With the development of multimedia technology, cameras are widely applied to electronic devices, especially to electronic devices such as mobile phones and tablet computers carried by users, but the situation that the shot pictures are not clear enough and ghosts or blurs always occur often occurs, and the reason for the situation is that the shutter speed is too low.

The OIS (optical anti-shake) is to detect a small movement by a gyroscope in the lens, then transmit a signal to a microprocessor, calculate its compensation displacement, and then compensate according to the shake direction and displacement of the lens by a compensation lens set. Above two kinds of camera anti-shake modes can not reach the multi-direction, wide-angle swing of formation of image module, realize wide-angle anti-shake, and the anti-shake effect is also not obvious.
