[0067] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0068] In the related art, during the shooting process, one of the multiple rear cameras (for example, rear camera 1) is always turned on. When the user adjusts the zoom and switches to other cameras, rear camera 1 remains on. At this time, two cameras with different field of views are working simultaneously. The electronic device will send the image data collected by both cameras to the 3A (AE, AWB, AF) algorithm for calculation to obtain a unified 3A result. At this time, the two cameras can obtain images with consistent brightness, color, and focus positions, thereby improving the visual experience and user experience when switching between multiple cameras. However, turning on both cameras simultaneously will increase the power consumption of the electronic device.

[0069] In the embodiments of the present disclosure, to address the above problems, by preventing the second sensor from outputting second image data, the power consumption of the second sensor is saved, thereby saving the power consumption of the electronic device while avoiding the problem of poor consistency of the images output by multiple cameras.

[0070] The method provided by the embodiments of the present disclosure is executed by an electronic device, which can be a device with multiple cameras such as a mobile phone, a tablet computer, or a smart home device.

[0071] Figure 1 is a flowchart of a shooting method shown according to an exemplary embodiment, which is executed by an electronic device. Refer to Figure 1 and the method includes the following steps:

[0072] Step S101: Perform data statistics on the first image data through the first ISP to obtain first statistical information. The first image data is collected by the first sensor, and the first sensor is the image sensor corresponding to the first camera.

[0073] Among them, the first camera is any one of the multiple rear cameras, and during the current shooting process, the first camera is the main camera; the first sensor is the image sensor corresponding to the first camera, and the image sensor can be a low-power CMOS (Complementary Metal-Oxide Semiconductor) sensor or other types of image sensors; the first ISP (Image Signal Processor) is the ISP that processes data related to the first camera.

[0074] For the first camera (main camera), after the first image data is collected by the first sensor, the first image data is transmitted to the first ISP, and then the first ISP performs data statistics on the first image data to obtain the first statistical information. Among them, the first image data includes information of multiple pixels. For example, the first image data includes information of the R (red), G (green), and B (blue) channels; the first statistical information includes the first AE (Auto Exposur) information, the first AWB (Auto White Balance) information, and the first AF (Auto Focus) information.

[0075] Step S102: Perform data statistics on the second image data through the second sensor to obtain the second statistical information. The second image data is collected by the second sensor, and the second sensor is the image sensor corresponding to the second camera.

[0076] Among them, the second camera is any one of multiple rear cameras and is different from the first camera. During the current shooting process, the second camera is the secondary camera; the second sensor is the image sensor corresponding to the second camera; the second ISP is the ISP that processes data related to the second camera.

[0077] As the secondary camera, the second image data is used as reference data for the first image data, and it is not necessary to output the second image data for image display. Moreover, since the data volume of the second image data is large, if the second sensor transmits the second image data, the required power consumption is large. Therefore, in the embodiments of the present disclosure, in order to reduce power consumption, the second sensor directly performs data statistics on the second image data to obtain the second statistical information, and then the second sensor only needs to transmit the second statistical information instead of the second image data. Among them, the second image data includes information of multiple pixels; the second statistical information includes the second AE information, the second AWB information, and the second AF information.

[0078] Step S103: Process based on the first statistical information and the second statistical information to obtain updated parameters.

[0079] After obtaining the first statistical information and the second statistical information, process based on the first statistical information and the second statistical information to obtain updated parameters, which are used to represent the AE information, AWB information, and AF information to be updated for the first image data.

[0080] Step S104: Perform image display based on the updated parameters and the first image data.

[0081] Update the first image data based on the updated parameters, and then perform image display based on the updated image data.

[0082] In the method provided by the embodiments of the present disclosure, the first camera and the second camera are turned on during the shooting process. The first image data corresponding to the first camera is sent by the first sensor to the first ISP and then processed by the first ISP, while the second image data corresponding to the second camera is directly processed by the second sensor. Although two cameras are turned on, the second sensor no longer outputs the second image data, but only outputs the content of the statistical information, reducing the amount of data output and saving the power consumption of the second sensor. Thus, while avoiding the problem of poor consistency of the images output by multiple cameras, the power consumption of the electronic device can be saved.

[0083] In some embodiments, when it is determined that the first camera is the main camera, the first sensor and the first ISP are controlled to be in the first working mode; when it is determined that the second camera is the secondary camera, the second sensor and the second ISP are controlled to be in the second working mode, and the first working mode and the second working mode are different. Among them, the first working mode means that the image sensor transmits the acquired image data to the ISP, and the ISP processes the image data and forwards the processed information; the second working mode means that the image sensor directly processes the acquired image data, and then transmits the processed information to the ISP, and the ISP directly forwards the processed information. On this basis, the shooting process will be described in detail through the Figure 2 embodiments shown below.

[0084] Figure 2 is a flowchart of a shooting method shown according to an exemplary embodiment, which is executed by an electronic device. Refer to Figure 2 and the method includes the following steps:

[0085] Step S201, acquire first image data through the first sensor and transmit the first image data to the first ISP through the first sensor.

[0086] For the first sensor, the first sensor is in the first working mode. After the first sensor acquires the first image data, it directly transmits the first image data to the first ISP without processing the first image data.

[0087] Step S202, perform data statistics on the first image data through the first ISP to obtain first statistical information and save the first statistical information to the first storage area.

[0088] For the first ISP, after receiving the first image data transmitted by the first sensor, the first ISP performs data statistics on the first image data to obtain first statistical information. That is, the first ISP extracts first AE information, first AWB information, and first AF information from the first image data. Then, the first statistical information is stored in the first storage area, which is convenient for directly reading the first statistical information from the first storage area when the first statistical information needs to be processed later. Here, the first storage area is any area in the electronic device for storing information.

[0089] It should be noted that in the embodiments of the present disclosure, there is no limitation on the data statistics method when obtaining statistical information.

[0090] Step S203, collect second image data through the second sensor, and perform data statistics on the second image data to obtain second statistical information.

[0091] For the second sensor, the second sensor is in the second working mode. After collecting the second image data, the second sensor directly performs data statistics on the second image data to obtain second statistical information. That is, the second sensor extracts second AE information, second AWB information, and second AF information from the second image data.

[0092] In some embodiments, the second sensor downsamples the second image data to obtain the third image data after downsampling; the second sensor performs data statistics on the third image data after downsampling to obtain second statistical information. Since after downsampling the second image data, the amount of data that the second sensor needs to process is reduced, but it does not affect the FOV (Field of View) of the sampled image, and it also does not affect the pixel size. Performing data statistics on the third image data after downsampling has the same result as performing data statistics on the second image data. Therefore, performing data statistics on the third image data can further reduce the power consumption of the second sensor while ensuring that the second statistical information remains unchanged.

[0093] For example, referring to Figure 3 the schematic diagram of image downsampling shown in Figure 3 is to perform 1 / 4 downsampling on the image. Again, for example, referring to Figure 4 the schematic diagram of image downsampling shown in Figure 4 is to perform 1 / 16 downsampling on the image. Figure 3 And Figure 4 the black squares in

[0094] Step S204: Transmit the second statistical information to the second ISP through the second sensor, and save the second statistical information to the second storage area.

[0095] The second ISP only needs to save the second statistical information to the second storage area, so that when the second statistical information needs to be processed later, the second statistical information can be directly read from the second storage area. Herein, the second storage area is any area in the electronic device used for storing information, and the second storage area and the first storage area may be the same storage area or different storage areas.

[0096] In the embodiments of the present disclosure, for the second ISP, there is no need to process the second image data, which saves memory and bus bandwidth, and reduces the power consumption of the second ISP, that is, reduces the power consumption of the electronic device.

[0097] It should be noted that the embodiments of the present disclosure are only described by taking the execution of steps S201 and S202 first, and then the execution of steps S203 and S204 as an example. In the actual execution process, steps S203 and S204 may be executed first, and then steps S201 and S202, or steps S201 - S202 and steps S203 - S204 may be executed simultaneously.

[0098] Step S205: Invoke the first preset algorithm to process the second statistical information to obtain the third statistical information.

[0099] Wherein, the first preset algorithm is a pre - set 3A algorithm, and the 3A algorithm includes an AE algorithm, an AWB algorithm, and an AF algorithm. In the embodiments of the present disclosure, no limitation is imposed on the specific algorithms adopted. The first preset algorithm is used to read the second statistical information from the second storage area, and then process the second statistical information to obtain the third statistical information, and the third statistical information is used to represent the AE information, AWB information, and AF information to be updated of the second image data.

[0100] In some embodiments, since the second statistical information is processed by the second sensor, while the first statistical information is processed by the first ISP, and the modules for processing the second statistical information and the first statistical information are different, the second statistical information and the first statistical information may not match in terms of format, content, etc. Therefore, when invoking the first preset algorithm to process the second statistical information, the second statistical information also needs to be adapted, that is, the processed third statistical information needs to be statistical information that matches the first statistical information in terms of format, content, etc.

[0101] In some embodiments, the third statistical information is transmitted to the second sensor, and based on the third statistical information, the second image data is updated.

[0102] Step S206: Invoke a second preset algorithm to process the first statistical information and the third statistical information to obtain update parameters.

[0103] Among them, the second preset algorithm is a pre-set 3A algorithm, which is different from the first preset algorithm. The second preset algorithm is used to read the first statistical information from the first storage area, and then process the first statistical information and the third statistical information to obtain update parameters. Among them, the update parameters are used to characterize the AE information, AWB information, and AF information to be updated for the first image data.

[0104] Step S207: Update the first image data based on the update parameters to obtain target image data.

[0105] In the embodiments of the present disclosure, it is necessary to transmit the update parameters to the first sensor, and then update the first image data based on the update parameters to obtain target image data.

[0106] Step S208: Perform image display based on the target image data.

[0107] Transmit the target image data to the display module, and perform image display through the display module.

[0108] In some embodiments, the above shooting process can be as Figure 5 shown. Refer to Figure 5 , the first sensor transmits the first image data to the first ISP. The function of the first ISP is to process images. The first ISP performs data statistics on the first image data to obtain the first statistical information, and then transmits the first statistical information to the first 3A algorithm. The second sensor performs data statistics on the second image data to obtain the second statistical information, and then transmits the second statistical information to the second ISP. The second ISP is in a pass-through mode, that is, the second ISP transmits the second sensor to the second 3A algorithm. The second 3A algorithm is used to process the second statistical information to obtain the third statistical information, and then transmits the third statistical information to the first 3A algorithm. The first 3A algorithm processes the first statistical information and the third statistical information to obtain update parameters, and transmits the update parameters to the first sensor. The first sensor updates the first image data, and then transmits the updated target image data to the first ISP. The first ISP sends the target image data to the display screen, and the display screen displays the image.

[0109] It should be noted that the above implementation manner is described by taking the shooting process of one image as an example. For other images in the shooting process, the same implementation manner is used for processing to reduce the power consumption of the electronic device.

[0110] In addition, in a related technology, in order to save power consumption, the frame rate of the rear camera that is always on is reduced. However, a reduced frame rate means a lower update frequency of 3A statistics, which will reduce the 3A convergence speed. For example, refer to Figure 6 the schematic diagram of the shooting process in the related technology shown in the figure. The main camera captures two images, and the secondary camera (the rear camera that is always on) captures one image. The frame rate of the secondary camera is relatively low. The two images captured by the main camera need to refer to the same image captured by the secondary camera for 3A synchronization.

[0111] In the embodiments of the present disclosure, since both the second sensor and the second ISP have reduced power consumption, there is no need to save power in terms of frame rate. That is, the frame rate of the first camera can be the same as that of the second camera, thereby increasing the iteration speed of 3A and improving the 3A convergence speed. Moreover, the main camera no longer relies on the image captured by the secondary camera for 3A synchronization, but directly uses the statistics of the secondary camera for 3A synchronization. For example, refer to Figure 7 the schematic diagram of the shooting process shown in the figure. The main camera captures one image, and the secondary camera also captures one image. The frame rates of the main camera and the secondary camera are the same. The image captured by the main camera refers to the statistical information corresponding to the image captured by the secondary camera for 3A synchronization.

[0112] For the method provided in the embodiments of the present disclosure, for the second sensor, the first camera and the second camera are turned on during the shooting process. The first image data corresponding to the first camera is sent from the first sensor to the first ISP and then processed by the first ISP, while the second image data corresponding to the second camera is directly processed by the second sensor. Although two cameras are turned on, the second sensor no longer outputs the second image data, but only outputs the content of the statistics, reducing the amount of data output and saving the power consumption of the second sensor. Moreover, the second sensor downsamples the second image data and performs data statistics on the downsampled image data, further saving the power consumption of the second sensor. Thus, while avoiding the problem of poor consistency of images output by multiple cameras, the power consumption of the electronic device can be saved.

[0113] For the second ISP, the second ISP no longer processes the second image data, saving memory and bus bandwidth and further reducing the power consumption of the electronic device.
