The camera of the iPhone 5S against the rest

 comrades iphone5s-01


As many of you well know, yesterday Apple unveiled its new iPhone 5S , an evolution of the iPhone 5 which introduced such innovations as the processor, fingerprint reader and a new and improved camera . This announcement comes at war mobile cameras in the Android world, and it is impossible that one would come to head comparison with the new Sony Xperia Z1 has announced 20.7MP camera trumpeted.

Let’s take a look at what we know about the iPhone’s camera 5S and try to analyze the data that have been given to see if it gets up to the top cameras found on Android or you could even surpass them.

Size Matters

One of the data on which more focused during the presentation yesterday was in the sensor size. What Apple says: The s camera Ensor iPhone 5S measures 1/3.2 “ and is 15% higher than the iPhone 5, which is when we have 1.5 microns each pixel .

Perfect, what does this mean? The image sensors are classified according to various characteristics, but one of the most important is the size, and in that area is where we have to enter all the photosensors that compose it, and each photosensor is a pixel. Now, when we play with two factors (in this case size and number of photosensors) to look for a relationship that gives us the optimum quality . It is not correct to say that the larger the sensor or more pixels have more pixels lower the quality. We explain this further.

By common sense, the more we increase the size of the sensor, photosensors more we get and more pixel resolution will have the camera. This is correct, but if we continue to increase the pixels out of control at the end the effect will be counterproductive and the quality will suffer. This occurs because too photosensors receive worse apelotonar light and give worse results.

What Apple has done, and in my opinion quite rightly, is increase the size of the sensor to 1/3.2 ” without increasing the number of photosensors , so now it is up to each more space, namely 1.5 microns. If they increased the resolution should have gotten more photosensors and light would have been worse. The truth is that 8 Megapixel resolution is good for a camera phone, and is a good decision for the iPhone 5S.

We now come to Xperia Z1, otherwise. Sony has increased significantly the sensor size of this smartphone to 1/2.3 “. To give us the idea Xperia Z1 sensor has a surface of 28.5 mm2 and 15.5 mm2 iPhone 5S, a difference more than considerable. If Sony had kept the 8 Megapixel or 12 Megapixel previous models have wasted a lot of space, and that is the reason I have been able to increase to 20.7 megapixels.

What decision is better? It is too minimize the problem, but increase the sensor size is very important , and Sony has worked there more. A professional camera full frame format has an area of ​​864 mm2, so it’s deceiving to think that there is no need to further increase the size of sensors. It is an extreme case, but you can see that the difference is huge. The secret is to find an optimal, and as a full frame sensor not fit on a smartphone, you have to increase until it can be and improve technologies for it.

Z1 Xperia But not the Android only case. The HTC One has a sensor size 1/3 “, greater than the iPhone 5S.

The idea of ​​increasing the sensor size and resolution of iPhone 5S is correct , but not innovative or revolutionary. In this technical section have done well, but is using a sensor smaller than some of its alternatives, for many area per pixel to offer.

Processing

Let’s be sincere. For a while I was using an iPhone 5 for comparison with Android, view points for and points against iOS and ultimately have a better position when talking to both operating systems.

A of the things that freaked me was the quality of the photographs of this phone, and it caught my attention because from the technical point of view this is a camera that in principle should not stress too much about above many Android terminals.

Where is the catch? In the processing. When light passes through the lens, it focuses on the sensor and this creates an image with electrons, we have a raw photograph that much space and you need compression and graphics processing. And in this part Apple has found a key that makes their terminals resulting always so lightly on the photographic evidence, processing and compression a very good . Samsung is arguably the Android manufacturer that best meets this section, and we can see in the pictures that you take the Galaxy S 4, which uses the same sensor as the Sony Xperia Z.

This is one of the photography key smartphones and Apple does very well . There is much game for Android manufacturers, and if you put the batteries could improve outcomes astronomically.

What makes better pictures?

I’m afraid this is the eternal question and will remain, and unfortunately there is no answer. We segmented into categories and come to certain conclusions, but there is no definitive proof tell us what are the best pictures , and less when it comes to smartphones.

The Photography is light , and the light is dynamic. We will never twice in the same situation and we can never capture two moments equal. Not to mention that to you one result is better and for me it is another, without adding to this the ability photographer you are entrusting to immortalize a moment.

Each manufacturer makes a decision when making a camera and each offers better results and worse conditions in other . In the end it is about what you like best to everyone, much technology may be behind it there is nothing like just being shown on a screen.

Do you think all these camera specifications iPhone 5S make it superior to many models of Android? Or do you think the end is just talk?

NOTE : not put sample photos iPhone 5S because the only evidence that there are controlled and optimal conditions of light, I do not show a real case.
