It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.

The mobile terminal may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a stationary terminal such as a digital TV, a desktop computer, and the like.

The mobile terminal 100 may include a wireless communication unit 110, an a/V (audio/video) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, and a power supply unit 190, etc. Fig. 1 illustrates a mobile terminal having various components, but it is to be understood that not all illustrated components are required to be implemented. More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include at least one of a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits a broadcast signal and/or broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information and transmits it to a terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated information may also be provided via a mobile communication network, and in this caseThe broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive a broadcast signal by using a signal such as multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO)^@) A digital broadcasting system of a terrestrial digital broadcasting integrated service (ISDB-T), etc. receives digital broadcasting. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).

The mobile communication module 112 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless internet module 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The short-range communication module 114 is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth^TMRadio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee^TMAnd so on.

The location information module 115 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module is a GPS (global positioning system). According to the current technology, the GPS module 115 calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS module 115 can calculate speed information by continuously calculating current position information in real time.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal. The microphone 122 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and the like.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. 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, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal 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 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 may provide an output to notify the mobile terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like. In addition to audio or video output, the alarm unit 153 may provide output in different ways to notify the occurrence of an event. 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 (incomingmunication) 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 and 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, and the like) that has been or will 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.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 181 for reproducing (or playing back) multimedia data, and the multimedia module 181 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The setup module 210, the acquisition module 220, the measurement module 230, and the storage module 240 are used for image acquisition.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof. For a hardware implementation, the embodiments described herein may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, an electronic unit designed to perform the functions described herein, and in some cases, such embodiments may be implemented in the controller 180. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

Each BS270 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 BS270 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 BS270 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 sector of a particular BS270 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 Global Positioning System (GPS) satellites 300 are shown. 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 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 BS270 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 MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the above mobile terminal hardware structure and communication system, various embodiments of the present invention are proposed.

As shown in fig. 3, a first embodiment of the present invention proposes a mobile terminal with multiple cameras, including:

a setting module 210, configured to receive an initial focusing area and at least one extended focusing area set by a user in an image capture window; certainly, in a specific implementation process, an initial focusing area and at least one extended focusing area set by default in the mobile terminal may also be adopted;

the acquisition module 220 is configured to acquire an initial image according to the set initial focusing area information, and record depth-of-field information corresponding to the initial focusing area;

the measuring module 230 is configured to measure and record depth-of-field information corresponding to each extended focusing area according to the set information of each extended focusing area;

and the storage module 240 is configured to store the initial image and the recorded depth information in an associated manner.

It should be noted that the multi-camera in the embodiment of the present invention refers to at least two cameras. Shooting an image through one camera, and determining depth information through the other camera; or one camera is used for shooting images, and the depth of field information is determined by combining the two cameras.

Wherein the setting information may be location information.

Each depth of field information includes depth of field information corresponding to the initial focusing area and depth of field information corresponding to each extended focusing area.

The mobile terminal comprises multimedia equipment such as a mobile phone, a PDA, a tablet personal computer, a game machine and the like.

According to the embodiment of the invention, an initial image is acquired according to the set initial focusing area information, the depth of field information corresponding to the initial focusing area is recorded, and the depth of field information corresponding to each extended focusing area is measured and recorded according to the set extended focusing area information; and the initial image and the recorded depth of field information are stored in a correlation mode, so that only one image can be collected and stored for the same shooting picture, but a plurality of images with different depths of field can be displayed, the image storage space can be effectively saved, and the user experience is effectively improved.

The embodiment of the invention is briefly described by taking a mobile phone with a binocular camera as an example.

The dual cameras are generally used in a combined operation to capture an image with depth information to improve the layering of the image.

As image quality improves, image capacity also improves. In the embodiment of the invention, when the binocular camera is used for shooting the image with the depth of field information, the image is locally stored.

When a picture with the depth of field is shot, one camera is used for shooting an image, and the depth of field information is determined by the other camera; or one camera is used for shooting images, and the depth of field information is determined by combining the two cameras.

Therefore, when the image with the depth of field is locally stored, the image is collected according to the original depth of field selection area, the depth of field information corresponding to the image is obtained, and then the associated storage is carried out. That is, only one image is displayed in the gallery.

By the operation, the storage space occupied by the picture storage can be effectively saved.

As shown in fig. 4, includes:

step 1, a user sets an initial focusing area and an extended focusing area in an image acquisition window. Of course, the initial focusing area may be set by default through the mobile phone.

And 2, acquiring an image according to the setting information of the initial focusing area, and recording depth of field information corresponding to the initial focusing area.

And 3, measuring and recording the depth of field information corresponding to each extended focusing area according to the setting information of each extended focusing area.

And 4, storing the acquired image and the recorded depth of field information in a correlation manner. The stored image effect is shown in fig. 4.

And 5, when the user needs to display the image corresponding to the extended depth of field selection area, synthesizing the image required by the user according to the acquired image and the depth of field information corresponding to the extended depth of field selection area. The display effect is shown in fig. 5.

It should be noted that the circles in fig. 4 and 5 are only used to indicate the initial focusing area and the extended focusing area, and in a specific implementation, the circles are not necessarily displayed on the stored picture.

Therefore, the embodiment of the invention only needs to collect one image and record the depth of field information corresponding to each depth of field selection area, and the image required by the user can be synthesized according to each depth of field information and the collected image, thereby effectively reducing the storage space occupied by storing the collected image and improving the user experience.

On the basis of the first embodiment, modified embodiments of the first embodiment are further proposed, and it is to be noted herein that, in order to make the description brief, only the differences from the first embodiment are described in each modified embodiment.

In an embodiment of the present invention, the storage module is specifically configured to encode each recorded depth information;

According to the embodiment of the invention, each depth of field information is coded into the file header information in a coding mode, so that the storage space occupied by storing the collected images is further reduced, and the user experience is improved.

In another embodiment of the present invention, the storage module is further configured to remove depth information of the acquired image to obtain an original image;

According to the embodiment of the invention, the original image is obtained by eliminating the depth of field information of the acquired image; the original image and the recorded depth of field information are stored in a correlation mode, and the depth of field information is removed from the original image, so that the storage space occupied by image storage is further reduced compared with the original image, only one image is collected and stored for the same shooting picture, but a plurality of images with different depths of field can be displayed, the image storage space can be further effectively saved, and the user experience is effectively improved.

In another embodiment of the present invention, the terminal further includes:

Due to the improvement of image quality, the image capacity is also improved, and when the user uses cellular data to share the image, the user may be brought with larger flow consumption. According to the embodiment of the invention, when the multi-camera is used for shooting the image with the depth of field information, the image is locally stored. Because one camera takes an image and the other camera determines the depth of field (or two cameras jointly find the depth of field information) when taking a picture with the depth of field. Therefore, the embodiment of the invention locally stores the image (initial image) with the depth of field, simultaneously reserves the original image and the depth of field information corresponding to the acquired image, and stores the original image and the acquired depth of field information in a correlation manner, namely, only one image is displayed in the gallery; when the user shares the image, the network environment of the terminal at the moment is determined, if the image is in the flow metering environment, the original image and the depth information corresponding to the acquired image are used as sending objects, and if the image is not in the flow metering environment, the image with the depth is used as the sending object. When the receiver receives the original image and the acquired depth-of-field information corresponding to the image, the original image with the depth-of-field is restored through synthesis of the original image and the acquired depth-of-field information, so that data flow consumed by a user for sharing the image is effectively reduced, and user experience is improved.

Further illustrating the embodiments of the invention:

the home terminal mobile terminal encodes the original image carrying the depth of field information to obtain an original image data stream;

and sending the original image data stream to a terminal at the opposite end.

Receiving an original image data stream by an opposite terminal;

then decoding the original image data stream according to a decoding mode appointed by the home terminal mobile terminal to obtain an image to be synthesized;

receiving a focusing area selected by a user on an image to be synthesized, and determining corresponding depth-of-field information according to the focusing area information;

and synthesizing the image to be synthesized and the determined depth of field information to obtain the user required image of the opposite terminal.

Further, receiving a focusing area selected by a user on an image to be synthesized, and determining corresponding depth information according to the focusing area information, may further include:

analyzing file header information of an image to be synthesized;

when the file header information carrying the depth of field information is analyzed, receiving a focusing area selected by a user on an image to be synthesized, and determining corresponding depth of field information according to the focusing area information;

and when the file header information carrying the depth of field information is not analyzed, the image to be synthesized is the user required image of the opposite terminal.

In a further embodiment of the present invention, the terminal further comprises an editing module and/or a display module;

For example, as shown in fig. 4, when editing the initial image, it is detected that the user selects (e.g., long-presses) the initial focusing area, and at this time, the depth information corresponding to the initial focusing area may be used as the first depth information.

As shown in fig. 4 and 5, when it is detected that the user selects the extended focus area when displaying the image, the depth information corresponding to the extended area may be used as the second depth information.

The embodiment of the invention can only collect and store one image aiming at the same shot picture, but can realize the display of a plurality of images with different depths of field and/or realize the editing of a plurality of images with different depths of field, thereby effectively saving the image storage space and effectively improving the user experience.

Based on the above embodiments, the present invention can further process the acquired initial image or the original image.

For example, a large number of photos are generally stored in the mobile terminal, and the photos are generally categorized according to the shooting time, the character attributes, and the like. At present, as the dual cameras gradually become the standard configuration of the mobile phone, the special attribute of the dual cameras provides a new picture processing mode for the pictures shot by the dual cameras.

The above embodiments can obtain the depth of field data of the photographed focusing object, so that after the picture is photographed by using the dual cameras and the depth of field data of the focusing object in the picture is recorded at the same time, the gallery of the mobile terminal can be divided into three or more storage areas, which are respectively a macro mode corresponding to a depth of field of 0-0.5m, a close-range mode corresponding to a depth of field of 0.5-3m, a long-range mode more than 3m, and the like;

acquiring all pictures shot by a mobile terminal, respectively identifying a focusing object or area in each picture, and extracting depth-of-field data corresponding to the corresponding focusing object or area;

and respectively bringing the corresponding depth-of-field pictures into the corresponding storage areas according to the depth of field corresponding to the three storage areas.

Furthermore, the depth of field data of the stored pictures in the corresponding storage areas are analyzed, the picture with the minimum depth of view in the macro mode is used as the first page of the macro mode album, the picture with the minimum depth of view in the near mode is used as the first page of the near mode album, and the picture with the minimum depth of view in the far and near modes is used as the first page of the far mode album.

Furthermore, the distance between the eyes of the user and the screen is detected at certain intervals, and the picture with the corresponding depth of field in the image library is automatically called as the desktop background according to the difference of the distance.

Furthermore, the pressure of pressing the screen is related to the depth of field in the pictures in the gallery, the pressure applied to the screen is detected at intervals of preset time, and the pictures with the depth of field corresponding to the pressure are used as the desktop background.
