[0020] The following is in conjunction with the appendix Figures 1 to 6 The present application provides a detailed description of the shooting method, shooting device, electronic device and readable storage medium provided in the embodiments of this application through specific implementation methods and application scenarios.

[0021] In some embodiments of this application, a shooting method is provided, applied to an electronic device, the electronic device including a first camera module and a second camera module. Figure 1 A flowchart illustrating the imaging method provided in some embodiments of this application is shown. For example... Figure 1 As shown, the shooting methods include:

[0022] Step 102: Acquire the first exposure data during the zooming process of the electronic device;

[0023] The first exposure data is the exposure data determined based on image data acquired by at least one of the first and second camera modules;

[0024] In this embodiment of the application, the electronic device includes a first camera module and a second camera module for acquiring image data at different focal lengths. During the zooming process of the electronic device, the electronic device takes pictures through at least one of the first camera module and the second camera module, and determines the first exposure data through the acquired image data.

[0025] Step 104: The first exposure data is converged using the exposure algorithm parameters of the first exposure module to obtain the 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 the corresponding exposure algorithm parameters.

[0027] In this embodiment, the first exposure data is converged using the exposure algorithm parameters of the first camera module. This ensures that the first exposure data, whether generated from image data acquired by the first camera module or image data acquired by the second camera module, is converged using the exposure algorithm parameters of the first camera module. Consequently, the converged second exposure data is the second exposure data that has been converged based on the exposure algorithm parameters of the first camera module, thus matching the second exposure data with the first camera module and improving the smoothness of brightness convergence.

[0028] Step 106: Calculate the first exposure parameters and the second exposure parameters based on the second exposure data;

[0029] For example, both the first and second exposure parameters include exposure gain and exposure time. Both exposure gain and exposure time are outputs of the automatic exposure (AE) algorithm.

[0030] Step 108: Control the first camera module to expose according to the first exposure parameters, and control the second camera module to expose according to the second exposure parameters.

[0031] In this embodiment, the second exposure data is the converged exposure data, the first exposure parameter is the exposure parameter to be configured in the first camera module (i.e., the first camera module exposes using the first exposure parameter), and the second exposure parameter is the exposure parameter to be configured in the second camera module (i.e., the second camera module exposes using the second exposure parameter). Since both the first and second exposure parameters are generated based on the second exposure data, and the second exposure data is the exposure data converged only through the exposure algorithm parameters corresponding to the first camera module, the consistency of brightness between the preview image acquired by the first camera module using the first exposure parameter and the preview image acquired by the second camera module using the second exposure parameter is improved during 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. This results in a smoother brightness transition process in the preview image displayed when the user adjusts the shooting focal length.

[0032] In this embodiment, when a user zooms using an electronic device, the electronic device can obtain first exposure data determined by image data collected by at least one of the first and second camera modules. It then converges the first exposure data using the exposure algorithm parameters corresponding to the first camera module to obtain second exposure data, improving the smoothness of brightness convergence. Based on this second exposure data, first and second exposure parameters corresponding to the first and second camera modules are generated, further improving the consistency of brightness between the preview images collected by the first and second camera modules. This makes brightness changes during zooming smoother, reduces the degree of brightness change in the preview image when the user adjusts the shooting focal length, and solves the problem of sudden brightness changes in the preview image during zooming.

[0033] In some embodiments of this application, the exposure data includes image statistics and metadata, and obtaining the first exposure data includes: obtaining the first exposure data based on the first image data collected by the first camera module.

[0034] In this embodiment, the exposure data includes image statistics (stats) and metadata. In determining the first exposure data using the first image data, it is necessary to obtain the image statistics and metadata of the first image data, and then use the image statistics and metadata to determine the first exposure data.

[0035] For example, after acquiring the first image data, image statistics and metadata in the first image data are acquired, and the acquired image statistics and metadata are determined as the first exposure data.

[0036] In this embodiment of the application, during the zooming process of the electronic device, the processor acquires the first image data collected by the first camera module, and acquires the image statistics data and metadata in the first image data as the first exposure data.

[0037] It should be noted that since only the image statistics and metadata from the first image data are used as the first exposure data, there is no need to activate the second camera module. For example, when the electronic device is detected to be zooming, the second camera module is controlled to stop operating, reducing the power consumption of the electronic device during shooting.

[0038] In this embodiment, by using the image statistics data and metadata of the first image data collected by the first camera module as the first exposure data, it is not necessary to acquire the image data collected by the second camera module, nor is it necessary to process the image data collected by the second camera module, thus further reducing the power consumption required by the electronic device during shooting.

[0039] In some embodiments of this application, the exposure data includes image statistics data and metadata. Obtaining the first exposure data includes: determining the third exposure data based on the first image data collected by the first camera module; determining the fourth exposure data based on the second image data collected 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 this embodiment, the exposure data includes image statistics and metadata. The image statistics and metadata from the first image data are obtained to get the third exposure data corresponding to the first camera module. The image statistics and metadata from the second image data are also obtained to get the fourth exposure data corresponding to the second camera module. The third and fourth exposure data are then linearly added together to obtain the first exposure data.

[0041] In this embodiment, the first exposure data is the exposure data obtained by linearly adding and fusing the third exposure data corresponding to the first image data and the fourth exposure data corresponding to the second image data. This enables the metering data corresponding to the first camera module and the second camera module to be fused and transitioned, thereby improving the adaptability of the first exposure data with the first camera module and the second camera module and improving the stability of metering.

[0042] In this embodiment of the application, during the zooming process of the user-controlled electronic device, the first image data collected by the first camera module and the second image data collected by the second camera module are acquired, 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 the first exposure data.

[0043] For example, the first exposure data is calculated using the following relationship (1):

[0044]

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

[0046] For example, in the case 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 using the above relationship (1) to obtain the first exposure data.

[0047] It should be noted that the weights are related to 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 this embodiment, 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, which further improves the stability of the metering process. Furthermore, 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 this application, the shooting method further includes:

[0050] Obtain the first effect optimization parameters corresponding to the first camera module, and obtain the second effect optimization parameters corresponding to the second camera module;

[0051] The exposure algorithm parameters of the first camera module are updated by configuring the first effect tuning parameters and the second effect tuning parameters into the exposure algorithm of the first camera module.

[0052] In this embodiment, the first camera module corresponds to a first effect tuning parameter, and the second camera module corresponds to a second effect tuning parameter. For example, the effect tuning parameter is a tuning parameter.

[0053] In this embodiment, after obtaining the first effect tuning parameter and the second effect tuning parameter, both of 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. This makes the subsequent convergence processing of the first exposure data through the exposure algorithm parameters of the first camera module more accurate, and further makes the converged second exposure data match the first camera module, improving the smoothness of brightness convergence.

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

[0055] When the first chip receives the third image data, it calculates the image statistics and metadata of the third image data. The third image data includes at least one of the image data acquired by the first camera module and the image data acquired by the second camera module. The first chip transmits the image statistics and metadata of the third image data to the second chip. The second chip performs exposure convergence processing on the image statistics and metadata of the third image data.

[0056] In this embodiment, the third image data is the image data acquired by the first chip at the first camera module and / or the second camera module. The third image data can 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 can be the image data acquired by the first camera module, or it can be 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. 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. The second chip can determine first exposure data based on the third image data and perform subsequent steps to determine first exposure parameters and second exposure parameters based on the first exposure data.

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

[0059] Figure 2 This application shows one of the structural block diagrams of the first chip and the second chip provided in some embodiments, such as... Figure 2As shown, the AP is the first chip, the SOC is the second chip, the first camera module has 1×sensor, and the second camera module has 2×sensor. The AP performs Image Signal Processing (ISP) on the 1×sensor raw image acquired by the first camera module and the 2×sensor raw image acquired by the second camera module to obtain first image data and 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 and second image data to the SOC. The SOC then feeds the first and second image data corresponding to the 1× and 2× focal lengths into the automatic exposure algorithm for processing. Internally, the algorithm performs linear addition and fusion of the first and second image data based on the brightness difference between 1× and 2× focal lengths, combined with their respective tuning parameters, and synchronizes them. The convergence part is processed only within the 1× automatic exposure algorithm. After the algorithm finishes processing the converged second exposure data, it generates the first exposure parameters for the first camera module and the second exposure parameters for the second camera module, respectively. Both exposure parameters include exposure gain and exposure time. Specifically, 1×Metering and 2×Metering are the metering processes in the automatic exposure algorithm used to acquire the corresponding exposure data; 1×Convergence and 2×Convergence are the convergence processes in the automatic exposure algorithm used to converge the exposure data; and 1×Arbitration and 2×Arbitration are the decision processes in the automatic exposure algorithm used to generate exposure parameters based on the converged exposure data. The system acquires first image data from the first camera module and second image data from the second camera module. The exposure data corresponding to the first and second image data is then converged only within the automatic exposure algorithm corresponding to the first camera module, improving the smoothness of brightness convergence. Based on this, first and second exposure parameters corresponding to the first and second camera modules are generated. This further improves the consistency of brightness between the preview images captured by the first and second camera modules, making brightness changes during zooming smoother and reducing the degree of brightness change in the preview image when the user adjusts the shooting focal length. This solves the problem of sudden brightness changes in the preview image during zooming. The first chip is used to acquire image data but does not perform related automatic exposure algorithm processing. The automatic exposure algorithm is only run in the second chip to generate the first and second exposure parameters, thus sharing the power consumption of the first chip and maintaining the overall operational stability of the electronic device.

[0060] Figure 3 This application shows two structural block diagrams of the first chip and the second chip provided in some embodiments, such as... Figure 3 As shown, Figure 3 The modules marked with shaded areas are Pass modules, meaning these modules do not execute the corresponding steps. The AP is the first chip, the SOC is the second chip, the first camera module has 1×sensor, and the second camera module has 2×sensor. The AP performs ISP processing on the 1×sensor raw image acquired by the first camera module to obtain the first image data. This first image data includes 1×stats and 1×Metadata. The AP transmits the first image data to the SOC, which then sends the corresponding 1×first image data to the AE algorithm for processing. The algorithm combines the first image data with 1×Tuning parameters and 2×Tuning parameters through linear addition fusion and synchronization. The convergence part is processed only within the 1×AE algorithm. The converged second exposure data, after processing by the algorithm, generates the first exposure parameters corresponding to the first camera module and the second exposure parameters corresponding to the second camera module. Both exposure parameters include exposure gain and exposure time. Among them, 1×Metering is the metering process in the automatic exposure algorithm, used to acquire the corresponding exposure data; 1×Convergence is the convergence process in the automatic exposure algorithm, used to converge the exposure data; and 1×Arbitration is the decision processing process in the automatic exposure algorithm, used to generate exposure parameters based on the converged exposure data. The first image data of the first camera module is acquired, and convergence is performed only on the automatic exposure algorithm corresponding to the first camera module, further improving the smoothness of brightness convergence. Furthermore, the second camera module does not need to transmit its acquired image data to the second chip, further reducing the energy consumption required for processing. Based on this, first and second exposure parameters corresponding to the first and second camera modules are generated, further improving the consistency of brightness between the preview images acquired by the first and second camera modules. This makes brightness changes during zooming smoother, reduces the degree of brightness change in the preview image when the user adjusts the shooting focal length, and solves the problem of sudden brightness changes in the preview image during zooming. The first chip is only used to acquire image data and does not perform any calculations. The first and second exposure parameters are generated in the second chip, which further saves energy and improves the operational stability of the electronic device.

[0061] In this embodiment, the first chip is only used to acquire image data collected by the first and second camera modules, and the automatic exposure algorithm is run in the second chip to generate corresponding first and second exposure parameters, thus sharing the power consumption of the first chip and saving energy consumption of the electronic device. When the first chip is the main chip of the electronic device, it can also improve the stability of the electronic device's operation.

[0062] The shooting method provided in this application can be executed by a shooting device. This application uses a shooting device executing the shooting method as an example to illustrate the shooting device provided in this application.

[0063] In some embodiments of this application, a shooting device is provided, applied to an electronic device including a first camera module and a second camera module. Figure 4 Schematic block diagrams of imaging devices provided in some embodiments of this application are shown. For example... Figure 4 As shown, the imaging device 400 includes:

[0064] The acquisition module 402 is used to acquire first exposure data during the zooming process of the electronic device. The first exposure data is the exposure data determined based on the image data collected by at least one of the first camera module and the second camera module.

[0065] Processing module 404 is used to perform convergence processing on the first exposure data using the exposure algorithm parameters of the first camera module to obtain the second exposure data;

[0066] Processing module 404 is used to calculate the first exposure parameters and the second exposure parameters based on the second exposure data;

[0067] The control module 406 is used to control the first camera module to expose according to the first exposure parameters and to control the second camera module to expose according to the second exposure parameters.

[0068] In this embodiment, when a user zooms using an electronic device, the electronic device can acquire first exposure data determined by image data collected by at least one of the first and second camera modules. It then converges the first exposure data using the exposure algorithm parameters corresponding to the first camera module to obtain second exposure data, improving the smoothness of brightness convergence. Based on this second exposure data, first and second exposure parameters corresponding to the first and second camera modules are generated, further improving the consistency of brightness between the preview images collected by the first and second camera modules. This makes brightness changes during zooming smoother, reduces the degree of brightness change in the preview image when the user adjusts the shooting focal length, and solves the problem of sudden brightness changes in the preview image during zooming.

[0069] In some embodiments of this application, the processing module 404 is used to obtain first exposure data based on the first image data collected by the first camera module.

[0070] In this embodiment, by using the image statistics data and metadata of the first image data collected by the first camera module as the first exposure data, it is not necessary to acquire the image data collected by the second camera module, nor is it necessary to process the image data collected by the second camera module, thus further reducing the power consumption required by the electronic device during shooting.

[0071] In some embodiments of this application, the processing module 404 is used to determine the third exposure data based on the first image data acquired by the first camera module;

[0072] Processing module 404 is used to determine fourth exposure data based on the second image data acquired by the second camera module;

[0073] Processing module 404 is used to perform linear addition and fusion of the third exposure data and the fourth exposure data to obtain the first exposure data.

[0074] In this embodiment, 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, which further improves the stability of the metering process. Furthermore, 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.

[0075] In some embodiments of this application, the acquisition module 402 is used to acquire the first effect optimization parameters corresponding to the first camera module and the second effect optimization parameters corresponding to the second camera module;

[0076] The processing module 404 is configured to update the exposure algorithm parameters of the first camera module by configuring the first effect optimization parameters and the second effect optimization parameters to the exposure algorithm of the first camera module.

[0077] In this embodiment, after obtaining the first effect tuning parameter and the second effect tuning parameter, both of 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. This makes the subsequent convergence processing of the first exposure data through the exposure algorithm parameters of the first camera module more accurate, and further makes the converged second exposure data match the first camera module, improving the smoothness of brightness convergence.

To avoid repetition, they will not be described again here.

[0083] It should be noted that the electronic devices in the embodiments of this application include the aforementioned mobile electronic devices and non-mobile electronic devices.

[0084] Figure 6 A schematic diagram of the hardware structure of an electronic device to implement an embodiment of this application.

[0085] The electronic device 600 includes, but is not limited to, components such as: radio frequency unit 601, network module 602, audio output unit 603, input unit 604, sensor 605, display unit 606, user input unit 607, interface unit 608, memory 609, and processor 610.

[0086] Those skilled in the art will understand that the electronic device 600 may also include a power supply (such as a battery) for supplying power to various components. The power supply may be logically connected to the processor 610 through a power management system, thereby enabling functions such as managing charging, discharging, and power consumption through the power management system. Figure 6 The electronic device structure shown does not constitute a limitation on the electronic device. The electronic device may include more or fewer components than shown, or combine certain components, or have different component arrangements, which will not be elaborated here.

[0087] The processor 610 is used to acquire first exposure data during the zooming process of the electronic device. The first exposure data is exposure data determined based on image data acquired by at least one of the first and second camera modules.

[0088] The processor 610 is used to converge the first exposure data using the exposure algorithm parameters of the first camera module to obtain the second exposure data;

[0089] Processor 610 is used to calculate first exposure parameters and second exposure parameters based on second exposure data;

[0090] The processor 610 is used to control the first camera module to expose according to the first exposure parameters, and to control the second camera module to expose according to the second exposure parameters.

[0091] In this embodiment, when a user zooms using an electronic device, the electronic device can acquire first exposure data determined by image data collected by at least one of the first and second camera modules. It then converges the first exposure data using the exposure algorithm parameters corresponding to the first camera module to obtain second exposure data, improving the smoothness of brightness convergence. Based on this second exposure data, first and second exposure parameters corresponding to the first and second camera modules are generated, further improving the consistency of brightness between the preview images collected by the first and second camera modules. This makes brightness changes during zooming smoother, reduces the degree of brightness change in the preview image when the user adjusts the shooting focal length, and solves the problem of sudden brightness changes in the preview image during zooming.

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

[0093] In this embodiment, by using the image statistics data and metadata of the first image data collected by the first camera module as the first exposure data, it is not necessary to acquire the image data collected by the second camera module, nor is it necessary to process the image data collected by the second camera module, thus further reducing the power consumption required by the electronic device during shooting.

[0094] Furthermore, the processor 610 is used to determine the third exposure data based on the first image data acquired by the first camera module;

[0095] The processor 610 is used to determine the fourth exposure data based on the second image data acquired by the second camera module;

[0096] Processor 610 is used to perform linear addition and fusion of the third exposure data and the fourth exposure data to obtain the first exposure data.

[0097] In this embodiment, 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, which further improves the stability of the metering process. Furthermore, 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] Furthermore, the processor 610 is used to obtain the first effect optimization parameters corresponding to the first camera module and the second effect optimization parameters corresponding to the second camera module.

[0099] The processor 610 is configured to update the exposure algorithm parameters of the first camera module by configuring the first effect tuning parameters and the second effect tuning parameters to the exposure algorithm of the first camera module.
