Apple is also ignorant? What is the iPhone 12's sensor displacement stabilization?

In the early morning of today, Beijing time, Apple officially released 4 mobile phones in the iPhone 12 series. The iPhone 12 standard version and iPhone 12 Mini are good enough, and the two iPhone 12 Pro versions have their own characteristics (the other is the iPhone 12 Pro Max) . But in terms of camera capabilities alone, the strongest one must be the iPhone 12 Pro Max. This is mainly because the three lenses all have a 12-megapixel main camera. Except that the f/2.4 aperture ultra-wide-angle lens is the same as the iPhone 12 Pro, the 26mm wide-angle lens uses the largest photosensitive element in Apple mobile phones so far, and the CMOS area has increased by 47%. , Reaching a size of 1.7um, especially when taking pictures of night scenes, the overall low-light performance is improved by 87%. But what makes me more interested is that the photosensitive element of the iPhone 12 Pro Max also adds Sensor-Shift (sensor shift) anti-shake, which uses the movement of the photosensitive element to enhance the anti-shake effect. According to Apple's official statement, there is no hand-held 2-second exposure. problem.

The difference between iPhone 12 Pro and iPhone 12 Pro Max cameras

However, until I saw the introduction on "Sensor Displacement Image Stabilization" given by Apple's official website, as a person who knew better about the camera, I said that Apple has also become so ignorant? I understand that Apple wants to "leapfrog and touch porcelain" SLR cameras to express the idea that the technology is good enough and professional, but when does the sensor anti-shake become a unique secret that only SLRs have? Panasonic, Olympus, and Sony said: Do you look down on us? Our micro-single is not equipped with a name, right? !

Of course, the iPhone 12 Pro Max has realized "body anti-shake" (sensor displacement anti-shake) for the first time on a mobile phone, which is worth applauding. As a mobile phone, it can be regarded as a technological breakthrough, but the sensor Displacement-type anti-shake is by no means only available for SLRs. Instead, mirrorless cameras take it forward and even become the standard configuration of many professional cameras. Now that we talk about sensor anti-shake, let's talk briefly today, what is this "sensor displacement anti-shake".

First of all, whether it is a camera or a mobile phone, there are currently three mainstream anti-shake technologies: lens optical image stabilization (OIS), electronic image stabilization (EIS), and body anti-shake, which is the new addition to the iPhone 12 Pro Max. Sensor displacement type anti-shake. Prior to this, only high-end models of mobile phones were generally equipped with OIS optical image stabilization. The shift or tilt of the image stabilization component inside the lens was used to compensate for the shift or tilt of the image field, thereby reducing the impact caused by jitter or tilt. Blur, make the photo more clear, Canon IS anti-shake, Nikon VR anti-shake is the case.

Sensor displacement anti-shake, in fact, is the same in principle, but the anti-shake component is not in the lens, but the sensor itself. The earliest use of sensor anti-shake should be Pentax SLR, its representative SR anti-shake is the first generation technology of body anti-shake, but due to technical limitations, only two-axis anti-shake performance is only in the standard focal length for the up and down, left and right shaking. And wide-angle will have some effect, but when using a telephoto lens, it is completely inferior to optical image stabilization, so the technology has stagnated for a long time. It was not until Olympus upgraded the sensor image stabilization to 5-axis image stabilization, which can effectively compensate for the camera roll that cannot be corrected by the built-in lens stabilization, and the horizontal/vertical displacement that easily occurs during macro photography, and the technology has returned to imaging. Field, and quickly spread to M4/3, APS-C and full-frame mirrorless cameras.

This time, the iPhone 12 Pro Max currently only has a 26mm wide-angle lens equipped with "sensor shift type anti-shake", so it does not use a 5-axis anti-shake design. It should be two-axis anti-shake like the previous Pentax SLR, but due to the sensor size Smaller, so the anti-shake performance should have a good performance.

Tucao, this time maybe it’s just that Apple’s wording is not rigorous enough, but this new anti-shake technology can really help us provide a more stable picture when taking pictures and videos. If you are taking pictures and shooting Video to choose the new iPhone, then iPhone 12 Pro Max is definitely the first choice.
