Background

In the shooting process, if the obtained shot picture is not clear enough and has double images or fuzzy situations, except that the camera cannot be focused normally in the shooting process, the camera shakes during the shooting process.

In the related art, in order to improve the anti-shake capability of the terminal, a plurality of optical image stabilizers are adopted in the terminal to acquire anti-shake data for correction. However, in the correction process, since manufacturers of a plurality of optical image stabilizers configured for the terminal are different, when acquiring jitter data of the terminal, the anti-jitter data acquired between the optical image stabilizers may not be identical, and thus, when performing correction, it is easy to cause unsatisfactory improvement of picture quality, which affects user experience.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the related art, in order to ensure that a picture is clear when a terminal shoots and overcome the phenomenon that the terminal shakes, a plurality of optical image stabilizers are configured in the terminal, and then adjustment is performed according to obtained shaking data through each optical image stabilizer. However, during the adjustment process, each optical image stabilizer directly acquires the anti-shake data of the terminal. Due to the fact that the information frequency and the information quantity obtained by each optical image stabilizer are different, when the picture is improved, the effect is not ideal, and the use experience of a user is affected.

In view of this, the present disclosure provides an anti-shake data obtaining method, which can determine a synchronization state of each optical image stabilizer based on a communication bus state of each optical image stabilizer, and further control each optical image stabilizer to obtain anti-shake data at the same time, so that the anti-shake data obtained by each optical image stabilizer are the same, thereby improving the quality of a shot picture and improving the user experience.

The anti-shake data acquisition method provided by the disclosure is applied to a terminal which comprises a plurality of optical image stabilizers. In one example, the category of terminals may include mobile terminals, such as: cell phones, tablets, notebooks, etc. In another example. The structure of the terminal may include: a dual-screen terminal, a folding screen terminal, a full-screen terminal, etc.

Fig. 1 is a flowchart illustrating an anti-shake data acquisition method according to an exemplary embodiment, and as shown in fig. 1, the anti-shake data acquisition method includes the following steps S11 to S12.

In step S11, the communication bus status of the plurality of optical image stabilizers is monitored.

In the embodiment of the present disclosure, when the terminal performs anti-shake using a plurality of optical image stabilizers, the anti-shake is performed by controlling the plurality of optical image stabilizers to uniformly acquire anti-shake data. The manufacturers and the operation modes of the respective optical image stabilizers may be different from each other in the same terminal. Therefore, before each optical image stabilizer is controlled to synchronously acquire anti-shake data, the working mode state of the communication protocol bus configured by the controller of each optical image stabilizer is detected in real time in advance, and then the communication protocol bus state of each optical image stabilizer is monitored, so that each optical image stabilizer can acquire the anti-shake data under different working modes.

In the present disclosure, the communication protocol bus may employ a Serial Peripheral Interface (SPI). SPI is a synchronous communication bus capable of supporting high-speed data transmission, full duplex. Under different working mode states, the level and phase state of the communication protocol bus corresponding to the state when the anti-shake data can be acquired are different. Before the anti-shake data are synchronously sent to each optical image stabilizer, the terminal can communicate with the controller of the optical image stabilizer by full duplex, so that the communication protocol bus state of each optical image stabilizer can be conveniently determined, and the state synchronization of the anti-shake data acquired by the plurality of optical image stabilizers can be conveniently determined. The operation modes may include: in the mode 0, the mode 1, the mode 2, and the mode 3, the corresponding Clock Polarity (CPOL) and the Clock Phase (CPHA) are different in different operation modes. For example: in mode 0, CPOL ═ 0 and CPHA ═ 0; in mode 1, CPOL ═ 0 and CPHA ═ 1; in mode 2, CPOL ═ 1 and CPHA ═ 0; in mode 3, CPOL is 1 and CPHA is 1. Therefore, during monitoring, the state synchronization of each optical image stabilizer for acquiring the anti-shake data can be determined according to the clock polarity corresponding to the optical image stabilizer and the state of the optical image stabilizer for acquiring the anti-shake data configured corresponding to the clock phase.

In step S12, in response to determining state synchronization of the plurality of optical image stabilizers acquiring the anti-shake data based on the communication bus state, the optical image stabilizers are controlled to acquire the anti-shake data in synchronization.

In the embodiment of the disclosure, the state synchronization of each optical image stabilizer for acquiring anti-shake data is determined according to the communication bus state corresponding to each optical image stabilizer. And further controlling each optical image stabilizer to uniformly and synchronously acquire the anti-shake data under the condition that the state of acquiring the anti-shake data by each optical image stabilizer is synchronous. Therefore, the purpose of synchronously updating the anti-shake data among the optical image stabilizers is achieved, the anti-shake data acquired by the optical image stabilizers are the same, the shooting quality of a shot picture is improved, and the use experience of a user is improved.

Through the embodiment, the anti-shake data can be synchronously updated to each optical image stabilizer based on the monitored communication bus state of each optical image stabilizer, so that the anti-shake data acquired by each optical image stabilizer are the same, the image quality shot by the terminal is improved, and the use experience of a user is improved.

Based on the same conception, the embodiment of the disclosure also provides another anti-shake data acquisition method. And the acquired anti-shake data and the anti-shake data sent to the optical image stabilizer are stored separately, so that the optical image stabilizer is prevented from obtaining null data or error data.

Fig. 2 is a flowchart illustrating another anti-shake data acquisition method according to an exemplary embodiment, and as shown in fig. 2, the anti-shake data acquisition method includes the following steps S21 to S24.

In step S21, the anti-shake data is stored in the first memory.

In the embodiment of the disclosure, based on the use of a camera application in a terminal, anti-shake data generated when the terminal performs shooting is acquired and stored in a first memory, so that a sufficient amount of anti-shake data is obtained. The acquired anti-shake data are stored and then transmitted, so that the current camera application can be determined to be in use according to the acquired anti-shake data, and the shake state of the terminal can be determined. And the anti-shake data is stored in the first memory first, so that the anti-shake data can be prevented from being lost in the process of determining the state synchronization of the anti-shake data acquired by each optical image stabilizer, and the optical image stabilizers can acquire complete anti-shake data conveniently.

In step S22, in response to the first memory storing the anti-shake data being full, the anti-shake data stored in the first memory is updated and stored to the second memory.

In the embodiment of the present disclosure, after the first memory is full of the anti-shake data, all the anti-shake data stored therein is sent to the second memory, so as to update the anti-shake data stored in the second memory. So that the anti-shake data is transmitted to the optical image stabilizers, respectively, through the second memory. And further, the phenomenon that the optical image stabilizer acquires null data or wrong anti-shake data due to the fact that the storage speed of the stored anti-shake data is different from the acquisition speed of the optical image stabilizer acquiring the anti-shake data is avoided. Thereby improving the accuracy of the anti-shake data acquired by the optical image stabilizer.

In step S23, the communication bus status of the plurality of optical image stabilizers is monitored.

In step S24, in response to determining state synchronization of the plurality of optical image stabilizers acquiring the anti-shake data based on the communication bus state, each optical image stabilizer is controlled to acquire the anti-shake data stored in the second memory from the second memory in synchronization.

In an example, a Random Access Memory (RAM) may be employed as the first Memory, the second Memory, or both the first Memory and the second Memory. The RAM is an internal memory that directly exchanges data with a terminal Central Processing Unit (CPU). It can be read and written at any time (except for refreshing), and has high speed, and is usually used as a temporary data storage medium of an operating system or other programs in operation. When the RAM is operated, information can be written (stored) or read (retrieved) from any one of designated addresses at any time. And then when using RAM to carry out data transmission, can be fast with anti-shake data transmission to next communication protocol bus.

In an implementation scene, in the terminal shooting process, anti-shake data monitored by the terminal camera application in the use process is acquired and transmitted to the first memory. And informing the second memory after the anti-shake data in the first memory is full, responding by the second memory, acquiring the latest anti-shake data from the first memory, and updating and storing the internal anti-shake data. And after the state synchronization of the optical image stabilizers for acquiring the anti-shake data is determined according to the monitoring of the communication bus state of each optical image stabilizer, each optical image stabilizer is controlled to acquire the anti-shake data stored in the second memory through the second memory after data updating.

Based on the same conception, the embodiment of the disclosure also provides another anti-shake data acquisition method. In order to ensure that the anti-shake data acquired by each optical image stabilizer are the same, and avoid confusion when the anti-shake data is acquired by each optical image stabilizer due to updating of the anti-shake data, when the optical image stabilizer acquires the anti-shake data through the second memory, the first memory of the terminal is interrupted to transmit the updated anti-shake data to the second memory, and then the risk caused by registering and re-acquiring the anti-shake data is prevented.

Fig. 3 is a flowchart illustrating still another anti-shake data acquisition method according to an exemplary embodiment, and as shown in fig. 3, the anti-shake data acquisition method includes the following steps S31 to S35.

In step S31, the anti-shake data is stored in the first memory.

In step S32, in response to the first memory storing the anti-shake data being full, the anti-shake data stored in the first memory is updated and stored to the second memory.

In step S33, the communication bus status of the plurality of optical image stabilizers is monitored.

In step S34, in response to determining state synchronization of the plurality of optical image stabilizers acquiring the anti-shake data based on the communication bus state, each optical image stabilizer is controlled to acquire the anti-shake data stored in the second memory from the second memory in synchronization.

In step S35, updating and storing the anti-shake data stored in the first memory into the second memory is interrupted when the optical image stabilizers are controlled to synchronously acquire the anti-shake data.

In the embodiment of the disclosure, in order to avoid that the obtaining amount of the anti-shake data is different when the anti-shake data is obtained by each optical image stabilizer in the same period of time due to different working modes, when the anti-shake data is synchronously obtained by controlling each optical image stabilizer, the process of updating and storing the anti-shake data stored in the first memory into the second memory is interrupted, and then the anti-shake data obtained by each optical image stabilizer is ensured to be the same. And the updating of the anti-shake data in the second memory is interrupted, so that the phenomenon that the anti-shake data acquired by the optical image stabilizer is incomplete or new and old anti-shake data are confused is avoided. Therefore, the accuracy of acquiring anti-shake data by each optical image stabilizer is improved, and the effectiveness and the accuracy are improved when a shot picture is corrected subsequently.

Based on the same conception, the embodiment of the disclosure also provides another anti-shake data acquisition method.

Fig. 4 is a flowchart illustrating still another anti-shake data acquisition method according to an exemplary embodiment, and as shown in fig. 4, the anti-shake data acquisition method includes the following steps S41 through S46.

In step S41, the anti-shake data is stored in the first memory.

In step S42, the transfer permission flag is set in response to the first memory storing the anti-shake data being full.

In the embodiment of the disclosure, the terminal responds after the first memory is full of the anti-shake data, and sets a transmission permission flag in the communication protocol bus where the first memory is located, so as to prompt that the current first memory is full of the anti-shake data, and can transmit the anti-shake data stored in the first memory to the second memory, thereby updating the anti-shake data stored in the second memory.

In step S43, in response to the first memory storing the anti-shake data being full, the anti-shake data stored in the first memory is updated and stored to the second memory.

In step S44, the communication bus status of the plurality of optical image stabilizers is monitored.

In step S45, in response to determining the state synchronization of the plurality of optical image stabilizers for acquiring the anti-shake data based on the communication bus state, control of the respective optical image stabilizers for synchronously acquiring the anti-shake data stored in the second memory from the second memory is started based on the transmission permission flag.

In step S46, updating and storing the anti-shake data stored in the first memory into the second memory is interrupted when the optical image stabilizers are controlled to synchronously acquire the anti-shake data.

With the above-described embodiment, based on the set transmission permission flag, it can be determined that the anti-shake data in the first memory is full, the first memory is ready, the anti-shake data can be transmitted to the second memory, and the anti-shake data in the second memory is updated.

In one embodiment, whether the first memory is full of a plurality of anti-shake data may be determined based on monitoring for a specified time period. Data request access to the first memory is periodically performed according to a specified time period, and monitoring is performed based on a response of the first memory. If it is determined, based on the monitoring, that the first memory agrees to transfer the anti-shake data update stored in the first memory to the second memory, it may be determined that the first memory is full of a plurality of anti-shake data. For example: data request accesses are made to the first memory every 1.67 microseconds (μ s) until it is determined that the first memory grants transmission of anti-shake data updates stored in the first memory to the second memory.

In another embodiment, the state synchronization of the anti-shake data acquired by the plurality of optical image stabilizers may be determined based on the communication bus state correspondence of each optical image stabilizer being the chip select idle state. Based on the foregoing, the communication bus state of the optical image stabilizer has four operation mode states. Further, the monitoring may be performed based on a detected chip select signal in the communication bus of each optical image stabilizer. If the chip selection corresponding to each optical image stabilizer is detected to be high level, the communication bus state of each optical image stabilizer can be determined to be in an idle state, and further the state synchronization of each optical image stabilizer for acquiring anti-shake data can be determined. At this time, the optical image stabilizers can be controlled to synchronously acquire the anti-shake data. For example: a communication bus timing chart as shown in fig. 5, in which: a chip select signal, a clock signal, and a data signal. If the communication bus state of the chip selection signal of each optical image stabilizer is as high level as that corresponding to the chip selection signal in the first area, the communication bus state representing each optical image stabilizer is in an idle state, and then each optical image stabilizer can be controlled to synchronously acquire anti-shake data for updating. If the communication bus state of each optical image stabilizer is as shown in the second area, and the chip select signal is at a low level, each optical image stabilizer is in a latch state, and each optical image stabilizer does not acquire the anti-shake data and does not update the anti-shake data. The state of a communication bus of the chip selection signal is determined by detecting a clock signal in a fixed period, and anti-shake data is stored in the memory, so that when all the optical image stabilizers can acquire the anti-shake data at the same time, all the anti-shake data in the memory is sent to all the optical image stabilizers. Therefore, the state synchronization of the plurality of optical image stabilizers for acquiring the anti-shake data can be effectively controlled.

In yet another embodiment, the anti-shake data includes: acceleration data of the terminal and gravity angular velocity data of the terminal. The method comprises the steps of obtaining acceleration data of a terminal based on an acceleration sensor configured in the terminal, and obtaining gravity angular velocity data of the terminal based on data obtained by a gyroscope sensor configured in the terminal. Based on shooting of camera application, acceleration data are obtained through an acceleration sensor, gravity angular velocity data are obtained through a gyroscope sensor, and then anti-shake data of the terminal in the shooting process are obtained. Because the working frequency cycles of the acceleration sensor and the gyroscope sensor are different when the acceleration sensor and the gyroscope sensor acquire data, in order to avoid disorder of anti-shake data when the anti-shake data are stored, the acceleration data are identified through a first specified identifier and then stored in a first storage space of a first storage device, and the gravity angular velocity data are identified through a second specified identifier and then stored in a second storage space of the first storage device. Thereby distinguishing acceleration data from gravity angular velocity data based on the specified identification. In one example, when the anti-shake data is updated to the second memory, the acceleration data may be identified by the first specified identifier and then stored in the third storage space of the second memory, and the gravity angular velocity data may be identified by the second specified identifier and then stored in the fourth storage space of the second memory, which is further helpful for avoiding confusion of the anti-shake data.

In one example, the plurality of optical stabilizers are controlled to acquire anti-shake data based on a Micro Controller Unit (MCU) in the terminal. The MCU is also called a Single Chip Microcomputer (MCU) or a Single Chip Microcomputer (MCU), and is a Chip-level computer formed by appropriately reducing the frequency and specification of a Central Processing Unit (CPU), and integrating peripheral interfaces such as a memory (memory), a counter (Timer), a USB, an a/D converter, a UART, a PLC, a DMA, and even an LCD driving circuit on a Single Chip, so as to perform different combination controls for different applications.

In an implementation scenario, a system architecture for performing anti-shake data synchronous update based on multiple light ray image stabilizers inside a terminal may be as shown in the system architecture diagram shown in fig. 6. Based on the use that the camera was used, acquire anti-shake data through acceleration sensor and gyroscope sensor, and then with anti-shake data transmission to MCU, acquire anti-shake data by a plurality of optical image stabilizer of MCU control.

In another implementation scenario, based on the system architecture, a process of transmitting the anti-shake data in the system architecture may be as shown in the data transmission diagram shown in fig. 7. The MCU includes a first memory and a second memory. And the acceleration sensor and the gyroscope sensor send the acquired anti-shake data to the first memory for updating and saving. And after the anti-shake data in the first memory is full, transmitting the anti-shake data in the first memory to the second memory so as to update the anti-shake data in the second memory. And after the MCU determines that the plurality of optical image stabilizers acquire the anti-shake data synchronously based on monitoring, the MCU controls to send the anti-shake data stored in the second memory to each optical image stabilizer so as to control each optical image stabilizer to acquire the anti-shake data synchronously.

In one example, to ensure effectiveness and accuracy of picture quality correction during picture taking, an acceleration sensor and a gyroscope sensor are used to acquire anti-shake data during the process of acquiring anti-shake data by each optical image stabilizer. After the anti-shake data of each optical image stabilizer are updated, controlling the acceleration sensor and the gyroscope sensor to acquire the anti-shake data corrected by the optical image stabilizer. And then effectively avoid the anti-shake data to correct the confusion, improve and correct efficiency.

In yet another implementation scenario, the process of updating the anti-shake data may be as shown in the software flowchart shown in fig. 8.

In step S51, the optical image stabilizer transmits a request for acquiring anti-shake data.

In step S52, in response to the request to acquire the anti-shake data, the update of the anti-shake data is interrupted.

In step S53, the anti-shake data in the fifo chip is transferred and sent to the communication protocol bus apparatus.

In the embodiment of the present disclosure, a First-in First-out (FIFO) chip is a novel large-scale integrated circuit, and the FIFO chip has the characteristics of flexibility, convenience, and high efficiency, and is widely applied to high-speed data acquisition, high-speed data processing, high-speed data transmission, and multi-computer processing systems. In the present disclosure, the process of the optical image stabilizer acquiring the anti-shake data may be completed in the FIFO.

In yet another implementation scenario, a specific flow of updating the anti-shake data may be as shown in the software flowchart shown in fig. 9.

In step S601, a request for acquiring anti-shake data is periodically transmitted to the first memory every 1.67 μ sec.

In step S602, in response to the request for obtaining the anti-shake data, the update of the anti-shake data is interrupted.

In step S603, the enable flag is set in the process of interrupting updating the anti-shake data.

In step S61, it is determined whether the MCU is allowed to acquire the anti-shake data in the acceleration sensor and the gyro sensor. If yes, go to step S62; if not, judging again.

In step S62, anti-shake data in the acceleration sensor and the gyro sensor is acquired.

In step S63, it is determined whether or not the chip selection of each optical image stabilizer is in an idle state. If yes, go to step S64; if not, judging again.

In step S64, the anti-shake data in the FIFO is updated, and the corrected anti-shake data is reconfigured for the acceleration sensor and the gyro sensor.

Based on the same conception, the embodiment of the disclosure also provides an anti-shake data acquisition device.
