[0028] 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.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. 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.

[0030] The following is a detailed description of the image data processing method provided by the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] like Figure 1 As shown, the embodiment of the present application provides a method for processing image data, including:

[0032] Step 101: Acquire target parameters, where the target parameters include at least one of a shooting scene and a camera mode.

[0033] Optionally, the shooting scenes include outdoor shooting scenes, indoor shooting scenes, character shooting scenes, landscape shooting scenes, moving object shooting scenes, etc.

[0034] Optionally, the camera mode includes a shooting mode, a video recording mode, a preview mode, etc.

[0035] In the embodiment of the present application, different shooting scenes or different camera modes can be set to correspond to different working modes. Based on the above target parameters, the shooting requirements can be determined, thereby determining whether the first image processor is required to perform image preprocessing on the image data collected by the camera.

[0036] Step 102: setting a working mode of a first image processor according to the target parameter, wherein the first image processor is connected to a first camera module and a second image processor of the electronic device respectively, and the working mode includes a first working mode or a second working mode;

[0037] Wherein, in the first working mode, the first image processor performs image preprocessing on the image data collected by the first camera module, and sends the image data after image preprocessing to the second image processor;

[0038] In the second working mode, the first image processor directly sends the image data collected by the first camera module to the second image processor.

[0039] The first image processor mentioned above can be described as a camera plug-in chip.

[0040] The second image processor includes an image signal processing module in an application processor of the electronic device. The image signal processing module can also be described as an image signal processor (ISP).

[0041] The first working mode can be described as a digital bypass (DBP) working mode. Figure 2 As shown, in the first working mode, the first camera module and the second image processor are respectively connected to the port physical layer (Port Physics Layer, PHY) of the first image processor. The first image processor performs image preprocessing on the image data sent by the first camera module through the image processing module and then sends it to the second image processor.

[0042] Optionally, the image preprocessing includes but is not limited to pixel correction and bad pixel correction of phase detection (PD) points.

[0043] The second working mode can be described as an analog bypass (ABP) working mode. Figure 3 As shown, in the second working mode, the first camera module and the second image processor are not connected to the PHY of the first image processor. At this time, the information in the double data rate (DDR) synchronous dynamic random access memory (SDRAM) and static random access memory (SRAM) inside the first image processor is not lost. Except for the CPU and the interface for maintaining communication, other peripherals and algorithm IPs stop working or enter low power consumption mode.

[0044] In an embodiment of the present application, the working mode of the first image processor is set according to the shooting scene and / or the camera mode, that is, it is determined according to the shooting scene and / or the camera mode whether the first image processor is required to perform image preprocessing on the image data collected by the camera, and when image preprocessing is not required, the image data collected by the camera is directly transmitted to the second image processor, thereby effectively reducing the power consumption of the first image processor, and there is no need to stop the image data output by the camera, and will not affect the normal preview, photo taking, and video recording of the camera.

[0045] Optionally, obtain target parameters, including:

[0046] When the first condition is met, obtaining the target parameter;

[0047] The first condition includes at least one of the following:

[0048] The first camera module of the electronic device is turned on;

[0049] The camera mode and / or shooting scene of the electronic device changes, wherein the second camera module is not connected to the camera external chip.

[0050] In an embodiment of the present application, the target parameters are acquired and the working mode of the first image processor is set based on the target parameters when it is detected that the first camera module of the electronic device is turned on and / or when it is detected that the camera mode and / or shooting scene of the electronic device has changed. Instead of acquiring the target parameters in real time, this is beneficial to energy saving of the electronic device.

[0051] Optionally, after setting the working mode of the first image processor, the method further includes:

[0052] Detecting whether the target parameter changes;

[0053] When a change in the target parameter is detected, the working mode of the first image processor is switched according to the changed target parameter.

[0054] For example, Figure 4 As shown, the working mode of the first image processor is first set to the second working mode according to the target parameters. If it is subsequently detected that the target parameters have changed, and the working mode corresponding to the changed target parameters is the first working mode, the working mode of the first image processor is switched from the second working mode to the first working mode, thereby achieving energy saving of the first image processor.

[0055] In an embodiment of the present application, the first image processor can switch between the first working mode and the second working mode according to the target parameters, rather than working in a mode of always pre-processing the image data collected by the camera module, thereby saving energy consumption of the first image processor and saving memory of the first image processor.

[0056] Optionally, switching the working mode of the first image processor includes:

[0057] A working mode switching instruction is sent to the first image processor through a driving layer of the electronic device.

[0058] In the embodiment of the present application, when the first image processor switches between the first working mode and the second working mode, Figure 5 As shown, the electronic device sends a working mode switching instruction to the driver layer, and then uses software to drive input / output operations (input / output control, ioctl) to send the working mode switching instruction to the first image signal processor. During the transmission of the working mode switching signaling, the camera module has been transmitting image data to the first image processor, that is, the above working mode switching process only needs to be performed inside the first image processor, and there is no need to stop the camera from outputting image data to the first image processor, which does not affect the normal preview, photo taking and video recording of the camera. Therefore, the above switching working mode can also be described as a seamless switching working mode.

[0059] Optionally, setting a working mode of the first image processor according to the target parameter includes:

[0060] Determine the working mode corresponding to the target parameter according to a preset corresponding relationship, wherein the preset corresponding relationship includes at least one of a first corresponding relationship and a second corresponding relationship, the first corresponding relationship is a corresponding relationship between a shooting scene and a working mode, and the second corresponding relationship is a corresponding relationship between a camera mode and a working mode;

[0061] The working mode corresponding to the target parameter is set as the working mode of the first image processor.

[0062] In the embodiment of the present application, the correspondence between different shooting scenes or different camera modes and the working modes is preset, so as to facilitate the subsequent determination of the working mode of the first image processor based on the correspondence.

[0063] Combine the following Figure 6 The overall process of the image data processing method of the embodiment of the present application is described.

[0064] like Figure 6 As shown, the processing method includes:

[0065] Step 1: Open the camera.

[0066] Step 2: Determine whether to turn on the first camera module connected to the first image processor.

[0067] Step 31: If the first camera module is turned on, determine whether the current shooting scene is a scene that requires a first image processor.

[0068] Specifically, it is determined based on the target parameters whether the first image processor is required to preprocess the image data collected by the first camera module. If necessary, it is determined that the current shooting scene is a scene requiring the first image processor. Otherwise, it is determined that the current shooting scene is not a scene requiring the first image processor.

[0069] Step 32: If the first camera module is not turned on, jump to step 5.

[0070] Step 41: If the current shooting scene is a scene that requires the first image processor, the working mode of the first image processor is set to the DBP working mode.

[0071] Step 42: If the current shooting scene is not a scene that requires the first image processor, the working mode of the first image processor is set to the ABP working mode.

[0072] Step 5: Turn on the camera preview mode.

[0073] Step 6: Determine whether the shooting scene or camera mode has changed.

[0074] Step 71: If a change occurs, jump to step 2.

[0075] Step 72: If no change occurs, maintain the current working mode.

[0076] In addition, when an instruction to exit the camera is received, the first image processor will be powered off.

[0077] In the embodiment of the present application, if the first image processor does not need to process image data in the current shooting scene, its working mode is set to the DBP mode, otherwise, it is set to the ABP working mode. Moreover, after detecting a change in the shooting scene or the camera mode, the working mode of the first image processor is reset, and seamless switching between the DBP working mode and the ABP working mode can be achieved.

[0082] Wherein, in the first working mode, the first image processor performs image preprocessing on the image data collected by the first camera module, and sends the image data after image preprocessing to the second image processor;

[0083] In the second working mode, the first image processor directly sends the image data collected by the first camera module to the second image processor.

[0092] Optionally, the fourth processing module is used to send a working mode switching instruction to the first image processor through a driving layer of the electronic device.

[0093] Optionally, the second processing module is used to:

[0094] Determine the working mode corresponding to the target parameter according to a preset corresponding relationship, wherein the preset corresponding relationship includes at least one of a first corresponding relationship and a second corresponding relationship, the first corresponding relationship is a corresponding relationship between a shooting scene and a working mode, and the second corresponding relationship is a corresponding relationship between a camera mode and a working mode;
