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.
Fig. 1 is a schematic structural diagram of a camera head assembly in the related art. As shown in fig. 1, the camera assembly a includes a spatial attitude sensor a4, a first camera a1, a second camera a2, and an anti-shake control module A3. The anti-shake control module A3 is connected to the spatial attitude sensor a4, and is configured to receive spatial attitude information of the camera assembly a acquired by the spatial attitude sensor a4, and control the first camera a1 to implement an anti-shake function according to the spatial attitude information.
In the above-mentioned related art, the anti-shake control module A3 can only carry out anti-shake control to the first camera a1 that is responsible for the main shooting function alone, and need use the shooting content of two lens modules in the actual shooting process, if the shooting content of second camera a2 causes not good effect because of shaking, will directly influence the final shooting effect of camera assembly a.
To solve the problems in the related art, the present disclosure improves the structure of the camera assembly a, and the following description is provided:
fig. 2 is a schematic structural diagram of a camera head assembly according to an exemplary embodiment of the present disclosure. As shown in fig. 2, the camera head assembly 1 may include: a first camera 11 and a second camera 12. Wherein, first camera 11 includes: a first lens module 111, a spatial attitude sensor 113 and a first anti-shake control module 112. The first anti-shake control module 112 is connected to the spatial attitude sensor 113, and is configured to receive spatial attitude information of the camera assembly 1 acquired by the spatial attitude sensor 113, and perform anti-shake control on the first lens module 111 according to the spatial attitude information. The second camera 12 includes: a second lens module 121 and a second anti-shake control module 122. The second anti-shake control module 122 is connected to the first anti-shake control module 112 to obtain second lens motion data, and performs anti-shake control on the second lens module 121 according to the second lens motion data.
In the above-described embodiment, the spatial attitude sensor 113 may include at least one of a gyroscope and an acceleration sensor. The gyroscope is an angular motion detection device which uses a momentum moment sensitive shell of a high-speed revolving body to rotate around one or two axes which are orthogonal to a rotation axis relative to an inertia space, and can sense the deflection angle of an object to be detected. The acceleration sensor is a sensor capable of measuring acceleration, and in the acceleration process, the acceleration sensor measures the inertia force borne by an object to be measured, and calculates and obtains an acceleration value by utilizing a Newton's second law, so that the offset distance of the object to be measured in the specified direction can be sensed. When the above-described spatial attitude sensor 113 includes a gyroscope, the deflection angle of the camera assembly 1 with respect to the X and Y axes can be acquired. When the above-described spatial attitude sensor 113 includes an acceleration sensor, the offset distances of the camera assembly 1 with respect to the X and Y axes can be acquired. In both cases, the camera assembly 1 can achieve 2-axis optical anti-shake. When the above-described spatial attitude sensor 113 includes both a gyroscope and an acceleration sensor, the deflection angle and the offset distance of the camera assembly 1 with respect to the axis X, Y can be acquired, and therefore, the camera assembly 1 can realize 4-axis optical anti-shake in this case.
It should be noted that "first" and "second" in the first camera 11 and the second camera 12 are used to indicate and distinguish any two cameras. Similarly, "first" and "second" of the first lens module 111 and the second lens module 121 are used to represent and distinguish any two lens modules. The "first" and "second" in the first anti-shake control module 112 and the second anti-shake control module 122 are used to represent and distinguish any two anti-shake control modules. The above-mentioned "first" and "second" do not form a limitation on the number of the cameras, the lens modules, and the anti-shake control module.
In the above embodiment, since the user has different requirements for the use of the dual cameras under different conditions, as shown in fig. 2, when the user wishes to simultaneously turn on the first camera 11 and the second camera 12 for shooting, the first anti-shake control module 112, the first lens module 111, the second anti-shake control module 122, and the second lens module 121 may be turned on. At this time, the first anti-shake control module 112 is connected to the spatial attitude sensor 113, receives the spatial attitude information of the camera assembly 1 acquired by the spatial attitude sensor 113, and performs anti-shake control on the first lens module 111 according to the spatial attitude information. The second anti-shake control module 122 is connected to the first anti-shake control module 112 to obtain second lens motion data, and performs anti-shake control on the second lens module 121 according to the second lens motion data.
As shown in fig. 3a, when the user wants to turn on the first camera 11 alone for taking a picture, the second anti-shake control module 122 may be turned off. At this time, the first anti-shake control module 112 is connected to the spatial attitude sensor 113, receives the spatial attitude information of the camera assembly 1 acquired by the spatial attitude sensor 113, and performs anti-shake control on the first lens module 111 according to the spatial attitude information.
As shown in fig. 3b, when the user wants to turn on the second camera 12 alone for shooting, the first lens module 111 can be turned off, and the first anti-shake control module 112 and the second anti-shake control module 122 can be turned on at the same time. At this time, the first anti-shake control module 112 is connected to a spatial attitude sensor 113, and receives spatial attitude information of the camera assembly 1 acquired by the spatial attitude sensor 113. The second anti-shake control module 122 is connected to the first anti-shake control module 112 to obtain second lens motion data, and performs anti-shake control on the second lens module 121 according to the second lens motion data.
In both cases shown in fig. 3a and 3b, the first anti-shake control module 112 may include an SPI data interface to transmit the second lens movement data to the second anti-shake control module 122. Since the transmission speed of the SPI may reach 10Mbps, the receiving of the spatial posture information by the first anti-shake control module 112 and the receiving of the second lens movement data by the second anti-shake control module 122 may be regarded as being performed synchronously.
In the above embodiments, the spatial attitude sensor 113 may include the first kind of output interface and the second kind of output interface. The first type of output interface corresponds to the first anti-shake control module 112, so as to transmit spatial attitude information for the camera assembly 1. The second type output interface is communicated with the electronic equipment mainboard to realize the space attitude control function. It should be noted that the spatial attitude control function may include a horizontal screen and vertical screen switching function for the electronic device, or a spatial attitude sensing function used in an operation process of the electronic device, and this disclosure does not specifically limit this function. It should be noted that, the first type of output interface may include an SPI interface, and the second type of output interface may include an SPI interface or an I2C interface, and the disclosure does not limit the interface types of the first type of output interface and the second type of output interface.
In the above embodiment, the first anti-shake control module 112 and the second anti-shake control module 122 may include: such as controllers 1122, 1222 and drivers 1121, 1221 shown in fig. 4a, 4 b. The controllers 1122 and 1222 are connected to the spatial attitude sensor 113 to receive spatial attitude information for the camera head assembly 1, and issue a first motion control command according to the spatial attitude information. The drivers 1121, 1221 are connected to the controllers 1122, 1222 to obtain the first motion control command, and drive the first lens module 111 according to the first motion control command to implement an anti-shake function. The controllers 1122 and 1222 may include feedback modules 1124 and 1224 and master modules 1123 and 1223 shown in fig. 5a and 5b, the feedback modules 1124 and 1224 may obtain the spatial attitude information corrected by the camera head assembly 1, and send the spatial attitude information to the master modules 1123 and 1223 without any delay, so that the master modules 1123 and 1223 send a second motion control command to the drivers 1121 and 1221. The feedback modules 1124 and 1224 improve the real-time performance of the anti-shake control of the camera assembly 1, and further improve the overall anti-shake effect of the camera assembly 1. It should be noted that the feedback modules 1124 and 1224 of the first camera 11 and the second camera 12 can both detect the spatial attitude information corrected by the camera head assembly 1 through a frequency of 5khz, so that the feedback efficiency between the two feedback modules 1124 and 1224 differs by at most one cycle, i.e. 200us, and such difference can be regarded as that the feedback operations of the two feedback modules 1124 and 1224 are performed synchronously. In addition, the drivers 1121, 1221 described above may include a voice coil motor, and the present disclosure does not limit the driving apparatus.
The present disclosure further proposes an electronic device comprising the above-described camera assembly 1. It should be noted that the electronic device may include a mobile phone, a tablet computer, and the like, and the disclosure is not limited thereto.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
