magnification window superimposed on it;
  • FIG. 3 is a diagrammatic view of an image with a magnification window in which edits have been made
  • FIG. 4 is a diagrammatic view of an image with edits that were made in a magnification window
  • FIG. 6 is a diagrammatic view of the image as in FIG. 5 with a different portion magnified in the adjacent window.
  • Like reference numbers and designations in the various drawings indicate like elements.
  • the user may define the size of the magnification window 7.
  • the user may specify the degree of magnification of the magnified portion 3.
  • the size of the magnification window 7 may be calculated.
  • the magnification window 7 is larger than the magnified portion 3 of the image 1.
  • the portion of the magnification window 7 excluding the magnified portion 3 of the image 1 will be a hidden region 8. This hidden region 8, and features within this hidden region 8, such as part of the cloud-like feature 6, will be obscured by a magnification window of the selected size 7.
  • the system presents a magnified version 9 of the magnified portion 3 of the image 1 according to the selected magnification 7 in a magnification window 10.
  • the magnification window 10 is superimposed on the original window 2 and centered on the magnified portion 3 of the image 1.
  • the magnification window 10 obscures the magnified portion 3 of the image 1 and the hidden area 8 of the image 1, including part of the cloud-like feature 6.
  • the magnified version 9 of the magnified portion 3 of the image 1 does not align smoothly with the visible part 11 of the unmagnified portion 4.
  • the line that indicated three mountain-like peaks in the image 1 is broken at the boundary of the magnification window 10 and the visible part 11 of the unmagnified portion 4.
  • the user may apply modifications to the magnified version 9 of the portion 3 of the image 1 that is shown in the magnification window 10.
  • the user may modify the magnified version 9 by changing pixels so that a feature such as the ravine-like line 25 no longer exists.
  • the user also may modify the magnified version 9 by changing pixels to add features.
  • the user may add a feature such as the word "ADOBE" 13.
  • Such modifications 13 may be responsive to small-scale features, such as the triangular shape 12, that were made obvious in the magnified version 9 of the magnified portion 3 of the image 1 by the magnification of the portion 3 of image 1.
  • the upper portion of the letter "A" of "ADOBE" is aligned with the triangular shape 12.
  • the present invention allows the user of a computer to create a magnified version of a portion of an image, with the magnified version smaller than the image but not superimposed upon it.
  • the context for the magnified version of the image is provided by examining visual cues applied to the image and by allowing the user to change the portion of the image that is shown in the magnified version.
  • the magnified portion 3 of the image 1 is delimited by a dotted line 16.
  • This portion 3 of the image includes one of the three mountain-like peaks and a ravine-like line 25.
  • the system presents a magnified version 9 of the magnified portion 3 of the image 1 in a magnification window 17.
  • the magnification window 17 is adjacent to the original window 2.
  • the location of the magnified version 9 shown in the magnification window 17 is clearly and continuously indicated by the dotted line 16.
  • the user can change the portion of the image 1 that is shown in the magnification window 17.
  • the user has selected another portion 19 of the image 1, which is above and overlaps the portion 3 of the image that previously shown in the magnification window 17.
  • the magnified version 20 of the magnified portion 19 of the image 1 now appears in the magnification window 17, showing a magnified portion 21 of the cloud-like feature 6 that was previously in the unmagnified portion 4 of the image 1.
  • the invention can be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them.
  • Apparatus of the invention can be implemented in a computer program product tangibly embodied in a machine-readable storage device for execution by a programmable processor; and method steps of the invention can be performed by a programmable processor executing a program of instructions to perform functions of the invention by operating on input data and generating output.
  • the invention can be implemented advantageously in one or more computer programs that are executable on a programmable system including at least one programmable processor coupled to receive data and instructions from, and to transmit data and instructions to, a data storage system, at least one input device, and at least one output device.
  • Each computer program can be implemented in a high-level procedural or object-oriented programming language, or in assembly or machine language if desired; and in any case, the language can be a compiled or interpreted language.
  • Suitable processors include, by way of example, both general and special purpose microprocessors.
  • a processor will receive instructions and data from a read-only memory and/or a random access memory.
  • a computer will include one or more mass storage devices for storing data files; such devices include magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and optical disks.
  • the invention can be implemented on a computer system having a display device such as a monitor or LCD screen for displaying information to the user and a keyboard and pointing device such as a mouse or a trackball by which the user can provide input to the computer system.
  • the computer system can be programmed to provide a graphical user interface through which computer programs interact with users.
