Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It is also to be understood that the terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
In order to explain the technical means of the present application, the following description will be given by way of specific examples.
At present, when a terminal performs continuous shooting operation, in the process of performing picture generation processing on image data acquired by a camera to obtain a continuous shooting picture, when an image needing preview processing or other shooting flows needing to be executed exist, the process of performing picture generation processing on the image data acquired by the camera is interrupted, the preview processing of the image or other shooting flows needing to be executed is preferentially completed, and then the process of performing picture generation processing on the image data acquired by the camera is continued, so that the time for acquiring the continuous shooting picture is increased, and the continuous shooting speed is reduced.
For example, as shown in fig. 1, assuming that it takes 100ms of processing time to perform one picture generation process and 30ms of processing time to perform one preview process, assuming that the terminal starts the first picture generation process at 0ms (shown by a solid line in the figure), and at 30ms, there is one image to be previewed, it is necessary to interrupt the first picture generation process, preferentially perform the preview process (shown by a dotted line in the figure), and continue the first picture generation process at 60ms (completion of the preview process), and at 80ms, there are two images to be previewed, and similarly, the terminal interrupts the first picture generation process, preferentially performs the preview process, and continues the first picture generation process at 140ms (completion of the two preview processes), and does not complete the first picture generation process until 190ms, since the second picture generation processing is performed, the first picture generation processing takes 60ms more time, and the time required for acquiring a plurality of pictures increases each time the picture generation processing is interrupted, which reduces the continuous shooting speed.
Based on this, the embodiments of the present application provide a continuous shooting method, apparatus, terminal and computer-readable storage medium, which can be applied to various image processing application scenarios.
Fig. 2 shows a schematic flow chart of an implementation of a continuous shooting method provided in an embodiment of the present application, where the method is applied to a terminal, and can be executed by a continuous shooting device configured on the terminal, and is suitable for a situation where a continuous shooting speed needs to be increased. The terminal can be an intelligent terminal which can realize a photographing function and is used for mobile phones, computers, wearable equipment and the like. The continuous shooting method may include steps 201 to 203.
In the embodiment of the present application, continuous shooting refers to a shooting mode for continuously shooting a plurality of pictures. For example, 5, 10 or other more or less pictures may be taken.
In some embodiments of the present application, the obtaining of the continuous shooting start instruction may include: the method comprises the steps of obtaining a continuous shooting starting instruction triggered by pressing a touch key, and/or obtaining a continuous shooting starting instruction triggered by clicking a preview interface, and/or obtaining a continuous shooting starting instruction triggered according to a detected preset touch gesture, and/or obtaining a continuous shooting starting instruction triggered by voice.
The pressing of the touch key may include pressing a movable key suspended on the preview interface, or pressing a fixed key fixed on the preview interface; or, the pressing touch key is a hidden key which is hidden in a menu bar on the preview interface.
The continuous shooting starting instruction triggered by the click preview interface can comprise a continuous shooting starting instruction triggered by a single click or a continuous shooting starting instruction triggered by continuous multiple click preview interfaces, or a continuous shooting starting instruction triggered by a long-time press preview interface.
The preset touch gesture may include a user-defined touch screen gesture, for example, a touch screen gesture of sliding in various directions (sliding left, sliding right, etc.), a touch screen gesture of drawing a polygon (drawing a circle, drawing a triangle), and the like.
The voice may include a user-defined voice, and for example, the user may trigger a continuous shooting operation by inputting "continuous shooting", "start continuous shooting", "continuous shooting", and the like.
It should be noted that the above triggering mode has the characteristics of diversification, intuition and simplicity, and a user can easily and conveniently trigger the continuous shooting starting instruction through the above triggering mode, so that the operating efficiency of the user in continuous shooting is improved.
After the continuous shooting starting instruction is obtained, the terminal can send a repeated shooting instruction to the camera according to the continuous shooting starting instruction, so that the camera can acquire multi-frame images according to the continuous shooting starting instruction, and the acquired multi-frame images are subjected to image generation processing at the highest processing priority to obtain continuous shooting images.
The processing of generating a picture for a plurality of acquired images with the highest processing priority to obtain a continuous shooting picture may refer to that, in the process of generating a picture for a certain frame of image acquired by a camera, if a new frame of image needs to be previewed or other shooting flows need to be processed, the generation of the picture is preferentially completed, and then the preview processing is performed on the new frame of image or other shooting flows are executed, so that the generation of the picture is not interrupted when the image is generated.
Specifically, if the photographing application of the terminal adopts a CameraII architecture in the google framework, the repeated photographing instruction may be a photographing instruction sent by calling a repeated photographing function setrepeat burst () provided by the framework.
It should be noted that, at present, setretastating burst () function is generally used for video shooting, and is not used for shooting one picture or shooting (continuous shooting) of multiple pictures. The traditional shooting of one picture or multiple pictures adopts a snapshot function captureBurst () provided by a CameraII framework. When a captureBurst () function is used for shooting (continuously shooting) a plurality of pictures, a continuous shooting request with a preset continuous shooting quantity needs to be packaged in the captureBurst () function, only a plurality of pictures corresponding to the preset continuous shooting quantity can be shot at most at one time, and when the captureBurst () function is used for continuously shooting, in the process of generating pictures for image data collected by a camera to obtain continuously shot pictures, when images needing preview processing or other shooting flows needing to be executed exist, the process of generating pictures for the image data collected by the camera is interrupted, the preview processing of the images or other shooting flows needing to be executed is preferentially completed, and then the process of generating pictures for the image data collected by the camera is continued. Therefore, when the captureBurst () function provided by the frame is used for continuous shooting, the continuous shooting frequency is at the upper limit value, and continuous shooting pictures as many as possible can not be taken in a short time, so that the shooting frame rate of the continuous shooting pictures is reduced.
In the setreprintingburst () function adopted by the application, continuous shooting requests with preset continuous shooting quantity do not need to be packaged inside, so that no upper limit value exists for the continuous shooting times, and a user can determine the continuous shooting times according to needs in practical application.
Further, the repeated shooting instruction can instruct the camera of the terminal to perform picture generation processing on the collected multi-frame images at the highest processing priority, and then perform preview processing on a new frame of image collected by the camera or execute processing of other shooting processes, so that the shooting frame rate of the continuous shooting pictures can be guaranteed to the maximum extent, the shooting speed of the continuous shooting pictures is improved, and the technical problems that the continuous shooting speed is low when the terminal performs continuous shooting operation and multiple continuous shooting images cannot be obtained quickly are solved.
For example, as shown in fig. 3, it is assumed that it takes 100ms of processing time to perform picture generation processing and 30ms of processing time to perform preview processing, and it is assumed that the terminal starts the first picture generation processing at 0ms, and during the first picture generation processing, there are two images that need to be previewed, but the terminal still preferentially performs the first picture generation processing, so at 100ms, the terminal has already completed the first picture generation processing, and at this time, it performs the preview processing again, and then starts the second picture generation processing again, and therefore, time to perform the preview processing in each picture generation processing is saved.
As shown in fig. 4a, the continuous shooting method provided by the present application is tested for continuously shooting 20 pictures, and the total time consumed is 14.079-13.154-925 ms.
In the conventional continuous shooting method, when a terminal performs picture generation processing on a certain collected frame of image, if preview processing or other shooting processes to be executed are required to be performed on a new frame of image collected by a camera at the moment, the preview processing or other shooting processes to be executed are firstly completed, and then the picture generation processing is continuously completed.
As shown in fig. 4b, the current continuous shooting method is tested for continuously shooting 20 pictures, and the total time is 59.488-58.085-1403 ms.
From the experimental data, the speed of continuously shooting 20 pictures by using the continuous shooting method provided by the application can be improved by 34.07%.
In some other embodiments of the present application, in order to further increase the continuous shooting speed, the continuous shooting picture obtained by performing the picture generation processing on the acquired multiple frames of images with the highest priority according to the repeated shooting instruction may further include: and only carrying out picture generation processing on the frame image acquired by the camera, and not carrying out preview processing until the continuous shooting operation is finished, namely, the preview image stays in the preview image when the continuous shooting is started, and is not refreshed, so that the continuous shooting speed is further improved.
It should be noted that, in practical applications, the picture generation process may include: the terminal collects a certain frame of image through a camera, and performs 3A image processing of Automatic White Balance (AWB), Automatic Focusing (AF) and Automatic Exposure (AE) on the image; or, performing AI image processing such as face recognition and scene recognition on the image; or, after the image is subjected to image processing such as beauty processing, blurring processing, anti-shake processing, etc., the processed image is sent to a Jpeg encoder to be encoded, and the Jpeg encoder encodes the image to generate a picture in a Jpeg format, or sent to an encoder in another format to generate a picture in a corresponding format.
And 203, receiving a continuous shooting ending instruction, and finishing continuous shooting operation according to the received continuous shooting ending instruction.
In the embodiment of the application, the repeated shooting instruction is sent to the camera according to the obtained continuous shooting starting instruction, and the continuous shooting picture obtained by carrying out picture generation processing on the collected multi-frame image by the camera according to the repeated shooting instruction is obtained, so that the terminal can ensure the shooting frame rate of the continuous shooting picture to the maximum extent, and the shooting speed of the continuous shooting picture is improved. For example, in the process of performing picture generation processing on a certain frame of image acquired by a camera, if a new frame of image needs to be previewed or other photographing flows need to be processed at this time, the picture generation processing is preferentially completed, and then the new frame of image is previewed or other photographing flows are executed, so that the image is not interrupted when the picture generation processing is performed on the image, the time required by newly inserting the new frame of image acquired by the camera to be previewed or executing the other photographing flows is saved, the continuous shooting picture acquisition efficiency is improved, and the technical problems that the continuous shooting speed is slow and multiple continuous shooting images cannot be quickly obtained when a terminal performs continuous shooting operation are solved.
In practical application, when a moving object needs to be shot or a human expression needs to be shot, a user often uses a video recording function of a terminal to record a video and captures an interested picture in the recording process.
At present, a terminal can only shoot one picture at a time in a video recording process, and due to the fact that the object moves at a high speed, a snapshot opportunity is easily missed, the shot picture possibly does not meet the requirements of a user, and the success rate of snapshot is reduced.
Since the above repeated shooting instruction, for example, setRepeatingBurst () function, may be applied to both video recording operation and continuous shooting operation, that is, a video image and a continuous shooting picture may be generated by using the same metadata while recording a video, in some embodiments of the present application, the obtaining of the continuous shooting start instruction may further include obtaining a continuous shooting start instruction triggered in the video recording process.
For example, as shown in fig. 5, when the user views the preview image 51, a video recording instruction is triggered to record a video, when the user views the preview image 52, the video is kept continuously recorded, a continuous shooting start instruction is triggered to start continuous shooting, when continuous shooting of 10 pictures is completed, a continuous shooting end instruction is triggered to start continuous shooting, and when the user previews the preview image 53, a video recording end instruction is triggered to complete video recording.
In the embodiment of the application, the continuous shooting starting instruction triggered in the video recording process is acquired, and continuous shooting operation is completed according to the continuous shooting starting instruction, so that the terminal can realize continuous shooting in the video recording process, and the success rate of the continuous shooting is improved.
When carrying out the continuous shooting operation, in order to reach better interactive effect, in some embodiments of this application, according to continuous shooting start instruction, send repeated shooting instruction to the camera to the in-process of obtaining the continuous shooting picture that the camera was shot and is obtained can also include: and outputting continuous shooting information.
The continuous shooting information comprises one or more of continuous shooting reminding information, continuous shooting times and continuous shooting sound effect.
For example, as shown in fig. 6, when the CameraII framework is used for continuous shooting, the Hardware Abstraction Layer (HAL) notifies the application layer of completing frame image acquisition through the notification function oneimageavailable () function, and then the application layer may start to perform picture generation processing on the acquired image, at this time, the application layer may further call a continuous shooting frequency display function showburstcapturenber (), and display the continuous shooting frequency in a shooting interface or a video recording interface, or the application layer may call a continuous shooting sound effect play function playCaptureSound () function to play a continuous shooting sound effect during continuous shooting, so as to achieve an effect of prompting a user of continuous shooting information.
In practical applications, a user may need to fast obtain a continuous shooting picture in some shooting scenes, for example, when shooting an object with a fast motion speed, and some shooting scenes still need to perform continuous shooting at a slow speed, for example, when shooting an object with a slow motion speed, and therefore, in some embodiments of the present application, when the continuous shooting start instruction is a continuous shooting start instruction triggered by pressing a touch key, in order to implement adjustment of two continuous shooting speeds, after obtaining the continuous shooting start instruction triggered by pressing the touch key, the method may further include: and acquiring the pressure value of the pressed touch key.
The step of pressing the pressure value of the touch key may include acquiring the pressure value of pressing the touch key through a force sensor of the terminal.
Correspondingly, the above-mentioned sending is shot the instruction repeatedly to the camera according to the start instruction of taking a continuous photograph to obtain the continuous photograph picture that the camera was shot and is obtained, can include: and if the pressure value is larger than the pressure threshold value, sending a repeated shooting instruction to the camera according to the continuous shooting starting instruction, and acquiring a continuous shooting picture shot by the camera.
In some embodiments of the present application, if the pressure value is less than or equal to the pressure threshold, a continuous shooting instruction is sent to the camera according to the continuous shooting start instruction, for example, the continuous shooting instruction sent to the camera by calling a continuous shooting function captureBurst () is called, and a continuous shooting picture obtained by performing picture generation processing on a captured multi-frame image by the camera according to the continuous shooting instruction is obtained.
It should be noted that, after the pressure value obtained by pressing the touch key is obtained, if the pressure value is greater than the pressure threshold value, it indicates that the user needs to perform fast shooting, at this time, the continuous shooting method provided by the present application may be adopted, that is, a repeated shooting instruction is sent to the camera according to the continuous shooting start instruction, and a continuous shooting picture obtained by performing picture generation processing on the acquired multi-frame image with the highest priority by the camera according to the repeated shooting instruction is obtained; if the pressure value is smaller than or equal to the pressure threshold value, the user is indicated to carry out slow shooting, at the moment, a traditional continuous shooting method can be adopted, namely, a continuous shooting instruction is sent to the camera according to the continuous shooting starting instruction, and continuous shooting pictures obtained by carrying out picture generation processing on collected multi-frame images according to the continuous shooting instruction by the camera are obtained.
It should be noted that other methods for achieving continuous shooting speed adjustment are also applicable to the present application, for example, different continuous shooting start instructions are triggered by using different preset touch gestures to perform continuous shooting speed adjustment, or different continuous shooting start instructions are triggered by using different voice instructions to perform continuous shooting speed adjustment, which is not limited in this application.
In practical applications, for a plurality of similar pictures in a continuously shot picture, a user often only needs to keep one of the pictures and delete the rest of the pictures to reduce occupation of a memory of a terminal, in some embodiments of the present application, in order to improve deletion efficiency of the pictures, as shown in fig. 7, the sending a repeat shooting instruction to a camera according to a continuous shooting start instruction and acquiring the continuously shot picture shot by the camera may include: step 701 to step 703.
In the embodiment of the present application, after a plurality of continuously shot pictures are obtained by the continuous shooting method shown in fig. 2 to 6, a group of continuously shot pictures can be formed by calculating the similarity between every two continuously shot pictures, and when the similarity between the two continuously shot pictures is greater than or equal to the similarity threshold value; and when the similarity between the two continuous shooting pictures is smaller than a similarity threshold value, dividing the two continuous shooting pictures into different groups of continuous shooting pictures, and finally obtaining a plurality of groups of continuous shooting pictures.
For example, in 10 continuous-shot pictures shown in fig. 5, the similarity between five continuous-shot pictures, namely the continuous-shot pictures 54 to 55, is greater than or equal to the similarity threshold, and at this time, the five continuous-shot pictures can be divided into the same group of continuous-shot pictures; similarly, the similarity between five continuous-shot pictures 56 to 57 is greater than or equal to the similarity threshold, and at this time, the five continuous-shot pictures can be divided into the same group of continuous-shot pictures; the similarity between any one of the continuously shot pictures 54 to 55 and any one of the continuously shot pictures 56 to 57 is smaller than the similarity threshold, and therefore, any one of the continuously shot pictures 54 to 55 and any one of the continuously shot pictures 56 to 57 are continuous shot pictures of different groups.
Specifically, the similarity between the continuously shot pictures may be calculated by a structural similarity measurement method, a cosine similarity calculation method, an image similarity calculation method based on a histogram, and the like, which is not limited in the present application.
And step 702, reserving any one continuous shooting picture in each group of continuous shooting pictures, and marking the continuous shooting pictures which are not reserved as images to be deleted.
In some embodiments of the present application, after an unreserved continuously-shot picture is marked as an image to be deleted, a cancellation marking instruction of the image to be deleted may be received, and the image to be deleted corresponding to the cancellation marking instruction is reserved; and/or receiving a marking instruction for the reserved continuous shooting pictures, and marking the reserved continuous shooting pictures corresponding to the marking instruction as images to be deleted.
That is to say, if a user is unsatisfied with the continuous-shot pictures reserved in a group of continuous-shot pictures, the reserved continuous-shot pictures can be marked as images to be deleted, one or more images to be deleted meeting the user requirements are selected from the images to be deleted, and the marks of the images to be deleted are cancelled.
The embodiment of the application obtains the multiunit continuous shooting picture that obtains by many continuous shooting pictures that the similarity is greater than or equal to the similarity threshold value through calculating the similarity between the continuous shooting picture, then keeps arbitrary one continuous shooting picture in every group continuous shooting picture to with the continuous shooting picture mark that does not keep wait to delete the image, receive at last right wait to delete the affirmation instruction of image, according to affirmation deletion instruction deletes waiting to delete the image for when carrying out the deletion of continuous shooting picture, can select the photo that needs to delete in batches automatically, and realize deleting in batches, improved the deletion efficiency of continuous shooting picture, reduced the occupation to terminal storage space simultaneously.
