Embodiment 1
[0053] An embodiment of the present invention provides a camera module, which can perform auto-focus control according to received direction information of the camera module, and reduce power consumption while improving response time.
[0054] figure 1 It is a schematic diagram of the composition of the camera module of an embodiment of the present invention, please refer to figure 1 , the camera module consists of:
[0055] The memory 11 stores focus driving information when the camera module is in different directions.
[0056] Lens drive unit 12, which receives the direction information of the camera module sent by the sensor, calls the focus drive information corresponding to the direction information stored in the memory 11 according to the method information, and drives the lens group to perform autofocus according to the focus drive information ;
[0057] The lens group 13 performs automatic focusing according to the driving of the lens driving unit 12 .
[0058] In...
Embodiment 2

Figure 5 is a schematic diagram of the composition of the electronic device, the electronic device includes a sensor and a camera module 51, and the camera module performs auto-focus control according to the direction information of the camera module sent by the sensor.
[0079] Please refer to Figure 5 , in one embodiment, the camera module includes:
[0080] a memory 511, which stores focus driving information of the camera module 51 in different directions;
[0081] A lens driving unit 512, which receives the direction information of the camera module 51 sent by the sensor, calls the focus drive information corresponding to the direction information stored in the memory 511 according to the direction information, and drives the lens group according to the focus drive information. auto focus;
[0082] The lens group 513 performs automatic focusing according to the driving of the lens driv...
Embodiment 3
[0087] The embodiment of the present invention also provides an automatic focusing method. Figure 6 It is a schematic diagram of the composition of the method, which is applied to an electronic device with a camera module, please refer to Figure 6 , the method includes:
[0088] Step 601: The lens driving unit of the camera module receives the direction information of the camera module sent by the sensor;
[0089] Wherein, after the sensor senses the direction of the camera module, it can be sent to the lens driving unit of the camera module. The sensor here may be a sensor of a camera module, or a sensor of the electronic device.
[0090] Step 602: According to the orientation information of the camera module, the lens driving unit of the camera module invokes the focus drive information corresponding to the orientation information stored in the memory of the camera module;
[0091] Wherein, the lens driving unit of the camera module calls the focus driving information c...
