[0021] To make the objectives, technical solutions, and advantages of this disclosure clearer, various embodiments are described in detail below with reference to the accompanying drawings. Unless otherwise stated, the embodiments and features described herein can be combined with each other.

[0022] This document uses chapter headings, including appendices, to improve readability and does not in any way limit the discussion to individual chapters. Furthermore, the term "video" is used throughout for brevity; it can be understood that the described techniques are applicable to capturing and storing video (a sequence of images) or a single picture or image. Additionally, for ease of description, the terms "telephone," "mobile phone," or "cell phone" are used to describe a variety of different handheld devices, including those with cameras. Such devices include handheld tablets, tablets, laptops, e-book readers, etc.

[0023] Most handheld electronic devices are rectangular—meaning they are longer in one dimension than the other. For example, most mobile phones and tablets are rectangular. When a user holds such a device with the longer dimension in a vertical orientation, this orientation is called "portrait mode." Similarly, when a user holds the device with the longer dimension in a horizontal orientation, this is sometimes referred to as "landscape mode" operation.

[0024] Users typically hold their phones in portrait mode to make calls, send text messages, and record videos. While portrait mode is easier to grip, when recording video in portrait mode, over 50% of the action in the field of view is not captured (see reference). Figure 5 (And Figure 6). In longitudinal video, only the center of the viewing area is shown or filmed. Whether it's for entertainment, special occasions, eyewitness accounts of events, or eyewitness accounts of ongoing criminal activities, what's lacking is the surrounding action from a wider angle that can add more detail to the event.

[0025] Holding the phone in portrait mode offers at least the following advantages. First, it improves operational efficiency by enabling one-handed operation, using the thumb for keystroke input in navigation, making calls, texting, and taking photos / videos. Second, it provides a higher, more advantageous position when holding the phone for photo / video shooting. Third, it is less likely for the camera to be obstructed by the user's fingers. On a beneficial side, the technology disclosed herein facilitates wide-angle video shooting in common phone-holding postures and allows for video shooting in landscape mode.

[0026] Figure 1 An example of a mobile phone with its portrait orientation facing down is shown. This phone is equipped with two cameras, each including a lens section. The phone also includes a flash for providing illumination during video recording. For example, this flash could be a light-emitting diode (LED).

[0027] The two front-facing cameras on a mobile phone typically have the same pixel resolution for image capture. Furthermore, these two cameras are usually designed to capture images with the same aspect ratio. A phone may be equipped with a horizontally oriented image sensor 1 and a vertically oriented image sensor 2 (see reference). Figure 1 and Figure 3 ).

[0028] Figure 1 An example of a mobile phone in portrait mode is shown. Two camera lenses, an LED flash, and two integrated circuits for capturing and storing images are shown. In some embodiments, only one image sensor can be active during shooting, depending on the phone's orientation. For example, image sensor 1 can be activated for landscape shooting, and image sensor 2 can be activated for portrait mode shooting.

[0029] Figure 2 Showing landscape mode Figure 1 The diagram shows the operation of a mobile phone. Here, image sensor 2 is on, and image sensor 1 is off.

[0030] When the phone is held in portrait mode and video recording is enabled, the phone's accelerometer or screen orientation sensor (not explicitly shown in the accompanying drawings) is activated to open camera 1 and close camera 2. The resulting video is in landscape mode. In some embodiments, the phone's accelerometer or screen orientation sensor can be advantageously implemented on the long edge of the phone to improve orientation accuracy. In some embodiments, two (or more) physically separate phone accelerometer or screen orientation sensor assemblies can be used, one placed along the long edge of the phone and the other along the short edge, and signals from these multiple sensors can be averaged or linearly weighted to obtain an accurate measurement of the phone's orientation.

[0031] When camera 1 is recording, if the user rotates the phone to landscape mode, the phone turns off camera 1 and turns on camera 2 upon detecting the mode change. It can be advantageous to synchronize the transition from recording with camera 1 to recording with camera 2 with the camera's rotation speed and the frame rate per second (fps) shooting speed. In some embodiments, a memory window can be used to account for frequent phone rotations. For example, if the phone rotates between landscape and portrait modes and then rotates back to its original mode within a specified time window (e.g., 1 second), such rotations can be ignored, and no change in recording mode is performed due to such brief rotations.

[0032] At the end of the video recording session, the phone generates two landscape video clips, one from camera 1 and the other from camera 2. The phone can now combine these two video clips with the same resolution and aspect ratio to create a complete and seamless landscape video file.

[0033] By default, the phone can start recording video in landscape mode. The same default landscape mode can be applied to photo shooting. Users can change it to portrait mode for a specific time period via a selection screen icon, or change it back to the default portrait mode setting at startup in the camera settings.

[0034] If the phone is held in portrait mode and video is being recorded for the entire duration, the resulting video clip taken by camera 1 will be in landscape mode, requiring no further orientation reprocessing.

[0035] If the phone is held in landscape mode and video is recorded for the entire duration, the resulting video clip from camera 2 will be in landscape mode, requiring no further orientation adjustments.

[0036] In some embodiments, integrated circuit 1 and integrated circuit 2 may be functionally identical. Both may have the same horizontal and vertical pixel resolution, as well as the same aspect ratio. The orientation of the phone, portrait or landscape, can be determined by the phone's accelerometer. The top side of the image sensor can also be determined by the accelerometer. When multiple video clips are captured in a time period, alternating between portrait and landscape modes (and vice versa), the video clips captured by cameras 1 and 2 can be combined chronologically with matching top sides. The resulting combined video clip shows the complete video in landscape mode. For example, without matching top sides of the image sensor, the resulting combined video clip would show a combination of a video with the right side facing up and a video reversed vertically.

[0037] In some embodiments, integrated circuit 1 may be mounted at a 90-degree angle relative to integrated circuit 2. Therefore, image sensor 1 is rotated 90 degrees relative to image sensor 2 (see reference). Figure 1 and Figure 2 ).

[0038] When the phone is held in portrait mode and aimed at a subject, the user can take a landscape or portrait photo by selecting a designated screen icon without rotating the phone. Taking a photo involves selecting camera 1 for landscape or camera 2 for portrait. The photo mode may depend on the user's last usage. If the last usage was landscape, the phone will open in landscape mode. If the last usage was portrait mode, the phone will open in portrait mode.

[0039] Figure 3 An example of an icon displayed on a user's device during video recording is shown. By interacting with this icon, a user can change the shooting orientation without physically changing the camera's orientation. For example, touching the icon during video recording changes the shooting orientation without interrupting the recording. Alternatively or additionally, in some embodiments, the icon can be continuously touched to temporarily change the shooting orientation, and releasing the touch returns the shooting orientation to its original orientation.

[0040] Figure 4 This shows another example of the icons for video shooting in portrait mode. Here, the video currently being shot in portrait mode can be redirected to landscape mode by selecting the icon.

[0041] Figure 5The example shown (top left) illustrates the limitations of displaying portrait video in landscape mode, resulting in the lack of footage of the surrounding scenery in the field of view. In contrast, in landscape mode (bottom right), the additional landscape scenery is being captured and displayed in the video.

[0042] Figures 6A-6B A flowchart illustrating the camera operation method is shown. Initially, a video recording mode can be selected for the phone. If the user has preset portrait mode, the system checks if the phone is currently being held in portrait mode. If so, Camera 2 is opened, Camera 1 is closed, and video recording is started or resumed. Otherwise, if not, Camera 1 is opened, Camera 2 is closed, and video recording is started or resumed. Both operations further display the video.

[0043] During the video recording operation, a continuous check is performed to ensure that the phone is being held in portrait mode.

[0044] If it is determined that the user has not preset portrait mode, then it checks whether the phone is currently in portrait mode. If so, it opens Camera 1, closes Camera 2, and starts or begins video recording. If not, it opens Camera 2, closes Camera 1, and starts or begins video recording. The camera can be closed after the video recording period ends. Otherwise, the process of determining portrait mode will continue.

[0045] In the above description, camera 1 corresponds to the horizontal mode shooting camera, and camera 2 corresponds to the vertical mode operation camera.

[0046] like Figure 6B As shown, depending on whether the phone's orientation was changed during the video recording period, video editing can be performed to combine video files from camera 1 and camera 2 in chronological order to generate a seamless video file with the same orientation throughout. Otherwise, no editing is required, and the recorded video will be stored in the recording device's memory.

[0047] Figure 7 An example method 700 for camera operation is shown. For example, camera operation can be performed by an electronic device including camera 1 and camera 2, as shown in reference... Figure 1 and Figure 2 As stated above.

[0048] Method 700 includes determining (702) the shooting orientation mode setting of the shooting device for video shooting. For example, the shooting orientation mode may be a portrait mode or a landscape mode.

[0049] Method 700 includes capturing (704) video using either a first camera or a second camera based on the shooting orientation mode and current orientation of the shooting device, wherein the video can be captured in the shooting orientation mode. (See reference...) Figures 1-4The current orientation of the shooting device can be either vertical or horizontal.

[0050] Method 700 includes storing (706) the video in a video file after shooting.

[0051] In some embodiments, if the shooting orientation mode is landscape mode and the current orientation is landscape, then a second camera is used to perform the shooting.

[0052] In some embodiments, if the shooting orientation mode is horizontal and the current orientation is vertical, the first camera is used to perform the shooting.

[0053] In some embodiments, if the shooting orientation mode is portrait mode and the current orientation is lateral, the first camera is used to perform the shooting.

[0054] In some embodiments, if the shooting orientation mode is portrait mode and the current orientation is portrait orientation, then a second camera is used to perform the shooting.

[0055] The method may also include receiving input on the user interface of the shooting device to change the shooting orientation mode; and changing the shooting orientation mode based on the input without changing the current orientation of the shooting device.

[0056] In some embodiments, the video includes a first portion captured using a first camera and a second portion captured using a second camera, and storing the video file includes processing the video file by combining the first portion and the second portion in chronological order.

[0057] In some embodiments, the current orientation of the shooting device is continuously monitored during shooting.

[0058] Figure 8 An example video recording device 800 is shown. Device 800 includes a first camera configured to record landscape mode video and a second camera configured to record portrait mode video (reference numeral 808). Device 800 includes an orientation sensor 806 configured to detect the current orientation of the video recording device. Device 800 includes a user interface 810. Device 800 includes a processor 802 configured to: receive a shooting orientation mode setting; control a video recording period using either the first or second camera based on the shooting orientation mode and the current orientation of the recording device; and store the video in a memory associated with the video recording device.

[0059] In some embodiments, the shooting orientation mode is either a portrait mode or a landscape mode.

[0060] In some embodiments, the current orientation of the video recording device is either longitudinal or lateral.

[0061] In some embodiments, if the shooting orientation mode is landscape mode and the current orientation is landscape, then a second camera is used to perform the shooting.

[0062] In some embodiments, if the shooting orientation mode is horizontal and the current orientation is vertical, the first camera is used to perform the shooting.

[0063] In some embodiments, if the shooting orientation mode is portrait mode and the current orientation is lateral, the first camera is used to perform the shooting.

[0064] In some embodiments, if the shooting orientation mode is portrait mode and the current orientation is portrait orientation, then a second camera is used to perform the shooting.

[0065] In some embodiments, the processor is further configured to: receive input on a user interface to change the shooting orientation mode; and change the shooting orientation mode based on the input without changing the current orientation of the shooting device.

[0066] In some embodiments, the video includes a first portion captured using a first camera and a second portion captured using a second camera, and storing the video file includes processing the video file by a processor combining the first and second portions in chronological order. The video file may be stored in the memory 804 of the device 800. The memory 804 may also be used to store program instructions, metadata, and other useful information for operating the device 800.

[0067] In some embodiments, the current orientation of the video recording device is continuously monitored during recording.

[0068] In some embodiments, the video recording device is a mobile phone.

[0069] In some embodiments, the video recording device is a tablet device.

[0070] In some implementations, method 700 can operate to allow a user of the electronic device to seamlessly change the shooting orientation mode to match the current orientation of the shooting device. This can be achieved by allowing the user to make a choice on the user interface to maintain the current orientation mode. For example, such a setting can be used when a user is shooting video in landscape mode and then notices something of interest above it and wants to capture details in the vertical direction simply by tilting the electronic device from landscape to portrait. In this example, markers can be introduced into the shot video so that the resulting video file can include segments of video that were in different orientations in the same time sequence as the user tilted the electronic device. In some embodiments, the processor can generate metadata information associated with the shot video (e.g., each frame of the video) by writing the device orientation and shooting mode of the device at the time of shooting. This metadata information can be used to stitch the shot video files together to have the correct intended playback orientation.

[0071] The foregoing description also applies to user-facing cameras. Users can hold the phone in portrait mode and select via on-screen icons (see...). Figure 4 Take selfies or selfie videos in landscape or portrait mode without rotating your phone.

[0072] In some embodiments, during the recording process, the orientation of the video recording device subsequently changes from portrait to landscape (or vice versa). For example, if the video recording device is tilted by 10 degrees or more, a processor that receives data from an accelerometer marks each tilted video frame and provides the user with the option to retain or delete the marked video frames.

[0073] In some embodiments, the threshold for the accelerometer to change from longitudinal to lateral mode (and vice versa) is approximately 45 degrees (e.g., due to actual hardware implementation, the tolerance is 45 degrees plus or minus 1 degree).

[0074] The implementation can use one of two types of accelerometers, analog or digital. Analog accelerometers output a continuous voltage proportional to acceleration. Digital accelerometers, on the other hand, can use pulse width modulation (PWM) as their output, meaning there is a square wave of a certain frequency, and the amount of time the high voltage is proportional to the acceleration or tilt angle. The processor of the video recording device can measure the duration of the logic high level to determine the angle and mark each video frame as the phone tilts towards a mode change.

[0075] For continuous rotation in shooting mode, the processor can notify the user via a message on the screen that "shooting is in progress, prepare to switch cameras" so that the user is aware that the final output video will have a negative impact on the viewing experience.

[0076] In some embodiments, 3D shooting and viewing can be performed on a mobile phone screen without the use of 3D viewing glasses (glasses-free 3D). For 3D shooting, there can be four front-facing cameras. Two are mounted in the upper left corner and two in the upper right corner to simulate binocular vision, thereby generating depth perception. The camera sensors in the upper left and upper right corners can be oriented horizontally. The camera sensors below the upper left and upper right corners are oriented vertically. The resulting video will have two video files. One from camera 1L and / or 2L, and the other from camera 1R and / or 2R. The processor will alternately display the L and R videos at a high frame rate, synchronized with active L and R pixel filters (not yet invented) layered on the display below the capacitive touchscreen layer. The L pixel filter is activated when the L video is displayed, and the R pixel filter is activated when the R video is displayed. The width of the 3D viewing angle depends on the design of the active pixel filters. Therefore, the currently disclosed technology can also be applied to mode management in 3D video shooting.

[0077] The disclosed and other embodiments, modules, and functional operations described herein can be implemented in digital electronic circuits or in computer software, firmware, or hardware, including the structures disclosed herein and their equivalents, or combinations thereof. The disclosed and other embodiments can be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a computer-readable medium for execution by or control of the operation of a data processing apparatus.
