[0023] 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.

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.

[0025] The following is combined with Figures 1 to 10, the control method of the shooting device, the control device of the shooting device, the shooting device, the electronic device and the readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0026] In an embodiment of the present application, a control method for a photographing device is provided, which is applied to a photographing device, wherein the photographing device includes an optical image stabilization controller, an inertia detection device, and a driving device. Figure 1 A schematic diagram of a control method for a photographing device according to an embodiment of the present application is shown. Figure 1 As shown, the control method of the shooting device includes:

[0027] Step 102, determining target bias data in the bias database;

[0028] Among them, the bias database includes historical collected data of the inertial detection device. The inertial detection device includes an inertial gyroscope. During the operation of the shooting device, the inertial detection device can collect the offset parameters of the camera of the shooting device, and the shooting device can correct the offset parameters. The inertial detection device periodically starts the bias calibration algorithm according to the preset strategy, and calibrates the bias data of the inertial detection device when starting the bias calibration algorithm. When the shooting device is in a standby state, the sampling data of the inertial detection device is obtained, and the sampling data is stored in the bias database. The bias data in the bias database can reflect the current bias situation of the inertial detection device. Specifically, the bias data is the offset of the parameters collected by the inertial detection device under the current working conditions, and the bias data is affected by the hardware characteristics and working environment of the inertial detection device. During the operation of the inertial detection device, the parameters collected by the inertial detection device are corrected by the bias data. Therefore, the bias data can reflect the bias situation of the inertial detection device.

[0029] The bias database also includes the operating parameters of the shooting device. There is a corresponding relationship between the operating parameters and the bias data in the bias database. When the shooting device is in operation, the current operating parameters of the shooting device are collected, and the target bias data in the bias database is determined according to the current operating parameters.

[0030] Exemplarily, the bias data in the bias database includes but is not limited to three-axis acceleration data and three-axis gyroscope data, and the operating parameters include but are not limited to temperature data. Among them, the three-axis acceleration data, the three-axis gyroscope data and the temperature data are stored according to a mapping relationship. When the shooting device is in operation, the current temperature data is collected, and the target bias data can be determined according to the temperature data.

[0031] Step 104, obtaining first sampling data of the optical image stabilization controller;

[0032] Among them, the shooting device has an optical image stabikization (OIS) function. The signal collected by the inertial detection device is filtered and transmitted to the optical image stabikization controller. The data received by the optical image stabikization controller is the first sampling data.

[0033] When the shooting device is in operation, first sampling data in the optical image stabilization controller is acquired, and the data is current sampling data collected by the inertial detection device, that is, the first sampling data.

[0034] Step 106, performing offset elimination on the first sampled data using the target offset data;

[0035] Specifically, since the target bias data is determined based on the current operating parameters of the shooting device, the target bias data can be used to eliminate the bias of the currently collected first sampling data. The first sampling data after bias elimination can retain more low-frequency effective signals output by the inertial detection device, thereby enabling the optical image stabilization system to effectively suppress low-frequency jitters.

[0036] It is worth noting that the low-frequency signal is a signal less than 2 Hz.

[0037] Step 108, controlling the operation of the driving device according to the first sampling data after the offset is eliminated.

[0038] The driving device is selected as a motor, and the motor can drive the camera to move according to the first sampling data after the offset is eliminated, thereby eliminating jitter.

[0039] In the embodiment of the present application, when the shooting device is in operation, the target bias data in the bias database is determined according to the working parameters of the shooting device, and the target bias data is the historical acquisition data of the inertial detection device. Through the target bias data, the first sampling data of the optical image stabilization controller is offset eliminated, and the offset in the output data of the inertial detection device can be filtered out. Through the first sampling data after the offset is eliminated, the operation of the driving device can be accurately controlled, and the camera movement can be accurately controlled to eliminate the jitter during the shooting process.

[0040] It is worth mentioning that the shooting devices include mobile phones, cameras, camcorders, etc.

[0041] In the related art, the data output by the gyroscope in the optical image stabilization system of the shooting device contains a large amount of residual bias data, and a high-pass filter is used to eliminate the bias data. However, in the process of eliminating the bias data through the high-pass filter, some effective low-frequency signals will also be filtered out, resulting in the optical image stabilization system being unable to effectively suppress low-frequency jitter.

[0042] The embodiment of the present application establishes a bias database through the historical collected data of the inertial detection device, and determines the target bias data in the bias database according to the current working condition parameters of the shooting device. After acquiring the first sampling data of the optical image stabilization controller, the first sampling data is offset eliminated through the target bias data, thereby eliminating the bias data in the first sampling data output by the inertial detection device to the optical image stabilization controller while avoiding filtering out the effective low-frequency signal in the first sampling data. Therefore, the driving device can be accurately controlled by the first sampling data after the offset is eliminated, and more low-frequency effective signals of the inertial detection device can be retained during the optical image stabilization process, thereby enabling the optical image stabilization system to effectively suppress the low-frequency jitter of the shooting device.

[0043] In some embodiments of the present application, determining target bias data in a bias database includes: acquiring first temperature data of a photographing device; and determining the target bias data according to the first temperature data and the bias database.

[0044] In an embodiment of the present application, the shooting device further includes a temperature acquisition device, which can be integrated in the inertial detection device. The bias data and the temperature data are stored in the bias database, and there is an association relationship between the temperature data and the bias data. During the operation of the shooting device, the temperature acquisition device can acquire the first temperature data of the shooting device, and the target bias data in the bias database can be determined based on the first temperature data and the association relationship stored in the bias database.

[0045] Specifically, the data bias generated by the inertial detection device during data collection is related to the working state of the shooting device. The working state includes the temperature of the shooting device. Therefore, in the process of establishing the bias database, the temperature data is associated with the bias data. During the operation of the shooting device, the first temperature data of the shooting device is collected by the temperature collection device, and the target bias data can be accurately found based on the first temperature data.

[0046] The embodiment of the present application determines the target bias data in the bias database based on the first temperature data collected during the operation of the shooting device, ensures that the found target bias data is consistent with the current temperature of the shooting device, and achieves the effect of accurately finding the target bias data in the bias database.

[0047] In some embodiments of the present application, target bias data is determined according to the first temperature data and the bias database, and the target bias data is determined, including:

[0048] When the first temperature data is stored in the bias database, searching for the corresponding target bias data according to the corresponding relationship;

[0049] When the first temperature data is not stored in the bias database, the temperature range data is searched based on the first temperature data, and the temperature range data is data corresponding to the temperature range of the first temperature data in the bias database; the target bias data is determined based on the temperature data in the temperature range data and the corresponding bias data.

[0050] It is understandable that in order to ensure the accuracy of the bias data in the bias database, in the process of establishing the bias database, the real historical collection data collected by the inertial detection device and the temperature data corresponding to the historical collection data are stored in the bias database.

[0051] In the embodiment of the present application, during the operation of the shooting device, first temperature data of the shooting device is collected, and the collected first temperature data is searched in the bias database.

[0052] When the first temperature data is found in the bias database, the bias data corresponding to the first temperature data in the bias database is used as the target bias data. Since the bias data and temperature data stored in the bias database are both real historical data collected by the inertial detection device, the target bias data found by searching the first temperature data has a higher accuracy.

[0053] In the case where the first temperature data is not found in the bias database, the temperature range data in the bias database can be found based on the first temperature data to ensure that the first temperature data is within the temperature range data. Specifically, the maximum temperature data in the temperature range data is the temperature data in the bias database that is greater than the first temperature data, and the minimum temperature data in the temperature range data is the temperature data in the bias database that is less than the first temperature data.

[0054] Figure 2 A schematic diagram showing a first-order linear regression fitting curve in an embodiment of the present application is shown, Figure 3 Schematic diagram showing a second-order linear regression fitting curve in an embodiment of the present application, Figure 4 A schematic diagram of a multi-order linear regression fitting curve in an embodiment of the present application is shown.

[0055] like Figure 2 , Figure 3 and Figure 4 As shown, the target bias data can be determined according to the obtained temperature range data and the bias data corresponding to the temperature data in the temperature range data. Specifically, the temperature data in the temperature range data and the corresponding bias data can be optionally subjected to a first-order linear regression calculation to obtain the target bias data corresponding to the first temperature data. It is also optional to perform a second-order or multi-order linear regression calculation based on multiple temperature data in the temperature range data and the corresponding multiple bias data to obtain the target bias data corresponding to the first temperature data.

[0056] In some embodiments, the bias data in the bias database includes three-axis gyroscope data and corresponding temperature data, and the bias data and the temperature data are stored in a table format.

[0057] The details are shown in Table 1.

[0058] Table 1

[0059]

[0060] Among them, GX_Offset is the X-axis gyroscope data, GY_Offset is the Y-axis gyroscope data, and GZ_Offset is the Z-axis gyroscope data.

[0061] It is worth noting that the table can also store three-axis acceleration data, which is also stored in a corresponding relationship with the temperature data, so that the corresponding three-axis acceleration data and three-axis gyroscope data can be found through the temperature data. Among them, due to the influence of production process tolerance, the temperature change characteristics of the three-axis acceleration data of different inertial detection devices are different.

[0062] By storing the temperature data and the bias data according to the association relationship between the two, it is convenient to search for the target bias data in the bias database according to the first temperature data.

[0063] In the embodiment of the present application, when the first temperature data is obtained, the first temperature data is searched in the bias database. When the bias data corresponding to the first temperature data is found, the bias data is used as the target bias data. When the first temperature data is not found, the target bias data is calculated by the temperature range data corresponding to the first temperature data and the corresponding bias data. The target bias data is made to correspond to the first temperature data collected during the operation of the shooting device, thereby improving the accuracy of the determined target temperature data.

[0064] In some embodiments of the present application, the photographing device further includes an inertia detection controller, and the inertia detection controller is connected to the inertia detection device.

[0065] Before determining the target bias data in the bias database, the method also includes: obtaining second sampling data of the inertial detection controller; obtaining second temperature data of the shooting device when the current posture of the shooting device is in a preset posture; and establishing a bias database according to the second temperature data and second sampling data corresponding to the second temperature data.

[0066] When the camera is in standby mode, that is, the camera has not started to operate, the inertia detection device continuously sends the second sampling data to the inertia detection controller. The inertia detection device is connected to the inertia detection controller, and the second sampling data is the sampling data transmitted from the inertia detection device to the inertia detection controller. Before being transmitted to the inertia detection controller, the second sampling data is filtered by the filter.

[0067] It is worth noting that when the shooting device is a portable smart terminal such as a mobile phone, the second sampling data is used to control the operation of the mobile phone. Specifically, when the mobile phone runs other applications, the mobile phone operates according to the second sampling data, for example: running game programs, running map programs, etc.

[0068] When the shooting device is in motion, that is, when the user carries the shooting device, the inertial detection device can continuously collect the second sampling data and transmit the second sampling data to the inertial detection controller. Since the shooting device is in motion at this time, the collected second sampling data is associated with the operating state of the shooting device.

[0069] In the embodiment of the present application, before storing the collected second sampling data in the bias database, it is necessary to determine whether the current posture of the camera device is in a preset posture, wherein the preset posture is that the camera device is in a stationary state. When the camera device is in a stationary state, the second sampling data collected by the inertial detection device at this time is the bias data of the inertial detection device. Since the bias data is related to the ambient temperature of the camera device, the second temperature data is collected when it is detected that the camera device is in a stationary state. An association relationship is established between the second temperature data collected when the camera device is in a stationary state and the second sampling data, and the second database and the second sampling data are stored in the bias database according to the association relationship, thereby completing the establishment of the bias database.

[0070] It is worth noting that the temperature change characteristics of the bias data will change with the use of the inertial detection device. When the shooting device is in standby or stopped, the second temperature data and the second sampling data are continuously collected to ensure that the correspondence between the bias data and the temperature in the bias database remains updated, thereby improving the accuracy of bias elimination during the shooting process.

[0071] It is worth noting that the bias database is established when the shooting device is in the standby state, that is, when the shooting device is in the standby state, the inertial detection device continuously collects the second sampling data and transmits it to the inertial detection controller.

[0072] In some possible implementations, the inertial detection device can collect the second sampled data in real time.

[0073] In some other possible implementations, the inertial detection device can collect the second sampled data according to a preset rule, that is, collect the second sampled data at intervals of a preset time length.

[0074] It can be understood that the second sampling data includes the collected three-axis acceleration data and three-axis gyroscope data.

[0075] In an embodiment of the present application, when the shooting device is in a standby state, the inertial detection device continuously collects the second sampling data and transmits it to the inertial detection controller. The inertial detection controller monitors the posture of the shooting device according to the second sampling data. When the posture of the shooting device is a preset posture, the current second sampling data and the corresponding temperature data are recorded, thereby realizing the establishment of a bias database and the continuous updating of the bias database when the shooting device is in a standby state.

[0076] In some embodiments of the present application, when the current posture of the shooting device is in a preset posture, before acquiring the second temperature data of the shooting device, it also includes: determining the current posture of the shooting device according to the second sampling data.

[0077] In the embodiment of the present application, the second sampling data includes but is not limited to three-axis acceleration data of the shooting device and three-axis gyroscope data, so the current posture of the shooting device can be monitored based on the collected second sampling data.

[0078] Specifically, the shooting device is a mobile phone, and the inertia detection device is set in the mobile phone. When the shooting function of the mobile phone is not turned on, the inertia detection device in the mobile phone continuously collects the second sampling data. The mobile phone can determine the current posture of the mobile phone based on the collected second sampling data.

[0079] The embodiment of the present application monitors the current posture of the shooting device based on the second sampling data collected by the inertial detection device, so that the shooting device can not only determine whether the shooting device is in a preset posture based on the second sampling data, but also establish a bias database based on the second sampling data when the shooting device is in the preset posture.

[0080] In some embodiments of the present application, the inertial detection device includes an acceleration detection device and a gyroscope, and the target bias data includes one or a combination of the following: three-axis acceleration data, three-axis gyroscope data.

[0081] In the embodiment of the present application, the inertial detection device includes a deceleration detection device for detecting acceleration data, and a gyroscope for detecting three-axis gyroscope data. It can be understood that the three-axis gyroscope data is the posture data of the camera. That is, the posture of the camera can be determined based on the three-axis gyroscope data, and the motion state of the camera can be determined based on the three-axis acceleration data.

[0082] It is worth noting that the bias data in the bias database are collected by an inertial detection device, and therefore, the bias data in the bias database are all three-axis acceleration data and three-axis gyroscope data.

[0083] The control method of the shooting device provided in the embodiment of the present application can be executed by the control device of the shooting device. In the embodiment of the present application, the control method of the shooting device performed by the control device of the shooting device is taken as an example to illustrate the control device of the shooting device provided in the embodiment of the present application.

[0084] In some embodiments of the present application, a control device for a photographing device is provided. Figure 5 The structure block diagram of the control device of the shooting device provided in the embodiment of the present application is shown as follows: Figure 5 As shown, the control device 500 of the shooting device includes:

[0085] A determination module 502 is used to determine target bias data in a bias database, where the bias database includes historical acquisition data of an inertial detection device;

[0086] An acquisition module 504 is used to acquire first sampling data of an optical image stabilization controller;

[0087] A processing module 506, configured to perform offset elimination on the first sampled data using target offset data;

[0088] The control module 508 is used to control the operation of the driving device according to the first sampling data after the offset is eliminated.

[0089] In the embodiment of the present application, when the shooting device is in operation, the target bias data in the bias database is determined according to the working parameters of the shooting device, and the target bias data is the historical acquisition data of the inertial detection device. Through the target bias data, the first sampling data of the optical image stabilization controller is offset eliminated, and the offset in the output data of the inertial detection device can be filtered out. Through the first sampling data after the offset is eliminated, the operation of the driving device can be accurately controlled, and the camera movement can be accurately controlled to eliminate the jitter during the shooting process.

[0090] It is worth mentioning that the shooting devices include mobile phones, cameras, camcorders, etc.

[0091] In the related art, the data output by the gyroscope in the optical image stabilization system of the shooting device contains a large amount of residual bias data, and a high-pass filter is used to eliminate the bias data. However, in the process of eliminating the bias data through the high-pass filter, some effective low-frequency signals will also be filtered out, resulting in the optical image stabilization system being unable to effectively suppress low-frequency jitter.

[0092] The embodiment of the present application establishes a bias database through the historical collected data of the inertial detection device, and determines the target bias data in the bias database according to the current working condition parameters of the shooting device. After acquiring the first sampling data of the optical image stabilization controller, the first sampling data is offset eliminated through the target bias data, thereby eliminating the bias data in the first sampling data output by the inertial detection device to the optical image stabilization controller while avoiding filtering out the effective low-frequency signal in the first sampling data. Therefore, the driving device can be accurately controlled by the first sampling data after the offset is eliminated, and more low-frequency effective signals of the inertial detection device can be retained during the optical image stabilization process, thereby enabling the optical image stabilization system to effectively suppress the low-frequency jitter of the shooting device.

[0093] In some embodiments of the present application, the acquisition module 504 is further used to acquire first temperature data of the shooting device;

[0094] The determination module 502 is further configured to determine target bias data according to the first temperature data and the bias database.

[0095] The embodiment of the present application determines the target bias data in the bias database based on the first temperature data collected during the operation of the shooting device, ensures that the found target bias data is consistent with the current temperature of the shooting device, and achieves the effect of accurately finding the target bias data in the bias database.

[0096] In some embodiments of the present application, the control device of the photographing device further includes:

[0097] A search module, used for searching corresponding target bias data according to the corresponding relationship when the first temperature data is stored in the bias database;

[0098] The search module is further used to search for temperature range data according to the first temperature data when the first temperature data is not stored in the bias database, the temperature range data being data corresponding to the temperature range in which the first temperature data is located in the bias database;

[0099] The determination module 502 is further configured to determine target offset data according to the temperature data in the temperature range data and the corresponding offset data.

[0100] In the embodiment of the present application, when the first temperature data is obtained, the first temperature data is searched in the bias database. When the bias data corresponding to the first temperature data is found, the bias data is used as the target bias data. When the first temperature data is not found, the target bias data is calculated by the temperature range data corresponding to the first temperature data and the corresponding bias data. The target bias data is made to correspond to the first temperature data collected during the operation of the shooting device, thereby improving the accuracy of the determined target temperature data.

[0101] In some embodiments of the present application, the photographing device further includes an inertia detection controller, and the inertia detection controller is connected to the inertia detection device.

[0102] The acquisition module is further used to acquire second sampling data of the inertia detection controller;

[0103] The acquisition module 504 is further used to acquire second temperature data of the camera when the current posture of the camera is in a preset posture;

[0104] The control device of the shooting device also includes:

[0105] The establishing module is used to establish a bias database according to the second temperature data and second sampling data corresponding to the second temperature data.

[0106] In an embodiment of the present application, when the shooting device is in a standby state, the inertial detection device continuously collects the second sampling data and transmits it to the inertial detection controller. The inertial detection controller monitors the posture of the shooting device according to the second sampling data. When the posture of the shooting device is a preset posture, the current second sampling data and the corresponding temperature data are recorded, thereby realizing the establishment of a bias database and the continuous updating of the bias database when the shooting device is in a standby state.

[0107] In some embodiments of the present application, the determination module 502 is used to determine the current posture of the camera according to the second sampling data.

[0108] The embodiment of the present application monitors the current posture of the shooting device based on the second sampling data collected by the inertial detection device, so that the shooting device can not only determine whether the shooting device is in a preset posture based on the second sampling data, but also establish a bias database based on the second sampling data when the shooting device is in the preset posture.

[0109] In some embodiments of the present application, the inertial detection device includes an acceleration detection device and a gyroscope, and the target bias data includes one or a combination of the following: three-axis acceleration data, three-axis gyroscope data.

[0110] In the embodiment of the present application, the inertial detection device includes a deceleration detection device for detecting acceleration data, and a gyroscope for detecting three-axis gyroscope data. It can be understood that the three-axis gyroscope data is the posture data of the camera. That is, the posture of the camera can be determined based on the three-axis gyroscope data, and the motion state of the camera can be determined based on the three-axis acceleration data.

[0111] It is worth noting that the bias data in the bias database are collected by an inertial detection device, and therefore, the bias data in the bias database are all three-axis acceleration data and three-axis gyroscope data.

After acquiring the first sampling data of the optical image stabilization controller, the first sampling data is offset eliminated through the target bias data, thereby eliminating the bias data in the first sampling data output by the inertial detection device to the optical image stabilization controller while avoiding filtering out the effective low-frequency signal in the first sampling data. Therefore, the driving device can be accurately controlled by the first sampling data after the offset is eliminated, and more low-frequency effective signals of the inertial detection device can be retained during the optical image stabilization process, thereby enabling the optical image stabilization system to effectively suppress the low-frequency jitter of the shooting device.

When the bias data corresponding to the first temperature data is found, the bias data is used as the target bias data. When the first temperature data is not found, the target bias data is calculated by the temperature range data corresponding to the first temperature data and the corresponding bias data.
