Fig. 1 is a flowchart of a video recording method according to an embodiment.
The invention provides a video recording method, which is applied to a mobile terminal and comprises the following steps of S100-S300:
step S100: the method comprises the steps of recording a video when a recording instruction input by a user is received, then pausing the recording when a pause instruction input by the user is received, acquiring and storing first posture data acquired by a posture sensor at the current moment, and then generating a first video file. In some embodiments, the first video file may be a cache file recorded in the memory.
In consideration of the fact that users can shoot and record more conveniently, the same key can be used for inputting a recording instruction, a pause instruction, a subsequent continuous recording instruction and a subsequent stop instruction, and key multiplexing is achieved. The keys may be virtual keys or physical keys. The following are specific examples of 2:
example 1: the user can send a recording instruction or a recording continuing instruction by long-pressing the recording key to record the video, and the terminal continuously records the video in the process of identifying the long-pressing of the user; when the fact that the finger of the user is lifted up and leaves the recording key is recognized, the terminal judges that the user inputs a pause instruction or a stop instruction, and therefore recording is immediately paused or stopped.
Example 2: the user can click the recording key to send a recording instruction, the terminal starts to record the video, and in the recording process, the user clicks the recording key again to send a pause instruction, and the terminal pauses the recording; and when the user clicks the recording key again to send a continuous recording instruction, the terminal continues recording the video, and in the recording process, the user clicks the recording key last time to send a stop instruction, the terminal stops recording, and the video recording is completed.
In some embodiments, the video is recorded immediately upon receiving the recording command input by the user, while in other embodiments, the video is recorded after a first predetermined time, for example 3 seconds, has elapsed after receiving the recording command input by the user.
When the video is shot, a shooting progress part with a time mark can be displayed, for example, a shooting progress bar is displayed, and the shooting progress is displayed in real time. The recording progress bar is provided with a time mark so that a user can know the recording time of the video conveniently. When the recording is paused when a pause instruction input by a user is received, the recording progress bar is paused synchronously.
Of course, the recording of the video may be paused and resumed many times, which is not described herein.
The attitude sensor includes an angular velocity sensor (gyroscope) or includes a magnetic sensor, or includes both an angular velocity sensor and a magnetic sensor. The angular velocity sensor can determine the tilt posture of the terminal, and the magnetic sensor can determine the orientation posture of the terminal. The tilt posture is mainly determined by the lateral tilt angle and the longitudinal tilt angle of the terminal, and the orientation posture is determined by the orientation of the terminal, for example, two directions of the long side of the terminal may be set as the longitudinal direction, two directions of the wide side may be set as the lateral direction, and the direction of one end of the long side of the terminal may be set as the terminal orientation. Accordingly, the first posture data may include data reflecting the current posture of the terminal, such as a lateral tilt angle, a longitudinal tilt angle, and a terminal orientation of the terminal.
Magnetic sensors are widely used in modern industry and electronic products to sense magnetic field strength to measure physical parameters such as current, position, direction, etc. In the prior art, there are many different types of sensors for measuring magnetic fields. For example, a magnetic sensor using a Hall (Hall) element, an Anisotropic Magnetoresistive (AMR) element, or a Giant Magnetoresistive (GMR) element as a sensitive element. Tmr (tunnel magnetoresistive resistance) elements are a new magnetoresistive effect sensor which has started to be industrially used in recent years, which senses a magnetic field by using the tunnel magnetoresistive effect of a magnetic multilayer film material, and has a larger rate of change in resistance than the AMR element and the GMR element which have been found and put into practical use before.
In order to facilitate the user to re-record the recorded video when the recorded video is not satisfactory, in some embodiments, after the first video file is generated, the video can be re-recorded and the first video file can be re-generated when a re-recording instruction input by the user is received (for example, the user clicks a re-recording button), and the old first video file is deleted or replaced by the re-generated first video file.
In other embodiments, after the first video file is generated, the first video file may be deleted after receiving a deletion instruction input by the user (e.g., the user clicks a delete button), and then the video may be re-recorded and the first video file may be regenerated when a re-recording instruction input by the user is received (e.g., the user clicks a record button again).
In some embodiments, an instruction of a user can be further received to add animation special effect content to the first video file so as to increase the interestingness of the video.
After the first video file is generated, step S200 is executed.
Step S200: and sending a corresponding prompt for adjusting the terminal posture to the user according to the matching relation between the first posture data and the second posture data detected by the posture sensor in real time.
After the first video file is generated, when the user adjusts the starting posture of the recorded next video before recording, the posture sensor detects and collects second posture data reflecting the real-time posture of the terminal in real time, then the terminal can send a prompt for adjusting the posture of the terminal to the user according to the matching relation between the first posture data and the second posture data, and the prompt for adjusting the posture of the terminal comprises an image prompt and/or a voice prompt for indicating the user to adjust the transverse inclination angle and the longitudinal inclination angle of the terminal or adjust the orientation angle of the terminal.
When the gesture of the user holding the terminal does not match the gesture of the user at the moment of pause recording, the current dynamic picture and the last frame picture are not matched naturally, so that by comparing the first gesture data with the second gesture data, the matching degree or similarity (which can be determined by comparing the difference value or the ratio between the first gesture data and the second gesture data) between the current gesture of the terminal and the gesture of the terminal at the moment of pause can be analyzed, so that the user can be prompted to make a corresponding adjustment action, for example, the user is prompted to tilt or incline towards a certain direction (forward, backward, leftward, rightward), or the user is prompted to adjust the terminal to a certain direction (east, west, south, north) by how many angles, or the user is directly instructed to rotate the terminal clockwise or counterclockwise by how many angles. When the first posture data and the second posture data are compared to judge that the current posture of the terminal is matched with or similar to the posture of the terminal in the pause process, the user can be prompted to continue recording.
For the image prompt, a transverse indication bar and a longitudinal indication bar can be arranged when the terminal is displayed, the transverse indication bar is provided with a transverse floating point, the longitudinal indication bar is provided with a longitudinal floating point, the transverse floating point moves in the transverse indication bar according to the posture adjustment of the terminal, the longitudinal floating point moves in the longitudinal indication bar according to the posture adjustment of the terminal, namely the transverse floating point and the longitudinal floating point move transversely or longitudinally according to the data acquired by the posture sensor in real time. The gesture determined with the first gesture data is a standard gesture in which the horizontal floating point is at a standard position (e.g., a middle point) of the horizontal indicator bar and the vertical floating point is at a standard position (e.g., a middle point) of the vertical indicator bar. Therefore, when the second posture data detected by the posture sensor in real time does not match with the first posture data, the horizontal floating point and the vertical floating point are naturally not in the standard positions, and the user can achieve the purpose of posture adjustment by adjusting the terminal posture so that the horizontal floating point and the vertical floating point reach the standard positions. Referring to fig. 2, fig. 2 is a schematic diagram of an image prompt for adjusting a terminal posture according to an embodiment, where the vertical floating point needs to be moved down to a standard position, and the vertical floating point needs to be moved left to a standard position, so that a user can tilt the terminal up and down to adjust the vertical floating point, and can tilt the terminal left and right to adjust the horizontal floating point.
Still alternatively, a standard position may be set and an activity floating point may be set, the activity floating point being active in a specified area (e.g., a circular area) according to the adjustment of the posture of the terminal, the standard position being at the center (e.g., the center of a circle) within the specified area. When the second posture data detected by the posture sensor in real time is not matched with the first posture data, the activity floating point is naturally not at the standard position, and the user can adjust the posture by adjusting the terminal posture to enable the activity floating point to reach the standard position. Referring to fig. 3, fig. 3 is a schematic diagram of an image prompt for adjusting a terminal posture according to another embodiment, where the activity floating point needs to be moved to a standard position from a lower right corner, so that a user can tilt the terminal up and down, left and right to adjust the activity floating point.
The image prompt can be displayed at a designated position of a terminal screen, for example, a small area in the middle of the screen, and the shooting preview is not affected. In some embodiments, when the first posture data and the second posture data match or are similar (which may be determined by determining whether a difference or a ratio between the first posture data and the second posture data is within a preset threshold), the image prompt may disappear to avoid affecting the video preview; when the first gesture data and the second gesture data do not match or are similar again, the image cues described above reappear to facilitate the user to adjust again.
Step S300: and continuing to record the video when receiving a recording continuation instruction input by the user (for example, the user clicks the recording button again), and then stopping recording when receiving a stopping instruction input by the user and generating a second video file. In some embodiments, the second video file may be a cache file recorded in the memory.
In some embodiments, the video is recorded immediately upon receiving the user-input resume command, while in other embodiments, the video is recorded after a second predetermined time, for example 3 seconds, has elapsed after receiving the user-input resume command. During video recording, a recording progress part with a time mark can be displayed, for example, a recording progress bar is displayed, and the recording progress is displayed in real time.
Also, for convenience, after the second video file is generated, when a user clicks a re-recording button, the video may be re-recorded and the second video file may be re-generated, and the old second video file may be deleted or replaced by the re-generated second video file.
In other embodiments, after the second video file is generated, the second video file may be deleted after receiving a deletion instruction input by the user (e.g., the user clicks a delete button), and then the video may be re-recorded and the second video file may be regenerated when a re-recording instruction input by the user is received (e.g., the user clicks a record button again).
In some embodiments, an instruction of the user may be further received to add animation special effect content to the second video file, so as to increase the interest of the video.
Step S400: and splicing the first video file and the second video file into a target video file. The target video file may also be a cache file in a memory, and when a sharing instruction or a storage instruction input by a user is received, the target video file is shared, or stored locally, or stored in a cloud server. The first video file and the second video file may be spliced into the target video file after receiving a splicing instruction input by the user, or the first video file and the second video file may be automatically spliced into the target video file after step S300, without limitation.
Of course, after the target video file is generated, image processing may be performed on the target video file, for example, an animated special effect may be added. Image signal processing includes, but is not limited to, at least one of the following: black subtraction, lens roll-off correction, channel gain adjustment, bad pixel correction, demosaicing, cropping, scaling, white balance, color correction, luma adaptation, color conversion, and image contrast enhancement.
Still alternatively, in order to enable the content of the first video or the second video of the target video file to be faster or slower during playing, in some embodiments, before the first video file and the second video file are spliced into the target video file, the first video file and/or the second video file may be subjected to frame insertion processing or frame extraction processing. The frame interpolation process may be to interpolate a repeated frame between frames of the video, and the time length of the video is increased accordingly, and the motion is slowed down as viewed by the user. While the frame extraction process may be to extract and discard some frames of the video frames uniformly (e.g., to extract odd or even frames), the time duration of the video is reduced accordingly, and the action is faster as viewed by the user.
Of course, there may be a situation where multiple video files are temporarily and continuously recorded and then generated, and in such a situation, the multiple video files need to be spliced, which is not described herein.
The present invention also provides a video recording terminal, comprising: a display; one or more processors; a memory; one or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the one or more processors, the one or more programs configured to: a video recording method according to any of the above embodiments is performed.
