[0018] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0020] The following is combined with Figures 1 to 6 , the shooting method, shooting device, electronic device and readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0021] In some embodiments of the present application, a shooting method is provided, which is applied to an electronic device, wherein the electronic device includes a first camera module and a second camera module. Figure 1 FIG. 1 is a flow chart of a shooting method provided by some embodiments of the present application. Figure 1 As shown, the shooting method includes:

[0022] Step 102, obtaining first exposure data during zooming of the electronic device;

[0023] The first exposure data is exposure data determined according to image data collected by at least one of the first camera module and the second camera module;

[0024] In an embodiment of the present application, the electronic device includes a first camera module, and the first camera module and the second camera module are used to collect image data of different focal lengths. During the zooming process of the electronic device, the electronic device shoots through at least one of the first camera module and the second camera module, and determines the first exposure data through the image data obtained by the shooting.

[0025] Step 104, performing convergence processing on the first exposure data using the exposure algorithm parameters of the first exposure module to obtain second exposure data;

[0026] It should be noted that the electronic device stores automatic exposure algorithms corresponding to the first camera module and the second camera module respectively, and sets corresponding exposure algorithm parameters.

[0027] In the embodiment of the present application, the first exposure data is converged by the exposure algorithm parameters of the first camera module, so that no matter whether the first exposure data is generated based on the image data collected by the first camera module or the image data collected by the second camera module, the first exposure data is converged by the exposure algorithm parameters of the first camera module, so that the converged second exposure data obtained is the second exposure data after convergence processing based on the exposure algorithm parameters of the first camera module, so that the second exposure data matches the first camera module, thereby improving the smoothness of brightness convergence.

[0028] Step 106, calculating a first exposure parameter and a second exposure parameter according to the second exposure data;

[0029] Exemplarily, the first exposure parameter and the second exposure parameter both include exposure gain and exposure time, which are outputs of an automatic exposure (AE) algorithm.

[0030] Step 108, controlling the first camera module to perform exposure according to the first exposure parameter, and controlling the second camera module to perform exposure according to the second exposure parameter.

[0031] In the embodiment of the present application, the second exposure data is the exposure data after the convergence processing, the first exposure parameter is the exposure parameter that needs to be configured in the first camera module, that is, the first camera module is exposed by the first exposure parameter, and the second exposure parameter is the exposure parameter that needs to be configured in the second camera module, that is, the second camera module is exposed by the second exposure parameter. Since the first exposure parameter and the second exposure parameter are both generated according to the second exposure data, and the second exposure data is the exposure data obtained by converging only through the exposure algorithm parameters corresponding to the first camera module, in the process of controlling the first camera module to expose according to the first exposure parameter and controlling the second camera module to expose according to the second exposure parameter, the consistency of the brightness of the preview image collected by the first camera module through the first exposure parameter and the preview image collected by the second camera module through the second exposure parameter is improved, and when the user adjusts the shooting focal length, the brightness switching process of the preview image in the display screen is smoother.

[0032] In the embodiment of the present application, when the user zooms through the electronic device, the electronic device can obtain the first exposure data determined by the image data collected by at least one of the first camera module and the second camera module, and converge the first exposure data to obtain the second exposure data through the exposure algorithm parameters corresponding to the first camera module corresponding to the first camera module, thereby improving the smoothness of brightness convergence. Then, the first exposure parameters and the second exposure parameters corresponding to the first camera module and the second camera module are generated according to the second exposure data, further improving the consistency of the brightness of the preview image collected by the first camera module and the preview image collected by the second camera module, making the brightness change of the zoom process smoother, reducing the degree of brightness change of the preview image when the user adjusts the shooting focal length, and solving the problem of sudden brightness change of the preview image during the zoom process.

[0033] In some embodiments of the present application, the exposure data includes image statistical data and metadata, and obtaining the first exposure data includes: obtaining the first exposure data according to the first image data collected by the first camera module.

[0034] In the embodiment of the present application, the exposure data includes image statistics (stats) and metadata (Metadata). In the process of determining the first exposure data by the first image data, it is necessary to obtain the image statistics and metadata of the first image data, and determine the first exposure data by the image statistics and metadata.

[0035] Exemplarily, after the first image data is acquired, image statistical data and metadata in the first image data are acquired, and the acquired image statistical data and metadata are determined as the first exposure data.

[0036] In an embodiment of the present application, when the electronic device is in a zooming process, the processor obtains first image data captured by the first camera module, and obtains image statistics and metadata in the first image data as first exposure data.

[0037] It should be noted that, since only the image statistics and metadata in the first image data are used as the first exposure data, there is no need to turn on the second camera module. Exemplarily, when it is detected that the electronic device is in the zoom process, the second camera module is controlled to stop running to reduce the power consumption of the electronic device when shooting.

[0038] In the embodiment of the present application, by using the image statistics and metadata of the first image data captured by the first camera module as the first exposure data, there is no need to obtain the image data captured by the second camera module, and there is no need to perform corresponding processing on the image data captured by the second camera module, thereby further reducing the power consumption required during the shooting process of the electronic device.

[0039] In some embodiments of the present application, the exposure data includes image statistical data and metadata, and obtaining the first exposure data includes: determining the third exposure data based on the first image data captured by the first camera module; determining the fourth exposure data based on the second image data captured by the second camera module; and performing linear addition fusion on the third exposure data and the fourth exposure data to obtain the first exposure data.

[0040] In the embodiment of the present application, the exposure data includes image statistical data and metadata, then the image statistical data and metadata in the first image data are obtained to obtain the third exposure data corresponding to the first camera module, and the image statistical data and metadata of the second image data are obtained to obtain the fourth exposure data corresponding to the second camera module. The third exposure data and the fourth exposure data are then linearly added and fused to obtain the first exposure data.

[0041] In an embodiment of the present application, the first exposure data is exposure data obtained by linearly adding and fusion processing the third exposure data corresponding to the first image data and the fourth exposure data corresponding to the second image data, so that the metering data corresponding to the first camera module and the second camera module can be fused and transitioned, thereby improving the adaptability of the first exposure data to the first camera module and the second camera module and improving the stability of the metering.

[0042] In an embodiment of the present application, when the user controls the electronic device to zoom, first image data captured by the first camera module and second image data captured by the second camera module are obtained, and the third exposure data of the first image data and the fourth exposure data of the second image data are linearly added and fused to generate first exposure data.

[0043] Exemplarily, the first exposure data is calculated by the following relation (1):

[0044]

[0045] Wherein, Y is the first exposure data, n is the number of camera modules, n=2, W i is the weight of the exposure data corresponding to the i-th camera module, X i It is the exposure data output by the i-th camera module.

[0046] Exemplarily, in the case of a total of two camera modules including a first camera module and a second camera module, the third exposure data corresponding to the first camera module and the fourth exposure data corresponding to the second camera module are linearly added and fused according to the above-mentioned relationship (1) to obtain the first exposure data.

[0047] It should be noted that the weight is associated with the shooting focal length. For example, the first camera module and the second camera module correspond to different focal lengths. When the zoom is in the focal length of the first camera module, the weight of the exposure data of the first camera module is increased. When the zoom is in the focal length of the second camera module, the weight of the exposure data of the second camera module is increased.

[0048] In an embodiment of the present application, the first exposure data is obtained by linearly adding and fusing the third exposure data of the first image data and the fourth exposure data of the second image data, thereby further improving the stability of the metering process, and the subsequent convergence processing of the first exposure data is only performed in the first automatic exposure algorithm corresponding to the first camera module, which can improve the brightness convergence stability of the camera module switching process.

[0049] In some embodiments of the present application, the shooting method further includes:

[0050] Obtaining a first effect tuning parameter corresponding to the first camera module, and obtaining a second effect tuning parameter corresponding to the second camera module;

[0051] The exposure algorithm of the first camera module is configured through the first effect tuning parameter and the second effect tuning parameter to update the exposure algorithm parameters of the first camera module.

[0052] In the embodiment of the present application, the first camera module corresponds to a first effect tuning parameter, and the second camera module corresponds to a second effect tuning parameter. Exemplarily, the effect tuning parameter is a Tuning parameter.

[0053] In an embodiment of the present application, after obtaining the first effect tuning parameters and the second effect tuning parameters, the above two effect tuning parameters are configured into the exposure algorithm of the first camera module, thereby updating the exposure algorithm parameters corresponding to the first camera module, so that the subsequent convergence processing of the first exposure data through the exposure algorithm parameters of the first camera module is more accurate, and the converged second exposure data is further matched with the first camera module, thereby improving the smoothness of brightness convergence.

[0054] In some embodiments of the present application, the electronic device includes a first chip and a second chip; and the shooting method further includes:

[0055] When the first chip receives the third image data, the image statistics data and metadata of the third image data are calculated, where the third image data includes at least one of the image data collected by the first camera module and the image data collected by the second camera module; the first chip transmits the image statistics data and metadata of the third image data to the second chip; and the second chip is used to perform exposure convergence processing on the image statistics data and metadata of the third image data.

[0056] In the embodiment of the present application, the third image data is the image data acquired by the first chip at the first camera module and / or the second camera module, and the third image data may be at least one of the image data acquired by the first camera module and the image data acquired by the second camera module. For example, the third image data may be the image data acquired by the first camera module, or the image data acquired by the first camera module and the image data acquired by the second camera module.

[0057] The electronic device includes a first chip and a second chip, wherein the first chip is used to acquire third image data. The first chip transmits the acquired third image data to the second chip for processing, and the second chip can determine first exposure data according to the third image data, and perform subsequent steps of determining first exposure parameters and second exposure parameters according to the first exposure data.

[0058] Exemplarily, the first chip is an application processor (AP) in the electronic device, and the second chip is a system on chip (SOC) chip in the electronic device.

[0059] Figure 2 One of the structural block diagrams of the first chip and the second chip provided in some embodiments of the present application is shown, such as Figure 2As shown, AP is the first chip, SOC is the second chip, the first camera module is 1×sensor, and the second camera module is 2×sensor. AP performs image signal processing (ISP) on the 1×sensor raw image collected by the first camera module and the 2×sensor raw image collected by the second camera module to obtain the first image data and the second image data. The first image data includes 1×stats and 1×Metadata, and the second image data includes 2×stats and 2×Metadata. The AP transmits the first image data and the second image data to the SOC, and the SOC sends the first image data and the second image data corresponding to the 1× focal length and the 2× focal length to the automatic exposure algorithm for processing. The algorithm performs linear addition fusion and synchronization on the first image data and the second image data according to the brightness difference between 1× and 2× and the respective Tuning (effect tuning) parameters. The convergence part is only processed in the 1X automatic exposure algorithm. After the converged second exposure data is processed, the first exposure parameter corresponding to the first camera module and the second exposure parameter corresponding to the second camera module are generated respectively. The exposure parameters include exposure gain and exposure time. Among them, 1×Metering and 2×Metering are the metering processing processes in the automatic exposure algorithm, which are used to obtain the corresponding exposure data, 1×Convergence and 2×Convergence are the convergence processing processes in the automatic exposure algorithm, which are used to perform convergence processing on the exposure data, and 1×Arbitration and 2×Arbitration are the decision processing processes in the automatic exposure algorithm, which are used to generate exposure parameters according to the exposure data after convergence processing. The first image data of the first camera module and the second image data of the second camera module are obtained, and the exposure data corresponding to the first image data and the second image data are converged only in the automatic exposure algorithm corresponding to the first camera module, thereby improving the smoothness of brightness convergence, and generating the first exposure parameter and the second exposure parameter corresponding to the first camera module and the second camera module accordingly, further improving the consistency of the brightness of the preview image collected by the first camera module and the preview image collected by the second camera module, making the brightness change of the zoom process smoother, reducing the degree of brightness change of the preview screen when the user adjusts the shooting focal length, and solving the problem of sudden brightness change of the preview screen during the zoom process. The first chip is used to obtain image data, and does not perform related automatic exposure algorithm processing. The automatic exposure algorithm is only run in the second chip to generate the first exposure parameter and the second exposure parameter, which shares the power consumption of the first chip end and maintains the overall operation stability of the electronic device.

[0060] Figure 3 The second structural block diagram of the first chip and the second chip provided in some embodiments of the present application is shown. Figure 3 As shown, Figure 3 The module with shadows is the Pass module, that is, the module does not execute the corresponding steps. AP is the first chip, SOC is the second chip, the first camera module is 1×sensor, and the second camera module is 2×sensor. AP performs ISP processing on the 1×sensor raw image collected by the first camera module to obtain the first image data. Among them, the first image data includes 1×stats and 1×Metadata. AP transmits the first image data to SOC, and SOC sends the first image data corresponding to 1× to the AE algorithm for processing. The algorithm performs linear addition fusion and synchronization on the first image data combined with 1×Tuning parameters and 2×Tuning parameters. Among them, the convergence part is only processed in the 1×AE algorithm. The second exposure data obtained by convergence, after the algorithm processing is completed, the first exposure parameters corresponding to the first camera module and the second exposure parameters corresponding to the second camera module are generated respectively. The exposure parameters include exposure gain and exposure time. Among them, 1×Metering is the metering process in the automatic exposure algorithm, which is used to obtain the corresponding exposure data, 1×Convergence is the convergence process in the automatic exposure algorithm, which is used to perform convergence processing on the exposure data, and 1×Arbitration is the decision-making process in the automatic exposure algorithm, which is used to generate exposure parameters according to the exposure data after convergence processing. The first image data of the first camera module is obtained, and the first image data is only converged in the automatic exposure algorithm corresponding to the first camera module, which further improves the smoothness of brightness convergence, and the second camera module does not need to transmit the image data collected by itself to the second chip, which further reduces the energy consumption required for the processing process. Based on this, the first exposure parameters and the second exposure parameters corresponding to the first camera module and the second camera module are generated, which further improves the consistency of the brightness of the preview image collected by the first camera module and the preview image collected by the second camera module, making the brightness change of the zoom process smoother, reducing the degree of brightness change of the preview picture when the user adjusts the shooting focal length, and solving the problem of sudden brightness change of the preview picture during the zoom process. The first chip is only used to acquire image data without performing corresponding calculations, and the first exposure parameter and the second exposure parameter are generated in the second chip, which further saves energy consumption and improves the operating stability of the electronic device.

[0061] In the embodiment of the present application, the first chip is only used to obtain the image data collected by the first camera module and the second camera module, and the automatic exposure algorithm is run in the second chip to generate the corresponding first exposure parameter and second exposure parameter, which shares the power consumption of the first chip end, thereby saving the energy consumption of the electronic device. In the case where the first chip is the main chip of the electronic device, the stability of the operation of the electronic device can also be improved.

[0092] Furthermore, the processor 610 is used to obtain first exposure data according to first image data captured by the first camera module.

[0093] In the embodiment of the present application, by using the image statistics and metadata of the first image data captured by the first camera module as the first exposure data, there is no need to obtain the image data captured by the second camera module, and there is no need to perform corresponding processing on the image data captured by the second camera module, thereby further reducing the power consumption required during the shooting process of the electronic device.

[0096] The processor 610 is configured to perform linear addition fusion on the third exposure data and the fourth exposure data to obtain the first exposure data.

[0097] In an embodiment of the present application, the first exposure data is obtained by linearly adding and fusing the third exposure data of the first image data and the fourth exposure data of the second image data, thereby further improving the stability of the metering process, and the subsequent convergence processing of the first exposure data is only performed in the first automatic exposure algorithm corresponding to the first camera module, which can improve the brightness convergence stability of the camera module switching process.

[0098] Further, the processor 610 is used to obtain a first effect tuning parameter corresponding to the first camera module, and obtain a second effect tuning parameter corresponding to the second camera module;

[0099] The processor 610 is used to configure the exposure algorithm of the first camera module through the first effect tuning parameter and the second effect tuning parameter to update the exposure algorithm parameters of the first camera module.

[0100] In an embodiment of the present application, after obtaining the first effect tuning parameters and the second effect tuning parameters, the above two effect tuning parameters are configured into the exposure algorithm of the first camera module, thereby updating the exposure algorithm parameters corresponding to the first camera module, so that the subsequent convergence processing of the first exposure data through the exposure algorithm parameters of the first camera module is more accurate, and the converged second exposure data is further matched with the first camera module, thereby improving the smoothness of brightness convergence.
