DETAILED DESCRIPTION

Embodiments of the present disclosure relate to systems and methods that can be executed in an image capture device. More specifically, embodiments of the disclosure relate to systems and methods of presenting image setting adjustment user interface elements in a user interface associated with the image capture device. In the context of this disclosure, an image capture device can include a camera, video camera, a mobile device with an integrated image capture device, or other devices suitable to capturing imagery and/or video as can be appreciated. In some embodiments, an image capture device according to an embodiment of the disclosure can include a device such as a smartphone, tablet computing system, laptop computer, desktop computer, or any other computing device that has the capability to receive and/or capture imagery via image capture hardware.
Accordingly, image capture device hardware can include components such as lenses, image sensors (e.g., charge coupled devices, CMOS image sensor, etc.), processor(s), image signal processor(s), a main processor, memory, mass storage, or any other hardware or software components that can facilitate capture of imagery and/or video. In some embodiments, an image signal processor can be incorporated as a part of a main processor in an image capture device module that is in turn incorporated into a device having its own processor, memory and other components.
An image capture device according to an embodiment of the disclosure can provide a user interface via a display that is integrated into the image capture device. The display can be integrated with a mobile device, such as a smartphone and/or tablet computing device, and can include a touchscreen input device (e.g., a capacitive touchscreen, etc.) with which a user may interact with the user interface that is presented thereon. The image capture device hardware can also include one or more buttons, dials, toggles, switches, or other input devices with which the user can interact with software executed in the image capture device.
Referring now to the drawings, FIGS. 1A-1B show a mobile device 102 that can comprise and/or incorporate an image capture device according to various embodiments of the disclosure. The mobile device 102 may comprise, for example, a processor-based system, such as a computer system. Such a computer system may be embodied in the form of a desktop computer, a laptop computer, a personal digital assistant, a mobile device (e.g., cellular telephone, smart phone, etc.), tablet computing system, set-top box, music players, or other devices with like capability. The mobile device can include, for example, an image capture device 104, which can further include a lens system as well as other hardware components that can be integrated with the device to facilitate image capture. The mobile device 102 can also include a display device 141 upon which various content and other user interfaces may be rendered. The mobile device 102 can also include one or more input devices with which a user can interact with a user interface rendered on the display device 141. For example, the mobile device 102 can include or be in communication with a mouse, touch input device (e.g., capacitive and/or resistive touchscreen incorporated with the display device 141), keyboard, or other input devices.
The mobile device 102 may be configured to execute various applications, such as a camera application that can interact with an image capture module that includes various hardware and/or software components that facilitate capture and/or storage of images and/or video. In one embodiment, the camera application can interact with application programming interfaces (API's) and/or other software libraries and/or drivers that are provided for the purpose interacting with image capture hardware, such as the lens system and other image capture hardware. The camera application can be a special purpose application, a plug-in or executable library, one or more API's, image control algorithms, image capture device firmware, or other software that can facilitate communication with image capture hardware in communication with the mobile device 102.
FIG. 2 illustrates an embodiment of the various image capture components, or one example of an image capture device 104, that can be incorporated in the mobile device 102 illustrated in FIGS. 1A-1B. Although one implementation is shown in FIG. 2 and described herein, an image capture device according to an embodiment of the disclosure more generally comprises an image capture device that can provide images in digital form.
The image capture device 104 includes a lens system 200 that conveys images of viewed scenes to an image sensor 202. By way of example, the image sensor 202 comprises a charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) sensor that is driven by one or more sensor drivers 204. The analog image signals captured by the sensor 202 are provided to an analog-to-digital (ND) converter 206 for conversion into binary code that can be processed by a processor 208. The processor can also execute a user interface application 151 that can facilitate generating the user interface elements discussed herein. In some embodiments, the user interface application 151 can take the form of API's, firmware, or other software accessible to the image capture device 104 and/or a mobile device 102 or other system in which the image capture device 104 is integrated.
Operation of the sensor driver(s) 204 is controlled through a camera controller 210 that is in bi-directional communication with the processor 208. In some embodiments, the controller 210 can control one or more motors 212 that are used to drive the lens system 200 (e.g., to adjust focus, zoom, and/or aperture settings). The controller 210 can also communicate with a flash system, user input devices (e.g., buttons, dials, toggles, etc.) or other components associated with the image capture device 104. Operation of the camera controller 210 may be adjusted through manipulation of a user interface. A user interface comprises the various components used to enter selections and commands into the image capture device 104 and therefore can include various buttons as well as a menu system that, for example, is displayed to the user in, for example, a camera application executed on a mobile device 102 and/or on a back panel associated with a standalone digital camera.
The digital image signals are processed in accordance with instructions from an image signal processor 218 stored in permanent (non-volatile) device memory. Processed (e.g., compressed) images may then be stored in storage memory, such as that contained within a removable solid-state memory card (e.g., Flash memory card). The embodiment shown in FIG. 2 further includes a device interface 224 through which the image capture device 104 can communicate with a mobile device or other computing system in which it may be integrated. For example, the device interface 224 can allow the image capture device to communicate with a main processor associated with a mobile device as well as memory, mass storage, or other resources associated with the mobile device. The device interface 224 can communicate with a mobile device in various communications protocols, and this communication can be facilitated, at a software level, by various device drivers, libraries, API's or other software associated with the image capture device 104 that is executed in the mobile device.
Accordingly, as will be shown in the following drawings, a user interface application 151 executed by the image capture device and/or software that interacts with the image capture device can facilitate generation of user interface elements that allow simultaneous adjustability of multiple image settings associated with the image capture device. The user interface application 151 can generate adjustment elements in various forms that allow simultaneous adjustment of image settings associated with the image capture device, such as, but not limited to, color settings, contrast, brightness, flash settings, exposure settings, shutter settings, aperture settings, or any other settings associated with capture of imagery and/or video by the image capture device.
Therefore, reference is now made to FIGS. 3A-3B, which illustrates one example of a user interface that can be generated by the image capture device 104 or software executed by the mobile device 102 that interacts with the image capture device 104. The depicted user interface 301 provides simultaneous adjustability of multiple image settings associated with the image capture device 104. Image settings can include, but are not limited to, a brightness, a color intensity, a hue, a contrast, a sharpness, a shutter speed, a flash intensity, a flash duration, a film speed setting, an exposure value setting, a white balance setting, a noise filtering setting, a focal distance setting, an exposure index setting and an aperture size setting, or any other setting that can have an effect on the appearance of an image and/or a setting associated with the image capture device 104.
In the depicted example, the user interface 301 can link various image settings together with an adjustability user interface element 303. In the example of FIG. 3A, the adjustability user interface element 303 comprises a one dimensional element in that it allows adjustment of a slidable element 305 along a single axis. When a user adjusts the slidable element 305 along the axis, the image capture device can adjust the image settings associated with the adjustability user interface element 303 simultaneously. In the depicted example, the adjustability user interface element 303 can link brightness, color, and contrast image settings and adjust these image settings simultaneously as a user interacts with the element via an input device. The image capture device 104 can also determine a respective scale that is associated with each of the image settings linked by the adjustability user interface element 303. In other words, for each image setting associated with the element 303, the image capture device 104 can identify a minimum setting that can be associated with a first extreme of the element 303, a maximum setting can be associated with a second extreme of the element 303, and an amount by which an image setting is incremented and/or decremented as a user adjusts the slidable element 305 along the axis of the adjustability element 303. Additionally, the minimum setting, maximum setting and amount by which the image setting is changed can vary for each of the image settings linked by the adjustability element 303. Additionally, the adjustability element 303 can provide a visual cue that indicates to the user how an image setting will be changed as the user moves the slidable element 305 along the axis. FIG. 3B illustrates an alternative example where the adjustability element 303 can be rendered such that numeral indicators that indicate a level associated with an image setting can be included.
The image capture device 104 can generate various combinations of image settings that can be linked with the adjustability element 303. In some embodiments, the image capture device 104 can identify image properties associated with a captured image and/or a device mode in which the image capture device is placed. Accordingly, the image capture device 104 can then identify image settings that are applicable to the device mode and/or image the user desires to adjust. For example, if an image capture device 104 is placed in a video mode and/or the user invokes the adjustability element 103 in relation to a video captured by the image capture device 104, the adjustability element 303 generated by the image capture device can include settings that are applicable to one or both. As another example, if an image and/or device mode is black and white, the image capture device 104 can suppress color settings from appearing in the adjustability element.
Reference is now made to FIG. 4, which illustrates an example of a multi-dimensional adjustability element 403 that allows the user adjustments in at least two axes. In the depicted example, the adjustability element 403 can allow adjustment about a circular axis as well as a linear axis. In this way, the user can adjust multiple image settings via a single user interface element.
Reference is now made to FIG. 5, which illustrates an alternative example of an adjustability element 503 according to various embodiments of the disclosure. In the depicted example, the image capture device can generate an adjustability element that allows adjustment of multiple device and/or image settings via a single element. In the example of FIG. 5, the image capture device can alter a mix of image and/or device settings based at least upon a position of the slidable element 505. For example, the image capture device 104 can link certain image and/or device settings that are elated to one another.
As shown in FIG. 5, the adjustability element 503 can provide the ability to cause changes to a shutter speed as well as aperture setting associated with the image capture device. In this sense, the image capture device 104 can be placed into a shutter priority mode, as one extreme, and an aperture priority mode, as a second extreme. In a shutter priority mode, the image capture device can slow the shutter speed and narrow an aperture associated with the image capture device. In the aperture priority mode, the image capture device can widen an aperture and shorten a shutter speed associated with the image capture device. Accordingly, as the user adjusts the slidable element 505 between the depicted extremes, the image capture device 104 can create a mix of shutter speed and/or aperture size according to the distance from each extreme of the slidable element 505. As an alternative example of such a scenario, the adjustability element 503 can also allow a user to select a mixture flash intensity and/or duration on one extreme and an shutter speed or other exposure settings on another extreme.
Referring next to FIG. 6, shown is a flowchart that provides one example of the operation of a portion of a user interface application 151 executed by an image capture device 104, a mobile device 102 or any other device in which an image capture device 104 is integrated according to various embodiments of the disclosure. It is understood that the flowchart of FIG. 6 provides merely an example of the many different types of functional arrangements that may be employed to implement the operation of the portion of logic employed by the image capture device as described herein. As an alternative, the flowchart of FIG. 6 may be viewed as depicting an example of steps of a method implemented in a computing device, processor, or other circuits according to one or more embodiments.
First, in box 601, the user interface application 151 can initiate capture of one or more images and/or video by the image capture device 104. In one embodiment, the user interface application 151 can facilitate generation of a user interface through which a user can initiate image capture via the image capture device. In box 603, the user interface application 151 can identify image settings that are applicable to the image. In box 605, the user interface application 151 can generate a user interface element that, as described above, provides simultaneous adjustment of multiple image settings. In box 607, the user interface application 151 can determine whether the user interface element is modified by the user. In box 609, the user interface application 151 can cause the image capture device 104 to adjust the image settings linked by the user interface element when the element is modified by the user.
It should be appreciated that in some embodiments, image settings may be adjusted without initiating image capture as described in box 601, and that the example illustrated in the flowchart of FIG. 6 is but one non-limiting example. For example, a mobile device 102 and/or image capture application 104 can generate a user interface element providing adjustability of multiple image settings in conjunction a gallery application that allows for viewing and/or browsing of imagery and/or video stored in a mass storage device. Additionally, the user interface application 151 can be invoked to provide such an adjustability user interface element in conjunction with software that allows modification of various camera settings in a context that is unrelated to image capture. Other variations should be appreciated by a person of ordinary skill in the art.
