       FIG. 7  is a structural diagram of a system for processing photographing and/or camera shooting according to an examplary implementation mode of the present disclosure. As shown in  FIG. 7 , the photographing and/or camera shooting component and the mobile terminal in the structure are separable, namely the photographing and/or camera shooting component therein is a separable photographing and/or camera shooting component. As shown in  FIG. 1 , the system comprises two parts: one part: a mobile terminal A (or named a host A, which is equivalent to an above-mentioned end body), a card slot B in the mobile terminal A and an interface C 1  on the card slot B; and the other part: a separate device D (which is equivalent to the above-mentioned separate device in function), and an interface C 2 , corresponding to the interface C 1 , on the separate device D, wherein the separate device D comprises at least one of: a photographing and/or camera shooting component E, a rechargeable power supply F, a controlling component H and a wireless communication component G. The two parts are described below respectively. 
     The mobile terminal A (which is uniformly referred to as the host A below). The host A provides a screen for a user to watch a picture and effect of the photographing and/or camera shooting component E, provides the screen for the user to operate and preview photographing and/or camera shooting, and supplies power to the photographing and/or camera shooting component E, and communicates with the photographing and/or camera shooting component E. 
     The card slot B (as the above-mentioned card slot): the card slot B in the host A is configured to fix the photographing and/or camera shooting component E, and can be removed manually by a user. 
     Interface C 1  (as the above-mentioned physical interface): a group of Interfaces C 1  in the card slot B at least provide the following functions: power supplying and charging service is provided for the photographing and/or camera shooting component E by using a battery of the host A via the interface C 1 ; and the host A performs data communication and command communication with the photographing and/or camera shooting component E via the interface C 1 , so that the photographing and/or camera shooting component E transmits collected image data to the host A. The interface C 1  can be a USB (Universal Serial Bus) interface, or can be one of other self-defined interfaces. 
     The separate device D: the separate device D comprises at least one of: the photographing and/or camera shooting component E, the rechargeable power supply F, the controlling component H and the wireless communication component G, and a component which is formed by integrating together a group of the above equipment. The separate device D can communicate with the host A via an interface C 2 , can be fixed to the host A via the card slot B without falling, and can be automatically stripped by the user. Meanwhile, the separate device D can be provided a similar adhesion device capable of adhering to glass, and all devices included by the separate device D is described below. 
     The photographing and/or camera shooting component E: the photographing and/or camera shooting component E is a main component on the separate device D, and completes a photographing and/or camera shooting function. 
     The rechargeable power supply F: When the separate device D is separated from the host A, the rechargeable power supply F supplies needed power to the functions of the separate device D. When the separate device D is connected to the host A, the rechargeable power supply F is charged from the host A in case of low electric quantity. 
     The wireless communication component G: the wireless communication component G can be a Wireless Fidelity (wifi) component or can be a Bluetooth component. The wifi component is emphatically discussed here. The wifi component is configured to perform wifi communication with the host, transmit data to the host A and receive a control instruction from the host A. 
     The controlling component H (equivalent to the detecting component  42  and the controlling component  44  in function): the controlling component can be a software component. The user receives an instruction instructing whether to take a photograph from the host A via the wireless communication component G, and transmits data obtained by photographing to the host A via the wireless communication component G. It is important to note that when the separate device D and the host A are connected together, the controlling component H receives the instruction and transmits the data via the interface C; and when the separate device D and the host A are separated, the controlling component H receives the instruction and transmits the data via the wireless communication component G. The controlling component H mainly controls the photographing and/or camera shooting component E. 
     The communication mode of the wireless communication component G: which comprises: the wireless communication component G is connected to the host A in a wifi display mode, the wireless communication component G is connected to the host A in a wifi direct mode, and the wireless communication component G is connected to the host A in a wifi Access Point (AP)-client mode. In the above first mode, the host A only views the data of the photographing and/or camera shooting component E passively without the ability of control. In the other two modes, the host A can control photographing or camera shooting respectively. 
     The processing of photographing and/or camera shooting is described below according to the two conditions that the separate device D and the host A are connected and separated. 
     1. When the separate device D and the host A are connected together, the wireless communication component G does not work, the rechargeable power supply does not supply power, and charging operation of the host A via the interface C (a common term of the interface C 1  on the host and the interface C 2  of the separate device D) is accepted only in case of low electric quantity. When the user performs photographing or camera shooting via the screen of the host A or other keys, a command is transmitted to the controlling component H via the interface C, and the controlling component H controls the photographing and/or camera shooting component E to perform photographing or camera shooting, and transmits original data of an image or a video to the host A via the interface C. 
     2. When the separate device D and the host A are separated and the interface C is no longer connected, the power supply F will automatically turn into a power supply state. When the controlling component H detects that the interface C is no longer connected, the wireless communication component G is started to search for a wifi signal. Meanwhile, when the host A detects that the interface C is no longer connected, the wifi component is automatically started and set as an AP component, and a Service Set Identifier (SSID) of the wifi component is set as camera-ssid. Meanwhile, the wireless communication component G searches for the SSID (camera-ssid), and a password is automatically input for connection after the SSID is found, wherein the set SSID name and password are both set in advance. 
     After wifi is connected, the host A and the controlling component H can directly communicate in a prescribed protocol mode. A communication distance depends on a distance of wifi communication of the host A. The effect of performing photographing and/or camera shooting preview on the host A by the user is the same as that before separation. The user can press a photographing key on the same interface, the command is transmitted to the controlling component H via the wifi, the controlling component H controls the photographing and/or camera shooting component E to take a photograph, and then data are collected and transmitted to the host A via the wifi to form a picture. 
     When the user performs camera shooting on the host A, camera shooting data which is collected in real time are transmitted to the host A via the controlling component H, is displayed on the screen and is stored in a file system. 
     After being separated from the host, the separate device D can be adhered to the glass, a tile or other devices via an adhesion system. 
     After the separate device D is separated from the host A, the wifi is connected and an Internet Protocol (IP) is allocated, the host A sends a control command to the controlling component H; after a bilateral negotiation, the controlling component H will compress preview data of the photographing and/or camera shooting component E constantly and then transmit the compressed preview data to the host A, the host A decompresses the compressed preview data and then sends the decompressed data into a display for the user to preview the data on the screen, and the effect is the same as that before separation. 
     Descriptions are performed below by adopting a micro-USB interface component as the physical interface C and adopting Universal Plug and Play (upnp) for communication therebetween. 
     When the separate device D is separated from the host A, the physical interfaces C of the separate device D and the physical interfaces C of the host A will be separated in a separation process. 
       FIG. 8  is a communication mode diagram of separation of a separate device D from a host A according to an examplary implementation mode of the present disclosure. As shown in  FIG. 8 , after the physical interfaces C are separated, the host A will automatically detect USB disconnection. At this time, the host A will automatically open the wifi component, the wifi component is set from a common client component to the AP component, a fixed password is set, and the SSID is named camera-ssid. 
     After the physical interfaces C are separated, the rechargeable power supply F start power supplying operation to perform system power supplying on the whole separate device D. 
     After the physical interfaces C are separated, when the controlling component H detects USB disconnection, the wireless communication component G is started, that is, the wifi is opened, and the set AP (camera-ssid) starts to be searched; after the camera-ssid is found, connection is performed to go into a host AP according to the fixed password, and the host AP allocates an address as 192.168.0.2; and at this time, the own IP address of the host A is 192.168.0.1. 
     After the host A detects the address 192.168.0.2, a Session Imitation Protocol (SIP) of a control protocol component is started, and the SIP is sent to the controlling component H to negotiate for communication; after the bilateral negotiation succeeds, preview data of a photographing component, collected by the controlling component H, are YUV data firstly; after compressing into H264, the YUV data are transmitted to the host A via a Rapid Transport Protocol (RTP). The host A decodes and recovers the H264 into the YUV data, and the data are sent to the screen to be played. At this time, the user will see separated camera data in real time via the host A. 
     A photographing instruction is initiated by the operation of the host A. The host A converts the photographing instruction into a message command of the SIP, and sends the message command to the controlling component H. After receiving the message command, the controlling component H starts the photographing and/or camera shooting component E to take a photograph, and after photographing succeeds, 2000K is returned to the host via the SIP; and a jpg format file generated by photographing is sent via the (Real-time Transport Protocol, RTP) to the host to be stored. 
     A photographing instruction is initiated by the operation of the host A. The host A converts the photographing instruction into an invite command of the SIP, and sends the invite command to the controlling component H. After receiving the invite command, the controlling component H performs negotiation, then video transmission is performed between the negotiated parties via the RTP, and a video stream is stored inside a file at a host end. 
     When the separation operation is stopped, the separate device D can be put into the card slot B of the host A. When both the host A and the controlling component H detect USB connection, the wifi component is stopped and closed at the same time. 
     The separation operation is stopped, the charging operation is switched from the rechargeable power supply F to a charging component of the host A and the rechargeable power supply F stops supplying power to the separate device D, and a USB interface supplies power to the separate device D. 
     The separation operation is stopped, and the SIP and the RTP in the controlling component H stop working. A conventional USB mode is switched, and the host A controls the photographing operation and the camera shooting operation.
