Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant disclosure and are not limiting of the disclosure. It should be further noted that, for the convenience of description, only the portions relevant to the disclosure are shown in the drawings.

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

It can be understood that as the photographing effect of the camera configured on the electronic device is more and more emphasized by the user, the good photographing effect under various environments is also gradually becoming a key.

Compared with a double-LED lamp or a single-LED lamp, the double-color-temperature flash lamp is softer in imaging effect and more accurate in white balance. The double-color-temperature lamp is used for photographing in a dark light environment, the quality of the picture can be obviously improved, and therefore more and more electronic equipment starts to adopt the technology of the double-color-temperature flash lamp.

It can also be understood that before the electronic device using the dual-color-temperature flash lamp is put into the market, the calibration process of the dual-color-temperature flash lamp is required to be executed, the flash lamp calibration data of different color temperature proportional values is generated, namely, the calibration result file is obtained, and then the generated calibration result file is utilized in the flashing process, so that the flashing photographing effect is improved.

Generally, to improve the calibration accuracy of a dual-color temperature flash, calibration of the flash may generate calibration data under a specific light box, e.g., the corresponding flash calibration operation is typically done with an in-line customized light box.

In some related technologies, Calibration of a Dual-color flash, such as Calibration of a Dual-color flash on a high-pass CAMX architecture, is to set a Calibration command, such as a Dual LED Calibration, in a camxoverriesettings.txt file, so that a flash Calibration process of an electronic device will be run each time any camera application is turned on after setting. And after the calibration is successful, a flash lamp calibration result file can be generated in the electronic equipment.

In the related art, since the command of the dual LED Calibration Mode is set, when all camera applications on the electronic device are turned on, a Calibration flow of the two-color temperature flash lamp is run, so that the flash lamp continuously flashes during the Calibration process, and the photographing effect of the camera applications is affected.

In addition, since the calibration data needs to be generated under a specific lamp box for flash lamp calibration, so as to improve the accuracy, that is, the calibration operation of the flash lamp is usually performed by utilizing a production line customized lamp box, in the related art, after the calibration command is set, the flash lamp calibration process is executed each time the camera application is opened, so that the data successfully calibrated by utilizing the lamp box may be covered under some scenes with similar color temperatures, and further the photographing effect of the flash lamp may be affected.

Moreover, in the related art, after the flash lamp calibration process is completed, whether a calibration result file is generated can only be checked through an ADB command, and then the calibration result is determined, so that the efficiency is low, and the flash lamp calibration process is not suitable for being used in a wide production line.

In the implementation of the present application, in order to solve the problems that in the calibration process, each camera application runs a calibration program after being opened, a flash lamp continuously flashes, and an original file is covered after the calibration is finished, so that the calibration result is poor, by developing an application designed for dual color temperature flash calibration, the electronic device of the client on which the application is installed, when the flash lamp calibration is carried out, a tester can carry out human-computer interaction with a client interface of the electronic equipment, so that the client responds to an input instruction of the tester, after the electronic equipment is judged not to successfully execute the calibration program, a calibration instruction is issued to a Hardware Abstraction Layer (HAL) of the electronic equipment to start a flash lamp calibration program, and then improve calibration efficiency and degree of accuracy, avoid the repeated execution of flash lamp calibration flow to ensure the normal operating of other camera applications.

It can be understood that the electronic device in the embodiment of the present application may be a device such as a smart phone and a tablet computer, which is equipped with various camera applications and can implement a photographing function.

It can be understood that, in order to implement the method of the embodiment of the present application, a corresponding operating system may be run on the electronic device.

For example, as shown in fig. 1, a schematic view of an Android operating system running on an electronic device according to an embodiment of the present application is shown, and as shown in fig. 1, the architecture of the operating system is sequentially divided into a bottom layer part, a core part, and an application part from bottom to top. The bottom layer part comprises a kernel and a HAL layer; the core part comprises a system core class library, an Android runtime environment, a framework layer and the like; the application part includes an application layer. Each of which includes a corresponding sub-module or subsystem.

The hardware abstraction layer is an interface layer located between an operating system, an electronic device kernel and a hardware circuit, provides a virtual hardware platform for the operating system, and may include a camera HAL layer and the like.

The application layer runs on an operating system and comprises a plurality of application programs, such as the application program for flash calibration in the embodiment of the application, so as to calibrate the flash of the camera on the bottom layer.

It is to be understood that the above operating system architecture on the electronic device is only an exemplary illustration, and the embodiment of the present application is not limited thereto, as long as the camera calibration client capable of implementing the application layer implements data interaction with the HAL layer to complete the flash calibration procedure.

It will be appreciated that in actual use, as shown in FIG. 2, the tester operates on the client interface of the application to input instructions. After receiving the instruction input by the tester, the client may respond to the input instruction to perform data interaction with the camera HAL layer of the operating system, so as to complete the flash calibration process.

In order to better understand the calibration method of the bicolor warm flash lamp provided by the embodiment of the application, the following detailed description is provided by fig. 3 to fig. 9.

Fig. 3 is a flash lamp calibration method according to an embodiment of the present application, where the method is applicable to the electronic device described in fig. 1, and a client for flash lamp calibration is installed on the electronic device, where the method includes the following steps:

s110, the client receives an input instruction.

And S120, the client responds to the input instruction and reads the indication identifier of the calibration result file.

And S130, when the indication mark indicates that the calibration result file does not exist, the client issues the calibration instruction to the camera hardware abstraction layer, so that the camera hardware abstraction layer responds to the calibration instruction to execute the flash lamp calibration program.

Specifically, in the embodiment of the application, when a tester performs calibration of a dual-color temperature flash lamp of an electronic device, a calibration program can be started by operating a client installed on the electronic device and used for flash lamp calibration.

As shown in fig. 4, a tester may click on an icon of a flash lamp calibrated client to input a touch instruction to the electronic device.

Or, in some embodiments, the tester clicks an icon of the flash lamp calibration client, and after the client is opened, a button for starting calibration is presented on the operation interface of the client, so that the tester starts the calibration program by operating the button.

For example, the calibration procedure may be initiated by a touch operation, such as clicking a button, or by voice input.

After receiving an instruction input by a tester on an operation interface, a client on the electronic device responds to the input instruction, reads an indication identifier of a calibration result file from the kernel, for example, transmits a file identification instruction to the kernel of the electronic device to obtain the indication identifier of the flash lamp calibration result file, and then identifies whether the flash lamp calibration result file is currently stored in the kernel of the electronic device by using the obtained indication identifier, namely, judges whether the flash lamp calibration process is currently executed by the electronic device.

Further, when the indication flag of the calibration result file returned by the kernel of the electronic device indicates that no calibration result file exists currently, that is, the electronic device has not executed or has not successfully executed the flash lamp calibration program. The client may issue a calibration instruction to a camera HAL layer in an operating system on the electronic device in response to the acquired indication identifier, so that the flash calibration procedure is started to be executed in response to the calibration instruction at the camera HAL layer.

For example, after a tester clicks an icon of a flash calibration client on an operation interface shown in fig. 4 to input an instruction, the electronic device responds to the input instruction, reads a current calibration result file indication identifier in a kernel of the electronic device, and when the indication identifier indicates that the flash calibration result file is not stored in a memory space of the electronic device, the flash calibration client issues a customized and dedicated OP _ MODE value to the camera HAL layer to control to start a flash calibration process.

According to the flash lamp calibration method in the embodiment of the application, the client for flash lamp calibration which is developed and designed is installed on the electronic equipment, so that a tester can input a flash lamp calibration instruction to the client through an operation interface, the client responds to the calibration result file indication mark obtained by the input instruction, and when the indication mark indicates that the electronic equipment does not execute flash lamp calibration, the electronic equipment starts to execute the calibration program, thereby avoiding the flash lamp calibration program from being continuously and repeatedly executed, causing the flash lamp to continuously flicker, ensuring the normal operation of other camera applications, covering accurate data calibrated by using the calibration lamp box, improving the accuracy and efficiency of flash lamp calibration, and simplifying the operation.

Optionally, in this embodiment of the application, in order to improve calibration efficiency and simplify operation, the calibration instruction issued by the client to the camera HAL layer may be an OP _ MODE value generated in a pre-customized manner.

It will be appreciated that in other embodiments, the calibration instructions may also be commands generated by the client in real time in response to the file indication identifier.

Further, in some embodiments of the present application, after the flash calibration procedure is completed in the camera HAL layer, if the calibration is successful, a flash calibration result file is generated in the camera HAL layer, and the generated calibration result file is stored in a kernel of the electronic device.

Optionally, in this embodiment of the application, after the client for flash lamp calibration is installed and operated on the electronic device, in order to improve user experience, in an operation process after the client receives an input instruction of a tester, corresponding prompt information may be displayed in real time according to a calibration progress condition of the flash lamp, so as to indicate a calibration result or a calibration state of the current electronic device.

For example, the prompt message may include a first prompt message, a second prompt message, and calibration status information, where the first prompt message may indicate that the flash calibration is successful, the second prompt message indicates that the flash calibration is failed, and the status information indicates that the electronic device is executing a flash calibration procedure.

Or, in other embodiments, when the indication identifier of the read calibration result file indicates that the calibration result file is currently stored in the electronic device in response to the input instruction, file state information indicating that the calibration result file is already stored may also be displayed on the basis of the first information indicating that the calibration is successful being displayed on the interface.

Optionally, in some embodiments, in order to improve user experience, when the prompt information is displayed on the client interface, a prompt box may be set, and then the content of the prompt information is displayed in the prompt box, so that a tester can visually check the content. As shown in fig. 5 to 8.

Specifically, in some embodiments, when the electronic device responds to an input instruction of a tester, and the read indication identifier of the calibration result file indicates that the calibration result file currently exists, the electronic device indicates that the flash calibration program has been successfully executed on the electronic device, and does not need to be started again. The client may respond to the indication identifier of the calibration result file, directly output feedback information indicating that the calibration is successful, that is, first prompt information, and display the first prompt information on the interface of the client, and display file status information to prompt that the flash lamp calibration program is successfully executed.

As shown in fig. 7, a prompt box may be displayed on the interface of the client, the "calibration result" may be displayed in the prompt box, and the file status information of the "flash calibration result file already exists" may be displayed.

Or, in other embodiments, when the camera HAL layer of the electronic device responds to the calibration instruction issued by the client, the flash lamp calibration program is executed, and after the calibration is completed, a value representing the calibration result may be returned to the client, so that the corresponding prompt information of the calibration result may be displayed on the client interface.

For example, after the camera HAL layer completes the flash calibration process, if the calibration is successful, a flash calibration result file is generated, and the result value 1 to metadata of the successful calibration is written back to notify the flash calibration client of the result of this calibration. If the calibration fails, the camera HAL layer does not generate a flash lamp calibration result file, writes back a result value 0 to metadata of the calibration failure, and informs the flash lamp calibration client of the current calibration result.

The flash lamp calibration client displays a prompt box by reading the returned metadata value and imaging, so that first prompt information of successful calibration or second prompt information of failed calibration is displayed in the prompt box to inform a tester of the result of the calibration of the dual-color temperature flash lamp.

As shown in fig. 5 and 6, "calibration successful" is displayed below the word of the calibration result in the display frame: 1 ", or" calibration failed: 0 "is used as the second prompt message.

It can be understood that, in the related art, after the flash lamp calibration process is completed, whether the calibration result file is generated or not can only be checked through the ADB command to determine the calibration result, which results in complex operation and low efficiency.

Further, in some embodiments, in order to improve the user experience and enable the user to master the execution condition of the flash lamp calibration program in real time, the calibration status information may be displayed in the prompt box after the tester inputs the instruction.

For example, as shown in FIG. 8, a word "calibrate, please wait" may be displayed in the prompt box to indicate the progress being performed.

In the flash lamp calibration method in the embodiment of the application, a client for flash lamp calibration which is developed and designed is installed on an electronic device, so that a tester can input a flash lamp calibration instruction to the client through an operation interface, and further, a calibration result file indication mark which is obtained by responding to the input instruction at the client is used for starting to execute a calibration program when the electronic device does not execute flash lamp calibration, and in the calibration process, prompt information in the execution process of the calibration program is displayed in a prompt box of an interface of the client in real time, and then after successful calibration, a calibration result file is generated and stored, so that continuous flash lamp continuous flicker caused by continuous and repeated execution of the flash lamp calibration program is avoided, and accurate data after calibration by using a calibration lamp box is covered, and the accuracy and the efficiency of flash lamp calibration are improved, the user experience is improved.

Further, in order to better understand the implementation process of the flash lamp calibration method in the embodiment of the present application, the following is explained in detail by fig. 9.

As shown in fig. 9, when a tester needs to perform flash calibration on a current electronic device, first, an icon of a flash calibration client may be clicked to input an instruction to the electronic device. The client can respond to the input instruction, whether the current electronic equipment already has the calibration result file of the flash lamp is read, if the calibration result file exists, the current electronic equipment executes the flash lamp calibration, and the flash lamp calibration is successful, a flash lamp calibration success prompt can be directly output, and the success prompt information and the file state information of the calibration result file exist are displayed in a prompt box.

And if the client for flash lamp calibration reads that the current electronic equipment does not have a flash lamp calibration result file, indicating that the current electronic equipment does not execute the flash lamp calibration process or does not successfully execute the flash lamp calibration process. The flash calibration client issues a customized special OP _ MODE value to the camera HAL layer to control the flash calibration process to be started.

Further, after the camera HAL layer completes the flash lamp calibration process, if the calibration is successful, a flash lamp calibration result file and write-back result values 1 to metadata of successful calibration are generated, and the client side of flash lamp calibration is notified of the current calibration result. If the calibration fails, the camera HAL layer does not generate a flash lamp calibration result file, writes back a result value 0 to metadata of the calibration failure, and informs the current calibration result to a client of the flash lamp calibration. The client side of the flash lamp calibration displays a prompt box for successful or failed calibration in a graphical mode by reading the returned metadata value so as to display prompt information and inform an operator of the result of the double-color-temperature flash lamp calibration at this time, and a tester can conveniently and visually check the calibration result.

Flash lamp calibration in the embodiment of the application, through the customer end that is used for the flash lamp calibration of installation development design on electronic equipment, make the tester pass through operation interface, to the input of client realization flash lamp calibration instruction, with effectively start the flash lamp calibration procedure, continuous repeated execution flash lamp calibration procedure has been avoided, the flash lamp that arouses can last the scintillation, and to the cover of the accurate data after utilizing the calibration lamp house calibration, the degree of accuracy and the efficiency of flash lamp calibration have been improved, user experience has been promoted.
