In this case, how to configure the multiple hardware modules is a problem to be solved. SUMMARY

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] The Linux kernel, as the core of the open-source operating system, is responsible for managing hardware resources, providing system call interfaces, scheduling processes, handling interrupts, and other low-level functions. The Linux kernel acts as a bridge between applications and hardware; applications indirectly operate the hardware through system calls provided by the kernel, without directly interacting with hardware registers. Among its components, Video for Linux 2 (V4L2) is a standardized subsystem framework for video devices within the Linux kernel, providing a unified framework for driver development and application programming for video devices.

[0033] Optionally, V4L2 breaks down a complex video hardware component into multiple independent sub-devices (subdevices), each responsible for a single function; each sub-device is essentially a hardware module. For example, V4L2 uses structures such as v4l2-subdev to abstract sub-devices such as image sensors, camera serial interface (CSI) receivers, and image signal processors (ISPs), providing standard configuration and control interfaces for upper-layer applications.

[0034] The image sensor is the core device that converts optical images into electronic signals, used to acquire raw image data and respond to exposure or focus control. The CSI receiver is responsible for receiving and parsing image data. The ISP is a key processing unit in the camera system, responsible for data processing and synthesis. For example, the ISP performs a series of processes on the raw image data output by the image sensor, such as noise reduction, color interpolation, white balance, gamma correction, and HDR synthesis.

[0035] High Dynamic Range (HDR) imaging technology aims to solve the problem of overexposure in highlight areas or underexposure in shadow areas in scenes with high contrast between light and dark. Among them, sensor-level HDR technology includes, but is not limited to, the following two functions: (1) multi-exposure temporal synthesis: the image sensor continuously captures multiple frames of images with different exposure times in a very short period of time, providing wider dynamic range information for subsequent processing; (2) single-frame spatial synthesis: through special design at the pixel level, signals of different exposure levels are captured in one exposure. Enabling HDR mode usually means higher data throughput, more complex processing flow and higher system power consumption.

[0036] However, in HDR mode, if the HDR configurations of multiple hardware modules in the image processing pipeline are out of sync, it will lead to image processing abnormalities. For example, because the ISP needs to perform complex algorithms such as multi-frame alignment and fusion, the ISP's HDR configuration must be precisely matched with the image sensor's HDR output mode; otherwise, it will result in synthesis failure, image artifacts, or image quality degradation.

[0037] In other words, changing the HDR mode requires synchronized updates to the HDR configurations of the image sensor, CSI receiver, and ISP. This synchronized HDR configuration update means that the image sensor, CSI receiver, and ISP must coordinate and align key parameters to ensure that multi-exposure data can be correctly transmitted and fused. Optionally, HDR modes include a two-frame composite HDR mode (HDR_X2 mode), a three-frame composite HDR mode (HDR_X3 mode), and an HDR-off mode (i.e., NO_HDR mode).

[0038] HDR_X2 mode refers to an HDR implementation using a two-stage combination of "short exposure + long exposure". The short exposure frame is specifically used to capture details in highlight areas, avoiding overexposure; the long exposure frame focuses on shadow areas, thus supplementing shadow textures. During ISP compositing, the pixels of the short exposure frame are used for highlight areas, and the pixels of the long exposure frame are used for shadow areas. Then, the intermediate transition area is blended. HDR_X3 mode refers to an HDR implementation using a three-stage combination of "short exposure + medium exposure + long exposure". In addition to the short exposure frame preserving highlights and the long exposure capturing shadows, the newly added medium exposure frame is specifically responsible for restoring the normal brightness details of the main subject. During ISP compositing, the short exposure frame and the medium exposure frame are first combined to create a highlight enhancement image, which is then blended with the long exposure frame, significantly reducing the abruptness of the transition between bright and dark areas.

[0039] Taking HDR_X3 mode as an example, this section illustrates the collaborative configuration required by the image sensor, CSI receiver, and ISP. The image sensor is configured with HDR_X2 mode enabled, outputting three exposures: long (L), medium (M), and short (S). It outputs L frames through virtual channel (VC0), M frames through VC1, and S frames through VC2. VCs are fixedly mapped to the exposure frames to avoid confusion. The row interleaving order of the raw image data (RAW) is L0→M0→S0→L1→M1→S1. Therefore, the CSI receiver needs to enable VC0 / 1 / 2, with the mapping between VCs and exposure frames consistent with the image sensor. The ISP also needs to enable VC0 / 1 / 2, with the mapping between VCs and exposure frames consistent with both the image sensor and CSI receiver. Deinterleaving is performed according to the row interleaving order of the image sensor to restore the three independent RAW frames. During image synthesis, the images are fused using L / M / S weights.

[0040] In related technologies, V4L2-based image processing systems often perform independent HDR configurations for hardware modules such as image sensors, CSI receivers, and ISPs, failing to consider the entire image pipeline as a whole and resulting in significant systemic coordination deficiencies. For example, due to the lack of an atomic synchronization configuration mechanism, it is highly susceptible to configuration lag or mismatch in certain hardware modules, leading to parameter mismatch in the entire image processing pipeline and causing image distortion, color anomalies, or data processing failures.

[0041] The atomic synchronous configuration mechanism means that for multiple hardware modules, either all hardware modules' configuration changes succeed and take effect, or no hardware module is modified and it rolls back to its original state, without any intermediate state where configuration changes for some hardware modules take effect. Furthermore, the lack of security verification for HDR mode configuration changes may lead to instability in the image processing system.

[0042] This application provides an HDR configuration method that can be applied to any processing system comprising multiple hardware modules. The processing system can be, for example, a camera system, image processing system, or digital imaging system used in fields such as smartphones, tablets, automotive electronics, security monitoring, and industrial vision. For example, see... Figure 1 , Figure 1 This is an implementation environment diagram of an HDR configuration method provided in an embodiment of this application. The implementation environment includes a processing system, which includes multiple hardware modules.

[0043] This system requires multiple hardware modules to work together to enable HDR functionality. Therefore, the HDR configuration of these modules needs to be synchronized to ensure stable operation of the entire system. This application does not limit the number of hardware modules. Figure 1 The example uses N hardware modules, where N is a positive integer greater than 1. In one possible scenario, multiple hardware modules are derived from the breakdown of a complex hardware module with the same function, with each module implementing one of those functions. Alternatively, multiple hardware modules may correspond to different processing modules on the same processing pipeline, with each subsequent module processing the output of the preceding module.

[0044] See Figure 2 , Figure 2 This is a flowchart illustrating an HDR configuration method provided in an embodiment of this application. The method can be executed by a processing system comprising multiple hardware modules or a functional module on the processing system. For example, the method is applied to... Figure 1 The implementation environment shown. For example... Figure 2 As shown, the HDR configuration method includes, but is not limited to, the following steps 201-203.

[0045] Step 201: Obtain the HDR configuration request.

[0046] The HDR configuration request is used to configure HDR functionality for multiple hardware modules. For example, these multiple hardware modules are multiple sub-devices in an image processing pipeline, including but not limited to image sensors, CSI receivers, and ISPs. For instance, the HDR configuration request is used to change the HDR mode of multiple hardware modules to a target mode, which includes, but is not limited to, the aforementioned HDR_X2 mode, HDR_X3 mode, or NO_HDR mode.

[0047] The embodiments of this application obtain HDR configuration requests in ways including but not limited to the following two: Method 1, responding to receiving an HDR configuration request from the application layer; Method 2, generating an HDR configuration request in response to the fact that the currently configured HDR modes of multiple hardware modules differ from the adaptive mode, where the target mode is the adaptive mode. The adaptive mode is an operating mode adapted to at least one of the environmental parameters or power consumption parameters of the multiple hardware modules.

[0048] In this embodiment, the adaptive mode is determined based on at least one of the environmental parameters or power consumption parameters of multiple hardware modules. The environmental parameters indicate the operating environment of the multiple hardware modules and include one or more of the following: average scene brightness, contrast ratio, or motion detection flags. The power consumption parameters indicate the operating power consumption of the multiple hardware modules and include one or more of the following: power supply level, chip temperature, or user-set performance mode. The average scene brightness refers to the average brightness of the surrounding environment of the processing system where the multiple hardware modules are located; in an image processing system, it refers to the ambient brightness of the acquired image. The contrast ratio also refers to the average contrast of the surrounding environment of the processing system where the multiple hardware modules are located. The motion detection flags refer to the motion state of the processing system where the multiple hardware modules are located.

[0049] For example, if the adaptive mode is determined based on environmental parameters of multiple hardware modules, then when the average scene brightness is below a brightness threshold, the adaptive mode is a high dynamic range (HDR) mode that uses two exposure frames to synthesize an image, such as HDR_X2 mode; or, when the contrast ratio is above a contrast threshold, the adaptive mode is an HDR mode that uses three exposure frames to synthesize an image, such as HDR_X3 mode; or, when the motion detection metric indicates that the motion rate is greater than a rate threshold, the adaptive mode is an image mode that uses a single exposure frame, such as NO_HDR mode. Under other environmental parameters, it can be considered that there is no adaptive mode. The brightness threshold, contrast threshold, and rate threshold can all be flexibly set.

[0050] If the adaptive mode is determined based on the power consumption parameters of multiple hardware modules, then when the battery level is below a threshold, the adaptive mode uses a single-exposure frame image mode, such as NO_HDR mode; or when the chip temperature is above a threshold, the adaptive mode uses a high dynamic range (HDR) mode that synthesizes an image using two exposure frames, such as HDR_X2 mode; or, when the performance mode is power-saving mode, the adaptive mode uses a single-exposure frame image mode, such as NO_HDR mode. Both the battery level threshold and the stability threshold can be flexibly set.

[0051] Under other environmental parameters, or under other power consumption parameters, it can be assumed that no adaptive mode exists. In this case, the system can operate according to the currently configured HDR mode or the reference mode issued by the application layer. If the adaptive mode is determined based on the environmental and power consumption parameters of multiple hardware modules, then a first adaptive mode can be determined based on the environmental parameters of the multiple hardware modules, and a second adaptive mode can be determined based on the power consumption parameters of the multiple hardware modules. One of the first and second adaptive modes is then selected as the final adaptive mode. For example, the adaptive mode that is closest to the reference mode among the first and second adaptive modes can be selected; or, the adaptive mode with lower complexity among the first and second adaptive modes can be selected.

[0052] Step 202: Determine HDR configuration parameters based on the HDR configuration request.

[0053] In this scenario, multiple hardware modules require different parameters for the same operating mode. For example, these hardware modules include an image sensor, a CSI receiver, and an ISP. When simultaneously configuring the same HDR mode for the image sensor, CSI receiver, and ISP, the image sensor needs to be configured with parameters such as the number of exposure groups, VC mapping, and line interleaving order; the CSI receiver needs to be configured with parameters such as the number of exposure groups and VC mapping; and the ISP needs to be configured with parameters such as the number of exposure groups, VC mapping, line interleaving order, and composition weights. Therefore, determining the HDR configuration parameters based on the HDR configuration request includes: determining the HDR configuration parameters corresponding to each of the multiple hardware modules based on the HDR mode indicated by the HDR configuration request.

[0054] In one possible implementation, before determining the HDR configuration parameters based on the HDR configuration request, it is first determined whether multiple hardware modules are operating according to the parameters of the currently configured operating mode. Then, if multiple hardware modules are not operating according to the parameters of the currently configured operating mode, i.e., if multiple hardware modules are not in an operating state, the HDR configuration parameters are determined based on the HDR configuration request. This application does not limit the method of sensing the operating state of multiple hardware modules; it can sense only the operating state of any one of the multiple hardware modules. If any one hardware module is in an operating state, then it is considered that multiple hardware modules are in an operating state.

[0055] Optionally, if multiple hardware modules are running according to the parameters of the currently configured operating mode, i.e., multiple hardware modules are in operation, the HDR configuration request is rejected and the HDR configuration parameters are not determined. Alternatively, the HDR configuration parameters are determined based on the HDR configuration request after the multiple hardware modules stop running.

[0056] For example, taking multiple hardware modules including an image sensor as an example, before determining the HDR configuration parameters, the method further includes: determining the streaming media status of the image sensor; determining the HDR configuration parameters includes: if it is confirmed that the image sensor is in a non-streaming media status, that is, the image sensor is not operating according to the parameters of the currently configured operating mode, then determining the HDR configuration parameters. After determining the streaming media status of the image sensor, the method further includes: if it is confirmed that the image sensor processing is in an active video stream output state, that is, the image sensor is operating according to the parameters of the currently configured operating mode, then rejecting the HDR configuration request.

[0057] In one possible implementation, if the HDR configuration request is generated based on adaptive mode, the HDR configuration parameters can be determined directly according to the adaptive mode. If the HDR configuration request is issued by the application layer, the HDR configuration parameters can be determined directly according to the target mode indicated by the HDR configuration request; alternatively, it can be determined whether the target mode matches the adaptive mode. If they match, the HDR configuration parameters corresponding to the target mode are determined; if they do not match, the HDR configuration parameters are determined according to the adaptive mode.

[0058] In this context, "target mode matching" means that the target mode does not conflict with at least one of the environmental or power consumption parameters of multiple hardware modules; for example, the complexity of the target mode is equal to or lower than the complexity of the adaptive mode. "Target mode mismatch" means that the target mode conflicts with at least one of the environmental or power consumption parameters of multiple hardware modules; for example, the complexity of the target mode is higher than the complexity of the adaptive mode. For instance, the complexity of HDR_X3 mode is higher than that of HDR_X2 mode, and the complexity of HDR_X2 mode is higher than that of NO_HDR mode.

[0059] When determining HDR configuration parameters according to adaptive mode, the determination of HDR configuration parameters includes: obtaining environmental parameters and determining HDR configuration parameters based on the environmental parameters; or obtaining power consumption parameters and determining HDR configuration parameters based on the power consumption parameters; or obtaining both environmental parameters and power consumption parameters and determining HDR configuration parameters based on both environmental parameters and power consumption parameters.

[0060] Corresponding to the above-mentioned method of obtaining adaptive mode, the method of determining HDR configuration parameters based on environmental parameters includes: when the average scene brightness is lower than the brightness threshold, determining HDR configuration parameters based on the HDR mode of synthesizing an image using two exposure frames; or, when the contrast ratio is higher than the contrast threshold, determining HDR configuration parameters based on the HDR mode of synthesizing an image using three exposure frames; or, when the motion detection flag indicates that the motion rate is greater than the rate threshold, determining HDR configuration parameters based on the image mode using a single exposure frame.

[0061] The methods for determining HDR configuration parameters based on power consumption parameters include: determining HDR configuration parameters based on an image mode using a single exposure frame when the power supply is below a power threshold; or determining HDR configuration parameters based on an HDR mode using an image synthesized from two exposure frames when the chip temperature is above a temperature threshold; or determining HDR configuration parameters based on an image mode using a single exposure frame when the performance mode is power saving mode.

[0062] Step 203: Send HDR configuration parameters to multiple hardware modules according to a preset timing sequence. The HDR configuration parameters are used by multiple hardware modules to configure HDR.

[0063] In this embodiment, the preset timing sequence can be determined based on the pipeline order of multiple hardware modules. For example, if the preset timing sequence is image sensor, CSI receiver, and ISP, then the process of sending HDR configuration parameters to multiple hardware modules according to the preset timing sequence includes: first sending HDR configuration parameters to the image sensor to ensure that the image sensor outputs the configured data format; after the image sensor is successfully configured, then sending HDR configuration parameters to the CSI receiver and ISP in sequence to prepare the CSI receiver and ISP to receive and process the data output according to the configured data format.

[0064] By sending HDR configuration parameters to multiple hardware modules according to a preset timing sequence, the system ensures that the modules can be configured sequentially, guaranteeing configuration consistency across all modules. If any hardware module fails to configure during the process of sending HDR configuration parameters according to the preset timing sequence, the configured hardware module is reverted to its previous state.

[0065] In one possible implementation, before sending HDR configuration parameters to multiple hardware modules according to a preset timing sequence, a security check is performed on the multiple hardware modules. This security check verifies whether the multiple hardware modules support the configuration of the HDR configuration parameters. The security check includes one or more of the following: querying the configuration data of the hardware modules to confirm whether they support configuring the HDR configuration parameters; querying whether the system resources, memory bandwidth, or system processing power of the hardware modules are sufficient to confirm whether the requirement to configure the HDR configuration parameters is supported; and assessing whether, under the current system load, configuring the HDR configuration parameters on the multiple hardware modules can meet performance requirements.

[0066] Optionally, the security check includes three layers: hardware compatibility check, resource availability check, and performance constraint check. Taking multiple hardware modules, including an image sensor, CSI receiver, and ISP, as an example, the hardware compatibility check is used to consult the image sensor's datasheet or driver capability table to confirm whether the image sensor supports HDR configuration parameters; the resource availability check is used to check whether system resources such as digital signal processors, memory bandwidth, etc., are sufficient to meet the high throughput processing requirements under HDR configuration parameters; the performance constraint check is used to evaluate whether, under the current processing system load, the application of this HDR configuration parameter can meet the performance requirements such as frame rate.

[0067] For example, taking multiple hardware modules including an image sensor, a CSI receiver, and an ISP as an example, see [link to relevant documentation]. Figure 3The diagram shows the state transitions during the configuration verification and application process. Initially, the image sensor, CSI receiver, and ISP are in a stable state under their current operating modes. Upon receiving a mode change request (corresponding to an HDR configuration request), the request indicates the target HDR mode. Configuration verification is first performed through a triple security check, and the configuration is applied through a synchronization mechanism only after all verifications are passed.

[0068] like Figure 3 As shown, a hardware compatibility check determines whether the target HDR mode is supported (i.e., whether the HDR configuration parameters corresponding to the target HDR mode are supported). If not, the verification fails, and the system remains in its current stable state. If supported, a resource availability check determines whether resources are sufficient. If resources are insufficient, the verification fails, and the system remains in its current stable state. If resources are sufficient, a performance constraint check determines whether the performance meets the performance requirements. If the performance does not meet the requirements, the verification fails, and the system remains in its current stable state. If the performance meets the requirements, all verifications pass, and the system is configured and applied.

[0069] Continue as Figure 3 As shown, during the application configuration process, the image sensor is configured first. Specifically, the image sensor is configured for HDR according to the parameters of the target HDR mode. If the image sensor configuration fails, a configuration error is identified, and the system remains in its current stable state. If the image sensor configuration is successful, the CSI receiver is configured. The CSI receiver is configured for HDR according to the parameters of the target HDR mode. If the CSI receiver configuration fails, a configuration error is identified, and the system remains in its current stable state. If the CSI receiver configuration is successful, the ISP is configured. The ISP is configured for HDR according to the parameters of the target HDR mode. If the ISP configuration fails, a configuration error is identified, and the system remains in its current stable state. If the ISP configuration is successful, all modules are confirmed to be configured successfully, ensuring that the image sensor, CSI receiver, and ISP are all updated to the stable state of the target mode.

[0070] In summary, this method synchronizes the parameters of the target mode across multiple hardware modules after the target mode passes the security check. Furthermore, it only runs according to the modified target mode parameters after all multiple hardware modules have been successfully configured. This ensures consistency in operating modes across multiple hardware modules, preventing errors in the processing pipelines corresponding to those modules, while also guaranteeing operational security after configuration changes and improving the operational stability of the multiple hardware modules.

[0071] The following example illustrates an application using the method described in this embodiment to implement HDR configuration, taking multiple hardware modules including an image sensor, a CSI receiver, and an ISP. For example, in this application scenario, the method can be implemented by... Figure 4The multi-hardware module configuration system shown is a centralized, intelligent configuration management framework. For example... Figure 4 As shown, the multi-hardware module configuration system includes an application layer, a configuration manager, and a multi-module configurator, with the method executed by the configuration manager. The application layer includes application programs, and the configuration manager includes a status monitoring module, a scene analysis module, a power management module, a configuration verification module, and a synchronization control module. The multi-module configurator includes an image sensor driver, a CSI receiver driver, and an ISP driver.

[0072] For example, Figure 4 The configuration process of the multi-hardware module configuration system shown can be as follows: Figure 5 As shown. In step S1, the application layer initiates an HDR configuration request. Optionally, the application layer initiates the HDR configuration request through the Input / OutputControl (ioctl) interface. ioctl is the core interface for transmitting control commands between user space and the kernel / driver, used to handle HDR configuration, status queries, or special operations for sub-devices. The ioctl interface adopts a "single interface + multiple commands" design; a single ioctl system call uses different command codes to distinguish different control operations, supports the transmission of complex data structures, and can carry multi-parameter configurations.

[0073] In step S2, the configuration manager checks the streaming media status through the status monitoring module. If it is running, i.e., transmitting a video stream, the process terminates and returns a "busy" signal to the application layer; otherwise, proceed to step S3.

[0074] Step 2 provides a state-aware, delayed configuration mechanism. In this mechanism, when the application layer initiates an HDR configuration request via a V4L2 ioctl system call, the configuration manager does not immediately command the hardware to execute the request. Instead, it first queries the state monitoring module, which maintains flags indicating the current streaming media status of the system. These flags include streaming and non-streaming states. A streaming state indicates that a video stream is being transmitted; a non-streaming state indicates that a video stream is not being transmitted, for example, the image sensor preview has not started or has stopped.

[0075] If the streaming status is "streaming," the configuration manager will immediately return a "busy" signal, such as the EBUSY status code, to the application layer to reject the HDR configuration request. All configuration parameters will be temporarily stored to avoid video stream interruption or frame loss due to hardware reconfiguration. The configuration process will continue if the streaming status is not "streaming."

[0076] Therefore, in this state-aware delayed configuration mechanism, a "request-check-delayed execution" mode is adopted. Based on the working status of the image sensor monitored in real time, the configuration timing is intelligently selected, and the reception of the configuration request and the execution of the hardware parameters are separated in time. This avoids the problem of video stream interruption caused by dynamically configuring HDR parameters during video stream operation. In other words, it fundamentally solves the timing conflict between dynamic configuration and real-time streaming media, so that the mode change process will not cause screen stuttering, frame skipping or application errors, and can realize advanced functions such as "seamless" zoom or dynamic image quality adjustment.

[0077] After the streaming media status is checked, the HDR configuration request is not executed directly, but is instead sent to an intelligent decision-making layer for optimization. This intelligent decision-making layer includes two core modules: a scene analysis module and a power management module.

[0078] In step S3, the configuration manager performs environmental analysis based on real-time environmental parameters through the scene analysis module, and recommends an optimized HDR mode based on the environmental analysis results.

[0079] The scene analysis module, as a software logic unit, continuously acquires real-time environmental parameters from the ISP or a dedicated image sensor. These parameters include brightness, contrast, and motion signs. Optionally, brightness refers to the average brightness of the scene. The pre-built strategy engine within the scene analysis module performs environmental analysis based on these real-time parameters and recommends optimized HDR modes.

[0080] For example, see Figure 6 The diagram shows the logic of the adaptive configuration decision. The scene analysis module's inputs include average scene brightness, contrast ratio, and motion indicators. If the average scene brightness is below the brightness threshold, indicating a low-light scene, the scene analysis module prioritizes recommending HDR_X2 mode to enhance shadow details. If the contrast ratio is above the contrast threshold, indicating a high-contrast scene, the scene analysis module recommends HDR_X3 mode to maximize dynamic range. If fast motion is detected, to avoid artifacts (ghosting) and reduce processing latency, the scene analysis module recommends NO_HDR mode. When the brightness is above the brightness threshold, the contrast ratio is below the contrast threshold, or no fast motion is detected (i.e., other cases), the scene analysis module does not recommend HDR mode.

[0081] Step S4: The configuration manager optimizes the system status through the power management module, that is, it performs secondary optimization on the HDR mode recommended by the scene analysis module based on the system power consumption message.

[0082] System power consumption information includes, but is not limited to, battery level, chip temperature, and performance mode. The power management module interacts with the underlying power management service to obtain information such as battery level and chip temperature, and is aware of the user-set performance mode. Based on the system power consumption parameters, the power management module performs secondary optimization on the HDR mode recommended by the scene analysis module.

[0083] For example, see Figure 6 The diagram shows the logic of the adaptive configuration decision. The power management module's inputs include battery level, chip temperature, and performance mode. When the battery level is below 20% or the system is in forced power-saving mode, the power management module will reject the suggestion to enable HDR mode, forcing the system to use the basic NO_HDR mode to save power. When the chip temperature is too high, for example, above 70 degrees Celsius, the power management module suggests downgrading the HDR mode, for example, from the high-load HDR_X3 mode to the lower-load HDR_X2 mode to prevent overheating. When the performance mode is in power-saving mode, the system is forced to use the basic NO_HDR mode to save power. When the battery level is above 20%, the chip temperature is below 70 degrees Celsius, and the performance mode is not in power-saving mode (i.e., other situations), the power management module does not recommend HDR mode, meaning it does not perform secondary optimization on the HDR mode recommended by the scene analysis module.

[0084] Therefore, the scene analysis module and power management module can intelligently optimize the HDR mode. For example, based on the actual shooting scene (such as low light, backlight, motion) and device status (such as battery level, temperature), intelligent and adaptive configuration recommendations and optimizations can be made to maintain the best balance between image quality, system performance and power consumption in complex real-world usage scenarios.

[0085] For each HDR mode specified in the HDR configuration request, recommended by the scene analysis module, and recommended by the power management module, the HDR mode with the lowest complexity is selected as the final target HDR mode. For example, if the HDR configuration request specifies HDR_X3 mode and the scene analysis module or power management module recommends NO_HDR mode, the target HDR mode is determined to be NO_HDR mode; if the HDR configuration request specifies HDR_X2 mode, the scene analysis module recommends HDR_X3 mode, and the power management module does not recommend an HDR mode, the target HDR mode is determined to be HDR_X2 mode. Alternatively, the HDR mode recommended by the power management module after secondary optimization is selected as the final target HDR mode.

[0086] After the target HDR mode is obtained by the intelligent decision-making layer, it is not applied immediately. Instead, it enters a critical security check layer to perform a series of proactive checks. The security check layer includes a configuration verification module.

[0087] In step S5, the configuration manager performs a triple security check on the finally determined target HDR mode through the configuration verification module. If the verification is successful, proceed to step S6; if the verification fails, proceed to step S7.

[0088] The triple security check includes hardware compatibility checks, resource availability checks, and performance constraint checks. Hardware compatibility checks involve consulting the image sensor's datasheet or driver capability table to confirm whether the image sensor supports the target HDR mode. Resource availability checks ensure that system resources such as the digital signal processor, memory bandwidth, etc., are sufficient to meet the high throughput processing requirements of the target HDR mode. Performance constraint checks assess whether, under the current system load, applying this target HDR mode can meet performance requirements such as frame rate.

[0089] The target HDR mode will only be applied after all three security checks pass. If any security check fails, the configuration process will abort and return an error code to the application layer, indicating the specific reason for the error.

[0090] Step S6: The configuration manager performs multi-hardware module configuration synchronization through the synchronization control module, that is, atomically synchronizes the parameters of the target HDR mode to the image sensor, CSI and ISP according to a predetermined sequence; if synchronization fails, for example, an error occurs during the synchronization process, proceed to step S7; if all hardware modules are successfully synchronized, proceed to step S8.

[0091] Once the target HDR configuration passes the triple security check, the synchronization control module begins operation. Internally, the synchronization control module maintains a configuration synchronization manager, which holds references to drivers for multiple V4L2 sub-devices, including the image sensor, CSI receiver, and ISP. Following a predetermined sequence, the synchronization control module sends the same HDR mode configuration parameters to all V4L2 sub-devices.

[0092] The predetermined sequence can be a pre-defined, optimal timing sequence. For example, a typical predetermined sequence is to first configure the image sensor to ensure it outputs the correct data format, and then sequentially configure the CSI receiver and ISP to prepare them for receiving and processing the data output by the image sensor. This atomic, synchronous operation ensures that the entire pipeline from acquisition to processing has a consistent understanding of the HDR mode at any given moment, avoiding problems such as image distortion, color distortion, or processing failure caused by asynchronous configuration of individual modules.

[0093] For example, see Figure 7The diagram shows the sequence of multi-module configuration synchronization. After the application layer sends an HDR configuration request to the configuration manager, the configuration manager performs stream state checks, adaptive recommendations, and security verification. First, it configures the target HDR mode parameters for the image sensor driver in the multi-module configurator, i.e., sends HDR configuration parameters to the image sensor driver. If the image sensor driver configuration fails, the configuration manager's summary synchronization result is considered a failure, triggering a rollback mechanism and returning an error to the application layer. If the image sensor driver configuration succeeds, it then configures the target HDR mode parameters for the CSI receiver driver in the multi-module configurator, i.e., sends HDR configuration parameters to the CSI receiver driver.

[0094] If the CSI receiver driver configuration fails, the synchronization result obtained by the configuration manager will be considered a failure, triggering a rollback mechanism and returning an error to the application layer. If the CSI receiver driver configuration succeeds, the parameters for the target HDR mode will be configured for the ISP driver in the multi-module configurator, i.e., HDR configuration parameters will be sent to the ISP driver. If the ISP driver configuration fails, the synchronization result obtained by the configuration manager will be considered a failure, triggering a rollback mechanism and returning an error to the application layer. If the ISP driver configuration succeeds, the synchronization result obtained by the configuration manager will be considered a success, and a success message will be returned to the application layer.

[0095] Step S7: Trigger the rollback mechanism to restore all hardware modules to their previous configuration and report errors to the application layer, for example, by returning error codes to the application layer.

[0096] To address the rare occurrence of unexpected failures during application configuration, this application incorporates a rollback mechanism. This mechanism securely saves the HDR configuration parameters from the previous stable state. If the synchronization configuration of the target HDR mode fails, it automatically and quickly restores all relevant hardware modules to their previous stable state and records error logs, thereby significantly enhancing the system's fault tolerance and reliability.

[0097] Step S8: Return a success message to the application layer, completing the configuration change.

[0098] Therefore, by configuring the system with multiple hardware modules, it is possible to ensure that the HDR modes of multiple independent hardware modules such as image sensors, CSI receivers, and ISPs in the image processing pipeline are atomically consistent, avoiding image anomalies caused by configuration asynchrony. Furthermore, by integrating scene analysis and power management modules, the HDR mode can dynamically adjust according to ambient light, motion, system power consumption, and temperature, achieving an intelligent balance between image quality, system performance, and power consumption. This automatically provides users with the optimal image effect while intelligently reducing power consumption in scenarios with low power. In addition, a security and reliability guarantee mechanism is configured. By introducing a complete configuration security chain including pre-verification, failure rollback, and emergency recovery, multiple feasibility checks are performed before configuration changes, and the system can automatically recover to a stable state in the event of failure, greatly improving the system's robustness.
