Description

Technical Field

[0001] The present invention relates to the field of camera motor technology, and in particular to a camera motor homing method, system, device and storage medium. Background Art

[0002] From the perspective of camera performance, the time taken to exit the camera is an important indicator to measure camera performance. On mobile devices, there are multiple implementations for motor push, but when exiting the camera to release resources, it is necessary to consider the timing relationship between motor push, camera algorithm module resource release, and camera sensor module resource release. It is necessary to perform deinitialization operations on each module of the camera in turn to release the resources they occupy, and control the time taken to exit the camera while ensuring that the motor returns to its normal position.

[0003] In order to avoid the collision sound between modules after the sensor is powered off, most cameras in mobile devices on the market will reset the motor before the sensor is powered off. The motor reset operation when exiting the camera on traditional mobile devices is mostly completed by the algorithm module before the resources are released, and the long motor reset time seriously affects the performance of camera exit.

[0004] Therefore, a new camera motor homing solution is urgently needed to improve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a camera motor reset method, system, device and storage medium, which are used to reduce the impact of the camera motor reset time on the total camera exit time.

[0006] In a first aspect, an embodiment of the present invention provides a camera motor home method, which is applied to a terminal device, wherein a software system of the terminal device includes a hardware abstraction layer module, a data processing algorithm module and a camera driver module, and the method includes: when exiting a camera application, the hardware abstraction layer module obtains home information of the camera motor of the terminal device from the data processing algorithm module; the hardware abstraction layer module transmits the home information of the camera motor to the camera driver module; the camera driver module performs home information of the camera motor through a first thread when exiting the camera application according to the home information of the camera motor; the data processing algorithm module releases data resources occupied by the camera during operation through a second thread; and the first thread and the second thread are parallel in timing.

[0007] The beneficial effect of the camera motor homing method provided by the embodiment of the present invention is that: when exiting the camera application, the hardware abstraction layer module obtains the homing information of the camera motor from the data processing algorithm module, and at this time, the data processing algorithm module can release the data resources occupied by the camera during operation through the second thread. At the same time, the hardware abstraction layer module transmits the homing information of the camera motor to the camera driver module, and the camera driver module performs the motor homing through the first thread according to the homing information of the camera motor, so as to complete the homing operation of the camera motor. In this way, the first thread and the second thread can be parallel in timing, and can release data resources while the camera motor is homing, thereby reducing the impact of the camera motor homing time on the total camera exit time, and improving the performance of the camera when exiting.

[0008] In a possible implementation, the camera motor is reset when the camera application is exited, and further includes: the camera driver module updates the state of the soft landing flag to a completed state. The beneficial effect is that by updating the state of the soft landing flag to a completed state, it is easy to confirm that the motor reset is completed.

[0009] In a possible implementation, after the hardware abstraction layer module transmits the homing information of the camera motor to the camera driver module, the hardware abstraction layer further includes: releasing the system integrated module resources, image sensor module resources, and image read-write module resources occupied by the camera during operation. The beneficial effect is that by releasing the system integrated module resources, image sensor module resources, and image read-write module resources occupied by the camera during operation, it is convenient to reuse resources, save system resources, and thus improve the performance of the camera.

[0010] In a possible implementation, the homing information includes the current position information of the motor, the target position information, the step length of each movement, and the interval time of each movement. The beneficial effect is that the distance that the camera motor needs to move is known through the current position information of the motor and the target position information, and the number of times the camera motor needs to move is obtained through the step length of each movement and the interval time of each movement, so as to facilitate the control of the homing of the camera motor.

[0011] In a second aspect, an embodiment of the present invention provides a camera motor homing system, which is applied to a terminal device, and includes a hardware abstraction layer module, a data processing algorithm module and a camera driver module, including: when exiting the camera application, the hardware abstraction layer module is used to obtain the homing information of the camera motor of the terminal device from the data processing algorithm module; the hardware abstraction layer module is also used to transmit the homing information of the camera motor to the camera driver module; the camera driver module is used to perform the homing of the camera motor through a first thread when exiting the camera application according to the homing information of the camera motor; the data processing algorithm module is used to release the data resources occupied by the camera during operation through a second thread; the first thread and the second thread are parallel in timing.

[0012] In a possible implementation, after the camera driving module resets the camera motor, it is further configured to: update the status of the soft landing flag to a completion status.

[0013] In a possible implementation, after the hardware abstraction layer transmits the homing information of the camera motor to the camera driver module, it is also used to: release the system integration module resources, image sensor module resources and image reading and writing module resources occupied by the camera during operation.

[0014] In a possible implementation, the homing information includes current position information of the motor, target position information, a step length of each movement, and an interval time of each movement.

Among them:

[0030] The hardware abstraction layer module 101 is used to obtain the homing information of the camera motor from the data processing algorithm module when exiting the camera application, and is also used to transmit the homing information of the camera motor to the camera driver module. For example, the hardware abstraction layer module 101 is the camera hardware abstraction layer (camera HAL) in the Android architecture.

[0031] The camera driver module 103 is used to perform motor reset when exiting the camera application according to the reset information of the camera motor through the first thread. In some embodiments, the camera driver module 103 is a device driver layer of the camera in the Android architecture.

[0032] The data processing algorithm module 102 is used to release the data resources occupied by the camera during operation through the second thread; the first thread and the second thread are parallel in timing. In some embodiments, the data processing algorithm module 102 is an image signal processing algorithm module (Image Signal Processing, ISP).

[0033] Combination Figure 1 The software system architecture of the terminal device shown in FIG. 1 is a method for homing a camera motor provided by an embodiment of the present invention. Figure 2 As shown, the method includes the following steps.

[0034] S201, when exiting the camera application, the hardware abstraction layer module 101 obtains the homing information of the camera motor of the terminal device from the data processing algorithm module 102;

After the hardware abstraction layer module 101 obtains the homing information of the camera motor, the data processing algorithm module 102 can release the data resources occupied by the camera during operation through the second thread, that is, release the resources occupied by the data processing algorithm module 102. At the same time, after the hardware abstraction layer module 101 obtains the homing information of the camera motor, the hardware abstraction layer module 101 transmits the homing information of the camera motor to the camera driver module 103, and then the camera driver module 103 performs the homing operation of the camera motor through the first thread according to the homing information of the camera motor.

[0041] In some embodiments, the hardware abstraction layer module 101 transmits the homing information of the camera motor to the camera driver module 103, specifically including: the hardware abstraction layer module 101 transmits the homing information of the camera motor to the image sensor module 105, and returns after completion. The image sensor module 105 transmits the received homing information of the camera motor to the camera driver module 103.

[0042] In some embodiments, the first thread and the second thread are executed in parallel in terms of timing, that is, the first thread and the second thread are executed separately.

[0043] It is worth noting that there is no strict sequence between S202 and S204 in the above steps.

[0044] In some embodiments of the present invention, after the hardware abstraction layer module 101 transmits the homing information of the camera motor to the camera driver module 103, it also includes: the hardware abstraction layer releases the resources of the system integration module 104, the image sensor module 105 and the image reading and writing module 106 occupied by the camera during operation.

[0045] In some specific embodiments of the present invention, after the hardware abstraction layer module 101 transmits the homing information of the camera motor to the camera driver module 103, the hardware abstraction layer module 101 releases the resources of the system integration module 104, the image sensor module 105 and the image reading and writing module 106 occupied by the camera during operation, and the order of releasing the resources of the system integration module 104, the image sensor module 105 and the image reading and writing module 106 is not particular.

[0046] In some embodiments, after the hardware abstraction layer module 101 transmits the homing information of the camera motor to the camera driver module 103 , the hardware abstraction layer module 101 releases the resources of the image sensor module 105 , and returns after completing the resource release of the image sensor module 105 .

[0048] In some other embodiments, after the hardware abstraction layer module 101 transmits the homing information of the camera motor to the camera driver module 103, the hardware abstraction layer module 101 releases the resources of the image reading and writing module 106, and returns after completing the release of the resources of the image reading and writing module 106.

[0049] In some embodiments of the present invention, the camera motor is reset when exiting the camera application, and further includes: the camera driver module 103 updates the status of the soft landing flag to a completion status.

[0050] In some specific embodiments of the present invention, after the camera motor is homed, the camera driver module 103 updates the state of the soft landing flag to a completion state, so as to know that the homed action of the camera motor is completed.

[0051] In some other embodiments, when the hardware abstraction layer module 101 releases the resources of the image sensor module 105, the hardware abstraction layer module 101 checks the state of the soft landing flag, and when the state of the soft landing flag is in the completed state, the resource release operation of the image sensor module 105 is completed. In this way, the state of the soft landing flag can be checked, so that the resource release of the image sensor module 105 is marked after completion, ensuring that the camera motor completes the homing action when the resources are released.

[0052] In some embodiments of the present invention, the homing information includes the current position information of the motor, the target position information, the step length of each movement, and the interval time of each movement.

[0053] In some specific embodiments of the present invention, the number of times the motor is pushed during the motor homing process can be obtained through the motor current position information and the target position information, so as to facilitate the control of the camera motor.
