Problems solved by technology
However, these functions are currently realized by moving the lens with the voice coil focus motor, but at the same time, new problems that are difficult to solve have arisen. For example, the motor is difficult to be completely dust-proof, so during use, the image sensor surface May be scrapped due to falling dust
In addition, the motor needs a matching lens to form a camera module, so the design of the modified motor limits the design of the lens
At the same time, a small motor cannot match a large lens
Furthermore, the optical image stabilization motor can only realize the anti-shake compensation in two directions, but the shake in the actual photo is in three directions, so the existing camera module cannot solve the anti-shake compensation in the three directions

Embodiment Construction
[0018] The structural principle of the present invention will be described below in conjunction with the accompanying drawings and embodiments.
[0019] like figure 1 As shown, the mobile terminal camera module of the present invention includes a lens 1 arranged in sequence, a voice coil motor 2 for fixing or controlling the movement of the lens, an image sensor 303 for imaging, an FPC soft board 309, a drive module, and a lens The light of 1 is transmitted to the image sensor 303 for imaging, and the driving module has a coil and a magnet. The coil and the magnet generate force to drive the image sensor to achieve focusing, and can also drive the image sensor to move horizontally or vertically in a plane perpendicular to the optical axis. To achieve two-dimensional optical image stabilization, further, it can also drive the image sensor to rotate around its exact center in a plane perpendicular to the optical axis. The invention keeps the lens still while moving the image se...

The invention discloses a camera module for a mobile terminal, which includes a lens arranged in sequence, a voice coil motor for fixing the lens or controlling the movement of the lens, an image sensor for imaging, and an FPC soft board. The soft board is movably connected, and the module also includes a drive module, the drive module has a coil and a magnet, and the force generated by the coil and the magnet drives the image sensor to reciprocate in a direction parallel to the optical axis to realize the autofocus function or perpendicular to the optical axis. Transverse or vertical movement in the plane of the optical axis and rotation around the center point to achieve three-dimensional optical image stabilization. The invention also proposes a mobile terminal using the camera module. The invention has simple structure, small volume and convenient matching.
Description
technical field [0001] The invention relates to accessories of electronic products, in particular to a camera module of a mobile terminal and the mobile terminal. Background technique [0002] At present, various types of mobile terminal products emerge in endlessly, and their respective functions are also constantly evolving. People's requirements for various mobile terminal hardware facilities are also constantly improving. For example, the pixels of tablets and smart phones can also reach the level of digital cameras. , so people are more willing to use tablet computers or smart phones to realize the camera function. [0003] However, the photographing effect of existing tablet computers and smart phones is always inferior to that of digital cameras, because the overall volume of digital cameras is much larger than that of smart phones. Multi-dimensional movement enables digital cameras to implement optical image stabilization (OIS) and tilt-shift photography technologie...
