Background

Photos shot by electronic equipment such as a mobile phone and the like in the shooting process sometimes become invalid, namely, the shot pictures are not clear enough, and double images or blurs occur. These causes, in addition to occasional defocus (i.e., failure of the imaging lens to be in focus), are largely due to slight jitter occurring when the photographic subject is exposed. In general, such a very slight shaking phenomenon often occurs in a handheld condition, and thus, in recent years, there is a relatively large demand for developing an anti-shaking function. Under the background, proposals for the optical anti-shake function of OIS (optical image stabilization system) are increasing, and the micro optical anti-shake technology is gradually adopted by various high-end mobile phones, so that it is expected to effectively reduce the probability of taking blurred pictures in a low-light environment and effectively solve the trouble caused by hand shake in the shooting process.
