Detailed Description

In embodiments of the present application, the following terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

In order to facilitate understanding of the embodiments of the present application, related concepts related to the embodiments of the present application will be briefly described.

The photographing parameters may include a shutter (shutter), an exposure time, an Aperture Value (AV), an Exposure Value (EV), and a sensitivity ISO. The following description will be made separately.

The shutter is a device for controlling the time of light entering the camera to determine the exposure time of an image. The longer the shutter remains in the open state, the more light that enters the camera, and the longer the exposure time corresponding to the image. Conversely, the shorter the shutter remains in the open state, the less light enters the camera and the shorter the corresponding exposure time of the image.

The exposure time refers to the time required for the shutter to open in order to project light onto the photosensitive surface of the photosensitive material of the camera. The exposure time is determined by the sensitivity of the photosensitive material and the illuminance on the photosensitive surface. The longer the exposure time, the more light enters the camera, the shorter the exposure time, and the less light enters the camera. Thus, a long exposure time is required in a dark scene and a short exposure time is required in a backlight scene.

The aperture value is the ratio of the focal length of the lens (lens) in the camera to the lens light-passing diameter. The larger the aperture value, the more light that enters the camera. The smaller the aperture value, the less light enters the camera.

The exposure value is a value indicating the light transmission capability of the lens of the camera by combining the exposure time and the aperture value. The exposure value may be defined as:

Wherein N is an aperture value, t is exposure time, and the unit is seconds.

ISO, for measuring the sensitivity of the backsheet to light, i.e. the sensitivity or gain. For a non-sensitive film, a longer exposure time is required to achieve the same imaging as the brightness of the sensitive film. For sensitive negatives, a shorter exposure time is required to image at the same brightness as the insensitive negative.

Among the photographing parameters, a shutter, an exposure time, an aperture value, an exposure value, and ISO, the electronic device may algorithmically implement at least one of Auto Focus (AF), auto exposure (automatic exposure, AE), and auto white balance (auto white balance, AWB) to implement automatic adjustment of the photographing parameters.

The automatic focusing means that the electronic device obtains the highest image frequency component by adjusting the position of the focusing lens so as to obtain higher image contrast. The focusing is a continuously accumulated process, and the electronic equipment compares the contrast of the images shot by the lens at different positions, so that the position of the lens when the contrast of the images is maximum is obtained, and the focal length of the focusing is further determined.

Automatic exposure refers to the electronic device automatically setting an exposure value according to the available light source conditions. The electronic device can automatically set the shutter speed and the aperture value according to the exposure value of the current acquired image so as to realize the automatic setting of the exposure value.

The color of the object can be changed due to the projected light color, and the images collected by the electronic equipment can have different color temperatures under different light colors. White balance is closely related to ambient light. Regardless of the ambient light, the camera of the electronic device can recognize the white color and restore other colors with the white color as a reference. The automatic white balance can realize that the electronic equipment adjusts the fidelity degree of the image color according to the light source condition. 3A, auto focus, auto exposure and auto white balance.

Illustratively, the exposure value may be any one of-24, -4, -3, -2, -1, 0, 1,2,3, 4, 24.

And the exposure image corresponding to EV0 is used for indicating the exposure image captured by the determined exposure value 0 when the electronic equipment realizes exposure through an algorithm. And the exposure image corresponding to the EV-2 is used for indicating the exposure image captured by the determined exposure value-2 when the electronic equipment realizes exposure through an algorithm. And the exposure image corresponding to EV1 is used for indicating the exposure image captured by the determined exposure value 1 when the electronic equipment realizes exposure through an algorithm. And so on, and will not be described in detail herein.

Wherein, every 1 increase in exposure value will change one-step exposure, i.e. the exposure (which is the integral of the illuminance received by a certain surface element of the object surface in time t) is doubled, for example, the exposure time or the aperture area is doubled. Then an increase in exposure value will correspond to a slower shutter speed and a smaller f-value. As can be seen from this, EV0 increased the exposure value by 2 relative to EV-2, changing the two-stage exposure, and EV1 increased the exposure value by 1 relative to EV0, changing the one-stage exposure.

Here, when the exposure value EV is equal to 0, the exposure value is generally the optimum exposure value under the current illumination condition. Correspondingly, the exposure image correspondingly acquired by the electronic device under the EV0 condition is the best exposure image under the current illumination condition, and the best exposure image can also be called as a reference exposure image.

A memory may also be provided in the processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that the processor 110 has just used or recycled. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Repeated accesses are avoided and the latency of the processor 110 is reduced, thereby improving the efficiency of the system.

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.

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.

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.

S3322, in response to user operation of the auxiliary control in the first shooting parameter setting interface, displaying a second shooting parameter setting interface and changing corresponding shooting parameters.

It should be appreciated that operating with respect to the adjunct control in the different first shooting parameter setting interface, the electronic device may display a different second shooting parameter setting interface. The second shooting parameter setting interface comprises the same accessory control as the corresponding first shooting parameter setting interface, and the second shooting parameter setting interface further comprises a preview image.

It should be understood that the user operation includes a slide operation, an input operation, etc., to which the present application is not limited in any way.

For example, as shown in fig. 9 (a), for an accessory control (control Y52) corresponding to a first sub-shooting parameter control in the shooting parameter setting interface 901, when a sliding operation for the control Y52 is detected, the electronic device may display a shooting parameter setting interface 902 shown in fig. 9 (b), where the sliding operation is a user operation for the accessory control, and the shooting parameter setting interface 902 is a second shooting parameter setting interface.

The shooting parameter setting interface 902 further includes a control Y53, and when the control Y53 is changed in response to another slide operation by the user, the zoom magnification is also changed.

For example, as shown in fig. 10 (a), for an accessory control (control Y62) corresponding to the second sub-shooting parameter control in the shooting parameter setting interface 1001, when a sliding operation of the user on the control Y62 is detected, the electronic device may display a shooting parameter setting interface 1002 as shown in fig. 10 (b), where the sliding operation is a user operation on the accessory control, and the shooting parameter setting interface 1002 is the second shooting parameter setting interface.

The shooting parameter setting interface 1002 includes a control Y62, and the top status bar of the shooting parameter setting interface 1002 may also display the adjusted speed and other shooting parameters. For example, in connection with one of the foregoing examples, the recording duration has been adjusted to 30 minutes (min), the sheeting duration is unlimited, and the adjusted rate is 90x in response to a sliding operation for control Y62. Subsequently, when the sliding operation for the control Y62 is continuously detected, the value corresponding to the velocity in the top status bar is also changed.

For example, as shown in fig. 11 (a), for the accessory control (control Y72) corresponding to the third sub-shooting parameter control in the shooting parameter setting interface 1101, when a sliding operation of the user for the control Y72 is detected, the electronic device may display the shooting parameter setting interface 1102 shown in fig. 11 (b), where the sliding operation is a user operation for the accessory control, and the shooting parameter setting interface 1102 is a second shooting parameter setting interface.

The shooting parameter setting interface 1102 includes a control Y72, and the top status bar of the shooting parameter setting interface 1102 may also display the adjusted film forming duration and other shooting parameters. For example, in combination with the two previous examples, the rate has been adjusted to 90x, the recording duration has been adjusted to 30min, and the adjusted sheeting duration is 3min in response to the sliding operation for control Y72. Subsequently, when the slide operation for the control Y72 is continuously detected, the numerical value corresponding to the piece forming duration in the top status bar is also changed.

It should be explained that, the recording duration indicates the duration of the video recording of the electronic device, and the film forming duration indicates the duration of the generated target video stream.

For example, as shown in fig. 12 (a), for an accessory control (control Y82) corresponding to a fourth sub-shooting parameter control in the shooting parameter setting interface 1201, when a click operation of a user on a specific shooting parameter name or value in the control Y82 is detected, the electronic device may display the shooting parameter setting interface 1202 shown in fig. 12 (b), and based on the shooting parameter setting interface 1202, the user may change the value corresponding to any shooting parameter in the control Y82. The clicking operation and the inputting operation are user operations for the auxiliary control, and the shooting parameter setting interface 1202 is a second shooting parameter setting interface.

Wherein the shooting parameter setting interface 1202 includes a control Y82, and a numerical value corresponding to each shooting parameter included in the control Y82 can be changed based on an input operation. The top status bar of the shooting parameter setting interface 1202 may also display other shooting parameters, and in combination with the above three examples, the rate has been adjusted to 90x, the recording duration has been adjusted to 30min, and the sheeting duration has been adjusted to 3min.

S3323, switching to a preview interface. When the adjustment operation for the shooting parameters is detected, the shooting parameters corresponding to the returned preview interface are the adjusted shooting parameters.

It should be understood that when the user triggers the photographing parameter setting sub-process, but the photographing parameter adjustment is not actually performed, the returned preview interface is the same as the photographing parameter corresponding to the previously displayed preview interface.

For example, as shown in (b) of fig. 9, when the electronic apparatus detects that the sliding operation is stopped or after stopping for a preset period of time, it automatically switches to the preview interface shown in (c) of fig. 5, at which time the photographing parameters corresponding to the preview interface 31 after switching are different from the photographing parameters corresponding to before adjustment.

For example, as shown in (b) in fig. 9, when the electronic device detects that the sliding operation is stopped, the four sub-photographing parameter controls are photographing parameter setting interfaces in an unselected state, and at this time, the photographing parameter setting interface 901 may further include a return control, such as a cross beside the time-lapse photographing, for indicating to return to the interface associated with the previous stage. Thus, when a clicking operation for the return control is detected, the shooting parameter setting interface in which all the four sub-shooting parameter controls are in an unselected state can be returned to the preview interface, such as the preview interface 31, or when a clicking operation for the control X3 in the shooting parameter setting interface in which all the four sub-shooting parameter controls are in an unselected state is detected, the shooting parameter setting interface can be returned to the preview interface.

The above description of the procedure of returning to the first shooting parameter setting interface after the shooting parameter adjustment is illustrated in fig. 9, and the procedure of returning to the first shooting parameter setting interface after the shooting parameter adjustment corresponding to fig. 10 and 11 may refer to the above description and will not be repeated herein.

It should be understood that, through the shooting parameter setting sub-processes described in S3321 to S3323, the shooting parameters related to multiple shooting involved in the delayed shooting scene may be manually adjusted and set, so that the delayed shooting may be performed subsequently based on the user' S requirement, thereby improving the user experience.

The second process S340 includes S341 and S342, and S341 and S342 are described in detail below.

S341, detecting clicking operation for the filter control.

Optionally, the operation of clicking the filter control is illustrated in S341, and S341 may also instruct the electronic device to start the filter setting, for example, by voice or other instruction information, for detecting an instruction to start the filter setting.

S342, in response to a click operation for the filter control, a filter setting sub-flow is triggered (S3421 to S3423).

The filter setting sub-flow indicates a flow of invoking a certain filter effect by the electronic device based on the operation of the user on the filter control in the time-lapse photographing mode.

In the embodiment of the application, the filter setting sub-flow can comprise clicking operation for any icon indicating the filter effect, sliding operation for a plurality of icons indicating different filter effects and the like.

Illustratively, the filter setting sub-process may include S3421 and S3423, and S3421 to S3423 are described in detail below with reference to fig. 13, respectively.

S3421, a first filter setting interface is displayed in response to clicking operation of the filter control in the preview interface.

Optionally, the first filter setting interface includes an accessory control of the filter control, such as a plurality of filter effect options and an option of not increasing the filter effect, which may also be referred to as an original image option. Wherein the plurality of filter effects may include vivid, blue-colored, neutral gray, etc.

Illustratively, the electronic device may display a filter setting interface 24 in response to a click operation on a filter control, as shown in fig. 14 (a), and the filter setting interface 24 is a first filter setting interface, as shown in fig. 14 (b). In response to the clicking operation, the filter control Y4 is in an on state, and meanwhile, an accessory control (control Y9) corresponding to the filter control, such as a plurality of icons indicating different filter effects and icons corresponding to original image options, is also displayed on the filter setting interface 24. When the filter effect is started, the default effect is the original image.

S3422, determining a target filter effect in response to the user operation of the auxiliary control in the first filter setting interface, and displaying a second filter setting interface in combination with the target filter effect.

It should be appreciated that operating with respect to the adjunct control in the first filter setting interface, the electronic device may display a second filter setting interface, where preview images may correspond to different filter effects.

The second filter setting interface includes the same accessory control as the first filter setting interface, but because the target filter effect is set, the preview image included in the second filter setting interface is different from the original preview image in filter effect, but the image content is the same.

It should be understood that the user operation includes a slide operation, a click operation, or the like, to which the present application is not limited in any way.

Illustratively, as shown in (b) of fig. 14, for the filter setting interface 24, the electronic device may detect a sliding operation of the user with respect to the accessory control (control Y9), and when it is determined that the user selects "effect 1" as the target filter effect, the electronic device displays the filter setting interface 25 as shown in (c) of fig. 14. The sliding operation is a user operation for the accessory control, and the filter setting interface 25 is a second filter setting interface. The preview image displayed on the filter setting interface 25 has a target filter effect corresponding to "effect 1" combined, and the display effect is different from that of the preview image displayed on the filter setting interface 24. Here, "effect 1" may be used to indicate "vivid", "effect 2" is used to indicate "blue tone", and "effect 3" is used to indicate "middle gray".

S3423, switching to the preview interface. When the adjustment operation for the filter is detected, the filter effect corresponding to the preview image in the returned preview interface is the target filter effect.

It should be understood that when the user triggers the filter setting sub-flow, but the filter adjustment is not actually performed, the returned preview interface is the same as the previously displayed preview interface in terms of the corresponding effect, and is the original image effect or the same filter effect.

Illustratively, when the electronic apparatus detects that the slide operation is stopped or after stopping for a preset period of time, the electronic apparatus automatically switches to the interface 26 shown in fig. 14 (d), the interface 26 being a preview interface, or as shown in fig. 14 (c), the filter setting interface 25 may switch to the interface 26 in response to a click operation for the filter control Y4, or the filter setting interface 25 may switch to the interface 26 in response to a click operation for an area other than the control Y9 in the filter setting interface 25. At this time, the filter effect corresponding to the interface 26 is different from the filter effect corresponding to the preview interface before adjustment.

For example, in the filter setting interface 25 shown in fig. 14 (c), a return control may be further set to instruct to return to the interface associated with the previous stage, so that after the filter effect is adjusted, the user may return to the preview interface from the filter setting interface 25 by clicking the return control, but the filter effect corresponding to the preview image in the returned preview interface is the target filter effect.

It should be understood that, through the filter setting sub-processes described in S3421 to S3423, manual adjustment can be performed for the filter effect involved in the delayed photographing scene, so that delayed photographing can be performed subsequently based on the user' S requirement, and the user experience is improved.

S350, detecting clicking operation for the shooting control.

Optionally, the operation of clicking the shooting control is illustrated in S350, and the shooting start operation may also be detected in S350, for example, by using voice or other indication information to instruct the electronic device to start shooting.

S360, shooting is performed based on the set shooting parameters and/or the filter in response to the clicking operation, and a target video stream is generated and stored.

Optionally, the first and second processes may be performed after S350, that is, after shooting is started, shooting parameter setting and/or filter setting may be performed. It will be appreciated that in this manner, the shooting parameters and filter effects will only be combined in the part of the video stream acquired after the setup is completed.

S310 to S360 are exemplified by the procedure in which the electronic device detects the user' S shooting parameter adjustment and filter adjustment. Alternatively, as an implementation, the electronic device may also perform only S310 to S330, S350, and S360, that is, the electronic device may detect only the process of the user for photographing parameter adjustment and photographing. As another implementation, the electronic device may also perform only S310, S320, S340, S350, and S360, that is, the electronic device may detect only the process of the user for filter adjustment and photographing.

In the embodiment of the application, after entering the time-lapse shooting mode, a user can set shooting parameters and/or filter lenses by operating related controls on a display interface, so that before shooting, the user can manually adjust specific shooting parameters and filter lenses related to the time-lapse shooting in advance based on own needs, and then, when shooting, the electronic equipment shoots based on the adjusted shooting parameters and/or target filter lens effects, thereby being capable of adaptively shooting time-lapse videos with different effects according to different needs, meeting various needs of the user and improving user experience.

Because the shooting parameters and the filters are changeable, the setting mode is simple, for example, the snapshot rate in video recording can be preset, then the electronic equipment can acquire corresponding delay video based on the rate set by a user in a delay shooting mode, in the process, only the image correspondingly acquired at the rate is required to be processed, compared with the mode of acquiring a large number of images firstly and generating delay video for the frame extracted after image processing in the prior art, the mode provided by the application can reduce a large amount of power consumption, and in addition, because the target video stream is acquired based on the snapshot image processing, the image quality is higher than that of the prior art.

The implementation process related to the above step S360 is described in detail below with reference to fig. 15.

Fig. 15 is a software architecture diagram according to an embodiment of the present application. As shown in fig. 15, the software architecture provided by the embodiment of the present application may include an application layer, an application framework layer, a hardware abstraction layer, and a hardware layer.

By way of example, the application layer may include a series of application packages. As shown in fig. 15, the application package may include a camera application and a gallery application.

The application program layer is positioned at the top end of the whole frame, bears the responsibility of directly carrying out interaction by a user, and once receiving shooting or video recording requirements of the user, sends the requirements to the application program frame layer through an interface until the application program frame layer carries out feedback processing results. For example, as shown in fig. 15, in the embodiment of the present application, the result includes a preview stream and a target video stream, and then the application layer feeds back the result to the user.

The application framework layer is located between the application layer and the hardware abstraction layer, and the application framework layer provides an application programming interface (application programming interface, API) and a programming framework for the application of the application layer. The application framework layer includes a number of predefined functions.

The application framework layer is a framework of applications, and a developer can develop some applications based on the application framework layer under the development principle of following the framework of the applications. In the embodiment of the application, the application framework layer comprises an access interface and the like corresponding to the camera application.

The hardware abstraction layer is used for abstracting hardware and providing a virtual hardware use platform for an operating system.

For example, as shown in FIG. 15, the hardware abstraction layer may include a camera hardware abstraction layer and an image processing module. The functions of each module will be described in detail in the following embodiments, and are not described in detail here.

Illustratively, as shown in fig. 15, the hardware layer mainly includes a display screen and a camera module (e.g., including a video camera 193), and the like.

Next, taking an example of clicking operation on the shooting control after detecting that the user performs shooting parameter setting according to the first procedure shown in fig. 7 and performs filter setting according to the second procedure, the interaction procedure between the modules in the electronic device is described in detail in conjunction with the software architecture diagram shown in fig. 15.

S411, after detecting the set shooting parameters and the set filters, the camera application receives a click operation of the shooting control by the user.

Illustratively, as shown in (d) of fig. 14, the user has manually set the shooting parameters and filters in the time-lapse photography mode, such as a rate of 90X, a recording time of 30min, etc., and the filter is a vivid filter indicated by "effect 1", and after setting, the user has clicked on control X3 to instruct the electronic device to shoot according to the shooting parameters and target filter effects that were just set.

S412, responding to the clicking operation, and generating and sending a video recording request to the hardware abstraction layer by the camera application program.

The step S412 may specifically include, in response to the clicking operation, the camera application generating and sending a video request to the application framework layer, where the application framework layer receives the video request and then sends the video request to the hardware abstraction layer.

It should be noted that, the shooting parameters involved in the video recording request are performed based on the original settings of the camera, and the application does not change this. For example, if the recording rate in the default time-delay shooting mode is 240x, the shooting parameters carried by the issued recording request are 240x.

S413, responding to clicking operation, and generating and sending a snapshot request in video to a hardware abstraction layer by the camera application program.

It should be understood that the photographing request issued by the camera application includes the set photographing parameters and the set filters.

It should be further understood that the delayed shooting mode is equivalent to a video mode in a special case, so that in general, in the prior art, in response to an operation of a user on a shooting control, a video request is issued and is correspondingly taken as a delayed video after the video stream is acquired and processed. For example, assuming that the user sets the rate to 90x, the snapshot request in the video includes a snapshot rate value in the video of 90x.

The recording request and the snapshot request in the recording may be collectively referred to as a shooting request.

S414, the hardware abstract layer transmits the video request and the snapshot request in the video to the hardware layer, and receives two paths of data streams (such as a first data stream and a second data stream) returned by the hardware layer.

The step S414 may specifically include that the hardware abstraction layer issues the video request and the snapshot request in the video to the camera module in the hardware layer through the included camera hardware abstraction layer, and the camera module returns the result to the camera hardware abstraction layer after collecting the image data.

It should be understood that the two data streams respectively correspond to video and photo, and the camera module is equivalent to acquiring image data related to a video request and image data related to a photo request at the same time, or the camera module is equivalent to transmitting a data stream corresponding to video by using a video channel and transmitting a data stream corresponding to photo.

For example, the first data stream sent by the camera module into the camera hardware abstraction layer may be used to generate a video stream, where the video stream is a video obtained by shooting with a default shooting parameter corresponding to the electronic device in the time-lapse shooting mode.

For example, the second data stream sent from the camera module to the camera hardware abstraction layer may be used to generate a photographing stream, where the photographing stream is photographed by using photographing parameters set by the user in the time-lapse photographing mode, and the obtained multi-frame images or photographing streams.

S415, after the hardware abstraction layer generates the initial video stream based on the first data stream, discarding the initial video stream.

Specifically, the camera hardware abstraction layer in the hardware abstraction layer generates an initial video stream based on the first data stream, discards the initial video stream, but does not delete, or may delete.

Illustratively, the initial video stream may include a plurality of frames of initial video images located in the RAW domain.

It should be understood that, since the present application is equivalent to taking a picture by only using a video recording channel, the initial video stream acquired based on the video recording request is not data of the video to be finally acquired, and no processing is required, so that the initial video stream can be discarded after being generated.

S416, after the hardware abstraction layer generates the initial snapshot stream based on the second data stream, the initial snapshot stream is processed.

Optionally, the hardware abstraction layer includes an image processing module in addition to the camera hardware abstraction layer.

Specifically, a camera hardware abstraction layer in the hardware abstraction layer generates an initial snapshot stream based on the second data stream, and transmits the initial snapshot stream to the image processing module for processing.

For example, the initial snapshot stream may include multiple frames of initial snapshot images located in the RAW domain.

It should be understood that the application is equivalent to photographing by using a video channel, and the corresponding photographing parameters are collected based on the photographing parameters set by the user, so that the corresponding photographing flow is collected according to the requirement of the user without any resource waste.

In addition, the photographing mode by using the video channel does not affect the original functions of related chips related to the electronic equipment, and the function of taking a snapshot in video is bound with the video function.

For example, fig. 16 is a schematic structural diagram of each module in a hardware abstraction layer provided by an embodiment of the present application, as shown in (a) of fig. 16, a chip related to the present application may be a high-pass chip of CamX-CHI architecture, which includes a case (Usecase) having a correspondence with a delayed photography mode in a camera application, and Usecase includes Feature2 (Feature 2), where Feature2 includes a corresponding Pipeline (Pipeline). When the camera hardware abstract layer receives a shooting request, the Feature2 can be used for sending a result returned by the hardware layer to a Pipeline for processing so as to acquire a video stream and a shooting stream, and a video recording function and a shooting function in video recording are realized.

Alternatively, S415 and S416 may be performed simultaneously. For example, when the shooting control is clicked, the initial video stream and the initial snapshot stream are acquired in a triggering manner in response to the issued video recording request and the snapshot request in the video recording, and the initial video stream is discarded and the initial snapshot is processed.

Optionally, the image processing module comprises a snap shot image processing module.

Specifically, a snap image processing module in the image processing module processes the initial snap stream after receiving the initial snap stream so as to improve the image quality.

Optionally, the snap image processing module may include a first filtering sub-module, and at least one of an anti-shake processing sub-module and a first format conversion sub-module.

For example, as shown in fig. 16 (b), if the set target filter effect is "vivid", the first filter mirror module may process in combination with the set filter effect during the process of the present application, so that the image included in the processed initial snapshot stream carries the "vivid" filter effect. That is, the first filter sub-module is configured to process an input image in combination with a filter effect set by a user, and generate an image with the filter effect.

If the user does not set the filter effect, the first filter submodule does not need to process the input image, and this step can be skipped.

As shown in fig. 16 (b), the initial snapshot flow may include other data such as gyroscope sensor (gyro) data and image feature points, and based on this, the anti-shake processing sub-module may combine the data to perform anti-shake processing on the initial snapshot image in the initial snapshot flow or the image processed by the first filter sub-module, so as to eliminate the influence of shake on the image in the acquisition process of the camera module, and improve the definition of the image.

The gyroscope sensor data can be acquired based on the gyroscope sensor, the image feature points can be extracted by utilizing a network model provided by a related technology, and the anti-shake algorithm can be an intra-frame anti-shake algorithm provided by the related technology, so that the application is not limited to the intra-frame anti-shake algorithm.

Illustratively, as shown in (b) of fig. 16, the first format conversion submodule is configured to perform format conversion on the initial snapshot stream, the image output by the first filter submodule, or the image output by the anti-shake processing submodule, and convert the image in the RAW domain into the image in the YUV domain, so that the processed initial snapshot stream may include multiple frames of images in the YUV domain.

The amount of image data in the YUV domain is smaller than that in the RAW domain, so that the speed of subsequent transmission can be increased. Of course, the first format conversion sub-module may perform other format conversion, which is not limited in any way by the present application.

Illustratively, the snapshot image processing module may further include a buffering sub-module for buffering data during processing, such as all or part of the images in the processed initial snapshot stream.

It should be understood that, if the rate is set when the shooting parameters are set as described above, the number of frames of images included in the processed initial snapshot stream is the same as the number of frames of images included in the initial snapshot stream, that is, corresponds to the rate in the shooting parameters set by the user. Thus, in the processing process of the application, the snapshot image processing module does not need to carry out frame extraction processing.

It should be understood that fig. 16 is only an example for a snap image processing module, and the snap image processing module may also include other functional sub-modules, which is not limited in any way by the present application.

S417, the hardware abstraction layer returns the processed initial snapshot stream to the gallery application program.

S418, the gallery application program encodes the processed initial snapshot stream, and then generates a target video stream for storage.

The target video stream may also be referred to as a delayed video, that is, a slice obtained in response to a click operation of the shooting control by the user in the delayed shooting mode.

In S411, after the user clicks the shooting control, the shooting control in the display interface may be switched to an end control, before S417, the user may click the end control to end shooting, as a way, in response to a clicking operation for the end control, the camera module stops acquiring the initial video stream and data related to the initial snapshot stream, the hardware abstraction layer returns the processed initial snapshot stream generated from clicking the shooting control to clicking the end control to the gallery application program, and the gallery application program may encode the processed initial snapshot stream by using the first encoding module to generate the target video stream and store the target video stream.

In another way, the hardware abstraction layer can return the processed image in the initial snapshot stream to the gallery application program in real time, the first coding module in the gallery application program codes the image, and the gallery application program stores the generated target video stream when responding to the operation of the ending control.

Optionally, the present application further includes:

S419, the camera application program sends a preview request to the hardware abstraction layer.

It should be understood that when the camera application is turned on, when the camera application is switched from another mode to the time-lapse photographing mode and does not start photographing, and when the time-lapse photographing mode is started, after photographing is started to before photographing is finished in response to a click operation on a photographing control, the camera application needs to issue a preview request in the process.

S420, the hardware abstract layer sends a preview request to the hardware layer and receives a data stream (third data stream) returned by the hardware layer.

The step S420 may specifically include that the hardware abstraction layer issues the preview request to the camera module in the hardware layer through the included camera hardware abstraction layer, and the camera module returns the result to the camera hardware abstraction layer after collecting the image data.

It should be appreciated that the data stream corresponds to the preview image, and the data stream may be acquired based on default preview capture parameters of the electronic device.

S421, after generating an initial preview stream based on the third data stream to the hardware layer, the hardware abstraction layer processes the initial preview stream.

Illustratively, the initial preview stream may include a plurality of frames of initial preview images located in the RAW domain.

Optionally, the hardware abstraction layer includes an image processing module, and the image processing module includes a preview image processing module.

Specifically, the preview image processing module processes the initial preview stream after receiving the initial preview stream to improve the image quality.

Optionally, the preview image processing module may include a second filter mirror module.

For example, as shown in fig. 16 (c), if the filter is set to be "bright" when the filter is set as described above, the second filter mirror module may be used to process the input image in conjunction with the user setting the filter effect to generate an image with the filter effect after the filter is set in the process of the present application.

It should be noted that, if the user does not turn on the filter effect or before setting the filter effect, the preview image processing module does not need to process the input image, and skips this step.

Optionally, the preview image processing module may further include a second format conversion sub-module.

Illustratively, the second format conversion sub-module may be configured to format convert an output image of the initial preview stream or the second filter sub-module into an image in the RAW domain and convert the image into an image in the YUV domain.

The image data volume in the YUV domain is smaller than that in the RAW domain, so that the subsequent transmission rate can be improved. Of course, the second format conversion sub-module may perform other format conversion, which is not limited in any way by the present application.

S422, the hardware abstraction layer returns the processed initial preview stream to the camera application program.

S423, the camera application program codes the processed initial preview stream and generates a preview stream for display.

The camera application program can utilize the second coding module to code the processed initial snapshot stream, and generate a preview stream for display.

Fig. 17 is an example of an initial preview stream, an initial video stream, and an initial snapshot stream provided by an embodiment of the present application. The initial preview stream and the initial video stream may be acquired according to default shooting parameters, and the initial snapshot stream may be acquired according to shooting parameters set by a user, which are different.

In the embodiment of the application, because in a professional video recording channel, photos can be simultaneously captured in the video recording process, in the implementation mode, after the shooting parameters and the filters are set in the time-lapse shooting mode, the initial video stream and the initial captured stream are acquired based on the mode, then the initial video stream is discarded without any processing, so that a large amount of power consumption can be saved.

In addition, the shooting parameters and the filter setting mode are simple, the user uses a lower threshold, the shooting parameters are set by the user to capture, and only the images acquired by the set shooting parameters are required to be processed.

In addition, the image processed by the method is the image captured by the professional video recording channel, the processing mode is the processing of the photographed image, and the steps of anti-shake and the like are combined, so compared with the mode of simply processing the preview image to obtain the delay video in the prior art, the quality of the delay video obtained by the method is higher.

The time-lapse photographing method provided by the embodiment of the present application is described in detail above with reference to fig. 1 to 17, and the device embodiment of the present application will be described in detail below with reference to fig. 18 to 19. It should be understood that the apparatus in the embodiments of the present application may perform the methods of the foregoing embodiments of the present application, that is, specific working procedures of the following various products may refer to corresponding procedures in the foregoing method embodiments.

Fig. 18 is a schematic structural diagram of an electronic device according to an embodiment of the present application. The electronic device 500 includes a display module 510 and a processing module 520.
