The connection relationships between the modules shown in fig. 1 are merely illustrative, and do not constitute a limitation on the connection relationships between the modules of the electronic device 100. Alternatively, the modules of the electronic device 100 may also use a combination of the various connection manners in the foregoing embodiments.

The wireless communication function of the electronic device 100 may be implemented by the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor, the baseband processor, and the like.

The antennas 1 and 2 are used for transmitting and receiving electromagnetic wave signals. Each antenna in the electronic device 100 may be used to cover a single or multiple communication bands. Different antennas may also be multiplexed to improve the utilization of the antennas. For example: the antenna 1 may be multiplexed into a diversity antenna of a wireless local area network. In other embodiments, the antenna may be used in conjunction with a tuning switch.

The electronic device 100 may implement display functions through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, and is connected to the display 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

Illustratively, the display screen 194 may be used to display images or video.

Alternatively, the display screen 194 may be used to display images or video. The display 194 includes a display panel. The display panel may employ a liquid crystal display (liquid crystal display, LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Mini light-emitting diode (Mini LED), a Micro light-emitting diode (Micro LED), a Micro OLED (Micro OLED), or a quantum dot LED (quantum dot light emitting diodes, QLED). In some embodiments, the electronic device 100 may include 1 or N display screens 194, N being a positive integer greater than 1.

Illustratively, the electronic device 100 may implement a photographing function through an ISP, a camera 193, a video codec, a GPU, a display screen 194, an application processor, and the like.

Illustratively, the ISP is used to process data fed back by the camera 193. For example, when photographing, the shutter is opened, light is transmitted to the camera photosensitive element through the camera, the optical signal is converted into an electric signal, and the camera photosensitive element transmits the electric signal to the ISP for processing and is converted into an image visible to naked eyes. The ISP can carry out algorithm optimization on noise, brightness and color of the image, and can optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in the camera 193.

Illustratively, a camera 193 (which may also be referred to as a lens) is used to capture still images or video. The shooting function can be realized by triggering and starting through an application program instruction, such as shooting and acquiring an image of any scene. The camera may include imaging lenses, filters, image sensors, and the like. Light rays emitted or reflected by the object enter the imaging lens, pass through the optical filter and finally are converged on the image sensor. The imaging lens is mainly used for converging and imaging light emitted or reflected by all objects (also called a scene to be shot and a target scene, and also called a scene image expected to be shot by a user) in a shooting view angle; the optical filter is mainly used for filtering out redundant light waves (such as light waves except visible light, such as infrared light) in the light; the image sensor may be a charge coupled device (charge coupled device, CCD) or a Complementary Metal Oxide Semiconductor (CMOS) phototransistor. The image sensor is mainly used for photoelectrically converting a received optical signal into an electrical signal, and then transmitting the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV, or the like format.

Illustratively, the digital signal processor is configured to process digital signals, and may process other digital signals in addition to digital image signals. For example, when the electronic device 100 selects a frequency bin, the digital signal processor is used to fourier transform the frequency bin energy, or the like.

Illustratively, video codecs are used to compress or decompress digital video. The electronic device 100 may support one or more video codecs. In this way, the electronic device 100 may play or record video in a variety of encoding formats, such as: dynamic picture experts group (moving picture experts group, MPEG) 1, MPEG2, MPEG3, and MPEG4.

Illustratively, the gyroscopic sensor 180B may be used to determine a motion pose of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., x-axis, y-axis, and z-axis) may be determined by gyro sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects the shake angle of the electronic device 100, calculates the distance to be compensated by the lens module according to the angle, and makes the lens counteract the shake of the electronic device 100 through the reverse motion, so as to realize anti-shake. The gyro sensor 180B can also be used for scenes such as navigation and motion sensing games.

For example, the acceleration sensor 180E may detect the magnitude of acceleration of the electronic device 100 in various directions (typically, x-axis, y-axis, and z-axis). The magnitude and direction of gravity may be detected when the electronic device 100 is stationary. The acceleration sensor 180E may also be used to recognize the gesture of the electronic device 100 as an input parameter for applications such as landscape switching and pedometer.

Illustratively, a distance sensor 180F is used to measure distance. The electronic device 100 may measure the distance by infrared or laser. In some embodiments, for example, in a shooting scene, the electronic device 100 may range using the distance sensor 180F to achieve fast focus.

Illustratively, ambient light sensor 180L is used to sense ambient light level. The electronic device 100 may adaptively adjust the brightness of the display 194 based on the perceived ambient light level. The ambient light sensor 180L may also be used to automatically adjust white balance when taking a photograph. Ambient light sensor 180L may also cooperate with proximity light sensor 180G to detect whether electronic device 100 is in a pocket to prevent false touches.

Illustratively, the fingerprint sensor 180H is used to capture a fingerprint. The electronic device 100 may utilize the collected fingerprint feature to perform functions such as unlocking, accessing an application lock, taking a photograph, and receiving an incoming call.

Illustratively, the touch sensor 180K, also referred to as a touch device. The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a touch screen. The touch sensor 180K is for detecting a touch operation acting thereon or thereabout. The touch sensor 180K may communicate the detected touch operation to the application processor to determine the touch event type. Visual output related to touch operations may be provided through the display 194. In other embodiments, the touch sensor 180K may also be disposed on the surface of the electronic device 100 and at a different location than the display 194.

Currently, the time required for starting the camera is long; for example, in a scene of switching on and off the camera, the user can obviously perceive the waiting process when the camera is started, so that the photographing experience of the user is poor.

Scene one: in the process of starting the camera, the time consumption is long; the user can obviously perceive that a short black screen phenomenon appears.

Illustratively, as shown in fig. 2, the graphical user interface (graphical user interface, GUI) shown in fig. 2 (a) is the desktop 210 of the electronic device; the electronic device detects a click operation on the control 220 of the camera application on the desktop, as shown in fig. 2 (b); after the electronic device detects a click operation on the control 220 of the camera application on the desktop, a black screen may appear during the process of opening the camera application, as shown in (c) of fig. 2; the photo preview interface 230 is displayed after the black screen, as shown in fig. 2 (d).

Scene II: in the process that the camera application program is switched from the preview mode to the photographing mode, the waiting time is long; for example, in preview mode, the electronic device detects that the user clicks the shutter key, which is time consuming between clicking the shutter key and displaying the thumbnail of the captured image; the user usually regards displaying a thumbnail image of the photographed image as completing one photographing, resulting in a long waiting time for the user.

Illustratively, as shown in fig. 3, the display interface 240 shown in (a) in fig. 3 is a display interface of a preview mode of a camera application program, and the display interface 240 includes a photographing control 241; the electronic device detects a click operation on the photographing control 241, as shown in (b) in fig. 3; when the electronic device detects a click operation on the photographing control 241, the camera application program switches from the preview mode to the photographing mode; the electronic device detects a pop-up operation of the photographing control 241, as shown in (c) of fig. 3; detecting a flick operation of the photographing control 241 at the electronic device and running the photographing mode to generate a thumbnail image of the photographed image, displaying a display interface 250, as shown in (d) of fig. 3; currently, a user can obviously perceive that the waiting time between the (c) display interface shown in fig. 3 and the (d) display interface 250 shown in fig. 3 is long, resulting in poor photographing experience of the user.

Scene III: when the camera is invoked by a third party application (e.g., a payment application to scan codes, or a third party camera application), it takes longer time; the user can obviously perceive that a short black screen phenomenon appears.

At present, all link libraries are loaded in the existing shooting method; loading all inherent link libraries of the chips and all customized link libraries, so that the time required by starting the camera application program is long; the starting time of the camera application program waiting for the user is longer, so that the user experience is poor.

The flow of the conventional photographing method is described below with reference to fig. 4.

Fig. 4 is a flow chart of a conventional photographing method. The method 300 as shown in fig. 4 includes S310 to S350; s310 to S350 are described below, respectively.

S310, detecting an operation on the camera application.

Optionally, an operation is detected indicating that the camera application is turned on.

Illustratively, a click operation on the camera application is detected, as shown in (b) of fig. 2.

Optionally, a click operation is detected on a control of the camera functionality in the third party application.

Illustratively, when the electronic device is running an instant messaging application, a click operation of a control of the camera function is detected; or when the electronic equipment runs the payment application program, detecting clicking operation of a control of the camera function; alternatively, a click operation on the third party camera application is detected.

It should be appreciated that the above is illustrated with a click operation; in the embodiment of the application, the clicking operation can also be an operation of starting the camera application program through voice indication; or, indicating an operation of starting the camera application program through other instructions; the present application is not limited in any way.

S320, the camera application program sends a data stream.

S330, sending the data stream to the hardware abstraction layer through the application framework layer.

S340, data flow configuration processing.

It should be appreciated that the data stream configuration process may refer to initializing the operating environment of the electronic device.

The implementation of the data stream configuration process in S340 may include S341 to S343.

S341, loading all the link libraries.

Alternatively, all the link libraries may include link libraries inherent to the load chip and link libraries customized by the load; the link library of the chip platform can refer to a link library inherent to the chip; the inherent link library of the chip is a link library which is necessarily loaded when the chip is operated, and the link library cannot be not loaded under the control of a user; the customized link library may refer to a self-developed (or preconfigured) link library for different electronic devices.

It should be understood that the link library refers to a binary file generated by compiling and packaging an open source library file.

For example, the chip-inherent link library may include, but is not limited to, the following:

a frame synchronization library file (achorsync. So), a demux library file (demux. So), a fusion library file (fusion. So), a universal library file (generc. So), a multi-frame super-resolution library file (mfsr. So), a copy library file (memcpy. So), a serializer library file (seriizer. So), and the like.

For example, the customized link library may include, but is not limited to, the following files:

a high dynamic range algorithm library file (rawhdr. So), a super night scene algorithm library file (rawsuperright. So), and the like.

It should be appreciated that the customized link library may refer to a non-link library in the electronic device; it is understood that it is not a link library inherent in the chip.

S342, selecting a characteristic topological graph.

Wherein, the characteristic topological graph can be understood as the execution logic sequence of the loaded link library; for example, 4 different characteristic topologies are shown in fig. 7 (a), fig. 7 (b), fig. 7 (c), and fig. 7 (d).

It should be noted that, the selection characteristic topological graph may be understood as execution logic for selecting the link library loaded in S341.

S343, cutting the characteristic topological graph.

The cropping process may refer to a process of determining a topology map from a plurality of characteristic topology images.

For example, the characteristic topology map may be cropped based on a request initiation instruction in the electronic device.

It should be understood that a feature may refer to implementing some function of a camera application; the topology map that can be selected based on one characteristic may include a plurality of topology maps; the characteristic topological graph is cut, namely a final adopted topological graph is determined from a plurality of topological graphs; for example, executing S342 based on a certain characteristic results in 4 different topology structures as shown in fig. 7; execution S343 may further determine a topology map that is ultimately employed by a certain characteristic from the selected characteristic topology maps; obtaining a schematic diagram shown in fig. 8 based on a link library required by loading and a topological graph adopted finally; as shown in FIG. 8, any one of F-1, F-2, F-3, F-4, or F-5 in FIG. 8 represents a characteristic; a feature may be understood as a certain function of the camera application; the realization of the characteristics needs to rely on a link library corresponding to the characteristics; by loading the link library, the camera application program can realize a certain function, and the running environment of the electronic equipment is initialized.

S350, instantiation processing.
