Nowadays, many users use mobile phones as communication tools and cameras. The importance of camera performance for mobile phone is self-evident, and it is also an important standard to judge the performance of mobile phone. < / P > < p > when Android manufacturers are chasing each other on the road of high pixel and super large bottom. The iPhone is like an old player, far behind the Android camp. < / P > < p > take the simplest example: both Xiaomi and Samsung have 100 million pixel lenses, and this year, the iPhone 12 is still polishing the 1200 W pixel lens that started with the iPhone 6S; all the happiness of night vision device, moon shooting and telescope belongs to Android, and the iPhone has nothing, even the three shot and night view mode is late last year < p > < p > take last year’s iPhone 11 Pro Series as an example, although a new three camera system has been added. Fluency and experience are impeccable. But the actual photo effect is still instantaneous by the Android camp, and it doesn’t stay in the top 10 of the DxOMark list for long. As a result, in the recent two years of huami ov’s new machine press conference, they disdained the iPhone camera as a competitive product. < / P > < p > all lenses are still 12 million pixels in one water. The main aperture has been upgraded to f1.6 with a new 7p lens. < / P > < p > the long focus end of the iPhone 12 Pro Max supports 5x optical zoom, and the sensor area of the wide-angle camera is increased by 47%. The iPhone 12 Pro supports 4x optical zoom, while the other two iPhones only support 2x optical zoom. < / P > < p > seeing this, many netizens will say: this parameter is still a toothpaste squeeze upgrade, which is far from the Android flagship. Where’s the toothpaste explosion? Don’t worry. It’s coming down here. The full name of lidar is light detection and ranging, and its main function is distance perception of objects. In short, the sensor of ordinary lens directly receives the light from external objects to image, while the lidar is “active detection”, which first emits multi-channel laser. Then the distance information of the object is calculated according to the time when the light meets the object and reflects back. < / P > < p > lidar is currently used more than in the iPhone 12 Pro camera technology. In low light scene, lidar can quickly and accurately calculate the distance between objects. In this way, the camera can be assisted to achieve fast autofocus. And get more in-depth information, so as to perfect the virtual background. < / P > < p > What’s more, lidar can sense the distance of objects in an all black environment. And through the “scanning” area, a “dot matrix” diagram can be formed. Then the computer can synthesize the model of the three-dimensional world through the lattice information. Due to its 3D modeling function, it can be widely used in AR scenes. For example, virtual games, dressing the living room as a rainforest < / P > < p > of course, these are the afterwords. At present, there is only a fast autofocus function. It’s enough to give the iPhone 12 a big shot at night. < / P > < p > the OIS anti shake of traditional mobile phones is to offset the shaking caused by vibration by moving the lens. The sensor shift OIS optical anti shake system on iPhone 12 Pro Max directly designs the whole imaging sensor as anti shake. Fine tune it at a frequency of 5000 times per second, so that the jitter is more thoroughly offset. < p > < p > photographers are familiar with raw format photos. This format can keep more photo information. After being imported into the computer, you can use software such as Lightroom for later adjustment. < / P > < p > while taking photos on the iPhone 12 pro, you can choose to keep it in raw format. And the special apple proraw format can be used to edit raw photos on the mobile phone. This has brought great convenience to the editing work, but also lowered the photography threshold. < / P > < p > in addition, the iPhone 12 is the first phone to record Dolby’s HDR video. And you can directly edit Dolby’s horizon video with your own iMovie on your mobile phone. At the same time, the iPhone 12pro series also supports 4K video capture with up to 60 frames and 10 bit HDR video recording. < / P > < p > so much black technology, plus the unique skill of seamless switching of three shots before. The photo experience of the iPhone 12 series is the best of today’s smartphones. < / P > < p > today’s smart phone photography is far from “take a picture, scan a code” so simple. It successfully took out the card camera and was able to take 100 million pixel photos and more than 4K video. However, due to the size limitation, the development of the camera function of smart phones must be made a trade-off. In this regard, Samsung Xiaomi chose the ultra-high 100 million pixels; Huawei chose the big bottom and large pixels and 10 times optical zoom. However, apple insists on its own unique optimization strategy, which does not seek high pixels and does not shoot the moon. Just make the best of the experience of taking photos – seamless switching of multiple lenses, fast laser focusing, sensor displacement type anti shake and editing the original image on the mobile phone after shooting. However, there are still many photo enthusiasts willing to use the iPhone’s photo feature. Because the opportunity to take photos is really better! Since the iPhone 12 this year, Apple has gradually widened the photo experience gap with the Android camp. < / P > < p > so which solution do you think you like: the high pixel of millet? Or Huawei’s big bottom and big pixels? Or is it Apple’s photo experience first? American companies begin to give up R & D: who should pay for corporate research?
