[0041] In order to better understand the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the drawings.

[0042] It should be clear that the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of protection of the present application.

[0043] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0044] In view of the problem of poor ISP image processing effect in the prior art, the embodiments of the present application provide an image processing method, which improves the processing effect of ISP.

[0045] Figure 1 A flow chart of an image processing method provided by an embodiment of the present application. The method can be applied to a smart phone or other terminal device with shooting function, such as Figure 1 As shown in the figure, the method can include:

[0046] In step 101, different processing parameters of the to-be-processed image are respectively stored in different software contexts, and the processing parameters include shooting processing parameters and preview processing parameters.

[0047] When the smart phone uses the photographing function, a plurality of continuous frames of original images can be obtained through the camera, and the to-be-processed image is one of the frames. After the to-be-processed image is processed by the ISP, the to-be-processed image is displayed on the screen of the smart phone. Before the user clicks the photographing button, the to-be-processed image displayed on the screen of the smart phone is a preview image, and the user can adjust the shooting angle or the shooting object according to the preview image to obtain an ideal shooting image. When the user clicks the photographing button, the smart phone determines the corresponding to-be-processed image in the internal as the shooting image. After the smart phone obtains a frame of to-be-processed image, the shooting processing parameters and the preview processing parameters of the frame of to-be-processed image can be determined, and the two parameters are stored in different software contexts SW-Context, for example, the shooting processing parameters are stored in a first SW-Context, and the preview processing parameters are stored in a second SW-Context, and the first SW-Context and the second SW-Context are any two of a plurality of SW-Contexts. Generally, the number of SW-Contexts is large, and two SW-Contexts can be configured to store the processing parameters for each frame of to-be-processed image.

[0048] In step 102, the image attribute of the to-be-processed image is determined, and the image attribute includes a shooting image corresponding to the shooting processing parameter or a preview image corresponding to the preview processing parameter.

[0049] For any frame of to-be-processed image, before the ISP processes the to-be-processed image, the smart phone determines the image attribute of the to-be-processed image, that is, determines whether the to-be-processed image is a preview image or a shooting image. The shooting image corresponds to the shooting processing parameter, and the preview image corresponds to the preview processing parameter.

[0050] In step 103, according to the image attribute, the software context storing the corresponding processing parameter is connected with the hardware context in an idle state.

[0051] When the to-be-processed image is determined as a shooting image, the SW-Context storing the shooting processing parameter is connected with the HW-Context in an idle state, and when the to-be-processed image is determined as a preview image, the SW-Context storing the preview processing parameter is connected with the HW-Context in an idle state. Taking the first SW-Context as an example, if the to-be-processed image is a shooting image, the smart phone will traverse the hardware context and determine any HW-Context in an idle state as a first HW-Context, and then dynamically associate the first SW-Context and the first HW-Context.

[0052] In step 104, the shooting processing parameter is sent to the hardware context storage, so that the image signal processor ISP acquires the shooting processing parameter from the hardware context and performs image processing on the to-be-processed image according to the shooting processing parameter.

[0053] Before the ISP processes the to-be-processed image, the smartphone sends the processing parameter corresponding to the to-be-processed image to the memory space associated with the HW-Context. The ISP can acquire the processing parameter from the memory space associated with the HW-Context and write it into the ISP hardware register. In subsequent image processing, the processing parameter is acquired from the ISP hardware register to process the to-be-processed image. After the image processing is completed, the smartphone deletes the dynamic association between the SW-Context and the HW-Context, so that the HW-Context reverts to the idle state. After the first SW-Context and the first HW-Context are dynamically associated, the first HW-Context becomes a non-idle state. After the image processing is completed, the smartphone deletes the dynamic association between the first SW-Context and the first HW-Context, and the first HW-Context reverts to the idle state. If the next to-be-processed image is a preview image, the HW-Context can be dynamically associated with the SW-Context storing the preview processing parameter. By releasing the hardware resources in time and updating the processing parameter of the next to-be-processed image in time, the smartphone can ensure that each to-be-processed image has independent processing parameters, thereby realizing frame-level control of the processing parameter of the to-be-processed image.

[0054] In an embodiment, after the smartphone acquires the to-be-processed image through the camera, the environmental data of the current environment can be acquired, and the preview processing parameter and the shooting processing parameter of the to-be-processed image can be determined according to the environmental data. For example, when the smartphone is switched from a dark environment to an environment with higher brightness, the corresponding processing parameter needs to be modified to weaken the influence of light on the to-be-processed image. Or, when the smartphone is shooting a night scene, the processing parameter also needs to be adjusted accordingly, such as adjusting the sharpness, color enhancement, etc.

[0055] In the embodiment of the present application, the SW-Context can realize the asynchronous processing of the processor and the ISP. After determining the processing parameters of the image to be processed, the processor of the smart phone can directly store the processing parameters to the SW-Context. When the ISP needs to obtain the processing parameters, the ISP does not need to directly interface with the processor, but only needs to obtain the processing parameters in the SW-Context. The processor and the ISP do not affect each other, the idle time is reduced, and the efficiency is improved. The SW-Context simultaneously saves the preview processing parameters and the shooting processing parameters, the smart phone can select the corresponding processing parameters according to the image properties of the image to be processed to process the image, the influence caused by the coupling of the preview processing parameters and the shooting processing parameters is reduced, and the display effect of the image on the screen is improved.

[0056] Figure 2 The flowchart of another image processing method provided by the embodiment of the present application is shown in FIG. 2. As shown in FIG. 2, the method can include the following steps. Figure 2

[0057] Step 201, determining the processing parameters.

[0058] The smart phone can determine the corresponding processing parameters according to the current environment. The aspects involved in the processing parameters can include automatic white balance, automatic focusing, automatic exposure, sharpness adjustment, color enhancement, and the like. With the change of the processing parameters, the image processed through the above process will have different effects.

[0059] Step 202, obtaining the SW-Context.

[0060] Step 203, storing the processing parameters to the SW-Context.

[0061] In the embodiment of the present application, the smart phone will configure a plurality of SW-Contexts. The SW-Contexts which do not store the processing parameters can be regarded as idle states, and the SW-Contexts which store the processing parameters can be regarded as non-idle states. The smart phone can obtain two SW-Contexts which respectively store the shooting processing parameters and the preview processing parameters in the plurality of idle state SW-Contexts.

[0062] Step 204, traversing the HW-Context.

[0063] Step 205, judging whether the current HW-Context is in the idle state.

[0064] If the current HW-Context is in the non-idle state, returning to step 204, if the current HW-Context is in the idle state, entering step 206.

[0065] ​Step 206, dynamically associate SW-Context with HW-Context.

[0066] The smart phone dynamically associates SW-Context storing corresponding processing parameters with HW-Context according to the image attribute of the image to be processed. Specifically, if the image to be processed is a shooting image, SW-Context storing shooting processing parameters is dynamically associated with HW-Context, and if the image to be processed is a preview image, SW-Context storing preview processing parameters is dynamically associated with HW-Context.

[0067] Step 207, write the processing parameters in SW-Context into the memory space associated with HW-Context.

[0068] The corresponding processing parameters are written into the memory space. There is a certain time interval between the processor generating the processing parameters and writing the processing parameters into the memory space associated with HW-Context. After the SW-Context is configured in the embodiment of the present application, the processor can save the processing parameters in the SW-Context, and then process other tasks, without waiting for the connection with HW-Context to be established, thereby improving the efficiency of the processor.

[0069] Step 208, start CFG module to carry the processing parameters to the ISO hardware register.

[0070] The CFG module is a module inside the ISP for carrying the processing parameters.

[0071] Step 209, ISP image processing.

[0072] Step 210, delete the dynamic association of SW-Context with HW-Context.

[0073] In the embodiment of the present application, after the connection between SW-Context and HW-Context is disconnected, the HW-Context restored to the idle state can establish a connection with other SW-Context to store the processing parameters of other images to be processed. The number of HW-Contexts is usually less than that of SW-Contexts, which is related to the hardware configuration of the ISP, while the number of SW-Contexts is a software level, which can not be limited by the hardware, and can be configured according to the specific requirements.

[0074] In the embodiment of the present application, the path of the processing parameters can be as follows Figure 3As shown, the processor generates processing parameters for each frame of the image to be processed based on environmental data, and then sends these parameters to the SW-Context for storage. Each frame of the image to be processed corresponds to two processing parameters (capture processing parameters and preview processing parameters). If the current image to be processed is determined to be a preview image, the preview processing parameters are sent to the HW-Context; if the current image to be processed is determined to be a captured image, the capture processing parameters are sent to the HW-Context. Finally, the processing parameters are transferred from the HW-Context to the ISP via the transfer module.

[0075] Figure 4 This is a schematic diagram of the structure of an image processing device provided in an embodiment of the present invention. Figure 3 As shown, the device may include: a processing module 410, a determining module 420, an association module 430, and a sending module 440.

[0076] The processing module 410 is used to store different processing parameters of the image to be processed into different software contexts. The processing parameters include shooting processing parameters and preview processing parameters.

[0077] The determining module 420 is used to determine the image attributes of the image to be processed. The image attributes include: the captured image corresponding to the capturing processing parameters, or the preview image corresponding to the preview processing parameters.

[0078] The association module 430 is used to establish a connection between the software context storing the corresponding processing parameters and the hardware context that is in an idle state, based on the image attributes.

[0079] The sending module 440 is used to send processing parameters to the hardware context storage so that the image signal processor (ISP) can obtain the processing parameters from the hardware context and perform image processing on the image to be processed according to the processing parameters.
