Problems solved by technology

However, the multi-functional design leads to the limitation of the volume of the mobile phone, so most of the camera modules in the mobile phones with the shooting function are fixed focal lengths, and the fixed focal length camera modules are very important for imaging, especially close-up shooting. It is easy to cause inability to focus clearly, which will greatly affect the shooting effect of mobile phone cameras

Abstract

The invention relates to a camera module which comprises a circuit board, an image sensor and a lens module. The lens module comprises a first optical lens, a second optical lens, a third optical lens, a liquid lens and a micro-actuator actuator. The micro-actuator comprises a fixing part and a movement part which is provided with a through hole in which the first optical lens is embedded. The fixing part, the movement part and the image sensor are connected electrically. The second optical lens is connected to the third optical lens. The liquid lens embedded between the second optical lens and the third optical lens is connected to the image sensor. Rays are imagined on the image sensor through the first optical lens, the second optical lens and the third optical lens in turn. When the circuit board is electrified, an electrostatic force is generated due to an electric potential difference between the movement part and the fixing part so as to drive the movement part to move along the lens module optical axis for automatic focus.

Description

technical field [0001] The invention relates to the field of imaging, in particular to a camera module for portable electronic devices. Background technique [0002] At present, the trend of mobile phones towards integrated multifunctional development is becoming more and more obvious. In addition to common communication functions, they also add functions such as audio-visual playback and shooting. Especially, mobile phones with shooting functions are very popular among consumers once they are launched. welcome. However, the multi-functional design leads to the limitation of the volume of the mobile phone, so most of the camera modules in the mobile phones with the shooting function are fixed focal lengths, and the fixed focal length camera modules are very important for imaging, especially close-up shooting. It is easy to cause a situation that cannot be clearly focused, which will greatly affect the shooting effect of the mobile phone camera. Therefore, designing a camer...
