Whether you take photos with a mobile phone or a camera, many times you will find that if you can't hold the device firmly when taking photos, the photos taken are blurry. In order to make up for this defect, various anti shake technologies for cameras have emerged, and mobile phones are no exception.

Now the pixels of some smart phones with high pixel cameras are getting closer and closer to digital cameras. However, compared with digital cameras, mobile phone cameras do not contain some optical or mechanical parts of professional cameras due to the limited volume. This lack of hardware will undoubtedly make the photo taking effect of camera phones worse than that of cameras. In order to further improve the effect of mobile phone photography, we still try to introduce anti shake technology for mobile phone cameras in the space we can.

The introduction of anti shake technology can make the photo taking effect of mobile phones with high pixel cameras more similar to that of cameras. At present, the following anti shake technologies are mainly used for mobile camera: Optical anti shake : Optical Image Stabilizer (OIS for short); Algorithm anti shake. In these two technologies, algorithm anti shake is commonly used. OIS has also been used on flagship mobile phones of several well-known mobile phone manufacturers, such as NOKIA Lumia 920. The following is a brief introduction to these two commonly used anti shake methods for mobile phone cameras.

one 、 OIS

Optical anti shake (OIS for short) relies on the structure of special lens or CCD sensor to minimize the image instability caused by shake during use. As an optical anti shake technology, it does not keep the body from shaking, but relies on the special lens or CCD sensor structure to minimize the image instability caused by shake during the use of the operator. The specific editor has been popularized in the previous article, and you can refer to《 Detailed explanation of optical anti shake of mobile camera 》。

two Algorithm anti shake

Algorithmic anti shake is also called electronic anti shake technology, which uses dynamic vectors in shake detection. Grasp the swing direction and swing amount of the image according to the dynamic vector, and use this as a reference to make the image position move in parallel, so as to generate a dynamic image without jitter.
