Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Wherein the described embodiments are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Also, in the description of the embodiments of the present application, unless otherwise indicated, "/" means or, for example, A/B may represent A or B; the text "and/or" is merely an association relation describing the associated object, meaning that there may be three relations, e.g., a and/or B, may represent: the three cases where a exists alone, a and B exist together, and B exists alone, and furthermore, in the description of the embodiments of the present application, "plural" means two or more than two.
The terms "first", "second" are used in the following description for descriptive purposes only and are not to be construed as implying or implying a relative importance or implying that the number of technical features is indicated. Thus, a feature defining "a first", "a second", or "a second" may include one or more such feature, either explicitly or implicitly, and in the description of embodiments of the application, the meaning of "a plurality" is two or more, unless otherwise indicated.
The multi-frame synthesizing method, such as a super-resolution algorithm, a multi-frame noise reduction algorithm, a multi-frame night scene algorithm and the like, needs to acquire images of the same shooting object for multiple times, obtains multi-frame images of the shooting object, and then utilizes the multi-frame images to carry out synthesizing processing. The processing flow of the multi-frame synthesis method is generally divided into three stages: and (5) in the frame receiving stage, synthesizing and returning the result. The series of images are combined and processed into a high-quality image by taking multiple images and then utilizing different and similar information in the continuous multi-frame images and combining prior knowledge. The core idea of this approach is to trade time bandwidth for spatial resolution. In order to ensure the continuity of frames before and after the multi-frame algorithm input image, when the multi-frame algorithm is determined to be started for photographing, the camera application prompts a user to photograph in a certain mode. When the multi-frame algorithm needs more input graphs or has larger size, longer waiting time of the user is caused, and negative influence is brought to the user experience.
In view of this, the present application provides a photographing method that is easy and convenient to operate and capable of improving photographing efficiency and user experience. In the method, whether the frame receiving stage is finished can be detected, and when the frame receiving stage is finished, the frame receiving stage is fed back to the camera application to finish the frame receiving of the user mobile equipment. Therefore, the problems of inconvenient photographing operation and poor user experience caused by long waiting time of the user can be avoided.

In order to simplify the photographing operation flow and shorten the waiting time of photographing, the embodiment of the application provides a photographing method. As shown in fig. 3, the flow chart of the method comprises the following steps:
in step 301, image acquisition is performed in response to a photographing instruction.
In the implementation, in order to improve the image quality, the photographing instruction can be responded to prompt that the intelligent terminal is not moved. Thus, the user can take a picture in a correct posture according to the prompt.
Because the multi-frame synthesizing method needs to utilize multi-frame images to improve the shooting quality of the shooting object, the user should keep the posture unchanged when shooting, so as to be convenient for carrying out multiple image acquisition on the shooting object. In order to improve the user experience and shorten the holding time of the photographing posture, in step 302, an image with a specified frame number for a multi-frame synthesis method is acquired, and photographing is prompted to be completed;
after the prompt photographing is completed, the user can move the terminal equipment, so that the waiting time of the user is shortened, and the problem of unchanged operation caused by long-time maintenance of one gesture of the user is solved.
In step 303, the multi-frame synthesis method is used to synthesize the images with the specified frame number, so as to obtain and output a frame of image.
In the embodiment of the application, different threads can be adopted to finish different operation processes, for example, a multi-frame synthesis algorithm is responsible for collecting multi-frame images to execute a multi-frame synthesis method, and a preview thread is responsible for inquiring the state of a frame receiving node and notifying a camera APP after determining that the frame receiving is finished. The camera APP is responsible for interaction with a user and displays the final shooting effect. The overall process flow framework of this embodiment of the application can be summarized as shown in fig. 4 a: the multi-frame synthesis algorithm thread stores the acquired multi-frame image data into the buffer, synchronously judges whether the frame receiving stage is finished, and if the frame receiving stage is finished, the preview thread informs the camera APP, so that the camera APP can prompt a user that photographing is finished, the multi-frame synthesis algorithm thread synthesizes the multi-frame images acquired by the frame receiving node, and outputs the high-quality images to the camera APP for display.
In order to facilitate informing the camera of the end of the APP frame reception, in the embodiment of the present application, a shared data object is set to indicate whether the multi-frame synthesis phase is completed. In the embodiment of the application, the shared data object may have two values, one of which is a first acquisition result and is used for expressing the end of frame receiving, and the other of which is a second acquisition result and is used for indicating that the frame receiving stage has not ended yet.
When the method is implemented, the number of acquired image frames can be counted by a multi-frame synthesis algorithm flow, and if the count reaches the specified number of frames, the shared data object is updated to indicate the first acquisition result (namely, the end of frame receiving is indicated); if the count does not reach the specified number of frames, the shared data object is updated to indicate a second acquisition result (i.e., to indicate that the receiving node is still in progress). Therefore, the state of the frame receiving stage can be maintained conveniently by sharing the data object through the multi-frame synthesis algorithm flow. And meanwhile, the camera APP is convenient to know whether the frame receiving stage is finished.
For example, access to the shared data object may be implemented as a preview thread; and if the shared data object indicates a first acquisition result, determining that the image with the specified frame number is acquired. For example, the multi-frame composition algorithm flow and the preview thread may use parameters of the same shared data object to perform read and write operations on the shared data object. The same shared data object may be provided to both threads for operation.
For example, as shown in fig. 4b, the multi-frame algorithm process acquires the shared data object at the beginning of the first frame process, sets the value thereof to indicate that the frame receiving phase has not ended, updates the shared data object after the frame receiving phase is ended, and configures the value thereof to be the end of the frame receiving phase. Before the frame is received, if the preview flow accesses the shared data object, the preview flow can know that the frame is not received yet according to the value of the preview flow.
The preview flow can periodically poll the shared data object, and after the frame receiving is finished, the preview flow can acquire the frame receiving end based on the shared data object, and can inform the camera APP of the frame receiving end through the system state Metadata, so that the camera APP can prompt a user to shoot to be finished. Thereafter, the multi-frame composition algorithm flow may reset the state of the shared data object to a default value. The default value may be defined as not ending the frame or as not being enabled. The shared data object may be released when exiting the preview flow or the multi-frame algorithm flow. The shared data object is created again waiting for the next photographing.
When in implementation, the multi-frame synthesis algorithm flow and the preview flow share the same parameter of the shared data object, so that the two flows can share the same shared data object. And adding an updating flow of the shared data object in the multi-frame synthesis algorithm flow, for example, counting the acquired frame number, judging whether the frame receiving is finished, and updating the shared data object based on a judging result. In addition, the access release flow of the shared data object is added in the multi-frame algorithm flow so as to release resources in time.
In order to facilitate the preview thread to acquire the status of the frame receiving stage, in the embodiment of the present application, a corresponding mutual exclusion lock may be set for the shared data object. Whether accessing or overwriting a shared data object requires locking the mutex lock to perform an access operation or a overwrite operation.
For example, before the preview thread accesses the shared data object, the mutex lock is locked, and if the lock failure indicates that the thread of the multi-frame composition algorithm is operating on the shared data object, the thread can access the shared data object later to obtain the latest result of the frame receiving stage. If the locking is successful, the shared data object can be accessed to know whether the frame receiving stage is finished. After access, the preview thread releases the mutex lock so that the multi-frame composition algorithm flow can update the shared data object.
Similarly, when the multi-frame synthesis algorithm thread operates the shared data object, the mutual exclusion lock needs to be locked first, if the locking fails, the preview thread is reading the shared data object, and the shared data object can be updated later after the preview thread releases the mutual exclusion lock. After the multi-frame composition algorithm thread updates the shared data object, the mutual exclusion lock is released in time so that the preview thread can access the shared data object.
When the method is implemented, the identification of the shared data object required by the updating operation of the shared data object in the multi-frame synthesis algorithm thread is the same as the identification of the shared data object required by the access operation of the preview thread, so that the operation of the same shared data object is realized.
In other embodiments, to avoid repeated creation of the shared data object, the multi-frame composition algorithm thread and the preview thread may use predefined parameters of the shared data object to create the shared data object with whom the thread operated first. For example, when the preview thread accesses the shared data object first, if the shared data object is not accessed, the shared data object may be created based on predefined parameters first, and then the mutex lock may be released. The multi-frame composition algorithm flow then updates the shared data object with the same predefined parameters.
Conversely, when the multi-frame composition algorithm flow updates the shared data object first, the multi-frame composition algorithm flow creates the shared data object based on the predefined parameters and updates, and then releases the mutex lock. The preview thread may then access the shared data object using the same predefined parameters.
In the embodiment of the application, when the intelligent terminal supports multiple types of multi-frame synthesis methods, each multi-frame synthesis method can independently correspond to one shared data object, namely, different types of multi-frame synthesis methods and shared data objects have a one-to-one correspondence, so that the threads of the multi-frame synthesis methods of the same type and the threads of the previewing threads can be ensured to accurately access the corresponding shared data objects.
Fig. 5 is a schematic flow chart of a photographing method according to an embodiment of the present application, including the following steps:
in step 501, the camera APP presents a camera APP operation interface, such as that shown in fig. 6, including a photographing control.
In step 502, if the user clicks the photographing control to trigger photographing by the multi-frame synthesizing method, the multi-frame synthesizing algorithm thread responds to the photographing instruction to collect the image, and meanwhile, as shown in fig. 6, the camera APP prompts the user not to move the mobile phone.
In step 503, the multi-frame composition algorithm thread counts the acquired images, and locks the mutual exclusion lock of the shared data object when the count is up to a specified number of frames, i.e., the frame receiving phase is completed.
In implementation, the thread of the multi-frame synthesis algorithm can update the shared data object periodically, or update the shared data object after determining that the frame is received.
In step 504, if the multi-frame synthesis algorithm thread locks the mutex successfully, the shared data object is updated to indicate the first acquisition result, and then the mutex is released.
In step 505, the preview thread locks the mutex lock and accesses the shared data object if the lock is successful.
In step 506, if the access to the shared data object indicates the first acquisition result, the preview thread notifies the camera APP to prompt the user that the photographing has ended. At this point the user may move the handset.
In step 507, the multiple synthesis algorithm threads synthesize one frame of image by using a multi-frame synthesis algorithm, and then the synthesized image is presented by the camera APP. The camera APP as shown in fig. 6 shows a synthesized high quality image.
