The All Analytical Of iPhone 4S' photograph
Before the iPhone, there is no other product conference can reach so big influence, the focus crowd and be spread speed are incomparable. Although early on July 5, iPhone 4S can't satisfied by a lot of people, but the upgrade are really hit home.We can say that the kung fu in the blade and the people who special look forward to iPhone5 also have to say "Give me FIVE!"
Where is the upgrade of IPhone 4S and what is best function of it,we will not say much. You may know better than I. Le's say it's function of taking pictures. Words as a digital image editing (note), is very stop before and the pictures of the phone with disdain, even think that is very "unprofessional" performance. But after the iPhone4 appear; I became more and more "unprofessional". Although it is still the photographing result than camera, but do not deny that a radical departure from the "poor" level, our own daily usable level, add rich photos app and convenient share function, it is hard to make people refuse. Note: in this paper, the author is bubble nets digital imaging channel editor
IPhone 4S may be the first phone that in the concept of the digital camera to explain the cell phone video.I will talk about the improvements of photosensitive components, image processing engine and the camera:
The new back type CMOS is 8 million pixel, compared to iPhone4 it has risen by 60%, while the number and the current digital camera up can't be matched, but pixel doesn't stand for everything, the dogma here also don't have to repeat to you. At the same time the photosensitive component is back as the type of the CMOS technology in DC field has been very mature, better by light effect to bring a more excellent pixels control and quality performance, so we hope that it would lead to a better night's performance. At the same time apple still for iPhone 4S increased IR filter, can reduce the sensitivity of the photographic elements on the infrared radiation, improve quality and reduce the problem. But I think this maybe not because of the IR filter joining, it appear too obvious.
The second is the lens, specifically, the iPhone has lens.It is not we usually sense think cell phones which is the kind of similar pinhole camera equipment, it is with relatively strict optical structure, iPhone 4S compared to iPhone4 increase a gold lens, a total of five nuclear lens can be more precise correction incident light, improve picture sharpness, official figures for sharpness increased by 30%. F / 2.4 biggest aperture and 35 mm equivalent to about the focal length, which also let many people listed iPhone 4S (iPhone 4S bumper) as the "humanistic edge tool".
Finally I will say is the image processing engine, actually it is the iPhone 4S (iPhone 4S skins) A5 core as well as the integration of iOS5 system, which can bring image stable, shooting performance of ascension, face recognition, 1080 p video shooting, real-time noise reduction, machines images/video processing and many functions. Here we have to explain that iPhone 4S (cases for iPhone 4S) hardware specifications in the mobile phone is not in the strongest, 10 million pixels with optical zoom level of mobile phone is not yet seen, but the important thing is that with iOS,it let all the impossible become easily.
