Description

Background Technology

[0001] This enables devices such as smart devices, mobile devices (e.g., cellular phones, tablets, smartphones), and consumer electronics to be used in a wide range of environments and for a variety of different applications. Many different types of these wireless devices, such as mobile phones, include multiple cameras to capture digital images, such as ultrawide cameras, wide-angle cameras, and / or telephoto cameras. Furthermore, telescope attachments can be added to these types of multi-camera devices to extend the focal length of the telephoto camera. However, telescope attachments may obstruct or block the field of view of other device cameras, such as ultrawide and / or wide-angle cameras. When only a narrow, magnified field of view is seen through the camera viewfinder, it becomes difficult for the user of the device to locate the telephoto camera and / or telescope attachment as a target.

[0009] Figure 11 Various components are shown in an example device that can be used to implement the telephoto camera viewfinder technology described herein. Detailed Implementation

[0010] An implementation of a telephoto camera viewfinder is described, and a technique implemented by a multi-camera device is provided to offer a viewfinder user interface that includes both a zoom view of the camera scene displayed as a zoomed preview image captured by the telephoto camera and a wide view of the camera scene displayed as a camera preview image captured by a digital camera. The viewfinder user interface also includes a zoom view indicator displayed above the camera preview image to indicate the zoom view relative to the wide view of the camera scene. The zoom view indicator may be displayed above the camera preview image in the viewfinder user interface as a bordered outline of the area of ​​the camera scene indicating the zoom view relative to the wide view. The zoom view indicator displayed above the camera preview image serves as a virtual finder scope for the telephoto camera's zoom view. When a user of the multi-camera device moves the device and changes the camera scene and / or adjusts the focal length to zoom in or out on the telephoto lens, the user can quickly locate the telephoto camera target from the zoom view shown in the area of ​​the camera scene relative to the wide view shown in the camera preview image.

[0011] In all aspects of the telephoto camera viewfinder, as described herein, the multi-camera device has a digital camera to capture digital images of the camera scene viewable in a wide field of view using the digital camera. The multi-camera device also has a telephoto camera to capture digital content of the camera scene viewable in a zoomed field of view using the telephoto camera. The multi-camera device has a display screen to display a viewfinder user interface including a zoomed field of view displayed as a zoomed preview image captured by the telephoto camera, and a wide field of view displayed as a camera preview image captured by the digital camera. The viewfinder user interface also includes a border outline displayed above the camera preview image indicating the area of ​​the camera scene in the zoomed field of view relative to the wide field of view of the camera scene. As used herein, the term "wide field of view" is relative to the "zoomed field of view" of a telephoto camera, which typically has a narrower field of view compared to the wider field of view of a digital camera.

[0012] Furthermore, multi-camera digital cameras are described as achieving the capture of digital images of a camera scene, and telephoto cameras are described as achieving the capture of digital content of a camera scene. This is merely for ease of discussion to associate the content captured by the respective camera devices. In reality, digital images (captured by a digital camera) are also digital content, and digital content (captured by a telephoto camera) can be captured in the form of digital images. As used herein, the terms "digital image" and "digital content" include any type of digital frame, digital photograph, digital image, digital video frame of a video clip, digital video, and / or any other type of digital content.

[0013] In various aspects of a telephoto camera viewfinder, the viewfinder user interface may include a wide image capture icon selectable by the user of the multi-camera device to initiate the capture of a digital image in a wide field of view of the camera scene using the digital camera. The viewfinder user interface may also include a selectable zoom image capture icon to initiate the capture of digital content in a zoomed field of view of the camera scene using the telephoto camera. Additionally, the user of the multi-camera device may select both the wide image capture icon and the zoom image capture icon substantially simultaneously to initiate both the capture of a digital image in a wide field of view of the camera scene using the digital camera and the capture of digital content in a zoomed field of view of the camera scene using the telephoto camera. The multi-camera device implements an image viewfinder module that can receive input and user selections, such as touch input from the device user, in the viewfinder user interface on the device's display screen (e.g., a touchscreen display).

[0014] As described above, the viewfinder user interface includes a border outline indicating the area of ​​the camera scene that represents a zoomed-in field of view relative to the wide field of view of the camera scene displayed above the camera preview image. As an alternative to or complement to the image capture icon, the image viewfinder module can receive touch input selections from the device user within the border outline of the area and convey control commands to initiate the telephoto camera of a multi-camera device to capture digital content within the zoomed-in field of view of the camera scene. Similarly, the image viewfinder module can receive touch input selections outside the border outline of the area and convey control commands to initiate the digital camera of a multi-camera device to capture a digital image within the wide field of view of the camera scene.

[0015] In other aspects of the telephoto camera viewfinder, users of multi-camera devices can adjust the size of the border outline (i.e., zoom field of view indicator) of an area on the camera preview image to effectively zoom out or further magnify the telephoto camera. For example, a user can touch and select an area and drag a corner or edge of the border outline to decrease or increase its size. As the user decreases the size of the border outline, the telephoto camera zooms in further, and as the user increases the size of the border outline, the telephoto camera zooms out. The image viewfinder module implemented by the multi-camera device can receive touch selection input to decrease the size of the area's border outline and control the telephoto camera to zoom out further in response to the decrease in the size of the border outline. This also works for changing the zoom preview image displayed in the viewfinder user interface. Similarly, the image viewfinder module can receive touch selection input to increase the size of the area's border outline and control the telephoto camera to zoom out in response to the increase in the size of the border outline. This also works for changing the zoom preview image displayed in the viewfinder user interface.

[0016] While the features and concepts of a telephoto camera viewfinder can be implemented in any number of different devices, systems, environments, and / or configurations, implementations of a telephoto camera viewfinder are described in the context of the following example devices, systems, and methods.

[0017] Figure 1 An example 100 of a technique for a telephoto camera viewfinder is illustrated using an image viewfinder module 104 that implements various aspects of managing a telephoto camera viewfinder as described herein. In this example 100, the multi-camera device 102 can be any type of mobile device, computing device, tablet device, mobile phone, flip phone, and / or any other type of multi-camera device. Typically, the multi-camera device 102 can be equipped with various components such as a processor system and memory, as well as references... Figure 11 The example device shown is further described as any type of electronic and / or computing device implemented by any number and combination of different components.

[0018] In this example 100, the multi-camera device 102 has a digital camera 106 and a telephoto camera 108, generally shown as a camera or telephoto camera with an attached telephoto lens (also known as a telescope accessory). Typically, the digital camera 106 includes a lens integrated into the back cover or housing of the device and has an imaging sensor, referred to as an imager. The camera imager receives light directed through the camera lens and then captures it as a digital image of the camera scene that can be viewed using the digital camera 106 in a wide field of view. For example, the digital image captured by the digital camera 106 could be a digital photograph of the environment that can be viewed using the camera. The digital camera 106 has a field of view (FOV) of the camera, referred to herein as the wide field of view of the camera scene. As further noted below, "wide field of view" is a "zoomed field of view" relative to the telephoto camera 108, which typically has a narrower field of view compared to the wider field of view of the digital camera 106.

[0019] Similarly, the telephoto camera 108 of the multi-camera device 102 includes a lens integrated into the device's rear cover or housing, and also has an imager that receives light guided through the camera lens and then captures it as digital content of the camera scene viewable in a zoomed field of view using the telephoto camera 108. For example, the digital content captured by the telephoto camera 108 can be a digital photograph of the environment viewable using the camera. The telephoto camera 108 has a field of view (FOV) of the camera, referred to herein as the zoomed field of view of the camera scene. As described above, "zoomed field of view" is relative to the "wide field of view" of the digital camera 106, and generally has a wider field of view compared to the narrower field of view of the telephoto camera 108. In embodiments, the digital camera 106 and the telephoto camera 108 may capture digital content with different focal lengths and / or different apertures.

[0020] It is worth noting that digital camera 106 is described as being implemented to capture digital images of a camera scene, and telephoto camera 108 is described as being implemented to capture digital content of a camera scene. This is merely for ease of discussion to associate the content captured by the respective cameras. In reality, digital images are also digital content, and digital content can be captured in the form of digital images. As used herein, the terms "digital image" and "digital content" include any type of digital frame, digital photograph, digital image, digital video frame of a video clip, digital video, and / or any other type of digital content.

[0021] The multi-camera device 102 has a display screen 110 on which a viewfinder user interface 112 can be displayed. The viewfinder user interface 112 includes a zoomed field of view displayed as a zoomed preview image 114 captured by the telephoto camera 108, and a wide field of view displayed as a camera preview image 116 captured by the digital camera 106. The multi-camera device 102 implements an image viewfinder module 104 that manages the display of content such as the zoomed preview image 114 and the camera preview image 116 in the viewfinder user interface 112. The image viewfinder module 104 also initiates and controls the display of a zoomed field of view indicator 118, which is displayed in the viewfinder user interface 112 above the camera preview image 116 to indicate the zoomed field of view relative to the wide field of view of the camera scene.

[0022] For example, the zoom field of view indicator 118 can be displayed above the camera preview image 116 as an outline of the border of the area 120 of the camera scene relative to the wide field of view. It is worth noting that the area 120 of the camera scene corresponds to the zoom preview image 114, which is also displayed in the viewfinder user interface 112, in this example, also displayed above the camera preview image 116. In this implementation, the zoom field of view indicator 118 displayed above the camera preview image 116 serves as a virtual viewfinder sight for the zoom field of view of the telephoto camera 108. When a user of the multi-camera device 102 moves the device and changes the camera scene and / or adjusts the focal length to zoom in or out of the telephoto lens, the user can quickly locate the target of the telephoto camera 108 from the zoom field of view shown in the area 120 of the camera scene relative to the wide field of view shown in the camera preview image 116.

[0023] Although described in this example as a single viewfinder user interface 112 displaying both a zoomed-out preview image 114 and a camera preview image 116, the zoomed-out preview image 114 and the camera preview image 116 can be displayed in separate viewfinder user interfaces and then simultaneously displayed on the display screen 110 of the multi-camera device 102. Furthermore, although the zoom field of view indicator 118 is displayed as a solid line (e.g., the outline of the border of region 120) in this example 100, the zoom field of view indicator 118 can be implemented as any type of solid line, dashed line, colored line, or other feature line or outline, and has any type of shading or highlight features to indicate region 120 of the camera scene, which indicates a zoomed field of view relative to a wide field of view.

[0024] In this example implementation, the viewfinder user interface 112 also includes a wide image capture icon 122 selectable by the user of the multi-camera device 102 to initiate the capture of a digital image in a wide field of view of the camera scene using the digital camera 106. The viewfinder user interface 112 also includes a zoom image capture icon 124 selectable by the user of the multi-camera device 102 to initiate the capture of digital content in a zoomed field of view of the camera scene using the telephoto camera 108. Furthermore, the user of the multi-camera device can select both the wide image capture icon 122 and the zoom image capture icon 124 approximately simultaneously to initiate both the capture of a digital image in a wide field of view of the camera scene using the digital camera 106 and the capture of digital content in a zoomed field of view of the camera scene using the telephoto camera 108.

[0025] Figure 2 This shows what can be used to achieve, such as reference Figure 1 An example 200 of a wireless device 202 of the telephoto camera viewfinder technology described herein is shown and described for a multi-camera device 102. In this example 200, the wireless device 202 can be any type of computing device, tablet device, mobile phone, flip phone, and / or any other type of mobile device. Typically, the wireless device 202 can be equipped with a processor system 204 to include an integrated or separate video graphics processor and memory 206, as described in references... Figure 5 The example device shown further describes any type of electronic and / or computing device implemented with various components of any number and combination of different components. For example, wireless device 202 may include a power source to power the device, such as a rechargeable battery and / or any other type of active or passive power source that can be implemented in electronic and / or computing devices.

[0026] In an implementation, wireless device 202 may be a mobile phone (also commonly referred to as a "smartphone") implemented as a multi-camera device. Wireless device 202 includes a digital camera 106 and a telephoto camera 108. Although the device is generally described herein as a multi-camera device with two cameras, any one or more devices may include more than two cameras. For example, implementations of wireless device 202 and / or multi-camera device 102 may include two or more separate cameras, such as those capturing digital content at different focal lengths and / or different apertures. As further illustrated in example 200, multi-camera device 102 includes a telescope attachment to enable telephoto camera 108 and allow zooming of the field of view, and includes a viewfinder scope 208 attached to the multi-camera device for viewing the unobstructed field of view of digital camera 106. Viewfinder scope 208 extends from the multi-camera device alongside the telescope attachment such that the telescope attachment does not obstruct the field of view of digital camera 106.

[0027] In this example 200, the digital camera 106 includes an imager 210 to capture digital images 212, such as digital photographs or digital video content. For example, the digital image 212 captured by the imager 210 of the digital camera 106 could be a digital photograph of an environment viewable using the digital camera, such as a digital image of a camera scene viewable in a wide field of view using the digital camera 106. The digital image 212 captured by the digital camera 106 of the wireless device 202 is an example of a camera preview image 116 that can be displayed in the viewfinder user interface 112 on the device's display screen 110.

[0028] Similarly, telephoto camera 108 includes an imager 214 to capture digital content 216, such as digital photographs or digital video content. For example, the digital content 216 captured by the imager 214 of telephoto camera 108 could be a digital photograph of the environment viewable using the telephoto camera, such as a digital image of a camera scene viewable in a zoomed-out field of view using telephoto camera 108. The digital content 216 captured by the telephoto camera 108 of wireless device 202 is an example of a zoomed-out preview image 114 that can be displayed in the viewfinder user interface 112 on the device's display screen 110.

[0029] In this example 200, as described herein and generally as referenced Figure 1As shown and described, the wireless device 202 includes an image viewfinder module 104 that implements the features of a telephoto camera viewfinder. The image viewfinder module 104 may be implemented as a module including independent processing, memory, and / or serving as a logical component of a computing and / or electronic device integrated with the wireless device 202. Alternatively or additionally, the image viewfinder module 104 may be implemented as a software application or software module, such as one integrated with an operating system, and as computer-executable software instructions executable by the processor of the wireless device 202 (e.g., via processor system 204). As a software application or module, the image viewfinder module 104 may be stored on a computer-readable storage memory (e.g., the device's memory 206), or in any other suitable storage device or in electronic data storage implemented by the image viewfinder module. Alternatively or additionally, the image viewfinder module 104 may be implemented as firmware and / or at least partially in computer hardware. For example, at least a portion of the image viewfinder module 104 may be executed by a computer processor, and / or at least a portion of the image viewfinder module may be implemented in logic circuitry.

[0030] In an implementation of a telephoto camera viewfinder, the image viewfinder module 104 can receive input and user selection, such as touch input 218 from a user of the wireless device 202 in the viewfinder user interface 112 on the device's display screen 110 (e.g., a touchscreen display). As described above, the viewfinder user interface 112 also includes a wide image capture icon 122 and a zoom image capture icon 124. The user of the wireless device 202 can select one of the image capture icons, such as a touch selection in the viewfinder user interface 112 on the device's display screen 110. The image viewfinder module 104 can then receive touch input 218 to initiate the digital camera 106 to capture a digital image 212 in a wide field of view of the camera scene in response to the touch input 218 as a selection of the wide image capture icon 122.

[0031] Alternatively, the image viewfinder module 104 can receive touch input 218 to initiate the capture of digital content 216 in a zoomed field of view of the camera scene by the telephoto camera 108 in response to the selection of the zoom image capture icon 124 by the touch input 218. Furthermore, the image viewfinder module 104 can receive touch input 218 as a user selection of both the wide image capture icon 122 and the zoom image capture icon 124 approximately simultaneously. The image viewfinder module 104 can then initiate both the capture of a digital image 212 in a wide field of view of the camera scene using the digital camera 106 and the capture of digital content 216 in a zoomed field of view of the camera scene using the telephoto camera 108.

[0032] In other embodiments, such as further reference Figure 3As shown and described, the image viewfinder module 104 can receive touch input 218 as a user selection in the viewfinder user interface 112 on the display screen 110 of the wireless device 202 relative to the border outline of region 120 (e.g., surrounded by zoom field of view indicator 118). For example, the image viewfinder module 104 can receive touch input 218 as touch selection 220 outside the border outline of region 120 (i.e., outside the zoom field of view indicator 118 on the camera preview image 116). Alternatively, the image viewfinder module 104 can receive touch input 218 as touch selection 222 within the border outline of region 120 (i.e., within the zoom field of view indicator 118 on the camera preview image 116).

[0033] In other embodiments, such as further reference Figure 3 As shown and described, the image viewfinder module 104 can receive touch input 218 as a user selection in the viewfinder user interface 112 on the display screen 110 of the wireless device 202 to adjust the size of the border outline of the region 120. For example, the image viewfinder module 104 can receive touch input 218 as a touch selection 224 to adjust the size of the border outline of the region 120, thereby effectively using the telephoto zoom control 226 to zoom out or further zoom in on the telephoto camera 108.

[0034] Figure 3 Example 300 illustrates features for a telephoto camera viewfinder using a multi-camera device 102 as described herein. As shown in example 302, a user of the multi-camera device 102 can touch selection 304 within the bounding contour of the area (e.g., within the zoom field of view indicator 118) on the device's display screen 110 to capture the viewfinder user interface 112. The image viewfinder module 104 can then receive the touch selection 222 within the bounding contour as touch input 218 and communicate control commands to initiate the telephoto camera 108 to capture digital content 216 within the zoom field of view of the camera scene. Similarly, as shown in example 306, a user of the multi-camera device 102 can touch selection 308 outside the bounding contour of the area (e.g., outside the zoom field of view indicator 118) on the device's display screen 110 to capture the viewfinder user interface 112. The image viewfinder module 104 can then receive the touch selection 220 outside the bounding contour as touch input 218 and communicate control commands to initiate the digital camera 106 to capture a digital image 212 within the wide field of view of the camera scene.

[0035] In other aspects of the telephoto camera viewfinder, the user of the multi-camera device 102 can adjust the size of the zoom field indicator 118 on the wide-field-of-view camera preview image 116 of the camera scene to effectively zoom out or further magnify the telephoto camera 108. For example, the user can touch and drag the corners or edges of the border outline of the selected area to decrease or increase the size of the border outline, which is displayed as a rectangle above the camera preview image 116. As the user decreases the size of the border outline, the telephoto camera 108 zooms out further, and as the user increases the size of the border outline, the telephoto camera 108 zooms out.

[0036] As shown in Example 310, a user of the multi-camera device 102 can touch the border outline of an area in the viewfinder user interface 112 above the camera preview image 116 and drag it across the display screen 110 in direction 314 to reduce the size of the zoom field of view indicator 118. The image viewfinder module 104 can receive the touch selection 224 for reducing the border outline of area 120 as touch input 218 and, in response to the reduction in the border outline size, transmit telephoto zoom control 226 to the telephoto camera 108 for further magnification. This also effectively changes the zoom preview image 114 displayed in the viewfinder user interface 112 with a further magnified zoom field of view, as shown in Example 310.

[0037] Similarly, as shown in Example 316, a user of the multi-camera device 102 can touch the border outline of an area in the viewfinder user interface 112 above the camera preview image 116 by touching selection 318 and dragging it across the display screen 110 in direction 320 to increase the size of the zoom field of view indicator 118. The image viewfinder module 104 can receive touch selection 224 as touch input 218 to increase the size of the border outline of area 120 and, in response to the increase in the size of the border outline, transmit telephoto zoom control 226 to the telephoto camera 108 to zoom out. This also effectively changes the zoomed preview image 114 displayed in the viewfinder user interface 112, which is a zoomed-out, altered zoom field of view as shown in Example 316.

[0038] Figure 4Additional example 400 of the features for a telephoto camera viewfinder using a multi-camera device 102 as described herein is shown. In addition to the viewfinder user interface 112 having both a wide image capture icon 122 and a zoom image capture icon 124 for the user to select to initiate capturing digital content in a wide field of view of the camera scene using the digital camera 106 and capturing digital content in a zoom field of view of the camera scene using the telephoto camera 108, the viewfinder user interface 112 includes an image capture icon 402 that is selectable and placeable anywhere within the viewfinder user interface. A user of the multi-camera device 102 can touch to select and drag to place the image capture icon 402 over the zoom preview image 114, over the camera preview image 116, or over a portion of both the zoom preview image 114 and the camera preview image 116.

[0039] As shown in Example 404, an image capture icon 402 is displayed at position 406 above the camera preview image 116, and a user of the multi-camera device 102 can touch to select the image capture icon 402 to initiate the capture of a digital image of the camera scene in a wide field of view using the digital camera 106. The image viewfinder module 104 can receive the selection of the image capture icon 402 as touch input 218 to initiate the capture of a digital image 212 by the digital camera 106 in response to the selection of the image capture icon. The image capture icon 402 is selectable to be placed above the display of the camera preview image 116, and a user can initiate the capture of a digital image 212 in a wide field of view using the digital camera 106 based on the position of the image capture icon above the display of the camera preview image 116. Alternatively, the image capture icon 402 can further be selectable to be placed above the display of the zoom preview image 114, and a user can initiate the capture of digital content 216 in a zoomed field of view of the camera scene using the telephoto camera 108 based on the position of the image capture icon above the display of the zoom preview image.

[0040] As shown in Example 408, a user of the multi-camera device 102 can select and drag the image capture icon 402 in the viewfinder user interface 112 across the display screen 110 in orientation 410 to reposition the image capture icon 402 above the zoomed preview image 114 at position 412. The user of the multi-camera device 102 can then touch to select the image capture icon 402 to initiate the capture of digital content in the zoomed field of view of the camera scene using the telephoto camera 108. The image viewfinder module 104 can receive the selection of the image capture icon 402 as touch input 218 to initiate the capture of digital content 216 by the telephoto camera 108 in response to the selection of the image capture icon.

[0041] It is worth noting that a user of the multi-camera device 102 can initiate a press-and-hold selection on the image capture icon 402 in the viewfinder user interface 112 to indicate that the image capture icon is moved to another position on the display. The user can then initiate another touch selection on the image capture icon 402 at the new display position in the viewfinder user interface 112 to initiate the capture of digital content using the camera. Alternatively, the image viewfinder module 104 can be implemented to recognize the press-and-hold selection on the image capture icon 402 when the image capture icon is moved to another position on the display, and release the image capture icon at the new display position to automatically initiate the capture of the corresponding digital content using the camera at the new position of the image capture icon.

[0042] As shown in Example 414, the image capture icon 402 can be repositioned by a user of the multi-camera device 102 in the viewfinder user interface 112, such as repositioning it to position 416 above at least a portion of both the zoom preview image 114 and the camera preview image 116. The user of the device can then touch to select the image capture icon 402 to initiate both capturing a digital image 212 in a wide field of view of the camera scene using the digital camera 106 and capturing digital content 216 in a zoomed field of view of the camera scene using the telephoto camera 108. The image viewfinder module 104 can receive the selection of the image capture icon 402 located above at least a portion of both the zoom preview image 114 and the camera preview image 116 as touch input 218 to initiate both the digital camera 106 capturing the digital image 212 and the telephoto camera 108 capturing the digital content 216 in response to the selection of the image capture icon at position 416.

[0043] Figure 5 Example 500 further illustrates features of a telephoto camera viewfinder using a multi-camera device 102 as described herein. In addition to displaying both a zoomed-out preview image 114 and a camera preview image 116 in the viewfinder user interface 112 on the display screen 110 of the multi-camera device, the viewfinder user interface 502 may include a wide field of view displayed as the camera preview image 116 captured by the digital camera 106. As shown in Example 504, a zoom field of view indicator 118 is also displayed in the viewfinder user interface 502 as a border outline of an area of ​​the camera scene above the camera preview image 116 to indicate a zoomed field of view relative to the wide field of view of the camera scene.

[0044] As shown in Example 506, a user of the multi-camera device 102 can touch selection 508 on the viewfinder user interface 502 of the device's display screen 110 within the border outline of the area (e.g., within the zoom field of view indicator 118). The image viewfinder module 104 can then receive the touch selection 222 within the border outline as touch input 218 and convey control commands to initiate the telephoto camera 108 to capture digital content 216 within the camera's zoom field of view. Similarly, as shown in Example 510, a user of the multi-camera device 102 can touch selection 512 on the viewfinder user interface 502 of the device's display screen 110 outside the border outline of the area (e.g., outside the zoom field of view indicator 118). The image viewfinder module 104 can then receive the touch selection 220 outside the border outline as touch input 218 and convey control commands to initiate the digital camera 106 to capture a digital image 212 within the camera's wide field of view.

[0045] Reference to the implementation method of telephoto camera viewfinder Figures 6 to 10 Example methods 600, 700, 800, 900, and 1000 are described. Generally, any services, components, modules, methods, and / or operations described herein can be implemented using software, firmware, hardware (e.g., fixed logic circuitry), manual processing, or any combination thereof. Some operations of the example methods may be described in the general context of executable instructions stored on computer-readable storage memory in local and / or remote computer processing systems, and implementations may include software applications, programs, functions, etc. Alternatively or additionally, any functionality described herein may be performed at least in part by one or more hardware logic components, such as, but not limited to, field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), application-specific standard products (ASSPs), system-on-a-chip (SoCs), complex programmable logic devices (CPLDs), etc.

[0046] Figure 6 An example method 600 for a telephoto camera viewfinder is shown, and is generally described with reference to multi-camera devices and image viewfinder modules implemented by those devices. The order in which the methods are described is not intended to be construed as limiting, and any number or combination of the method operations can be performed in any order to perform the method or alternative methods.

[0047] At 602, a digital image of the camera scene is captured as viewable using a digital camera in a wide field of view. For example, the digital camera 106 of the multi-camera device 102 includes an imager 210 to capture digital images 212, such as digital photographs or digital video content. The digital image 212 captured by the imager 210 of the digital camera 106 is a digital photograph of the environment viewable using the digital camera, such as a digital image of the camera scene viewable using the digital camera 106 in a wide field of view. The term "wide field of view" is "zoom field of view" relative to the telephoto camera 108, and typically has a narrower field of view compared to the wider field of view of the digital camera 106. The digital image 212 captured by the digital camera 106 of the multi-camera device 102 is an example of a camera preview image 116 that can be displayed in the viewfinder user interface 112 on the display screen 110 of the device.

[0048] At 604, digital content of the camera scene is captured as viewable in a zoomed field of view using a telephoto camera. For example, telephoto camera 108 includes an imager 214 to capture digital content 216, such as digital photographs or digital video content. The digital content 216 captured by the imager 214 of telephoto camera 108 is a digital photograph of the environment viewable using the telephoto camera, such as a digital image of the camera scene viewable in a zoomed field of view using telephoto camera 108. The term "zoomed field of view" is relative to the "wide field of view" of digital camera 106, and typically has a wider field of view compared to the narrower field of view of telephoto camera 108. The digital content 216 captured by the telephoto camera 108 of multi-camera device 102 is an example of a zoomed preview image 114 that can be displayed in the viewfinder user interface 112 on the display screen 110 of the device.

[0049] At 606, the displayed viewfinder user interface includes a zoomed field of view displayed as a zoomed preview image, and a wide field of view displayed as a camera preview image. For example, the display screen 110 of the multi-camera device 102 displays a viewfinder user interface 112, which includes a zoomed field of view displayed as a zoomed preview image 114 captured by the telephoto camera 108, and a wide field of view displayed as a camera preview image 116 captured by the digital camera 106.

[0050] At 608, a border outline of an area of ​​the camera scene indicating a zoomed field of view relative to the wide field of view of the camera scene is displayed above the camera preview image. For example, the viewfinder user interface 112 includes a display of a zoom field of view indicator 118, which is displayed in the viewfinder user interface above the camera preview image 116 to indicate a zoomed field of view relative to the wide field of view of the camera scene. The zoom field of view indicator 118 may be displayed above the camera preview image 116 as a border outline of an area 120 of the camera scene indicating a zoomed field of view relative to the wide field of view. It is worth noting that the area 120 of the camera scene corresponds to the zoomed preview image 114, which is also displayed in the viewfinder user interface 112.

[0051] Figure 7 An example method 700 for a telephoto camera viewfinder is shown, and is generally described with reference to multi-camera devices and image viewfinder modules implemented by those devices. The order in which the methods are described is not intended to be construed as limiting, and any number or combination of the method operations can be performed in any order to perform the method or alternative methods.

[0052] At 702, the displayed viewfinder user interface includes a zoomed field of view displayed as a zoomed preview image, and a wide field of view displayed as a camera preview image. For example, the display screen 110 of the multi-camera device 102 displays a viewfinder user interface 112, which includes a zoomed field of view displayed as a zoomed preview image 114 captured by the telephoto camera 108, and a wide field of view displayed as a camera preview image 116 captured by the digital camera 106.

[0053] At 704, a border outline of an area of ​​the camera scene indicating a zoomed field of view relative to the wide field of view of the camera scene is displayed above the camera preview image. For example, the viewfinder user interface 112 includes a display of a zoom field of view indicator 118, which is displayed in the viewfinder user interface above the camera preview image 116 to indicate a zoomed field of view relative to the wide field of view of the camera scene. The zoom field of view indicator 118 may be displayed above the camera preview image 116 as a border outline of an area 120 of the camera scene indicating a zoomed field of view relative to the wide field of view. It is worth noting that the area 120 of the camera scene corresponds to the zoomed preview image 114, which is also displayed in the viewfinder user interface 112.

[0054] At 706, touch selection input is received on the viewfinder user interface. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive input and user selection, such as touch input 218 by the user of the multi-camera device on the viewfinder user interface 112 of the device's display screen 110 (e.g., a touch screen display).

[0055] At 708, it is determined whether the input of a touch selection on the viewfinder user interface is within the border outline of the area indicating the zoom field of view. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive touch input 218 as touch selection 222 within the border outline of region 120 (i.e., within the zoom field of view indicator 118 on the camera preview image 116). As shown in Example 302, the image viewfinder module 104 can determine that the touch selection 304 in the viewfinder user interface 112 on the device's display screen 110 is within the border outline of the region (e.g., within the zoom field of view indicator 118).

[0056] If the touch selection input on the viewfinder user interface is within the bounding outline of the area indicating the zoom field of view (i.e., "Yes" at 708), then at 710, in response to the input, the telephoto camera captures digital content in the zoom field of view of the camera scene. For example, the image viewfinder module 104 may receive a touch selection 222 within the bounding outline as touch input 218 and, in response to the touch input, convey a control command to initiate the telephoto camera 108 to capture digital content 216 in the zoom field of view of the camera scene.

[0057] If the input of a touch selection on the viewfinder user interface is not within the border outline of the area indicating the zoom field of view (i.e., "No" at 708), then at 712, it is determined whether the input of the touch selection on the viewfinder user interface is outside the border outline of the area indicating the zoom field of view. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive touch input 218 outside the border outline of region 120 (i.e., outside the zoom field of view indicator 118 on the camera preview image 116) as touch selection 220. As shown in Example 306, the image viewfinder module 104 can determine that touch selection 308 in the viewfinder user interface 112 on the device's display screen 110 is outside the border outline of the region (e.g., outside the zoom field of view indicator 118).

[0058] If the touch selection input on the viewfinder user interface is outside the border outline of the area indicating zoom in / out (i.e., "Yes" at 712), then at 714, in response to the input, a digital image is captured in the wide field of view of the camera scene using the digital camera. For example, the image viewfinder module 104 may receive a touch selection 220 outside the border outline as touch input 218 and, in response to the touch input, convey control commands to initiate the digital camera 106 to capture a digital image 212 in the wide field of view of the camera scene.

[0059] If the input of the touch selection on the viewfinder user interface is not outside the border outline of the area indicating the zoom field of view (i.e., "No" at 712), the method continues to display the viewfinder user interface 112 at 702, which includes the zoom preview image 114 and the camera preview image 116, and the zoom field of view indicator 118 displayed above the camera preview image 116 to indicate the zoom field of view relative to the wide field of view of the camera scene.

[0060] Figure 8 An example method 800 for a telephoto camera viewfinder is shown, and is generally described with reference to multi-camera devices and image viewfinder modules implemented by those devices. The order in which the methods are described is not intended to be construed as limiting, and any number or combination of the method operations can be performed in any order to perform the method or alternative methods.

[0061] At 802, the viewfinder user interface includes a zoomed field of view displayed as a zoomed preview image, and a wide field of view displayed as a camera preview image. For example, the display screen 110 of the multi-camera device 102 displays a viewfinder user interface 112, which includes a zoomed field of view displayed as a zoomed preview image 114 captured by the telephoto camera 108, and a wide field of view displayed as a camera preview image 116 captured by the digital camera 106.

[0062] At 804, a border outline of an area of ​​the camera scene indicating a zoomed field of view relative to the wide field of view of the camera scene is displayed above the camera preview image. For example, the viewfinder user interface 112 includes a display of a zoom field of view indicator 118, which is displayed in the viewfinder user interface above the camera preview image 116 to indicate a zoomed field of view relative to the wide field of view of the camera scene. The zoom field of view indicator 118 may be displayed above the camera preview image 116 as a border outline of an area 120 of the camera scene indicating a zoomed field of view relative to the wide field of view. It is worth noting that the area 120 of the camera scene corresponds to the zoomed preview image 114, which is also displayed in the viewfinder user interface 112.

[0063] At 806, input is received in the viewfinder user interface to adjust the size of the border outline of the area indicating the zoomed field of view of the camera scene relative to the wide field of view. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive touch input 218 as a user selection in the viewfinder user interface 112 on the display screen 110 of the multi-camera device 102 to adjust the size of the border outline of the area 120. The image viewfinder module 104 can receive touch input 218 as a touch selection 224 to adjust the size of the border outline of the area 120 to effectively zoom out or further zoom in on the telephoto camera 108 using the telephoto zoom control 226.

[0064] At 808, it is determined whether to receive input in the viewfinder user interface to reduce the size of the border outline of the area of ​​the camera scene indicating the zoomed field of view relative to the wide field of view. For example, the image viewfinder module 104 implemented by the multi-camera device 102 may receive touch input 218 as touch selection 224 to reduce the size of the border outline of the area 120 of the camera scene.

[0065] If input is received in the viewfinder user interface to reduce the size of the border outline indicating the area of ​​the camera scene relative to the wide field of view (i.e., "Yes" at 808), then at 810, the telephoto camera is further magnified. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can transmit telephoto zoom control 226 to the telephoto camera 108 for further magnification in response to a reduction in the size of the border outline. This is also effective for changing the zoom preview image 114 displayed in the viewfinder user interface 112 corresponding to the changed zoom field of view corresponding to the reduction in the size of the border outline and the further magnification of the telephoto camera.

[0066] If no input from the viewfinder user interface is received to decrease the size of the border outline of the area of ​​the camera scene indicating the zoomed field of view relative to the wide field of view (i.e., "No" at 808), then at 812, it is determined whether input from the viewfinder user interface is received to increase the size of the border outline of the area of ​​the camera scene indicating the zoomed field of view relative to the wide field of view. For example, the image viewfinder module 104 implemented by the multi-camera device 102 may receive touch input 218 as touch selection 224 to increase the size of the border outline of the area 120 of the camera scene.

[0067] If input is received from the viewfinder user interface to increase the size of the border outline indicating the area of ​​the camera scene relative to the wide field of view (i.e., "Yes" at 812), then at 814, the telephoto camera is zoomed out. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can transmit telephoto zoom control 226 to the telephoto camera 108 to zoom out in response to an increase in the size of the border outline. This is also effective for changing the zoom preview image 114 displayed in the viewfinder user interface 112 corresponding to the change in the zoom field of view corresponding to the increase in the size of the border outline and the zooming out of the telephoto camera.

[0068] If no input is received from the viewfinder user interface to increase the size of the border outline of the area of ​​the camera scene indicating the zoomed field of view relative to the wide field of view (i.e., "No" at 812), the method continues to display the viewfinder user interface 112 at 802, which includes the zoomed preview image 114 and the camera preview image 116, and a zoomed field of view indicator 118 displayed above the camera preview image 116 to indicate the zoomed field of view relative to the wide field of view of the camera scene.

[0069] Figure 9 An example method 900 for a telephoto camera viewfinder is shown, and is generally described with reference to multi-camera devices and image viewfinder modules implemented by those devices. The order in which the methods are described is not intended to be construed as limiting, and any number or combination of the method operations can be performed in any order to perform the method or alternative methods.

[0070] At 902, the viewfinder user interface includes a zoomed field of view displayed as a zoomed preview image, and a wide field of view displayed as a camera preview image. For example, the display screen 110 of the multi-camera device 102 displays a viewfinder user interface 112, which includes a zoomed field of view displayed as a zoomed preview image 114 captured by the telephoto camera 108, and a wide field of view displayed as a camera preview image 116 captured by the digital camera 106. The viewfinder user interface 112 also includes a zoomed field of view indicator 118 displayed in the viewfinder user interface above the camera preview image 116 to indicate the zoomed field of view relative to the wide field of view of the camera scene.

[0071] At 904, selection input is received to place a capture icon in the viewfinder user interface. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive touch input 218 as a user touch selection and drag input in the viewfinder user interface 112 on the display screen 110 of the multi-camera device 102 to place the image capture icon 402 above the zoomed preview image 114, above the camera preview image 116, or above a portion of both the zoomed preview image 114 and the camera preview image 116. In this example, the viewfinder user interface 112 includes an image capture icon 402 that is selectable and placeable at any location within the viewfinder user interface.

[0072] At 906, a capture icon is displayed at a selected location in the viewfinder user interface. For example, the image capture icon 402 can be moved to a selected location in the viewfinder user interface 112, and displayed at a selected location above the zoomed preview image 114, above the camera preview image 116, or above a portion of both the zoomed preview image 114 and the camera preview image 116. At 908, input selection of the capture icon displayed in the viewfinder user interface is received. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive input selection of the image capture icon 402 displayed in the viewfinder user interface 112 as touch input 218.

[0073] At 910, it is determined whether the capture icon is displayed above at least a portion of both the zoomed preview image and the camera preview image displayed in the viewfinder user interface. For example, the image capture icon 402 may be placed in the viewfinder user interface 112 by the user of the multi-camera device 102, and the image viewfinder module 104 may determine the position 416 of the image capture icon 402 on at least a portion of both the zoomed preview image and the camera preview image.

[0074] If the capture icon is displayed above at least a portion of both the zoomed preview image and the camera preview image displayed in the viewfinder user interface (i.e., "Yes" at 910), then at 912, based on the position of the capture icon above at least a portion of both the zoomed preview image and the camera preview image displayed in the viewfinder user interface, a digital image is captured using the digital camera and digital content is captured using the telephoto camera. For example, the image viewfinder module 104 may receive an input selection of the image capture icon 402 placed above at least a portion of both the zoomed preview image 114 and the camera preview image 116 as touch input 218 to initiate the capture of digital image 212 by both the digital camera 106 and the capture of digital content 216 by both the telephoto camera 108 in response to the selection of the image capture icon at position 416.

[0075] If the capture icon is not displayed above at least a portion of both the zoomed preview image and the camera preview image shown in the viewfinder user interface (i.e., "No" at 910), then at 914, it is determined whether the capture icon is displayed above the camera preview image in the viewfinder user interface. For example, the image capture icon 402 may be placed in the viewfinder user interface 112 by the user of the multi-camera device 102, and the image viewfinder module 104 may determine the position 406 of the image capture icon 402 above the camera preview image 116.

[0076] If the capture icon is displayed above the camera preview image in the viewfinder user interface (i.e., "Yes" at position 914), then at position 916, based on the position of the capture icon above the camera preview image displayed in the viewfinder user interface, a digital image of the camera scene in a wide field of view is captured using the digital camera. For example, the image viewfinder module 104 may receive an input selection of the image capture icon 402 placed above the camera preview image 116 as touch input 218 to initiate the digital camera 106 to capture a digital image 212 of the camera scene in a wide field of view in response to the selection of the image capture icon at position 416.

[0077] If the capture icon is not displayed above the camera preview image in the viewfinder user interface (i.e., "No" at 914), then at 918, it is determined whether the capture icon is displayed above the zoomed preview image in the viewfinder user interface. For example, the image capture icon 402 may be placed in the viewfinder user interface 112 by the user of the multi-camera device 102, and the image viewfinder module 104 may determine the position 412 of the image capture icon 402 above the zoomed preview image 114.

[0078] If the capture icon is displayed above the zoomed-out preview image in the viewfinder user interface (i.e., "Yes" at 918), then at 920, the telephoto camera captures digital content in the zoomed-out field of view of the camera scene based on the position of the capture icon above the zoomed-out preview image displayed in the viewfinder user interface. For example, the image viewfinder module 104 may receive an input selection of the image capture icon 402 placed above the zoomed-out preview image 114 as touch input 218 to initiate the telephoto camera 108 to capture digital content 216 in the zoomed-out field of view of the camera scene in response to the selection of the image capture icon at position 412.

[0079] If the capture icon is not displayed above the zoomed preview image in the viewfinder user interface (i.e., "No" at 918), the method continues to display the viewfinder user interface 112 at 902, which includes the zoomed preview image 114 and the camera preview image 116, and a zoom field of view indicator 118 displayed above the camera preview image 116 indicating the zoom field of view relative to the wide field of view of the camera scene.

[0080] Figure 10 An example method 1000 for a telephoto camera viewfinder is shown, and is generally described with reference to multi-camera devices and image viewfinder modules implemented by those devices. The order in which the methods are described is not intended to be construed as limiting, and any number or combination of the method operations can be performed in any order to perform the method or alternative methods.

[0081] At 1002, a digital image of the camera scene is captured as viewable in a wide field of view using a digital camera. For example, the digital camera 106 of the multi-camera device 102 includes an imager 210 to capture digital images 212, such as digital photographs or digital video content. The digital image 212 captured by the imager 210 of the digital camera 106 is a digital photograph of an environment viewable using a digital camera, such as a digital image of a camera scene viewable in a wide field of view using the digital camera 106. The term "wide field of view" is "zoom field of view" relative to the telephoto camera 108, and typically has a narrower field of view compared to the wider field of view of the digital camera 106. The digital image 212 captured by the digital camera 106 of the multi-camera device 102 is an example of a camera preview image 116 that can be displayed in the viewfinder user interface 502 on the display screen 110 of the device.

[0082] At 1004, digital content of the camera scene is captured as viewable in a zoomed field of view using a telephoto camera. For example, telephoto camera 108 includes an imager 214 to capture digital content 216, such as digital photographs or digital video content. The digital content 216 captured by the imager 214 of telephoto camera 108 is a digital photograph of the environment viewable using the telephoto camera, such as a digital image of the camera scene viewable in a zoomed field of view using telephoto camera 108. The term "zoomed field of view" is relative to the "wide field of view" of digital camera 106, and typically has a wider field of view compared to the narrower field of view of telephoto camera 108.

[0083] At 1006, the displayed viewfinder user interface includes a wide field of view displayed as a camera preview image captured by the digital camera. For example, the display screen 110 of the multi-camera device 102 displays a viewfinder user interface 502 including a wide field of view displayed as a camera preview image 116 captured by the digital camera 106.

[0084] At 1008, a border outline of an area of ​​the camera scene indicating a zoomed field of view relative to the wide field of view of the camera scene is displayed above the camera preview image. For example, the viewfinder user interface 502 includes a display of a zoom field of view indicator 118, which is displayed in the viewfinder user interface above the camera preview image 116 to indicate a zoomed field of view relative to the wide field of view of the camera scene. The zoom field of view indicator 118 may be displayed above the camera preview image 116 as a border outline of the area 120 of the camera scene indicating a zoomed field of view relative to the wide field of view.

[0085] At 1010, touch selection input is received on the viewfinder user interface. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive input and user selection, such as touch input 218 by the user of the multi-camera device on the viewfinder user interface 502 of the device's display screen 110 (e.g., a touch screen display).

[0086] At 1012, it is determined whether the input of a touch selection on the viewfinder user interface is within the border outline of the area indicating the zoom field of view. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive touch input 218 as touch selection 222 within the border outline of region 120 (i.e., within the zoom field of view indicator 118 on the camera preview image 116). As shown in Example 506, the image viewfinder module 104 can determine that the touch selection 508 in the viewfinder user interface 502 on the device's display screen 110 is within the border outline of the region (e.g., within the zoom field of view indicator 118).

[0087] If the touch selection input on the viewfinder user interface is within the bounding outline of the area indicating the zoom field of view (i.e., "Yes" at 1012), then at 1014, in response to the input, the telephoto camera captures digital content in the zoom field of view of the camera scene. For example, the image viewfinder module 104 may receive touch selection 222 within the bounding outline as touch input 218 and, in response to the touch input, convey control commands to initiate the telephoto camera 108 to capture digital content 216 in the zoom field of view of the camera scene.

[0088] If the input of a touch selection on the viewfinder user interface is not within the border outline of the area indicating the zoom field of view (i.e., "No" at 1012), then at 1016, it is determined whether the input of the touch selection on the viewfinder user interface is outside the border outline of the area indicating the zoom field of view. For example, the image viewfinder module 104 implemented by the multi-camera device 102 can receive touch input 218 outside the border outline of region 120 (i.e., outside the zoom field of view indicator 118 on the camera preview image 116) as touch selection 220. As shown in Example 510, the image viewfinder module 104 can determine that touch selection 512 in the viewfinder user interface 112 on the device's display screen 110 is outside the border outline of the region (e.g., outside the zoom field of view indicator 118).

[0089] If the touch selection input on the viewfinder user interface is outside the bounding box of the area indicating zoom in / out (i.e., "Yes" at 1016), then at 1018, in response to the input, a digital image is captured in the wide field of view of the camera scene using the digital camera.
