Description
Technical Field
The embodiment of the invention relates to the technical field of photographing, in particular to a continuous shooting method and electronic equipment.
Background
The continuous shooting function of the camera application (i.e. the image capture application) needs to take a large number of photos quickly, and the main flow is as follows: step 1: the user presses the shooting button for a long time to trigger the continuous shooting function; step 2: the camera application program continuously issues photographing and previewing requests to the system; and step 3: the system receives a photographing + previewing request issued by a camera application program; and 4, step 4: the system processes the photographing request: the system receives an original Image (namely, a RAW Image) output by a Sensor (Sensor), YUV (Y represents brightness, namely, a gray-scale value, and U and V represent chroma) format Image data is obtained after Image Signal Processing (ISP), and finally the YUV format Image data is converted into JPEG (Joint Photographic Experts group) format Image data; and 5: the system processes the preview request: the system receives an original image output by the sensor, and YUV format image data is obtained after image signal processing. Wherein, the steps 4 and 5 are generally executed in parallel, that is, the system processes the photographing request and the preview request simultaneously.
Different electronic devices have hardware differences and, correspondingly, performance differences. For some electronic devices with poor hardware performance, the continuous shooting function may cause the preview frame rate to decrease, i.e. cause the preview to have a pause phenomenon. The reason is that due to hardware performance limitations, it is not possible to handle a large number of shots at the same time and maintain a normal preview. For example, the system needs to occupy ISP hardware when processing a photographing request, and needs to use this hardware for processing a preview request, and for an electronic device with relatively poor ISP hardware performance, if a large number of photographing requests need to be processed in a short time, the preview request cannot be processed, and a pause phenomenon occurs in the preview during a continuous photographing process.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a continuous shooting method according to an embodiment of the present invention, where the method is applied to an electronic device, and includes:
step 101: acquiring a first request, wherein the first request comprises a first preview request and a first photographing request;
specifically, the first image processing module of the underlying system may obtain the preview request + the photographing request from the first image capturing application (i.e., the camera application) on the upper layer.
Step 102: processing the first preview request;
that is, the image data in YUV format is captured by the first image processing module of the underlying system and then returned to the first image capturing application (i.e., the camera application).
Step 103: processing the first photographing request under the condition that the time interval between the first photographing request and the second photographing request is greater than a first duration;
step 104: under the condition that the time interval between the first photographing request and the second photographing request is less than the first duration, discarding the first photographing request;
the first duration is the minimum time interval between the photo requests which can be processed under the condition that each preview request can be processed, and the second photo request is a processed photo request which is earlier in processing time than the first photo request and has the shortest time interval with the processing time of the first photo request.
That is, in the embodiment of the present invention, it is determined to process or not process the first photographing request in the first request, according to the minimum time interval T. Specifically, the minimum time interval T is a minimum time interval between photographing requests that can be processed by the electronic device under the condition that it is ensured that each preview request can be processed normally. That is, if processing of one photographing request is currently started, it takes at least the interval T duration until processing of another photographing request is started, otherwise processing of the preview request is affected. Therefore, if the time interval between the current photographing request and the last photographing request which is determined to be processed is less than T, the photographing request is not processed, so that the preview is ensured not to be jammed normally.
In the embodiment of the invention, the minimum time interval is calculated according to the actual hardware performance of the electronic equipment. For example, suppose the electronic device has only one ISP hardware, and the time for processing one frame of preview image is 20ms (milliseconds), and the time for processing one frame of photographed image is 30 ms. For the preview screen to appear continuous, the frame rate of the preview is typically 30 frames per second, so the time interval between two adjacent frames of preview images is 33.3ms, here for convenience of illustration, it can be considered that the time interval between two adjacent frames of preview images is 30ms, that is, the time interval between two adjacent preview requests can be 30 ms. Therefore, 10ms of idle time remains for each processed frame of preview image, that is, each processed preview request, so that each processed 3 preview requests can be processed simultaneously to finish a photo request, that is, if all preview requests can be processed normally so that the preview is not stuck normally, at least 90ms is left between the photo requests that can be processed by the ISP hardware, and the 90ms is the minimum time interval. Therefore, if the time interval between the first photographing request and the second photographing request is less than the minimum time interval, determining not to process the first photographing request; if the time interval between the first photographing request and the second photographing request is greater than or equal to the minimum time interval, determining to process the first photographing request; wherein, the second photographing request is the photographing request of the last determined processing.
The execution sequence between step 102 and step 103 or step 104 is not limited, and step 102 may be executed simultaneously with step 103 or step 104.
In the embodiment of the present invention, the preview request refers to a request for an image processing module (in the embodiment of the present invention, the first image processing module) of the system to output YUV format image data for a user to preview, and a picture viewed by the user when the user opens the camera is a preview picture. The photographing request is to request an image processing module (in the embodiment of the present invention, the first image processing module) of the system to output JPEG format image data to be saved in the album.
The first request is issued to a first image processing module of the underlying system by a first image acquisition application program.
In the embodiment of the invention, the image processing module (the first image processing module) of the bottom layer system dynamically controls the continuous shooting speed according to the hardware performance of the electronic equipment to ensure that the preview is normal and not blocked, the continuous shooting speed cannot be influenced for the electronic equipment with good performance, and the preview can be ensured for the electronic equipment with poor performance by reducing the continuous shooting speed.
In addition, for the upper image capturing application program (first image capturing application program), the hardware implementation of the bottom layer does not need to be considered in the continuous shooting process, and only the preview request and the photographing request need to be continuously issued to the image processing module (first image processing module) of the system, then the image processing module (first image processing module) of the system calculates the minimum time interval of the photographing request which can be processed while the processing of the preview request is guaranteed according to the hardware performance, and finally in the process of processing the photographing request, the image processing module (first image processing module) of the system dynamically skips the photographing request of which the time interval with the last photographing request which is determined to be processed is smaller than the minimum time interval. That is, if the hardware performance is not sufficient to process the current request for taking a picture while maintaining the preview normal, the current request for taking a picture is skipped.
The continuous shooting method described above is exemplified below.
Taking the above-mentioned electronic device with only one ISP hardware, the time for processing a frame of preview image is 20ms (millisecond), the time for processing a frame of photographed image is 30ms as an example, if the time interval for the first image capture application to issue the request including the photographing request and the preview request is 30ms, then the minimum time interval T is equal to 90 ms. Request issuing and processing sequence diagram referring to fig. 2, of the nine requests, only the photographing request among the requests numbered 1, 4, and 7 is processed, and the photographing request among the other requests is not processed.
Optionally, the electronic device includes a first image capturing application program and a first image processing module; the step of acquiring the first request, the step of processing the first preview request, the step of processing the first photographing request and the step of discarding the first photographing request are all executed by the first image processing module;
in a case that a time interval between the first photographing request and the second photographing request is less than the first duration, discarding the first photographing request includes:
the first image processing module controls to discard the first photographing request;
the first image processing module sends a first notification message to the first image acquisition application program, wherein the first notification message is used for indicating that the first photographing request is discarded.
For example, an ERROR is set to be returned to the first image capturing application to notify the first image capturing application that the photographing request is not processed.
In the embodiment of the present invention, when the image processing module (the first image processing module) of the underlying system determines that the hardware performance of the electronic device cannot process all the photographing requests while ensuring that each preview request can be processed normally, part of the photographing requests are discarded, and after the photographing requests are discarded, the image acquisition application program (the first image acquisition application program) on the upper layer is notified of which photographing requests are discarded, so that the image acquisition application program (the first image acquisition application program) on the upper layer can know which photographing requests do not obtain the corresponding photos.
Optionally, the first request is a request acquired in a continuous shooting state.
In the embodiment of the invention, only when the continuous shooting state is detected, the first shooting request is determined to be processed or not processed according to the minimum time interval. This is because, if the continuous shooting state is not established, the time interval between adjacent shooting requests is long, and the preview is not generally affected by the processing of the shooting request, and therefore, if the continuous shooting state is not established currently, the shooting request is processed by default. Thus, the computational burden on the system can be reduced. In addition, if the user manually inputs a plurality of photographing requests in succession instead of the continuous shooting state, it may be considered that the user wishes to preferentially secure the processing of the photographing request rather than the processing of the preview request.
For example, if the mode of triggering the continuous shooting mode is to press (continuously press) the shooting button for a long time, it may be detected whether the shooting button is pressed for a long time, and if so, it indicates that the shooting button is currently in the continuous shooting state, otherwise, it indicates that the shooting button is not currently in the continuous shooting state.
In addition, the first image processing module of the underlying system may calculate the minimum time interval only when detecting that the image is currently in the continuous shooting state, otherwise, the minimum time interval may not be calculated, so as to reduce the calculation load of the system.
Optionally, the first request is generated according to a first input of a user, where the first input is used to trigger the electronic device to continuously capture at least two images.
For example, the first input may be an input of a long press of a photograph button. During the period that the user presses the photographing button for a long time, the first image acquisition application program continuously issues the photographing request, and meanwhile, in order to maintain the preview continuously, the preview request also needs to be carried in the photographing request, that is, the same request includes both the preview request and the photographing request.
In the embodiment of the present invention, the preview request and the photo request may be issued simultaneously or separately, that is, the first image processing module of the system may receive the preview request and the photo request simultaneously or may receive the preview request and the photo request respectively.
Referring to fig. 3, fig. 3 is a schematic flow chart of a continuous shooting method according to a second embodiment of the present invention, applied to an electronic device, including:
step 201: receiving a second request, the second request comprising a preview request;
the second request is generated by a second image acquisition application program and is issued to a second image processing module, whether the second request comprises the photographing request is determined according to whether the second image processing module of the system finishes processing the photographing request issued last time, if the second image processing module of the system finishes processing the photographing request issued last time, the photographing request is carried in the second request, otherwise, the photographing request is not carried in the second request.
Step 202: processing the preview request;
that is, the second image processing module captures the image data in the YUV format and returns the image data to the second image capturing application (i.e., the camera application).
Step 203: processing the photographing request in a case where the second request includes a photographing request;
wherein, when the third photographing request is processed, the second request comprises the photographing request; the third photographing request is a photographing request with the receiving time earlier than that of the second request.
If the photographing request is not included in the second request, only the preview request in the second request needs to be processed.
The execution sequence between step 202 and step 203 is not limited, and step 202 and step 203 may be executed simultaneously.
In the embodiment of the present invention, the preview request refers to a request for an image processing module (in the embodiment of the present invention, the second image processing module) of the system to output YUV format image data for a user to preview, and a picture viewed by the user when the user opens the camera is a preview picture. The photographing request is to request an image processing module (in the embodiment of the present invention, the second image processing module) of the system to output JPEG format image data to be saved in the album.
In the embodiment of the invention, by increasing the coupling mode of the image acquisition application program (second image acquisition application program) and the image processing module (second image processing module) of the system, in the continuous shooting process, the image acquisition application program (second image acquisition application program) does not issue the request including the preview request and the shooting request by default, but determines whether to issue a new shooting request according to the fact that the image processing module (second image processing module) of the system has the shooting request issued last time or not. The image processing module (second image processing module) of the system also does not need to calculate the minimum time interval between the photo requests which can be processed by the ISP hardware when all preview requests can be processed normally according to the hardware performance so that the preview can be processed normally without jamming.
In the embodiment of the invention, in the continuous shooting process, the image acquisition application program (second image acquisition application program) defaults to carry the preview request in the second request, and determines whether the shooting request is carried in the second request according to whether the last shooting request is processed by the image processing module (second image processing module) of the system, so that the influence of excessive shooting requests on the response of the preview request when the hardware performance of the electronic equipment is insufficient is avoided, and the preview is ensured to be normal without blockage. In addition, compared with the first embodiment, the processing flow of the image processing module (the second image processing module) of the system may be simplified, that is, the image processing module (the second image processing module) of the system does not need to calculate the minimum time interval, and does not need to drop frames (that is, the photographing request is set as ERROR and returned to the second image capturing application program), and only needs to judge whether a photographing request is processed, and if not, the image capturing application program (the second image capturing application program) is notified to issue the photographing request.
The continuous shooting method described above is exemplified below.
Referring to fig. 4, a flow of one embodiment of the present invention includes:
step 301: if the current continuous shooting mode is detected, the second image acquisition application program (which may be referred to as application, the same below) determines whether the sent second request carries the shooting request according to the notification of the second image processing module (which may be referred to as system, the same below) of the underlying system. And if the second image processing module of the bottom layer system informs the second image acquisition application that the photographing request is not processed currently and a new photographing request can be issued, turning to the step 302, otherwise, turning to the step 303.
Step 302: the second image capture application issues a second request comprising a photograph request and a preview request.
Step 303: the second image capture application issues a second request that includes only the preview request.
Step 304: and a second image processing module of the bottom layer system acquires a second request issued by a second image acquisition application program.
Step 305: and a second image processing module of the bottom layer system processes a preview request of the second request, namely, the image data in the YUV format is grabbed and then returned to the second image acquisition application program.
Step 306: and the second image processing module of the bottom layer system processes the photographing request in the second request, and if the photographing request does not exist in the second request, the step is not executed.
Step 307: the second image processing module of the underlying system determines whether the photographing request is processed, and if so, goes to step 308.
Step 308: the second image processing module of the underlying system notifies the second image capturing application that no photographing request is currently being processed, and may issue a new photographing request, for example, may notify the second image capturing application by sending a callback.
For example, if the electronic device has only one ISP hardware, the time for processing one frame of preview image by the ISP hardware is 20ms (millisecond), and the time for processing one frame of photographed image by the ISP hardware is 30ms, the time interval for issuing the request by the second image capturing application program is 30 ms. The issue sequence and the processing sequence of the requests are shown in fig. 5, and only the requests numbered 1, 4 and 7 carry the photographing request, and the other requests do not carry the photographing request.
Optionally, the first request is generated according to a first input of a user, where the first input is used to trigger the electronic device to continuously capture at least two images. For example, the first input may be an input of a long press of a photograph button.
In the embodiment of the invention, in order to maintain the preview continuously, the second image acquisition application program continuously issues the preview request during the period that the finger of the user presses the photographing button for a long time. However, in order to ensure that the preview is not normally jammed, the photographing request is not necessarily carried in each second request carrying the preview request, but is carried only after the previous photographing request has been processed.
Optionally, the electronic device includes a second image capturing application and a second image processing module; wherein the step of receiving a second request, the step of processing the preview request, and the step of processing the photograph request are all performed by the second image processing module;
before the receiving the second request, the method further includes:
and the second image acquisition application program generates a second request comprising a photographing request and sends the second request to the second image processing module under the condition that the second image processing module has processed the third photographing request.
In the embodiment of the present invention, the second request is generated by the second image acquisition application and is issued to the second image processing module of the underlying system, and in order to prevent the excessive photographing requests from affecting the processing of the preview request, the second image acquisition application issues a new photographing request only after the second image processing module has processed the previous photographing request.
Optionally, the method further includes: and sending second notification information to a second image acquisition application program every time a photographing request is processed, wherein the second notification information is used for indicating that no photographing request is currently processed.
That is, each time the second image processing module of the system processes one photographing request, the second image acquisition application program is notified that a new photographing request can be issued. Therefore, during continuous shooting, the second image acquisition application program can generate a second request comprising a shooting request according to the notification of the second image processing module and send the second request to the second image processing module of the system. If the notification of the second image processing module is not received, the photographing request is not issued, so that the preview is not influenced by photographing.
