## Background
PRIORITY CLAIM
This application is a continuation of the application entitled “Drag Handle for Applying Image Filters in Picture Editor”, application Ser. No. 13/459,490, filed Apr. 30, 2012, which in turn claims priority to Provisional Application No. 61/605,417 entitled “Drag Handle for Applying Image Filters in Picture Editor”, filed Mar. 1, 2012. These prior applications, including the entire written description and drawing figures, are hereby incorporated into the present application by reference. This application is further related to application entitled “Drag Handle for Applying Image Filters in Picture Editor”, Application Ser. No. 13/552,840, filed even date herewith.


BACKGROUND
When applying filters to images in picture editor applications, it is often difficult for a user to discern the changes made to an image in the application of various filters and, as such, it is often difficult for the user to select the best filter or filters to effect desired image processing. In some cases, the user can revert back to the original picture but must try to retain a recollection of the image to determine whether a particular filter is desired. In other cases, “before” and “after” images can be placed side by side for viewing, but the changes in the image for a particular filter are applied to an entire image, making it difficult for the user to gain perspective on the changes made to an image through the application of filters, other than to form a generalized impression about previously applied filters.
It would be useful to provide a more intuitive, straightforward and user friendly approach for the application of image filters in picture editor applications.

As previously described, software programs or applications, referred to herein as applications, may be executed on an electronic device have a touch screen with a viewable area. In particular, photo or picture editors may be run as part of a photo application, for example, in order for a user to select and then apply changes to a chosen image using a selected filter. In accordance with various illustrative embodiments presented herein, a filter may be dynamically applied to an image in a manner that is easily controllable by a user of a photo editor application and that allows the user to progressively see changes to the image as the filter is being applied. The use of a drag handle by a user in a user interface of a photo editor application allows the user to focus on the image as it changes during application of the filter.
Referring now to FIG. 5, an illustration 500 of a user interface of a picture editor application running on an electronic device is shown. Electronic device 510 has a viewable area 520 of a touch screen in which the user interface of a picture editor application is displayed. A number of display parameters 585a, 585b, 585c, and 585d, corresponding to Rotate, Crop, Enhance, and Filters, respectively, can be changed in the picture editor application. It can be seen that the “Filters” option 585d in the picture editor application has been selected by its highlighted status, and this selection is reflected in panel 520 as shown. A number of selectable filters available for selection are displayed in a selection area 540 of the screen. In this particular example, previews 545, 550, 555, 560 corresponding to selectable filters Black & White, Sepia, Lomo, and Antique applied to image 530, respectively, are displayed in the selection area 540 of the screen. As shown here, the previews 545, 550, 555, and 560 may be thumbnail views.
The selectable filters, represented by previews 545, 550, 555, and 560, may be displayed, as shown here, in a list that is scrollable; thus, there may likely be more filters than the four filters currently displayed: Black & White, Sepia, Lomo, and Antique. The ordering of the filters in the selection area 540 may be arranged in various ways, including placing the most popular or most used filters first, alphabetically, most recent, etc.
The selected filter is this particular example is Black & White filter preview 545, which is highlighted by the placement of a highlighted box around it, as shown. The selected filter may be highlighted or indicated in other ways, such as by placing a color background behind it, outlining it in some way, etc. It is noted that the selected filter preview 545 is in fact also highlighted by the absence of its drag handle 570 from the selection area 540. The drag handle 570 associated with the selected filter 545 may be dynamically applied to image 530 in a manner that is easily controllable by control of the drag handle by the user, thereby allowing the user to progressively see changes to the image as the selected filter 545 is applied. The use of drag handle 570 by a user allows the user to focus on the image 530 and to see how it progressively changes during application of Black & White filter 545, without having to remember how the image changes in response to application of this filter.
In this particular example, the user has moved drag handle 570 over a portion 575 of image 530; the selected Black & White filter 545 has been applied has the user moved drag handle 570 over this portion 575. The selected Black & White filter 545 has only been moved over a portion of image 530 and the unfiltered portion 580 shows the image in its original “raw” form with no filtering applied. The draft handle 570 is connected to the area where the user is “dragging” the handle. So, if a user dragged out the handle, but then released the handle, the handles does not stay in that place on the screen; if the handle was beyond the threshold when released, it is applied to the entire image and if the handle was not beyond the threshold when released it is put “back” with its associated filter in the preview area, where it was originally located, without application of the associated filter to the image. This dynamic and partial application of a selected filter to a portion of a displayed image allows the user to progressively see changes to the image as the selected filter is applied and also allow the user to focus on the image as it changes. There is no need for the user to try to recollect how an image previously looked when filter was applied.
As indicated by the directional arrows of drag handle 570, the selected Black & White filter 570 has been applied to the image 530 by dragging the handle in a right-to-left horizontal motion by the user. The user can control movement of drag handle by a user finger or by use of a mouse, stylus or the like. The drag handle could also be configured to apply a selected filter in a left-to-right horizontal motion across the image, a top-to-bottom vertical motion across the image, a bottom-to-top vertical motion across the image, or even a corner-to-corner diagonal motion across the image. Of course, it is understood that rotation of the device itself may change a horizontal motion to a vertical motion across the image, and vice-versa. The partial and dynamic application of a filter in response to user manipulation of a drag handle remains unchanged.
In accordance with certain aspects, a selected filter may be applied to the entire image displayed by the electronic device when the drag handle is moved beyond a threshold line in the image that is representative of a threshold portion of the image. Where the threshold line and threshold portion of the image reside may be defined in the picture editor application and that definition may be changed by the user if desired. The threshold portion of the image may be defined as a percentage of a width dimension of the image displayed on the screen and so movement of the drag handle beyond that percentage would cause the selected filter to be applied to the entire image. For example, if the threshold portion is approximately 50% of the width of the image, movement of the drag handle beyond 50% of the width of the image will cause the selected filter to be applied to the entire image. Application of the selected filter to the rest of the image 580 once the threshold line and threshold portion of the image may be exceeded may happen quickly, in a snap application of the filter to the image, or the selected filter may be applied progressively in the direction of movement of the drag handle, in this case from right to left. If the threshold portion is approximately 75% of the width of the image, movement of the drag handle beyond 75% of the width of the image will cause the selected filter to be applied to the entire image, meaning application of the selected filter to the non-filtered, non-threshold portion of the image in a direction of movement of the drag handle.
It can thus be seen that once the drag handle has been dragged beyond a threshold line in the image, if the handle is released, then the filter is applied to the rest of the image. Alternately, if the handle is released before the threshold portion or line is passed, such as by the user removing a finger from the drag handle when using a touch screen device, removing a stylus from the drag handle, or removing a mouse from the drag handle before the threshold portion is passed, the selected filter is not applied. The image may then be displayed in an unfiltered state on the screen of the electronic device or the image may be displayed in a previously displayed, filtered state. Deselection of a selected filter may also occur in response to a tap on the preview of the selected filter in the selection are of the screen. Application of a selected filter in response to user manipulation of the drag handle thus provides a simple, intuitive way to apply filters without requiring additional user input to undo or to apply filter buttons, or to display separate “before” and “after” pictures of the image.
Alternately, a selected filter may be applied to an entire displayed image in response to a tap on the portion of the image to which the selected filter has been applied; in this example, in response to a tap on portion 575. When the screen is a touch responsive screen, for example, a tap by the user on portion 575 may cause the selected filter to be applied to the entire image.
It is further envisioned that changing a display parameter of a displayed image will cause a corresponding change to the displayed filter previews 545, 550, 555, 560. Thus, rotating a displayed image on the screen of the electronic device will cause the displayed filter previews 545, 550, 555, 560 to also be rotated.
Non-selected filters 550, 555, 560 are each available for selected and each have an associated drag handle 550a, 555a, 560a as shown. If a user wishes to apply a filter that is not currently selected, the user selects the desired filter and can then move the drag handle associated with the selected filter across the displayed image. Selection of another filter deselects the currently selected filter and removes the previously applied filter. The previously selected and applied filter may seem to disappear from the image to not convey simultaneously the application of multiple filters.
In certain circumstances, some filters may be inactivated for selection in the selection area of the display screen and thus not be selectable by the user. Such would be the case, for example, for a selectable filter that depends on face recognition when it is determined that the image does not contain any face(s).
It can be seen that application of a selected filter in response to user manipulation of the drag handle thus provides a simple, intuitive way to apply filters without requiring additional user input to undo or to apply filter buttons, or to display separate “before” and “after” pictures of the image. Referring now to FIG. 6, flowchart 600 illustrates dynamically applying image filters. In Block 605, a selected filter is dynamically applied to a portion of an image displayed on a screen as the drag handle is moved across the image. As discussed, the portion of the image to which the selected filter is applied is changeable in size with motion of the drag handle across the image and is determined by a position of the drag handle on the screen. At Block 610, changes to the image caused by application of the selected filter are dynamically displayed as the drag handle is moved across the displayed image. As will be appreciated from reference to flowchart 700 of FIG. 7, these operations may involve many considerations.
At Block 710, selectable filters are displayed in a selection area of the screen and flow continues to Block 745. If a filter is selected by the user, the flow continues to Decision Block 750, where the inquiry is whether the drag handle is being moved across the displayed image. If yes, then the position of the drag handle on the screen is determined at Block 755. The selected filter is then dynamically applied to the displayed image as the drag handle is moved across the image at Block 760. The determined position of the drag handle is compared to a threshold line to determine whether the drag handle has been moved beyond a threshold line or threshold portion of the image at Decision Block 765. If yes, then the selected filter may be applied to the entire image displayed, such as by dynamically applying it to a portion of the image not previously filtered with the selected filter.
If the drag handle has not moved beyond the threshold, the flow continues from Decision Block 765 to Decision Block 775. The inquiry here is whether the drag handle is released before being moved across the threshold. If yes, then the selected filter is not applied to the displayed image after the drag handle is released. Otherwise, the flow returns to Decision Block 750.
Referring back to Decision Block 750, if the drag handle is not being moved across the image, then the inquiry at Decision Block 785 is whether the filter has been previously applied to a portion of the image. If yes, then at Block 790 the inquiry is whether a tap has been received by a touch responsive screen on the portion of the image to which the selected filter has been previously applied. If yes, then at Block 795 the selected filter is applied to the entire image in response to the tap. If no, the flow returns to Decision Block 750.
Following display of selectable filters so that they can be selected by a user at Block 710, there are a number of optional actions that may be undertaken and have been described above. These optional actions are indicated by dashed lines. The inquiry at Decision Block 715 is whether the displayed image contains faces. If no, then selectable filters that use face recognition as part of the filtering may inactivated at Block 720. Alternately, Block from Block 710 may go to Block 725 where a preview of each the selectable filters are displayed. In FIG. 5 these previews where thumbnail previews 545, 550, 555, and 560, for instance. Or, the flow may continue to Block 730, where, in response to a display parameter of the image changing, the preview of each of the selectable filters are updated and displayed in accordance with the changed display parameter. Further, the selected filter may be highlighted or otherwise indicated as being selected in the selection area of the screen, at Block 735. The selected filter may be deselected in response to a tap on the displayed preview of the selected filter at Block 740.
The order in which the optional operations represented in Blocks 715-740 occurs is not predetermined or predefined, and these operations may occur in any order or not at all after occurrence of the operation of Block 710. Thus, while the blocks comprising the methods are shown as occurring in a particular order, it will be appreciated by those skilled in the art that many of the blocks are interchangeable and can occur in different orders than that shown without materially affecting the end results of the methods.

dynamically applying a selected image effect filter of a plurality of selectable image effect filters to a portion of an image rendered on a screen as a drag handle also rendered on the screen is moved across the image to dynamically change the size of the filtered portion of the image with respect to the size of an unfiltered portion of the image, the portion of the image to which the selected image effect filter is applied being dynamically changeable in size with motion of the drag handle across the image and determined by a position of the handle on the screen;
applying the selected image effect filter to the entire image rendered on the screen in response to the handle being moved and released beyond a threshold line in the image representative of a threshold portion of the image, the threshold line being user definable; and
dynamically displaying the changes to the portion of the image caused by application of the selected image effect filter as the handle is moved across the image rendered on the screen.

5. The method of claim 4, where the threshold line is predefined in a picture editor application and is user definable in the picture editor application.

6. The method of claim 4, where the threshold portion of the image is a defined percentage of a width dimension of the image rendered on the screen and is one of approximately 50% of the width of the image and approximately 75% of the width of the image.

7. The method of claim 4, further comprising in response to the handle being moved beyond the threshold line in the image dynamically applying the selected image effect filter to the entire image in a snap application of the selected image effect filter to the entire image.

8. The method of claim 7, further comprising in response to the handle being moved beyond the threshold line in the image dynamically applying the selected image effect filter to a non-threshold portion of the image to which the selected image effect filter has not been applied.

9. The method of claim 4, further comprising applying the selected image effect filter to the entire image rendered on the screen in response to the handle being moved beyond the threshold line in the image representative of the handle being moved beyond a threshold portion of the image even when the handle is released after being moved beyond the threshold line in the image.

10. A method of dynamically applying image effect filters on an electronic device, comprising:
dynamically applying a selected image effect filter of a plurality of selectable image effect filters to a portion of an image rendered on a screen as a drag handle also rendered on the screen is moved across the image to dynamically change the size of the filtered portion of the image with respect to the size of an unfiltered portion of the image, the portion of the image to which the selected image effect filter is applied being dynamically changeable in size with motion of the drag handle across the image and determined by a position of the handle on the screen;
displaying for selection the plurality of selectable image effect filters in a selection area of the screen;
indicating the selected image effect filter of the plurality of selectable image effect filters as selected in the selection area of the screen by highlighting the selected image effect filter in the selection area by one or more of placement of a highlighted box around the selected image effect filter and a color background behind the selected image effect filter; and
displaying the changes to the portion of the image caused by application of the selected image effect filter as the handle is moved across the image rendered on the screen.

11. The method of claim 10, further comprising:
displaying for selection the plurality of selectable image effect filters in a selectable listing of selectable image effect filters, the selectable listing being scrollable in the selection area of the screen.

12. The method of claim 1, wherein the drag handle is coupled to a first boundary of one or more boundaries of the image and to a second boundary of the one or more boundaries of the image.

13. The method of claim 1, wherein a boundary of the filtered portion extends from a first boundary of one or more boundaries of the image to a second boundary of the one or more boundaries of the image.

14. The method of claim 3, wherein the drag handle is coupled to a first boundary of one or more boundaries of the image and to a second boundary of the one or more boundaries of the image.

15. The method of claim 3, wherein a boundary of the filtered portion extends from a first boundary of one or more boundaries of the image to a second boundary of the one or more boundaries of the image.
