## Background
TECHNOLOGICAL FIELD
Embodiments of the present invention relate generally to image visualization and editing technology and, more particularly, relate to methods and apparatuses for facilitating generation and editing of multiframe images.
BACKGROUND
The modern computing era has brought about a tremendous expansion in computing power as well as increased affordability of computing devices. Many computing devices available to consumers now have sufficient processing capabilities to perform advanced image processing techniques. One such advanced image processing technique is the generation of a multiframe image using multiple images of a common scene combined into a single multiframe output image. The multiframe output image may show more objects of the scene in focus and/or may show greater detail of the scene than any one single image from which the multiframe image was generated. Accordingly, multiframe image processing provides a useful image enhancement technique to consumers.
However, although algorithms have been developed for multiframe image processing and computing devices capable of performing multiframe image processing are now available to consumers at affordable prices, consumers may not be able to take advantage of multiframe image processing techniques for enhancing images due to a lack of a user interface for facilitating the generation and editing of multiframe images.

In this regard, the image capture circuitry 130 may be configured to automatically determine distances to various objects in the scene depicted in the viewing frame of the image capture circuitry 130 and capture a sequence of images, each focused at one of the determined distances. The image capture circuitry 130 may then be configured to save the images, such as to the memory 122. Accordingly, a plurality of pictures of a common scene may be captured by the image capture circuitry 130 using settings automatically determined by the image capture circuitry 130 and/or manually configured by a user. Images depicting a “common scene” may depict a substantially similar scene, but may be captured using different settings. In this regard, images depicting a “common scene” may not necessarily depict the exact same area, but may at least depict substantially overlapping areas such that multiple images may be combined using multiframe image processing to generate an enhanced multiframe image.
In embodiments wherein the image processing apparatus 102 does not comprise an image capture circuitry 130 and/or in embodiments wherein images processed by the image processing circuitry 128 may be captured by another device, it will be appreciated that images may be transferred to the image processing apparatus 102 and stored at least temporarily in the memory 122 and/or may be accessed by the image processing circuitry 128 from a remote device, such as a user device 304. These images captured by another device may be captured similarly as described above in connection with the image capture circuitry 130.
The image processing circuitry 128 is configured in some embodiments to access a plurality of images, such as may be stored in memory 122 and/or to access a plurality of images stored in a remote device, such as the user device 304 and group the plurality of images into one or more groups of images. Each group of images may comprise a plurality of images depicting a common scene. In some embodiments, the plurality of images may be captured by different users and/or with several different devices (e.g., with a plurality of user devices 304). Groups may thus be formed from a plurality of images depicting a common scene captured by different users, with different devices, and/or at different times. The image processing circuitry 128 may be configured to perform the grouping automatically and/or with the assistance of user input. The image processing circuitry 128 may be configured to visually analyze images to group images depicting a common scene. Additionally or alternatively, the image processing circuitry 128 may be configured to utilize data associated with one or more images, such as metadata, defining position information (e.g., Global Positioning System coordinates) defining a location at which one or more images were captured, date information defining a date on which an image was captured, time information defining a time at which one or more images were captured, information defining an order in which two or more images were captured, and/or other information associated with one or more images or that may be obtained through analysis of one or more images to group images depicting a common scene. In some embodiments, the image processing circuitry 128 may be configured to group images when the images are captured. For example, in embodiments wherein the image capture circuitry 130 is configured to automatically capture a plurality of images at various settings when a user triggers capture of an image, the plurality of images may be automatically grouped by the image processing circuitry 128.
In embodiments wherein a user may assist grouping of images, the image processing circuitry 128 may be configured to cause automatically determined groups to be displayed for user verification and/or to prompt a user to select a group for an image(s) that the image processing circuitry 128 was not able to group. Additionally or alternatively, the image processing circuitry 128 may be configured to group images based at least in part upon a user's manual selection of a group for one or more images.
After the image processing circuitry 128 has grouped images, the image processing circuitry 128 may be further configured to mark one or more grouped images to denote a group into which the grouped image(s) was grouped. In this regard, the image processing circuitry 128 may be configured to save images belonging to a common group to a common group folder, such as in the memory 122. Additionally or alternatively, the image processing circuitry 128 may be configured to associate a group tag, such as, for example, a metatag, with a grouped image to identify the group in which the image was grouped. The image processing circuitry 128 may be configured to modify a file name of a grouped image to reflect the group in which the grouped image was grouped, such as by appending a group name to the file name. The image processing circuitry 128 may mark grouped images by saving images grouped in a common group to a single group file, such as, for example, a ZIP file.
The image processing circuitry 128 is configured in some embodiments to determine a single reference image for a group. The reference image may be determined from among the images of the group and the reference image may be associated with the respective group for which the reference image was determined. The image processing circuitry 128 may be configured to determine a reference image for a group through visual analysis of the images of the group to determine the image having the best visual quality of the images in the group, by determining user selection of a reference image for the group, through predefined criteria (e.g., default criteria and/or user defined criteria, such as, for example, first image captured in the group), and/or the like.
In some embodiments, the image processing circuitry 128 is configured to cause one or more reference images representative of the respective groups with which they are associated to be displayed to a user. This display of a reference image(s) may provide a user interface enabling the user to select a displayed reference image to enhance using multiframe image processing applied by the image processing circuitry 128. For example, the image processing circuitry 128 may be configured to cause the one or more reference images to be displayed in an interactive image gallery, such as that illustrated in FIG. 4. In this regard, FIG. 4 illustrates a multiframe image gallery viewing window 400 that may be displayed to a user. The viewing window 400 depicts two reference images—“window.jpg” 402 and “room.jpg” 404, each of which is associated with a group comprising a plurality of images depicting a common scene. For example, images 406, 408, and 410 of the group with which “window.jpg” 402 is associated and which depict various captures of the same window are illustrated in the lower portion of FIG. 4. In an exemplary embodiment, the images 406, 408, and 410 are not visible to the user within the multiframe image gallery viewing window 400 and are illustrated in FIG. 4 merely to illustrate how a representative reference image for a given group of images depicting a common scene may be displayed.
A user viewing one or more displayed reference images may select a reference image, such as through tactile selection on a touch screen display, keying an input key, selecting a reference image with a cursor, and/or other input selection means. The image processing circuitry 128 may be configured to determine this selection of a displayed reference image. In embodiments, such as that illustrated in FIG. 4 wherein multiple reference images are depicted in a gallery and the user selects one of the reference images, the image processing circuitry 128 may be configured to cause only the selected reference image to be illustrated, such as shown in FIG. 5 wherein the user has selected the “window.jpg” 402.
The user may further select at least a portion of a displayed reference image. The selection of a reference image itself may comprise the selection of at least a portion (e.g., selection of the entire reference image). Additionally or alternatively, a user may select at least a portion of a displayed reference image by defining boundaries of the selected portion, such as by sizing a box 502 illustrated in FIG. 5 to select at least a portion of the displayed reference image. Although the box 502 comprises a rectangle, it will be appreciated that selection of at least a portion of a displayed reference image may be defined using any shape or selection means, such as free form drawing, a circle, selection of a plurality of points defining a selected portion, any polygon shape, and/or the like. In another example, a selection of at least a portion of the displayed reference image may be defined using a single point, such as may be defined by a user by, for example, selecting a point on the displayed image with a touch screen display, selecting a point on the displayed image with a cursor, and/or the like. The image processing circuitry 128 is configured in some embodiments to determine the selection of the at least a portion of a displayed reference image. The selected at least a portion defines a region of interest (ROI) of the reference image. In some embodiments, the user is enabled to select more than one portion of a displayed reference image and so the image processing circuitry 128 may be configured to determine the selection of multiple selected portions of the displayed reference image, which define multiple ROIs.
The user may additionally select an enhancement(s) to apply to the ROI(s). The enhancement may, for example, comprise sharpening the focus of the ROI(s). The image processing circuitry 128 may be configured to determine such a selection of an enhancement. Additionally or alternatively, the image processing circuitry 128 may be configured to analyze the ROI(s) to automatically select an enhancement(s) to apply to the ROI(s) to enhance the visual quality of the ROI(s). In embodiments wherein multiple ROIs have been defined, the user may select a different enhancement(s) to apply to each ROI and/or the image processing circuitry 128 may be configured to analyze each ROI independent of the other ROI(s) to automatically select an enhancement(s) to apply to each respective ROI.
The image processing circuitry 128 is configured in some embodiments to determine, based at least in part on the ROI(s) and/or on the selected enhancement(s), one or more images from the group of images with which the reference image is associated to use in combination with the reference image for generation of a multiframe image having enhanced visual qualities compared to the reference image. The image processing circuitry 128 may further be configured to determine a multiframe image processing technique(s) to apply to the ROI(s) based at least in part on the selected enhancement(s) and/or on the determined one or more images to use in combination with the reference image. In this regard, wherein multiple ROIs have been defined, the image processing circuitry may determine a multiframe image processing technique to apply to each ROI based at least in part upon the selected enhancement(s) for each respective ROI and/or on the determined one or more images to use in combination with the reference image. The determined multiframe image processing technique(s) may comprise, for example, a multiframe high dynamic range (HDR) technique, such as may be used to enhance visibility of the ROI. In another example, the determined multiframe image processing technique(s) may comprise an extended-depth-of-focus (also referred to as extended-depth-of-field) (EDOF) technique, such as may be used to enhance the sharpening of an object displayed in the ROI by combining one or more determined images captured at different focus settings with the reference image (e.g., to generate an “all-in-focus image”). It will be appreciated that HDR and EDOF techniques are merely provided as examples of multiframe image processing techniques that the image processing circuitry 128 may be configured to determine to use for generation of a multiframe image and other multiframe image processing techniques may be determined and used in addition to or in lieu of these techniques.
The image processing circuitry 128 may then be configured to generate a multiframe image using the determined one or more images in combination with the reference image to generate the resulting multiframe image. The image processing circuitry 128 may use the determined multiframe image processing technique(s) to generate the multiframe image. Once the multiframe image has been generated, the image processing circuitry 128 may be configured to cause the multiframe image to be displayed to the user and/or may save the multiframe image to the memory 122.
