The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, mobile terminal 100 may include two or more display units (or other display devices), for example, mobile terminal 100 may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.
The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like.

For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (communicating communication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.
The memory 160 may store software programs or the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, etc.) that has been output or is to be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

Each BS 270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS 270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz, 5MHz, etc.).
The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each partition of a particular BS 270 may be referred to as a plurality of cell sites.
As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several satellites 300 are shown, for example, Global Positioning System (GPS) satellites 300 may be employed. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.
In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal 100 may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.
As a typical operation of the wireless communication system, the BS 270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC 280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS 270 to transmit forward link signals to the mobile terminal 100.
The mobile communication module 112 of the wireless communication unit 110 in the mobile terminal accesses the mobile communication network based on the necessary data (including the user identification information and the authentication information) of the mobile communication network (such as the mobile communication network of 2G/3G/4G, etc.) built in the mobile terminal, so as to transmit the mobile communication data (including the uplink mobile communication data and the downlink mobile communication data) for the services of web browsing, network multimedia playing, etc. of the mobile terminal user.
The wireless internet module 113 of the wireless communication unit 110 implements a function of a wireless hotspot by operating a related protocol function of the wireless hotspot, the wireless hotspot supports access by a plurality of mobile terminals (any mobile terminal other than the mobile terminal), transmits mobile communication data (including uplink mobile communication data and downlink mobile communication data) for mobile terminal user's services such as web browsing, network multimedia playing, etc. by multiplexing the mobile communication connection between the mobile communication module 112 and the mobile communication network, since the mobile terminal essentially multiplexes the mobile communication connection between the mobile terminal and the communication network for transmitting mobile communication data, the traffic of mobile communication data consumed by the mobile terminal is charged to the communication tariff of the mobile terminal by a charging entity on the side of the communication network, thereby consuming the data traffic of the mobile communication data included in the communication tariff contracted for use by the mobile terminal.
Based on the above hardware structure of the mobile terminal 100 and the communication system, various embodiments of the method of the present invention are proposed.

It should be noted that, as those skilled in the art will appreciate, the gesture of "zooming in" or "zooming out" described in this embodiment may be set arbitrarily according to actual requirements, and may be the same as the gesture of "zooming in" or "zooming out" image scale in the prior art, for example.
Step 302: processing at least part of sub-data in the at least one video data acquired in real time by using at least a first video processing strategy and a second video processing strategy to obtain at least two target sub-video data; the first video processing policy is different from the second video processing policy;

In this embodiment, the different presentation modes may specifically represent different video characteristic parameters of the presented video data; here, the video feature parameter specifically represents the number of video frames in a unit time. That is, the different presentations may specifically characterize the speed of presentation as different, for example, in a slow shot manner, or in a fast shot manner, or in a normal shot manner.
In this way, the data processing method according to the embodiment of the present invention acquires at least one piece of video data in real time in an image acquisition area corresponding to at least one image acquisition device by using at least one image acquisition device, and processes at least part of sub-data in the at least one piece of video data acquired in real time by using at least a first video processing policy and a second video processing policy to obtain at least two pieces of target sub-video data, and further generates the target video data based on the at least two pieces of target sub-video data, so that the video data included in the target video data can be presented in different presentation manners, and therefore, the method according to the embodiment of the present invention enriches user experience and also improves user experience; meanwhile, the requirement of the user on the diversification of the presentation mode is also met.
Example two
Based on the method described in the first embodiment, the embodiment of the invention provides three specific video processing strategies; here, in the process of one-time video acquisition, the following three specific video processing strategies can be used simultaneously, and any two of the three specific video processing strategies can be selected, so that a foundation is laid for enriching the presentation mode. Further, the video processing policy described in this embodiment may be preset, or may be set at any time according to a user operation, for example, a video characteristic parameter input by a user is obtained through a user interaction interface, so as to determine the video processing policy; or, selecting the video characteristic parameters matched with the area size of the display area from a preset relation list (namely a corresponding relation list representing the area size of the display area and the video characteristic parameters) according to the area size of the display area selected by the user, and further determining a video processing strategy; here, as those skilled in the art know, the embodiment of the present invention aims to emphasize that the same video data is processed by different video processing strategies, or different video data is processed, and the target video data is generated by using the processed video data, so that the target video data contains video data that can be presented in different presentation manners, and therefore, the setting process of the video processing strategies described above is only used for explanation, and is not used to limit the present invention.
A first video processing strategy; in particular, the amount of the solvent to be used,
the electronic equipment reduces video characteristic parameters corresponding to at least part of sub data in the at least one piece of video data acquired in real time; the video characteristic parameters represent the number of video frames in unit time; that is to say, the electronic device reduces the number of video frames expected to be displayed in unit time, further delays the display time interval of adjacent video frames, and realizes a processing strategy of slow shots; further, the electronic equipment takes at least part of sub-data in the at least one video data after the video characteristic parameters are reduced as first target sub-video data; wherein the first target sub video data is included in the at least two target sub video data; the first target sub-video data may be presented in a first presentation, for example in a slow-shot presentation.
A second video processing strategy; in particular, the amount of the solvent to be used,
the electronic equipment enlarges video characteristic parameters corresponding to at least part of sub data in the at least one piece of video data acquired in real time; the video characteristic parameters represent the number of video frames in unit time; that is to say, the electronic device increases the number of video frames expected to be displayed in unit time, so as to shorten the display time interval of adjacent video frames and realize the processing strategy of the fast shot; further, the electronic equipment takes at least part of sub-data in the at least one video data with the video characteristic parameters being increased as second target sub-video data; wherein the second target sub video data is included in the at least two target sub video data; the second target sub-video data can be presented in a second presentation, for example in a fast-shot presentation.
In a specific embodiment, because the human eye masks the time domain, that is, the human eye is often unable to perceive details of a fast moving object, the embodiment reduces the data amount of video data by adopting a frame dropping processing mode based on the above features, thereby achieving the purpose of saving storage space. Specifically, the electronic equipment determines a video storage characteristic parameter based on an acquisition characteristic parameter (such as video acquisition duration and the like); the video storage characteristics represent the number of video frames to be stored in unit time; and deleting the video frames in the collected video data according to the determined video storage characteristic parameters, and increasing the video characteristic parameters in the video data collected in real time, so that the aim of reducing the data volume of the target video data is fulfilled. Here, as the video acquisition duration is prolonged, the number of video frames processed by frame dropping is increased; for example, when video acquisition is started, the number of video frames selected from currently acquired video data as target video data in unit time is N; n is a positive integer greater than or equal to 1; and N is less than or equal to the number of video frames in a unit time in the normal video, such as 20 or 30. With the extension of the video acquisition time, for example, when the video acquisition time exceeds a first threshold, assuming ten minutes, the number of video frames selected from currently acquired video data as target video data in unit time becomes M; m is a positive integer greater than or equal to 1 and is less than N; that is to say, when the video acquisition duration exceeds a certain threshold, the number of video frames selected from the currently acquired video data as the target video data in unit time is small, and the purpose of saving the storage space is further achieved. Here, the unselected video frames are discarded video frames.
The third video processing policy may be specifically an existing common video processing policy, and is not described herein again.
Therefore, the embodiment of the invention can process the same or different collected video data by using the three video processing strategies, and further obtain various video data which can be presented in different presentation modes; moreover, the three video processing strategies can be combined in pairs at will, or the three video processing strategies can be simultaneously presented in the video acquisition process, so that the requirement of a user on the diversification of presentation modes is met, the user experience is enriched, and the user experience is also improved.
EXAMPLE III
Based on the method according to the first embodiment or the second embodiment, in this embodiment, after the electronic device generates the target video data, the electronic device stores the target video data; and presenting the at least two target sub-video data in the target video data in different presentation manners in at least a first display area and a second display area of the electronic equipment based on user operation.
Here, in practical applications, the first display area and the second display area may be preset areas or display areas determined according to user operations; further, when the first display area and the second display area are display areas determined according to user operation, the area sizes of the first display area and the second display area may be arbitrarily set according to the user operation.
In an embodiment, the electronic device may further determine a presentation speed of video data presented in the region according to the region size of the display region, that is, the region size of the display region corresponds to the video processing policy; for example, video data presented in a larger display area corresponds to a normal video processing strategy, and video data presented in a smaller display area corresponds to a fast-shot or slow-shot video processing strategy.
Therefore, the perception experience of the user is enriched by presenting the video data in different presentation modes in different presentation areas, and meanwhile, the presentation areas can be areas determined according to user operation, so that the participation sense of the user is improved, the control desire of the user is met, and the user experience is further improved.
It is to be noted that the functions implemented by the methods in the first to third embodiments may be implemented by calling a program code by a processor in an electronic device, and the program code may be stored in a computer storage medium.
